Overall Status
The purpose of this study is to determine whether radioactive stents and common used plastic stents are effective and safety in the treatment of unresectable biliary tract cancer.
Detailed Description
Patients with unresectable biliary tract cancer (intrahepatic or extrahepatic cholangiocarcinoma, or ampullary carcinoma) were enrolled and placed with a stent loaded with radioactive seeds (irradiation stent group) or a conventional plastic stent (traditional stent group). After stent placement, the outcomes were compared in terms of tumor response, progression-free survival, overall survival time, and complications related to the procedures.
