Observation of clinical efficacy of stereotactic body radiotherapy in 28 cases of large hepatocellular carcinoma / 中华放射肿瘤学杂志

ABSTRACT

Objective To observe the survival and side effects of stereotactic body radiotherapy (SBRT) in large hepatocellular carcinoma (HCC) patients.Methods Twenty-eight large HCC patients undergoing SBRT in 302 Military Hospital from November 1,2011 to January 31,2014 were observed.The prescribed dose was 39-61 Gy/3-9f.Among them,20 patients simultaneously received transcatheter arterial embolization.The overall survival (OS),progression-free survival (PFS) and local control (LC) rates were calculated by using Kaplan-Meier method.The influencing factors of OS were analyzed by Cox regression model The influencing factors of radiation-induced liver disease (RILD) were identified by using Logistic regression analysis.Results The 1-,2-,3-and 5-year OS rates were 75％,57％,54％ and 22％,respectively.The 1-,2-,3-and 5-year PFS rates were 59％,47％,36％ and 18％,respectively.The 1-,2-,3-and 5-year LC rates were 92％,86％,86％ and 86％,respectively.Four patients suffered from RILD and none died from RILD.Child-Pugh classification was the influencing factor of OS and RILD.Conclusion It is preliminarily believed that SBRT is an alternative and safe treatment for patients with large HCC.
