Laparoscopic resection of hilar cholangiocarcinoma is technically challenging because it involves complicated laparoscopic procedures that include laparoscopic hepatoduodenal lymphadenectomy, hemihepatectomy with caudate lobectomy, and hepaticojejunostomy. There are currently very few reports describing this type of surgery. Between August 2014 and December 2014, 5 patients underwent total lapa...

Hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) are the major adult liver cancers. The existence of combined hepatocellular-cholangiocarcinoma (CHC), a histopathologic intermediate form between HCC and CC, suggests phenotypic overlap between these tumors. Here, we applied an integrative oncogenomic approach to address the clinical and functional implications of the overlapping phenot...

Prdx1 is an important member of peroxiredoxins (Prdxs) regulating various cellular signaling and differentiation. Prdx1 confers an aggressive survival phenotype of cancer cells and drug-resistance, yet its role in hilar cholangiocarcinoma is not fully investigated. In present study, we detected the expression profile of Prdx1 in 88 hilar cholangiocarcinoma by tissue arrays and immunohistochemis...

Cholangiocarcinoma is an aggressive malignant tumor originating from intrahepatic or extrahepatic bile ducts. Its malignant phenotypes may be assumed by cancer stem cells (CSC). Here, we demonstrate that CD274 (PD-L1), known as an immunomodulatory ligand, has suppressive effects on CSC-related phenotypes of cholangiocarcinoma. Using two human cholangiocarcinoma cell lines, RBE and HuCCT1, we at...

BACKGROUND We examined the efficacy and toxicity of proton beam therapy (PBT) for treating advanced cholangiocarcinoma. METHODS The clinical data and outcomes of 28 cholangiocarcinoma patients treated with PBT between January 2009 and August 2011 were retrospectively examined. The Kaplan-Meier method was used to estimate overall survival (OS), progression-free survival (PFS), and local contro...

Cholangiocarcinoma is a high-mortality primary hepatic malignancy. A higher incidence of cholangiocarcinoma was reported in Asia, especially Southeast Asia, than in Western countries. Hilar cholangiocarcinoma is a specific type of extrahepatic cholangiocarcinoma that involves the hepatic hilum and has a worse prognosis. More than half of the patients with jaundice are inoperable at the time of ...

Cholangiocarcinoma is a highly malignant neoplasm of the biliary tree. It has a high rate of mortality, and currently, there is no effective chemoprevention and treatment. This study was designed to investigate the potential effect of omega 3 polyunsaturated fatty acids (omega 3-PUFA) on human cholangiocarcinoma cell growth and to determine their mechanisms of actions. Treatment of three human ...

Intrahepatic cholangiocarcinoma account for 13% of annual cancer-related deaths worldwide and for 3% in the USA. Patient with unresectable disease can benefit from palliative therapies such as systemic chemotherapy. However, the only curative treatment for intrahepatic cholangiocarcinoma is complete surgical resection with histologically negative resection margins.

Mucin is a high molecular weight glycoprotein that plays an important role to protect the gastrointestinal tract epithelium. However, in cancer cells and during cancer progression, the expression profile of mucins is altered and expression of some mucins is correlated with prognosis for certain malignancies. The aim of this study was to determine the relationship between the expression of MUC1,...

BACKGROUND The need for new therapies for cholangiocarcinoma is highlighted by their poor prognosis and refractoriness to chemotherapy. Increased production of Interleukin-6 promotes cholangiocarcinoma growth and contributes to chemoresistance by activating cell survival mechanisms. We sought to identify biologically active compounds capable of ameliorating the phenotypic effects of IL-6 expres...
