Increasing evidence revealed that ten-eleven translocation 1 (TET1) plays an important role in tumorigenesis and chemoresistance, but its functions in gemcitabine resistance in cholangiocarcinoma (CCA) remain unknown. This study aims to investigate the effect of TET1 on gemcitabine resistance in CCA and the possible effect on P-glycoprotein (P-gp) expression encoded by multidrug resistance (MDR) genes. We established two kinds of gemcitabine-resistant CCA cell lines and confirmed its specific features. Read More

Purpose: To compare the cross-sectional imaging findings of immunoglobulin G4-related sclerosing cholangiopathy (IgG4-SC) and cholangiocarcinoma (CCA).

Methods: Retrospective search of radiology and pathology databases identified 24 patients with IgG4-SC and over 500 patients with CCA from January 2009 to December 2016. Patients with no pre-treatment imaging studies available on PACS, non-contrasted imaging only, presence of mass lesions, metastatic disease or biliary stents were excluded. Read More

Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease characterized by progressive fibroinflammatory destruction of the intra- and/or extrahepatic biliary ducts. While its features and disease course can be variable, most patients with PSC have concurrent inflammatory bowel disease and will eventually develop liver cirrhosis and end-stage liver disease, with liver transplantation representing the only potentially curative option. Importantly, PSC is associated with a significantly increased risk of malignancy compared to the general population, mainly cholangiocarcinoma, gallbladder carcinoma, hepatocellular carcinoma, and colorectal cancer, with nearly 50% of deaths in patients with PSC being due to cancer.

The practice of hepatic surgery has become increasingly complex as additional therapeutic options emerge to treat both primary and metastatic tumors of the liver. Liver-directed therapy options include selective internal radiation therapy (SIRT), stereotactic body radiation therapy, chemoembolization, bland embolization, hepatic artery infusion chemotherapy (HAIC), and ablative techniques such as microwave or radiofrequency ablation. Hepatocellular carcinoma has been treated with many of these therapies for palliation of symptoms, definitive treatment, and as a bridge to transplantation. Read More

Among the acquired modifications in cancer cells, changes in lysosomal phenotype and functions are well described, making lysosomes a potential target for novel therapies. Some weak base lipophilic drugs have a particular affinity towards lysosomes, taking benefits from lysosomal trapping to exert anticancer activity. Here, we have developed a new lysosomotropic small molecule, GNS561, and assessed its activity in multiple in vitro intrahepatic cholangiocarcinoma models (HuCCT1 and RBE cell lines and patient-derived cells) and in a chicken chorioallantoic membrane xenograft model.

Background: Intrahepatic sarcomatoid chonalgiocarcinoma (s-CCC) is an extremely rare disease, accounting for less than 1% of hepatobiliary system malignancies, and its pathophysiology is not well known. On the hypothesis that its clinical, serologic, or radiologic diagnosis are not fully understood and its prognosis is poor, we investigated the distinguishing features of s-CCC compared with those of intrahepatic bile duct adenocarcinoma [cholangiocellular carcinoma (CCC)] in patients from a single center.

Aim: To analyze the clinical, serologic, imaging, and histopathologic characteristics of intrahepatic s-CCC patients diagnosed in a single center. Read More

Background: Cholangiocarcinoma (CCA) is the second most common subtype of primary hepatobiliary cancer and one of the most aggressive characterized by an extremely poor prognosis with limited treatment options. Inflammatory cells in tumor microenvironment support tumor growth in term of progression, angiogenesis and metastatic capacity. A link between inflammation and biliary carcinogenesis has been previously observed but the mechanisms involved remain to be determined. Read More

Hedgehog (HH) signaling participates in hepatobiliary repair after injury and is activated in patients with cholangiopathies. Cholangiopathies are associated with bile duct (BD) hyperplasia, including expansion of peribiliary glands, the niche for biliary progenitor cells. The inflammation-associated cytokine interleukin (IL)-33 is also up-regulated in cholangiopathies, including cholangiocarcinoma. Read More

Background: Cholangiocarcinoma (CCA) complicates primary sclerosing cholangitis (PSC) in 10-20% of cases, but current tools for prediction of a CCA diagnosis are inadequate. Recently we demonstrated the utility of the ELF test to stratify prognosis in PSC. We observed that patients with PSC+CCA had significantly higher ELF score than those with PSC alone. Read More

Cholangiocarcinoma (CCA) is a highly-aggressive malignancy arising from the biliary tree, characterized by a steady increase in incidence globally and a high mortality rate. Most CCAs are diagnosed in the advanced and metastatic phases of the disease, due to the paucity of signs and symptoms in the early stages. This fact, along with the poor results of the local and systemic therapies currently employed, is responsible for the poor outcome of CCA patients and strongly supports the need for novel therapeutic agents and strategies.

PD901, a MEK inhibitor, has been demonstrated of therapeutic efficacy against cholangiocarcinoma (CCA) harboring K-Ras oncogenic mutations. However, most CCA exhibit no K-Ras mutations. In the current study, we investigated the therapeutic potential of PD901, either alone or in combination with the pan-mTOR inhibitor MLN0128, for the treatment of K-Ras wild-type CCA in vitro using human CCA cell lines, and in vivo using AKT/YapS127A CCA mouse model.

To combat and eventually eliminate the transmission of the liver fluke Opisthorchis viverrini, an accurate and practical diagnostic test is required. A recently established urine antigen detection test using monoclonal antibody-based enzyme-linked-immunosorbent assay (mAb-ELISA) has shown promise due to its high diagnostic accuracy and the use of urine in place of fecal samples. To further test the utility of this urine assay, we performed a cross sectional study of 1,043 people in 3 opisthorchiasis endemic communities in northeast Thailand by applying urine antigen detection together with copro-antigen detection methods.

Hilar cholangiocarcinoma is a highly malignant tumor and is currently treated by surgical resection or liver transplantation; however, these treatments result in poor patient prognosis accompanied with high recurrence and low patient mortality rates. Neoadjuvant therapy with liver transplantation is a novel treatment that exhibits promising clinical application, with a reported 5-year survival rate of 82%. However, transplantation centers conducting research into this treatment are limited due to its length and complexity. Read More
