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...

Gemcitabine-based therapy remains the mainstay of treatment for patients with biliary tract cancers (BTCs) with no second-line treatment(s) established yet. Aberrant activation of MAPK pathway in patients with BTC indicates its importance in BTC. Trametinib is a potent, highly selective, allosteric non-competitive inhibitor of MEK1/MEK2. In this Phase IIa open-label, single-arm study, we investigated efficacy and safety of trametinib in Japanese patients with advanced BTC refractory to gemcitabine-based therapy...

Treatment with cisplatin with gemcitabine (CG) demonstrates a survival benefit in patients with advanced biliary tract cancer (ABTC). However, the weekly administration can add significant toxicities that may prohibit prolonged treatment. Based on previous studies, we implemented a modified biweekly regimen of GC in an attempt to optimize the prescribed regimen with an improved toxicity profile, added convenience to patients while maintaining efficacy. Patients with ABTC were treated with fixed dose rate (FDR) gemcitabine (1000mg/m(2) /min) and cisplatin 20mg/m(2) on days 1 and 15 of every 28-day cycle...

Cholangiocarcinoma is a rare type of cancer which is an increasingly discernible health threat. The disease is usually very difficult in diagnosis and various treatment modalities are typically not effective. Cholangiocarcinoma is a complex and very heterogeneous malignancy characterized by tumor location, different risk factors, molecular profiling, and prognosis. Cancer cell lines represent an important tool for investigation in various aspects of tumor biology and molecular therapeutics. We established two cell lines, KKU-452 and KKU-023, which were derived from patients residing in the endemic area of liver fluke infection in Thailand...

Interferon regulatory factor 1 (IRF1) has been suggested to act as a tumor suppressor in human cancers. However, the clinical significance and biological function of IRF1 in cholangiocarcinoma is poorly understood. In our results, IRF1 mRNA and protein expressions were decreased in cholangiocarcinoma tissues and cell lines compared with paired normal hepatic tissues and intrahepatic bile duct epithelial cell line. IRF1 protein low-expression was associated with tumor stage, tumor size, vascular invasion and metastasis and served as a poor independent prognostic parameter in cholangiocarcinoma patients...

We report the case of a 71-year-old man with afferent loop obstruction (ALO) after Roux-en-Y reconstruction due to gastric cancer. Computed tomography showed a distended afferent loop and a dilatated bile duct. We could not reach the stricture site in the afferent loop using a gastroscope. We performed percutaneous transhepatic biliary drainage (PTBD) and placed a self-expanding metallic stent (SEMS) in the duodenal stricture through the PTBD route. Although an endoscopic approach is preferable, when PTBD can be performed, percutaneous transhepatic SEMS placement might be an alternative option for treating ALO in cases in which it is not possible to reach the site of stenosis with an endoscope...

OBJECTIVE: To examine potential ethnic disparities in cancer incidence and survival rates among the oldest old using data from the SEER Program. DESIGN: Cases diagnosed with one of the leading four cancer sites (lung and bronchus, colon and rectum, female breast, prostate) and four cancer sites (stomach, liver and intrahepatic bile duct, gallbladder, and cervical) that disproportionally affect Hispanics were reported to one of 18 SEER registries. Differences in cancer incidence were examined for cases aged ≥85 years diagnosed during the most recent 5-year time period (2009-2013) and, to examine changes over time, from 1992 to 2013...

Photodynamic therapy (PDT) is a method used treat tumors via utilizing photodynamic reactions between photosensitive substances with tumor affinity and lasers. For overall bile duct cancers, PDT has been demonstrated to resolve stenosis and improve prognosis; however, when limited to intrahepatic bile duct cancers, modifications to the laser irradiation are necessary as surrounding hepatocytes incorporate a large amount of photosensitive substances. Furthermore, the intrahepatic bile duct is thin, and a guide sheath and thin fiber are necessary to transport laser irradiation probes to the target region...

BACKGROUND: Bile duct cancers (BTCs) are highly aggressive tumors with a dismal prognosis and an increasing incidence. BTC is a tumorbiologically and clinically heterogeneous tumor group and can be subdivided according to anatomical aspects into intrahepatic cholangiocarcinomas (iCCA), extrahepatic cholangiocarcinomas (eCCA) and gallbladder carcinomas (GBC). NEW THERAPY OPTIONS: Chronic inflammatory processes of the biliary system seem to play a role in the development of these tumors...

PURPOSE: To increase the surgical opportunities for locally advanced perihilar bile duct cancers that require left-sided hepatectomies, we developed the transparenchymal glissonean approach (TGA); it comprises intra-hepatic exposure and dissection of the Glisson's sheath to gain access to the hepatic artery and portal vein for reconstruction. METHODS: Following skeletonization of the hepatoduodenal ligament, the proximal portions of invaded vessels are exposed. If extra-hepatic attempts to access the distal portions of the invaded vessels fail, TGA can be used...

Bile acids have been implicated in the development of gastrointestinal malignancies. Both the specific nature of individual bile acids and their concentration appear key factors in the carcinogenic potency of bile. Using liquid chromatography mass spectrometry (LC-MS) we performed quantitative profiling of bile extracted directly from the common bile duct in 30 patients (15 patients with pancreatic cancer and 15 patients with benign disease). Separation and detection of bile acids was performed using a 1.7μm particle size reversed-phase C18 LC column at a flow rate of 200μL/min with negative electrospray ionization MS...

Biliary cancers include gallbladder cancer (GBC) and cholangiocarcinoma (CCA). GBC may appear as a mass replacing the gallbladder, thickened gallbladder wall, or polypoid lesion in the gallbladder. Gallbladder polyps with low risk of GBC (eg, 6- to 10-mm polyps without other risk factors) are screened with sonography. In general, polyps smaller than 5 mm are ignored and those larger than 10 mm require surgical consideration. Screening for CCA is less well-established. On imaging, CCA may be divided into mass-forming, periductal infiltrating, and intraductal types...

Hepatic fibrosis is a potential health problem that may end with life-threatening cirrhosis and primary liver cancer. Recent studies point out to the protective effects of silent information regulator1 (SIRT1), against different models of organs fibrosis. This work aimed to investigate the possible protective effect of sildenafil (SIRT1 activator) against hepatic fibrosis induced by bile duct ligation (BDL). Firstly, three different doses of sildenafil (5, 10, 20mg/kg/day) were investigated; to detect the most protective one against BDL induced liver dysfunction and hepatic fibrosis...
