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...

Biliary tumors showing intraductal papillary growth (Pap-BT) include intraductal papillary neoplasm of the bile duct (IPNB) and papillary cholangiocarcinoma (CC). A differential diagnosis between IPNB and papillary CC currently remains challenging. The aim of the present study is to identify histological features and immunohistochemical markers of malignant potential such as tumor invasion in Pap-BT. Subjects comprised 37 patients with Pap-BT (intrahepatic and perihilar (proximal), 27; 17 non-invasive and 10 invasive); distal 10, all invasive)...

Menin (MEN1) is a tumor-suppressor protein in neuroendocrine tissue. Because cholangiocytes can take on a neuroendocrine phenotype, we tested the novel hypothesis that menin regulates cholangiocarcinoma proliferation. Menin and miR-24 expression levels were measured in the following intrahepatic and extrahepatic cholangiocarcinoma (CCA) cell lines, Mz-ChA-1, TFK-1, SG231, CCLP, HuCCT-1, and HuH-28, as well as the nonmalignant human intrahepatic biliary line, H69. miR-24 miRNA and menin protein levels were manipulated in vitro in Mz-ChA-1 cell lines...

Biliary adenofibromas (BAFs) are rare, benign biliary cystic tumors with potential for malignant transformation. Of the eleven prior cases of BAF reported in the literature, six showed evidence of malignant transformation. We describe the clinical, imaging and pathology features of two cases of malignant BAF and review the existing literature to raise awareness of this entity and provide additional tools for diagnosing this rare tumor Additionally, we identified a loss of function mutation in the cyclin-dependent kinase inhibitor 2A (CDKN2A) tumor suppressor gene in a malignant caudate lobe BAF, thereby providing potential insight into the molecular pathogenesis of BAF malignant transformation...

BACKGROUND: Patients with metastatic disease of the liver can have hyperbilirubinemia due to a number of reasons, including biliary obstruction. The purpose of this study was to analyze patient outcomes after percutaneous biliary drainage (PBD) catheter insertion in patients with extensive hepatic metastatic tumor burden. METHODS: Out of 746 PBD insertions, 44 patients (24 males, 20 females, mean age 57.4 years, range, 34-80 years) had metastatic malignancy with a hepatic tumor burden of greater than 20% parenchymal volume based on pre-procedure computed tomography (CT) or magnetic resonance imaging (MRI)...

RATIONALE: Von Hippel-Lindau (VHL) disease is a rare inherited, autosomal-dominant syndrome caused by heterozygous germline mutations in the VHL gene. VHL patients are prone to develop benign and malignant tumors and cysts in multiple organ systems involving kidneys, pancreas and central nervous system (CNS). The varied and complex clinical manifestations and radiological findings of VHL are of interest. PATIENT CONCERNS: We report a 38-year-old woman with a ten-year history of VHL disease involving both pancreas and biliary system...

OBJECTIVE: To identify predictive factors for gastroduodenal bleeding after postoperative radiation therapy in patients with biliary tract cancer. METHODS: We identified 186 patients with biliary tract cancer who completed scheduled postoperative radiation therapy from March 2000 to August 2013. To isolate the effects of radiation on gastroduodenal bleeding, patients with pylorus-preserving pancreaticoduodenectomy, pylorus-resecting pancreaticoduodenectomy or Whipple surgery (n = 67) were excluded from this analysis...

Gallbladder cancer is the most common malignancy of the biliary tract. Usually seen in advanced stages. There are still many controversies about the type of curative surgical treatment for each stage of the disease. The only chance of long term survival for patients with advanced tumors is aggressive, large surgeries that implies multiorgan resection.We report the case of a patient with gallbladder cancer with jaundice at diagnosis, who underwent extended hepatectomy (segment IV B, segment I and extra hepatic hilar bile duct included)...

BACKGROUND AND AIM: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal types of cancer; most patients die during the first 6 months after diagnosis. With a 5% 5-year survival rate, is the fourth leading cause of cancer death in developed countries. In this regard, several clinical, histopathologic and biological characteristics of the disease favoring long-term survival after pancreaticoduodenectomy have been reported to be significant prognostic factors. Despite the availability of this information, there is no consensus about the different prognostic factors reported in the literature, probably due to variations in patient selection, methods, and sample size studied...

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...

BACKGROUND: Obstructive jaundice is a common presenting symptom among patients with pancreatic cancer. While benefits of preoperative biliary drainage have been suggested by previous studies, recent evidence has shown no significant improvements of preoperative biliary drainage on the postoperative outcome but rather an increase of complications. There is no clear consensus on whether to treat malignant obstructive jaundice with preoperative biliary drainage prior to operative intervention or to proceed directly to resection...

There is ongoing discussion regarding the indications and timing of LT for patients with a preexisting extrahepatic malignancy. We herein report a pediatric case that underwent LDLT after therapy for YST. The patient, a 13-year-old female with biliary atresia, had undergone portoenterostomy at 2 months of age. She developed a left ovarian tumor with a high serum alpha-fetoprotein concentration at 10 years of age. She underwent left oophorectomy and was diagnosed with ovarian YST (Stage I). After surgery, hepatopulmonary syndrome progressed gradually...

BACKGROUND: Intestinal malrotation is a well-known anomaly in the normal rotation process of the midgut during embryogenesis. Multiple forms are described, resulting in various positional configurations of the small bowel and colon. Replaced common hepatic artery is a rare but not anecdotic variant of the standard hepatic vascularization, associated with surgical implications. Our aim is to explain the impact of their simultaneous presence during this procedure and the difficulty in identifying them preoperatively, despite imaging...

The objective of this work was to investigate the mechanisms of hepatobiliary toxicity caused by thienopyrimidone MCHR1 antagonists using BMS-773174 as a tool molecule. Co-administration of the pan CYP inhibitor 1-aminobenzotriazole with BMS-773174 prevented hepatobiliary damage, and direct delivery of the diol metabolite BMS-769750 caused hepatobiliary toxicity, identifying the diol and possibly its downstream hydroxyacid (BMS-800754) metabolite as the toxic species. Rat liver gene expression revealed treatment-related changes in hepatic transporters and induction of oval cell-specific genes including deleted malignant tumor 1 (Dmbt1)...

INTRODUCTION: Focal Nodular Hyperplasia (FNH) is the second most common benign tumor of the liver. Clinically FNH is asymptomatic and discovered incidentally . The pathogenesis is unclear; FNH is usually asymptomatic. When the tumor is large, it may be painful. Surgery is recommended only in the case of complications such as compression of adjacent organs, lesion progression with tumor size >5cm and presence of symptoms. PRESENTATION OF CASE: A 30 years old man, was evaluated during a routine visit, for diffuse abdominal pain and weight loss; Abdominal ultrasound showed no evidence of biliary obstruction but the US shows a hypoechoic, well defined focal lesion in the left liver...
