Active clinical trials for "Klatskin Tumor"

Endoscopic retrograde cholangio-pancreatography (ERCP) is advanced endoscopic technique that allows minimally invasive management of biliary and pancreatic disorders. However, the incidence of infectious complication of ERCP is considerable. Transient blood stream infection after ERCP has been reported in a high ratio, up to 27% and post-ERCP infection accounts for about 10% of the major complications associated with mortality. Although prophylactic use of antibiotics is generally not recommend in all cases, debates about the prophylactic use of antibiotics continues and prophylactic use of antibiotics is recommend in case of ERCP that incomplete biliary drainage is expected. In this study, researchers will use prophylactic antibiotics in patients with biliary obstruction who have high-risk of post-ERCP bacteremia. Antibiotics regimen is selected based on the data of our institution, and administered to patients before ERCP procedure.

Cholangiocarcinoma is an epithelial cell malignancy arising from varying locations within the biliary tree and is difficult to diagnose due to the often-silent clinical nature. The best chance of long-term survival and potential cure is surgical resection with negative surgical margins, but many patients are unresectable due to locally advanced or metastatic disease at diagnosis. Because cholangiocarcinoma is difficult to diagnose at an early stage and extends diffusely, most patients have unresectable disease at clinical presentation, and prognosis is very poor (5-year survival is 0-40% even in resected cases) There is a need for better visualization of tumor tissue, lymph nodes and resection margins during surgery for perihilar cholangiocarcinoma (PHCC). Optical molecular imaging of PHCC associated biomarkers is a promising technique to accommodate this need. The biomarkers Vascular Endothelial Growth Factor (VEGF-A), Epidermal Growth Factor Receptor (EGFR) and c-MET are all overexpressed in PHCC versus normal tissue and are proven to be valid targets for molecular imaging. Currently, tracers that target these biomarkers are available for use in clinical studies. In previous studies with other tumor types, the investigators tested the tracer bevacizumab-IRDye800CW for the biomarker VEGF-A with very promising results. Since all markers show roughly similar expression in ex vivo studies, the initial study will be performed with bevacizumab-IRDye800CW as the investigators have the most experience with this tracer. The investigators hypothesize that the tracer bevacizumab-IRDye 800CW accumulates in PHCC tissue, enabling visualization using a NIR intraoperative camera system and ex vivo NIR endoscopy. In this pilot study, the investigators will determine if it is possible to detect PHCC intraoperatively and by ex vivo NIR endoscopy using bevacizumab 800CW, and which tracer dose gives the best target-to-background ratio. The most optimal tracer dose will be selected for a future phase II trial.

Surgery for perihilar cholangiocarcinoma offers the only possibility of long-term survival, but remains a formidable undertaking. Traditionally, 90 day post-operative complications and death have been used to define operative risk. However, there is concern that this metric may not accurately capture long-term morbidity after such complex surgery. This is a retrospective review of a prospective database of patients undergoing surgery for perihilar cholangiocarcinoma at a Western centre between 2009-2017.

Brief Summary: This is a multicentric, retrospective, real-world study to investigate the surgical outcomes of minimally invasive surgery compared with open surgery for Perihilar Cholangiocarcinoma (PHC), with the perioperative characteristics and long-term overall survival being compared. We aimed to find out whether the minimally invasive surgery is safe or feasible for PHC. And we also want to find out patients with what kind of characteristic can be benefit from the minimally invasive surgery compared with the open approach.

The aim of this study is to reduce the length of stay after liver surgery by taking account of objective quantitative clinical variables, subjective qualitative clinical variables and non clinical variables.

Curative treatment of peri hilar cholangiocarcinomas is R0 surgery and require major hepatectomy with biliary tract resection. These complexe procedures can lead to high morbidity and mortality. A severe alteration of nutritional status before the surgery might be a poor prognosis for survival.

The purpose of this study is to compare the quality of life in patients with unresectable hilar cholangiocarcinoma on palliative metallic stent versus plastic Stent.

To evaluate the feasibility and performance of coregistered 18F-FDG-PET/MRI in the staging of potentially respectable hilar cholangiocarcinoma.

This is an expanded access program (EAP) for eligible participants who do not qualify for participation in, or who are otherwise unable to access, the ongoing clinical trial ABC-108. This program is designed to provide access to ABC294640 (Yeliva ®) for treatment of cholangiocarcinoma (CCA) prior to approval by the local regulatory agency. Availability will depend on territory eligibility. Participating sites will be added as they apply for and are approved for the EAP. An oncologist must decide whether the potential benefit outweighs the risk of receiving an investigational therapy based on the individual patient's medical history and program eligibility criteria.

This retrospective monocentric study aims at comparing multimodality endoscopic biliary drainage versus percutaneous radiologic biliary drainage in case of perihilar malignant obstruction. Data from patients admitted in the Nancy University Hospital, France, between january 2016 and march 2022 with jaundice and perihilar obstruction will be retrospectively collected.
