Purpose: The present study evaluated whether morphological-measured stromal and intra-tumour tumour-infiltrating lymphocytes (TILs) levels were associated with gene expression profiles, and whether TILs-associated genomic signature (GS) could be used to predict clinical outcomes and response to therapies in several breast cancer subtypes. Methods: We retrospectively evaluated haematoxylin eosin (HE)-TILs levels and gene expression profiling data from 40 patients with primary breast cancer and extracted the 22 overexpressed genes in cases with high TILs scores as the TILs-GS. The TILs-GS were compared with breast cancer subtype and were evaluated predictive values for prognosis and response to therapies. Results: Higher TILs-GS expressions were observed for triple-negative and human epidermal growth factor receptor 2 (HER2) positive (+) breast cancers, compared to the luminal types (P &lt
0.001). With the exception of HER2+, the TILs-GS had no prognostic value in subtypes of breast cancers. The Wilcoxon test revealed significantly different TILs-GS levels between the cases with pathological complete response (pCR) and residual disease after anthracycline and taxane-based neoadjuvant chemotherapy, with the exception of the luminal-low proliferation subtype. In the multivariate analysis, pCR was independently associated with smaller tumour size, higher histological grade, ER negativity, HER2 positivity and higher TILs-GS scores (OR 2.02, 95% CI 1.30–3.14, P = 0.025). Conclusions: TILs-GS was associated with stromal and intra-tumour TILs levels, as evaluated using HE, which predicted prognosis and chemotherapy response in several breast cancer subtypes. Further studies are needed to perform stratification according to TILs-GS levels and the conventional breast cancer subtypes.

Circulating tumor cells (CTC) are newly discovered biomarkers of cancers. Although many systems detect CTC, a gold standard has not yet been established. We analyzed CTC in uterine cervical cancer patients using an advanced version of conditionally replicative adenovirus targeting telomerase-positive cells, which was enabled to infect coxsackievirus-adenovirus receptor-negative cells and to reduce false-positive signals in myeloid cells. Blood samples from cervical cancer patients were hemolyzed and infected with the virus and then labeled with fluorescent anti-CD45 and anti-pan cytokeratin antibodies. GFP (+)/CD45 (-) cells were isolated and subjected to whole-genome amplification followed by polymerase chain reaction analysis of human papillomavirus (HPV) DNA. CTC were detected in 6 of 23 patients with cervical cancers (26.0%). Expression of CTC did not correlate with the stage of cancer or other clinicopathological factors. In 5 of the 6 CTC-positive cases, the same subtype of HPV DNA as that of the corresponding primary lesion was detected, indicating that the CTC originated from HPV-infected cancer cells. These CTC were all negative for cytokeratins. The CTC detected by our system were genetically confirmed. CTC derived from uterine cervical cancers had lost epithelial characteristics, indicating that epithelial marker-dependent systems do not have the capacity to detect these cells in cervical cancer patients.

Adequate iron levels are essential for human health. However, iron overload can act as catalyst for the formation of free radicals, which may cause cancer. Cancer stem cells (CSCs), which maintain the hallmark stem cell characteristics of self-renewal and differentiation capacity, have been proposed as a driving force of tumorigenesis and metastases. In the present study, we investigated the role of iron in the proliferation and stemness of CSCs, using the miPS-LLCcm cell model. Although the anti-cancer agents fluorouracil and cisplatin suppressed the proliferation of miPS-LLCcm cells, these drugs did not alter the expression of stemness markers, including Nanog, SOX2, c-Myc, Oct3/4 and Klf4. In contrast, iron depletion by the iron chelators deferasirox and deferoxamine suppressed the proliferation of miPS-LLCcm cells and the expression of stemness markers. In an allograft model, deferasirox inhibited the growth of miPS-LLCcm implants, which was associated with decreased expression of Nanog and Sox2. Altogether, iron appears to be crucial for the proliferation and maintenance of stemness of CSCs, and iron depletion may be a novel therapeutic strategy to target CSCs.

Background: Small bowel adenocarcinoma (SBA) is a rare malignancy that accounts for 1-2% of gastrointestinal tumours. We investigated the clinical characteristics, outcomes, and prognostic factors of primary SBA.
Methods: We retrospectively analysed the characteristics and clinical courses of 205 SBA patients from 11 institutions in Japan between June 2002 and August 2013.
Results: The primary tumour was in the duodenum and jejunum/ileum in 149 (72.7%) and 56 (27.3%) patients, respectively. Sixty-four patients (43.0%) with duodenal adenocarcinoma were asymptomatic and most cases were detected by oesophagogastroduodenoscopy (EGD), which was not specifically performed for the detection or surveillance of duodenal tumours. In contrast, 47 patients (83.9%) with jejunoileal carcinoma were symptomatic. The 3-year survival rate for stage 0/I, II, III, and IV cancers was 93.4%, 73.1%, 50.9%, and 15.1%, respectively. Multivariate analysis revealed performance status 3-4, high carcinoembryonic antigen, high lactate dehydrogenase (LDH), low albumin, symptomatic at diagnosis, and stage III/IV disease were independent factors for overall survival (OS). Ten patients (18.5%) with stage IV disease were treated with a combination of resection of primary tumour, local treatment of metastasis, and chemotherapy; this group had a median OS of 36.9 months.
Conclusions: Although most SBA patients were diagnosed with symptomatic, advanced stage disease, some patients with duodenal carcinoma were detected in early stage by EGD. High LDH and symptomatic at diagnosis were identified as novel independent prognostic factors for OS. The prognosis of advanced SBA was poor, but combined modality therapy with local treatment of metastasis might prolong patient survival.

Trastuzumab (Tmab), a humanized monoclonal antibody that selectively targets human epidermal growth factor receptor 2 (HER2), is currently used in the clinical setting for the treatment of both breast and gastric cancer. While Tmab has shown improvements in patient prognoses, acquired resistance to this agent remains an issue. While some novel HER2-targeted agents have been approved for clinical use in breast cancer, no such agent has shown treatment efficacy for gastric malignancies with Tmab-resistance. Nanotechnology, which has progressed rapidly, has been applied to medical fields in recent years. Gold nanopartides, which are characterized by their in vivo stability and ease of surface modification, have been reported to show efficacy as the carriers of therapeutic agents, such as drugs, antibodies, peptides, and nucleic acids. In this work, we developed Tmab-conjugated gold nanopartides and demonstrate their efficacy for the treatment of HER2-positive, Tmab-resistant gastric cancer cell lines. Our findings demonstrate that Tmab-conjugated gold nanopartides have the potential to be a novel HER2-targeted therapeutic agent.

Oncolytic virotherapy has the disadvantage of being unsuitable for systemic delivery due to immune elimination. Liposomal encapsulation is well-recognized to reduce immune elimination and enhance the stability of drugs in the bloodstream. In the present study, the potential of liposome-encapsulated plasmid DNA of telomerase-specific oncolytic adenovirus (TelomeScan) expressing GFP (Lipo-pTS) as an oncolytic adenoviral agent suitable for systemic delivery was investigated. Lipo-pTS, which has a diameter of 40-50 nm, showed potent antitumor effects on HCT116 colon carcinoma cells in vitro and in vivo. Tumor selectivity of Lipo-pTS was independent of coxsackie and adenovirus receptor (CAR). Importantly, Lipo-pTS reduced production of adenovirus-neutralizing antibodies (AdNAbs) after intravenous administration into immune-competent mice compared to TelomeScan, and even in the presence of AdNAbs, Lipo-pTS maintained strong cytotoxicity. In conclusion, Lipo-pTS has the potential to become an oncolytic adenoviral agent suitable for systemic delivery with the characteristics of CAR-independent antitumor activity and a stealth effect on the immune system.

Determining the indications for and timing of liver transplantation (LT) for acute liver failure (ALF) is essential. The King's College Hospital (KCH) guidelines and Japanese guidelines are used to predict the need for LT and the outcomes in ALF. These guidelines' accuracy when applied to ALF in different regional and etiological backgrounds may differ. Here we compared the accuracy of new (2010) Japanese guidelines that use a simple scoring system with the 1996 Japanese guidelines and the KCH criteria for living donor liver transplantation (LDLT). We retrospectively analyzed 24 adult ALF patients (18 acute type, 6 sub-acute type) who underwent LDLT in 1998-2009 at our institution. We assessed the accuracies of the 3 guidelines' criteria for ALF. The overall 1-year survival rate was 87.5%. The new and previous Japanese guidelines were superior to the KCH criteria for accurately predicting LT for acute-type ALF (72% vs. 17%). The new Japanese guidelines could identify 13 acute-type ALF patients for LT, based on the timing of encephalopathy onset. Using the previous Japanese guidelines, although the same 13 acute-type ALF patients (72%) had indications for LT, only 4 patients were indicated at the 1st step, and it took an additional 5 days to decide the indication at the 2nd step in the other 9 cases. Our findings showed that the new Japanese guidelines can predict the indications for LT and provide a reliable alternative to the previous Japanese and KCH guidelines.

Immune-nutritional status has been recently reported as a prognostic factor in hepatocellular carcinoma (HCC). The controlling nutritional status (CONUT) score has been established as a useful tool to evaluate immune-nutritional status. This study aimed to investigate the efficacy of the CONUT score as a prognostic factor in patients undergoing hepatectomy for HCC.
A total of 295 patients who underwent curative hepatectomy for HCC between January 2007 and December 2014 were retrospectively analyzed. Patients were divided into two groups according to the CONUT score. The impact of the CONUT score on clinicopathological, surgical, and long-term outcomes was evaluated. Subsequently, the impact of prognostic factors, including the CONUT score, associated with outcomes was assessed using multivariate analyses.
Of 295 patients, 118 (40%) belonged to the high CONUT group (CONUT score 3). The high CONUT group had a significantly lower 5-year recurrence-free survival rate than the low CONUT group (27.9 vs. 41.4%, p = 0.011) and a significantly lower 5-year overall survival rate (61.9 vs. 74.9%, p = 0.006). In multivariate analyses of prognostic factors, the CONUT score was an independent predictor of recurrence-free survival (hazard ratio = 1.64, p = 0.006) and overall survival (hazard ratio = 2.50, p = 0.001).
The CONUT score is a valuable preoperative predictor of survival in patients undergoing hepatectomy for HCC.

Osteosarcoma is an aggressive malignant bone tumor that causes bone destruction. Although tumor-specific replicating oncolytic adenovirus OBP-301 induces an antitumor effect in an osteosarcoma tumor, it cannot prevent bone destruction. Zoledronic acid (ZOL) is a clinically available agent that inhibits bone destruction. In this study, we investigated the potential of combination therapy with OBP-301 and ZOL against osteosarcomas with bone destruction. The antitumor activity of OBP-301 and ZOL in monotherapy or combination therapy was assessed using three human osteosarcoma cell lines (143B, MNNG/HOS, SaOS-2). The cytotoxic effect of OBP-301 and/or ZOL was measured by assay of cell apoptosis. The effect of OBP-301 and ZOL on osteoclast activation was investigated. The potential of combination therapy against tumor growth and bone destruction was analyzed using an orthotopic 143B osteosarcoma xenograft tumor model. OBP-301 and ZOL decreased the viability of human osteosarcoma cells. Combination therapy with OBP-301 and ZOL displayed a synergistic antitumor effect, in which OBP-301 promoted apoptosis through suppression of anti-apoptotic myeloid cell leukemia 1 (MCL1). Combination therapy significantly inhibited tumor-mediated osteoclast activation, tumor growth and bone destruction compared to monotherapy. These results suggest that combination therapy of OBP-301 and ZOL suppresses osteosarcoma progression via suppression of MCL1 and osteoclast activation.

Background: Emerging evidence indicates that small nucleolar RNAs (snoRNAs) play a central role in oncogenesis. Herein, we systematically evaluated expression profiles of snoRNAs in colorectal cancer (CRC) and investigated their clinical and functional role in this malignancy.
Methods: We compared expression levels of snoRNAs between cancer and normal tissues using publicly available datasets and identified the most differentially expressed and commonly upregulated snoRNAs in CRC. These results were examined in 489 colorectal tissues to assess their clinical significance, followed by a series of in vitro and in vivo experiments to evaluate the functional role of candidate snoRNAs.
Results: Usingmultiple RNA profiling datasets, we identified consistent overexpression of SNORA21 in CRC. In the clinical validation cohorts, the expression level of SNORA21was upregulated in colorectal adenomas and cancers. Furthermore, elevated SNORA21 emerged as an independent factor for predicting poor survival. Both in vitro and in vivo experiments revealed that CRISPR/Cas9-mediated inhibition of SNORA21 expression resulted in decreased cell proliferation and invasion through modulation of multiple cancer related pathways.
Conclusions: Wesystematically identified SNORA21 as a key oncogenic snoRNA in CRC, which plays an important role in cancer progression, and might serve as an important prognostic biomarker in CRC. (C) 2017 The Authors. Published by Elsevier B.V.

Purpose Laparoscopy-assisted distal gastrectomy (LADG) is likely to become a standard procedure for gastric cancer, which highlights the importance of establishing a training system in which even inexperienced surgeons can perform this procedure safely. This study assesses our training system for LADG based on short-term surgical outcomes.
Methods We evaluated retrospectively the short-term outcomes of 100 consecutive LADGs with curative D1/D1+ lymph node dissection. Our training system was assessed based on the learning curve of trainees, and factors related to achieving good-quality operations were analyzed statistically.
Results Overall, postoperative complications developed in 10 patients (10%), and included one case of anastomotic leakage (1%) and one case of pancreatic fistula (1%). The learning curve of the trainees plateaued after 10 operator cases in terms of operation time. The importance of the trainer's position was also confirmed by the result that the operation time was significantly longer when trainees with <= 10 operator cases performed LADG with a trainer as scopist vs. a trainer as the first assistant. Univariate and multivariate analyses revealed that > 10 operator cases were the most important factor for achieving good-quality operations.
Conclusion These results show that our current LADG procedure and training system are appropriate and effective.

Purpose: Colorectal cancer is one of themost common malignancies worldwide. Recently, a novel circular RNA, ciRS-7, was proposed to be a potential miR-7 sponge. As miR-7, a putative tumor-suppressor, regulates the expression of several important drivers of colorectal cancer, we analyzed the clinical significance of ciRS-7 in colorectal cancer patients.
Experimental Design: Initially, we evaluated the expression levels of ciRS-7 in a training cohort comprising of 153 primary colorectal cancer tissues and 44 matched normal mucosae. We subsequently confirmed its clinical relevance in an independent validation cohort (n = 165), and evaluated the effect of ciRS-7 on miR-7, and its target genes EGFR and RAF1. Functional analyses were performed in cell lines and an animal model to support clinical findings.
Results: Our data revealed that ciRS-7 was significantly upregulated in colorectal cancer tissues compared with matched normal mucosae (P = 0.0018), and its overexpression was associated with poor patient survival (P = 0.0224 and 0.0061 in the training and validation cohorts, respectively). Multivariate survival analysis revealed that ciRS-7 emerged as an independent risk factor for overall survival (P = 0.0656 and 0.0324 in the training and validation cohorts, respectively). Overexpression of ciRS-7 in HCT116 and HT29 cells led to the blocking of miR-7 and resulted in a more aggressive oncogenic phenotype, and ciRS-7 overexpression permitted the inhibition of miR-7 and subsequent activation of EGFR and RAF1 oncogenes.
Conclusions: CiRS-7 is a promising prognostic biomarker in colorectal cancer patients and may serve as a therapeutic target for reducing EGFR-RAF1 activity in colorectal cancer patients. (C) 2017 AACR.

記述言語：英語出版者・発行元：BIOMED CENTRAL LTD

Background: Although ectopic pancreatic tissue is common in the upper gastrointestinal tract, the incidence of ectopic pancreatic tissue in the jejunum is low, and malignant transformation in ectopic pancreatic tissue is rare. Furthermore, pancreatic-type acinar cell carcinoma (ACC) developing in the jejunum and ACC accompanied by tumor thrombus are extremely rare.
Case presentation: A 78-year-old-woman presented with melena. Abdominal computed tomography images and endoscopic examination revealed a submucosal jejunal mass with tumor thrombus extending into a jejunal vein. The patient underwent a curative resection combined with a partial jejunectomy and partial pancreatectomy. Histopathological examination of the resected tissue showed tumor cells with a homogeneous acinar architecture identical to pancreatic-type ACC and tumor thrombus. Postoperatively, she was followed for 10 months and had no recurrence.
Conclusion: We present an extremely rare case of pancreatic-type ACC in the jejunum with extensive tumor thrombus invading into the mesenteric venous system. This type of cancer has not been reported previously but should be considered in the differential diagnosis of a jejunal mass.

Background: Endoscopic resection (ER) has been widely accepted as the standard treatment for early gastric cancer (EGC). However, in patients considered to have undergone non-curative ER due to their potential risk of lymph node metastasis (LNM), additional gastrectomy is recommended. The aim of the present study was to identify EGC patients after non-curative ER at high risk of LNM.
Methods: A total of 150 patients who had undergone ER for EGC were diagnosed as non-curative ER due to their potential risk of LNM. Clinicopathological data and clinical outcomes were examined retrospectively.
Results: Additional gastrectomy with lymph node dissection was performed in 73 patients, and the remaining 77 patients were followed-up without additional gastrectomy. In patients who underwent additional gastrectomy, 8 patients had local residual tumor, and 8 patients had LNM, which were limited in the peritumoral nodes. Only lymphatic invasion (p = 0.012) was a statistically significant factor for LNM. The 5-year overall survival and recurrence-free survival were not significantly different between patients with and without additional gastrectomy.
Conclusion: Additional gastrectomy with lymph node dissection is recommended for patients who were diagnosed as non-curative ER with lymphatic invasion, and minimizing the extent of lymph node dissection may be allowed for these patients.

記述言語：英語出版者・発行元：BIOMED CENTRAL LTD

Background: Recently, skeletal muscle depletion (sarcopenia) has been reported to influence postoperative outcomes after certain procedures. This study investigated the impact of sarcopenia on postoperative outcomes following pancreaticoduodenectomy (PD).
Methods: We performed a retrospective study of consecutive patients (n = 219) who underwent PD at our institution between January 2007 and May 2013. Sarcopenia was evaluated using preoperative computed tomography. We evaluated postoperative outcomes and the influence of sarcopenia on short-term outcomes, especially infectious complications. Subsequently, multivariate analysis was used to assess the impact of prognostic factors (including sarcopenia) on postoperative infections.
Results: The mortality, major complication, and infectious complication rates for all patients were 1.4%, 16.4%, and 47.0%, respectively. Fifty-five patients met the criteria for sarcopenia. Sarcopenia was significantly associated with a higher incidence of in-hospital mortality (P = 0.004) and infectious complications (P < 0.001). In multivariate analyses, sarcopenia (odds ratio = 3.43; P < 0.001), preoperative biliary drainage (odds ratio = 2.20; P = 0.014), blood loss (odds ratio = 1.92; P = 0.048), and soft pancreatic texture (odds ratio = 3.71; P < 0.001) were independent predictors of postoperative infections.
Conclusions: Sarcopenia is an independent preoperative predictor of infectious complications after PD. Clinical assessment combined with sarcopenia may be helpful for understanding the risk of postoperative outcomes and determining perioperative management strategies.

Laparoscopic and endoscopic cooperative surgery (LECS) is increasingly applied for gastric submucosal tumors (SMTs) such as gastrointestinal stromal tumors. However, the conventional LECS procedure has the potential risk that gastric contents and even tumor cells could spread into the abdominal cavity because the gastric wall has to be opened during the resection. To avoid this problem, we have developed a modified LECS procedure named "closed LECS." Ten patients underwent closed LECS for the resection of gastric SMTs. Closed LECS consists of the following steps: endoscopic submucosal layer dissection around the tumor, laparoscopic marking of a resection line on the serosal surface along submucosal dissection line, seromuscular suturing with the marked lesion inverted into the inside of the stomach, endoscopic circumferential seromuscular dissection, and peroral retrieval. In three of the initial five cases, the closed LECS procedure was not completed as planned because of the tumor size and endoscopic inappropriate seromuscular dissection. After modification of the procedure, the entire procedure was successful in all five cases. The mean resected tumor diameter was 24.1 +/- 7.6 mm. The mean operation time was 253 +/- 45 min. One patient experienced an intra-abdominal abscess potentially related to delayed perforation as a postoperative complication. The closed LECS procedure for gastric SMTs can theoretically be applied without contamination and tumor cell dissemination into the abdominal cavity.

Currently, chemoradiation is the most widely used nonsurgical treatment for esophageal cancer. However, some patients, particularly the very elderly or those with severe vital organ dysfunction, face difficulty with the chemotherapy component. We therefore examined the outcome of radiation therapy (RT) alone for patients with esophageal cancer at our facility. Between January 2005 and December 2014, 84 patients underwent RT at our hospital, and 78 of these patients received concomitant chemotherapy. The remaining 6 patients underwent RT alone; these patients were considered to be high-risk and to have no lymph node metastasis (stage I). Five of them received irradiation up to a curative dose: 4 showed a complete response (CR) and 1 showed a partial response (PR). Of the patients exhibiting CR, 3 are currently living recurrence-free, whereas 1 patient underwent endoscopic submucosal dissection (ESD) as salvage therapy for local recurrence, with no subsequent recurrence. High-risk stage I esophageal cancer patients can be treated radically with RT alone under certain conditions. In the future, to broaden the indications for RT monotherapy to include some degree of advanced cancers, a novel concurrent therapy should be identified.

Background: The purpose of this study was to test whether immunohistochemical (IHC) Ki67 levels after short-term preoperative hormone therapy (post-Ki67) predict similar numbers of patients with favorable prognoses as genomic markers.
Results: Thirty paired cases (60 samples) were enrolled in this study. Post-Ki67 levels were significantly lower than pre-treatment Ki67 levels (P < 0.001). PostKi67 predicted more low-risk cases (83.3%, 25/30) than pre-genomic surrogate signature(GSS) (66.7%: 20/30), but the difference in predictive power was not significant (P = 0.233). Proliferation (MKI67, STK15, Survivin, CCNB1, and MYBL2) and estrogen (ER, PGR, BCL2, and SCUBE2) related signatures were significantly downregulated after therapy (P < 0.001 and 0.041, respectively).
Materials and Methods: Core needle biopsy specimens of primary breast cancer were collected at Okayama University Hospital from hormone receptor-positive and human epidermal growth factor 2-negative patients that subsequently received two weeks of neoadjuvant hormone therapy. Paired post-treatment specimens from surgical samples were also collected. IHC Ki67 levels and GSS were compared between pre-and post-hormone treatment samples. Changes of gene expression pattern in short-term hormone therapy were also assessed.
Conclusions: IHC based post-Ki67 levels may have distinct predictive power compared with the naive IHC Ki67. Future studies with larger cohorts and longer follow-up periods may be needed to validate our results.

We previously developed and characterized a highly invasive and metastatic triple-negative breast cancer (TNBC) variant by serial orthotopic implantation of MDA-MB-231 human breast cancer cells in nude mice. Eventually, a highly invasive and metastatic variant of human TNBC was isolated after lymph node metastases was harvested and orthotopically re-implanted into the mammary gland of nude mice for two cycles. The variant thereby isolated is highly invasive in the mammary gland and metastasized to lymph nodes in 10 of 12 mice compared to 2 of 12 of the parental cell line. In the present report, we observed that high-metastatic MDA-MB-231H-RFP cells produced significantly larger subcutaneous tumors compared with parental MDA-MB-231 cells in nude mice. Extensive lymphatic trafficking by high-metastatic MDA-MB-231 cells was also observed. High-metastatic MDA-MB-231 developed larger recurrent tumors 2 weeks after tumor resection compared with tumors that were not resected in orthotopic models. Surgical resection of the MDA-MB-231 high-metastatic variant primary tumor in orthotopic models also resulted in rapid and enhanced lymphatic trafficking of residual cancer cells and extensive lymph node and lung metastasis that did not occur in the non-surgical mice. These results suggest that surgical resection of high metastatic TNBC can greatly increase the malignancy of residual cancer. J. Cell. Biochem. 118: 559-569, 2017. (c) 2016 Wiley Periodicals, Inc.

Background: Human leukocyte antigen (HLA) mismatch is a characteristic feature of post-orthotopic liver transplantation (OLT) hepatitis C. To investigate the importance of donor HLA-restricted immune cells in post-OLT hepatitis C recurrence, we analyzed the frequency of donor chimerism and the clinical course of post-OLT hepatitis C.
Material/Methods: We analyzed peripheral blood chimerism in 11 HCV-reinfected patients with post-HLA mismatched OLT. Patients were divided into 2 groups: the OLT chronic hepatitis C (CHC) group (n=8), exhibiting active hepatitis C recurrence; and the OLT-persistently normal ALT (PNALT) group (n=3), without active hepatitis. Chimerism was analyzed by flow cytometry using donor-specific anti-HLA antibodies in peripheral blood mononuclear cells from 1-100 days after OLT. Kidney (n=7) and lung (n=7) transplant recipients were also analyzed for comparison. As immune cells from the donor liver might contribute to post-OLT chimerism, the characteristics of perfusates from donor livers (n=10) were analyzed and defined.
Results: Donor-derived cells were frequently observed in liver and lung transplant recipients. The frequency of donor-derived cells from the B cell subset was significantly higher in peripheral blood from OLT-CHC group than in that of the OLT-PNALT group. B cells, however, were not the predominant subset in the perfusates, indicating that inflow of donor-derived cells alone did not cause the chimerism.
Conclusions: Chimerism of B cells is frequent in liver transplant patients with early recurrence of hepatitis C. We propose that monitoring of early chimerism could facilitate early detection of chronic hepatitis C recurrence, although we need more cases to investigate.

記述言語：英語出版者・発行元：WILEY

Background: The external jugular vein (EJV) approach for totally implantable venous access devices (TIVADs) is safe. However, the success rate is unsatisfactory because of the difficulty in catheterization due to the acute angle between the EJV and the subclavian vein (SCV). A novel "shrug technique" to overcome this difficulty was developed, and its efficacy was assessed in a consecutive case series.
Methods: TIVAD placement was performed via the EJV cut-down approach. "Shrug technique," a simple way to straighten the EJV-SVC angle by shrugging the patient's shoulder, was applied to facilitate the passage of the guidewire and sheath-introducer when there was acute angulation between the EJV and SCV.
Results: A total of 254 patients underwent TIVAD implantation by the EJV cut-down approach. The " shrug technique" was applied in 51 cases (20%), and catheterization was successful in all cases. Thus, TIVAD implantation was successfully completed in all 254 cases (100%) in a single operative setting. The median operating time was 38 [IQR 30-45] min. Eleven complications (4%) were observed, but none of them were EJV-specific.
Conclusion: The " shrug technique" is simple but very useful to achieve a higher success rate and safer insertion of TIVADs from the EJV. (C) 2016 Wiley Periodicals, Inc.

We previously described the development of a highly-invasive, triple-negative breast cancer (TNBC) variant using serial orthotopic implantation of MDA-MB-231 human breast cancer in nude mice. The isolated variant is highly invasive in the mammary gland and Metastasized to lymph nodes in 10 of 12 mice compared with 2 of 12 of the parental cell line. OBP-401 is a telomerase-dependent cancer-specific, green fluorescent protein (GFP)-expressing adenovirus. OBP-401 was used to infect parental MDA-MB-231P cells and high-metastatic MDA-MB-231H and MDA-MB-231HLN isolated from a lymph node metastasis and MDA-MB-231HLM isolated from a lung metastasis. Time-course imaging showed that OBP-401 labeled MDA-MB-231HP, MDA-MB-231HLN, and MDA-MB-231HLM cells more brightly than MDA-MB-231 parental cells. OBP-401 killed MDA-MB-231H, MDA-MB-231HLN, and MDA-MB-231HLM cells more efficiently than MDA-MB-231P parental cells. These results indicate that OBP-401 could infect, label and then kill high-metastatic MDA-MB-231 more efficiently than low-metastatic MDA-MB-231.

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is an extremely rare cause of hyponatremia post-liver transplantation. A 15-year-old Japanese girl with recurrent cholangitis after Kasai surgery for biliary atresia underwent successful living donor liver transplantation. Peritonitis due to gastrointestinal perforation occurred. Hyponatremia gradually developed but improved after hypertonic sodium treatment. One month later, severe hyponatremia rapidly recurred. We considered the hyponatremia's cause as SIADH. We suspected that tacrolimus was the disease's cause, so we used cyclosporine instead, plus hypertonic sodium plus water intake restriction, which improved the hyponatremia. Symptomatic hyponatremia manifested by SIADH is a rare, serious complication post-liver transplantation.

Background: Triple-negative breast cancer (TNBC), defined by the absence of receptors for estrogen, progesterone and human epithelial receptor 2, is a recalcitrant disease in need of effective therapy. We previously isolated highly-metastatic variants of the human TNBC cell line MDA-MB-231 using serial orthotopic implantation in nude mice. Materials and Methods: In the present report, we compared local and metastatic recurrence in lymph nodes in orthotopic nude-mouse models after bright-light surgery (BLS) of tumors from highly-metastatic variants or poorly-metastatic parental MDA-MB-231-RFP cells. Orthotopic tumors from parental MDA-MB-231 or highly-metastatic MDA-MB-231 were resected under bright light similar to an operating room. Results: After resection of primary tumors, local recurrence from highly-metastatic MDA-MB-231 cells grew more rapidly than did parental MDA-MB-231 cells. Lymph-node metastasis from highly-metastatic MDA-MB-231 cells occurred after primary tumor resection much more extensively than after parental MDAMB- 231 tumors were resected. Conclusion: The results of the present report suggest that conventional surgery under bright light was unable to control highly-metastatic compared with poorly-metastatic MDA-MB-231 TNBC.

Oncolytic viruses have been receiving much attention as potential agents for cancer treatment. Among the various types of oncolytic viruses, the telomerase-specific replication-competent adenovirus (TRAD), which carries the tumor-specific promoter- driven E1 gene expression cassette, exhibits efficient antitumor effects. The development of a novel TRAD that shows higher replication efficiency and antitumor activity would be highly beneficial for safer and more efficient cancer therapy. We recently demonstrated that the endoribonuclease Dicer significantly inhibits the replication of wild-type adenovirus (Ad) via the processing of viral-associated (VA)-RNAs, which are Ad-encoded small noncoding RNAs, and that the knockdown of Dicer leads to enhanced VA-RNA expression and Ad replication after infection with wild-type Ad. Based on these findings, we herein developed a novel TRAD expressing shorthairpin RNA against Dicer (shDicer; TRAD-shDicer). After infection, TRAD-shDicer efficiently induced the knockdown of Dicer. TRAD-shDicer showed significantly higher replication efficiency and tumor cell lysis activity compared with the conventional TRAD in tumor cells. The Dicer expression levels and viabilities of normal cells were not altered by infection with TRAD-shDicer. These results indicate that TRAD-shDicer is a potent antitumor reagent by virtue of its enhanced oncolytic activity. (C) 2016 AACR.

We previously conducted a phase I clinical trial combining the HLA-A*2402-restricted KIF20A-derived peptide vaccine with gemcitabine for advanced pancreatic cancer (PC) and confirmed its safety and immunogenicity in cancer patients. In this study, we conducted a multicenter, single-armed, phase II trial using two antiangiogenic cancer vaccines targeting VEGFR1 and VEGFR2 in addition to the KIF20A peptide. We attempted to evaluate the clinical benefit of the cancer vaccination in combination with gemcitabine. Chemotherapy naive PC patients were enrolled to evaluate primarily the 1-year survival rate, and secondarily overall survival (OS), progression free survival (PFS), response rate (RR), disease control rate (DCR) and the peptide-specific immune responses. All enrolled patients received therapy without the HLA-A information, and the HLA genotypes were used for classification of the patients. Between June 2012 and May 2013, a total of 68 patients were enrolled. No severe systemic adverse effects of Grade 3 or higher related to these three peptides were observed. The 1-year survival rates between the HLA-A*2402-matched and -unmatched groups were not significantly different. In the HLA-A*2402 matched group, patients showing peptide-specific CTL induction for KIF20A or VEGFR1 showed a better prognosis compared to those without such induction (P = 0.023, P = 0.009, respectively). In the HLA-A*2402-matched group, the patients who showed a strong injection site reaction had a better survival rate (P = 0.017) compared to those with a weak or no injection site reaction. This phase II study demonstrated that this therapeutic peptide cocktail might be effective in patients who demonstrate peptide-specific immune reactions although predictive biomarkers are needed for patient selection in its further clinical application.

Background Operative mortality and morbidity rates after hepato-biliary-pancreatic (BILI) surgery remain high. This study evaluated clinical characteristics and surgical outcomes of patients who underwent BILI surgery and investigated predictors of outcomes by focusing on sarcopenia. Materials and methods A prospective observational study was performed for consecutive patients who underwent BILI surgery at our institution between June 2013 and May 2014. Sarcopenia was evaluated using computed tomography. Surgical outcomes and the influence of sarcopenia on outcomes were evaluated. Subsequently, the impact of prognostic factors, including sarcopenia, associated with postoperative infections was assessed using multivariate analyses. Results Total mortality, major complications, and infectious disease rates for all 157 patients were 0%, 9.6%, and 21.7%, respectively. Thirty-eight patients met the criteria for sarcopenia. The sarcopenic group had a significantly higher incidence of infectious complications compared to the non-sarcopenic group (36.8% vs. 17.2%
P = 0.015). During multivariate analyses of prognostic factors, sarcopenia (hazard ratio = 2.44
P = 0.043) and diabetes mellitus (hazard ratio = 3.07
P = 0.01) were detected as independent predictors of postoperative infections. Conclusions Sarcopenia is an independent preoperative predictor of infection after BILI surgery. Earlier diagnosis and therapeutic intervention for patients with sarcopenia could be useful in the development of comprehensive approaches for perioperative care.

We previously demonstrated that quiescent cancer cells in a tumor are resistant to conventional chemotherapy as visualized with a fluorescence ubiquitination cell cycle indicator (FUCCI). We also showed that proliferating cancer cells exist in a tumor only near nascent vessels or on the tumor surface as visualized with FUCCI and green fluorescent protein (GFP)-expressing tumor vessels. In the present study, we show the relationship between cell-cycle phase and chemotherapy-induced tumor angiogenesis using in vivo FUCCI real-time imaging of the cell cycle and nestin-driven GFP to detect nascent blood vessels. We observed that chemotherapy-treated tumors, consisting of mostly of quiescent cancer cells after treatment, had much more and deeper tumor vessels than untreated tumors. These newly-vascularized cancer cells regrew rapidly after chemotherapy. In contrast, formerly quiescent cancer cells decoyed to S/G(2) phase by a telomerase-dependent adenovirus did not induce tumor angiogenesis. The present results further demonstrate the importance of the cancer-cell position in the cell cycle in order that chemotherapy be effective and not have the opposite effect of stimulating tumor angiogenesis and progression.

When planning surgery for achalasia, it is important to plan for adequate myotomy and prevention of reflux. However, achalasia may recur if the procedure was inadequate or in patients with a long-term course. The present case is a 68-year-old woman who underwent myotomy of the lower esophageal sphincter 40 years ago, but recently reported difficulty in swallowing. Dilatation of the thoracic esophagus and stenosis of the abdominal esophagus were identified by examination, and the patient was diagnosed with recurrence of achalasia. After percutaneous endoscopic gastrostomy was performed to recover nutritional status, thoracoscopic esophagectomy was carried out. The patient's post-operative course was uneventful and oral intake was enabled. At the time of writing, there has been no re-recurrence. There is no standard therapy for post-operative recurrence of achalasia. We believe that thoracoscopic esophagectomy for the recurrence of achalasia is a safe and minimally invasive alternative to conventional surgery.

Introduction Pancreaticoduodenectomy (PD) combined with extended right hemicolectomy (RH) is a challenging procedure for locally advanced malignancies. However, information concerning the reconstruction method of the digestive system is limited. Here, we present a case and surgical technique of a novel intestinal rotation method for digestive reconstruction after PD combined with RH. Presentation of case A 62-year-old man with locally advanced pancreatic cancer received conversion surgery combined with PD and RH after preoperative chemotherapy. With respect to the reconstruction of the digestive system, the entire intestinal mesentery was rotated 180° forward counterclockwise around the axis of the superior mesenteric artery, and then the reconstruction, according to Child's method, was performed. The patient recovered without problems in gastroenterological functions after the operation. Discussion With respect to the reconstruction of the digestive system in patients undergoing combined PD and RH, practitioners should pay close attention to twisting of the intestinal mesentery when bringing up the proximal jejunum for pancreatojejunostomy and hepatojejunostomy and the distal ileum for ileocolic anastomosis. This intestinal rotation method enables a smooth and uneventful reconstruction of the digestive system. Conclusion This is the first detailed description of an intestinal rotation method for digestive reconstruction after combined PD and extended RH. The intestinal rotation method can be an alternative and helpful technical option for digestive reconstruction in patients with combined PD and RH.

Melanoma is a highly recalcitrant cancer and transformative therapy is necessary for the cure of this disease. We recently developed a telomerase-dependent adenovirus containing the fluorescent protein Killer-Red. In the present report, we first determined the efficacy of Killer-Red adenovirus combined with laser irradiation on human melanoma cell lines in vitro. Cell viability of human melanoma cells was reduced in a dose-dependent and irradiation-time-dependent manner. We used an intradermal xenografted melanoma model in nude mice to determine efficacy of the Killer-Red adenovirus. Intratumoral injection of Killer-Red adenovirus, combined with laser irradiation, eradicated the melanoma indicating the potential of a new paradigm of cancer therapy.

Aim: Triple-negative breast cancer (TNBC), defined by the absence of receptors for estrogen, progesterone and human epithelial receptor 2 (HER2), is a recalcitrant disease in need of effective therapy. We previously isolated very-highly metastatic variants of the TNBC cell line MDA-MB-231 using serial orthotopic implantation of MDA-MB-231 human breast cancer cells in nude mice. Materials and Methods: MDA-MB-231 cells expressing red fluorescent protein (MDA-MB-231-RFP) (1x10(7) cells/site) were initially injected subcutaneously in the flank of nude mice. After the subcutaneous tumors grew, they were harvested and cut into small pieces for orthotopic implantation into the right lower mammary gland. After the orthotopic tumors grew, they were resected and cut into small pieces and orthotopically re-implanted into the mammary gland of nude mice. The tumors grew and metastasized to lymph nodes. The lymph node metastases were harvested and cut into small pieces and orthotopically re-implanted into the mammary gland of nude mice. After the orthotopic tumors grew, the tumor was removed leaving residual cancer cells, which grew and metastasized to lymph nodes. The lymph node metastases were harvested, cut into pieces and orthotopically re-implanted into the mammary gland of nude mice for three or seven cycles in order to isolate intermediately, or highly-metastatic variants, respectively. Results: The degree of malignancy of isolated variants of MDA-MB-231 depends on the extent of orthotopic transplantation. Serial transplantation resulted in MDA-MB-231-RFP which significantly produced larger tumors compared with the parental MDA-MB-231-RFP. Serial orthotopic implantation for three cycles resulted in intermediately-metastatic variants of MDA-MB-231-RFP. MDA-MB-231-RFP serially orthotopically transplanted seven times significantly metastasized more to lymph nodes compared with parental MDA-MB-231-RFP cells and the intermediately-metastatic variant. The highly-metastatic variant MDA-MB-231-RFP cells significantly metastasized to the lung to a greater extent compared with parental MDA-MB-231-RFP and intermediate variants of MDA-MB-231-RFP. Conclusion: These results suggest that the number of serial orthotopic transplantations of MDA-MB-231-RFP correlates positively with tumor aggressiveness, and the intermediately- and highly-metastatic variants can serve as models of metastatic progression of TNBC.

Intrahepatic arterioportal fistula (IAPF) is a rare cause of portal hypertension that is often difficult to treat with interventional radiology or surgery. Liver transplantation for IAPF is extremely rare. We report a case of bilateral diffuse IAPF with severe portal hypertension requiring deceased donor liver transplantation (DDLT). A 51-year-old woman with no past medical history was admitted to another hospital complaining of abdominal distension and marasmus. A computed tomography scan and digital subtraction angiography indicated a massive pleural effusion, ascites, and a very large IAPF. Several attempts of interventional embolization of the feeding artery failed to ameliorate arterioportal shunt flow. As ruptures of the esophageal varices became more frequent, hepatic encephalopathy worsened. After repeated, uncontrollable attacks of hepatic coma, the patient was referred to our facility for further treatment. Surgical approaches to IAPF other than liver transplantation were challenging because of diffuse collateralization; therefore, we placed the patient on the national waiting list for DDLT. Although her Model for End-Stage Liver Disease score was relatively low, she received a DDLT 2 months after the waiting period. The postoperative course was uneventful, and the patient was discharged 44 days after her transplant. Liver transplantation may be a valid treatment option for uncontrollable IAPF with severe portal hypertension.

Our laboratory previously developed a highly-invasive, triple-negative breast cancer (TNBC) variant using serial orthotopic implantation of the human MDA-MB-231 cell line in nude mice. The isolated variant was highly-invasive in the mammary gland and lymphatic channels and metastasized to lymph nodes in 10 of 12 mice compared to 2 of 12 of the parental cell line. In the present study, the tumor-selective telomerase dependent OBP-401 adenovirus was injected intratumorally (i. t.) (1 x 10(8) PFU) when the high-metastatic MDA-MB-231 primary tumor expressing red fluorescent protein (MDA-MB-231-RFP) reached approximately 500 mm3 (diameter; 10 mm). The mockinfected orthotopic primary tumor grew rapidly. After i. t. OBP-401 injection, the growth of the orthotopic tumors was arrested. Six weeks after implantation, the fluorescent area and fluorescence intensity showed no increase from the beginning of treatment. OBP-401 was then injected into high-metastatic MDA-MB-231-RFP primary orthotopic tumor growing in mice which already had developed metastasis within lymphatic ducts. All 7 of 7 control mice subsequently developed lymph node metastasis. In contrast, none of 7 mice which received OBP-401 had lymph node metastasis. Seven of 7 control mice also had gross lung metastasis. In contrast, none of the 7 mice which received OBP-401 had gross lung metastasis. Confocal laser microscopy imaging demonstrated that all control mice had diffuse lung metastases. In contrast, all 7 mice which received OBP-401 only had a few metastatic cells in the lung. OBP-401 treatment significantly extended survival of the treated mice.

We have previously developed a genetically-engineered GFP-expressing telomerase-dependent adenovirus, OBP-401, which can selectively illuminate cancer cells. In the present report, we demonstrate that targeting a triple-negative highinvasive human breast cancer, orthotopically-growing in nude mice, with OBP-401 enables curative fluorescence-guided surgery (FGS). OBP-401 enabled complete resection and prevented local recurrence and greatly inhibited lymph-node metastasis due to the ability of the virus to selectively label and subsequently kill cancer cells. In contrast, residual breast cancer cells become more aggressive after bright (white)light surgery (BLS). OBP-401-based FGS also improved the overall survival compared with conventional BLS. Thus, metastasis from a highly-aggressive triple-negative breast cancer can be prevented by FGS in a clinically-relevant mouse model.

"Cell-in-cell" denotes an invasive phenotype in which one cell actively internalizes in another. The novel human T-cell line HOZOT, established from human umbilical cord blood, was shown to penetrate a variety of human cancer cells but not normal cells. Oncolytic viruses are emerging as biological therapies for human cancers; however, efficient viral delivery is limited by a lack of tumor-specific homing and presence of pre-existing or therapy-induced neutralizing antibodies. Here, we report a new, intriguing approach using HOZOT cells to transmit biologics such as oncolytic viruses into human cancer cells by cell-in-cell invasion. HOZOT cells were successfully loaded via human CD46 antigen with an attenuated adenovirus containing the fiber protein of adenovirus serotype 35 (OBP-401/F35), in which the telomerase promoter regulates viral replication. OBP-401/F35-loaded HOZOT cells were efficiently internalized into human cancer cells and exhibited tumor-specific killing by release of viruses, even in the presence of anti-viral neutralizing antibodies. Moreover, intraperitoneal administration of HOZOT cells loaded with OBP-401/F35 significantly suppressed peritoneally disseminated tumor growth in mice. This unique cell-in-cell property provides a platform for selective delivery of biologics into human cancer cells, which has important implications for the treatment of human cancers.

Esophageal carcinomas often have a poor prognosis due to early lymph node metastasis. Epithelial-mesenchymal transition (EMT) is strongly associated with the acquisition of cancer metastasis and invasion. However, there is no established treatment to eliminate the EMT of cancer cells. Iron is an essential element for both normal and cancer cells in humans. Recently, iron depletion has been discovered to suppress tumor growth. Therefore, we hypothesized that decreased iron conditions would regulate EMT phenotypes, as well as suppressing tumor growth. The human TE esophageal cancer cell lines and OE19 were used in our study. Decreased iron conditions were made using an iron-depletion diet in mice and the iron chelator deferasirox for cell studies. Migration and invasion abilities of cells were measured using migration, invasion, and sphere formation assays. Esophageal subcutaneous tumor growth was suppressed in decreased iron conditions. In vitro study showed that decreased iron conditions inhibited esophageal cancer cell proliferation as well as migration and invasion abilities, with downregulation of N-cadherin expression. Also, migration and invasion abilities were suppressed by inhibiting expression of N-cadherin. In conclusion, decreased iron conditions revealed a profound anticancer effect by the suppression of tumor growth and the inhibition of migration and invasion abilities via N-cadherin.

Sarcopenia following liver surgery has been reported as a predictor of poor prognosis. Here we investigated predictors of outcomes in patients with hepatocellular carcinoma (HCC) and attempted to establish a new comprehensive preoperative assessment protocol. We retrospectively analyzed the cases of 254 patients who underwent curative hepatectomy for HCC with Child-Pugh classification A at our hospital between January 2007 and December 2013. Sarcopenia was evaluated by computed tomography measurement. The influence of sarcopenia on outcomes was evaluated. We used multivariate analyses to assess the impact of prognostic factors associated with outcomes, including sarcopenia. Of the 254 patients, 118 (46.5) met the criteria for sarcopenia, and 32 had an American Society of Anesthesiologists (ASA) physical status >= 3. The sarcopenic group had a significantly lower 5-year overall survival rate than the non-sarcopenic group (58.2 vs. 82.4, p=0.0002). In multivariate analyses of prognostic factors, sarcopenia was an independent predictor of poor survival (hazard ratio [HR]= 2.28, p= 0.002) and poor ASA status (HR= 3.17, p= 0.001). Sarcopenia and poor ASA status are independent preoperative predictors for poor outcomes after hepatectomy. The preoperative identification of sarcopenia and ASA status might enable the development of comprehensive approaches to assess surgical eligibility.

Although intermittent pneumatic compression (IPC) has become common as perioperative prophylaxis for venous thromboembolism (VTE) consisting of pulmonary thromboembolism (PE) and deep vein thrombosis (DVT), the prophylactic effect against VTE, especially lethal PE, is not yet satisfactory. Therefore, pharmacologic prophylaxis, such as with enoxaparin, is desirable. While the efficacy and safety of enoxaparin have been proven in several clinical trials, concern about bleeding with long-term (at least 7 days) use have potentially decreased its widespread adoption. We have launched a phase II study to evaluate the efficacy and safety of short-term (3 days) enoxaparin, in which a total of 70 gastric cancer patients undergoing gastrectomy will be recruited, and the primary endpoint is the incidence of DVT. This study could contribute to making pharmacologic prophylaxis for VTE more common.

Stomach cancer carcinomatosis peritonitis (SCCP) is a recalcitrant disease. The goal of the present study was to establish an in vitro-in vivo-like imageable model of SCCP to develop cell-cycle-based therapeutics of SCCP. We established 3-D Gelfoam (R) histoculture and tumor-sphere models of SCCP. FUCCI-expressing MKN-45 stomach cancer cells were transferred to express the fluorescence ubiquinized cell-cycle indicator (FUCCI). FUCCI-expressing MKN-45 cells formed spheres on agarose or on Gelfoam (R) grew into tumor-like structures with G(0)/G(1) cancer cells in the center and S/G(2) cancer cells located in the surface as indicated by FUCCI imaging when the cells fluoresced red or green, respectively. We treated FUCCI-expressing cancer cells forming SCCP tumors in Gelfoam (R) histoculture with OBP-301, cisplatinum (CDDP), or paclitaxel. CDDP or paclitaxel killed only cycling cancer cells and were ineffective against G1/G2 MKN-45 cells in tumors growing on Gelfoam (R). In contrast, the telomerase-dependent adenovirus OBP-301 decoyed the MKN45 cells in tumors on Gelfoam (R) to cycle from G(0)/G(1) phase to S/G(2) phase and reduced their viability. CDDP-or paclitaxel-treated MKN-45 tumors remained quiescent and did not change in size. In contrast, OB-301 reduced the size of the MKN-45 tumors on Gelfoam 1. We examined the cell cycle-related proteins using Western blotting. CDDP increased the expression of p53 and p21 indicating cell cycle arrest. In contrast, OBP-301 decreased the expression of p53 and p21 Furthermore, OBP-301 increased the expression of E2F and pAkt as further indication of cell cycle decoy. This 3-D Gelfoam (R) histoculture and FUCCI imaging are powerful tools to discover effective therapy of SCCP such as OBP-301.

Aim: We describe the development of a highly-invasive, triple-negative breast cancer (TNBC) variant using serial orthotopic implantation of MDA-MB-231 human breast cancer in nude mice. Materials and Methods: MDA-MB-231 cells expressing red fluorescent protein (RFP) (1x10(7) cells/site) were initially injected subcutaneously in the flank of nude mice. After the subcutaneous tumors grew, they were harvested and cut into small pieces for orthotopic implantation in the right lower mammary gland. After the orthotopic tumors grew, they were resected and cut into small pieces and orthotopically reimplanted into the mammary gland of nude mice. The tumors grew and metastasized to lymph nodes. The lymph node metastases were harvested and cut into small pieces and orthotopically re-implanted into the mammary gland of nude mice. After the orthotopic tumors grew, the tumor was removed leaving residual cancer cells, which grew and metastasized to lymph nodes. The lymph node metastases were harvested, cut into pieces and orthotopically re-implanted into the mammary gland of nude mice for two cycles and then isolated. Results: The isolated variant is highly invasive in the mammary gland and metastasized to lymph nodes in 10 of 12 mice compared to 2 of 12 of the parental cell line. Conclusion: The availability of a highly invasive variant of TNBC targeting lymph nodes will be very useful for drug discovery of TNBC, a recalcitrant cancer and for mechanistic studies of its aggressiveness.

Although limited understanding exists for the presence of specific genetic mutations and aberrantly methylated genes in pancreatobiliary intraductal papillary mucinous neoplasms (IPMNs), the fundamental understanding of the dynamics of methylation expansion across CpG dinucleotides in specific gene promoters during carcinogenesis remains unexplored. Expansion of DNA methylation in some gene promoter regions, such as EFEMP1, one of the fibulin family, with tumor progression has been reported in several malignancies. We hypothesized that DNA hypermethylation in EFEMP1 promoter would expand with the tumor grade of IPMN.
A sample of 65 IPMNs and 30 normal pancreatic tissues was analyzed. IPMNs were divided into the following three subsets according to pathological findings: 31 with low-grade dysplasia (low grade), 11 with high-grade dysplasia (high grade), and 23 with associated invasive carcinoma (invasive Ca). Mutations in the KRAS or GNAS genes were analyzed by Sanger sequencing, and methylation status of two discrete regions within the EFEMP1 promoter, namely region 1 and region 2, was analyzed by bisulfite sequencing and fluorescent high-sensitive assay for bisulfite DNA (Hi-SA). Expression status of EFEMP1 was investigated by immunohistochemistry (IHC).
KRAS mutations were detected in 39, 55, and 70 % of low-grade, high-grade, and invasive Ca, respectively. GNAS mutations were observed in 32, 55, and 22 % of low-grade, high-grade, and invasive Ca, respectively. The methylation of individual regions (region 1 or 2) in the EFEMP1 promoter was observed in 84, 91, and 87 % of low-grade, high-grade, and invasive Ca, respectively. However, simultaneous methylation of both regions (extensive methylation) was exclusively detected in 35 % of invasive Ca (p = 0.001) and five of eight IPMNs (63 %) with extensive methylation, whereas 20 of 57 (35.1 %) tumors of unmethylation or partial methylation of the EFEMP1 promoter region showed weak staining EFEMP1 in extracellular matrix (p = 0.422). In addition, extensive EFEMP1 methylation was particularly present in malignant tumors without GNAS mutations and associated with disease-free survival of patients with IPMNs (p < 0.0001).
Extensive methylation of the EFEMP1 gene promoter can discriminate invasive from benign IPMNs with superior accuracy owing to their stepwise accumulation of tumor progression.

Osteosarcoma is a rare disease diagnosed as malignant bone tumor. It is generally refractory to chemotherapy, which contributes to its poor prognosis. The reversal of chemoresistance is a major clinical challenge to improve the prognostic outcome of osteosarcoma patients. We developed a tumor-specific replication-competent oncolytic adenovirus, OBP-301 (telomelysin) and assessed its synergistic effects with chemotherapeutic agents (cisplatin and doxorubicin) using human osteosarcoma cell lines and a xenograft tumor model. The molecular mechanism underlying the chemosensitizing effect of OBP-301 was evaluated in aspects of apoptosis induction. OBP-301 inhibits anti-apoptotic myeloid cell leukemia 1 (MCL1) expression, which in turn leads to chemosensitization in human osteosarcoma cells. The siRNA-mediated knockdown of MCL1 expression sensitized human osteosarcoma cells to common chemotherapeutic agents. We also found that upregulation of microRNA-29 targeting MCL1 via virally induced transcriptional factor E2F-1 activation was critical for the enhancement of chemotherapy-induced apoptosis in osteosarcoma cells. Telomerase-specific oncolytic adenovirus synergistically suppressed the viability of human osteosarcoma cells in combination with chemotherapeutic agents. The combination treatment also significantly inhibited tumor growth, as compared to monotherapy, in an osteosarcoma xenograft tumor model. Our data suggest that replicative virus-mediated tumor-specific MCL1 ablation may be a promising strategy to attenuate chemoresistance in osteosarcoma patients.

A 69-year-old man underwent endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) at the lesser curvature in the angle of stomach. Histological examination revealed tub1, pM, ly0, v0, pLM(-), pVM(-), and the resection was considered curative. The scar after ESD was followed by esophagogastroduodenoscopy (EGD) and biopsy. Twenty months later, EGD showed an ulcerative lesion in the vicinity of the ESD scar, and histological examination of the biopsy specimen showed adenocarcinoma. A distal gastrectomy with lymph node dissection was then performed. Postoperative pathology showed tub1, pM, pN0, ly0, v0, and Stage 1A. Skip lesions were seen in the specimen resected by ESD, and the histological review confirmed so-called "dysplasia-like atypia" (DLA) between the lesions. It has been reported recently that in DLA, the dysplasia-like change involves only the bases of the pits, without upper pit or surface epithelium involvement, and it is said that the rate of DLA is higher in gastric cancer patients. We speculated that a precancerous lesion close to the resected cancer developed into a local recurrence.

In a previous study, we developed fluorescence-guided surgery (FGS) for osteosarcoma using an orthotopic model with 143B human osteosarcoma cells expressing red fluorescent protein (RFP) implanted into the intramedullary cavity of the tibia in nude mice. The FGS-treated mice had a significantly higher disease-free survival (DFS) rate than the bright-light surgery (BLS). However, although FGS significantly reduced the recurrence of the primary tumor, it did not reduce lung metastasis. In the present study, we utilized the OBP-401 telomerase-dependent killer-reporter adenovirus, carrying green fluorescent protein (GFP), to label human osteosarcoma in situ in orthotopic mouse models. OBP-401-illuminated human osteosarcoma cell lines, 143B and MNNG/HOS cells in vitro and in vivo. OBP-401 tumor illumination enabled effective FGS of the 143B-derived orthotopic mouse model of human osteosarcoma model as well as FGS eradication of residual cancer cells after BLS. OBP-401-assisted FGS significantly inhibited local recurrence and lung metastasis after surgery, thereby prolonging DFS and overall survival (OS), achieving a very important improvement of therapeutic outcomes over our previously reported FGS study. These therapeutic benefits of FGS were demonstrated using a clinically-viable methodology of direct labeling of human osteosarcoma in situ with the OBP-401 killer-reporter adenovirus in contrast with previous reports, which used genetically engineered labeled cells or antibody-based fluorescent labels for FGS.

Using the Postgastrectomy Syndrome Assessment Scale (PGSAS)-45, we compared the surgical outcomes and the quality of life (QOL) between patients undergoing limited gastrectomies and those undergoing conventional gastrectomies. In Oomoto Hospital between January 2004 and December 2013, a total of 124 patients who met the eligibility criteria were enrolled. Using the main outcome measures of PGSAS-45, we compared 4 types of limited gastrectomy procedures (1/2 distal gastrectomy [1/2DG] in 21 patients; pylorus-preserving gastrectomy [PPG] in 15 patients; segmental gastrectomy [SG] in 26 patients; and local resection [LR] in 13 patients) with conventional gastrectomy (total gastrectomy [TG] in 24 patients and 2/3 or more distal gastrectomy [WDG] in 25 patients). The TG group showed the worst QOL in almost all items of the main outcome measures. The 1/2DG, PPG, and SG groups showed better QOL than the WDG group in many of the main outcome measures, including the body weight ratio, total symptom score, ingested amount of food per meal, and the dissatisfaction for daily life subscale. The LR group showed a better intake of food than the 1/2DG, PPG, and SG groups. The body weight ratio of the LR group was better than that of the SG group. Diminished gastric resection preserved better QOL in patients with early gastric cancer.

Malignant melanoma requires precise resection in order to avoid metastatic recurrence. We report here that the telomerase-dependent, green fluorescent protein (GFP)-containing adenovirus OBP-401 could label malignant melanoma with GFP in situ in orthotopic mouse models. OBP-401-based fluorescence-guided surgery (FGS) resulted in the complete resection of malignant melanoma in the orthotopic models, where conventional bright-light surgery (BLS) could not. High-dose administration of OBP-401 enabled FGS without residual cancer cells or recurrence, due to its dual effect of cancer-cell labeling with GFP and killing.

Peritoneal dissemination is the most frequent metastasis in gastric cancer and is associated with poor prognosis. The lack of particular target antigens in gastric cancer other than HER2 has hampered the development of treatments for peritoneal dissemination of gastric cancer. Wehypothesized that HER2-extracellular domain (HER2-ECD) gene transduction combined with trastuzumab-based photoimmunotherapy (PIT) might provide excellent and selective antitumor effects for peritoneal dissemination of gastric cancer. In vitro, adenovirus/HER2-ECD (Ad/HER2-ECD) efficiently transduced HER2-ECD into HER2-negative gastric cancer cells. Trastuzumab-IR700 (Tra-IR700)-mediated PIT induced selective cell death of HER2-ECD-transduced tumor cells. Ad/HER2-ECD also induced homogenous expression of HER2 in heterogeneous gastric cancer cells, resulting in uniform sensitivity of the cells to Tra-IR700-mediated PIT. Anti-HER2 PIT integrated with adenoviral HER2-ECD gene transfer was applied in mice bearing peritoneal dissemination of HER2-negative gastric cancer. Intraperitoneal administration of Ad/HER2-ECD and Tra-IR700 with PIT inhibited peritoneal metastasis and prolonged the survival of mice bearing MKN45. Furthermore, minimal side effects allowed the integrated therapy to be used repeatedly, providing better control of peritoneal dissemination. In conclusion, the novel therapy of molecular-targeted PIT integrated with gene transfer technology is a promising approach for the treatment of peritoneal dissemination in gastric cancer.

Fluorescence-guided surgery (FGS) of cancer is an area of intense development. In the present report, we demonstrate that the telomerase-dependent green fluorescent protein (GFP)-containing adenovirus OBP-401 could label colon-cancer liver metastasis in situ in an orthotopic mouse model enabling successful FGS. OBP-401-GFP-labeled liver metastasis resulted in complete resection with FGS, in contrast, conventional bright-light surgery (BLS) did not result in complete resection of the metastasis. OBP-401-FGS reduced the recurrence rate and prolonged over-all survival compared with BLS. In conclusion, adenovirus OBP-401 is a powerful tool to label liver metastasis in situ with GFP which enables its complete resection, not possible with conventional BLS.

Photodynamic therapy (PDT) is a minimally invasive antitumor therapy that eradicates tumor cells through a photosensitizer-mediated cytotoxic effect upon light irradiation. However, systemic administration of photosensitizer often makes it difficult to avoid a photosensitive adverse effect. The red fluorescent protein KillerRed generates reactive oxygen species (ROS) upon green light irradiation. Here, we show the therapeutic potential of a novel tumor-specific replicating photodynamic viral agent (TelomeKiller) constructed using the human telomerase reverse transcriptase (hTERT) promoter. We investigated the light-induced antitumor effect of TelomeKiller in several types of human cancer cell lines. Relative cell viability was investigated using an XTT assay. The in vivo antitumor effect was assessed using subcutaneous xenografted tumor and lymph node metastasis models. KillerRed accumulation resulted in ROS generation and apoptosis in light-irradiated cancer cells. Intratumoral injection of TelomeKiller efficiently delivered the KillerRed protein throughout the tumors and exhibited a long-lasting antitumor effect with repeated administration and light irradiation in mice. Moreover, intratumorally injected TelomeKiller could spread into the regional lymph node area and eliminate micrometastasis with limited-field laser irradiation. Our results suggest that KillerRed has great potential as a novel photosensitizer if delivered with a tumor-specific virus-mediated delivery system. TelomeKiller-based PDT is a promising antitumor strategy to efficiently eradicate tumor cells. (C) 2015 AACR.

BACKGROUND: The purpose of this study is to determine the effects of anti-high mobility group box 1 (HMGB1) monoclonal antibody (mAb) on ischemia/reperfusion injury (IRI) and the mode of liver regeneration.
METHODS: Rats underwent 70% hepatectomy with IRI caused by clamping the hepatoduodenal ligament for 20 minutes, followed by the administration of anti-HMGB1 mAb immediately before declamping the hepatoduodenal ligament. Five animals were used for each time point. We then evaluated IRI, regeneration parameters and the status of HMGB1 in remnant livers.
RESULTS: The anti-HMGB1 mAb significantly ameliorated the degree of IRI in the remnant livers in association with the downregulation of HMGB1 protein. The ratio of Ki67-positive hepatocytes at 48 hours after 70% hepatectomy was significantly improved. Mean hepatocyte size was significantly reduced and cyclin-dependent kinase inhibitor 1 expression was significantly attenuated.
CONCLUSIONS: Anti-HMGB1 mAb ameliorated IRI and improved the mode of liver regeneration after IRI followed by 70% hepatectomy in rats. (C) 2016 Elsevier Inc. All rights reserved.

Human hepatocellular carcinoma (HCC) is known to have a poor prognosis. Sorafenib, a molecular targeted drug, is most commonly used for HCC treatment. However, its effect on HCC is limited in clinical use and therefore new strategies regarding sorafenib treatment are required. Iron overload is known to be associated with progression of chronic hepatitis and increased risk of HCC. We previously reported that iron depletion inhibited cancer cell proliferation and conversely induced angiogenesis. Indeed iron depletion therapy including iron chelator needs to be combined with anti-angiogenic drug for its anti-cancer effect. Since sorafenib has an anti-angiogenic effect by its inhibitory targeting VEGFR, we hypothesized that sorafenib could complement the anti-cancer effect of iron depletion. We retrospectively analyzed the relationship between the efficacy of sorafenib and serum iron-related markers in clinical HCC patients. In clinical cases, overall survival was prolonged in total iron binding capacity (TIBC) high- and ferritin low-patients. This result suggested that the low iron-pooled patients, who could have a potential of more angiogenic properties in/around HCC tumors, could be adequate for sorafenib treatment. We determined the effect of sorafenib (Nexavar (R)) and/or deferasirox (EXJADE (R)) on cancer cell viability, and on cell signaling of human hepatocarcinoma HepG2 and HLE cells. Both iron depletion by deferasirox and sorafenib revealed insufficient cytotoxic effect by each monotherapy, however, on the basis of increased angiogenesis by iron depletion, the addition of deferasirox enhanced anti-proliferative effect of sorafenib. Deferasirox was confirmed to increase vascular endothelial growth factor (VEGF) secretion into cellular supernatants by ELISA analysis. In in vivo study sorafenib combined with deferasirox also enhanced sorafenib-induced apoptosis. These results suggested that sorafenib combined with deferasirox could be a novel combination chemotherapy for HCC.

A 36-year-old Japanese man known to have incomplete Behçet's disease (oral aphthous ulcers, genital ulcers, skin lesions, and esophageal and ileocecal ulcers) was admitted to our hospital in January 2011 for abdominal pain. We administered corticosteroids and immunosuppressants. Two months later, we performed an ileocecal resection to control gastrointestinal bleeding from the ileocecal ulcers. High fever persisted after this surgery, and upper gastrointestinal endoscopy demonstrated ulcer penetration between the lower and abdominal esophagus. Eighteen days after the initial ileocecal resection, we performed a lower esophagus resection, gastric tube reconstruction and enterostomy, during which we confirmed a 5-mm-dia. perforated site at the posterior wall of the abdominal esophagus. Postoperative anastomotic leakage and empyema occurred, but they were relieved by thoracic drainage and empyema dissection.

記述言語：英語出版者・発行元：TAYLOR & FRANCIS INC

Although current immunosuppression protocols improve the efficacy of clinical allogenic islet transplantation, T cell-mediated allorejection remains unresolved, and major histocompatibility complexes (MHCs) play a crucial role in this process. Papain, a cysteine protease, has the unique ability to cleave the extracellular domain of the MHC class I structure. We hypothesized that pretreatment of donor islets with papain would diminish the expression of MHC class I on islets, reducing allograft immunogenicity and contributing to prolongation of islet allograft survival. BALB/c islets pretreated with papain were transplanted into C57BL/6J mice as an acute allorejection model. Treatment with 1mg/mL papain significantly prolonged islet allograft survival. In vitro, to determine the inhibitory effect on T cell-mediated alloreactions, we performed lymphocyte proliferation assays and mixed lymphocyte reactions. Host T cell activation against allogenic islet cells was remarkably suppressed by pretreatment of donor islet cells with 10mg/mL papain. Flow cytometric analysis was also performed to investigate the effect of papain treatment on the expression of MHC class I on islets. One or 10mg/mL papain treatment reduced MHC class I expression on the islet cell surface. Pretreatment of donor islets with papain suppresses MHC class I-mediated allograft rejection in mice and contributes to prolongation of islet allograft survival without administration of systemic immunosuppressants. These results suggest that pretreatment of human donor islets with papain may reduce the immunogenicity of the donor islets and minimize the dosage of systemic immunosuppressants required in a clinical setting.

記述言語：英語出版者・発行元：TAYLOR & FRANCIS INC

We previously reported real-time monitoring of cell cycle dynamics of cancer cells throughout a live tumor intravitally using a fluorescence ubiquitination cell cycle indicator (FUCCI). Approximately 90% of cancer cells in the center and 80% of total cells of an established tumor are in G(0)/G(1) phase. Longitudinal real-time FUCCI imaging demonstrated that cytotoxic agents killed only proliferating cancer cells at the surface and, in contrast, and had little effect on the quiescent cancer cells. Resistant quiescent cancer cells restarted cycling after the cessation of chemotherapy. Thus cytotoxic chemotherapy which targets cells in S/G(2)/M, is mostly ineffective on solid tumors, but causes toxic side effects on tissues with high fractions of cycling cells, such as hair follicles, bone marrow and the intestinal lining. We have termed this phenomenon tumor intrinsic chemoresistance (TIC). We previously demonstrated that tumor-targeting Salmonella typhimurium A1-R (S. typhimurium A1-R) decoyed quiescent cancer cells in tumors to cycle from G(0)/G(1) to S/G(2)/M demonstrated by FUCCI imaging. We have also previously shown that when cancer cells were treated with recombinant methioninase (rMETase), the cancer cells were selectively trapped in S/G(2), shown by cell sorting as well as by FUCCI. In the present study, we show that sequential treatment of FUCCI-expressing stomach cancer MKN45 in vivo with S. typhimurium A1-R to decoy quiescent cancer cells to cycle, with subsequent rMETase to selectively trap the decoyed cancer cells in S/G(2) phase, followed by cisplatinum (CDDP) or paclitaxel (PTX) chemotherapy to kill the decoyed and trapped cancer cells completely prevented or regressed tumor growth. These results demonstrate the effectiveness of the praradigm of decoy, trap and shoot chemotherapy.

Background: Pancreatico-biliary malignancies exhibit similar characteristics, including obesity-related features and poor prognosis, and require new treatment strategies. Oxidative stress is known to induce DNA damage and carcinogenesis, and its reduction is viewed as being favorable. However, it also has anti-infection and anti-cancer functions that need to be maintained. To reveal the effect of oxidative stress on cancer progression, we evaluated oxidative stress and anti-oxidative balance in pancreatic cancer (PC) and cholangiocarcinoma (CC) patients, as well as the effect of add-on antioxidant treatment to chemotherapy in a mouse cholangiocarcinoma model.
Methods: We recruited 84 CC and 80 PC patients who were admitted to our hospital. Serum levels of reactive oxygen metabolites (ROM) and the anti-oxidative OXY-adsorbent test were determined and the balance of these tests was defined as an oxidative index. A diabetic mouse-based cholangiocarcinoma model was utilized to evaluate the effects of add-on antioxidant therapy on cholangiocarcinoma chemotherapy.
Results: Serum ROM was higher and anti-oxidant OXY was lower in CC patients with poor outcomes. These parameters were not significantly different in PC patients. In mice, vitamin E administration induced antioxidant hemeoxygenase (HO)-1 protein expression in cancer tissue, while the number of stem-like cells increased. L-carnitine administration improved intestinal microbiome and biliary acid balance, upregulated the hepatic mitochondrial membrane uptake related gene Cpt1 in non-cancerous tissue, and did not alter stem-like cell numbers.
Conclusion: Oxidative stress balance was dysregulated in cholangiocarcinoma with poor outcome. The mitochondrial function-supporting agent L-carnitine is a good candidate to control oxidative stress conditions.

The patient was a 46-year old Japanese female who had undergone wide excision of the iliac bone and hip transposition at our institute's orthopedics department 2 years earlier. She presented with a growing incisional hernia and was transferred to our gastroenterological surgery department for surgical treatment. We planned a mesh repair for the incisional hernia, which protruded over the right iliac bone. The dimensions of the abdominal defect were 15×9 cm, and we used prolene mesh to repair the defect. The mesh was fixed at the inner part of the iliac bone, folded back at the iliac horn and fixed to the abdominal oblique muscles. The postoperative course was smooth, and recurrence was not seen at 3.5 years after the operation. An incisional hernia as seen in this patient's case is very rare, but we found that the underlay technique and prolene mesh were very useful for the three-dimensional hernia repair.

The aim of this single-institution, retrospective, observational case-control study was to evaluate the safety and feasibility of laparoscopic proctocolectomy (PC) for ulcerative colitis (VC), by comparing it with a case-control series of open PC. Twenty UC patients who underwent laparoscopic PC were retrospectively compared with the open PC group of 12 patients matched for age, sex, and urgency of the operation. In the laparoscopic PC group, the operative time was significantly longer, but the amount of blood loss was significantly smaller. The open PC patients underwent an intraoperative blood transfusion significantly more often, and the serum C-reactive protein level on the first postoperative day was significantly higher in the open PC group. In the laparoscopic PC group, the rate of severe postoperative morbidities, grades 3 and 4 on the Clavien-Dindo classification, was significantly lower, and the median length of hospital stay was significantly shorter. Laparoscopic PC for patients with UC showed superior perioperative outcomes to open PC, except for longer operative time.

Although in the neoadjuvant setting for estrogen receptor (ER)-positive breast cancers, chemotherapy or hormone therapy alone does not result in satisfactory tumor response, it is unknown whether concurrent chemo-endocrine therapy is superior to chemotherapy alone in clinical outcomes. We conducted a randomized phase II trial to test the responses of ER-positive patients to concurrent administration of chemo-endocrine therapy in the neoadjuvant setting. Women with stage ER-positive, invasive breast cancer (n=28) received paclitaxel followed by fluorouracil, epirubicin, cyclophosphamide (T-FEC) and were randomized to receive concurrent chemo-endocrine therapy consisting of goserelin administered subcutaneously for premenopausal women or an aromatase inhibitor for post-menopausal women. The primary endpoint was the pathological complete response (pCR) rate after neoadjuvant therapy. Twenty-eight patients were randomized. There were no significant differences in pCR rate between the concurrent group (12.5%; 2/16) and the chemotherapy alone group (8.3%; 1112). Tumor size after therapy was significantly reduced in the concurrent therapy group (p=0.035), but not in the chemotherapy-alone group (p=0.622). Neoadjuvant chemotherapy with concurrent hormone therapy provided no significant improvement in pCR rate in ER-positive breast cancers. These preliminary results should be followed up by further studies.

近年の分子細胞生化学の発展により、分子標的治療薬によって飛躍的に予後改善を認める癌腫もでてきている。また、bevacizumabの台頭にみられるように、がん微小環境を制御することでより抗腫瘍効果を上げる例もでてきており、新しい可能性を示唆している。癌とがん微小環境の相互作用については以前より多く報告されており、その中心的な役割を担っているのが癌関連線維芽細胞(cancer-associated fibroblasts:CAFs)といわれている。以前よりわれわれは、食道癌の進展におけるがん微小環境の強い関与を推測し、特にCAFの作用に注目し分子標的となり得るシグナルの解析を行ってきた。しかしながら、CAFの単一のシグナル阻害のみでは癌の治療においては不十分な可能性が考えられた。現在までに多くのCAF細胞におけるシグナルを標的とした治療法が提案されてきたが、未だ十分な結果を得ていない。光線免疫療法は、2011年にMitsunagaらにて発表された近赤外線光を用いた標的分子特異的癌治療である。われわれは、その細胞特異性に殺傷できるシステムに注目し、現在CAFそのものを制御すべくCAFに対する光線化学療法の開発、またその効果を検討している。今後検討結果を随時報告する予定である。(著者抄録)

CLINICAL EPIGENETICS 7 doi:10.1186/s13148-015-0096-y 2015年7月

記述言語：英語出版者・発行元：BIOMED CENTRAL LTD

Background: The gene expressions of netrin-1 dependence receptors, DCC and UNC5C, are frequently downregulated in many cancers. We hypothesized that downregulation of DCC and UNC5C has an important growth regulatory function in gastric tumorigenesis.
Results: In the present study, a series of genetic and epigenetic analyses for DCC and UNC5C were performed in a Japanese cohort of 98 sporadic gastric cancers and corresponding normal gastric mucosa specimens. Loss of heterozygosity (LOH) analyses and microsatellite instability (MSI) analysis was applied to determine chromosomal instability (CIN) and MSI phenotypes, respectively. More than 5 % methylation in the DCC and UNC5C promoters were found in 45 % (44/98) and 32 % (31/98) gastric cancers, respectively, and in 9 % (9/105) and 5 % (5/105) normal gastric mucosa, respectively. Overall, 70 % (58 of 83 informative cases) and 51 % (40 of 79 informative cases) of gastric cancers harbored either LOH or aberrant methylation in the DCC and UNC5C genes, respectively. In total, 77 % (51 of 66 informative cases) of gastric cancers showed cumulative defects in these two dependence receptors and were significantly associated with chromosomal instability. Both DCC and UNC5C were inactivated in 97 % of CIN-positive gastric cancers and in 55 % of CIN-negative gastric cancers.
Conclusions: Defect in netrin receptors is a common feature in gastric cancers. DCC alterations are apparent in the early stages, and UNC5C alterations escalate with the progression of the disease, suggesting that the cumulative alterations of netrin-1 receptors was a late event in gastric cancer progression and emphasizing the importance of this growth regulatory pathway in gastric carcinogenesis.

Background. Post orthotopic liver transplantation (OLT) viral hepatitis is an immunological condition where immune cells induce hepatitis during conditions of immune-suppression. The immune-regulatory programmed death-1 (PD-1)/PD-ligand 1 system is acknowledged to play important roles in immune-mediated diseases. However, the PD-1/PD-L2 interaction is not well characterized, with PD-L2 also exhibiting an immunostimulatory function. We hypothesized that this atypical molecule could affect the recurrence of post-OLT hepatitis. To test this hypothesis, we conducted immunohistochemical staining analysis and in vitro analysis of PD-L2. Methods. The expression of PD-L2 was evaluated in liver biopsy specimens from patients with chronic hepatitis B (n = 15), post-OLT hepatitis B (n = 8), chronic hepatitis C (n = 48), and post-OLT hepatitis C (CH-C-OLT) (n = 14). The effect of calcineurin inhibitors (CNIs) and hepatitis C virus (HCV) on PD-L2 expression was investigated in hepatoma cell lines. Results. The PD-L2 was highly expressed on CH-C-OLT hepatocytes. Treatment of hepatoma cell lines with CNIs resulted in increased PD-L2 expression, especially in combination with HCV core or NS3 protein. Transfection of cell lines with PD-L2 containing plasmid resulted in high intercellular adhesion molecule-1 (ICAM-1) expression, which might enhance hepatitis activity. Conclusions. The PD-L2 is highly expressed on CH-C-OLT hepatocytes, whereas HCV proteins, in combination with CNIs, induce high expression of PD-L2 resulting in elevated expression of ICAM-1. These findings demonstrate the effect of CNIs on inducing PD-L2 and subsequent ICAM-1 expression, effects that may produce inflammatory cell infiltration in post-OLT hepatitis C.

Fluorescence-guided surgery (FGS) of cancer is an area of intense current interest. However, although benefits have been demonstrated with FGS, curative strategies need to be developed. Glioblastoma multiforme (GBM) is one of the most invasive of cancers and is not totally resectable using standard bright-light surgery (BLS) or current FGS strategies. We report here a curative strategy for FGS of GBM. In this study, telomerase-dependent adenovirus OBP-401 infection brightly and selectively labeled GBM with green fluorescent protein (GFP) for FGS in orthotopic nude mouse models. OBP-401-based FGS enabled curative resection of GBM without recurrence for at least 150 days, compared to less than 30 days with BLS.

Precise fluorescence-guided surgery (FGS) for pancreatic canter has the potential to greatly improve the outcome in this recalcitrant disease. To achieve this goal, we have used genetic reporters to-color code cancer and stroma cells in a patient-derived orthotopic xenograft (PDOX) model. The telomerase-dependent green fluorescent protein (GFP)-containing adenovirus OBP-401 was used to label the cancer cells of a pancreatic cancer PDOX. The PDOX was previously grown in a red fluorescent protein (RFP) transgenic Mouse that stably labeled the PDOX stroma cells bright red. The color-coded PDOX Model enabled FGS to to completely resect the pancreatic tumors including stroma. Dual-colored FGS significantly prevented local recurrence; which bright-light surgery or single-color FGS could not. FGS, with color-coded canter and stroma cells has important potential for improving the outcome of recalcitrant-cancer surgery.

A chyle leak can occur as a complication after neck or chest surgery. Such a leak prolongs the hospital stay and is sometimes life-threatening. The treatment options are conservative management, interventional radiologic embolization, and surgery. Thoracoscopic ligation of the thoracic duct has emerged as a promising and definitive treatment The case of a 65-year-old Japanese male patient with a rare congenital right aortic arch (type IIIB1 of Edward's classification) and a severe chyle leak that occurred after a total pharyngolaryngo-esophagectomy (TPLE) is described. The chyle leak was successfully managed by thoracoscopic ligation of the thoracic duct via a left-side approach with the patient in the prone position.

記述言語：英語出版者・発行元：TAYLOR & FRANCIS INC

The present study analyzed the heterogeneous cell-cycle dependence and fate of single cancer cells in a population treated with UVB using a fluorescence ubiquitination-based cell-cycle (FUCCI) imaging system. HeLa cells expressing FUCCI were irradiated by 100 or 200 J/m(2) UVB. Modulation of the cell-cycle and apoptosis were observed by time-lapse confocal microscopy imaging every 30min for 72h. Correlation between cell survival and factors including cell-cycle phase at the time of the irradiation of UVB, mitosis and the G(1)/S transition were analyzed using the Kaplan-Meier method along with the log rank test. Time-lapse FUCCI imaging of HeLa cells demonstrated that UVB irradiation induced cell-cycle arrest in S/G(2)/M phase in the majority of the cells. The cells irradiated by 100 or 200 J/m(2) UVB during G(0)/G(1) phase had a higher survival rate than the cells irradiated during S/G(2)/M phase. A minority of cells could escape S/G(2)/M arrest and undergo mitosis which significantly correlated with decreased survival of the cells. In contrast, G(1)/S transition significantly correlated with increased survival of the cells after UVB irradiation. UVB at 200 J/m(2) resulted in a greater number of apoptotic cells.

PLOS ONE 10 ( 6 ) e0130409 2015年6月

記述言語：英語出版者・発行元：PUBLIC LIBRARY SCIENCE

Background
To improve the outcome of patients suffering from gastric cancer, a better understanding of underlying genetic and epigenetic events in this malignancy is required. Although CpG island methylator phenotype (CIMP) and microsatellite instability (MSI) have been shown to play pivotal roles in gastric cancer pathogenesis, the clinical significance of these events on survival outcomes in patients with gastric cancer remains unknown.
Methods
This study included a patient cohort with pathologically confirmed gastric cancer who had surgical resections. A cohort of 68 gastric cancers was analyzed. CIMP and MSI statuses were determined by analyzing promoter CpG island methylation status of 28 genes/loci, and genomic instability at 10 microsatellite markers, respectively. A Cox's proportional hazards model was performed for multivariate analysis including age, stage, tumor differentiation, KRAS mutation status, and combined CIMP/MLH1methylation status in relation to overall survival (OS).
Results
By multivariate analysis, longer OS was significantly correlated with lower pathologic stage (P = 0.0088), better tumor differentiation (P = 0.0267) and CIMP-high and MLH1 3' methylated status (P = 0.0312). Stratification of CIMP status with regards to MLH1 methylation status further enabled prediction of gastric cancer prognosis.
Conclusions
CIMP and/or MLH1 methylation status may have a potential to be prognostic biomarkers for patients with gastric cancer.

Fluorescence-guided surgery (FGS) of cancer is an area of intense interest. However, FGS of cancer has not yet been shown to be curative due to residual microscopic disease. Human fibrosarcoma HT1080 expressing red fluorescent protein (RFP) was implanted orthotopically in the quadriceps femoris muscle of nude mice. The tumor-bearing mice were injected with high and low-dose telomerase-dependent, green fluorescent protein (GFP)-containing adenovirus OBP-401, which labeled the tumor with GFP. Fluorescence-guided surgery (FGS) or bright light surgery (BLS) was then performed. OBP-401 could label soft-tissue sarcoma (STS) with GFP in situ, concordant with RFP. OBP-401-based FGS resulted in superior resection of STS in the orthotopic model of soft-tissue sarcoma, compared to BLS. High-dose administration of OBP-401 enabled FGS without residual sarcoma cells or local or metastatic recurrence, due to its dual effect of cancer-cell labeling with GFP and killing. High-dose OBP-401 based-FGS improved disease free survival (p = 0.00049) as well as preserved muscle function compared with BLS. High-dose OBP-401-based FGS could cure STS, a presently incurable disease. Since the parent virus of OBP-401, OBP-301, has been previously proven safe in a Phase I clinical trial, it is expected the OBP-401-FGS technology described in the present report should be translatable to the clinic in the near future.

MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally suppress the expression of many target genes, thereby contributing to the modulation of diverse cellular fates in tumor biology. Recent accumulating evidences have demonstrated that aberrant expression of miRNAs is highly associated with tumor initiation, progression and metastasis in various types of cancers including gastrointestinal (GI) cancers. Exploration of precise miRNA-based gene regulatory networks in the pathogenesis of GI cancers will provide important information for the development of novel anticancer strategies aimed at normalizing the critical miRNAs that are deregulated in GI cancers. Recent reports using clinical samples have shown the potential of upregulation of oncogenic miR-21 and of downregulation of the tumor-suppressive miR-34 family as novel molecular biomarkers for the diagnostic and prognostic prediction of GI cancers. In this review, we have focused on the functional roles of these two cancer-related miRNAs, miR-21 and miR-34, that are commonly deregulated during the development and progression of GI cancers. Moreover, the therapeutic potential of miRNA-targeting anticancer therapy is discussed for clinical application as novel anticancer therapy for GI cancers.

A case of advanced rectal cancer treated by aggressive local and systemic treatment who has survived more than 7 years from initial recurrence is presented. A 55-year-old woman was diagnosed with advanced lower rectal cancer and underwent a low anterior resection with complete removal of all regional lymph nodes and total mesorectal excision. The tumor was diagnosed as a moderately differentiated adenocarcinoma, pStage IIIB (T3, N2a, M0). Twenty-six months after the initial surgery, local recurrence in the pelvis was detected by computed tomography, and total pelvic exenteration with distal sacrectomy (TPES) was performed after systemic chemotherapy with a molecular-targeted drug. Six months after the TPES, multiple lung metastases were detected. Consequently, the patient underwent radiofrequency ablation (RFA) and chemotherapy. The disease has since been controlled for 38 months. As volume control is essential for cancer treatment, it may be important to combine appropriate local therapy with systemic therapy to metastatic or recurrent sites in order to achieve much longer disease control.

Background Molecular-based companion diagnostic tests are being used with increasing frequency to predict their clinical response to various drugs, particularly for molecularly targeted drugs. However, invasive procedures are typically required to obtain tissues for this analysis. Circulating tumour cells (CTCs) are novel biomarkers that can be used for the prediction of disease progression and are also important surrogate sources of cancer cells. Because current CTC detection strategies mainly depend on epithelial cell-surface markers, the presence of heterogeneous populations of CTCs with epithelial and/or mesenchymal characteristics may pose obstacles to the detection of CTCs.
Methods We developed a new approach to capture live CTCs among millions of peripheral blood leukocytes using a green fluorescent protein (GFP)-expressing attenuated adenovirus, in which the telomerase promoter regulates viral replication (OBP-401, TelomeScan).
Results Our biological capturing system can image epithelial and mesenchymal tumour cells with telomerase activities as GFP-positive cells. After sorting, direct sequencing or mutation-specific PCR can precisely detect different mutations in KRAS, BRAF and KIT genes in epithelial, mesenchymal or epithelial-mesenchymal transition-induced CTCs, and in clinical blood samples from patients with colorectal cancer.
Conclusions This fluorescence virus-guided viable CTC capturing method provides a non-invasive alternative to tissue biopsy or surgical resection of primary tumours for companion diagnostics.

Background:/Aims: Pancreatic neuroendocrine tumors (PNET) are relatively rare. Here, we present clinical and pathological characteristics of PNETs to show a relationship between computed tomography (CT) imaging and the 2010 World Health Organization (WHO) classification. Methodology: We retrospectively reviewed the records of 41 PNET patients who were treated between 2002 and 2012. All tumors were classified as neuroendocrine tumor (NET) grade 1 (121), NET grade 2 (G2), or neuroendocrine carcinoma (NEC) grade 3 (G3) on the basis of the 2010 WHO classification system. Results: Twenty-five tumors were classified as G1, 11 as G2, and five as G3. Mean sizes of the G1, G2 and G3 tumors were 1.84 +/- 0.54, 4.90 +/- 0.84, and 5.62 +/- 1.18 cm, respectively, (P < 0.01). A PNET is typically hypervascular and exhibits contrast enhancement on enhanced CT. Higher percentage of G1 tumors demonstrated typical imaging and showed a significantly greater distinct mass compared with G2 and G3 tumors. Conclusions: Although PNET has many imaging features that appear on CT, G2 and G3 tumors often show atypical imaging features, particularly with large sizes and/or ill-defined features, when compared with G1 tumors. If a PNET has atypical imaging features, possibility of malignancy should be considered.

AIM: To analyze the mismatch repair (MMR) status and the ARID1A expression as well as their clinicopathological significance in gastric adenocarcinomas.
METHODS: We examined the expressions of MMR proteins and ARID1A by immunohistochemistry in consecutive 489 primary gastric adenocarcinomas. The results were further correlated with clinicopathological variables.
RESULTS: The loss of any MMR protein expression, indicative of MMR deficiency, was observed in 38 cases (7.8%) and was significantly associated with an older age (68.6 +/- 9.2 vs 60.4 +/- 11.7, P < 0.001), a female sex (55.3% vs 31.3%, P = 0.004), an antral location (44.7% vs 25.7%, P = 0.021), and a differentiated histology (57.9% vs 39.7%, P = 0.023). Abnormal ARID1A expression, including reduced or loss of ARID1A expression, was observed in 109 cases (22.3%) and was significantly correlated with lymphatic invasion (80.7% vs 69.5%, P = 0.022) and lymph node metastasis (83.5% vs 73.7%, P = 0.042). The tumors with abnormal ARID1A expression more frequently indicated MMR deficiency (47.4% vs 20.2%, P < 0.001). A multivariate analysis identified abnormal ARID1A expression as an independent poor prognostic factor (HR = 1.36, 95% CI: 1.01-1.84; P = 0.040).
CONCLUSION: Our observations suggest that the AIRD1A inactivation is associated with lymphatic invasion, lymph node metastasis, poor prognosis, and MMR deficiency in gastric adenocarcinomas.

The prognosis of HER2-positive breast cancer has been improved by trastuzumab therapy, which features high specificity and limited side effects. However, trastuzumab-based therapy has shortcomings. Firstly, HER2-targeted therapy is only applicable to HER2-expressing tumors, which comprise only 20-25 % of primary breast cancers. Secondly, many patients who initially respond to trastuzumab ultimately develop disease progression. To overcome these problems, we employed virus-mediated HER2 transduction and photoimmunotherapy (PIT) which involves trastuzumab conjugated with a photosensitizer, trastuzumab-IR700, and irradiation of near-infrared light. We hypothesized that the gene transduction technique together with PIT would expand the range of tumor entities suitable for trastuzumab-based therapy and improve its antitumor activity. The HER2-extracellular domain (ECD) was transduced by the adenoviral vector, Ad-HER2-ECD, and PIT with trastuzumab-IR700 was applied in the HER2-negative cancer cells. Ad-HER2-ECD can efficiently transduce HER2-ECD into HER2-negative human cancer cells. PIT with trastuzumab-IR700 induced direct cell membrane destruction of Ad-HER2-ECD-transduced HER2-negative cancer cells. Novel combination of viral transduction of a target antigen and an antibody-based PIT would expand and potentiate molecular-targeted therapy even for target-negative or attenuated cancer cells.

Mediastinal lymph node metastasis from colorectal cancer is rare, and barely any reports have described resection of this pathology. We report herein a successful thoracoscopic resection of mediastinal lymph node metastasis in a prone position. A 65-year-old man presented with posterior mediastinal lymph node metastasis after resection of the primary rectal cancer and metachronous hepatic metastasis. Metastatic lymph nodes were resected completely using thoracoscopic surgery in the prone position, which provided advantages of minimal invasiveness, good surgical field, and reduced ergonomic burden on the surgeon. Thoracoscopic resection in the prone position was thought to have the potential to become the standard procedure of posterior mediastinal tumors.

Essentially every population of cancer cells within a tumor is heterogeneous, especially with regard to chemosensitivity and resistance. In the present study, we utilized the fluorescence ubiquitination-based cell cycle indicator (FUCCI) imaging system to investigate the correlation between cell-cycle behavior and apoptosis after treatment of cancer cells with chemotherapeutic drugs. HeLa cells expressing FUCCI were treated with doxorubicin (DOX) (5M) or cisplatinum (CDDP) (5M) for 3h. Cell-cycle progression and apoptosis were monitored by time-lapse FUCCI imaging for 72h. Time-lapse FUCCI imaging demonstrated that both DOX and CDDP could induce cell cycle arrest in S/G(2)/M in almost all the cells, but a subpopulation of the cells could escape the block and undergo mitosis. The subpopulation which went through mitosis subsequently underwent apoptosis, while the cells arrested in S/G(2)/M survived. The present results demonstrate that chemoresistant cells can be readily identified in a heterogeneous population of cancer cells by S/G(2)/M arrest, which can serve in future studies as a visible target for novel agents that kill cell-cycle-arrested cells.

Esophageal reconstruction using intestine is often performed for esophageal cancer patients in cases where the stomach cannot be used. We have previously performed reconstruction using ileocolon with supercharge and drainage as our first choice in those cases. However, a less invasive, simpler, and safer reconstructive technique using jejunum without vascular anastomosis has recently become popular at our facility. This study describes the technique of esophageal reconstruction with jejunum, compares the surgical outcomes to those of standard reconstruction using ileocolon, and discusses the clinical significance of this new concept.
Subjects comprised 53 patients (52 males, 1 female) who underwent esophageal reconstruction using jejunum between January 2008 and July 2013. Patient characteristics, technical details, and outcomes were compared with those of 51 subjects who had undergone esophageal reconstruction using ileocolon. When making the pedicled jejunal flap, the first jejunal vascular arcade was preserved, which in most cases allowed it to be pulled up to the cervical region by processing and transection up to the second jejunal vascular branch.
The vascular anastomosis techniques were used in 80.4 % (41/51) of esophageal reconstructions using colon, compared with only 24.5 % (13/53) of reconstructions using jejunum. No difference in the frequency of postoperative adverse effects was seen between groups, but the frequency of diarrhea was significantly lower with reconstruction using jejunum.
Esophageal reconstruction using jejunum with the blood vessel processing technique results in both simpler and safer pulling up. Thus the need to perform supercharge and superdrainage is reduced.

Pancreatic lymphoepithelial cysts (LECs) are rare benign pancreatic cystic lesions, the etiology of which is unknown. We report a case of a pancreatic LEC, discovered incidentally in a 63-year-old man during a follow-up clinic visit for an abdominal aneurysm. Computed tomography showed a multilocular cyst, 60-mm diameter in the body of the pancreas. This cyst increased from 6.0 to 6.5 cm during 12 months of observation. Part of the cyst was also visualized on positron emission tomography imaging. Since a pancreatic cystic neoplasm could not be ruled out, we performed distal pancreatectomy and postoperative pathological examination confirmed that the lesion was an LEC of the pancreas. Despite the conclusive postoperative findings, resection is unavoidable when a true pancreatic neoplasm cannot be excluded.

記述言語：英語出版者・発行元：Bentham Science Publishers B.V.

A multidisciplinary approach of combining surgery, chemotherapy and radiotherapy has remained the accepted standard management for various types of human cancer. However, many new treatment options have recently become available, including molecular targeted therapies, immunotherapies and oncolytic virotherapies. Replication-selective tu-mor-specific viruses have been designed to induce virus-mediated lysis of tumor cells after selective viral propagation within the tumor. We constructed an attenuated adenovirus 5 vector, telomelysin (OBP-301), in which the telomerase-specific promoter drives expression of viral replication-inducible E1 genes. Although telomelysin alone exhibited substantial antitumor effects both in animal models and in clinical trials, telomelysin has the potential to be the first-in-class oncolytic virus for combination therapy based on our current understanding of the molecular mechanisms. Telomelysin sensitizes human cancer cells to ionizing radiation by inhibiting the radiation-induced DNA repair machinery, and also eliminates radio-resistant quiescent cancer stem-like cells by promoting cell cycle entry. A clinical trial of intratumoral administration of telomelysin with radiotherapy in esophageal cancer patients is currently underway. This article reviews recent highlights in the rapidly evolving field of multidisciplinary therapy with telomelysin.

Background: Current methods of image-guided surgery of tumours of the lung mostly rely on CT. A sensitive procedure of selective tumour fluorescence labelling would allow simple and high-resolution visualisation of the tumour for precise surgical navigation. Methods: Human lung cancer cell lines H460 and A549 were genetically transformed to express red fluorescent protein (RFP). Tumours were grown subcutaneously for each cell line and harvested and minced for surgical orthotopic implantation on the left lung of nude mice. Tumour growth was measured by fluorescence imaging. After the tumours reached 5 mm in diameter, they were injected under fluorescence guidance with the telomerase-dependent green fluorescent protein (GFP)-containing adenovirus, OBP-401. Viral labelling of the lung tumours with GFP precisely colocalised with tumour RFP expression. Three days after administration of OBP-401, fluorescence-guided surgery (FGS) was performed. Results: FGS of tumours in the lung was enabled by labelling with a telomerase-dependent adenovirus containing the GFP gene. Tumours in the lung were selectively and brightly labelled. FGS enabled complete lung tumour resection with no residual fluorescent tumour. Conclusions: FGS of tumours in the lung is feasible and more effective than bright-light surgery.

Objective Hepatopulmonary syndrome (HPS) is characterized by vascular dilatation and hyperdynamic circulation, while portopulmonary hypertension (POPH) is characterized by vasoconstriction with fibrous obliteration of the vascular bed. Vasoactive molecules such as nitric oxide (NO) are candidate factors for cirrhotic complications associated with these diseases. However, oxidative stress balance is not well characterized in HPS and POPH. The present objective is to investigate the oxidative stress and anti-oxidative stress balance and NO pathway balance in patients with potential HPS and POPH.
Methods We recruited patients with decompensated cirrhosis (n = 69) admitted to our hospital as liver transplantation candidates. Patients exhibiting partial pressure of oxygen lower than 80 mmHg and alveolararterial oxygen gradient (AaDO(2)) >= 15 mmHg were categorized as potentially having HPS (23 of 69 patients). Patients exhibiting a tricuspid regurgitation pressure gradient >= 25 mmHg were categorized as potentially having POPH (29 of 61 patients). Serum reactive oxygen metabolites were measured and anti-oxidative OXY-adsorbent test (OXY) were performed, and the balance of these tests was defined as the oxidative index. The correlation between these values and the clinical characteristics of the patients were assessed in a cross-sectional study.
Results Potential HPS patients exhibited no correlation with oxidative stress markers. Potential POPH patients exhibited lower OXY (p = 0.037) and higher oxidative index values (p = 0.001). Additionally, the vascular NO synthase enzyme inhibiting protein, asymmetric dimethylarginine, was higher in potential POPH patients (p = 0.049). The potential POPH patients exhibited elevated AaDO(2), suggesting the presence of pulmonary shunting.
Conclusion Potential POPH patients exhibited elevated oxidative stress with decreased anti-oxidative function accompanied by inhibited NO production. Anti-oxidants represent a candidate treatment for potential POPH patients.

癌抑制遺伝子プロモーター領域のCpG island(CGI)に認められるメチル化異常は、当初、癌細胞だけに認められると考えられていたが、正常細胞にも頻度は少ないが認められることが報告されている。そのような癌特異的(と考えられた)DNAメチル化異常を大腸癌早期発見のためのエピジェネティックバイオマーカーに設定した場合、偽陽性率を上昇させることが示唆される。しかし、これらの現象は、注意深く検証していけば、大腸癌の進行度を推測する強力なマーカーに成りうる場合もある。本稿では、大腸癌スクリーニングの現状を概説し、便潜血反応検査(FOBT)を含めて、便から遺伝子変異を検出する方法の歴史的経過を概説したのちに、メチル化DNA検出による大腸癌スクリーニングの可能性について考察する。(著者抄録)

Quiescent cancer cells are resistant to cytotoxic agents which target only proliferating cancer cells. Time-lapse imaging demonstrated that tumor-targeting Salmonella typhimurium A1-R (A1-R) decoyed cancer cells in monolayer culture and in tumor spheres to cycle from G(0)/G(1) to S/G(2)/M, as demonstrated by fluorescence ubiquitination-based cell cycle indicator (FUCCI) imaging. A1-R infection of FUCCI-expressing subcutaneous tumors growing in nude mice also decoyed quiescent cancer cells, which were the majority of the cells in the tumors, to cycle from G(0)/G(1) to S/G(2)/M, thereby making them sensitive to cytotoxic agents. The combination of A1-R and cisplatinum or paclitaxel reduced tumor size compared with A1-R monotherapy or cisplatinum or paclitaxel alone. The results of this study demonstrate that A1-R can decoy quiescent cancer cells to cycle to S/G(2)/M and sensitize them to cytotoxic chemotherapy. These results suggest a new paradigm of bacterial-decoy chemotherapy of cancer.

Orthotopic models of various types of tumors are widely used in anti-tumor therapeutic experiments in preclinical studies. However, there are few ways to appropriately monitor therapeutic effect in orthotopic tumor models, especially for tumors invisible from the outside. In this study we aimed to establish a non-invasive semi-quantitative bioluminescent imaging method of monitoring an orthotopic esophageal cancer mouse model. We confirmed that the TE8 esophageal cancer cell line implanted orthotopically into the abdominal esophagus of nu/nu mice (n=5) developed not only a main tumor at the implanted site, but also local lymph node metastases and peritoneal disseminations within 6 weeks after inoculation. We established a TE8 cell line that stably expressed the firefly luciferase gene (TE8-Luc). We showed that TE8-Luc cells implanted subcutaneously into nu/nu mice (n=5) grew over time until 5 weeks after inoculation. Tumor volume was strongly correlated with luminescent intensity emitted from the tumor, which was quantified using the IVIS imaging system. We then showed that TE8-Luc cells implanted orthotopically into the mouse abdominal esophagus (n=8) also formed a tumor and that the luminescent intensity of such a tumor, as detected by IVIS, increased over time until 7 weeks after inoculation and was therefore likely to reflect tumor progression. We therefore propose that this orthotopic esophageal cancer model, monitored using the non-invasive semi-quantitative IVIS imaging system, will be useful for in vivo therapeutic experiments against esophageal cancer. This experimental setting is expected to contribute to the development of novel therapeutic technologies for esophageal cancer in preclinical studies.

To apply an individualized oncological approach to gastric cancer patients, the accurate diagnosis of disease entities is required. Peritoneal metastasis is the most frequent mode of metastasis in gastric cancer, and the tumor-node-metastasis classification includes cytological detection of intraperitoneal cancer cells as part of the staging process, denoting metastatic disease. The accuracy of cytological diagnosis leaves room for improvement; therefore, highly sensitive molecular diagnostics, such as an enzyme immunoassay, reverse transcription polymerase chain reaction, and virus-guided imaging, have been developed to detect minute cancer cells in the peritoneal cavity. Molecular targeting therapy has also been spun off from basic research in the past decade. Although conventional cytology is still the mainstay, novel approaches could serve as practical complementary diagnostics to cytology in near future. (C) 2014 Baishideng Publishing Group Inc.

Background/Aims: Hepatopancreatoduodenectomy (HPD) is performed to achieve radical resection of malignant biliary tumors. We reviewed clinical outcomes to evaluate the utility of HPD in terms of morbidity and mortality. Methodology: A retrospective analysis was conducted on 17 patients underwent HPD between August 1991 and May 2013; 9 bile duct cancel; 5 advanced gallbladder and 3pancreatic tumor with liver metastasis. Results: The morbidity and mortality rates were 88.3% and 0%, respectively. Univariate analysis showed that a body mass index of >= 22 and preoperative total bilirubin level >= 0.8 mg/dl were significantly associated with severe complications. One, 3- and 5-year survival rate were 73.3%, 60.0% and 30.0%. In 14 patients with biliary carcinoma, univariate analysis showed that a histological grade of G1 was significantly associated with survival. Patients without pancreatic invasion or portal vein invasion tended to survive longer than patients with these types of invasion, although the difference was not significant. Conclusions: HPD can be performed with no mortality and provides a survival benefit for some patients with biliary carcinoma undergoing curative resection. In patients with grade G1 biliary carcinoma without pancreatic or portal vein invasion in particular, this aggressive surgery might offer a chance of long-term survival.

It is not known how the immune system targets hepatitis C virus (HCV)-infected HLA-mismatched hepatocytes under immune-suppressed conditions after orthotopic liver transplantation (OLT). In addition, the relationship between the HCV-specific immune response and IL28B variants as predictors of HCV clearance has not been well-characterized. We determined the IL28B polymorphisms for 57 post-OLT HCV carriers, and we assessed the HCV-specific immune responses by measuring the peripheral blood mononuclear cell-derived HCV-specific interferon-gamma (IFN-gamma) response using an enzyme-linked immunospot assay. At 1-3 years after OLT, patients with no active hepatitis showed higher total spots on the immunospot assay. At > 3 years after OLT, patients with resolved HCV showed higher levels of core, NS3, NS5A, and total spots compared to the chronic hepatitis patients. The IL28B major genotype in the donors correlated with higher spot counts for NS5A and NS5B proteins at 1-3 years after OLT. In the post-OLT setting, the HCV-specific immune response could be strongly induced in patients with no active hepatitis with an IL28B major donor or sustained virological response. Strong immune responses in the patients with no active hepatitis could only be maintained for 3 years and diminished later. It may be beneficial to administer IFN treatment starting 3 years after OLT, to induce the maximum immunological effect.

Lynch syndrome is an autosomal dominant disease associated with a high incidence of colorectal, endometrial, stomach, ovarian, pancreatic, ureter and renal pelvis, bile duct and brain tumors. The syndrome can also include sebaceous gland adenomas and keratoacanthomas, and carcinoma of the small bowel. The lifetime risk for bile duct cancer in patients with Lynch syndrome is approximately 2 %. The present report describes a case of Lynch syndrome with metachronous bile duct cancer diagnosed at an early stage. The patient was a 73-year-old Japanese male who underwent a successful left lobectomy of the liver, and there was no sign of recurrence for 2 years postoperative. However, this patient harbored a germline mutation in MLH1, which prompted diagnostic examinations for noncolorectal tumors when a periodic surveillance blood examination showed abnormal values of hepatobiliary enzymes. Although most patients with bile duct cancer are diagnosed at an advanced stage, the bile duct cancer was diagnosed at an early stage in the present patient due to the observation of the gene mutation and the preceding liver tumor. This case illustrates the importance of continuous surveillance for extracolonic tumors, including bile duct cancer, in patients with Lynch syndrome.

A major impediment to the response of tumors to chemotherapy is that the large majority of cancer cells within a tumor are quiescent in G(0)/G(1), where cancer cells are resistant to chemotherapy. To attempt to solve this problem of quiescent cells in a tumor, cancer cells were treated with recombinant methioninase (rMETase), which selectively traps cancer cells in S/G(2). The cell cycle phase of the cancer cells was visualized with the fluorescence ubiquitination cell cycle indicator (FUCCI). At the time of rMETase-induced S/G(2)-phase blockage, identified by the cancer cells' green fluorescence by FUCCI imaging, the cancer cells were administered S/G(2)-dependent chemotherapy drugs, which interact with DNA or block DNA synthesis such as doxorubicin, cisplatin, or 5-fluorouracil. Treatment of cancer cells with drugs only, without rMETase-induced S/G(2) phase blockage, led to the majority of the cancer-cell population being blocked in G(0)/G(1) phase, identified by the cancer cells becoming red fluorescent in the FUCCI system. The G(0)/G(1) blocked cells were resistant to the chemotherapy. In contrast, trapping of cancer cells in S/G(2) phase by rMETase treatment followed by FUCCI-imaging-guided chemotherapy was highly effective in killing the cancer cells.

An intussusception due to colonic adenocarcinoma has sometimes been reported. However, to the best of our knowledge, reports of intussusception due to rectal adenocarcinoma are extremely rare. In this report, the case of a young man with rectal adenocarcinoma causing intussusception is described. A 24-year-old man visited a hospital complaining of abdominal pain, and an upper rectal cancer was diagnosed by colonoscopy. Computed tomography showed intussusception caused by a large tumor in the pelvis and absence of distant metastases. Locally advanced rectal cancer causing intussusception was diagnosed, and a low anterior resection was performed. Intraoperatively, repair of the invagination could not be accomplished easily; therefore, the repair was abandoned. Instead, the tumor was removed en bloc to avoid dissemination of the cancer. Histopathologically, the tumor was diagnosed as a poorly differentiated adenocarcinoma, pStage. A. The patient has no evidence of recurrence at 10 mo after the operation.

The phase of the cell cycle can determine whether a cancer cell can respond to a given drug. We report here on the results of monitoring of real-time cell cycle dynamics of cancer cells throughout a live tumor intravitally using a fluorescence ubiquitination cell cycle indicator (FUCCI) before, during, and after chemotherapy. In nascent tumors in nude mice, approximately 30% of the cells in the center of the tumor are in G(0)/G(1) and 70% in S/G(2)/M. In contrast, approximately 90% of cancer cells in the center and 80% of total cells of an established tumor are in G(0)/G(1) phase. Similarly, approximately 75% of cancer cells far from (>100 mu m) tumor blood vessels of an established tumor are in G(0)/G(1). Longitudinal real-time imaging demonstrated that cytotoxic agents killed only proliferating cancer cells at the surface and, in contrast, had little effect on quiescent cancer cells, which are the vast majority of an established tumor. Moreover, resistant quiescent cancer cells restarted cycling after the cessation of chemotherapy. Our results suggest why most drugs currently in clinical use, which target cancer cells in S/G(2)/M, are mostly ineffective on solid tumors. The results also suggest that drugs that target quiescent cancer cells are urgently needed.

Introduction: Regulatory T (Treg) and type 1 regulatory T (Tr1) cells facilitate hepatitis C virus (HCV) recurrence after orthotopic liver transplantation (OLT). However, their frequencies and effects on HCV-specific immune responses have not been well investigated.
Methods: We determined Treg and Tr1 frequencies in OLT patients with hepatitis C and assessed their associations with HCV-specific T cell responses. These patients comprised the following groups: an early post-transplantation group (n = 14); an OLT-chronic active hepatitis C group (n = 14) with active hepatitis C (alanine aminotransferase of > upper limit of normal/positive for HCV-RNA); an OLT-persistently normal alanine aminotransferase group (n = 12) without active hepatitis C (not interferon/positive for HCV-RNA); and an OLT-sustained viral response group (n = 6) with sustained viral responses using interferon treatment (negative for HCV-RNA). The frequencies of HCV-specific CD4+ T cells that secreted interferon-gamma were determined by enzyme-linked immunosorbent spot assay (except for the OLT early group).
Results: Treg and Tr1 frequencies were low during the early post-transplantation period. OLT patients with sustained viral responses had lower Treg frequencies than those with chronic hepatitis C, whereas Tr1 frequencies were significantly reduced in OLT patients with persistently normal alanine aminotransferase levels compared to those with chronic hepatitis C (p < 0.05). Treg frequencies positively correlated with HCV NS3 antigen-specific interferon-gamma responses, which corresponded to HCV clearance.
Conclusions: Increased Treg frequencies and reduced HCV-NS3 antigen-specific responses recovered after viral eradication in post-OLT chronic hepatitis C patients. Reduced Tr1 frequencies were associated with hepatitis activity control, which may facilitate controlling chronic hepatitis C in patients after OLT. (C) 2014 Elsevier B.V. All rights reserved.

Background: For cell therapies to treat diabetes, it is important to produce a sufficient number of pancreatic endocrine cells that function similarly to primary islets. Induced pluripotent stem (iPS) cells represent a potentially unlimited source of functional pancreatic endocrine cells. However, the use of iPS cells for laboratory studies and cell-based therapies is hampered by their high tumorigenic potential and limited ability to generate pure populations of differentiated cell types in vitro. The purpose of this study was to establish a pancreatic stem cell line from iPS cells derived from mouse fibroblasts.
Methods: Mouse iPS cells were induced to differentiate into insulin-producing cells by a multi-step differentiation protocol, which was conducted as described previously with minor modifications. Selection of the pancreatic stem cell was based on morphology and Pdx1 expression. The pancreatic potential of the pancreatic stem cells was evaluated using a reverse transcription PCR, real-time PCR, immunofluorescence, and a glucose challenge test. To assess potential tumorigenicity of the pancreatic stem cells, the cells were injected into the quadriceps femoris muscle of the left hindlimb of nude mice.
Results: The iPS-derived pancreatic stem cells expressed the transcription factor -Pdx1- a marker of pancreatic development, and continued to divide actively beyond passage 80. Endocrine cells derived from these pancreatic stem cells expressed insulin and pancreatic genes, and they released insulin in response to glucose stimulation. Mice injected with the pancreatic stem cells did not develop tumors, in contrast to mice injected with an equal number of iPS cells.
Conclusion: This strategy provides a new approach for generation of insulin-producing cells that is more efficient and safer than using iPS cells. We believe that this approach will help to develop a patient-specific cell transplantation therapy for diabetes in the near future.

Thoracoscopic esophagectomy in the prone position (TEPP) might enable solo-surgery in cases requiring resection of the esophagus and the surrounding lymph nodes due to the associated advantages of good exposure of the surgical field and ergonomic considerations for the surgeon. However, no one approach can be for all patients requiring extensive lymphadenectomy. We recently developed an assistant-based procedure to standardize exposure of the surgical field. Patients were divided into 1 of 2 groups: a pre-standardization group (n = 37) and a post-standardization group (n = 28). The thoracoscopic operative time was significantly shorter (p= 0.0037)) in the post-standardization group (n = 28; 267 +/- 31min) than in the pre-standardization group (n = 37; 301 +/- 53 min). Further, learning curve analysis using the moving average method showed stabilization of the thoracoscopic operative time after the standardization. No significant differences were found in the number of mediastinal lymph nodes dissected or intraoperative blood loss between the 2 groups. There were also no significant differences in the complication rate. Assistant-based surgery and standardization of the procedure resulted in a well-exposed and safe surgical field. TEPP decreased the operative time, even in patients requiring extensive lymphadenectomy.

Establishment of a preferential liver allocation rule for simultaneous liver and kidney transplantation (SLK) and revisions of laws regarding organ transplants from deceased donors have paved the way for SLK in Japan. Very few cases of SLK have been attempted in Japan, and no such recipients have survived for longer than 40 days. The present report describes a case of a 50-year-old woman who had undergone living donor liver transplantation at the age of 38 years for management of post-partum liver failure. After the first transplant surgery, she developed hepatic vein stenosis and severe hypersplenism requiring splenectomy. She was then initiated on hemodialysis (HD) due to the deterioration of renal function after insertion of a hepatic vein stent. She was listed as a candidate for SLK in 2011 because she required frequent plasma exchange for hepatic coma. When her Model for End-stage Liver Disease score reached 46, the new liver was donated 46 days after registration. The reduced trisegment liver and the kidney grafts were simultaneously transplanted under veno-venous bypass and intraoperative HD. The hepatic artery was reconstructed prior to portal reconstruction in order to shorten anhepatic time. Although she developed subcapsular bleeding caused by hepatic contusion on the next day, subsequent hemostasis was obtained by transcatheter embolization. Thereafter, her recovery was uneventful, except for mild rejection and renal tubular acidosis of the kidney graft. This case highlights the need to establish Japanese criteria for SLK.

Invasive cancer cells are a critical target in order to prevent metastasis. In the present report, we demonstrate real-time visualization of cell cycle kinetics of invading cancer cells in 3-dimensional (3D) Gelfoam (R) histoculture, which is in vivo-like. A fluorescence ubiquitination cell cycle indicator (FUCCI) whereby G(0)/G(1) cells express a red fluorescent protein and S/G(2)/M cells express a green fluorescent protein was used to determine the cell cycle position of invading and non-invading cells. With FUCCI 3D confocal imaging, we observed that cancer cells in G(0)/G(1) phase in Gelfoam (R) histoculture migrated more rapidly and further than cancer cells in S/G(2)/M phases. Cancer cells ceased migrating when they entered S/G(2)/M phases and restarted migrating after cell division when the cells re-entered G(0)/G(1). Migrating cancer cells also were resistant to cytotoxic chemotherapy, since they were preponderantly in G(0)/G(1), where cytotoxic chemotherapy is not effective. The results of the present report suggest that novel therapy targeting G(0)/G(1) cancer cells should be developed to prevent metastasis.

Background/Aims: PuraMatrix is a synthetic material consisting of 16-amino acid peptides that self-assemble into nanofibers, previously used as a scaffold for functional cell cultures. We conducted a clinical study to determine the safety and sealing properties of PuraMatrix in post-operative lymphorrhea following pelvic surgery in humans. Methodology: A total of 20 patients who underwent rectal cancer resection were analyzed. The study group (n = 10) consisted of patients who received PuraMatrix, matched with a control group (n = 10) of patients operated on conventionally. Results: During the 2 to 3 month follow-up period, there were no abnormal findings or adverse events in any the patients who received PuraMatrix. We found that the patients who received PuraMatrix had significantly reduced post-operative drainage volumes compared with the patients in the control group. Conclusions: PuraMatrix is a safe and effective bio-compatible sealing material for the management of post-operative peritoneal effusion following pelvic surgery.

We examined estrogen receptor (ER) mRNA expression and molecular subtypes in stage I-III breast cancers that are progesterone receptor (PR) positive but ER and HER2 negative by immunohistochemistry (IHC) or fluorescent in situ hybridization. The ER, PR, and HER2 status was determined by IHC as part of routine clinical assessment (N = 501). Gene expression profiling was done with the Affymetrix U133A gene chip. We compared expressions of ESR1 and MKI67 mRNA, distribution of molecular subtypes by the PAM50 classifier, the sensitivity to endocrine therapy index, and the DLDA30 chemotherapy response predictor signature among ER/PR-positive (n = 223), ER-positive/PR-negative (<Emphasis Type="ItalicUnderline">n = 73), ER-negative/PR-positive (n = 20), and triple-negative (n = 185) cancers. All patients received neoadjuvant chemotherapy with an anthracycline and taxane and had adjuvant endocrine therapy only if ER or PR > 10 % positive. ESR1 expression was high in 25 % of ER-negative/PR-positive, in 79 % of ER-positive/PR-negative, in 96 % of ER/PR-positive, and in 12 % of triple-negative cancers by IHC. The average MKI67 expression was significantly higher in the ER-negative/PR-positive and triple-negative cohorts. Among the ER-negative/PR-positive patients, 15 % were luminal A, 5 % were Luminal B, and 65 % were basal like. The relapse-free survival rate of ER-negative/PR-positive patients was equivalent to ER-positive cancers and better than the triple-negative cohort. Only 20-25 % of the ER-negative/PR-positive tumors show molecular features of ER-positive cancers. In this rare subset of patients (i) a second RNA-based assessment may help identifying the minority of ESR1 mRNA-positive, luminal-type cancers and (ii) the safest clinical approach may be to consider both adjuvant endocrine and chemotherapy.

We report the case of a 61-old-man with a primary malignant melanoma of the esophagus, an extremely rare and highly aggressive malignancy. He presented with dysphagia, and we performed an upper gastrointestinal endoscopy that detected a tumor in the thoracic part of the esophagus. The biopsy showed malignant melanoma. PET/CT, endoscopy and an esophagogram showed that a 70-mm scaled type 2+1 tumor in the thoracic esophagus and no metastases. We diagnosed a cT3cN0cM0 cStage II tumor. We then performed a subtotal esophagectomy with two-field lymph node dissection and esophagogastrostomy via a retrosternal route. The pathological examination of the resected specimens confirmed that the type 2+1 tumor was PMME (pT2N0M0 pStage II). We administered six courses of postoperative adjuvant chemotherapy with dacarbazine, and the patient has had no recurrence for 17 months after the surgery.

Background: A combination of hepatitis B immunoglobulin and nucleos(t)ide analogues is the current standard of care for controlling hepatitis B recurrence after orthotopic liver transplantation (OLT). However, frequent immunoglobulin treatment is expensive and inconvenient. This study investigated the efficacy of hepatitis B virus (HBV) vaccination in preventing the recurrence of hepatitis B after living donor OLT. Methods: Twenty-seven patients who had undergone living donor OLT participated in the study
five had acute HBV infected liver failure (ALF-OLT) and 22 had HBV related liver cirrhosis (LC-OLT). Hepatitis B surface antigen (HBsAg)-containing vaccine was administered to them for at least 1 year after transplantation and continued once monthly for up to 36 months post-OLT. Patients who had anti-HBs antibody titers above 100 mIU/mL for a minimum of 6 months without immunoglobulin administration were defined as good responders
the others were defined as poor responders. Interferon-γ enzyme-linked immunospot assays against HBs and HBc antigens were used to assay cellular immune responses. Results: All five of the ALF-OLT patients had good responses after a median of four (range 2.5-5) vaccinations. Nine of the 22 LC-OLT patients had good responses after a median of 19 (range 11.5-30) vaccinations. Among the LC-OLT group, those with livers donated by relatively higher-aged, marital and high-titer anti-HBs antibody donors were good responders. LC-OLT patients classed as good responders showed interferon-γ responses comparable to those of the ALF-OLT patients. Conclusions: The ALF-OLT and LC-OLT patients who received livers from relatively higher-aged, marital, high-titer anti-HBs antibody donors were the best candidates for HBV vaccine administration. Boosting donors before transplantation may facilitate later vaccine response of the recipients. © 2013 The Author(s).

記述言語：英語出版者・発行元：SPANDIDOS PUBL LTD

We evaluated the antitumor effect of a telomerase-specific replication-selective adenovirus (Telomelysin, OBP-301) for adenoid cystic carcinoma (ACC) in vitro and in vivo. Adenovirus E1 gene expression was controlled by human telomerase reverse transcription (hTERT). Infection of ACC cells by OBP-301 induced high E1A mRNA expression and subsequent oncolytic cell death in a dose-dependent manner. Using OBP-401 (TelomeScan), a genetically engineered adenovirus that carries the GFP gene under the control of the cytomegalovirus (CMV) promoter at the deleted E3 region of OBP-301, ACC cells expressed bright GFP fluorescence as early as 12 h after OBP-401 infection. The fluorescence intensity gradually increased in a time-dependent manner, followed by rapid cell death due to the cytopathic effect of OBP-401, as evidenced by the floating, highly light-refractive cells using phase-contrast microscopy. Effects of intratumorally injected OBP-401 against established Acc2 xenograft tumors were seen in BALB/c nu/nu mice. The levels of GFP expression following ex vivo infection of OBP-401 may be of value as a positive predictive marker for the outcome of telomerase-specific virotherapy. Our data clearly indicated that telomerase-specific oncolytic adenoviruses have significant therapeutic potential against human ACC in vitro and in vivo. These results suggest that treatment with OBP-301 and OBP-401 may improve the quality of life of oral cancer patients.

Background: Surgical site infection (SSI) is an ongoing major public health problem throughout the world that increases healthcare costs. Utilizing a methodology that can help clinicians to continuously collect data about SSIs, analyse it and implement the feedback into routine hospital practice has been identified as a top national priority in Japan.
Aim: To conduct an intervention study through 'operations research' using partitioning at multiple facilities, and to reduce the incidence and consequences of SSI.
Methods: The Setouchi SSI Surveillance Group, which consists of seven institutes, started SSI surveillance in 2006. Until May of 2008, there were four surveillance periods (A-D). In all, 3089 patients underwent gastrointestinal surgery and were followed up for 30 days after their operations. Twenty-six factors that have been reported to be related to SSI were evaluated for all patients. The top three factors from each surveillance period were determined and then actual practice improvements were planned for each subsequent period.
Findings: The total SSI occurrence was 6.9% for period A, 6.3% for period B, 6.4% for period C and 3.9% for period D. Comparing periods A and D, there was a statistical significance in the decrease of SSI occurrence (P = 0.012).
Conclusion: Using the results and partitioning analysis of active SSI surveillance to contribute to action plans for improving clinical practice was effective in significantly reducing SSIs. (C) 2013 The Healthcare Infection Society. Published by Elsevier Ltd. All rights reserved.

記述言語：英語

We present a case in which combination chemotherapy was used to successfully treat hepatocellular carcinoma (HCC) with rapid progression of lymph node (LN) metastases after liver resection. In addition, epithelial to mesenchymal transition (EMT) markers were examined immunohistochemically. A 43-year-old man who had been diagnosed with HCC showed an enlarged LN near the hepatic artery proper. After extended left lobectomy with lymphadenectomy in the hepatoduodenal ligament, he experienced rapid progression of metastases to the para-aortic and mediastinal LN. Partial remission was achieved after induction and maintenance of combination chemotherapy using etoposide, carboplatin, epirubicin and 5-fluorouracil. As a consequence of this treatment, the patient survived 10 months. Immunohistochemical studies demonstrated that HCC cells in the metastatic LN showed low expression of E-cadherin and high expression of N-cadherin and vimentin, indicating EMT. Combination chemotherapy may prove effective for patients with HCC accompanied by LN metastases that show features of EMT.

Purpose: Because chemoradiotherapy selectively targets proliferating cancer cells, quiescent cancer stem-like cells are resistant. Mobilization of the cell cycle in quiescent leukemia stem cells sensitizes them to cell death signals. However, it is unclear that mobilization of the cell cycle can eliminate quiescent cancer stem-like cells in solid cancers. Thus, we explored the use of a genetically-engineered telomerase-specific oncolytic adenovirus, OBP-301, to mobilize the cell cycle and kill quiescent cancer stem-like cells.
Experimental Design: We established CD133(+) cancer stem-like cells from human gastric cancer MKN45 and MKN7 cells. We investigated the efficacy of OBP-301 against quiescent cancer stem-like cells. We visualized the treatment dynamics of OBP-301 killing of quiescent cancer stem-like cells in dormant tumor spheres and xenografts using a fluorescent ubiquitination cell-cycle indicator (FUCCI).
Results: CD133(+) gastric cancer cells had stemness properties. OBP-301 efficiently killed CD133(+) cancer stem-like cells resistant to chemoradiotherapy. OBP-301 induced cell-cycle mobilization from G(0)-G(1) to S/G(2)/M phases and subsequent cell death in quiescent CD133(+) cancer stem-like cells by mobilizing cell-cycle-related proteins. FUCCI enabled visualization of quiescent CD133(+) cancer stem-like cells and proliferating CD133(-) non-cancer stem-like cells. Three-dimensional visualization of the cell-cycle behavior in tumor spheres showed that CD133(+) cancer stem-like cells maintained stemness by remaining in G(0)-G(1) phase. We showed that OBP-301 mobilized quiescent cancer stem-like cells in tumor spheres and xenografts into S/G(2)/M phases where they lost viability and cancer stem-like cell properties and became chemosensitive.
Conclusion: Oncolytic adenoviralinfection is an effective mechanism of cancer cell killing in solid cancer and can be a new therapeutic paradigm to eliminate quiescent cancer stem-like cells. Clin Cancer Res; 19(23); 6495-505. (C) 2013 AACR.

記述言語：英語掲載種別：書評論文，書評，文献紹介等出版者・発行元：OKAYAMA UNIV MED SCHOOL

Autophagy is a catabolic process that produces energy through lysosomal degradation of intracellular organelles. Autophagy functions as a cytoprotective factor under physiological conditions such as nutrient deprivation, hypoxia, and interruption of growth factors. On the other hand, infection with pathogenic viruses and bacteria also induces autophagy in infected cells. Oncolytic virotherapy with replication-competent viruses is thus a promising strategy to induce tumor-specific cell death. Oncolytic adenoviruses induce autophagy and subsequently contribute to cell death rather than cell survival in tumor cells. We previously developed a telomerase-specific replication-competent oncolytic adenovirus, OBP-301, which induces cell lysis in tumor cells with telomerase activities. OBP-301-mediated cytopathic activity is significantly associated with induction of autophagy biomarkers. In this review, we focus on the tumor-suppressive role and molecular basis of autophagic machinery induced by oncolytic adenoviruses. Addition of tumor-specific promoters and modification of the fiber knob of adenoviruses supports the oncolytic adenovirus-mediated autophagic cell death. Autophagy is cooperatively regulated by the El-dependent activation pathway, E4-dependent inhibitory pathway, and microRNA-dependent fine-tuning. Thus, future exploration of the functional role and molecular mechanisms underlying oncolytic adenovirus-induced autophagy would provide novel insights and improve the therapeutic potential of oncolytic adenoviruses.

The luciferase reporter system is useful for the assessment of various biological processes in vivo. The transcription factor pancreatic and duodenal homeobox 1 (Pdx1) is critical for the formation and the function of pancreatic β-cells. A novel reporter system using secreted Gaussia princeps luciferase (GLuc) under the control of a Pdx1 promoter was generated and activated in rat and mouse β-cell lines. This Pdx1-GLuc construct was used as a transgene for the generation of reporter mice to monitor Pdx1 promoter activity in vivo via the measurement of secreted GLuc activity in a small aliquot of blood. Significantly increased plasma GLuc activity was observed in Pdx1-GLuc mice. Analysis of Pdx1-GLuc mice by bioluminescence imaging, GLuc reporter assays using homogenatesof various organs,andimmunohistochemistryrevealed thatGLucexpressionandactivity were exponentially higher in pancreatic β-cells than in pancreatic non-β-cells, the duodenum, and other organs. In addition, GLuc activity secreted into the culture medium from islets isolated from Pdx1-GLucmicecorrelatedwiththenumberofislets. ThetransplantationofPdx1-GLucisletsintosevere combined immunodeficiency mice elevated their plasma GLuc activity. Conversely, a partial pancreatectomy in Pdx1-GLuc mice reduced plasma GLuc activity. These results suggest that a secreted luciferase reporter system in vivo enables not only the monitoring of promoter activity but also a quantitative and minimally invasive assessment of physiological and pathological changes in small cell masses, such as pancreatic β-cells.

Currently-used rodent tumor models, including transgenic tumor models, or subcutaneously growing tumors in mice, do not sufficiently represent clinical cancer. We report here development of methods to obtain a highly clinically-accurate rectal cancer model. This model was established by intrarectal transplantation of mouse rectal cancer cells, stably expressing green fluorescent protein (GFP), followed by disrupting the epithelial cell layer of the rectal mucosa by instilling an acetic acid solution. Early-stage tumor was detected in the rectal mucosa by 6 days after transplantation. The tumor then became invasive into the submucosal tissue. The tumor incidence was 100% and mean volume (+/-SD) was 1232.4 +/- 994.7 mm(3) at 4 weeks after transplantation detected by fluorescence imaging. Spontaneous lymph node metastasis and lung metastasis were also found approximately 4 weeks after transplantation in over 90% of mice. This rectal tumor model precisely mimics the natural history of rectal cancer and can be used to study early tumor development, metastasis, and discovery and evaluation of novel therapeutics for this treatment-resistant disease.

Caffeine enhances the effect of certain anticancer drugs, but the mechanism of modulation is poorly understood. In this study, modulation of cisplatinum efficacy induced by caffeine was visualized at the subcellular level by real-time fluorescent-protein imaging. Mitotic and apoptotic changes were observed by imaging 143B human osteosarcoma dual-color cells, in which GFP is expressed in the nucleus and RFP is expressed in the cytoplasm. Modulation of the cell cycle was imaged using time-lapse imaging of HeLa cells expressing a fluorescent ubiquitination-based cell cycle indicator (FUCCI) in the nucleus. Clonogenic assays showed that caffeine increased the inhibition by cisplatinum on cell proliferation. Subcellular imaging demonstrated that cisplatinum decreased mitosis and induced apoptosis in 143B cells. The combination of cisplatinum and caffeine enhanced mitosis and subsequently increased apoptosis. Time-lapse imaging showed that cisplatinum strongly induced cell-cycle arrest in the S/G(2) phase in HeLa-FUCCI cells. Caffeine overcame the cell-cycle arrest induced by cisplatinum, thereby increasing its efficacy, since cisplatinum is ineffective against quiescent cells. The data in this report indicate that caffeine modulates the cell cycle in cancer cells, thereby enhancing efficacy of cell-cycle-dependent anticancer drugs such as cisplatinum. J. Cell.

Expert Opinion on Biological Therapy 13 ( 11 ) 1569 - 1583 2013年11月

記述言語：英語

Introduction: The tumor suppressor p53 gene regulates diverse cellular processes, such as cell-cycle arrest, senescence, apoptosis and autophagy, and it is frequently inactivated by genetic alterations in ∼ 50% of all types of human cancers. To restore wild-type p53 function in p53-inactivated tumors, adenovirus-mediated p53 gene therapy has been developed as a promising antitumor strategy in preclinical experiments and clinical studies. Areas covered: This review focuses on the clinical relevance of replication-deficient adenovirus vectors that carry the wild-type p53 gene (Ad-p53
Advexin, Gendicine and SCH-58500) in clinical studies of patients with various cancers and the future perspectives regarding conditionally replicating adenovirus vectors expressing the wild-type p53 gene (CRAd-p53
AdDelta24-p53, SG600-p53, OBP-702) in preclinical experiments. Moreover, the recent advances in our understanding of the molecular basis for the p53-mediated tumor suppression network induced by Ad-p53 and CRAd-p53 vectors and the combination therapies for promoting the therapeutic potential of adenovirus-mediated p53 gene therapy are discussed. Expert opinion: Exploration of the molecular mechanism underlying the p53-mediated tumor suppression network and the effective strategy for enhancing the p53-mediated cell death signaling pathway would provide novel insights into the improvement of clinical outcome in p53-based cancer gene therapy. © 2013 Informa UK, Ltd.

This study aimed to investigate the associations of the serial changes of serum levels of various growth factors with liver regeneration after hepatectomy in healthy liver donors. Sixteen healthy liver donors who underwent conventional liver resection were included. Serum levels of various growth factors before hepatectomy and on postoperative day (POD) 1, 3, 5 and 7 were measured. Liver volume data calculated by multi-detector computed tomography using workstation. The ratio of remnant liver volume on POD 0 to liver volume before the operation was 51% +/- 20%. The ratio of liver volume on POD 14 to liver volume on POD 0 were inversely correlated with remnant liver volume on POD 0 (r = -0.91). The ratio of liver volume on POD 14 to liver volume on POD 0 were significantly correlated with serum hepatocyte growth factor (HGF) levels on POD 1 (r = 0.54), serum leptin levels on POD 1 (r = 0.54), and serum macrophage colony-stimulating factor (M-CSF) levels on POD 5 (r = 0.76) and POD 7 (r = 0.80). These results suggest that early-phase elevation of serum levels of HGF, leptin and M-CSF may be associated with the acceleration of liver regeneration after hepatectomy in humans.

This study investigated the pathway underlying the antitumor activity of telomelysin, a telomerase-dependent, replication-selective oncolytic adenovirus, in soft tissue sarcoma cells. Treatment with telomelysin alone resulted in simultaneous induction of apoptosis and autophagy, whereas cotreatment with telomelysin and 3-methyladenine significantly reduced cell viability and increased apoptosis and the cellular ATP level compared to treatment with telomelysin alone, indicating that telomelysin-mediated autophagy is a death-protective but not death-promoting process. Cotreatment with Z-Val-Ala-Asp-CH2F significantly increased cellular ATP depletion compared to telomelysin-alone treatment while inhibiting telomelysin-induced apoptosis and having no significant effect on cell viability, indicating that it promotes transition from apoptotic to necrotic cell death. © 2013 Japanese Cancer Association.

Purpose: Peritoneal dissemination is the most frequent and life-threatening mode of metastasis and recurrence in patients with gastric cancer. A multicenter phase II study was designed to evaluate the efficacy and tolerability of S-1 and docetaxel combination chemotherapy regimen for the treatment of advanced or recurrent gastric cancer patients with peritoneal dissemination. Methods: Nineteen patients with histologically confirmed unresectable or recurrent gastric cancer with peritoneal dissemination were enrolled. Oral S-1 at 80 mg/m2/day was administered twice daily for 2 weeks, followed by 1 drug-free week. Docetaxel infusion at 40 mg/m2 was performed on day 1, simultaneous with S-1 administration. The primary endpoints were overall survival (OS) and time to progression (TTP). The secondary endpoints were the response rates and safety status. Results: Patients received a median of 4 cycles of the S-1 and docetaxel regimen (range 1-43). The disease control rate was 73.7 % (14/19). Median overall survival was 459 days (15.3 months), while median time to progression was 212 days (7.1 months). Neutropenia was the most common type of toxicity (n = 7, 36.8 %). Conclusions: Combination chemotherapy with S-1 and docetaxel is a tolerable and effective treatment for advanced or recurrent gastric cancer patients with peritoneal dissemination. © 2013 Springer-Verlag Berlin Heidelberg.

The telomerase-specific replication-competent oncolytic adenovirus, Telomelysin, was developed for virus-mediated preferential lysis of tumor cells. Its selectivity is derived from a human telomerase reverse transcriptase (hTERT) promoter-driven active viral replication, which occurs in cancer cells with high telomerase activity but not in normal cells lacking such activity. Because the TERT activity is elevated in most cases of hepatocellular carcinoma (HCC), the current study aims to investigate whether Telomelysin can be used for treatment of HCC. The oncolytic effect of Telomelysin has been investigated both in vitro using cell culture and in vivo using an immunocompetent in situ orthotopic HCC model. In this model, HCC developed spontaneously in the liver of HBx transgenic mice, which is pathologically and genetically similar to human HCC. In cell culture assay, Telomelysin lyses HCC cell lines at a low multiplicity of infection (MOI), ranging 0.77-6.35 (MOI [PFU/cell]). In the orthotopic HCC model, Telomelysin showed a potent oncolytic effect on HCC but spared normal liver tissue. Dose escalation analysis identified a safety dose of 1.25 X 108 PFU for this model. The effect of multiple injections of Telomelysin was also evaluated in this immunocompetent HCC model. We found that the virus replicates in HCC after a second intratumoral injection despite an immune response induced by the previous injection. This preclinical study shows that Telomelysin can be used for treatment of human HCC at an appropriate dosage and that its tumor-killing activity persists after multiple injections.

Esophageal squamous cell carcinoma (ESCC) remains one of the most aggressive cancers with poor prognosis regardless of a several reports that indicate a better therapeutic efficacy using some new chemotherapeutic agents. Recent drug development has contributed to an improved specificity to suppress mTOR activity by which many types of malignancies can be explosively progressed. Temsirolimus (CCI-779, TricelTM) is one of recently synthesized analogs of rapamycin and has provided better outcomes for patients with renal cell carcinoma. In this study, we experimentally evaluated an efficacy of targeting mTOR by temsirolimus for ESCC treatment, with an assessment of its survival advantage using an advanced ESCC animal model. First, we confirmed that the expression of phosphorylated mTOR was increased in 46 of 58 clinical ESCC tumor tissues (79.3%) and appeared to get strengthened with tumor progression. All of ESCC cell lines used in this study revealed an increase of mTOR phosphorylation, accompanied with the upregulation of hypoxia inducible factor-I α (HIF-1α), one of the critical effectors regulated by mTOR. Temsirolimus treatment apparently suppressed the activation of mTOR and its downstream effectors, resulting in the reduced ability of ESCC cell proliferation. Finally, the weekly administration of temsirolimus significantly diminished the size of subcutaneous tumors (vehicle, 3261.6 ± 722.0; temsirolimus, 599.2 ± 122.9; p = 0.007) in nude mice and effectively prolonged orthotopic esophageal cancer-bearing mice (median survival periods: control, 31 d; temsirolimus, 43 d; p = 0.0024). These data suggests that targeting mTOR by temsirolimus may become a therapeutic alternative for esophageal cancer, with a contribution to a better outcome.

Tumor suppressor p53 is a multifunctional transcription factor that regulates diverse cell fates, including apoptosis and autophagy in tumor biology. p53 overexpression enhances the antitumor activity of oncolytic adenoviruses; however, the molecular mechanism of this occurrence remains unclear. We previously developed a tumor-specific replication-competent oncolytic adenovirus, OBP-301, that kills human osteosarcoma cells, but some human osteosarcoma cells were OBP-301-resistant. In this study, we investigated the antitumor activity of a p53-expressing oncolytic adenovirus, OBP-702, and the molecular mechanism of the p53-mediated cell death pathway in OBP-301-resistant human osteosarcoma cells. The cytopathic activity of OBP-702 was examined in OBP-301-sensitive (U2OS and HOS) and OBP-301-resistant (SaOS-2 and MNNG/HOS) human osteosarcoma cells. The molecular mechanism in the OBP-702-mediated induction of two cell death pathways, apoptosis and autophagy, was investigated in OBP-301-resistant osteosarcoma cells. The antitumor effect of OBP-702 was further assessed using an orthotopic OBP-301-resistant MNNG/HOS osteosarcoma xenograft tumor model. OBP-702 suppressed the viability of OBP-301-sensitive and -resistant osteosarcoma cells more efficiently than OBP-301 or a replication-deficient p53-expressing adenovirus (Ad-p53). OBP-702 induced more profound apoptosis and autophagy when compared with OBP-301 or Ad-p53. E1A-mediated miR-93/106b upregulation induced p21 suppression, leading to p53-mediated apoptosis and autophagy in OBP-702-infected cells. p53 overexpression enhanced adenovirus-mediated autophagy through activation of damage-regulated autophagy modulator (DRAM). Moreover, OBP-702 suppressed tumor growth in an orthotopic OBP-301-resistant MNNG/HOS xenograft tumor model. These results suggest that OBP-702-mediated p53 transactivation is a promising antitumor strategy to induce dual apoptotic and autophagic cell death pathways via regulation of miRNA and DRAM in human osteosarcoma cells.

To monitor pancreatic islet transplantation efficiency, reliable noninvasive imaging methods, such as magnetic resonance imaging (MRI) are needed. Although an efficient uptake of MRI contrast agent is required for islet cell labeling, commercially-available magnetic nanoparticles are not efficiently transduced into cells. We herein report the in vivo detection of transplanted islets labeled with a novel cationic nanoparticle that allowed for noninvasive monitoring of islet grafts in diabetic mice in real time. The positively-charged nanoparticles were transduced into a β-cell line, MIN6 cells, and into isolated islets for 1 hr. MRI showed a marked decrease in the signal intensity on T1- and T2-weighted images at the implantation site of the labeled MIN 6 cells or islets in the left kidneys of mice. These data suggest that the novel positively-charged nanoparticle could be useful to detect and monitor islet engraftment, which would greatly aid in the clinical management of islet transplant patients. © 2013 Oishi et al.

Surgical site infections (SSIs), particularly organ/space SSIs, remain a common cause of major morbidity after hepatectomy for hepatocellular carcinoma (HCC).
Risk factors for SSIs were analyzed in 359 patients who underwent hepatectomy for HCC between 2001 and 2010. The causative bacteria, management, outcome, and characteristics of organ/space SSIs were investigated.
Anatomic hepatectomy was performed for 296 patients (82.5%), and repeat hepatectomy was carried out for 59 patients (16.4%). SSIs developed in 52 patients (14.5%; incisional, 24 cases; organ/space, 31 cases [3 patients showed both incisional and organ/space SSIs]). No in-hospital mortality related to incisional or organ/space SSIs was encountered. Independent risk factors for SSIs were repeat hepatectomy and operative time a parts per thousand yen280 min. Independent risk factors for organ/space SSIs were repeat hepatectomy and bile leakage. Methicillin-resistant Staphylococcus aureus was detected more frequently in organ/space SSIs after repeat hepatectomy than after initial hepatectomy.
Repeat hepatectomy and bile leakage represent independent risk factors for organ/space SSIs after hepatectomy for HCC. Establishing treatment strategies is important for preventing postoperative bile leakage and reducing the high rate of organ/space SSIs after repeat hepatectomy.

The discovery of practical biomarkers is important to realize personalized medicine for patients with malignant neoplasias, including colorectal cancer (CRC).
The aim of this study was to determine reliable prognostic biomarkers by the analysis of patients with resectable colorectal liver metastases (CRLM).
Genomic DNA was obtained from the CRLM tissues of a cohort of 126 patients with CRLM with curative hepatic resection. The KRAS/BRAF mutation spectrum and microsatellite instability (MSI) status were successfully analyzed in 100 of the 126 CRLM tissues and these findings were examined in relation to the patients' clinical outcomes.
The cohort of 100 CRLM patients consisted of 46 with synchronous and 54 with metachronous liver metastasis. Overall survival and disease-free survival at 5 years were 57.4 and 24.9 %, respectively. MSI analysis revealed that none of the 100 CRLM specimens showed any evidence of MSI. By KRAS/BRAF mutation analysis, the analyzed CRLM patients were divided into 3 groups; KRAS-mutant (KRAS-Mt; n = 27), BRAF-mutant (BRAF-Mt; n = 3), and wild-types of both genes (Wild-type; n = 70). In the survival analysis, both KRAS-Mt and BRAF-Mt patients showed significantly poorer prognoses compared with Wild-type patients. Furthermore, although the population with the BRAF mutation was small, this mutation had a significant negative impact on disease-free survival.
In this study, all tumors in the cohort of CRLM patients were non-MSI tumors, suggesting MSI cancer in primary CRC would rarely reveal metastatic potential. KRAS and BRAF mutations are suggested to be poor prognostic factors in CRLM. Genetic information has an essential role as a prognostic marker and could contribute to the decisions on treatment strategy for CRLM.

Living donor hepatectomy is important because it determines donor safety and recipient outcome.
We applied the counter-clockwise liver rotation method and the hanging maneuver from an early stage in two major types of living donor operations.
Twenty-eight living donors underwent these procedures with significant reduction in blood loss. Right hepatectomy was performed in 14 of the donors and extended left hepatectomy was performed in the other 14 donors.
These techniques facilitate safe and bloodless living donor hepatectomy.

Adenovirus serotype 5 (Ad5) is frequently used as an effective vector for induction of therapeutic transgenes in cancer gene therapy or of tumor cell lysis in oncolytic virotherapy. Ad5 can infect target cells through binding with the coxsackie and adenovirus receptor (CAR). Thus, the infectious ability of Ad5-based vectors depends on the CAR expression level in target cells. There are conventional methods to evaluate the CAR expression level in human target cells, including flow cytometry, western blotting and immunohistochemistry. Here, we show a simple system for detection and assessment of functional CAR expression in human tumor cells, using the green fluorescent protein (GFP)-expressing telomerase-specific replication-competent adenovirus OBP-401. OBP-401 infection induced detectable GFP expression in CAR-expressing tumor cells, but not in CAR-negative tumor cells, nor in CAR-positive normal fibroblasts, 24 h after infection. OBP-401-mediated GFP expression was significantly associated with CAR expression in tumor cells. OBP-401 infection detected tumor cells with low CAR expression more efficiently than conventional methods. OBP-401 also distinguished CAR-positive tumor tissues from CAR-negative tumor and normal tissues in biopsy samples. These results suggest that GFP-expressing telomerase-specific replication-competent adenovirus is a very potent diagnostic tool for assessment of functional CAR expression in tumor cells for Ad5-based antitumor therapy.

Background: Bile leakage, and organ and/or space surgical-site infection (SSI) are common causes of major morbidity after partial hepatectomy for hepatocellular carcinoma (HCC). The purpose of this study was to analyse risk factors for major morbidity and to explore strategies for its reduction after partial hepatectomy for HCC. Methods: Risk factors for bile leakage and organ/space SSI were analysed in patients who underwent partial hepatectomy for HCC between 2001 and 2010. The causes, management and outcomes of intractable bile leakage requiring endoscopic therapy or percutaneous transhepatic biliary drainage were analysed. In addition, causative bacteria, outcomes and characteristics of organ/space SSI were investigated. Risk factors were identified using multivariable analysis. Results: Some 359 patients were included in the analysis. The prevalence of bile leakage and organ/space SSI was 12.8 and 8.6 per cent respectively. Repeat hepatectomy and an operating time of at least 300 min were identified as independent risk factors for bile leakage. The main causes of intractable bile leakage were latent strictures of the biliary system caused by previous treatments for HCC and intraoperative injury of the hepatic duct during repeat hepatectomy. Independent risk factors for organ/space SSI were repeat hepatectomy and bile leakage. Methicillin-resistant Staphylococcus aureus was detected more frequently in organ/space SSI after repeat hepatectomy than after initial partial hepatectomy. Conclusion: Repeat hepatectomy and prolonged surgery were identified as risk factors for bile leakage after liver resection for HCC. Bile leakage and repeat hepatectomy increased the risk of organ/space SSI. Copyright (c) 2012 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.

Heat shock protein 90 (HSP90), a molecular chaperone, has provoked great interest as a promising molecular target for cancer treatment, due to its involvement in regulating the conformation, stability and functions of key oncogenic proteins. At present, a variety of chemical compounds targeting HSP90 have been developed and have shown convincing anti-neoplastic activity in various preclinical tumor models. The aim of our study was to evaluate the antitumor effects of a novel HSP90 inhibitor, NVP-AUY922, in esophageal squamous cancer cells (ESCC). Four ESCC cell lines (TE-1, TE-4, TE-8, TE-10) were examined. NVP-AUY922 potently inhibited the proliferation of ESCC, particularly in PTEN-null TE-4 cells with a 2-3 times lower IC50 than the other three cell lines. Western blot analysis showed that PTEN-null TE-4 cells exhibited higher AKT and ERK activity, which contribute to cell proliferation and survival. NVP-AUY922 significantly suppressed the activity of AKT and ERK in TE-4 but not in PTEN-proficient TE-10 cells. Genetic modification experiments demonstrated that the sensitivity to NVP-AUY922 was decreased by exogenous transduction of PTEN in TE-4 and increased by silencing PTEN expression in intact PTEN-expressing TE-10, suggesting that the expression of PTEN may be associated with cell sensitivity in HSP90 inhibition. Furthermore, the enhanced activity of AKT in PTEN-silenced TE-10 was more easily suppressed by NVP-AUY922. Collectively, NVP-AUY922 exhibits a strong antiproliferative effect, revealing its potential as a novel therapeutic alternative to current ESCC treatment. The effect may be improved further by impeding PTEN expression.

Immunotherapy is a potentially attractive treatment option for patients with hepatocellular carcinoma (HCC). We have reported that glypican-3 (GPC3) is an ideal target for anticancer immunotherapy against HCC because its expression is specifically detected in > 80% of HCCs, even during the early stages. Further, increased GPC3 expression is correlated with a poor prognosis. Based on results obtained from a preclinical study using mice, we conducted a phase I clinical trial using a GPC3-derived peptide vaccine. Phase I results showed that the GPC3-derived peptide vaccine was well tolerated. Furthermore, this was the first study to show that the frequency of peptide-specific cytotoxic T lymphocytes was correlated with overall survival in patients with HCC receiving a peptide vaccine. Next, we conducted a phase II clinical trial using the GPC3-derived peptide vaccine in patients with HCC after surgery or radiofrequency ablation (adjuvant setting). We are currently evaluating a third trial involving liver biopsies removed from patients with advanced HCC before and after GPC3-derived peptide vaccination. We expect that the results of these trials will result in future drug development.

A 79-year-old woman visited a previous hospital with a complaint of general fatigue. The patient was diagnosed with cecal cancer with multiple liver metastases and lymph node metastases on colonoscopy, abdominal ultrasonography and CT scan, and was referred to our division for treatment. Based on the diagnosis of non-curative colonic cancer, we planned to perform systematic chemotherapy after local surgical treatment. We performed an ileocecal resection, and the specimen showed poorly differentiated adenocarcinoma with mutation in the BRAF oncogene. After the surgical treatment, the tumor grew rapidly and the patient died from cancer on the 19th postoperative day without having the opportunity to undergo chemotherapy. Multiple genetic and epigenetic alterations in oncogenes and tumor suppressor genes are involved in the process of colorectal carcinogenesis. Some of the alterations have been identified as predictive and prognostic biomarkers. A mutation in the BRAF oncogene was reported to be associated with a very unfavorable prognosis in colorectal cancers. Some of the cases with rapid progression are suggested to have the BRAF oncogene mutation. According to our experience, chemotherapy before surgical treatment might improve the prognosis of cases with the BRAF mutation.

Introduction: The management of a large splenorenal shunt is important because it affects recipient outcome, particularly in living donor liver transplantation. Methods: To manage large splenorenal shunts in living donor liver transplantation, we diverted superior mesenteric vein and splenic portal vein blood flow by ligation at the root of the splenic portal vein. Result: This procedure was applied for five patients in whom superior mesenteric vein blood flow had been completely stolen by a splenorenal shunt preoperatively. Postoperative course was excellent in all cases. Conclusion: This technique completely prevents morbidity related to large splenorenal shunts after living donor liver transplantation. © 2012 The Society for Surgery of the Alimentary Tract.

The patient was a 70-year-old woman with gastrointestinal stromal tumor (GIST) of the small intestine, accompanied by liver metastasis. Multiple liver metastases were pointed out 3 months after R0 surgery (jejunectomy and hepatectomy). Although she was given radiofrequency ablation (RFA) therapy and imatinib, metastatic tumors progressed. In a further examination at our institution 21 months after R0 surgery, multiple liver, bone, and lung metastases were indicated, and she was given sunitinib once daily at a 50 mg in 6-week courses, with 4 weeks on and 2 weeks off treatment. Although sunitinib dosage was decreased to 25 mg/day because of adverse events, 21 courses of this treatment were administrered, and it took 137 weeks to progress her disease with this sunitinib treatment. At our institution, seven cases of GIST were treated with sunitinib, and the median time to progression was 30-weeks. That was almost the same result as for Japan and international clinical trials. Sunitinb treatment may be one of the most important therapeutic options for unresectable imatinib-resistant GIST.

Autophagy is known to have a cytoprotective role under various cellular stresses; however, it also results in robust cell death as an important safeguard mechanism that protects the organism against invading pathogens and unwanted cancer cells. Autophagy is regulated by cell signalling including microRNA (miRNA), a post-transcriptional regulator of gene expression. Here, we show that genetically engineered telomerase-specific oncolytic adenovirus induced miR-7 expression, which is significantly associated with its cytopathic activity in human cancer cells. Virus-mediated miR-7 upregulation depended on enhanced expression of the E2F1 protein. Ectopic expression of miR-7 suppressed cell viability and induced autophagy by inhibiting epidermal growth factor receptor (EGFR) expression. Our results suggest that oncolytic adenovirus induces autophagic cell death through an E2F1-miR-7-EGFR pathway in human cancer cells, providing a novel insight into the molecular mechanism of an anticancer virotherapy.

Background: Conventional reconstruction after an esophagectomy uses a gastric tube, which commonly causes several postoperative complaints such as gastric acid reflux in long-term survival cases. Intestinal interposition between the remnant esophagus and the stomach is an option to reduce complaints, and in this study, the advantages of jejunal interposition reconstruction with a stomach preserving esophagectomy (SPE) were assessed.
Materials and methods: Eleven cases of jejunal interposition with an SPE and 16 cases with gastric tube reconstruction as a control were subject to a comparison of operation time, amount of bleeding, postoperative quality of life, and endoscopic findings.
Results: The SPE group had a longer operation time (SPE: 560 +/- 121 min, control 414 +/- 83 min, P = 0.038), whereas there was no significant difference in blood loss. Postoperative weight loss was significantly recovered in the SPE group (SPE versus control = 94.0 +/- 5.4% versus 87.5 +/- 4.7% at 3 mo, P = 0.017; 97.2 +/- 7.5% versus 85.0 +/- 5.2% at 6 mo, P = 0.010), and there was a significant decrease in the occurrence of reflux symptoms such as heartburn, odynophagia, and cough when jejunal interposition with an SPE was done. Furthermore, reflux esophagitis and Barrett's epithelium were found in six out of 12 cases (50%) of the control group by postoperative endoscopy, while no cases in the SPE group had either condition (P < 0.01).
Conclusions: This reconstruction method is a promising option to improve postoperative quality of life, mainly due to the long-term elimination of reflux esophagitis, which assists in the recovery of postoperative weight loss. (C) 2012 Elsevier Inc. All rights reserved.

The small diameter of the hepatic artery is one of the complexities of living donor liver transplantation (LDLT). We analyzed whether the direct suture technique using surgical loupes can simplify the operative process for LDLT compared with fixed microscopic reconstruction. We applied the direct technique to rationalize the operative process and abolished routine microsurgery from 2004. Two hundred and nine LDLT with a postoperative period over 34 months were carried out from 1996 to 2008. The patients were divided into two groups: the micro group (children: 20, adults: 72) and the non-micro group (children: 12, adults: 97). Running anastomosis was undertaken in the non-micro group. The anastomotic size of the children was significantly smaller than that of the adults, but larger than 2 mm (2.38 +/- 0.4 vs. 2.7 +/- 0.47 mm, p = 0.0005). By appropriate choice of the proximal artery, direct anastomosis is possible even in children. Early complications occurred in seven cases in the micro group, but none occurred in the non-micro group (p < 0.05). Significant reductions were observed in operation time (p < 0.0001), blood loss (p < 0.05), and hospital stay (p < 0.01) in the non-micro group. Non-microscopic anastomosis is useful for the rationalization of LDLT.

Trastuzumab, a humanized antibody targeting HER2, exhibits remarkable therapeutic efficacy against HER2-positive breast and gastric cancers; however, acquired resistance presents a formidable obstacle to long-term tumor responses in the majority of patients. Here, we show the mechanism of resistance to trastuzumab in HER2-positive human cancer cells and explore the molecular sensitization by exogenous expression of HER2-extracellular domain (ECD) in HER2-negative or trastuzumab-resistant human cancer cells. We found that long-term exposure to trastuzumab induced resistance in HER2-positive cancer cells; HER2 expression was downregulated, and antibody-dependent cellular cytotoxicity (ADCC) activity was impaired. We next examined the hypothesis that trastuzumab-resistant cells could be re-sensitized by the transfer of non-functional HER2-ECD. Exogenous HER2-ECD expression induced by the stable transfection of a plasmid vector or infection with a replication-deficient adenovirus vector had no apparent effect on the signaling pathway, but strongly enhanced ADCC activity in low HER2-expressing or trastuzumab-resistant human cancer cells. Our data indicate that restoration of HER2-ECD expression sensitizes HER2-negative or HER2-downregulated human cancer cells to trastuzumab-mediated ADCC, an outcome that has important implications for the treatment of human cancers.

Replication-selective oncolytic viruses are being developed for human cancer therapy. We previously developed an attenuated adenovirus (OBP-301, Telomelysin), in which the human telomerase reverse transcriptase promoter element drives expression of E1A and E1B genes linked with an internal ribosome entry site. OBP-301 can replicate in, and causes selective lysis of, human cancer cells. Valproic acid (VPA), which is an effective antiepileptic drug, is known to inhibit the histone deacetylase activities. We determined whether the antitumor effect of OBP-301 could be enhanced by VPA in human lung cancer cells. In an in vitro cell viability assay, OBP-301 infection killed four human lung cancer cell lines, H1299, H1299-R5 (a subline of H1299 with a low level of the coxsackievirus and adenovirus receptor (CAR) expression), H460, and A549, more efficiently in the presence of VPA than in its absence. VPA treatment increased CAR expression in all the four lung cancer cells. Consistent with their CAR upregulation, the infection efficiency of adenoviruses in the presence of VPA was significantly higher than that in its absence. The molecular mechanism of this combined effect could be explained by an increase in adenovirus infectivity via VPA-mediated upregulation of CAR. These results suggest that treatment with OBP-301 in combination with VPA is a promising strategy for human lung cancer.

Oncolytic viruses engineered to replicate in tumour cells but not in normal cells could be used as tumour-specific vectors carrying the therapeutic genes. We previously developed a telomerase-specific oncolytic adenovirus, OBP-301, that causes cell death in human cancer cells with telomerase activities. Here, we further modified OBP-301 to express the wild-type p53 tumour suppressor gene (OBP-702), and investigated whether OBP-702 induces stronger antitumour activity than OBP-301. The antitumour effect of OBP-702 was compared to that of OBP-301 on OBP-301-sensitive (H358 and H460) and OBP-301-resistant (T.Tn and HSC4) human cancer cells. OBP-702 suppressed the viability of both OBP-301-sensitive and OBP-301-resistant cancer cells more efficiently than OBP-301. OBP-702 caused increased apoptosis compared to OBP-301 or a replication-deficient adenovirus expressing the p53 gene (Ad-p53) in H358 and T.Tn cells. Adenovirus E1A-mediated p21 and MDM2 downregulation was involved in the apoptosis caused by OBP-702. Moreover, OBP-702 significantly suppressed tumour growth in subcutaneous tumour xenograft models compared to monotherapy with OBP-301 or Ad-p53. Our data demonstrated that OBP-702 infection expressed adenovirus E1A and then inhibited p21 and MDM2 expression, which in turn efficiently induced apoptotic cell death. This novel apoptotic mechanism suggests that the p53-expressing OBP-702 is a promising antitumour reagent for human cancer and could improve the clinical outcome. (C) 2011 Elsevier Ltd.

BACKGROUND: Recently developed detection system for circulating tumour cells (CTCs) using a telomerase-specific replicative adenovirus generated nonspecific green fluorescent protein (GFP) signals because of the co-presence of white blood cells (WBCs) nonspecifically infected by viruses. Here, we established a unique detection system for CTCs that completely excludes nonspecific signals.
METHODS: Blood obtained from the patients was subjected to haemolytic processes to eliminate red blood cells. The cell pellets were then infected with OBP-401, fixed, incubated with fluorescence-labelled anti-CD45 antibody to mark white blood WBCs, and examined on slides under a microscope.
RESULTS: Preparatory experiments with cancer cells artificially added to healthy donor samples confirmed that CD45 labelling could distinguish GFP-positive cancer cells from WBCs. In 53 patients with gynaecological cancers, CTCs were detected in 21 patients (39.6%) when CD45-positive cells were excluded as WBCs among GFP-positive cells. No CTCs were detected in samples from healthy volunteers. There was no significant correlation between CTC counts and known clinicopathological factors. The CTCs rapidly vanished after surgery or chemotherapy in most patients whose treatments were effective. In contrast, the persistence of CTCs even after treatments was tightly associated with poor response to the treatments (P<0.005).
CONCLUSION: The presence of CTCs in our system may potentially be a novel therapeutic marker in gynaecological cancers. British Journal of Cancer (2012) 107, 448-454. doi: 10.1038/bjc.2012.276 www.bjcancer.com Published online 26 June 2012 (C) 2012 Cancer Research UK

Peritoneal dissemination is one of the most terrible types of colorectal cancer progression. Focal adhesion kinase (FAK) plays a crucial role in the biological processes of cancer, such as cell attachment, migration, proliferation and survival, all of which are essential for the progression of peritoneal dissemination. Since we and other groups have reported that the inhibition of FAK activity exhibited a potent anticancer effect in several cancer models, we hypothesized that TAE226, a novel ATP-competitive tyrosine kinase inhibitor designed to target FAK, can prevent the occurrence and progression of peritoneal dissemination. In vitro, TAE226 greatly inhibited the proliferation and migration of HCT116 colon cancer cells, while their adhesion on the matrix surface was minimally inhibited when FAK activity and expression was suppressed by TAE226 and siRNA. In vivo, when HCT116 cells were intraperitoneally inoculated in mice, the cells could attach to the peritoneum and begin to grow within 24 h regardless of the pretreatment of cells with TAE226 or FAK-siRNA, suggesting that FAK is not essential, at least for the initial integrin-matrix contact. Interestingly, the treatment of mice before and after inoculation significantly suppressed cell attachment to the peritoneum. Furthermore, oral administration of TAE226 greatly reduced the size of disseminated tumors and prolonged survival in tumor-bearing mice. Taken together, a possible strategy for inhibiting peritoneal dissemination by targeting FAK with TAE226 appears to be applicable through anti-proliferative and anti-invasion/anti-migration mechanisms.

Malnutrition and metabolic disorder of patients undergoing living donor liver transplantation (LDLT) can affect post-transplant prognosis. The aim of this study was to establish whether perioperative usage of branched-chain amino-acid (BCAA)-enriched nutrients improve metabolic abnormalities of patients undergoing LDLT.
We designed a randomized pilot study (UMIN registration number; 000004323). Twenty-five consecutive adult elective LDLT recipients were enroled and divided into two groups: the BCAA group (BCAA-enriched nutrients, n = 12) and the control group (standard diet, n = 13). Metabolic and nutritional parameters, including BCAA-to-tyrosine ratio (BTR), retinol binding protein (RBP), and prealbumin were regularly measured from 1 week before to 4 weeks after LDLT. Non-protein respiratory quotient (npRQ) was measured before and 4 weeks after LDLT.
BTR and RBP improved considerably in the BCAA group compared with the controls. npRQ significantly increased from 1 week before LDLT to 4 weeks after LDLT in the BCAA group (0.77 +/- A 0.05 to 0.84 +/- A 0.06, P = 0.002), but not in the control group (0.78 +/- A 0.04 to 0.81 +/- A 0.05).
Supplementation with BCAA-enriched nutrients might improve persistent nutritional and metabolic disorders associated with end-stage liver disease in the early post-transplant period, and consequently shorten the post-transplant catabolic phase after LDLT. A larger multicenter trial is needed to confirm these findings.

Aim: To assess the effects of a novel type 1 insulin-like growth factor receptor (IGF-1R) inhibitor, NVP-AEW541, on cell proliferation and signal transduction of esophageal cancer. Materials and Methods: Cell proliferation assay and western blot were conducted to assess the antitumor effects of NVP-AEW541. Genetic modification of RAS by expression vector was applied for overexpression of mutant RAS. Results: More than 2 mu mol/l of NVP-AEW541 was required to effectively, inhibit the proliferation of esophageal cancer NVP-AEW541 potently blocked the activation of IGF-IR and protein kinase B (PKB, also known as AKT), but not of mitogen-activated protein kinase kinase (MEK) and extracellular-signal-regulated kinases (ERK). Active RAS was not reduced by NVP-AEW541 in esophageal cancer cells TE-1, suggesting that insensitivity of esophageal cancer to NVP-AEW541 is due to the maintained RAS-MAPK activity, which did not arise from RAS mutation. Moreover, the transduction of mutant RAS reduced the sensitivity of TE-1 cells to NVP-AEW541. Conclusion: Stimulation of RAS-MAPK pathway is associated with resistance to NVP-AEW541 in esophageal cancer. Combining NVP-AEW541 with inhibitors/antibodies against RAS-MAPK signaling molecules might be more effective for use against esophageal cancer.

Hypoxia is a microenvironmental factor that contributes to the invasion, progression and metastasis of tumor cells. Hypoxic tumor cells often show more resistance to conventional chemoradiotherapy than normoxic tumor cells, suggesting the requirement of novel antitumor therapies to efficiently eliminate the hypoxic tumor cells. We previously generated a tumor-specific replication-competent oncolytic adenovirus (OBP-301: Telomelysin), in which the human telomerase reverse transcriptase (hTERT) promoter drives viral E1 expression. Since the promoter activity of the hTERT gene has been shown to be upregulated by hypoxia, we hypothesized that, under hypoxic conditions, the antitumor effect of OBP-301 with the hTERT promoter would be more efficient than that of the wild-type adenovirus 5 (Ad5). In this study, we investigated the antitumor effects of OBP-301 and Ad5 against human cancer cells under a normoxic (20% oxygen) or a hypoxic (1% oxygen) condition. Hypoxic condition induced nuclear accumulation of the hypoxia-inducible factor-1 alpha and upregulation of hTERT promoter activity in human cancer cells. The cytopathic activity of OBP-301 was significantly higher than that of Ad5 under hypoxic condition. Consistent with their cytopathic activity, the replication of OBP-301 was significantly higher than that of Ad5 under the hypoxic condition. OBP-301-mediated E1A was expressed within hypoxic areas of human xenograft tumors in mice. These results suggest that the cytopathic activity of OBP-301 against hypoxic tumor cells is mediated through hypoxia-mediated activation of the hTERT promoter. Regulation of oncolytic adenoviruses by the hTERT promoter is a promising antitumor strategy, not only for induction of tumor-specific oncolysis, but also for efficient elimination of hypoxic tumor cells.

Carcinosarcomas of the gallbladder are rare tumors that are characterized by malignant epithelial and mesenchymal components, and preoperative diagnosis of carcinosarcoma of the gallbladder remains difficult.
We recently encountered a case of carcinosarcoma of the gallbladder with osteoid and chondroid differentiation, manifesting as cholangitis due to hemobilia.
Preoperative computed tomography and magnetic resonance imaging indicated the cause of cholangitis and provided qualitative information regarding the two components of the tumor.

The purpose of this study was to show the long-term outcome of induction chemoradiotherapy, using docetaxel and cisplatin with concurrent radiotherapy followed by surgery for non-small-cell lung cancer (NSCLC) with mediastinal nodal metastasis. Between January 2000 and July 2006, 22 consecutive NSCLC patients with pathologically proven mediastinal nodal metastasis were treated with tri-modality therapy. The regimen consisted of docetaxel and cisplatin plus concurrent radiation at a dose of 40-46 Gy. The induction therapy was followed by surgery 4-6 weeks later. The pulmonary resections were composed of a lobectomy in 19 patients, including 3 with a sleeve lobectomy, a bilobectomy in 2 patients and a left pneumonectomy in 1 patient. With a median follow-up duration of 8.7 years, the 3-year and 7-year overall survival (OS) rates for the entire population were 72.7 and 63.6%, respectively. Our results suggest that tri-modality therapy is promising for NSCLC patients with mediastinal nodal metastasis.

We report 4 cases of surgical resection of metachronous lymph node (LN) metastases from hepatocellular carcinoma (HCC) following hepatectomy. Clinicopathological features and results of LN dissection were investigated in the 4 patients. One patient was found to have a single metastasis in the mediastinal LNs, another had multiple metastases in the mediastinal and abdominal LNs, and the other 2 had single metastases in the abdominal LN. The locations of the abdominal LN metastases were behind the pancreas head in 2 patients and around the abdominal aorta in 1 patient. They all underwent surgical resection of metastatic LNs and had no postoperative complications. The 3 patients whose LN metastases were solitary have been alive for more than 2 years after LN resection, and one of them is free from recurrence. The patient with multiple LN metastases died 13 months after LN resection due to carcinomatosis. With the expectation of long-term survival, a single metachronous LN metastasis from HCC after hepatectomy should be resected in patients without uncontrollable intrahepatic or extrahepatic tumors.

記述言語：英語掲載種別：書評論文，書評，文献紹介等出版者・発行元：OKAYAMA UNIV MED SCHOOL

Radiotherapy plays a central part in cancer treatment, and use of radiosensitizing agents can greatly enhance this modality. Although studies have shown that several chemotherapeutic agents have the potential to increase the radiosensitivity of tumor cells, investigators have also studied a number of molecularly targeted agents as radiosensitizers in clinical trials based on reasonably promising preclinical data. Recent intense research into the DNA damage-signaling pathway revealed that ataxia-telangiectasia mutated (ATM) and the Mre11-Rad50-NBS1 (MRN) complex play central roles in DNA repair and cell cycle checkpoints and that these molecules are promising targets for radiosensitization. Researchers recently developed three ATM inhibitors (KU-55913, CGK733, and CP466722) and an MRN complex inhibitor (mirin) and showed that they have great potential as radiosensitizers of tumors in preclinical studies. Additionally, we showed that a telomerase-dependent oncolytic adenovirus that we developed (OBP-301 [telomelysin]) produces profound radiosensitizing effects by inhibiting the MRN complex via the adenoviral E1B55kDa protein. A recent Phase I trial in the United States determined that telomelysin was safe and well tolerated in humans, and this agent is about to be tested in combination with radiotherapy in a clinical trial based on intriguing preclinical data demonstrating that telomelysin and ionizing radiation can potentiate each other. In this review, we highlight the great potential of ATM and MRN complex inhibitors, including telomelysin, as radiosensitizing agents.

Background/Aims: An omental flap covering the splanchnic vessels might reduce postoperative intra-abdominal hemorrhage after pancreaticoduodenectomy. However, the efficiency of such a procedure remains to be verified. The purpose of this study was to determine the effect of mental flap placement in pancreaticoduodenectomy on the incidence of postoperative pseudoaneurysms. Methodology: Of 229 consecutive patients who underwent pancreaticoduodenectomy, the most recent 157 patients received the omental flap, while the initial 72 patients had no omental flap placement. Various preoperative factors were considered in the evaluation (age, gender, body mass index, primary disease and concurrent disease), as well as operative factors (operation time, blood loss, operative procedures, pancreatic texture, size of pancreatic duct and surgeon's experience). Results: Eighty-one patients (35.4%) developed pancreatic fistula. Nine patients (3.9%) developed postoperative pseudoaneurysm. Among the patients with pancreatic fistula, those without omental flap developed pseudoaneurysms more frequently (21.7%) than those with omental flap placement (5.2%). Multivariate analysis identified pancreatic fistula, no use of mental flap and hypertension, in that order, as predisposing factors for a pseudoaneurysm. The omental flap significantly prevented pseudoaneurysms (p=0.021; OR=0.151; 95% CI, 0.030-0.751). Conclusions: Omental flap placement over splanchnic vessels could be a feasible and efficient surgical procedure to prevent postoperative pseudoaneurysms following pancreaticoduodenectomy.

Glypican-3 (GPC3), a carcinoembryonic antigen, is an ideal target for anticancer immunotherapy against hepatocellular carcinoma (HCC). In this study, we attempted to compare the induction of the GPC3-specific T-cell-mediated immune response after locoregional therapies in HCC patients and tumor-bearing mice. Twenty-seven HCC patients treated with locoregional therapies, including radiofrequency ablation (RFA), surgical resection and transcatheter arterial chemoembolization (TACE), were prospectively enrolled in this study. Additionally, we performed RFA experiments using a mouse model. GPC3-specific T-cell response was investigated pretreatment and post-treatment by an interferon-gamma enzyme-linked immunospot assay using peripheral blood mononuclear cells from HCC patients and lymph node cells from tumor-bearing mice. Circulating GPC3-specific cytotoxic T lymphocytes (CTLs) were increased in 5 of 9 patients after RFA and in 4 of 9 patients after TACE, but in only 1 of 9 patients after surgical resection. All 7 patients with GPC3-expressing HCCs exhibited an increase in GPC3-specific CTLs after RFA or TACE, whereas none of the 7 patients did after surgical resection. The number of increased GPC3-specific CTLs after RFA was significantly larger than that after surgical resection (P=0.023). Similarly, the frequency of GPC3-specific CTLs after RFA was significantly greater than that after surgical resection in the mouse model (P=0.049). We validated for the first time the stronger effect on the immune system brought by RFA compared with surgical resection for HCC patients and tumor-bearing mice. Combined treatment of RFA and immunotherapy is a reasonable strategy against HCC.

We experienced a case of gastric aberrant pancreas with acute pancreatitis. The patient was a 42-year-old man. He was referred to our hospital because of epigastric pain. A CT scan and endoscopic examination revealed a gastric submucosal tumor with inflammation. His serum amylase level was high at 222 IU/l. Endoscopic ultrasonography revealed a hypoechoic mass lesion, 3 cm in diameter, at the body of his stomach. Endoscopic ultrasoundscopy-guided fine needle aspiration was performed. Pathological examination showed pancreatic tissue. So, he underwent partial gastrectomy due to gastric aberrant pancreas with pancreatitis. There are very few cases of gastric aberrant pancreas with pancreatitis on record.

A 59-year-old man with epigastric discomfort and anorexia was referred to our hospital. Endoscopy revealed a type 3 advanced gastric cancer with pyloric stenosis diagnosed as a poorly differentiated adenocarcinoma in the biopsy specimens. A gastrojejunal bypass operation was performed because of direct invasion to the pancreas. The patient was treated by three courses of neoadjuvant chemotherapy with S-1/CDDP. Follow-up abdominal CT scan revealed that the primary tumor had become smaller, suggesting that a partial response had been achieved. Distal gastrectomy with D2 lymphadenectomy was performed. The histopathological examination showed no residual cancer cells in the primary lesion or dissected lymph nodes. Final chemotherapy efficacy was evaluated as Grade 3. The patient was treated with S-1 for one year after the gastrectomy and lymphadenectomy and has been followed up for 18 months without evidence of recurrence.

Background/Aims: Bile leakage is still a common cause of major morbidity after hepatectomy for hepatocellular carcinoma (HCC). The purpose of this study was to identify characteristics and risk factors for intractable bile leakage after hepatectomy for HCC. Methods: Risk factors for bile leakage were analyzed in 359 patients who underwent hepatectomy for HCC between 2001 and 2010. The causes, management and outcomes of intractable bile leakage which needed endoscopic therapy or percutaneous transhepatic biliary drainage were investigated. Results: A total of 296 patients (82.5%) underwent an anatomic hepatectomy, and a repeat hepatectomy was carried out in 59 patients (16.4%). The prevalence of bile leakage was 12.8%, and 8 patients had intractable bile leakage. An operative time >= 300 min was an independent risk factor for bile leakage after hepatectomy for HCC. The main causes of intractable bile leakage were a latent stricture of the biliary anatomy caused by previous treatments for HCC and intraoperative injury of the hepatic duct related to repeat hepatectomy. Conclusion: To help prevent intractable bile leakage, a preoperative assessment of the biliary anatomy and surgical procedures to decrease the incidence of major bile leakage should be considered for selected patients with a high risk for intractable bile leakage.

症例は79歳、男性。十二指腸潰瘍の手術既往による残胃の吻合部に残胃癌を指摘され、残胃部分切除・Roux-en-Y再建を行った。術後Treitz靱帯近傍に再発腫瘍を指摘され、化学療法を施行中に腸閉塞症状が出現した。CTで十二指腸の著明な拡張を認め、既知の再発腫瘍によるY脚部の通過障害と診断した。閉塞部位が一ヶ所であったことから、ダブルバルーン小腸内視鏡を用い狭窄部にステントを留置した。ステント留置後腸閉塞は解除され、経口摂取と化学療法の再開が可能となった。近年普及してきたダブルバルーン内視鏡により従来困難であったRoux-en-Y再建後の十二指腸側Y脚へのアプローチが可能となった。本症例では狭窄部へのステント留置により手術を回避し得たことから、緩和治療として悪性腸閉塞症治療の1選択肢になり得ると考え報告する。(著者抄録)

骨・軟部肉腫は, 一部に治療抵抗性で予後の悪い症例が存在するため, 新たな治療法の確立が重要な課題である. 我々は, 5型アデノウイルスを基本骨格として, テロメラーゼ活性に依存して増殖する腫瘍融解ウイルス（OBP-301）や, coxsackie and adenovirus receptor（CAR）陰性の腫瘍細胞に感染するファイバー改変型ウイルス（OBP-405）を用い, 骨・軟部肉腫細胞に対する抗腫瘍効果を検討した. 14種類の骨・軟部肉腫細胞株に対してOBP-301の細胞障害活性を検討し, 12種類の細胞株でOBP-301に感受性を認めた. また, OBP-301の細胞障害活性はCARの発現と相関していた. さらに, テロメラーゼ活性の低い細胞に対しても, 5型アデノウイルスの複製に必須のE1Aによりテロメラーゼ活性の増強効果がおこり, 強い抗腫瘍活性を示すことを明らかにした. 次に, 骨肉腫脛骨同所性移植動物モデルを作成しOBP-301を投与したところ, OBP-301投与群では対象群と比べて有意に腫瘍増殖を抑制した. 最後に, OBP-301に感受性を認めなかったCAR陰性細胞株に対してOBP-405を用いて検討し, OBP-405が有効に作用することを確認した. OBP-301やOBP-405を用いたウイルス療法は, 骨・軟部肉腫に対する新たな治療法となる可能性がある.

Purpose: Evaluating the status of disease progression is critical for planning a therapeutic strategy for esophageal cancer. In this regard, F-18 fluorodeoxyglucose-labeled positron emission tomography (PET) is one of the most useful diagnostic modalities. However, there is room to improve its diagnostic performance, such as distinguishing lymph nodal metastases from false positives. In this study, we examined the diagnostic accuracy of fluorodeoxyglucose PET accompanied by computed tomography imaging (PET/CT) to detect regional lymph nodal metastasis from esophageal squamous cell carcinoma (ESCC).
Methods: A total of 102 patients diagnosed as ESCC were subjected to this study. These patients had a preoperative PET/CT examination to evaluate the existence of metastasis. The values of maximum standardized uptake value (SUVmax) in primary tumors and in metastasized lymph nodes were measured to analyze their relationship with various clinicopathologic characteristics including the status of tumor cell proliferation, which was assessed by immunohistochemistry for Ki-67.
Results: The SUVmax of the primary tumor was positively correlated with tumor size and vessel invasion, and was positively related with the SUVmax of lymph nodal metastasis, especially in cases of poorly differentiated ESCC. The SUVmax of metastasized lymph nodes was higher in larger-sized metastasized lymph nodes, whereas the Ki-labeling index of lymph nodal metastasis was positively related with the SUVmax per unit area (SUVmax/mm(2)). The diagnostic accuracy of PET/CT (87.3%) was higher than that of conventional CT scans (78.4%).
Conclusions: The improved diagnostic accuracy of PET/CT can be explained by its ability to detect actively progressive metastasis at an early phase regardless of size.

We have previously developed a telomerase-specific replicating adenovirus expressing GFP (OBP-401), which can selectively label tumors in vivo with GFP. Intraperitoneal (i.p.) injection of OBP-401 specifically labeled peritoneal tumors with GFP, enabling fluorescence visualization of the disseminated disease and real-time fluorescence surgical navigation. However, technical problems of removing all cancer cells still remain, even with fluorescence-guided surgery. In this study, we report that in vivo OBP-401 labeling of tumors with GFP before fluorescence-guided surgery reports cancer recurrence after surgery. Recurrent tumor nodules brightly expressed GFP, indicating that initial OBP-401-GFP labeling of peritoneal disease was genetically stable such that proliferating residual cancer cells still express GFP. In situ tumor labeling with a genetic reporter has important advantages over antibody and other non-genetic labeling of tumors, since residual disease remains labeled during recurrence and can be further resected under fluorescence guidance.

Temsirolimus (CCI-779), a recently synthesized analogue of rapamycin, specifically inhibits mTOR and has been approved for clinical use in renal cell carcinoma. Recent reports have indicated the growth inhibitory effect of temsirolimus in some cancers including non-small-cell lung carcinoma (NSCLC). In this study, we aimed to explore the potential therapeutic use of temsirolimus as a treatment for NSCLC. Using cultured NSCLC cells (A549, H1299, and H358), we determined the effect of temsirolimus on cell proliferation and its antitumor effects on subcutaneous tumors, as well as its contribution to the survival of mice having pleural dissemination of cancer cells, mimicking advanced NSCLC. Temsirolimus suppressed proliferation of NSCLC cells in a dose-dependent manner, with an IC(50) of < 1 nM. Western blot analysis revealed that temsirolimus treatment specifically inhibited the phosphorylation of mTOR and its downstream effectors in 1 h, accompanied by an increased cell population in the G(0)/G(1) phase, but according to flow cytometry, the cell population did not increase in the sub-G(0) phase. When NSCLC subcutaneous tumor-bearing mice were treated with temsirolimus, tumor volume was significantly reduced (tumor volume on day 35: vehicle vs temsirolimus = 1239 vs 698 cm(3); P < 0.05). Furthermore, prolonged survival was observed in pleural disseminated tumor-bearing mice with temsirolimus treatment (median survival: vehicle vs temsirolimus = 53.5 vs 72.5 days; P < 0.05). These results suggest that temsirolimus could be useful for NSCLC treatment, due to its antiproliferative effect, and could be a potential treatment for advanced NSCLC, giving prolonged survival.

A telomerase-specific oncolytic adenovirus, Telomelysin, can selectively kill cancer cells, and be attenuated in normal cells. We herein describe the oncolytic effect of Telomelysin on human osteosarcoma both in vitro and in vivo.
The anti-tumor effects of Telomelysin were evaluated on human osteosarcoma cell lines in vitro and in a mouse xenograft model of human osteosarcoma in vivo. The replication efficiencies of Telomelysin in human osteosarcoma cell lines and normal cell lines and in osteosarcoma xenografts were determined by the expression levels of E1 mRNA and E1A protein using real-time quantitative PCR, Western blot analysis and immunohistochemistry. The in vitro telomerase-specific replication and the viral infection rate were also confirmed by TelomeScan (Telomelysin-GFP), using fluorescent microscopy and flow cytometry, respectively. The cell viabilities were examined by XTT assay, and the tumor volumes were measured every 2 days. The induction of apoptosis was assessed by Western blot analysis, as well as by TUNEL assay.
TelomeScan and Telomelysin were efficiently replicated in human osteosarcoma cell lines and led to a dose- and time-dependent expression of GFP, E1 mRNA and E1A protein. Telomelysin infection induced marked cytolysis and apoptosis in osteosarcoma cell lines in vitro. Neither cytotoxicity nor apoptosis were induced in normal human cell lines. In the human osteosarcoma cell xenograft model, intratumoral injection of Telomelysin resulted in increased viral replication, significant tumor growth suppression and distinct apoptotic cell death.
This study indicated that virotherapy with Telomelysin may provide a promising strategy for the treatment of human osteosarcoma.

Purpose: Oncolytic adenoviruses (Ad) have been actively pursued as potential agents for cancer treatment. Among the various types of oncolytic Ads, the telomerase-specific replication-competent Ad (TRAD), which possesses an E1 gene expression cassette driven by the human telomerase reverse transcriptase promoter, has shown promising results in human clinical trials; however, the E1 gene is also slightly expressed in normal cells, leading to replication of TRAD and cellular toxicity in normal cells.
Experimental Design: To overcome this problem, we utilized a microRNA (miRNA)-regulated gene expression system. Four copies of complementary sequences for miR-143, -145, -199a, or let-7a, which have been reported to be exclusively downregulated in tumor cells, were incorporated into the 3'-untranslated region of the E1 gene expression cassette.
Results: Among the TRAD variants (herein called TRADs) constructed, TRADs containing the sequences complementary to miR-143, -145, or -199a showed efficient oncolytic activity comparable to the parental TRAD in the tumor cells. On the other hand, replication of the TRADs containing the miRNA complementary sequences was at most 1,000-fold suppressed in the normal cells, including primary normal cells. In addition, to suppress the replication of the TRADs in hepatocytes as well as other normal cells, we constructed a TRAD containing 2 distinct complementary sequences for miR-199a and liver-specific miR-122a (TRAD-122a/199aT). TRAD-122a/199aT exhibited more than 10-fold reduction in viral replication in all the normal cells examined, including primary hepatocytes.
Conclusions: This study showed that oncolytic Ads containing the sequences complementary to normal cell-specific miRNAs showed significantly improved safety profiles without altering tumor cell lysis activity. Clin Cancer Res; 17(9); 2807-18. (C)2011 AACR.

Replication-selective tumor-specific viruses present a novel approach for treatment of neoplastic disease. These vectors are designed to induce virus-mediated lysis of tumor cells after selective viral propagation within the tumor. Human telomerase is highly active in more than 85% of primary cancers, regardless of their tissue origins, and its activity correlates closely with human telomerase reverse transcriptase (hTERT) expression. We constructed an attenuated adenovirus 5 vector (OBP-301), in which the hTERT promoter element drives the expression of El genes. Since only tumor cells that express telomerase activity are able to activate this promoter, the hTERT proximal promoter allows for preferential expression of viral genes in tumor cells, leading to selective viral replication and oncolytic cell death. Lymphatic invasion is a major route for cancer cell dissemination, and adequate treatment of locoregional lymph nodes is required for curative treatment in patients with gastrointestinal tumors. In this article we show that intratumoral injection of OBP-301 mediates effective in vivo purging of metastatic tumor cells from regional lymph nodes, which may help optimize treatment of human gastrointestinal malignancies.

AIM: To investigate the possible biological outcome and effect of glutamine depletion in neonatal mice and rodent intestinal epithelial cells.
METHODS: We developed three kinds of artificial milk with different amounts of glutamine; Complete amino acid milk (CAM), which is based on maternal mouse milk, glutamine-depleted milk (GDM), and glutaminerich milk (GRM). GRM contains three-fold more glutamine than CAM. Eighty-seven newborn mice were divided into three groups and were fed with either of CAM, GDM, or GRM via a recently improved nipple-bottle system for seven days. After the feeding period, the mice were subjected to macroscopic and microscopic observations by immunohistochemistry for 5-bromo-2'-deoxyuridine (BrdU) and Ki-67 as markers of cell proliferation, and for cleaved-caspase-3 as a marker of apoptosis. Moreover, IEC6 rat intestinal epithelial cells were cultured in different concentrations of glutamine and were subject to a 4-[3-(4-iodophenyl)-2-(4-nitrophenyl)-2H-5-tetrazolio]-1,3-benzene disulfonate cell proliferation assay, flow cytometry, and western blotting to examine the biological effect of glutamine on cell growth and apoptosis.
RESULTS: During the feeding period, we found colonic hemorrhage in six of 28 GDM-fed mice (21.4%), but not in the GRM-fed mice, with no differences in body weight gain between each group. Microscopic examination showed destruction of microvilli and the disappearance of glycocalyx of the intestinal wall in the colon epithelial tissues taken from GDM-fed mice. Intake of GDM reduced BrdU incorporation (the average percentage of BrdU-positive staining; GRM: 13.8%, CAM: 10.7%, GDM: 1.14%, GRM vs GDM: P < 0.001, CAM vs GDM: P < 0.001) and Ki-67 labeling index (the average percentage of Ki-67-positive staining; GRM: 24.5%, CAM: 22.4% GDM: 19.4%, GRM vs GDM: P = 0.001, CAM vs GDM: P =0.049), suggesting that glutamine depletion inhibited cell proliferation of intestinal epithelial cells. Glutamine deprivation further caused the deformation of the nuclear membrane and the plasma membrane, accompanied by chromatin degeneration and an absence of fat droplets from the colonic epithelia, indicating that the cells underwent apoptosis. Moreover, immunohistochemical analysis revealed the appearance of cleaved caspase-3 in colonic epithelial cells of GDM-fed mice. Finally, when IEC6 rat intestinal epithelial cells were cultured without glutamine, cell proliferation was significantly suppressed after 24 h (relative cell growth; 4 mmol/L: 100.0% 36.1%, 0 mmol/L: 25.3% 25.0%, P < 0.05), with severe cellular damage. The cells underwent apoptosis, accompanied by increased cell population in sub-GO phase (4 mmol/L: 1.68%, 0.4 mmol/L: 1.35%, 0 mmol/L: 5.21%), where dying cells are supposed to accumulate.
CONCLUSION: Glutamine is an important alimentary component for the maintenance of intestinal mucosa. Glutamine deprivation can cause instability of the intestinal epithelial alignment by increased apoptosis. (C) 2011 Baishideng. All rights reserved.

Background The aim of this study was to evaluate the prognostic factors for intrahepatic recurrence of hepatocellular carcinoma (HCC) after curative resection.
Methods Of 297 patients with HCC who underwent curative resection between 1998 and 2007, 145 had intrahepatic recurrence, and 125 of these were enrolled in this study. We analyzed the relationships between overall survival after HCC recurrence and 20 variables at initial hepatectomy and recurrence.
Results Recurrent HCC was treated by repeat hepatectomy (Re-Hr, n = 29), radiofrequency ablation (RFA, n = 58), or transarterial chemoembolization (TAE, n = 38). Complete tumor control (CTC) by Re-He and RFA was selected for 70% of patients. RFA-treated patients had more tumors, smaller tumors, and poorer liver function at recurrence than the Re-Hr group. The overall 1-, 3-, and 5-year post-recurrence survival rates (SR) were 93.1, 66.8, 58.1%; 94.7, 75.1, 48.3%; and 80.1, 22.5, 0%, respectively, in the Re-Hr, RFA, and TAE groups. The SR was better for Re-Hr and RFA than for TAE (p < 0.0001). Outcomes were similar in Re-Hr and RFA, regardless of recurrent tumor size. Multivariate analysis identified Child-Pugh grade B, AFP >= 100 ng/ml at recurrence, recurrent tumor size >= 3 cm, tumor number >= 3, and CTC as significant prognostic factors for overall post-recurrence survival. A scoring system using 1 point for each patient-background factor provided a well-categorized predictive model. The overall 3-/5-year post-recurrence SRs were 83.1/59.3%, 64.1/41.9%, 42.0/18.0%, and 13.6/0% at risk number (R) R0, R1, R2, and R3/4, respectively (p < 0.05).
Conclusions Significant prognostic factors for intrahepatic recurrent HCC are poor hepatic reserve, AFP, recurrent tumor size and number, and CTC. Selection of treatment modality for intrahepatic recurrence requires the clinician to be mindful of the predictive factors and to control tumors aggressively by adequate treatment, selected by balancing various conditions.

A phase I clinical trial was conducted to determine the clinical safety of Telomelysin, a human telomerase reverse transcriptase (hTERT) promoter driven modified oncolytic adenovirus, in patients with advanced solid tumors. A single intratumoral injection (IT) of Telomelysin was administered to three cohorts of patients (1 x 10(10), 1 x 10(11), 1 x 10(12) viral particles). Safety, response and pharmacodynamics were evaluated. Sixteen patients with a variety of solid tumors were enrolled. IT of Telomelysin was well tolerated at all dose levels. Common grade 1 and 2 toxicities included injection site reactions (pain, induration) and systemic reactions (fever, chills). hTERT expression was demonstrated at biopsy in 9 of 12 patients. Viral DNA was transiently detected in plasma in 13 of 16 patients. Viral DNA was detectable in four patients in plasma or sputum at day 7 and 14 post-treatment despite below detectable levels at 24 h, suggesting viral replication. One patient had a partial response of the injected malignant lesion. Seven patients fulfilled Response Evaluation Criteria in Solid Tumors (RECIST) definition for stable disease at day 56 after treatment. Telomelysin was well tolerated. Evidence of antitumor activity was suggested.

Despite tremendous development in chemotherapy for ovarian cancer over the past few decades, the prognosis of advanced cases with massive peritoneal dissemination is still unsatisfactory, and novel treatment modalities that can combine with chemotherapy are urgently needed. We recently developed virotherapy for solid tumors using telomerase-specific replication-selective adenoviruses (Telomelysin: OBP-301), in which the human telomerase reverse transcriptase (hTERT) gene promoter has been inserted to direct tumor-specific E1 gene expression. In this study, we investigated the anti-tumor effects of OBP-301, combined with cisplatin (CDDP), on ovarian cancer cells. In vitro treatment of SKOV3 cells with OBP-301 at a multiplicity of infection (MOI) of 0.01-100 induced significant cell death in a dose-dependent manner, with moderate cytotoxicity at an MOI of 1-10 and maximal cytotoxicity at an MOI of 100. In contrast, OBP-301 treatment of normal human cells showed no significant cell death at an MOI of 1- 10 and exhibited modest cytotoxicity at an MOI of 100. The effects of low-dose CDDP at 0.5-1 mu M, which induced only 20% cell death, were significantly augmented by combination with OBP-301 at an MOI of 1- 10, finally achieving 40% cell death. Such enhancement of CDDP sensitivity was also observed in CDDP-resistant ovarian cancer cells. The combinatorial effects were further tested using a xenograft mouse model of SKOV3 with peritoneal dissemination. After intraperitoneal administration of OBP-301, we confirmed that injected OBP-301 fused with the green fluorescent protein (GFP) gene (OBP-401) was preferentially localized to peritoneal disseminations, as determined by fluorescence imaging. Treatment of mice with CDDP at low dose (0.5 mg kg(-1)) had modest effects, showing a 10% decrease in disseminations, whereas combination with intraperitoneal administration of OBP-301 at an MOI of 10 led to enhanced effects, achieving an approximately 80% decrease in disseminations. Kaplan-Meier analysis showed improved overall survival of mice treated with CDDP plus OBP-301 compared with CDDP alone. These findings support the therapeutic potential of intraperitoneal administration of OBP-301 to sensitize ovarian cancer cells to CDDP.

We previously reported that telomerase-specific replication-component adenovirous, Telomelysin (OBP-301) has cytotoxic activity to the YCUT892, KCCT873, KCCT891, KCCL871, YCUM862, HN12, and KCCOR891 cell lines in vitro, and investigated the association between cytotoxic activity and adenoviral receptor expression. In this study, we evaluated the most appropriate way to administer telomelysin (OBP-301) in the treatment of squamous cell carcinoma of the head and neck (SCCHN), and assessed the effect of OBP-301 in large subcutaneous KCCT873 human SCCHN tumors in immunodeficient mice. We also compared antitumor responses following three intratumoral (i.t.) injections of OBP-301 given daily, every 2 days or weekly. To investigate the mechanism of the antitumor effect, we evaluated cellular infiltration in treated tumors. OBP-301 showed remarkable antitumor activity against large KCCT873 tumors, and three treatment schedules produced similar antitumor effects. The weekly regimen also significantly reduced the growth of large tumors. Immunochemistry revealed that macrophages, but not natural killer cells, were responsible for tumor regression. A regimen of three weekly injections of OBP-301 has remarkable antitumor effects against large KCCT873 tumors. These results may provide a new platform for treating patients with localized SCCHN.

We previously constructed telomerase-dependent, replication-selective adenoviruses OBP-301 (Telomelysin) and OBP-401 [Telomelysin-green fluorescent protein (GFP); TelomeScan], the replication of which is regulated by the human telomerase reverse transcriptase promoter. By intratumoral injection, these viruses could replicate within the primary tumor and subsequent lymph node metastasis. The aim of the present study was to evaluate the possibility of systemic administration of these telomerase-dependent adenoviruses. We assessed the antitumor efficacy of OBP-301 and the ability of OBP-401 to deliver GFP in hepatocellular carcinoma (HCC) and metastatic colon cancer nude mouse models. We showed that i.v. administration of OBP-301 significantly inhibited colon cancer liver metastases and orthotopically implanted HCC. Further, we showed that OBP-401 could visualize liver metastases by tumor-specific expression of the GFP gene after portal venous or i.v. administration. Thus, systemic administration of these adenoviral vectors should have clinical potential to treat and detect liver metastasis and HCC. [Mol Cancer Ther 2009;8(11):3001-8]

The presence of circulating tumor cells (CTCs) in the peripheral blood is associated with short survival, making the detection of CTCs clinically useful as a prognostic factor of disease outcome and/or a surrogate marker of treatment response. Recent technical advances in immunocytometric analysis and quantitative real-time PCR have made it possible to detect a few CTCs in the blood; however, there is no sensitive assay to specifically detect viable CTCs. Here, we report what we believe to be a new approach to visually detect live human CTCs among millions of peripheral blood leukocytes, using a telomerase-specific replication-selective adenovirus expressing GFP. First, we constructed a GFP-expressing attenuated adenovirus, in which the telomerase promoter regulates viral replication (OBP-401; TelomeScan). We then used OBP-401 to establish a simple ex vivo method that was able to detect viable human CTCs in the peripheral blood. The detection method involved a 3-step procedure, including the lysis of rbc, the subsequent addition of OBP-401 to the cell pellets, and an automated scan using fluorescence microscopy. OBP-401 infection increased the signal-to-background ratio as a tumor-specific probe, because the fluorescent signal was amplified only in viable, infected human tumor cells, by viral replication. This GFP-expressing virus-based method is remarkably simple and allows precise enumeration of CTCs.

Cancer surgery requires the complete and precise identification of malignant tissue margins including the smallest disseminated lesions. Internal green fluorescent protein (GFP) fluorescence can intensely illuminate even single cells but requires GFP sequence transcription within the cell. Introducing and selectively activating the GFP gene in malignant tissue in vivo is made possible by the development of OBP-401, a telomerase-dependent, replication-competent adenovirus expressing GFP. This potentially powerful adjunct to surgical navigation was demonstrated in 2 nude mouse models that represent difficult surgical challenges-the resection of widely disseminated cancer. HCT-116, a model of intraperitoneal disseminated human colon cancer, was labeled by virus injection into the peritoneal cavity. A549, a model of pleural dissemination of human lung cancer, was labeled by virus administered into the pleural cavity. Only the malignant tissue fluoresced brightly in both models. In the intraperitoneal model of disseminated cancer, fluorescence-guided surgery enabled resection of all tumor nodules labeled with GFP by OBP-401. The data in this report suggest that adenoviral-GFP labeling tumors in patients can enable fluorescence-guided surgical navigation.

Cytological cancer screening that targets genetic or epigenetic abnormalities may be a viable alternative to morphological screening. Detecting cancer cells by specific genetic markers helps their easy detection in cytological samples. We recently established the telomerase-specific replication-selective adenovirus OBP-401, in which the human telomerase reverse transcriptase (hTERT) gene promoter has been inserted upstream of the El genes, and in which the green fluorescent protein (GFP) gene is driven by the CMV promoter. This virus selectively replicates only in telomerase-positive cells, expressing GFP, and therefore may be a toot for cancer screening. In the present study, we first confirmed that cytological samples can easily be infected with OBP-401, allowing visualization of GFP-positive cells under fluorescent microscopy 24 h after infection. After 32 cytological samples from patients with cervical, endometrial or ovarian cancers were infected with OBP-401, GFP signals were detected in 31 (96%) of the samples. However, some normal endometrial scrapings exhibited GFP-signals, possibly due to endometrial glandular cells with constitutive telomerase activity. The ability of OBP-401 to enrich cancer cells was then tested. Cytological samples containing cervical or endometrial cancer cells were infected with OBP-401, and GFP-positive cells were sorted by flow cytometry; DNA was extracted from the GFP-positive cells. Direct DNA sequencing or methylation-specific PCR identified cancer-derived mutations or hypermethylations of tumor suppressor genes more efficiently than analyses using crude cytological samples. Thus, OBP-401-Z, based sorting of GFP-positive cells successfully enriched cancer cells, allowing efficient detection of genetic or epigenetic abnormalities in cytological samples.

We constructed a replication-competent oncolytic adenovirus, OBP-301 (Telomelysin), in which human telomerase reverse transcriptase (hTERT) promoter drives E1 genes. OBP-301 is currently being used in a phase-I clinical trial for various types of tumors. Under such conditions, anti-adenoviral agents should be available for safety use against OBP-301 since any adenoviral viremia could cause severe adverse effects. Cidofovir (CDV) is an acyclic nucleoside phosphonate that has a broad antiviral activity against DNA viruses. Here, we examined the antiviral effects of CDV against OBP-301. The in vitro cytopathic effects of OBP-301 were suppressed by CDV. Moreover, CDV decreased the adenoviral E1A gene copy number after OBP-301 infection. These results suggest that CDV is a potentially useful antiviral agent for OBP-301.

A phase I dose-escalation study of telomerase-specific oncolytic adenovirus, OBP-301 (Telomelysin), is now under way in the United States to assess feasibility and to characterize its pharmacokinetics in patients with advanced solid tumors. The present preclinical study investigates whether OBP-301 and a chemotherapeutic agent that is commonly used for lung cancer treatment, gemcitabine, are able to enhance antitumor effects in vitro and in vivo. The antitumor effects of OBP-301 infection and gemcitabine were evaluated by 2,3-bis[2-methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxanilide inner salt assay. In vivo antitumor effects of intratumoral injection of OBP-301 in combination with systemic administration of gemcitabine were assessed on nu/nu mice s.c. xenografted with human lung tumors. OBP-301 infection combined with gemcitabine resulted in very potent synergistic cytotoxicity in human lung cancer cells. The three human lung cancer cell lines treated with OBP-301 for 24 hours tended to accumulate in S phase compared with controls. The proportion of cells in S phase increased from 43.85% to 56.41% in H460 cells, from 46.72% to 67.09% in H322 cells, and from 38.22% to 57.67% in H358 cells. Intratumoral injection of OBP-301 combined with systemic administration of gemcitabine showed therapeutic synergism in human lung tumor xenografts. Our data suggest that the combination of OBP-301 and gemcitabine enhances the antitumor effects against human lung cancer. We also found that the synergistic mechanism may be due to OBP-301-mediated cell cycle accumulation in S phase. These results have important implications for the treatment of human lung cancer.

Purpose: Long-term outcomes of patients with squamous cell carcinoma of the head and neck (SCCHN) remain unsatisfactory despite advances in combination of treatment modalities. SCCHN is characterized by locoregional spread and it is clinically accessible, making it an attractive target for intratumoral biological therapies.
Experimental Design: OBP-301 is a type 5 adenovirus that contains the replication cassette in which the human telomerase reverse transcriptase promoter drives expression of the E1 genes. OBP-401 contained the replication cassette and the green fluorescent protein (GFP) gene. The antitumor effects of OBP-301 were evaluated in vitro by the sodium 30-[1-(phenylaminocarbonyl) -3,4-tetrazolium]-bis(4-methoxy-6-nitro)benzene sulfonic acid hydrate assay and in vivo in an orthotopic xenograft model. Virus spread into the lymphatics was also orthotopically assessed by using OBP-401.
Results: Intratumoral injection of OBP-301 resulted in the shrinkage of human SCCHN tumors orthotopically implanted into the tongues of BALB/c nu/nu mice and significantly recovered weight loss by enabling oral ingestion. The levels of GFP expression following ex vivo infection of OBP-401 may be of value as a positive predictive marker for the outcome of telomerase-specific virotherapy. Moreover, whole-body fluorescent imaging revealed that intratumorally injected OBP-401 Could visualize the metastatic lymph nodes, indicating the ability of the virus to traffic to the regional lymphatic area and to selectively replicate in neoplastic lesions, resulting in GFP expression and cell death in metastatic lymph nodes.
Conclusions: These results illustrate the potential of telomerase-specific oncolytic viruses for a novel therapeutic and diagnostic approach, termed theranostics, for human SCCHN.

Telomerase-specific replication-competent adenovirus, Telomelysin (OBP-301), has a human telomerase reverse transcriptase promoter that regulates viral replication and efficiently kills human cancer cells. The objectives of this study are to examine the effects of OBP-301 in squamous cell carcinoma of the head and neck cells in vitro and in xenografted animals in vivo. OBP-301 was found to be cytotoxic to the YCUT892, KCCT873, KCCT891, KCCL871, YCUM862, HN12, and KCCOR891 cell lines in vitro. However, the level of cytotoxicity is not correlated with the expression levels of adenoviral receptors, which may be required for adenoviral infection in squamous cell carcinoma of the head and neck cells. OBP-301 shows remarkable antitumor activity against established s.c. KCCT873 tumors in immunodeficient animals in a dose-dependent manner. In addition, no significant toxicity was observed in animals receiving treatment. These results suggest that OBP-301 is a novel therapeutic agent with promise for the treatment of human head and neck cancers. [Mol Cancer Ther 2009(1): 171 - 7]

Oncolytic adenoviruses are a promising tool in cancer therapy. In this study, we characterized the role of autophagy in oncolytic adenovirus-induced therapeutic effects. OBP-405, an oncolytic adenovirus regulated by the human telomerase reverse transcriptase promoter (hTERT-Ad, OBP-301) with a tropism modification (RGD) exhibited a strong antitumor effect on glioblastoma cells. When autophagy was inhibited pharmacologically, the cytotoxicity of OBP-405 was attenuated. In addition, autophagy-deficient Atg5 mouse embryonic fibroblasts (MEFs) were less sensitive than wild-type MEFs to OBP-405. These findings indicate that OBP-405-induced autophagy is a cell killing effect. Moreover, autophagy-inducing therapies (temozolomide and rapamycin) synergistically sensitized tumor cells to OBP-405 by stimulating the autophagic pathway without altering OBP-405 replication. Mice harboring intracranial tumors treated with OBP-405 and temozolomide survived significantly longer than those treated with temozolomide alone, and mice treated with OBP-405 and the rapamycin analog RAD001 survived significantly longer than those treated with RAD001 alone. The observation that autophagy inducers increase OBP-405 antitumor activity suggests a novel strategy for treating patients with glioblastoma.

Telomerase activation is a critical step for human carcinogenesis through the maintenance of telomeres, but the activation mechanism during carcinogenesis remains unclear. Transcriptional regulation of the human telomerase reverse transcriptase (hTERT) gene is the major mechanism for cancer-specific activation of telomerase, and a number of factors have been identified to directly or indirectly regulate the hTERT promoter, including cellular transcriptional activators (c-Myc, Sp1, HIF-1, AP2, ER, Ets, etc.) as well as the repressors, most of which comprise tumor suppressor gene products, such as p53, WT1, and Menin. Nevertheless, none of them can clearly account for the cancer specificity of hTERT expression. The chromatin structure via the DNA methylation or modulation of nucleosome histones has recently been suggested to be important for regulation of the hTERT promoter. DNA unmethylation or histone methylation around the transcription start site of the hTERT promoter triggers the recruitment of histone acetyltransferase (HAT) activity, allowing hTERT transcription. These facts prompted us to apply these regulatory mechanisms to cancer diagnostics and therapeutics. Telomerase-specific replicative adenovirus (Telomelysin, OBP-301), in which E1A and E1B genes are driven by the hTERT promoter, has been developed as an oncolytic virus that replicates specifically in cancer cells and causes cell death via viral toxicity. Direct administration of Telomelysin was proved to effectively eradicate solid tumors in vivo, without apparent adverse effects. Clinical trials using Telomelysin for cancer patients with progressive stages are currently ongoing. Furthermore, we incorporated green fluorescent protein gene (GFP) into Telomelysin (TelomeScan, OBP-401). Administration of TelomeScan into the primary tumor enabled the visualization of cancer cells under the cooled charged-coupled device (CCD) camera, not only in primary tumors but also the metastatic foci. This technology can be applied to intraoperative imaging of metastatic lymphnodes. Thus, we found novel tools for cancer diagnostics and therapeutics by utilizing the hTERT promoter.

Cancer gene therapy and oncolytic virotherapy have been studied extensively. However, their clinical application is hampered by their weak anticancer activity. We previously constructed a replicating adenovirus (OBP-301, Telomelysin), in which the human telomerase reverse transcriptase (hTERT) promoter drives expression of the adenoviral El genes, and causes selective lysis of human cancer cells. We hypothesized that combination adenoviral therapy containing OBP-301 and a nonreplicating adenovirus expressing the proapoptotic Bax gene could overcome the weakness and augment the anticancer efficacy of each modality. Combination treatment resulted in marked Bax protein expression and enhanced efficacy in in vitro cell viability assay, when compared with either single treatment. However, combination treatment was not as effective in suppressing both subcutaneous and pleural disseminated tumors compared with OBP-301 treatment alone. Further investigation revealed that combination treatment resulted in suppressed EIA protein expression associated with reduced viral replication. Our results suggest that Bax gene therapy in combination with oncolytic adenovirotherapy potentially augments their antitumor activity, but further improvements may be required to maximize the combinatorial effect in vivo, for the Bax gene expression to avoid interference with production of the oncolytic virus.

We previously constructed OBP-301 ( Telomelysin, a telomerase-specific replication-competent adenovirus with human telomerase reverse transcriptase ( hTERT) promoter), which showed a strong anticancer effect by inducing cell lysis of human non-small cell lung cancer and colorectal cancer cells. To investigate the utility of OBP-301 for prostate cancer treatment, we herein evaluate the cell killing and antitumor effects. First, in vitro hTERT-specific adenovirus transduction in human prostate cancer cells ( LNCaP, PC3, DU145) was confirmed using OBP-401 ( Telomelysin-green fluorescent protein ( GFP)). There was no detectable GFP transduction in the human prostate normal cells ( PrEC, PrSC). Consistently, the cell-killing effect of OBP-301 was observed only in the cancer cells. Second, using an in vivo subcutaneous LNCaP tumor model in nude mice, we demonstrated that three intratumoral OBP-301 injections ( 10(7) PFU per tumor x 3 days) were sufficient to eradicate the detectable LNCaP prostate tumor. We also demonstrated that the ispilateral treatment with OBP-301 significantly suppressed contralateral LNCaP tumor growth in both sides of the tumor model. Histological and immunohistochemical analyses revealed diffuse oncolytic degeneration and adenoviral E1A protein expression in both sides of the tumors. Therefore, in situ OBP-301 administration could be a promising therapeutic strategy against prostate cancer and its metastatic lesions.

Dendritic cells ( DCs) are the most potent antigen-presenting cells and acquire cellular antigens and danger signals from dying cells to initiate antitumor immune responses via direct cell- to- cell interaction and cytokine production. The optimal forms of tumor cell death for priming DCs for the release of danger signals are not fully understood. OBP- 301 ( Telomelysin) is a telomerase-specific replication- competent adenovirus that induces selective E1 expression and exclusively kills human cancer cells. Here, we show that OBP- 301 replication produced the endogenous danger signaling molecule, uric acid, in infected human tumor cells, which in turn stimulated DCs to produce interferon-gamma ( IFN-gamma) and interleukin 12 ( IL- 12). Subsequently, IFN-gamma release upregulated the endogenous expression of the proteasome activator PA28 in tumor cells and resulted in the induction of cytotoxic T- lymphocytes. Our data suggest that virus- mediated oncolysis might be the effective stimulus for immature DCs to induce specific activity against human cancer cells.

The use of replication-selective tumor-specific viruses represents a novel approach for the treatment of neoplastic disease. We constructed an attenuated adenovirus, telomerase-specific replication-selective adenovirus (TRAD), in which the human telomerase reverse transcriptase promoter element drives the expression of the E1A and E1B genes linked with an internal ribosome entry site (IRES). Forty-eight hours after TRAD infection at a multiplicity of infection of 1.0, the cell viability of H1299 human lung cancer cells was consistently less than 50% and therefore this procedure could be used as a potency assay to assess the biological activity of TRAD. We also established a quantitative real-time polymerase chain reaction (PCR) analysis with consensus primers for either the adenovirus E1A or IRES sequence. The linear ranges of quantitation with E1A and IRES primers were 10(3)-10(8) and 10(2)-10(8) plaque-forming units/mL in the plasma, respectively. The PCR analysis demonstrated that the levels of E1A in normal tissues were more than 10(3) lower than in the tumors of A549 human lung tumor xenografts in nu/n mu mice at 28 days after intratumoral injection. Our results suggest that the cell-killing assay against H1299 cells and real-time PCR can be used to assess the biological activity and biodistribution of TRAD in clinical trials.

Replication-selective tumor-specific viruses present a novel approach for treatment of neoplastic disease. These vectors are designed to induce virus-mediated lysis of tumor cells after selective viral propagation within the tumor. Telomerase activation is considered to be a critical step in carcinogenesis and its activity correlates closely with human telomerase reverse transcriptase (hTERT) expression. Since only tumor cells that express telomerase activity would activate this promoter, the hTERT proximal promoter allows for preferential expression of viral genes in tumor cells, leading to selective viral replication. We constructed an attenuated adenovirus 5 vector (Telomelysin, OBP-301), in which the hTERT promoter element drives expression of E1A and E1B genes linked with an internal ribosome entry site (IRES). Telomelysin replicated efficiently and induced marked cell killing in a panel of human cancer cell lines, whereas replication as well as cytotoxicity was highly attenuated in normal human cells lacking telomerase activity. We further modified the E3 region of OBP-301 to contain green fluorescent protein (GFP) gene for monitoring viral replication (TelomeScan, OBP-401). When TelomeScan was intratumorally injected into human tumors orthotopically implanted into the rectum in mice, para-aortic lymph node metastasis could be visualized at laparotomy under a three-chip color cooled charged-coupled device camera. Our results indicate that TelomeScan causes viral spread into the regional lymphatic area and selectively replicates in neoplastic lesions, resulting in GFP expression in metastatic lymph nodes. This article reviews recent highlights in this rapidly evolving field: cancer therapeutic and cancer diagnostic approaches using the telomerase-specific oncolytic adenoviruses.

hSNF5/Inil is a core component of the SWI/SNF complex and the gene is frequently mutated in aggressive pediatric rhabdoid tumors. Mechanisms of the malignant transformation, however, remain poorly understood. We analyzed HeLa cells treated with siRNA to the hSNF5/Inil mRNA. The resulting efficient and long-term suppression caused characteristic cell enlargement, cell cycle arrest in G1 phase, and subsequent modest apoptosis. Gene expression profiling of the hSNF5-down-regulated cells by cDNA microarray analysis revealed that a limited number of p53-responsive genes, especially p21, were up-regulated. The p53 protein level was also greatly enhanced, suggesting that loss of hSNF5/Inil induces a p53 signaling pathway irrelevant to the chk1/2 phosphorylation pathway. Some rhabdoid tumors with very low or no ARF expression were induced to undergo cell enlargement, growth arrest, and, in one case, apoptosis by ectopic expression of the p14ARF protein. These results may in part account for molecular mechanisms of rhabdoid tumor formation. (c) 2007 Elsevier Inc. All rights reserved.

Biphasic pulmonary blastoma is a rare lung tumor with epithelia[ and mesenchymal components. Genetic alterations in this tumor are largely unknown, except for the presence of beta-catenin and p53 mutations and the absence of KRAS mutation. To understand the molecular process of histogenesis of this tumor, a whole genome allelic imbalance (Al) scanning using a high-resolution single nucleotide polymorphism array as well as mutational analysis of the p53, EGFR, KRAS and beta-catenin genes were performed against the epithelial and mesenchymal components in the primary tumor and a metastatic tumor in a case of pulmonary blastoma. Al at chromosome regions 14q24-q32 and 17p11-p13 and beta-catenin mutation were commonly detected in all tumors. On the other hand, Al at chromosome regions 3p11-p14 and 9p21-p24 and p53 mutation were detected only in the mesenchymal component in the primary tumor but not in the epithelial component in the primary tumor and the brain metastasis. Likewise, Al at chromosome regions 6p24-p25 and 6q14-q27 was detected in the epithelial. component in the primary tumor and the brain metastasis but not in the mesenchymal component in the primary tumor. Furthermore, the genetic alterations detected in the metastatic tumor were completely the same as those in the epithelial component in the primary tumor, indicating that a tumor cell(s) in the epithelial component in the primary tumor selectively metastasized to the brain. These results indicate that this biphasic tumor is of monoclonal origin and the phenotypic heterogeneity of the tumor is due to the differences in the accumulated genetic alterations in each component of the tumor.

The aim of the present study was to investigate the safety and immunological responses of personalized peptide vaccination in combination with oral administration of a 5-fluorouracil derivative (TS-1) in advanced gastric or colorectal carcinoma patients. Eleven patients (four with gastric cancer and seven with colorectal cancer) who failed to improve by prior TS-1-based chemotherapies were enrolled in this study. Peptides to be administered to patients were determined based on the presence of peptide-specific cytotoxic T lymphocyte (CTL) precursors in peripheral blood mononuclear cells and peptide-specific IgG in the plasma of cancer patients. Patients were vaccinated with peptides (a maximum of four) biweekly in combination with or without three different doses of TS-1 (20, 40 and 80 mg/m(2)/day). Although grade 3 toxicity, including anemia (one patient) and neutropenia (one patient) were observed, the combination therapy was generally well tolerated. An increase in peptide-specific IgG after the sixth vaccination was observed in the vast majority of patients irrespective of the dose of TS-1 used. In contrast, an increase in peptide-specific interferon-gamma production by CTL was most evident in patients who were administered the highest dose of TS-1. Furthermore, in the patients who received 80 mg/m(2)/day TS-1, CTL-mediated cytotoxicity against cancer cells was maintained at the prevaccination level. These results indicate that administration of the standard dose (80 mg/m(2)/day) of TS-1 in combination with a personalized peptide vaccination does not necessarily impede immunological responses in cancer patients, and could actually maintain or augment them.

Background. During perioperative management of patients with gastrointestinal cancer complicated by diabetes mellitus, adequate alimentation is required, but we often face difficulties associated with hyperglycemia and other accompanying complications. Recently, we investigated the effects of a novel palatinose based enteral formula (MHN-01) in suppressing post-prandial hyperglycemia and improving lipid metabolism in experimental animals and perioperative management of patients with esophageal cancer complicated by diabetes mellitus.
Materials and methods. We gave normal rats and rats with type 2 diabetes mellitus a single oral dose of fluid diet, and analyzed comparatively the time course of blood glucose level in each group until 3 h after the dose. In both the normal rat group and the type 2 diabetes group, peak blood glucose level after the MHN-01 dose was significantly lower than after a dose of ordinary fluid diet and was comparable to the peak level after a dose of a fluid diet rich in MUFA (monounsaturated fatty acid). We allowed normal mice free access to fluid diet for 43 days, and measured their body fat levels. Fat accumulation was significantly lower in mice given MHN-01 than in mice given ordinary fluid diet. We also analyzed the respiratory quotient and resting energy expenditure of normal Sprague-Dawley rats fed by MHN-01 or an ordinary fluid diet. The respiratory quotient of the MHN-01 group was significantly lower than the ordinary fluid group, although the resting energy expenditure of both groups was almost the same level. The effect of MHN-01 was estimated to be based on improvement of lipid metabolism.
Results. Between 2003 and 2005, among 164 patients who underwent radical thoracic esophagectomy and/or reconstruction for esophageal carcinoma at Okayama University Hospital, nine patients (5.5%) were diagnosed with diabetes mellitus in preoperative screening and were treated with MHN-01. Clinical courses of two cases with severe status of diabetes mellitus were presented as successful case reports of MHN-01.
Conclusion. MHN-01 was very useful in perioperative management of patients complicated by diabetes mellitus, unable to ingest food p.o. such as esophageal cancer or other diseases. (c) 2007 Elsevier Inc. All rights reserved.

Replication-selective tumor-specific viruses present a novel approach for treatment of neoplastic disease. These vectors are designed to induce virus-mediated lysis of tumor cells after selective viral propagation within the tumor. For targeting cancer cells, there is a need for tissue- or cell-specific promoters that can express in diverse tumor types and are silent in normal cells. Recent advances in molecular biology have fostered remarkable insights into the molecular basis of neoplasm. Telomerase activation is considered to be a critical step in carcinogenesis and its activity correlates closely with human telomerase reverse transcriptase (hTERT) expression. Since only tumor cells that express telomerase activity would activate this promoter, the hTERT proximal promoter allows for preferential expression of viral genes in tumor cells, leading to selective viral replication. We constructed an attenuated adenovirus 5 vector (Telotnelysin, OBP-301), in which the hTERT promoter element drives expression of E1A and E1B genes linked with an internal ribosome entry site (IRES). Telomelysin replicated efficiently and induced marked cell killing in a panel of human cancer cell lines, whereas replication as well as cytotoxicity was highly attenuated in normal human cells lacking telomerase activity. Thus, the hTERT promoter confers competence for selective replication of Telomelysin in human cancer cells, an outcome that has important implications for the treatment of human cancers. This article reviews recent findings in this rapidly evolving field: cancer therapeutic and cancer diagnostic approaches using the hTERT promoter.

Purpose: Several models of cancer progression, including clonal evolution, parallel evolution, and same-gene models, have been proposed to date. The purpose of this study is to investigate the authenticity of these models by comparison of accumulated genetic alterations between primary and corresponding metastatic lung cancers.
Experimental Design: A whole-genome allelic imbalance scanning using a high-resolution single nucleotide polymorphism array and mutational analysis of the p53, EGFR, and KRAS genes were done on eight sets of primary and metastatic lung cancers. Based on the genotype data, the natural history of each case was deduced, and candidate metastasis suppressor loci were determined.
Results: Five to 20 chromosomal regions showed allelic imbalance in each tumor. Accumulated genetic alterations were similar between primary and corresponding metastatic tumors, and the majority (>67%) of genetic alterations detected in metastatic tumors was also detected in the corresponding primary tumors. On the other hand, in seven of the eight cases, there were genetic alterations accumulated only in metastatic tumors. Among these alterations, allelic imbalances at chromosome 11p15 and 11p11-p13 regions were the most frequent ones (4 of 8, 50%). Likewise, four cases showed genetic alterations detected only In primary tumors.
Conclusions: The natural history of each case indicated that the process of metastasis varies among cases, and that all three models are applicable to lung cancer progression. According to the clonal and parallel evolution models, it is possible that a metastasis suppressor gene(s) for lung cancer is present on chromosome 11p.

To determine the feasibility, safety, humoral immune response, and biological activity of multiple intratumoral injections of Ad5CMV-p53, and to characterize the pharmacokinetics of Ad5CMV-p53 in patients with advanced non-small cell lung cancer (NSCLC). Fifteen patients with histologically confirmed NSCLC and p53 mutations were enrolled into this phase I trial. Nine patients received escalating dose levels of Ad5CMV-p53 (1 × 109 to 1 × 1011 plaque-forming units[PFU]) as monotherapy once every 4 weeks. Six patients were treated on a 28-day schedule with Ad5CMV-p53 in combination with intravenous administration of cisplatin (80 mg/m2). Patients were monitored for toxicity, vector distribution, antibody formation, and tumor response. Fifteen patients received a total of 63 intratumoral injections of Ad5CMV-p53 without dose-limiting toxicity. The most common treatment-related toxicity was a transient fever. Specific p53 transgene expression was detected using reverse-transcriptase polymerase chain reaction in biopsied tumor tissues throughout the period of treatment despite of the presence of neutralizing anti-adenovirus antibody. Distribution studies revealed that the vector was detected in the gargle and plasma, but rarely in the urine. Thirteen of 15 patients were assessable for efficacy; one patient had a partial response (squamous cell carcinoma at the carina), 10 patients had stable disease, with three lasting ≥9 months, and 2 patients had progressive disease. Multiple courses of intratumoral Ad5CMV-p53 injection alone or in combination with intravenous administration of cisplatin were feasible and well tolerated in advanced NSCLC patients, and appeared to provide clinical benefit.

Currently available methods for detection of tumors in vivo such as computed tomography and magnetic resonance imaging are not specific for tumors. Here we describe a new approach for visualizing tumors whose fluorescence can be detected using telomerase-specific replication-competent adenovirus expressing green fluorescent protein (GFP) (OBP-401). OBP-401 contains the replication cassette, in which the human telomerase reverse transcriptase (hTERT) promoter drives expression of E1 genes, and the GFP gene for monitoring viral replication. When OBP-401 was intratumorally injected into HT29 tumors orthotopically implanted into the rectum in BALB/c nu/nu mice, para-aortic lymph node metastasis could be visualized at laparotomy under a three-chip color cooled charged-coupled device camera. Our results indicate that OBP-401 causes viral spread into the regional lymphatic area and selectively replicates in neoplastic lesions, resulting in GFP expression in metastatic lymph nodes. This technology is adaptable to detect lymph node metastasis in vivo as a preclinical model of surgical navigation.

We report a rare case of esophageal intramural pseudodiverticulosis with esophageal strictures. Barium esophagogram demonstrated multiple flask-shaped diverticula out of the esophageal wall with comprehensive luminal stenosis involving the proximal 8 cm and distal 4 cm of the esophagus. Chest computed tomographic scan demonstrated round wall thickening and several intramural gas collections of the proximal esophagus. Endoscopy revealed a fibrotic stricture and multiple small orifices of pseudodiverticula with mild inflammatory changes. Biopsy specimens showed active chronic inflammatory changes of the mucosa with candidiasis. Dysphagia improved dramatically with esophageal dilation. However, the tiny diverticula did not resolve after treatment.

Oncolytic adenoviruses are being developed as novel anticancer therapeutics and currently undergoing clinical trials. We previously demonstrated that telomerase-specific replication-competent adenovirus (Telomelysin: OBP-301), in which the human telomerase reverse transcriptase (hTERT) promoter regulates viral replication, efficiently killed human tumor cells. We further constructed OBP-401 (Telomelysin-GFP) that expresses the green fluorescent protein (GFP) reporter gene under the control of the cytomegalovirus promoter in the E3 region to monitor viral distribution. Here, we examined the feasibility of a single-agent therapy with OBP-401 as well as of combining OBP-401 with chemotherapeutic agents. Infection of OBP-401 alone or followed by the treatment of a chemotherapeutic drug, docetaxel (Taxotere), resulted in a profound in vitro cytotoxicity and GFP expression in various human cancer cell lines originating from different organs (lung, colon, esophagus, stomach, liver and prostate), although the magnitude of antitumor effect varied among the cell types. Other chemotherapeutic drugs such as vinorelbine (Navelbine) and SN38 (the potent active metabolite of irinotecan) combined with OBP-401 also inhibited the growth of human cancer cells. Quantitative real-time PCR analysis demonstrated that docetaxel did not affect viral replication. For in vivo evaluation, nu/nu mice xenografted with H1299 human lung tumor received intratumoral injection of OBP-401 and intraperitoneal administration of docetaxel. Analysis of growth of implanted tumors showed a significant, therapeutic synergism, although OBP-401 alone and docetaxel alone showed modest inhibition of tumor growth. Thus, OBP-401 in combination with docetaxel efficiently enhances the antitumor efficacy both in vitro and in vivo, and the outcome has important implications for tumor-specific oncolytic chemovirotherapies for human cancers.

Patients and Methods
Fifteen patients with histologically confirmed NSCLC and p53 mutations were enrolled onto this phase I trial. Nine patients received escalating dose levels of Ad5CMV-p53 (1 X 10(9) to 1 X 10(11) plaque-forming units) as monotherapy once every 4 weeks. Six patients were treated on a 28-day schedule with Ad5CMV-p53 in combination with intravenous administration of cisplatin (80 mg/m(2)). Patients were monitored for toxicity, vector distribution, antibody formation, and tumor response.

Conclusion
Multiple courses of intratumoral Ad5CMV-p53 injection alone or in combination with intravenous administration of cisplatin were feasible and well tolerated in advanced NSCLC patients, and appeared to provide clinical benefit.

Replication-competent oncolytic viruses are being developed for human cancer therapy. We previously reported that an attenuated adenovirus OBP-301 (Telomelysin), in which the human telomerase reverse transcriptase promoter element drives expression of EIA and El B genes linked with an internal ribosome entry site, could replicate in and causes selective lysis, of human cancer cells. Infection efficiency in target cancer cells is the most important factor that predicts the antitumor effects of OBP-301. The ob objectives of this study are to examine the effects of the histone deacetylase inhibitor FR901228 on the level of coxsackie and adenovirus receptor (CAR) expression and OBP-301-mediated oncolysis in human non-small cell lung cancer cell lines. Flow cytometric analysis revealed up-regulated CAR expression in A549 and H460 cells following treatment with 1 ng/ml of FR901228. which was associated with increased infection efficiency as confirmed by replication-deficient beta-galactosidase-expressing adenovirus vector. In contrast. neither CAR expression nor infection efficiency was affected by FR901228 in H1299 cells. To visualize and quantify viral replication in the presence of FR901228, we used 01311-401 (Telomelysin-GFP) that expresses the green fluorescent protein (GFP) reporter gene under the control of the cytomegalovirus promoter in the E3 region. Fluorescence microscopy and flow cytometry showed that FR901228 increased GFP expression in A549 and 11460 cells following OBP-401 infection in a dose-dependent manner, but this effect did not occur in H1299 cells. In addition. OBP-301 and FR901228 demonstrated a synergistic antitumor effect in A549 cells in vitro, as confirmed by isobologram analysis. Our data indicate that FR901228 preferentially increases adenovirus infectivity via up-regulation of CAR expression, leading to a profound oncolytic effect, which may have a significant impact on the outcome of adenovirus-based oncolytic virotherapy.

The EGF (epidermal growth factor) receptor-tyrosine kinase inhibitor ZD1839 (Getitinib, 'Iressa') blocks the cell signaling pathways involved in cell proliferation, survival, and angiogenesis in various cancer cells. TNF-related death apoptosis inducing ligand (TRAIL) acts as an anticancer agent. We investigated the antitumor effects of ZD-1839 alone or in combination with TRAIL against human esophageal squamous cell cancer (ESCC) lines. Although all ESCC cells expressed EGF receptor at a protein level, the effect of ZD1839 on cell growth did not correlate with the level of EGFR expression and phosphorylation of EGF receptor protein in ESCC lines. ZD1839 caused a dose-dependent growth arrest at GO-G, phase associated with increased p27 expression. As TE8 cells are resistant to TRAIL, we tested whether ZD1839 combined with TRAIL induced apoptosis of TE8 cells via the inhibition of EGF receptor signaling by ZD1839. ZD1839 inhibited the phosphorylation of Akt, and enhanced TRAIL-induced apoptosis via activation of caspase-3 and caspase-9, and inactivation of Bcl-xL. Our results indicated that ZD1839 has anti-cancer properties against human esophageal cancer cells. ZD1839 also augmented the anti-cancer activity of TRAIL, even in TRAIL-resistant tumors. These results suggest that treatment with ZD1839 and TRAIL may have potential in the treatment of ESCC patients. (c) 2005 Federation of European Biochemical Societies. Published by Elsevier B.V.

The tumor suppressor p53 functions as a transcriptional activator to induce cell cycle arrest and apoptosis in response to DNA damage. Although p53 was also shown to mediate apoptosis in a manner independent of its transactivation activity, the mechanism and conditions that trigger such cell death have remained largely unknown. We have now shown that inhibition of RNA polymerase II-mediated transcription by α-amanitin or RNA interference induced p53-dependent apoptosis. Inhibition of pol II-mediated transcription resulted in down-regulation of p21(Cip1), which was caused by both transcriptional suppression and protein degradation, despite eliciting p53 accumulation, allowing the cells to progress into S phase and then to undergo apoptosis. This cell death did not require the transcription of p53 target genes and was preceded by translocation of the accumulated p53 to mitochondria. Our data thus suggested that blockade of pol II-mediated transcription induced p53 accumulation in mitochondria and was the critical factor for eliciting p53-dependent but transcription-independent apoptosis.

Replication-competent oncolytic viruses are being developed for human cancer therapy. We previously reported that an attenuated adenovirus (OBP-301, 'Telomelysin'), in which the hTERT promoter element drives expression of E1A and E1B genes linked with an IRES, could replicate in cancer cells, and causes selective lysis of cancer cells. We further constructed OBP-405 ('Telomelysin-RGD') that contains an RGD motif in the HI loop of the fiber knob. We examined whether OBP-405 could be effective in overcoming the limitations of OBP-301, specifically their inefficient infection into cells lacking the primary receptor, the coxsackievirus and adenovirus receptor ( CAR). By flow cytometric analysis, H1299 ( lung) and SW620 ( colorectal) tumor cells showed high levels of CAR expression, whereas LN444 ( glioblastoma), LNZ308 ( glioblastoma), and H1299-R5 ( lung) tumor cells were negative for CAR expression. A quantitative realtime PCR analysis demonstrated that fiber-modified OBP-405 infected more efficiently than OBP-301, although the intracellular replication rate of both viruses was consistent. The comparative antitumor effect of fiber-modified OBP-405 and unmodified OBP-301 for human cancer cells was evaluated in vitro by XTT assay as well as in vivo by using athymic mice carrying xenografts. OBP-405 had a profound oncolytic effect on human cancer cell lines compared to OBP-301, in particular on cells with low CAR expression. Intratumoral injection of 107 plaque-forming units of OBP-405 into CAR-negative H1299-R5 lung tumor xenografts in nu/nu mice resulted in a significant inhibition of tumor growth and long-term survival in all treated mice. Moreover, selective replication of OBP-405 in the distant, uninjected H1299-R5 tumors was demonstrated. Our results suggest that fiber-modified replication-competent adenovirus OBP-405 exhibits a broad target range by increasing infection efficiency, an outcome that has important implications for the treatment of human cancers.

Aims: This study assessed the techniques of the free jejunal graft for the reconstruction of hypopharynx or cervical esophagus and discussed the main aspects related to those procedures. Methods and results: By using free jejunal grafts, we reconstructed 54 hypopharyngeal and cervical esophageal cancers. In this study, 23 out of 54 patients had a malignant tumor located in the hypopharynx and 31 in the cervical esophagus (27 primary cases and four secondary cases). Despite the multi-step and time-consuming procedure, we did not incur any trans-operative complication. Furthermore, we undertook the larynx preserving cervical esophagectomy and free jejunal graft reconstruction in six patients with cervical esophageal cancer, and those patients acquired a good quality of life. Conclusion: For the reconstruction of hypopharynx or cervical esophagus, the free jejunal graft is a very useful technique and improves the patient's quality of life.

Currently available methods for detection of tumors in vivo such as X-ray, computed tomography, and ultrasonography are noninvasive and have been well studied
the images, however, are not specific for tumors. Direct optical imaging of tumor cells in vivo that can clearly distinguish them from surrounding normal tissues may be clinically useful. Here, we describe a new approach to visualizing tumors whose fluorescence can be detected using tumor-specific replication-competent adenovirus (OBP-301, Telomelysin) in combination with Ad-GFP, a replication-deficient adenovirus expressing green fluorescent protein (GFP). Human telomerase reverse transcriptase is the catalytic subunit of telomerase, which is highly active in cancer cells but quiescent in most normal somatic cells. We constructed an adenovirus 5 vector in which the human telomerase reverse transcriptase promoter element drives expression of E1A and E1B genes linked with an internal ribosome entry site and showed that OBP-301 replicated efficiently in human cancer cells, but not in normal cells such as human fibroblasts. When the human lung and colon cancer cell lines were infected with Ad-GFP at a low multiplicity of infection, GFP expression could not be detected under a fluorescence microscope
in the presence of OBP-301, however, Ad-GFP replicated in these tumor cells and showed strong green signals. In contrast, coinfection with OBP-301 and Ad-GFP did not show any signals in normal cells such as fibroblasts and vascular endothelial cells. We also found that established subcutaneous tumors could be visualized after intratumoral injection of OBP-301 and Ad-GFP. A549 human lung tumors and SW620 human colon tumors transplanted into BALB/c nu/nu mice were intratumorally injected with 8 × 105 plaque-forming units of Ad-GFP in combination with 8 × 106 plaque-forming units of OBP-301. Within 3 days of treatment, the fluorescence of the expressed GFP became visible by a three-chip color cooled charged-coupled device camera in these tumors, whereas intratumoral injection of Ad-GFP alone could not induce GFP fluorescence. Moreover, intrathoracic administration of Ad-GFP and OBP-301 could visualize disseminated A549 tumor nodules in mice after intrathoracic implantation. Our results indicate that intratumoral or intrathoracic injection of Ad-GFP in combination with OBP-301 might be a useful diagnostic method that provides a foundation for future clinical application.

Purpose: Dendritic cells (DCs) are attractive effectors for cancer immunotherapy because of their potential to function as professional antigen-presenting cells for initiating cellular immune responses. The tumor suppressor gene p53 is pivotal in the regulation of apoptosis, and ∼50% of human malignancies exhibit mutation and aberrant expression of p53. We investigated the antitumor effect of intratumoral administration of bone marrow-derived dendritic cells transduced with wild-type p53 gene. Experimental Design: We examined whether intratumoral administration of DCs infected with recombinant adenovirus expressing murine wild-type p53 (Ad-mp53) could induce systemic antitumor responses against mutant p53-expressing tumors, highly immunogenic MethA, or weakly immunogenic MCA-207 implanted in syngeneic mice. Results: Accumulation of wild-type p53 protein in bone marrow-derived murine DCs could he successfully achieved by Ad-mp53 infection. Treatment with intratumoral injection of Ad-mp53-transduced DCs caused a marked reduction in the in vivo growth of established MethA and MCA-207 tumors with massive cellular infiltrates. Administration of p53-expressing DCs suppressed the growth of both injected MCA-207 tumors and untreated distant MCA-207 tumors, but not unrelated Lewis lung carcinoma tumors, suggesting the augmentation of systemic immunogenicity against MCA-207 tumor cells. Moreover, intratumoral injection of p53-expressing DCs had a greater antitumor effect than did s.c. immunization. Conclusions: Our results indicate that intratumoral administration of DCs expressing murine wild-type p53 leads to significant systemic immune responses and potent antitumor effects in mutant p53-expressing murine cancer models. These findings raise the possibility of using this strategy of intratumoral injection of p53-expressing DCs for human cancer treatment.

PURPOSE: To determine the effectiveness of computed tomography (CT)-guided radiofrequency (RF) ablation of malignant thoracic tumors.
MATERIALS AND METHODS: CT-guided RF ablations of 99 malignant thoracic tumors (3-80 mm in largest diameter; mean, 19.5 mm) were performed in 35 patients in 54 sessions. Ablation was performed with an RF generator by using a single internally cooled electrode. Tumors were both primary (three lesions) and, secondary (pulmonary or pleural metastases, 96 lesions). Follow-up was 1-17 months (mean, 7.1 months). Follow-up CT and histopathologic examinations were evaluated. Univariate analysis was performed with the Fisher exact test and Welch, t test was used to evaluate differences between group means. P < .05 represented a significant difference. The maximal diameter of each residual tumor or local recurrence or the proportion of primary lesions of pulmonary metastatic tumors with recurrence after RF ablation were analyzed. Complications, management, and outcomes of the complications were recorded.
RESULTS: The appearance of each ablation zone, including the target tumor and surrounding normal lung parenchyma, showed involution at follow-up CT. Local recurrence was demonstrated histopathologically or radiologically in nine tumors. The other 90 tumors showed no growth progression at follow-up CT. Probable complete coagulation necrosis obtained with initial RF ablation was achieved in 91% (90 of 99) of the tumors. The mean maximal diameter of the nine tumors (19.6 mm +/- 7.7 [SD]) was not significantly different (P = .994) from that of the other 90 tumors (19.5 mm +/- 13.0). Primary lesions of those nine metastatic tumors varied and did not demonstrate a specific tendency. Complications included pneumothorax, fever higher than 37.5&DEG;C, hemoptysis, cough, pleural effusion, abscess formation, and hemothorax. The overall complication rate was 76% (41 of 54 sessions).
CONCLUSION: RF ablation seems to be a promising treatment for malignant (C) RSNA, 2004.

Adenovirus-mediated wild-type p53 gene transfer induces apoptosis in a variety of human cancer cells. Although clinical trials have demonstrated that a replication-deficient recombinant adenovirus expressing the wild-type p53 gene (Ad-p53) is effective in suppressing growth of non-small cell lung cancer (NSCLC), we often experienced late resistance to this treatment. To elucidate the mechanism of late resistance to Ad-p53 in human lung cancer cells, we generated 5 different resistant variants from p53-susceptible H1299 NSCLC cells by repeated infections with Ad-p53. We first examined the transduction efficiency of adenoviral vector by Ad-LacZ transduction followed by X-gal staining in parental and 5 resistant H1299 cell lines. Their sensitivity to viral infection decreased in correlation with the magnitude of resistance, and Ad-p53-mediated tumor suppression could be restored by dose escalation of Ad-p53 in the resistant variants. The expression of Coxsackie and adenovirus receptor (CAR) and αV integrins, which are cellular receptors for attachment and internalization of the virus, respectively, was next investigated in these cell lines. Flow cytometry revealed that αVβ3 and αVβ5 integrin expression was consistent, while p53-resistant cell lines showed that diminished CAR expression correlated with the magnitude of the resistance. Our results demonstrated that decreased CAR expression could be one of the mechanisms of late resistance to Ad-p53, which may have a significant impact on the outcome of adenovirus-based cancer gene therapy.

Background: Gene therapy is an innovative therapeutic approach for cancer. An adenoviral vector expressing the tumour suppressor p53 gene (Ad/p53) is currently under clinical evaluation for various cancers. We recently developed a binary adenoviral vector system that can express the strong proapoptotic gene Bax (Ad/ PGK-GV16+ Ad/ GT-Bax: Ad/Bax).
Aims: To evaluate the potential of Bax gene therapy for gastric cancer, we assessed its antitumour effect in comparison with that of p53.
Methods: The human gastric cancer cell lines MKN-1, MKN-7, MKN-28, and MKN-45 were treated with Ad/ Bax or Ad/ p53, and cell viability, transgene expression, and caspase activation were assessed in vitro. To compare the antitumour effects of Ad/ Bax and Ad/ p53 treatment in vivo, subcutaneous tumours and peritoneal dissemination of MKN-45 cells were generated in nude mice. Each mouse underwent intratumoral or intraperitoneal administration of viruses and the growth of implanted tumours was observed after treatment.
Results: Treatment with Ad/ Bax and Ad/ p53 resulted in marked Bax and p53 protein expression and effective apoptosis induction in MKN-1, MKN-7, and MKN-28 cells in vitro. In contrast, MKN-45 cells showed resistance to Ad/ p53 and only treatment with Ad/ Bax resulted in activation of caspase 3 expression and massive apoptosis. Ad/ Bax treatment was more effective in suppressing both subcutaneous and peritoneally disseminated MKN-45 tumours compared with Ad/ p53 treatment.
Conclusion: Ad/ Bax treatment significantly inhibited the growth of even p53 resistant gastric cancer in vitro and in vivo. Therefore, adenovirus mediated Bax gene transfer may be useful in gene therapy for gastric cancers.

The objective of this study was to assess the feasibility and effectiveness of an induction chemoradiotherapy regimen followed by surgery in patients with locally advanced non-small-cell lung cancer (LA-NSCLC). A total of 22 patients with LA-NSCLC were treated with induction chemoradiotherapy consisting of cisplatin (40 mg m(-2)) and docetaxel (40 mg m(-2)) given on days 1, 8, 29 and 36 plus concurrent thoracic irradiation at a dose of 40-60 Gy (2 Gy fraction(-1) day(-1)). Surgical resection was performed within 6 weeks after completion of induction therapy. Objective response to the induction therapy was obtained in 16 patients (73%). In all, 20 patients (91%) underwent surgery and complete resection was achieved in 19 patients (86%). Pathological downstaging and pathological complete response were obtained in 14 (64%) and five (23%) patients, respectively. With a median follow-up period of 32 months, the calculated 3-year overall and progression-free survival rates were 66 and 61%, respectively. It is noteworthy that the 3-year overall survival rate in 14 patients achieving pathological downstaging was extremely high (93%). Toxicity was manageable with standard approaches. No treatment-related deaths occurred. This combined modality treatment is feasible and highly effective in patients with LA-NSCLC. The results warrant further large-scale study to confirm the effectiveness of this regimen.

Purpose: Replication-selective tumor-specific viruses present a novel approach for treating neoplastic disease. These vectors are designed to induce virus-mediated lysis of tumor cells after selective viral propagation within the tumor. Telomerase activation is considered to be a critical step in carcinogenesis, and its activity is closely correlated with human telomerase reverse transcriptase (hTERT) expression. We investigated the antitumor effect of the hTERT-specific replication-competent adenovirus on human cancer cells. Experimental Design: We constructed an adenovirus 5 vector [tumor- or telomerase-specific replication-competent adenovirus (TRAD)], in which the hTERT promoter element drives expression of E1A and E1B genes linked with an internal ribosome entry site, and we examined the selective replication and antitumor effect in human cancer cells in vitro and in vivo. Results: TRAD induced selective E1A and E1B expression in human cancer cells, but not in normal cells such as human fibroblasts. TRAD replicated efficiently and induced marked cell killing in a panel of human cancer cell lines, whereas replication as well as cytotoxicity was highly attenuated in normal human fibroblasts lacking telomerase activity. In nu/nu mice carrying s.c. human lung tumor xenografts, intratumoral injection of TRAD resulted in a significant inhibition of tumor growth. No evidence of TRAD was identified in tissues outside of the tumors, despite the presence of TRAD in the circulation. Moreover, TRAD replication in the distant, noninjected tumors was demonstrated. Conclusions: Our results suggest that the hTERT promoter confers competence for selective replication of TRAD in human cancer cells, an outcome that has important implications for the treatment of human cancers.

記述言語：英語出版者・発行元：SPRINGER-VERLAG

Background: Gene transfer to the esophageal epithelium holds the potential for the therapy of malignant as well as premalignant lesions in the upper gastrointestinal tract. Replication-deficient recombinant adenoviruses represent an efficient means of introducing genes in vivo into cells in a variety of organs. The majority of in vivo studies utilize direct submucosal injection for delivery of the viral vectors into the locoregional area of the gut; transferring genes into epithelial cells, however, is difficult because viruses are retained in the subepithelial space. To establish the efficient method for gene transfer into the epithelial cells, we have developed a multiluminal spray catheter that can be passed through the accessory channel of an endoscope, and we have evaluated the feasibility of fibrin glues as a vehicle of recombinant adenoviruses in a porcine model.
Methods: The fibrinogen solution and the thrombion solution containing an E1/E3 deleted recombinant adenovirus expressing the bacterial lacZ gene (Ad-lacZ) were endoscopically sprayed on the porcine esophagus through the catheter attached to the dual-barrel syringe. Twenty-four hours after gene delivery, beta-galactosidase activity of the esophagus was determined under the microscope following X-gal staining.
Results: The fibrin glue could be locally sprayed on the porcine esophagus by using the multichannel catheter through the endoscope. Attachment of the fibrin glue comtining Ad-lacZ caused strong beta-galactosidase staining on epithelial cells in the mucosal surface, but not in the basal cell layer.
Conclusion: Endoscopic local delivery of recombinant adenoviruses in aerosolized fibrin glues through a multiluminal catheter could provide an optimal technique for gene transfer into epithelial cells in the mucosal surfece, which may have important implications for the treatment of human esophageal premalignant diseases.

Ectopic p21(sdi1) gene transfer induces retinoic acid receptor beta expression and sensitizes human cancer cells to retinoid treatment

F Teraishi, Y Kadowaki, Y Tango, T Kawashima, T Umeoka, S Kagawa, N Tanaka, T Fujiwara

INTERNATIONAL JOURNAL OF CANCER 103 ( 6 ) 833 - 839 2003年3月

記述言語：英語出版者・発行元：WILEY-LISS

The biological effects of retinoic acid (RA) are mediated by nuclear retinoic acid receptors (RARs) that function as ligand-activated transcriptional factors. The response of human cancer cells to RA is known to be associated with the expression of RARbeta. Recent studies have demonstrated that the loss of RARbeta expression is involved in the development of a variety of human malignancies. We show that recombinant adenovirus-mediated p21(sdi1) gene transfer enhances RARbeta mRNA expression as well as protein expression and induces the sensitivity to all-trans RA (ATRA) in human cancer cells. Semi-quantitative reverse transcription-polymerase chain reaction analysis demonstrated that infection with adenovirus carrying human p21(sdi1) gene (AdSCMV-p21), which encodes a cyclin-dependent kinase inhibitor, induced RARbeta mRNA and protein expression in H1299 human non-small cell lung cancer cells and DLD-1 human colorectal cancer cells. We also found that exogenous introduction of the p21(sdil) gene transcriptionally activated the upstream promoter function of the RARbeta gene. Treatment with I muM of ATRA showed no significant inhibitory effects on the growth of H 1299 and DLD-1 cells; after Ad5CMV-p21 infection, however, cells underwent apoptosis with ATRA treatment at the same concentration, suggesting that p21(sdil) gene transfer sensitized H1299 and DLD-1 cells, presumably, through RARbeta upregulation. We also demonstrated the efficacy of intratumoral injection of AdSCMV-p21 in combination with systemic administration of ATRA in a nude mice xenograft model. Our results indicate that recombinant adenovirus-mediated p21(sdil) gene transfer could be potentially useful for the local induction of RA sensitivity in human premalignant and malignant lesions lacking appropriate RARbeta expression.

The prognosis in case of non-small cell lung cancer (NSCLC) remains poor, and novel treatment modalities are urgently needed for advanced NSCLC. Backed by advances in the understanding of cancer biology, gene therapy has been developed in recent years. The p53 gene is altered in over 50% of cancers and has been extensively studied as a tumor suppressor gene. Adenoviral-mediated p53 gene transfer is currently under clinical evaluation worldwide for the treatment of cancer. We are now conducting a phase I study of Ad-p53 for advanced NSCLC patients in Japan. As an interim report, we provide a brief summary of the current status of this study, highlighting the safety and clinical efficacy of Ad-p53. As of September 2002, 13 patients were enrolled to this study, and safety and antitumor effects have been noted.

p14ARF, a product of theINK4A/ARF locus, induces p53 upregulation by neutralizing the effects of MDM2, a transcriptional target of p53 that antagonizes its function. Here we report that adenovirus-mediated p14ARF gene transfer leads to the accumulation of ectopically transduced p53 and to apoptosis in human cancer cells. We constructed an adenoviral vector expressing p14ARF (Ad-ARF) and examined its synergistic effect with p53-expressing adenovirus (Ad5CMV-p53 or Ad-p53) in human lung and esophageal cancer cells. Simultaneous Ad-ARF and Ad-p53 infection increased p53 protein levels not only in a wild-type p53-expressing cell line, but also in cell lines with deleted p53. This resulted in a significant in vitro cytotoxicity compared with Ad-p53 infection alone. Coinfection of Ad-ARF and Ad-p53 also resulted in an increase in expression of p53-inducible genes, including p21WAF-1/Cip1, p53R2, and Noxa. In addition, the growth of human lung cancer tumors subcutaneously implanted into nu/nu mice was inhibited significantly by intratumoral injection with Ad-ARF and Ad-p53. Our data demonstrate that overexpression of ectopic p14ARF may render cells more sensitive to p53-mediated apoptosis, an outcome that has important implications for the treatment of human cancers.

The p16 tumor suppressor gene is frequently inactivated in human cancer tissues and cell lines. We previously reported that wild-type p16 expression from an adenovirus vector (Adv/p16) induced p53-dependent apoptotic cell death in non-small cell lung cancer (NSCLC) cell fines. Here we show the potential mechanism of apoptosis induced by Adv/p16 infection. Infection of human NSCLC cell line A549, which carries the wild-type p53 gene, with Adv/p16 resulted in activation of caspase-3, accompanied by the cleavage of its substrate poly (ADP-ribose) polymerase (PARP), on day 3 of infection. The retinoblastoma (Rb) cell cycle regulator protein was also cleaved after activation of caspase-3; when the levels of Rb significantly diminished, apoptosis began. When A549 cells were pretreated with the caspase-inhibitory peptide N-acetyl-asp-Glu-Val-Asp-CHO (aldehyde) (Ac-DEVD-CHO), Adv/p16-mediated apoptosis and Rb cleavage were greatly inhibited. Furthermore, MDM2, a negative regulator of p53 expression was upregulated 3 days after Adv/p16 infection, and MDM2 was subsequently cleaved by caspase-3; MDM2 cleavage was inhibited by Ac-DEVD-CHO treatment. These data implied that cleavage of Rb, in addition to activation of caspase-3, represented a mechanism by which Adv/p16 induced apoptotic cell death in human NSCLC cells. Our results support the clinical relevance of Adv/p16 as a treatment for p16-null human NSCLC that express wild-type p53.

The tumor suppressor p53 gene product is an essential component of the cytotoxic pathway triggered by DNA-damaging stimuli such as chemotherapeutic agents and ionizing radiation. We previously demonstrated that adenovirus-mediated wild-type p53 gene transfer could enhance the cytotoxic actions of chemotherapeutic drugs both in vitro and in vivo; however, the molecular mechanism of this chemosensitization is still unclear. Cyclin D1 is a major regulator of the progression of cells into the proliferative stage of the cell cycle. Here we show that infection with an adenovirus vector expressing the wild-type p53 gene (Ad-p53) caused an increase in cyclin D1 protein levels in human colorectal cancer cell lines DLD-1 and SW620; treatment with the anti-cancer drug adriamycin, however, down-regulated their cyclin D1 protein expression in a dose-dependent manner. The suppression of cyclin D1 expression following adriamycin treatment could be blocked by simultaneous Ad-p53 infection. Furthermore, DLD-1 and SW620 cells transfected with the cyclin D1 expression construct displayed increased sensitivity to adriamycin compared to that of the vector-transfected control. Our results suggest that ectopic wild-type p53 gene transfer results in increased cyclin D1 expression and, consequently, sensitizes human colorectal cancer cells to chemotherapeutic agents.

We investigated the role of wild-type p53 and c-myc activity in apoptosis induced by a combination of natural human tumor necrosis factor alpha (TNF-alpha) and natural human interferon alpha (IFN-alpha). Studies were performed with two human non-small-cell lung cancer cell lines, H226b, which has wild-type p53, and H226br, which has a mutant p53. The combination of IFN-alpha and TNF-alpha significantly inhibited cell growth and induced apoptotic cell death of both H226b and H226br, compared with IFN-alpha or TNF-alpha alone. Treatment with one or both cytokines did not affect the expression level of p53 in both cell lines. These results suggest that the combination of IFN-alpha /TNF-alpha induces apoptotic cell death through a p53- independent pathway. The c-myc oncogene is known to be involved in apoptosis induced by TNF. Antisense c-myc oligonucleotides have been reported to modulate cell growth or apoptosis in several cell lines. Antisense oligodeoxynucleotides were added to the culture of H226br cells before the addition of IFN-alpha /TNF-alpha. Antisense c-myc inhibited IFN-alpha /TNF-alpha cytotoxicity and apoptotic cell death. In conclusion, this study provides support for the speculation that TNF-alpha /TFN-alpha induce apoptosis through a c-myc-dependent pathway rather than a p53-dependent pathway.

Apoptosis is a morphologically distinct form of programmed cell death that plays a major role in cancer treatments. This cellular suicide program is known to be regulated by many different signals from both intracellular and extracellular stimuli. Here we report that p53 suppressed expression of the cellular FLICE-inhibitory protein (FLIP) that potentially blocks apoptotic signaling in human colon cancer cell lines expressing mutated and wild-type p53. In contrast, the expression of the death receptor KILLER/DR5 (TRAIL-R2) had no effect on FLIP expression, although exogenous p53 is known to induce KILLER/DR5 expression. In line with these observations, FLIP-negative cancer cells were sensitive to both p53- and KILLER/DRS-mediated apoptosis, whereas cells containing high levels of FLIP underwent apoptotic cell death when triggered by ectopic p53 expression but not by KILLER/DR5 expression. Treating the cells with a specific inhibitor of the proteasome inhibited the decrease of FLIP by p53, suggesting that p53 enhances the degradation of FLIP via a ubiquitin-proteasome pathway. Thus, the data indicate that p53-mediated downregulation of FLIP may explain the potent sensitization of human cancer cells to the apoptotic suicide program induced by wild-type p53 gene transler.
