Sorafenib in combination with transarterial chemoembolization for hepatocellular carcinoma: a meta-analysis.

OBJECTIVE
This meta-analysis aimed to analyze the efficacy of sorafenib in combination with transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC).


MATERIALS AND METHODS
Electronic data bases were searched for studies (1) enrolled HCC patients undergoing TACE; (2) with sorafenib therapy and control arm of no sorafenib therapy were included for meta-analysis and meta-regression; (3) studies without control arm were included for data review and (4) had time to progression (TTP) and overall survival (OS) or relative outcome of HCC as the endpoint. Meta-analysis and meta-regression were performed according to Cochrane guidelines.


RESULTS
Five studies (3 randomized trials, 1 cohort study and 1 prospective non- randomized controlled trial, totally 899 patients) were eligible for meta-analysis. The hazard ratio (HR) for TTP was 0.75 (95% CI: 0.48-1.03, p = 0.003) with significant heterogeneity (I2 = 82.7%) and for OS was 0.76 (95% CI: 0.47-1.05, p = 0.147) with slight heterogeneity (I2 = 47.9%). However, no covariate was found as independent predictor for better treatment efficacy. Hand-foot skin reaction, alopecia, rash/desquamation, diarrhea, hypertension, fatigue, anorexia, nausea and vomiting were common adverse events.


CONCLUSIONS
TACE combined with sorafenib has potential efficacy for HCC.
