BACKGROUND: European liver fluke Opisthorchis felineus, causing opisthorchiasis disease, is widespread in Russia, Ukraine, Kazakhstan and sporadically detected in the EU countries. O. felineus infection leads to hepatobiliary pathological changes, cholangitis, fibrosis and, in severe cases, malignant transformation of bile ducts. Due to absence of specific symptoms, the infection is frequently neglected for a long period. The association of opisthorchiasis with almost incurable bile duct cancer and rising international migration of people that increases the risk of the parasitic etiology of liver fibrosis in non-endemic regions determine high demand for development of approaches to opisthorchiasis detection...

Hereditary nonpolyposis colorectal cancer (HNPCC), also called Lynch syndrome, is an autosomal dominant cancer syndrome that confers an elevated risk of early-onset colorectal cancer (CRC) and increased lifetime risk for other cancers of the endometrium, stomach, small intestine, hepatobiliary system, kidney, ureter, and ovary. Lynch syndrome accounts for up to 3% of all CRC, making it the most common hereditary colorectal cancer syndrome. Germline mutations in methyl-directed mismatch repair (MMR) genes give rise to microsatellite instability (MSI) in tumor DNA...

LESSONS LEARNED: There continues to be a lack of systemic options for advanced hepatocellular carcinoma (HCC); sorafenib and, very recently, regorafenib are the only approved options. There exists a potential to combine sorafenib with chemotherapeutic agents shown to be active in HCC, such as capecitabine, safely.Good tumor response was observed, with objective improvement in a few patients seldom seen by single agent sorafenib; however, because of the limited number of patients, meaningful conclusions on survival cannot be drawn...

Cholangiocarcinoma (CCA) is a hepatobiliary malignancy exhibiting high incidence in countries with endemic liver-fluke infection. We analysed 489 CCAs from 10 countries, combining whole-genome (71 cases), targeted/exome, copy-number, gene expression, and DNA methylation information. Integrative clustering defined four CCA clusters - Fluke-Positive CCAs (Clusters 1/2) are enriched in ERBB2 amplifications and TP53 mutations, conversely Fluke-Negative CCAs (Clusters 3/4) exhibit high copy-number alterations and PD-1/PD-L2 expression, or epigenetic mutations (IDH1/2, BAP1) and FGFR/PRKA-related gene rearrangements...

Primary sclerosing cholangitis (PSC) is a rare obliterative fibrotic condition of the bile ducts. We assessed PSC epidemiology and natural history within the UK Clinical Practice Research Datalink (CPRD).Incidence and natural history of PSC were evaluated in a retrospective cohort study using linkage of CPRD, Hospital Episode Statistics, and Office for National Statistics data. Data from age, sex, and general practice-matched population controls provided a context for the incident PSC patients. Liver disease other than PSC was defined as autoimmune hepatitis, hepatitis, hepatomegaly, liver failure, cirrhosis, portal hypertension, cholangiocarcinoma, or hepatobiliary cancer...

Stauffer's syndrome is a rare paraneoplastic syndrome classically associated with renal cell carcinoma. It presents as abnormal hepatic panel in the absence of hepatic disease, which improves with treatment of the cancer and worsens with recurrence. Here, we describe a case of hepatic panel abnormalities in a patient with pancreatic cancer with no evidence of metastatic disease to the liver, primary hepatobiliary etiology, or clear offending medications. We believe this to be the first reported case of Stauffer's syndrome in patients with pancreatic cancer...

In 2007 the Cancer Care Ontario Hepatobiliary-Pancreatic (HPB) Community of Practice was formed during the wake of provincial regionalization of HPB services in Ontario, Canada. Despite being conceptualized within the literature as an educational intervention, communities of practice (CoP) are increasingly being adopted in healthcare as quality improvement initiatives. A qualitative case study approach using in-depth interviews and document analysis was employed to gain insight into the perceptions and attitudes of the HPB surgeons in the CoP...

Inhomogeneous heating by photothermal therapy (PTT) during cancer treatment often results in the recurrence of tumors. Thus, integrating PTT with chemotherapy (CHT) may provide a complementary treatment for enhanced therapeutic efficiency. Herein, this study develops a hollow structured polymer-silica nanohybrid (HPSN) as a nanocarrier to simultaneously deliver the anticancer drug paclitaxel and photothermal agent palladium phthalocyanine to tumors through enhanced permeation and the retention effect. A combinational CHT/PTT therapy on mice bearing aggressive tumor grafts is conducted...

We report the synthesis of a macrocyclic Gd chelate based on a 1,4,7,10-tetraazacyclododecane-1,4,7-trisacetic acid (DO3A) coordinationn cage bearing an ethoxybenzyl (EOB) moiety and discuss its use as a T1 hepatobiliary magnetic resonance imaging (MRI) contrast agent. The new macrocyclic liver agent shows high chelation stability and high r1 relaxivity compared with linear-type Gd chelates, which are the current clinically approved liver agents. Our macrocyclic, liver-specific Gd chelate was evaluated in vivo through biodistribution analysis and liver MRI, which demonstrated its high tumor detection sensitivity and suggested that the new Gd complex is a promising contrast agent for liver cancer imaging...

The human intestinal microbiome encompasses at least 100 trillion microorganisms that can influence host immunity and disease conditions, including cancer. Hepatobiliary and pancreatic cancers have been associated with poor prognosis owing to their high level of tumor invasiveness, distant metastasis, and resistance to conventional treatment options, such as chemotherapy. Accumulating evidence from animal models suggests that specific microbes and microbial dysbiosis can potentiate hepatobiliary-pancreatic tumor development by damaging DNA, activating oncogenic signaling pathways, and producing tumor-promoting metabolites...

Indoleamine and tryptophan 2,3-dioxygenases (IDO1 and TDO2) are pyrrolases catalyzing the oxidative cleavage of the 2,3-double bond of L-tryptophan in kynurenine pathway. In the tumor microenvironment, their increased activity prevents normal immune function, i.e. tumor cell recognition and elimination by cytotoxic T-cells. Consequently, inhibition of the kynurenine pathway may enhance the activity of cancer immunotherapeutics by reversing immune dysfunction. We sought to investigate the properties of radiolabeled 5-[(18)F]fluorotryptophan with respect to its ability for measuring IDO1 and TDO2 activity by positron emission tomography (PET)...

Pathologists are likely to encounter IgG4-related disease in several organ systems. This article focuses on helping pathologists diagnose IgG4-related disease in the hepatobiliary system. Missing the diagnosis can result in unnecessary organ damage and/or unnecessary surgical and cancer therapy. In the liver, tumefactive lesion(s) involving the bile ducts with storiform fibrosis and an IgG4-enriched lymphoplasmacytic infiltrate are highly concerning for IgG4-related disease. The recent identification of oligoclonal populations of T cells and B cells in IgG4-related disease may lead to molecular tests, new therapeutics, and a greater mechanistic understanding of the disease...

Sorafenib and cisplatin plus gemcitabine currently represent first-line treatment standards in advanced hepatocellular carcinoma and biliary cancer, respectively. Conventional cytotoxic agents (monotherapy or combination therapy) have demonstrated activity in the second-line setting or in those in which first-line agents are contraindicated. A strategy for safe yet effective administration of such systemic therapies in patients with advanced hepatobiliary cancer and abnormal liver function needs to be strongly considered...
