Background: The prognosis of hepatocellular carcinoma remains poor even after curative resection and it has no effective adjuvant therapy. Aim: This meta-analysis aimed to assess efficacy of sorafenib as adjuvant therapy for patients with hepatocellular carcinoma after resection. Materials and methods: A systematic search was conducted of Medline, Embase, Web of Science, Cochrane Library, Chinese Wanfang database, Chinese biological and medical database, China National Knowledge and the Internet, data from 5 studies that included 296 participants were analyzed. The primary outcome was overall survival. Secondary outcomes included recurrence rate and mortality rate. Results: In the comparison of sorafenib versus control, no significant difference in overall survival (hazard ratio 1.39, 95% confidence interval [CI] 0.71-2.74, P = 0.34) or recurrence rate [risk ratio (RR) 0.81, 95% CI; 0.65-1.01, P = 0.06) was found. For mortality rate, subgroup analysis was conducted according to study type, only in subgroup 2, the RR was significantly reduced (0.66, 95% CI; 0.51-0.87, P = 0.003) in studies. Conclusions: In this meta-analysis, sorafenib achieves no significant benefit in any of the endpoints except a lower mortality rate in subgroup analysis, indicating that there is no convincing evidence of sorafenib as an effective adjuvant therapy in patients with hepatocellular carcinoma after resection.

Since HCC shows resistance to chemotherapy and radiotherapy, sorafenib, as the only standard oral multikinase inhibitor approved by the U.S. Food and Drug Administration and European Medicines Agency for HCC, has been demonstrated to benefit overall survival for HCC [8]. Also sorafenib has been proven to improve prognosis of advanced renal-cell carcinoma [9] and advanced thyroid cancer [10]. Furthermore, experiments in vivo show that sorafenib inhibits tumor growth and prevents metastatic recurrence after resection of HCC in nude mice [11]. However, recent opinions that sorafenib as adjuvant therapy could benefit patients with HCC after resection are still controversial [12–16].
