Follow-up was until 2014 or patient death. Two groups were defined in the experiment: The experimental group, treated with sorafenib plus TACE, and the control group, treated with standard TACE alone.RESULTS The Kaplan-Meier survival analysis showed that the median overall survival(m OS) of the experimental group was 35.2 mo, while that of the control group was 22.0 mo(P < 0.05). Sorafenib plus TACE showed higher incidence rates of rash, hand-foot syndrome(HFS), and hypertension(P < 0.05) than TACE treatment alone.CONCLUSION Sorafenib plus TACE treatment for BCLC-B HCC significantly prolonged the m OS of patients compared to TACE treatment alone. The most common toxicities with sorafenib were rash(31.6%), HFS(39.5%) and hypertension(31.6%), but there were no intolerable adverse events. The Cox multivariate analysis showed that the survival of patients with BCLC-B HCC depended on the Child-Pugh classification, tumor diameter, and treatment with sorafenib plus TACE compared to TACE alone.展开更多
