Background: The incidence of extrahepatic cholangiocarcinoma increases in recent years. But the diagnosis and treatment are still troublesome to surgeons. This study was designed to explore the value of surgical approach in the treatment of extrahepatic cholangiocarcinoma.
Methods: We retrospectively analyzed the clinical data of 135 patients with extrahepatic cholangiocarcinoma who had been treated in our hospital from January 1992 to December 2006.
Results: The ratio of extrahepatic cholangiocarcinoma to biliary duct diseases was 1.81%. The rates of total resection and radical resection were 70.75% (75/106) and 56.60% (60/106), respectively. The overall 1-, 3-, 5-year survival rates were 46.93%, 37.33% and 18.75%, respectively. The 1-, 3-, 5-year survival rates were better in the radical resection group (74.94%, 55.74% and 41.27%, respectively) than in the palliative resection group (42.86%, 26.79% and 26.79%, respectively) (P<0.05). The survival rates of patients who had undergone palliative resection were higher than those of patients who had been subjected to palliative drainage or non-operation: 1-, 3-, 5-year survival rates were 42.86%, 26.79%, 26.79% vs. 23.33%, 6.67%, 0 or 17.86%, 0, 0 (P<0.05). While the survival rates were not significantly different between palliative drainage and non-operation (P<0.05). Multivariate analysis revealed that the histopathological grades, TNM stages and modalities were key factors influencing the outcome.
Conclusions: The outcome of the patients with extrahepatic cholangiocarcinoma is still not optimistic. Radical resection is the first choice for the treatment of tumors.

Common pancreatobiliary epithelial malignancies such as pancreatic ductal adenocarcinoma, cholangiocarcinoma and gallbladder carcinoma have poor prognosis. A small but significant portion of these malignancies arise from mass-forming grossly and radiologically visible premalignant epithelial neoplasms in the pancreatobiliary tree. Several lesions, including a few recently described entities, fall under this category and predominantly include papillary epithelial lesions with or without mucin production.

Background And Aims: Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterised by progressive biliary inflammation and fibrosis, leading to liver cirrhosis and cholangiocarcinoma. GPBAR1 (TGR5) is a G protein-coupled receptor for secondary bile acids. In this study, we have examined the therapeutic potential of BAR501, a selective GPBAR1 agonist in a PSC model.

Background: Biliary tract cancers (BTCs) represent distinct biological and genomic entities. Anatomic and geographic heterogeneity in genomic profiling of BTC subtypes, genomic co-alterations, and their impact on long-term outcomes are not well defined.
Methods: Genomic data to characterize alterations among patients with BTCs were derived from the AACR GENIE registry (v15.

Department of Radiology, Xuzhou Central Hospital, Xuzhou, China.
Introduction: In an effort to treat patients with malignant hilar obstruction (MHO), both percutaneous trans-hepatic biliary stenting (PTBS) and endoscopic biliary stenting (EBS) strategies have been implemented in the clinic, but the relative advantages of these techniques remain to be clarified.
Aim: This meta-analysis was designed to compare the relative clinical efficacy of PTBS and EBS in MHO patients.Material and methods: Relevant studies were identified through searches of the PubMed, Web of science, and Wanfang databases, and pooled analyses of these studies were then performed.

Background: The purpose of the present study was to evaluate clinicopathological characteristics, patterns of recurrence, survival outcomes, and implications for the addition of chemoradiotherapy for patients with resected perihilar and intrahepatic cholangiocarcinoma (CCA).
Materials And Methods: For the present retrospective study, we identified 38 and 10 patients with resected perihilar and intrahepatic CCA. In perihilar CCA, adjuvant treatment was given as chemotherapy ( = 13) or chemoradiotherapy ( = 10).
