A randomized controlled trial has begun in Japan to compare orally administered S-1 with intravenous gemcitabine (GEM) as adjuvant chemotherapy for patients with curatively resected pancreatic cancer. Patients are enrolled within 10 weeks after pancreatectomy to be treated for six months after assignment to either S-1 (80 mg/m(2)/day for four weeks,(More)
OBJECTIVES The clinical significance of preoperative serum levels of tumor markers CEA and CA19-9 was evaluated in gastric cancer patients. METHODS Serum levels of CEA and CA19-9 were measured in 663 patients with gastric cancer who underwent laparotomies over a recent 4-yr period (1990-1993). The correlations between the serum levels of tumor markers and(More)
Several papers have shown that preoperative inflammation-based prognostic scores and/or immunonutritional status are associated with survival in patients with hepatocellular carcinoma (HCC). However, the validity of prognostic factors of these scores remains controversial. This study aimed to validate the power of prognostic scores based on the preoperative(More)
OBJECTIVE The authors defined a new macroscopic classification of liver metastases from colorectal cancer. SUMMARY BACKGROUND DATA There were different prognostic results after the same operative procedure for liver metastases with similar background factors. METHODS Eighty-one resected liver metastases were classified into simple nodular (SN) or(More)
Abstract Background. Farrar's criteria for cystic duct carcinoma (histopathological diagnosis of a carcinoma strictly limited to the cystic duct) have practical limitations. We propose new "working definition": a gallbladder tumor, the center of which is located in the cystic duct. Patients and methods. Between 1980 and 2000 we diagnosed cystic duct(More)
The aim of this study was to evaluate the value of positron emission tomography with 18F-labeled fluorodeoxyglucose (FDG-PET) as a preoperative diagnostic investigation in patients with biliary carcinoma. Seventy-two patients with potentially resectable biliary carcinoma underwent preoperative multidetector-row computed tomography (MDCT) and FDG-PET. Both(More)
OBJECTIVE To better determine the role of portal vein resection and its effect on survival, as well as to appreciate the impact of portal vein invasion on prognosis in hilar cholangiocarcinoma. SUMMARY BACKGROUND DATA Hepatectomy with portal vein resection is sometimes performed for locally advanced hilar cholangiocarcinoma. However, the significance of(More)
We retrospectively reviewed postoperative complications in 105 patients with hilar cholangiocarcinoma who underwent hepatectomy at Nagoya University Hospital from January 1990 through March 1999. Of the 105 subjects, 97 (92.4%) underwent resection of two or more Healey's segments of the liver. Combined portal vein resection was performed in 33 (31.4%)(More)
PURPOSE The carcinoembryonic antigen glypican-3 (GPC3) is an ideal target of anticancer immunotherapy against hepatocellular carcinoma (HCC). In this nonrandomized, open-label, phase I clinical trial, we analyzed the safety and efficacy of GPC3 peptide vaccination in patients with advanced HCC. EXPERIMENTAL DESIGN Thirty-three patients with advanced HCC(More)
The pancreatic fistula rate following distal pancreatectomy ranges widely, from 13.3 to 64.0 %. The optimal closure method of the pancreatic remnant remains controversial, especially regarding whether to use a stapler. All patients who underwent distal pancreatectomy in five Japanese hospitals from January 2001 to June 2009 were included in this study. All(More)
