OBJECTIVES: To report our cancer center experience in the biliary tumors incidence other than cholangiocellular-carcinoma (CCC), emphasizing the radiological features. METHODS: 197 patients with biliary disease undergoing Gd-EOB-DTPA-enhanced MRI were reviewed. Four radiologists evaluated retrospectively size, structure, anatomical site, and signal intensity of lesions on MRI. Enhancement-pattern during the arterial-, portal-, and late-phase on US, CT and MR study was assessed as well as the enhancement pattern during the hepatobiliary-phase on MRI...

AIM: To examine the influence on apoptotic mechanisms following inhibition of polo-like kinases as therapeutically approach for cholangiocellular cancer treatment. METHODS: As most cholangiocarcinomas are chemotherapy-resistant due to mechanisms preventing tumor cell death, we investigated the effect of Cisplatin on cholangiocellular carcinoma (CCA) cell lines KMCH-1 and Mz-Ch-1. Polo-like kinases (PLK) are important regulators of the cell cycle and their inhibition is discussed as a potential therapy while PLK inhibition can regulate apoptotic mediators...

We described magnetic resonance (MR) features of peribiliary metastasis and of periductal infiltrative cholangiocarcinoma. We assessed 35 patients, with peribiliary lesions, using MR 4-point confidence scale. T1-weighted (T1-W), T2-weighted (T2-W) and diffusion-weighted images (DWI) signal intensity, enhancement pattern during arterial, portal, equilibrium and hepatobiliary phase were assessed. We identified 24 patients with periductal-infiltrating cholangiocellular carcinoma. The lesions in 34 patients appeared as a single tissue, while in a single patient, the lesions appeared as multiple individual lesions...

MicroRNAs (miRNAs) are small RNAs regulate gene expression by inhibiting the turnover of their target mRNAs. In the last years, it became apparent that miRNAs are released into the circulation and circulating miRNAs emerged as a new class of biomarkers for various diseases. In this review we summarize available data on the role of circulating miRNAs in the context of acute and chronic liver diseases including hepatocellular and cholangiocellular carcinoma. Data from animal models are compared to human data and current challenges in the field of miRNAs research are discussed...

High mobility group A1 (HMGA1) protein has been described to play an important role in numerous types of human carcinoma. By the modulation of several target genes HMGA1 promotes proliferation and epithelial-mesenchymal transition of tumor cells. However, its role in cholangiocarcinoma (CCA) has not been addressed yet. Therefore, we determined HMGA1 mRNA expression in CCA samples in a transcriptome array (n=104) and a smaller cohort (n=13) by qRT-PCR. Protein expression was evaluated by immunohistochemistry in a tissue microarray (n=67)...

BACKGROUND/AIM: The behavior of tumor markers in biliary tract malignancies is not well-known and has been scarcely studied. Such markers could play important roles in diagnostic and prognostic schemes as well as in decision-making about the best treatment strategies. This study analyzed the preoperative serum levels of conventional tumor markers (AFP, CEA, CA 19-9, CA 72-4), proliferative marker thymidine kinase (TK) and cytokeratins (TPA, TPS and CYFRA 21.1) in patients with gallbladder carcinoma, bile duct carcinoma (Klatskin) and cholangiocellular carcinoma, in relation to the patient prognosis...

Introduction. Most investigations on autoimmune pancreatitis (AIP) were published on Asian cohorts while those on Caucasians are limited. However, there might be differences related to the origin. Patients and Methods. We analyzed 36 patients and compared type 1 (AIP1) with type 2 (AIP2). Results. The majority of patients suffered from AIP1 (55.6%). AIP1 patients were significantly older than AIP2 patients (54.4 versus 40.8 years). Moreover, 85.0% of AIP1 patients had concurrent autoimmune cholangitis (AIC) while 18...

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...

A 50-year-old woman had a 12mm liver tumor at segment 4 and was diagnosed with hemangioma. Two years later, the liver tumor had grown to 27mm in diameter, and a new pancreatic tumor was detected using CT examination. The pancreatic tumor was suspected of being pancreatic carcinoma, based on the results of endoscopic-ultrasound-guided fine-needlebiopsy( EUS-FNA)of the pancreas. The liver tumor was diagnosed as adenocarcinoma using liver biopsy. Because of its slow growth and the solitary liver tumor, synchronous pancreatic cancer and intrahepatic cancer were suspected...

A 74-year-old man underwent pancreaticoduodenectomy for intraductal pupillary mucinous neoplasm(IPMN)of the pancreatic head. Histopathological examination of the specimen revealed non-invasive intraductal papillary mucinous carcinoma( IPMC). Two years after surgery, recurrent IPMN developed in the remnant pancreas, and a liver tumor was identified in S8 of the liver. The patient underwent total pancreatectomy of the remnant pancreas and partial resection of S8. These tumors were histopathologically diagnosed as invasive IPMC and hepatocellular carcinoma, respectively...

Cholangiocarcinoma, also referred to as cholangiocellular carcinoma (particularly in Japan), develops along the biliary tract. The tumor may be intra- or extrahepatic and have different features with specific treatments based on the site of origin. Guidelines for diagnosis and management of cholangiorcarcinoma, such as those proposed by EASL (European Association for the Study of the Liver)(1) and the Mayo Clinic(2) classify the tumor into intrahepatic, perihilar, and distal cholangiocarcinoma. There are three main macroscopic patterns of growth of cholangiocarcinoma: mass-forming, periductal-infiltrating and intraductal...
