Stereotactic body radiation therapy following transarterial chemoembolization for Child-Pugh A and B hepatocellular carcinoma.

321 Background: Hepatocellular carcinoma (HCC) incidence continues to increase, but recent improvements in treatment of localized tumors have contributed to modest gains in survival rates. Though transarterial chemoembolization (TACE) and stereotactic body radiation therapy (SBRT) are increasingly used in the management of unresectable HCC, outcomes data regarding the combination of these treatments is limited. Here we report institutional outcomes for patients with Child-Pugh A (CPA) and B HCC treated with TACE followed by SBRT. Methods: We completed an institutional retrospective review of all patients treated with combination TACE and SBRT between 2009 and 2013. After compiling dosimetry, toxicity, and outcomes data for each patient we calculated descriptive statistics for the cohort and determined local control (LC), distant liver control (DLC), progression free survival (PFS), and overall survival (OS) utilizing the Kaplan-Meier method. We also compared these disease-related outcomes between CPA and ...
