Hepatectomy needing simultaneous reconstruction of the hepatic artery and the portal vein in the operation for cholangiocarcinoma is a challenging procedure. We experienced three cases of left hepatectomy with simultaneous reconstructions of the right hepatic artery (RHA) and the right portal vein (RPV) in all of which the surgical procedures were performed in the same manner. At the initial step of the procedure, we confirmed that the RHA and the RPV at the porta hepatis as well as the proper hepatic artery and the main portal vein (MPV) proximal to the cancer involvement could be controlled by tapes, which meant the cancer could be resected by means of vascular reconstructions...

Patients with advanced intrahepatic cholangiocarcinoma (ICC) have a poor prognosis and the therapeutic options available for treating ICC are limited. Sorafenib, a multikinase inhibitor of vascular endothelial growth factor receptor 2 and 3, platelet derived growth factor receptor-β, B-Raf proto-oncogene, serine/threonine kinase and C-Raf proto-oncogene, serine/threonine kinase, is a novel reference standard for the treatment of advanced hepatocellular carcinoma. Sorafenib has previously been demonstrated to exhibit significant antitumor activity in various cholangiocarcinoma cell lines and in xenograft ICC models...

Perihilar cholangiocarcinoma (pCC, also known as a Klatskin tumor) is the most common type of cholangiocarcinoma (CC). Preoperative biliary drainage (PBD) is indicated for pCC patients with acute cholangitis or patients who need portal vein embolization (PVE). However, the routine performance of PBD in other patients with pCC is still controversial. The current study retrospectively examined patients with pCC who did not undergo PVE and who did not have cholangitis who were seen at this Hospital to assess the advantages and disadvantages of PBD...

Cholangiocarcinoma (CCA) is a deadly disease that poorly responds to chemotherapy and radiotherapy and whose incidence has increased worldwide. Furthermore, long noncoding RNAs (lncRNAs) play important roles in multiple biological processes, including tumorigenesis. Specifically, H19, the first discovered lncRNA, has been reported to be overexpressed in diverse human carcinomas, but the overall biological role and clinical significance of H19 in CCA remains unknown. In the present study, expression levels of H19 were investigated in CCA tissues and cell lines and were correlated with clinicopathological features...

Patients with chronic liver disease (CLD) and cirrhosis are at high risk for hepatocellular carcinoma (HCC). Current diagnostic tools for HCC detection include imaging techniques and serum biomarkers such as α-fetoprotein (AFP). Yet, these methods are limited in sensitivity and specificity to accurately detect early HCC. Here we focused on the potential of soluble Axl (sAxl) as a biomarker in CLD patients by analyzing serum samples of 1067 patients and healthy controls from centers in Europe and Asia. We show that serum concentrations of sAxl were significantly increased at early (82...

The tumor suppressor FBXW7 has been demonstrated to degrade several oncoproteins, including c-Myc. Although low FBXW7 expression levels are suggested to be a poor prognostic factor in a number of types of solid tumor, the role of FBXW7 in chemosensitivity is controversial. The purpose of the present study was to determine whether FBXW7 expression may be used as a marker for poor prognosis and chemosensitivity in patients with cholangiocarcinoma (CC). FBXW7 expression was investigated by immunohistochemistry in 100 surgically resected CC samples, and the association between FBXW7 expression, clinicopathological factors and prognosis was evaluated...

It has been suggested that dichloromethane (DCM) and 1,2-dichloropropane (DCP) are responsible for occupational cholangiocarcinoma. Dihaloalkanes are metabolically activated by GSH S-transferase theta1 (GSTT1) to yield products such as episulfonium ions. However, whether the GSTT1-mediated step of these dihaloalkanes is related to occupational cholangiocarcinoma is not known. In the present study, we investigated the influence of GSTT1 activation on the mutagenicity of DCM and 1,2-DCP using GSTT1-expressing Salmonella typhimurium TA100 (TA100-GST)...

BACKGROUND: Cholangiocarcinoma (CCA) is highly resistant to chemo-therapy, including 5-fluorouracil (5-FU) treatment. MicroRNAs are endogenous and short non-coding RNAs that can regulate multiple genes expression. Many microRNAs have shown functional roles in the chemo-resistance of tumors. Here, we examined the relationship between microRNAs expression and the sensitivity of CCA cells to 5-FU. METHODS: Microarray analysis was used to determine the aberrantly expressed microRNAs in two 5-FU resistant CCA cell lines, KKU-M139 and KKU-M214 cells...

PURPOSE: Only a few studies have evaluated the clinicopathological significance of the p53 protein expression and s-p53-Abs level in patients with cholangiocarcinoma. We therefore analyzed the clinicopathological and prognostic significance of s-p53-Abs in patients with extrahepatic cholangiocarcinoma. METHODS: We prospectively evaluated s-p53-Abs levels before and after surgery in 61 patients with extrahepatic cholangiocarcinoma to determine the relationship between clinicopathological factors and the prognostic significance of s-p53-Abs...

Intrahepatic cholangiocarcinoma often causes death due to obstruction of the biliary system or interruption of the vascular supply of the liver. This fact emphasizes the critical need for local tumor control in this disease. Successful local tumor control has traditionally been achievable through surgical resection for the small proportion of patients with operable tumors. Technological advances in radiation oncology and in interventional radiology have enabled the delivery of ablative radiation doses or other cytotoxic therapies for tumors in the liver...

Intrahepatic cholangiocarcinoma (ICC) is a rare entity with a distinct clinical course and epidemiology from hilar and extrahepatic cholangiocarcinoma. ICC makes up 8-10% of cholangiocarcinomas and 10-20% of all primary liver tumors. There remains a considerable amount of geographic variation in the incidence of ICC worldwide; however, the overall incidence of this malignancy appears to be rising. Several risk factors have been identified, such as infectious causes (liver flukes, viral hepatitis), biliary tract disease [primary sclerosing cholangitis (PSC), hepaticolithiasis, biliary cystic diseases], metabolic syndrome, lifestyle choices (alcohol abuse, tobacco use), and cirrhosis...

Biliary tract cancer (BTC) is a heterogeneous group of cancers, which is composed of intrahepatic cholangiocarcinoma (ICCA), extrahepatic cholangiocarcinoma (ECCA), gallbladder cancers and ampullary carcinomas. While all anatomic subgroups are treated uniformly, our understanding about the pathogenesis has allowed us to reason that each group represents a clinically and genetically diverse disease. The majority of patients present with locally advanced or metastatic disease, where the standard treatment is combination systemic cytotoxic chemotherapy with gemcitabine and cisplatin...

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver cancer, accounting for 10-15% of primary hepatic malignancy. The incidence and cancer-related mortality of ICC continue to increase worldwide. At present, hepatectomy is still the most effective treatment for ICC patients to achieve long-term survival, although its overall efficacy may not be as good as that for patients with hepatocellular carcinoma (HCC) due to the unique pathogenesis and clinical-pathological profiles of ICC. Viral infection, lithiasis and metabolic factors may all be associated with the pathogenesis of ICC...

Intrahepatic cholangiocarcinomas account for approximately 20% of cases of cholangiocarcinomas. Three growth patterns or morphologic subtypes exist, including mass-forming, periductal-infiltrating, and intraductal-growth subtypes. Knowledge of these morphologic subtypes and their radiologic appearance aids in timely diagnosis, a key to optimizing patient outcomes. The morphologic variability of intrahepatic cholangiocarcinomas has a direct impact on the diagnostic sensitivity and specificity of various diagnostic imaging modalities, including ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP), and positron emission tomography (PET)...

Liver cancer, primarily encompassing hepatocellular carcinoma and intrahepatic cholangiocarcinoma, has become the second cause of worldwide cancer-related death during the past two decades. Lymphoepithelioma-like carcinomas (LELCs) are defined as tumors composed of undifferentiated epithelial cells with a prominent lymphoid infiltrate, and can arise in the liver as hepatocellular or cholangiocarcinoma forms. Patients with liver LELC display distinctive demographics and tumor characteristics. LELCs also appear to be associated with strikingly better outcomes compared to typical liver cancers, with 5-year survival rates of 57% to 100% versus 12% to 68%, respectively...

Cholangiocarcinoma (CCC) is an aggressive malignancy with poor therapeutic options and pronounced chemotherapy resistance. The bioactive broccoli substance, sulforaphane (SFN), is a promising new therapeutic option since it has been found to induce therapeutic effects in both experimental and epidemiological studies in various tumor entities. Thus, the present study was designed to assess the effect of SFN on cisplatin sensitivity in CCC. Human HuCCT-1 and TFK-1 cells, representing intrahepatic and extrahepatic CCC, respectively, were treated with cisplatin and SFN...
