Active clinical trials for "Klatskin Tumor"

A prospective, open-label, randomised, multicentre, comparative study in two parallel groups comparing an interventional group with liver transplantation preceded by neoadjuvant radio-chemotherapy and a control group receiving conventional liver and bile duct resection. The primary endpoint will be overall survival at 5 years in the intent-to-treat population. The secondary endpoint will be recurrence-free survival at 3 years evaluated by CT-scan and tumoral markers (Carcinoembryonic antigen (CAE) and cancer antigen (CA19.9)) in the intent-to-treat population. The number of subjects necessary is 54 patients (27 x 2): this population will enable the demonstration of a significant difference is 5-year survival rates between the transplanted group and the resected group with a power of 80% and a first-species risk of 5%, under the hypothesis that these survival rates are 70% in the transplanted group and 30% in the resected group.

The purpose of this study is to determine the effect of normal temperature and 37℃ non-ionic contrast agent acting on ERCP-related cholangeitis after endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of hilar cholangiocarcinoma.

This study is going to test the ability to successfully obtain results from certain personalized tests for patients with biliary tract cancers that are able to be surgically removed. Through surveys, this study will also evaluate the usefulness of these tests to medical oncologists as they make decisions on what standard or experimental treatments might benefit the patient's enrolled in the study. The study is observational and does not require any change in the standard approach to treating biliary tract cancer. Results of the personalized tests will be provided to the treating medical oncologist and the medical oncologist can choose to whether or not to change management based on these results. These personalized tests include reading of the cancer DNA, testing whether a panel of drugs can kill a patient's cancer cells in a test tube, and testing for small amounts of cancer DNA in the blood as a way to check for the presence of leftover cancer in the body after it is removed surgically. This study will also give extra pieces of cancer, that would otherwise be discarded, from surgery for laboratory research into how biliary tract cancers respond to drugs and the body's immune system. The investigators hypothesize that the drug screen test will, in some cases, be useful to the medical oncologist and may lead to the use of cancer drugs that would not otherwise have been chosen based on standard guidelines or based on cancer DNA testing. The investigators hypothesize that the test tube drug screening method will correlate with how the cancer responds to the drugs in real life for those patients that end up receiving a drug that was included in the drug screen panel. The investigators hypothesize that monitoring of cancer DNA in the blood stream will help us predict which patients are most likely to have their cancer return after surgery. The investigators also hypothesize that in many cases the appearance of cancer DNA in the blood stream will happen weeks to months prior to the cancer showing up on usual body imaging or other lab tests. Finally, the investigators hypothesize that, for patients undergoing medical treatment for their cancer, trends in the amount of cancer DNA in the blood stream will correlate with the effectiveness of treatment.

A prospective multicentre study which includes patients ≤ 70 years-old diagnosed of unresectable hilar cholangiocarcinoma (hCCA) ≤3cm in radial diameter, without evidence of lymph node or distant metastases. Liver transplantation preceded by neoadjuvant radio-chemotherapy will be performed in this selected group. The primary endpoint will be overall survival at 1, 3, and 5 years post-transplant. The secondary endpoints will be: 1) recurrence free survival at 1, 3 and 5 years post-transplant; 2) intention-to-treat survival of overall patients included in the study at 1,3 and 5 year; 3) the rate of patients included in the study who are finally transplanted.

The goal of this observational cohort study is to assess the yield of preoperative endoscopic ultrasound focussed on lymph nodes in patients with presumed resectable perihilar (pCCA), intrahepatic (iCCA) or mid-common bile duct (CBD) cholangiocarcinoma. The main questions it aims to answer is: The number of patients precluded from surgical work-up due to positive regional or extraregional lymph nodes identified by endoscopic ultrasound guided tissue acquisition Characteristics during endoscopic ultrasound of lymph nodes associated with malignancy

This is a prospective, observational diagnostic study aiming to assess multiparametric MRI-based clinico-radiomics for identifying lymph node metastasis status in hilar cholangiocarcinoma.

Photodynamic therapy (PDT) is a combination of a drug, porfimer sodium (Photofrin), which is activated by a light from a laser that emits no heat. This technique works to allow the medical doctor to specifically target and destroy abnormal or cancer cells while limiting damage to surrounding healthy tissue. The activation of the drug is done by lighting the abnormal areas using a fiber optic device (very fine fiber like a fishing line that permits light transmission) inserted into a flexible tube with a light called cholangioscope for the bile duct. The light will activate the porfimer sodium concentrated in the abnormal tissue, leading to its destruction. This research study will evaluate the efficacy and safety of PDT with porfimer sodium administered with Standard Medical Care (SMC) compared to SMC alone on the overall survival time of patients with non-operable advanced cholangiocarcinoma, a rare cancer of the bile ducts. It will involve 200 patients across North America and Europe. Other countries may participate if needed. Participation will last at least 18 months.

The purpose of this study is to test the safety of giving external beam radiation, followed by a Cyberknife radiosurgery boost at different dose levels, together with a chemotherapy drug called capecitabine. The dose of Cyberknife radiosurgery boost will be made higher slowly in this protocol. Patients with hilar cholangiocarcinoma (Klatskin tumor), which is not amenable for surgical removal, are eligible. The hypothesis is that highly focused high dose radiation delivered using Cyberknife in conjunction with traditional radiation and chemotherapy can improve outcome in this patient population.

Primary objective: To investigate the objective response rate in patients with ROS1 or ALK over-expressed locally advanced, or metastatic intrahepatic or hilar cholangiocarcinoma receiving LDK378 Secondary objectives:The progression-free survival ,The disease control rate ,The overall survival ,The toxicity profiles , The correlation between clinical outcomes and the potential predictive biomarker for tumor response

This is a multi-center, randomized, controlled, open-label, phase IIa clinical study.The study will observe the efficacy and safety of Deuteporfin photodynamic therapy in addition to stenting compared to stenting alone in patients with unresectable advanced Perihilar Cholangiocarcinoma.
