Advanced Stage Hepatocellular Carcinoma Successfully Treated with Liver-directed Concurrent Chemoradiotherapy and Sequential Transarterial Radio-embolization.

Abstract

Optimal treatment strategies for patients with advanced hepatocellular carcinoma (HCC) is yet to be determined. Herein, we present a case of advanced HCC with tumor invasion into the right anterior portal vein and right hepatic vein where complete response (CR) was achieved via a multidisciplinary approach. This patient had a 10.5 cm-sized HCC invading segment VI, without extrahepatic spread. Liver function was classified as Child-Pugh class A, and the performance status was good. Transarterial radio-embolization (TARE) was performed 6 weeks after the completion of liver-directed concurrent chemoradiotherapy, and CR was confirmed 3 months post-TARE. Adoptive cell therapies were performed as adjuvant therapy and CR was maintained for over 15 months, until the local recurrence of a 2 cm-sized HCC was found. Therefore, in selected cases with preserved liver function, combination therapies, including LRTs and systemic therapy, can be a useful therapeutic option for advanced HCC.
