Endovascular implantation of I-125 seed combined with transcatheter arterial chemoembolization for unresectable hepatocellular carcinoma

摘要

Aim: The purpose of this study was to evaluate the efficacy and safety of the endovascular implantation of I-125 seed under ultrasound and x-ray guidance combined with transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT). Patients & methods: The study included 134 pathologically proven or clinically confirmed primary HCC patients with PVTT in our hospital from January 2013 to June 2015. Results & conclusion: Compared with the TACE treatment alone, the combination therapy of I-125 seed implantation with TACE significantly prolonged the median survival time and improved the 6-, 12- and 18-month survival rates for HCC patients with PVTT. In addition, the type III PVTT and tumor size were independent predictors for poor prognosis of HCC patients with PVTT.
