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.
