Abstract
Objective: To evaluate the initial result and toxicity of stereotactic body radiotherapy (SBRT) for hepatocellular carcinoma (HCC) patients with portal vein thrombosis. Subject and method: A prospective study on 30 HCC patients with portal vein thrombosis were treated by SBRT, follow-up between July, 2018 to April, 2021. Evaluation criteria were ojective response rate (ORR), overall survival (OS), toxicity and cause of death. Result: Thrombosis location: Vp4 + Vp3 (53.3%). Mean radiation dose was 35.7 ± 3.1Gy/3 - 5 fraction. The ORR after 1 month, 3 months were 80%, 73.3%, respectively. The median OS was 14.5 months. The OS rate after 6 month, 1-year were 96.7%, 63.3%. Most of toxicities were grade 1-2 including fatigue, nausea, abdominal pain. Conclusion: SBRT is a safe and effective treatment option for PVT in HCC patients with minor toxicity.
