BACKGROUND: The prognosis of patients with different gastrointestinal cancers varies widely. Despite advances in treatment strategies, such as extensive resections and the addition of new drugs to chemotherapy regimens, conventional treatment strategies have failed to improve survival for many tumours. Although promising, the clinical application of molecularly guided personalized treatment has proven to be challenging. This narrative review focuses on the personalization of cancer therapy using patient-derived three-dimensional 'organoid' models...

BACKGROUND: In biliary tract cancer treatment, a precise preoperative evaluation of the patient's liver function is essential to avoid post-hepatectomy liver failure (PHLF) and mortality. The present study aimed to evaluate the role of the Albumin-Indocyanine Green Evaluation (ALICE) grading system in predicting PHLF in biliary tract cancer patients. METHODS: Data from 166 patients who underwent hepatectomy for biliary tract cancer between 2000 and 2016 were retrospectively analyzed...

As the most common and most important cancer of the pancreas, with rapid mortality and now also as the third leading cause of cancer-related deaths in the United States, pancreatic ductal adenocarcinoma (PDAC) has become synonymous with "pancreas cancer". PDAC is also the prototype of the "pancreatobiliary-type" adenocarcinomas, along the biliary tract, ampullary and gallbladder cancers with the similar morphology and behavior. Recent molecular profiling studies have identified distinct subsets of PDAC, potentially with different behaviors and targetability...

BACKGROUND: Experiences at specialized hepatobiliary centers have demonstrated efficacy of minimally invasive liver resection, but concerns exist regarding whether these procedures would remain effective once disseminated to a broad range of clinical practices. We sought to present the first comparison of MILR and open liver resection (OLR) for primary liver malignancy from a nationally representative cancer registry. METHODS: Cases of liver and intrahepatic bile duct cancer were identified from the National Cancer Data Base Participant Use File...

Pancreatic ductal adenocarcinoma (PDAC) continues to carry the lowest survival rates among all solid tumors. A marked resistance against available therapies, late clinical presentation and insufficient means for early diagnosis contribute to the dismal prognosis. Novel biomarkers are thus required to aid treatment decisions and improve patient outcomes. We describe here a multi-omics molecular platform that allows for the first time to simultaneously analyze miRNA and mRNA expression patterns from minimal amounts of biopsy material on a single microfluidic TaqMan Array card...

BACKGROUND: Gallbladder cancer is the most common malignant cancer of the bile ducts and third most common gastrointestinal malignant in the world for public health. Its relatively low incidence and confused symptoms result in advanced disease at the time of presentation, contributing to poor prognosis and reduced survival associated with this disease. The main function of the gallbladder is to store excreted bile acids from the liver in preparation for a meal. Its main risk factor is prolonged exposure to biliary calculations, although bacterial infections and other inflammatory conditions are associated...

BACKGROUND: Portal vein embolization is essential for patients with biliary cancer who undergo extended hepatectomy to induce hypertrophy of the future remnant liver. Over 830 patients have undergone the portal vein embolization at our institution since 1990. Non-alcoholic fatty liver disease is an entity of hepatic disease characterized by fat deposition in hepatocytes. It has a higher prevalence among persons with morbid obesity, type 2 diabetes, and hyperlipidemia. Neither the mechanism of hepatic hypertrophy after portal vein embolization nor the pathophysiology of non-alcoholic fatty liver disease has been fully elucidated...

Early B cell factor 1 (EBF1) is a transcription factor involved in the differentiation of several stem cell lineages and it is a negative regulator of estrogen receptors. EBF1 is down-regulated in many tumors, and is believed to play suppressive roles in cancer promotion and progression. However, the functional roles of EBF1 in carcinogenesis are unclear. Liver fluke-infection-associated cholangiocarcinoma (CCA) is an oxidative stress-driven cancer of bile duct epithelium. In this study, we investigated EBF1 expression in tissues from CCA patients, CCA cell lines (KKU-213, KKU-214 and KKU-156), cholangiocyte (MMNK1) and its oxidative stress-resistant (ox-MMNK1-L) cell lines...

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 and gemcitabine 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 (1,000 mg/m2 /min) and cisplatin 20 mg/m2 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...

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...

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...

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...
