:  Introduction and aims. Cholangiocarcinomas are a heterogeneous group of tumors that can be classified into three clinically distinct types of cancers, intrahepatic, perihilar and distal cholangiocarcinoma. The inconsistent use of nomenclature for these cancers has obscured a true knowledge of the epidemiology, natural history and response to therapy of these cancers. Our aims were to define demographic characteristics, management and outcomes of these three distinct cancer types. MATERIALS AND METHODS: A retrospective study of patients enrolled in an institutional cancer registry from 1992 to 2010...

Primary liver cancer is the second leading cause of cancer-related death worldwide and therefore a major public health challenge. We review hypotheses of the cell of origin of liver tumorigenesis, and clarify the classes of liver cancer, based on molecular features and how these affect patient prognosis. Primary liver cancer comprises hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (iCCA), and other rare tumors, notably fibrolamellar carcinoma and hepatoblastoma. The molecular and clinical features of HCC vs iCCA are distinct, although they have overlapping risk factors and pathways of oncogenesis...

OBJECTIVE: The objective of this study was to analyse the safety, feasibility and survival outcomes of our treatment of perihilar cholangiocarcinoma (PHC) since the introduction of more aggressive approaches (en bloc, vascular and extended liver resections) in 2007. PATIENTS AND METHODS: From July 2007 to December 2014, 32 consecutive patients with PHC underwent surgery with curative intent. Surgery with resection and reconstruction of the portal vein bifurcation and right hepatic artery was performed if necessary for a complete removal of the tumour...

Nodular sclerosing cholangiocarcinoma (NS-CCA) is a common CCA of the intrahepatic large, perihilar and distal bile ducts. Intraepithelial biliary neoplasms, such as the mucosal extension of carcinoma and pre-invasive neoplastic lesions (i.e. biliary intraepithelial neoplasia [BilIN]) reportedly occur in the bile ducts around CCA. In the present study, we collectively refer to these intraepithelial lesions as "intraepithelial neoplasms of the bile duct (IENBs)". We examined the IENBs in 57 surgically resected cases of NS-CCA...

BACKGROUND & AIMS: Adenocarcinomas of the pancreatobiliary system are currently classified by their primary anatomical location. In particular, the pathological diagnosis of intrahepatic cholangiocarcinoma is still considered as a diagnosis of exclusion of metastatic adenocarcinoma. Periampullary cancers have been previously classified according to the histological type of differentiation (pancreatobiliary, intestinal), but overlapping morphological features hinder their differential diagnosis...

REVIEW

Tumors of the pancreas, the ampulla of Vater, and the extrahepatic and intrahepatic bile ducts have significant histological similarities due to the common embryonic origin of the pancreatobiliary system. This obviates the need for discovery of biomarkers with diagnostic and prognostic value for these tumors. Mucins, especially MUC-1, -2, -4 and -5AC, are important candidates for developing into such reliable biomarkers. Increased expression of MUC1 occurs in pancreatic ductal adenocarcinomas and is associated with increased degrees of dysplasia in pancreatic intraepithelial neoplasia (PanIN)...

A bile duct lesion originating from intrahepatic bile ducts is generally regarded as an incidental pathologic finding in liver specimens. However, a recent study on the molecular classification of intrahepatic cholangiocarcinoma has focused on the heterogeneity of this carcinoma and has suggested that the cells of different origins present in the biliary tree may have a major role in the mechanism of oncogenesis. In this review, benign intrahepatic bile duct lesions-regarded in the past as reactive changes or remnant developmental anomalies and now noted to have potential for developing precursor lesions of intrahepatic cholangiocarcinoma-are discussed by focusing on the histopathologic features and its implications in clinical practice...

Intrahepatic cholangiocarcinoma (ICC) is usually confirmed in advanced stage at the time of diagnosis or after surgical exploration, however, indication of surgical treatment is usually controversial for ICC in advanced stages. This retrospective study aims to evaluate clinical value of surgery for such tumors, in order to identify the appropriate patients who will benefit from surgery, and to evaluate the prognostic accuracy of the current staging system for advanced ICC. From January 2007 to December 2011, 387 consecutive surgically treated patients with ICC in AJCC‑stage Ⅳ were evaluated...

Neuroendocrine carcinoma (NEC) originating from the gastrointestinal hepatobiliary-pancreas is a rare, invasive, and progressive disease, for which the prognosis is extremely poor. The patient was a 72-year-old man referred with complaints of jaundice. He was diagnosed with middle extrahepatic cholangiocarcinoma (cT4N1M0, cStage IV). He underwent a right hepatectomy combined with extrahepatic bile duct and portal vein resection after percutaneous transhepatic portal vein embolization. Microscopic examination showed a large-cell neuroendocrine carcinoma according to the WHO criteria for the clinicopathologic classification of gastroenteropancreatic neuroendocrine tumors...

BACKGROUND: AJCC staging system is unreliable for predicting survival in distal bile duct (DBD) cancer patients, due to inter-observer variation. Measured depth of invasion (DOI) is suggested to be more accurate to predict patients' clinical outcome in extra-hepatic cholangiocarcinomas, but its significance in DBD cancer and cutoff values are still debatable. This study aimed to identify the optimal cutoff value of DOI in relation to prognosis in DBD cancer patients. METHODS: Data of 179 patients with DBD adenocarcinoma treated in three institutions were investigated...

BACKGROUND: Seventh AJCC distal cholangiocarcinoma T-stage classification inadequately separates patients by survival. This retrospective study aimed to define a novel T-stage system to better stratify patients after resection. METHODS: Curative-intent pancreaticoduodenectomies for distal cholangiocarcinoma (1/2000-5/2015) at 10 US institutions were included. Relationships between tumor characteristics and overall survival (OS) were assessed and incorporated into a novel T-stage classification...

AIMS: The aim of this study was to achieve a better definition of intraductal papillary neoplasms of the bile duct (IPNBs). METHODS AND RESULTS: Biliary tumours that showed predominantly intraductal papillary growth were provisionally classified as IPNBs (n = 25) and papillary cholangiocarcinomas (n = 27). IPNB was defined as a neoplasm that is confined to the epithelium or is regularly arranged in a high-papillary architecture along thin fibrovascular stalks, whereas the term 'papillary cholangiocarcinoma' was used for tumours with more complex papillary structures (e...
