A Single-arm Phase II Clinical Study Investigating the Safety and Efficacy of Carbon Ion Radiotherapy in Patients With Hepatocellular Carcinoma Previously Treated With Transarterial Radioembolization (TARE)
Sponsor: Yonsei University
Summary
This is a prospective, single-arm Phase II study designed to evaluate the safety and efficacy of carbon ion radiotherapy in patients with hepatocellular carcinoma (HCC) who demonstrate residual or recurrent disease after prior transarterial radioembolization (TARE). Carbon ion radiotherapy delivers highly conformal, high-linear energy transfer radiation, enabling dose escalation to hepatic tumors while minimizing exposure to surrounding normal tissues. Eligible patients will receive carbon ion radiotherapy to target lesions, and clinical outcomes including objective response rate, progression-free survival, overall survival, and treatment-related toxicity will be systematically assessed. The study aims to determine whether carbon ion radiotherapy can provide effective local tumor control and acceptable safety in this population, thereby establishing evidence to guide its therapeutic role following TARE.

Carbon Ion Radiotherapy
Carbon ion radiotherapy will be delivered to residual or recurrent hepatocellular carcinoma in patients previously treated with transarterial radioembolization (TARE). Treatment will be administered using hypofractionated high-linear energy transfer radiation, with dose and fractionation individualized based on tumor size, tumor location, and organ-at-risk constraints. The aim of the intervention is to achieve enhanced local tumor control while minimizing toxicity to surrounding normal tissues
