BACKGROUND: Distinguishing perihilar cholangiocarcinoma (PHC) from benign forms of sclerosing cholangitis affecting the hilar bile ducts is challenging, since histological confirmation of PHC is difficult to obtain and accurate non-invasive diagnostic tests are not available. IgG4-associated cholangitis (IAC), an imitator of PHC, may present with clinical and radiographical signs of PHC. IAC can be accurately diagnosed with a novel qPCR test. The aim of this study was to investigate the incidence and long-term activity of IAC in patients resected for PHC in a single tertiary center over a period of 30 years...

BACKGROUND: At present, intrahepatic cholangiocarcinoma is a contraindication for liver transplantation. However, previous studies in this field did not preselect patients on the basis of chemosensitivity or disease trajectory after neoadjuvant therapy. Experience with hilar cholangiocarcinoma has indicated that neoadjuvant therapy followed by liver transplantation in patients without disease progression results in a long-term survival benefit. We aimed to establish the potential efficacy of liver transplantation in patients with biologically responsive intrahepatic cholangiocarcinoma who have had sustained tumour stability or regression with neoadjuvant therapy...

Cholangiocarcinoma (CCA) is one of the most common hepatic and biliary malignancies, accounting for about 3% of all gastrointestinal tumors. GATA5 is a transcription factor capable of suppressing the development of various human cancer types. Transcriptional inactivation and CpG island (CGI) methylation of GATA3 and GATA5, two members of the GATA family of transcription factors, have been observed in some human cancers. But whether high-density CGI methylation of GATA5 is associated with the clinical course of CCA patients has not been clarified...

Liver cancer comprises a group of malignant tumors, among which hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) are the most common. ICC is especially pernicious and associated with poor clinical outcome. Studies have shown that a subset of human ICCs may originate from mature hepatocytes. However, the mechanisms driving the trans-differentiation of hepatocytes into malignant cholangiocytes remain poorly defined. We adopted lineage tracing techniques and an established murine hepatocyte-derived ICC model by hydrodynamic injection of activated forms of AKT (myr-AKT) and Yap (YapS127A) proto-oncogenes...

A characteristic shared by most frequent types of primary liver cancer, i.e., hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) in adults, and in a lesser extent hepatoblastoma (HB) mainly in children, is their high refractoriness to chemotherapy. This is the result of synergic interactions among complex and diverse mechanisms of chemoresistance (MOC) in which more than 100 genes are involved. Pharmacological treatment, although it can be initially effective, frequently stimulates the expression of MOC genes, which results in the relapse of the tumor, usually with a more aggressive and less chemosensitive phenotype...

Radiotherapy has been accounted as the most comprehensive cancer treatment modality over the past few decades. However, failure of this treatment modality occurs in several malignancies due to the resistance of cancer cells to radiation. It was previously reported by the present authors that defective cell cycle checkpoints could be used as biomarkers for predicting the responsiveness to radiation in individual patients with cholangiocarcinoma (CCA). However, identification of functional defective cell cycle checkpoints from cells from a patient's tissues is cumbersome and not applicable in the clinic...

A 72-year-old woman was examined by F-FDG PET/CT, showing pathologic tracer uptake in the gallbladder. PET/CT also depicted condition of situs inversus totalis, with dextrocardia, liver on the left side and spleen on the right side of the body. These findings were essential to plan and develop laparoscopic cholecystectomy, which diagnosed cholangiocarcinoma. The recognition of anatomical variants and abnormalities by means of hybrid PET/CT imaging is essential in order to plan the best therapeutic approach.

Intrahepatic cholangiocarcinoma (ICC) is a fatal, malignant tumor of the liver; effective diagnostic biomarkers and therapeutic targets for ICC have not been identified yet. High expression of H2A histone family member Z (H2A.Z) is a high-risk factor for poor prognosis in patients with breast cancer and primary hepatocellular cancer. However, the significance of H2A.Z and its expression in ICC remains unknown. The present study demonstrated that H2A.Z is overexpressed in ICC and expression of H2A.Z correlated with poor prognosis in patients with ICC...

Cholangiocarcinoma (CCA) is a lethal cancer associated with chronic inflammation that has increased in prevalence in recent decades. The dysregulated expression of microRNAs (miRNAs) has been detected in various types of malignancies, and depending on the target genes this can result in miRNAs functioning as tumor suppressors or oncogenes. In this study, we investigated the role of miR-124 in cholangiocarcinoma (CCA) and found that its expression was significantly downregulated in the tumor tissue of patients and in CCA cell lines...
