Efficiency Evaluation of Photodynamic Therapy With Photofrin® on Unresectable Type III or IV Cholangiocarcinomas
Efficiency Evaluation of Photodynamic Therapy With Photofrin® on Unresectable Type III or IV Cholangiocarcinomas - A Prospective, Multicentric and Randomized Study.
Unresectable type III or IV cholangiocarcinoma has a very bad prognosis; survival median ranges between 6 and 9 months. Survival depends on biliary drainage quality, obtained by plastic or metallic prothesis setting up in one or several hepatic segments. Radiotherapy and/or chemotherapy didn't prove yet their efficiency on survival. In France, gemcitabin is recommended by the French Digestive Oncology Federation in metastatic tumours, in monotherapy or associated with cisplatin or oxaliplatin (Gemox) for patients in good general condition. Photodynamic therapy has shown in 3 prospective studies - one randomized - with small patient series, a significative efficiency on survival and quality of life of treated patients, in comparison with historical series, or patients' groups whose biliary drainage was in most cases unefficient. A new randomized study, including patients whose biliary drainage is efficient and comparing their becoming when they are treated by PDT in addition to current practice, or only by current practice, seems to be justified. The principal objective of this study is to evaluate the efficiency of PDT with Photofrin® on patients with unresectable type III or IV cholangiocarcinoma.
Patients' survival compared between both groups : PDT and non-PDT.
