TACE Plus Atezolizumab/Bevacizumab and I-125 Seeds Brachytherapy for HCC With Branch PVTT

Summary

The present study aimed to assess the effectiveness of the combination treatment of Atezolizumab/Bevacizumab, transcatheter arterial chemoembolization (TACE) and I-125 Seeds Brachytherapy (TACE-AB-I) in patients with advanced hepatocellular carcinoma (HCC) and portal vein tumor thrombosis (PVTT). The investigators confirmed that the combination therapy yielded better survival data than the combined administration of Atezolizumab/Bevacizumab and TACE (TACE-AB) in patients with advanced HCC and Type I/II PVTT (Based on Cheng's PVTT classification).
