Liver Resection Versus Radio-chemotherapy-Transplantation for Hilar Cholangiocarcinoma

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.
