This is a multicentric, open-labal, randomized controlled trial which aims to evaluate the efficacy and safety of Radiation-Emitting Metallic Stents (REMS) combined with Trans-Arterial Infusion (TAI) versus Uncovered Self-Expandable Metallic Stent (SEMS) Combined With Trans-Arterial Infusion (TAI) for Unresectable Hilar Cholangiocarcinoma. The primary hypotheses are that Radiation-Emitting Metallic Stents (REMS) combined with Trans-Arterial Infusion (TAI) is superior to Uncovered Self-Expandable Metallic Stent (SEMS) Combined With Trans-Arterial Infusion (TAI) with respect to Over survival(OS). The primary endpoint is overall survival. The secondary endpoints include quality of life, progression free survival, relief of jaundice, patency, and adverse events.
The purpose of this randomized controlled study is to evaluate the efficacy and safety of the Radiation-Emitting Metallic Stents (REMS) combined with Trans-Arterial Infusion (TAI) for unresectable hilar cholangiocarcinoma.
