BACKGROUND: Sorafenib has become the standard first-line treatment for patients with advanced hepatocellular carcinoma (HCC). This study aimed to assess the efficacy and safety of sorafenib in advanced HCC patients and explore its true value for specific subgroups. DATA SOURCES: A computer-based systematic search from January 2005 to June 2011 with sorafenib and advanced hepatocellular carcinoma as search terms was performed for possible clinical trials. Hazard ratios (HR) and their 95% confidence intervals (CI) for overall survival (OS) and time to progression (TTP), rates of partial response (PR), rates of toxicity effects, and details of subgroup analysis were extracted. Meta-analyses were done using the software Review Manager (version 5.0). RESULTS: Six trials with 1164 patients were included. Based on three randomized controlled trials, the pooled HR (sorafenib/placebo) was 0.66 for OS (95% CI: 0.56-0.78; P<0.00001) and 0.57 for TTP (95% CI: 0.47-0.68; P<0.00001). The pooled odds ratio (OR) for PR was 2.96 (95% CI: 0.96-9.15; P=0.06). For three single-arm trials, the pooled HR was 0.69 for OS (95% CI: 0.56-0.84; P=0.0002) and 0.64 for TTP (95% CI: 0.52-0.78; P<0.00001). The pooled OR for PR in three single-arm trials was 3.56 (95% CI: 1.22-10.39; P=0.02). Subgroup analysis indicated that sorafenib was less effective in patients with extrahepatic spread (with: P=0.13 vs without: P<0.0001), with normal alpha-fetoprotein level (AFP) (P=0.15 vs elevated: P=0.0006), and with elevated level of serum bilirubin (P=0.06 vs normal: P=0.0009). Sorafenib-based therapy significantly increased the risk of grade 3/4 hand-foot skin reaction, diarrhea, fatigue, and rash/desquamation. CONCLUSIONS: Sorafenib-based therapy benefits advanced HCC patients. Meanwhile, sorafenib is less effective for patients with extrahepatic spread, with normal AFP level and with elevated level of bilirubin. (Hepatobiliary Pancreat Dis Int 2012;11:458-466)
