RFA Combined With Chemotherapy for Unresectable Cholangiocarcinoma

Extrahepatic cholangiocarcinoma is a malignant tumor that is highly malignant and difficult to diagnose and treat early. Endobiliary radiofrequency ablation (RFA) has been reported to be a beneficial treatment option for palliation of malignant biliary strictures. Within the bile duct, RFA appears to be safe and may result in decreased tumor ingrowth. To date, little is known about the role of the addition of systemic chemotherapy to RFA for cholangiocarcinoma. The aim of this study is to compare the efficacy and safety of RAF combined with Gemcitabine and S-1 in patients with unresectable cholangiocarcinoma.
