Cholangiocarcinoma: The Next Asbestos-Related Disease?
Researchers from the University of Bologna noted that many of their cholangiocarcinoma patients had a history of asbestos exposure. In a recent study to further investigate the correlation, they found that asbestos exposure may be an occupational risk factor for cholangiocarcinoma. (Source: Asbestos and Mesothelioma News)

Aminolevulinic acid derivatives-based photodynamic therapy in human intra- and extrahepatic cholangiocarcinoma cells.
Abstract Hexyl-aminolevulinic acid (HALA) was compared with aminolevulinic acid (ALA) in terms of improving ALA-based photodynamic therapy (PDT) for human intra- and extrahepatic cholangiocarcinoma (CCA) HuCC-T1 and SNU1196 cells. Because of the different uptake mechanisms of HALA, a relatively higher amount of protoporphyrin IX (PpIX) was induced in the both CCA cell types at low concentrations of HALA. Furthermore, higher expression of porphobilinogen deaminase, coproporphyrinogen III oxidase, and protoporphyrinogen oxidase, the key enzymes for synthesizing PpIX in the heme biosynthetic pathway, facilitated the e...

The mTOR pathway in hepatic malignancies
Abstract The mechanistic/mammalian target of rapamycin (mTOR) pathway plays a critical role in cellular metabolism, growth and proliferation, and has been evaluated as a target for therapy in various malignancies. The mTOR pathway is a major tumor‐initiating pathway in hepatocellular carcinoma, with upregulation seen in up to 50% of (HCC) tumors. Metformin, which represses mTOR signaling by activating AMPK, has been shown to decrease liver carcinogenesis in population studies. mTOR inhibitors such as everolimus have been evaluated as adjunctive chemotherapy with some success, although efficacy has been limited by the lac...

Preoperative Hepatobiliary Imaging: What Does the Radiologist Need to Know?
Accurate preoperative reporting is essential in guiding the surgeon in deciding when and how to operate safely and effectively. Critically, this relies on an understanding of the operative issues faced by the surgeon, which is not always appreciated by the radiologist. This paper therefore aims to address this, first focusing on relevant anatomical variants, and then issues specific to laparoscopic cholecystectomy, hepatic transplantation, and finally hepatic resection (including cholangiocarcinoma resection). Throughout the paper, there is an emphasis on associated surgical techniques to add context to the discussion. (So...

67-kDa laminin receptor increases cGMP to induce cancer-selective apoptosis
The 67-kDa laminin receptor (67LR) is a laminin-binding protein overexpressed in various types of cancer, including bile duct carcinoma, colorectal carcinoma, cervical cancer, and breast carcinoma. 67LR plays a vital role in growth and metastasis of tumor cells and resistance to chemotherapy. Here, we show that 67LR functions as a cancer-specific death receptor. In this cell death receptor pathway, cGMP initiated cancer-specific cell death by activating the PKCδ/acid sphingomyelinase (PKCδ/ASM) pathway. Furthermore, upregulation of cGMP was a rate-determining process of 67LR-dependent cell death induced by the ...

Asia‐Pacific consensus recommendations for endoscopic and interventional management of hilar cholangiocarcinoma
Abstract Hilar cholangiocarcinoma (HCCA) is one of the most common types of hepatobiliary cancers reported in the world including Asia Pacific region. Early HCCA may be completely asymptomatic. When significant hilar obstruction develops, the patient presents with jaundice, pale stools, dark urine, pruritus, abdominal pain, and sometimes fever. Since no single test can establish the definite diagnosis then a combination of many investigations such as tumour markers, tissue acquisition, CT scan, MRI/MRCP, EUS/IDUS, and advanced cholangioscopy is required. Surgery is the only curative treatment. Unfortunately, the majority o...

Therapeutic Deletion of CAFs in Cholangiocarcinoma
Cancer-associated fibroblasts (CAF) are abundant in the stroma of desmoplastic cancers where they promote tumor progression. CAFs are “activated” and as such may be uniquely susceptible to apoptosis. Using cholangiocarcinoma as a desmoplastic tumor model, we investigated the sensitivity of liver CAFs to the cytotoxic drug navitoclax, a BH3 mimetic. Navitoclax induced apoptosis in CAF and in myofibroblastic human hepatic stellate cells but lacked similar effects in quiescent fibroblasts or cholangiocarcinoma cells. Unlike cholangiocarcinoma cells, neither CAF nor quiescent fibroblasts expressed Mcl-1, a known resistance...

Human liver carboxylesterase 1 outperforms alpha‐fetoprotein as biomarker to discriminate hepatocellular carcinoma from other liver diseases in Korean patients
Abstract Although alpha‐fetoprotein is currently the major serologic biomarker for hepatocellular carcinoma (HCC), it cannot efficiently distinguish this cancer from other forms of liver disease in early diagnosis due to its low sensitivity. The aim of this study is to compare human carboxylesterase 1 (hCE1) biomarker sensitivity and specificity versus alpha‐fetoprotein (AFP). Antibody‐based assays for hCE1 and AFP were used to test both biomarkers with respect to diagnostic efficiency, Youden's index, and the area under the curve (AUC) through receiver operating characteristic (ROC) analysis in plasma from 208 patie...

Hepatocyte nuclear factor 4 alpha deletion promotes diethylnitrosamine‐induced hepatocellular carcinoma in mice
Abstract HNF4α, the master regulator of hepatocyte differentiation, has been recently shown to inhibit hepatocyte proliferation via unknown mechanisms. We investigated the mechanisms of HNF4α‐induced inhibition of hepatocyte proliferation using a novel TAM‐inducible, hepatocyte specific HNF4α knockdown mouse model. Hepatocyte specific deletion of HNF4αin adult mice resulted in increased hepatocyte proliferation with a significant increase in liver to body weight ratio.

Activation of mTORC1 and Raf/Pyk2 by growth factor‐mediated EphA2 Is required for cholangiocarcinoma growth and metastasis
We examined the biological role of EphA2 in tumor growth and metastasis in CC tissues and cells according to the degree of differentiation and we explored the downstream signaling pathways of EphA2. Growth factor‐mediated EphA2 over‐expression itself leads to the activation of the mTORC1 and ERK pathways through ligand−independent activation of EphA2 (phosphorylation of S897). An in vitro soft agar assay and in vivo orthotopic or subcutaneous tumor model showed that EphA2 enhanced colony formation and accelerated tumor growth and, which seemed to be mainly associated with Akt (T308)/mTORC1 activation.

Palliative management plays an important role in the treatment of patients with inoperable hilar cholangiocarcinoma. Surgical, percutaneous, and endoscopic biliary drainage are three modalities available to resolve obstructive jaundice. Plastic stents were widely used in the past; however, self-expanding metal stents (SEMS) have become popular recently due to their long patency and reduced risk of side branch obstruction, and SEMS are now the accepted treatment of choice for hilar cholangiocarcinoma.

Is a self-expandable metal stent better than a plastic stent in unresectable complex hilar cholangiocarcinoma with regard to the adequacy of drainage and survival of the patients?
We read with great interest the recent article by Sangchan et al. The authors concluded that endoscopic biliary drainage with a self-expandable metal stent (SEMS) provides better adequacy of drainage and longer survival compared with the plastic stent (PS) in patients with unresectable complex hilar cholangiocarcinoma. It is an interesting study. Nevertheless, several issues seem worthy of comment. (Source: Gastrointestinal Endoscopy)

Cholangiocarcinoma: Are North American Surgical Outcomes Optimal?
Conclusions: This analysis suggests that postoperative outcomes are best for distal and worst for perihilar cholangiocarcinomas, and hepatectomy for bile duct cancers is associated with a 2- to 3-fold mortality risk. We conclude that North American surgical outcomes can be improved for patients with proximal cholangiocarcinomas. (Source: Journal of the American College of Surgeons)
