Statins have been reported to prevent the development of hepatocellular carcinoma (HCC). We examined whether statin therapy is associated with decreased HCC recurrence in patients who underwent liver transplantation for HCC. Three hundred forty-seven patients ≥ 20 years old who underwent liver transplantation for HCC from 2006 to 2016 were enrolled in this study. Statin therapy was defined as the administration of statins for more than 30 days after liver transplantation. One hundred twelve (32.3%) patients treated with statins over 30 days were defined as the statin group, and the remaining 235 (67.7%) were defined as the non-statin group. Several risk factors reported to be associated with HCC recurrence, such as proportion of underlying liver disease, above Milan criteria, differentiation of HCC, vascular invasion, and preoperative alpha-fetoprotein level were not different between the two groups. Time-dependent Cox regression analysis showed that statin treatment was associated with significantly lower recurrence risk of HCC after adjusting for other risk factors (hazard ratio = 0.32, 95% CI = 0.11-0.89).
