Abstract
AIM
The aim of this retrospective study is to assess the toxicity and tumor response of stereotactic body radiation therapy (SBRT) protocol for hepatocellular carcinoma (HCC) in our institution.
BACKGROUND
Hepatocellular cancer is one of the leading cancers among men in India. In recent years, SBRT has emerged as a promising tool in the treatment of HCC.
MATERIALS AND METHODS
Ten patients diagnosed as HCC with Barcelona Clinic Liver Cancer Stage B and C, treated with SBRT technique from January 2013 to December 2016, were included in this study. SBRT was delivered using 6 MV photons with volumetric modulated arc therapy. Acute and late toxicities were graded, and tumor response was assessed using response evaluation criteria in solid tumors criteria. Kaplan-Meier curves were generated for progression-free survival (PFS) and overall survival (OS).
RESULTS
The median age was 61.5 (52-69) years. The radiation dose ranged from 35 Gy to 60 Gy. All patients obtained partial response during assessment at 3 months after completion of treatment. The median PFS is 8 months (95% confidence interval [CI] - 5.22-10.77 months). The median OS is 51 months (95% CI - 17.64-65.10 months). The OS at 1 and 2 years is 75% and 57%, respectively.
CONCLUSIONS
SBRT is well tolerated by our patients. The 1- and 2-year OS of 75% and 57% is consistent with other prospective and retrospective SBRT studies from the literature.
