Active clinical trials for "Biliary Tract Neoplasms"

The purpose of this study is to determine if cholangioscopically-directed biopsies provide a higher diagnostic yield for malignancy in the setting of indeterminate biliary strictures when compared to standard means of sampling.

This is a study where fresh tumor tissue and blood samples will be collected from patients with advanced biliary tract cancer who will be undergoing 1st line therapy with gemcitabine or fluorouracil (5-FU) regimens to see how useful it is to look for changes and characteristics in genes (molecules that contain instructions for the development and functioning of the cells) and the genes within the tumour to find characteristics that may be useful in choosing treatments for patients in the future.

The purpose of the study is to establish a repository of human bile as a resource for studies evaluating molecular predictors of biliary cancer risk.

Background Cancer Cachexia (CC) is a multi-factorial process characterized by progressive weight loss, muscle mass and fat tissue wasting, and adversely affecting their quality of life and survival in patients with advanced stage of cancer. Megestrol acetate (MA), which can help maintain body weight in advanced cancer patients, has not been proven to be effective in improving quality of life or lean body mass. Furthermore, its use is often limited due to various adverse event such as Cushing syndrome, adrenal insufficiency, or thromboembolic risk. CC has a complex and multi-factorial pathophysiology, and there is no established standard treatment. Hypothesis CC is irreversible once it occurs and is also difficult to suppress its progression with any single treatment modality. The investigators hypothesized that a multi-modal intervention comprised of anti-inflammation, omega-3-fatty acids, oral nutritional supplement with counselling by nutritionist, physical exercise, psychiatric intervention as well as Bojungikki-tang which mediates immune-modulation and reverse both of chronic inflammation and wasting condition as a complementary and alternative medicine (CAM) could prevent the development of CC or improve the CC in advanced cancer patients during chemotherapy compared to those who received usual supportive.

The aim of this study is to evaluate the usefulness of a newly developed multibending ultra-slim upper endoscope for the successful direct peroral cholangioscopy (POC) without assisting accessory in comparison with conventional ultra-slim endoscope. The investigators expect that multibending endoscope will show more higher successful performance than conventional endoscope.

ERCP with brush cytology has a poor to moderate accuracy in unclear biliary lesions. Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) for cytology may override some of these shortcomings. The current prospective study, performed in a tertiary University center, aims to study the feasibility, the accuracy and the clinical value of combinatory ERCP and EUS in unclear biliary lesions.

The collection of data regarding patient outcomes after surgical intervention creates imperative knowledge to include surgeon performance, cost analysis, base for surgical research and publication, which in turn assist surgeons to improve the standard of care utilizing evidence-based practice.

To investigate the vessel resection and reconstruction in biliary tract cancer.

The key aims of this study include estimation of possible risk associated with a history of gallstones, bacterial infection for the biliary tract, other medical history, diet, use of tobacco and alcohol, obesity, reproductive factors, and family history of cancer. Information will be used to examine risk patterns a) seperately by anatomic subsite; b) among patients with gallbladder cancer vs. controls undergoing cholecystectomy for gallstones; c) among the patients with bile duct cancer vs. Hospital controls without cancer who undergo surgery for removal of bile duct stones. We will also attempt to ascertain reasons for cancer who undergo surgery for removal of bile duct stones. We will also attempt to ascertain reasons for the rising incidence of biliary tract cancers in Shanghai. Serum collected from all subjects will be analyzed for estrogens and other hormones, vitamins C and E, cholesterol, and bacterial antibodies (including salmonella typhi, paratyphi, and escherischia coli). Bile fluid will be cultured for aerobic bacteria, and gallstones analyzed for color, cholesterol, and evidence of bacteria infection. A major challenge in biliary tract cancer research is to determine how cancer risk factors differ from those for gallstones or biliary duct stone disease, since many people have gallstones (or biliary duct stones) but few develop cancer....

The purpose of this study is to explore the precise treatment in hepatobiliary cancer patients and evaluate drug safety, progression free and overall survival. This trial study is based on genetic tests, then therapeutic target drugs are administered according to the genetic test reports. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit from precise treatment which targets particular genetic abnormality. The identifications of these genetic abnormalities may help treat hepatobiliary cancer patients better.
