A number of benign and malignant neoplasms may arise from the vascular elements within the liver parenchyma. Lesions discussed in this article include angiosarcoma, epithelioid hemangioendothelioma, solitary fibrous tumor (hemangiopericytoma), infantile, and cavernous hemangiomas. Despite a common theme of vascular origin, the pathologic and imaging appearance of these entities can be heterogeneous. Angiosarcomas are bizarrely enhancing, highly aggressive tumors, which often present with metastatic disease...

REVIEW
Pedro Cabral Correia, Bruno Morgado
Caroli's disease is a very rare congenital malformation, currently included in cystic diseases of the biliary tract, and is characterized by ectasia and dilatation of the intrahepatic bile ducts. Two clinical entities can be distinguished, Caroli's disease in which congenital hepatic impairment is limited to cystic dilatation and Caroli's syndrome in which congenital hepatic fibrosis coexists. We present two cases of atypical presentations of Caroli's disease. Case one was a 76-year-old man who was referred to our hospital for chronic non-remitting epigastric pain prior to diagnosis...

BACKGROUND: Seaweeds have a long history of use in Asian countries as functional foods, medicinal herbs, and the treatment of cancer. Polysaccharides from various seaweeds have shown anti-tumor activity. Cholangiocarcinoma (CCA), often with metastatic disease, is highly prevalent in Thailand as a consequence of liver fluke infection. Recently, we extracted sulfated galactans (SG) from Gracilaria fisheri (G. fisheri), a south east Asian seaweed, and found it exhibited anti-proliferation effect on CCA cells...

BACKGROUND AND AIM: Endoscopic nasobiliary drainage (ENBD) is often recommended in preoperative biliary drainage (PBD) for hilar malignant biliary obstruction (MBO) but endoscopic biliary stent (EBS) is also used in the clinical practice. We conducted this large scale multicenter study to compare ENBD and EBS in this setting. METHODS: A total of 374 cases undergoing PBD including 281 ENBD and 76 EBS for hilar MBO in 29 centers were retrospectively studied. RESULTS: Extrahepatic cholangiocarcinoma (ECC) accounted for 69...

BACKGROUND & AIMS: To examine the impact of antiviral therapy (AVT) on survival outcomes after liver resection (LR) for intrahepatic cholangiocarcinoma (ICC) patients with underlying HBV infection. METHODS: Data on 928 ICC patients with HBV infection who underwent LR at two medical centers between 2006 and 2011 were analyzed. Data on viral reactivation, tumor recurrence, cancer-specific survival (CSS) and overall survival (OS) were obtained. Survival rates were analyzed using the time-dependent Cox regression model adjusted for potential covariates...

Cholangiocarcinoma remains the second most prevalent hepatic neoplasm in the United States with a 5-year survival rate of less than 10%. Currently, no systemic therapy has demonstrated efficacy. Therefore, an urgent need for the identification of molecularly targeted compound(s) remains. The Notch signaling pathway has been shown to be dysregulated in cholangiocarcinoma, exhibiting hyperactivity while also possibly mediating chemotherapeutic resistance. We analyzed the effects of xanthohumol, a prenylated chalcone, on cholangiocarcinoma proliferation utilizing human cholangiocarcinoma cell lines CCLP1, SG-231 and CC-SW-1 while gaining insight into the associated mechanism...

Although intrabiliary metastasis of carcinoma in the liver is unusual, intraductal and/or intraepithelial spread of cancer cells along intrahepatic bile ducts is now well recognized as hepatic metastasis. However, several clinical and laboratory findings, including images, lead us to differentially diagnose from primary intrahepatic cholangiocarcinoma. We report here on a case of colonic adenocarcinoma that metastasized to the liver with spread along with the intrahepatic bile duct of S5/6 area. The patient was a 51-year-old man and clinically diagnosed liver metastasis of sigmoid colon cancer (tub2, pMP, ly1, v0, n0), which was diagnosed and treated by sigmoidectomy 7 years ago...

Cholangiocarcinoma (CCA) is a fatal disease with a five-year survival of <30%. For a majority of patients chemotherapy is the only therapeutic option, and virtually all patients relapse. Gemcitabine is the frontline agent for treatment of CCA. Patients treated with gemcitabine monotherapy survive ~8 months. Combining this agent with cisplatin increases survival by ~3 months, but neither regimen produces durable remissions. The molecular etiology of this disease is poorly understood. To facilitate molecular characterization and development of effective therapies for CCA, we established a panel of patient-derived xenograft (PDX) models of CCA...

Methionine adenosyltransferase genes encode enzymes responsible for the biosynthesis of S-adenosylmethionine, the principal biological methyl donor and precursor of polyamines and glutathione. Mammalian cells express three genes - MAT1A, MAT2A, and MAT2B - with distinct expression and functions. MAT1A is mainly expressed in the liver and maintains the differentiated states of both hepatocytes and bile duct epithelial cells. Conversely, MAT2A and MAT2B are widely distributed in non-parenchymal cells of the liver and extrahepatic tissues...

Purpose: Even though the therapeutic gold standard of hilar cholangiocarcinoma(HCCA) resection is cancer-free resection margin(RM), surgical treatment still remains challenging. This study evaluated the prognostic significance of RM status in resected HCCA patients and identified survival prognostic factors. Materials and Methods: We reviewed records of 96 HCCA patients who underwent surgery from 2001 to 2012 and analyzed the RM status and prognostic factors that affecting survival...

AIM: The potential of biomarkers in detecting early cholangiocarcinoma (CCA) is facilitated by examining CCA-associated proteins from primary studies. One such protein is mucin 5AC (MUC5AC) but inconsistency of reported associations between its expression/serum levels and CCA prompts a meta-analysis to obtain more precise estimates. METHODS: A literature search yielded 17 included articles where multiple data in some raised the number of studies to 22. We calculated pooled odds ratios (OR) and 95% confidence intervals from negative and positive readings of MUC5AC levels...

The aim of the present study was to investigate the role of triglyceride metabolism in the effect of obstructive cholestasis on liver regeneration following 50% partial hepatectomy (PH). Obstructive cholestatic rat models were achieved via ligation of the common bile duct (BDL). Following comparisons between hepatic pathological alterations with patients with perihilar cholangiocarcinoma, rats in the 7 day post‑BDL group were selected as the BDL model for subsequent experiments. Liver weight restoration, proliferating cell nuclear antigen labeling index, cytokine and growth factor expression levels, and hepatic triglyceride content were evaluated to analyze liver regeneration post‑PH within BDL and control group rats...

Primary sclerosing cholangitis (PSC) is a chronic immune-mediated disease affecting intra- and extrahepatic bile ducts, primarily the large biliary ducts. Clinical manifestations are broad, and the spectrum encompasses asymptomatic cholestasis, icteric cholangitis with pruritis, cirrhosis, and cholangiocarcinoma. Though rare, PSC has a propensity to affect young to middle-aged males and is strongly associated with inflammatory bowel disease. There is an unmet need for effective medical treatments for PSC, and to date, the only curative therapy is liver transplantation reserved for those with end-stage liver disease...

Intrahepatic cholangiocarcinoma (ICC) arises from the biliary epithelium and is a relatively rare and highly fatal neoplasm. The prognosis is poor, and survival is limited to a few months. Here, we report a case of advanced ICC that was successfully treated with apatinib, a new oral tyrosine kinase inhibitor that targets the intracellular domain of vascular endothelial growth factor receptor-2. To the best of our knowledge, this is the first case report of the successful use of apatinib for advanced ICC; this treatment has demonstrated fewer toxic effects than traditional cytotoxic chemotherapy...

BACKGROUND: Whether perioperative blood transfusions (PBTs) adversely influence oncological outcomes for intrahepatic cholangiocarcinoma (ICC) patients after curative resection remains undetermined. METHODS: Of the 605 patients who underwent curative liver resection for ICC between 2000 and 2012, 93 received PBT. We conducted Cox regression and variable selection logistic regression analyses to identify confounding factors of PBT. Propensity score matching (PSM) and Cox regression analyses were used to compare the overall survival (OS) and disease-free survival (DFS) between the patients with or without PBT...
