BACKGROUND A British randomised study of gemcitabine plus cisplatin (GC) combination showed promising results in biliary tract cancer (BTC) patients. In our study, we evaluated the efficacy and safety of this combination compared with gemcitabine alone (G) in Japanese BTC patients. METHODS Overall, 84 advanced BTC patients were randomised to either(More)
BACKGROUND We evaluated the efficacy and toxicity of adding oral leucovorin (LV) to S-1 when compared with S-1 monotherapy in patients with gemcitabine-refractory pancreatic cancer (PC). PATIENTS AND METHODS Gemcitabine-refractory PC patients were randomly assigned in a 1:1 ratio to receive S-1 at 40, 50, or 60 mg according to body surface area plus LV 25(More)
BACKGROUND Two recent studies (ABC-02 [UK] and BT22 [Japan]) have demonstrated the superiority of cisplatin and gemcitabine (CisGem) chemotherapy over gemcitabine (Gem) alone for patients with pathologically proven advanced biliary tract cancer (BTC: cholangiocarcinoma, gallbladder and ampullary cancers). This pre-planned analysis evaluates the efficacy of(More)
BACKGROUND Although several reports have described a possible association between DNA repair genes and pancreatic cancer (PC) in smokers, this association has not been fully evaluated in an Asian population. We assessed the impact of genetic polymorphisms in the base excision repair (BER) pathway on PC risk among Japanese. METHODS This case-control study(More)
We describe a 42-year-old man with von Hippel-Lindau disease and islet cell tumor of the pancreas. He had retinal and cerebellar hemangioblastomas. His sister had pheochromocytoma. A pancreatic tumor was detected by ultrasonography at his periodical medical checkup. Contrast enhanced computed tomography and abdominal angiography revealed a hypervascular(More)
OBJECTIVE This study aimed to elucidate the natural history of intraductal papillary mucinous neoplasm (IPMN) of the pancreas with mural nodules (MNs) in branch duct IPMN (BD-IPMN). METHODS Among the 402 registered patients with BD-IPMN on long-term follow-up at 10 institutions in Japan, 53 patients with MNs of less than 10 mm in height detected by(More)
The aquaporin (AQP) family of water channels is distributed ubiquitously in many epithelia and plays a fundamental role in transmembrane water transport. The aim of this study is to identify the water transport pathway in pancreatic duct cells where most of the HCO-rich fluid originates. Using digital videomicroscopy, we measured the osmotic water(More)
BACKGROUND The aim of this study was to determine a predictive indicator of gemcitabine (GEM) efficacy in unresectable pancreatic cancer using tissue obtained by endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA). METHODS mRNAs extracted from 35 pancreatic tubular adenocarcinoma tissues obtained by EUS-FNA before GEM-treatment were(More)
T he cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP regulated Cl 2 channel that is expressed in many epithelial tissues. 1 In the pancreas CFTR plays a key role in the apical HCO 3 – transport in duct cells. 2–5 Loss of its function due to mutations in the CFTR gene causes cystic fibrosis (CF) of the pancreas with exocrine(More)
Gemcitabine is a key drug for the treatment of pancreatic cancer; however, with its limitation in clinical benefits, the development of another potent therapeutic is necessary. Vascular endothelial growth factor receptor 2 is an essential target for tumor angiogenesis, and we have conducted a phase I clinical trial using gemcitabine and vascular endothelial(More)
