[Efficacy and safety of sorafenib in the prevention and treatment of hepatocellular carcinoma recurrences after liver transplantation].

OBJECTIVE:To evaluate the efficacy and safety of sorafenib in the prevention and treatment of hepatocellular carcinoma (HCC) relapse after liver transplantation. METHODS:A retrospective cohort study was performed to assess the efficacy and safety of sorafenib for HCC. Forty-four patients who underwent liver transplant for HCC beyond Milan criteria form July 2007 to May 2010 were included study group (sorafenib, n = 22) and control group (without sorafenib, n = 22). The primary endpoints of the study were disease-free survival (DFS), overall survival (OS). Secondary outcomes included the rates of acute rejection and graft survival. RESULTS:The clinical data of 44 patients were completely collected. There were significantly differences between sorafenib group and control group in 1-year DFS (81.8% (n = 18) vs 63.6% (n = 14), P < 0.05) and OS (90.9% (n = 20) vs 72.7% (n = 16), P < 0.05) respectively. The acute rejection rates in Sorafenib were 13.6% (3/22), compared with 18.2% (4/22) in control group (P = 0.524) and 1-year graft survival in Sorafenib group were 86.4% (19/22), compared with 72.7% (16/22) in control group (P = 0.086). The overall incidence of treatment-related adverse events was 68.1% (n = 15) in sorafenib group and 31.8% (n = 7) in the control group (P < 0.01). Adverse events that were reported for patients receiving sorafenib were predominantly grade 1 or 2 in severity including diarrhea (45.5%, n = 10), liver dysfunction (40.9%, n = 9), hand-foot skin reaction (31.8%, n = 7) and pains of head and four limbs (22.7%, n = 5). Two patients with grade 3 adverse events in study group were stopped continuing to use the sorafenib. Three patients with the dose of 400 mg twice daily and 17 patients with the dose reduction of sorafenib continued to the study endpoint. CONCLUSION:Patients with HCC undergoing liver transplantation could get the benefits of Sorafenib in reducing the incidence of tumor recurrence and extending disease-free and overall survival time.
