Summary
Brief summary (as posted)
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.

- label
- Carbon Ion Radiotherapy
- description
- Participants will receive carbon ion radiotherapy targeting residual or recurrent hepatocellular carcinoma following prior transarterial radioembolization (TARE). Treatment will be delivered using hypofractionated high-linear energy transfer radiation, with dose and fractionation individualized based on tumor size, anatomical location, and organ-at-risk constraints. The intervention aims to provide effective local tumor control while maintaining acceptable safety in patients who have limited subsequent treatment options after TARE.

Primary outcomes (1)
- measure
- Objective Response Rate (ORR)
- timeFrame
- Up to 6 months after completion of carbon ion radiotherapy
- description
- Objective response rate is defined as the proportion of patients achieving complete response (CR) or partial response (PR) according to mRECIST criteria. Tumor response will be assessed through scheduled imaging studies within 6 months after carbon ion radiotherapy.
