In our institute, we introduced PET-CT examination as the preoperative and postoperative screening for esophageal cancer patients in April 2006. During two years before the introduction of PET-CT examination, we performed an intensive local control therapy (operation, RFA, definitive chemoradiotherapy) to 13 cases with single region recurrence (including 5 cases of cervical lymph nodes recurrence, 5 of local recurrence, 3 of distant metastatic recurrence). On the other hand, we performed an intensive local control therapy to 21 cases (including 4 cases of cervical lymph nodes recurrence, 10 of local recurrence, and 7 of distant metastatic recurrence) during two years after the introduction of PET-CT examination. In any pattern, there was a tendency of improvement in the prognosis of recurrent esophageal cancer patients. These results raised the possibility that PET-CT examination was useful for an early detection of the recurrent lesions in postoperative follow-up for esophageal cancer patients. And there might be a chance of curability in patients with single region recurrence by the early detection.

Gastroenterological Endoscopy 51 ( 5 ) 1284 - 1289 2009.5

Language：Japanese Publisher：Japan Gastroenterological Endoscopy Society

Endoscopic submucosal dissection (ESD) is becoming a common and useful treatment for superficial esophageal cancer, especially for tumors confined to the lamina propria mucosae which can be completely resected without any cancers fraction left. Here we report a case in which an SM infiltrated esophageal cancer resected by ESD, revealed a rapid and aggressive metastasis to a mediastinal lymph node (n106recR) before additional curative surgery. The possible existence of the lymph node metastasis could not be denied by retrospective re-assessment of CT which was performed before ESD. Although a relationship between the aggressive lymph node metastasis and the ESD procedure is unclear in this case, careful preoperative evaluation is necessary for the expansion of the indication of ESD for esophageal cancers.

Language：Japanese Publishing type：Research paper (scientific journal)

We report a case of a woman in her sixties having primary duodenal carcinoma with multiple liver metastases who was treated with oxaliplatin in combination with infusional 5-fluorouracil/Leucovorin(FOLFOX regimen). After completing 2 courses of the chemotherapy, computed tomography showed a partial response without any severe adverse events. Now at 8 months, the PR stage has been maintained. So far, no standard therapeutic strategy for metastatic duodenal carcinoma has been developed. However, we suggest a FOLFOX regimen can be highly effective as a safe approach for continuously maintaining the quality of life of patients with this rare type of cancer.

Establishment of a lymph node metastasis model from subcutaneous tumors of gastrointestinal stromal tumor model cells. Reviewed International journal

Language：English Publishing type：Research paper (scientific journal)

There is currently no suitable animal model of metastasis using cultured human gastrointestinal stromal tumor cells even though the molecular mechanisms of c-KIT-mediated progression and metastasis should be clarified. Ba/F3 murine lymphocyte cells transduced with mutant c-KIT have been utilized to analyze some molecular mechanisms related to a constitutively activated c-KIT signaling and to assess the efficacy of molecular-targeted inhibitors. Using this cellular system, we coincidentally discovered the development of axillary and inguinal lymph node swelling three weeks after subcutaneous injection of Ba/F3 cells with c-KIT mutation into nude mice. Mutation-specific PCR detected c-KIT mutation in the swollen lymph nodes but not in unmetastasized normal lymph nodes, indicating that the lymph nodes contain tumor cells which should come from a primary subcutaneous tumor. Microscopic observation revealed tumor cells infiltrating through lymphatic follicles with Ki-67-positive staining to distinguish them from lymphocytes. The significance of this model is helpful to understand the molecular mechanisms of c-KIT-mediated metastasis and is useful for assessments of molecular therapeutics and in vivo imaging.

TAE226, a dual inhibitor for FAK and IGF-IR, has inhibitory effects on mTOR signaling in esophageal cancer cells. Reviewed International journal

Language：English Publishing type：Research paper (scientific journal)

Esophageal cancer is one of the most aggressive cancers in the world. Novel preventive and therapeutic strategies tend to target the key molecules involved in the signaling transduction pathways for cell growth. It is known that FAK and mTOR are important controllers of cell growth. TAE226, a novel small molecule compound, is a potent ATP competitive inhibitor of FAK and IGF-IR. TAE226 can block FAK and IGF-IR signaling pathways. The purpose of this study was to explore the inhibitory effects on mTOR signaling and the mechanism of cell growth suppression by TAE226. We examined the expression of mTOR and S6 in esophageal cancer cells (SEG-1) and normal esophageal epithelial cells (KOB-13) and the efficacy of TAE226 against SEG-1 cells. mTOR and S6 were overexpressed in SEG-1 cells compared with KOB-13 cells. TAE226 inhibited the expression of mTOR, Akt, p70S6K and S6 as well as the phosphorylation of mTOR (Ser2448), Akt (Ser473), p70S6K (Thr389) and S6 (Ser240/244). As a result, TAE226 induced a dose-dependent decrease in cell growth (number) and damage in the cell shape. Together, these data show that TAE226 has potent inhibitory effects on mTOR signaling and esophageal cancer cell growth indicating that TAE226 has potential application in esophageal cancer treatment.

Language：Japanese Publishing type：Research paper (scientific journal)

We examined clinicopathological characteristics and prognoses of seventy advanced colorectal cancer cases by measuring pyrimidine nucleoside phosphorylase (PyNPase) and dihydropyrimidine dehydrogenase (DPD) in tumor and normal tissue. PyNPase activities in cancerous tissue obtained from resected were 82.7 +/- 41.9 U/mg protein, which were significantly higher than 37.2 +/- 24.0 U/mg protein in normal tissue (p < 0.001). On the other hand, DPD activities in cancerous tissue were significantly lower in normal tissue (p < 0.05). In cases with lymphnode metastases, PyNPase activities of cancerous tissue were significantly higher than that of no lymphnode metastases cases (p < 0.05). In cases with grade 2 side-effects or higher by oral adjuvant chemotherapy, DPD activities in normal tissue were significantly lower than that of other cases (p < 0.05). With regard to Dukes' B and C cases that were resected curatively, PyNPase activities of cancerous tissue of higher group's prognosis were worse than that of the lower group. In the group received 5'-DFUR as adjuvant chemotherapy, non-recurrent survival rate of the group exhibiting higher PyNPase activities was better than that of the lower group.

The Japanese journal of thoracic and cardiovascular surgery : official publication of the Japanese Association for Thoracic Surgery = Nihon Kyobu Geka Gakkai zasshi 53 ( 7 ) 365 - 8 2005.7

Language：English Publishing type：Research paper (scientific journal)

A 67-year-old man was admitted to our hospital due to esophageal cancer. Cancer existed at the lower esophagus and subtotal esophagectomy and lymphadenectomy was performed. The postoperative course was uneventful. Pathological findings revealed moderately differentiated squamous cell carcinoma that metastasized to the abdominal lymph nodes which include the paraaortic lymph nodes. He complained of anorexia three months after the operation and was found to have multiple liver and mediastinal lymph node metastases. He was admitted for chemotherapy. Before starting chemotherapy, he suddenly died without any sign of hemorrhage or respiratory disorder. Autopsy showed metastatic lesions to the heart and mediastinal lymph nodes, liver, thoracic vertebrae, kidney, adrenal gland and heart. Metastatic nodules in the heart were on the ventricular septum where the conducting system exists. No direct invasion from the pericardium was observed. Blockade of the conducting system of the heart was considered to have caused the severe arrhythmia and sudden cardiac arrest.
