The incidence rate of intrahepatic cholangiocarcinoma is rising, and treatment options are limited. Therefore, new biological markers of intrahepatic cholangiocarcinoma are needed. Immunohistochemistry and enzyme-linked immunosorbent assay were applied to analyze the expressions of CD97, CD55, and soluble CD97 in 71 patients with intrahepatic cholangiocarcinoma and 10 patients with hepatolithiasis. CD97 and CD55 were not expressed in hepatolithiatic tissues, but positive expression was observed in 76.1% (54/71) and 70...

Intrahepatic cholangiocarcinoma is increasing in frequency worldwide, but radical surgical treatment is practicable in 30-40% of cases. The median survival without therapy is about 8 months, increased to 12 months in combination with systemic chemotherapy. Therefore, locoregional therapies, such as, radiofrequency ablation or transarterial chemoembolization have been employed. Radioembolization with yttrium-90 microspheres ((90)Y-TARE) is a novel intrarterial treatment which could be included in the armamentarium of treatment options, having shown higher median survival (up to 22 months) and low complication rates...

Intrahepatic cholangiocarcinomas were classified into two types based on their microscopic appearance. Tumors with histologic similarities to hilar cholangiocarcinomas (predominantly ductal adenocarcinomas with minor tubular components, if present, restricted to the invasive front) were defined as the perihilar type, whereas the others were classified as peripheral cholangiocarcinomas. Among the 47 cases examined in the present study, 26 (55%) were classified as the perihilar type, whereas 21 (45%) were the peripheral type...

Intrahepatic cholangiocarcinoma (iCCA) is a malignancy with an increasing incidence and a high-case fatality. While surgery offers the best hope at long-term survival, only one-third of tumors are amenable to surgical resection at the time of the diagnosis. Unfortunately, conventional chemotherapy offers limited survival benefit in the management of unresectable or metastatic disease. Recent advances in understanding the molecular pathogenesis of iCCA and the use of next-generation sequencing techniques have provided a chance to identify "target-able" molecular aberrations...

To gain insight into the cellular and molecular interactions mediating the desmoplastic reaction and aggressive malignancy of mass-forming intrahepatic cholangiocarcinoma (ICC), we modeled ICC desmoplasia and progression in vitro. A unique three-dimensional (3D) organotypic culture model was established; within a dilute collagen-type I hydrogel, a novel clonal strain of rat cancer-associated myofibroblasts (TDFSM) was co-cultured with a pure rat cholangiocarcinoma cell strain (TDECC) derived from the same ICC type as TDFSM...

Cholangiocarcinoma (CCA) is an aggressive malignancy of the bile ducts, with poor prognosis and limited treatment options. Here, we describe the integrated analysis of somatic mutations, RNA expression, copy number, and DNA methylation by The Cancer Genome Atlas of a set of predominantly intrahepatic CCA cases and propose a molecular classification scheme. We identified an IDH mutant-enriched subtype with distinct molecular features including low expression of chromatin modifiers, elevated expression of mitochondrial genes, and increased mitochondrial DNA copy number...

Cholangiocarcinoma (CC) is the second most common type of primary liver cancer after hepatocellular carcinoma. Surgical resection is considered the only curative treatment for CC. In general, laparoscopic liver surgery (LLS) is associated with improved short-term outcomes without compromising the long-term oncological outcome. However, the role of LLS in the treatment of CC is not yet well established. In addition, CC may arise in any tract of the biliary tree, thus requiring different types of treatment, including pancreatectomies and extrahepatic bile duct resections...

BACKGROUND: Cholangiocarcinomas (CCAs) are aggressive malignancies that display features of biliary differentiation. According to their anatomical location, CCAs are commonly classified as intrahepatic and extrahepatic tumors, the latter entity being further subdivided into perihilar CCAs, also termed as Klatskin tumors, and distal tumors. While a majority of CCAs occur sporadically, established risk factors such as liver fluke infestation or primary sclerosing cholangitis exist. SUMMARY: Due to lack of efficient early screening markers, CCAs are frequently diagnosed at an advanced stage when curative surgical resection is not an option...

BACKGROUND AND OBJECTIVE: In 2010 we published that 53% of cases of hepatocellular carcinoma (HCC) detected in Spain were diagnosed outside the context of standard screening programs, which consequently leads to lower survival rates. The aim of this study was to analyze the current situation and the causes of diagnosis out of screening programs. MATERIAL AND METHODS: Prospective registry of 73 second- and third-level Spanish healthcare centers carried out between October 1, 2014 and January 31, 2015...

The presence of asbestos fibres (AFs) in drinking water could be linked with gastrointestinal cancers. However, it is not regulated in several countries due to conflicting evidence. Areas covered: Some reports mainly associated AF ingestion with gastric and colorectal cancer. Experimental evidence suggested a role for timing and extent of exposure, and showed that ingested AFs induce toxic effects on the stomach, ileum and colon, histological alterations and negative effects at a molecular level, cross the placenta and enter foetal organs (including the liver), and seem able to act as a co-carcinogen agent...

Intrahepatic cholangiocarcinoma (ICC) is a rare malignant tumor of the biliary tract with growing incidence and dismal prognosis. It is responsible for 10-20% of primary liver cancer worldwide, but early diagnosis is still a challenge and few treatment options are available. Aim of this review is to summarize the current knowledge about biological features and arising molecular patterns of this disease. The identification of emerging biomarkers and early detection of precursor lesions shall play a key role in the perspective of future tailored targeted therapies...

Cholangiocarcinoma is a relatively uncommon malignant neoplasm with poor prognosis. The distinction between extrahepatic and intrahepatic subtypes is important as epidemiological features, biologic and pathologic characteristics, and clinical course are different for both entities. This review study focuses on the role imaging plays in the diagnosis, classification, staging, and post-treatment assessment of cholangiocarcinoma.

FGFR2 genetic translocations are frequent in cholangiocarcinoma, yet despite initial sensitivity to FGFR inhibitors in clinic, patients quickly become resistant to targeted therapies. The work published by Goyal and colleagues demonstrates that acquisition of gatekeeper mutations in FGFR2 and intratumoral heterogeneity drive resistance in patients with FGFR2-translocated intrahepatic cholangiocarcinoma, which will have important implications for management of the disease in clinic.

Intrahepatic cholangiocarcinoma (ICC) comprises approximately 5-30% of primary liver tumors, however it has been increasing over the last several decades. Up to and including the 6(th) edition of the American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) edition staging system, ICC was staged the same as hepatocellular carcinoma. In the 7(th) edition AJCC/UICC manual, the staging system of ICC was revised such that a distinct classification was proposed. Pathologic features for prognosis included vascular invasion, tumor multiplicity, local extension, periductal infiltration and lymph nodal metastasis...

Intrahepatic cholangiocarcinoma (ICC) is a rare disease and carries a poor prognosis with surgery remaining the only curative treatment option. However, due to the late presentation of symptoms and close proximity of the tumors to central hepatic structures, only about 30% of patients are classified eligible to resection. As for palliative approaches, ICC constitutes a possible indication for loco-regional therapies (LRT). As such, intra-arterial therapies (IAT) are reported to be feasible, safe and effective in inducing tumor response in unresectable ICC...
