摘      要：AIM: to compare the recurrence-free survival (RFS) and overall survival (OS) of hepatitis B virus (HBV)-positive hepatocellular carcinoma (HCC) after living donor liver transplantation (LDLT) and deceased donor liver transplantation (DDLT). METHODS: We retrospectively collected clinical data from 408 liver cancer patients from February 1999 to September 2012. We used the chi-squared test or Fisher s exact test to analyze the characteristics of LDLT and DDLT. Kaplan-Meier analysis was used to compare the RFS and OS in HCC. RESULTS: Three hundred sixty HBV-positive patients (276 DDLT and 84 LDLT) were included in this study. The mean follow-up time was 27.1 mo (range 1.1-130.8 mo). One hundred eighty-five (51.2%) patients died during follow-up. The 1-, 3-, and 5-year RFS rates for LDLT were 85.2%, 55.7%, and 52.9%, respectively; for DDLT, the RFS rates were 73.2%, 49.1%, and 45.3% (P = 0.115). The OS rates were similar between the LDLT and DDLT recipients, with 1-, 3-, and 5-year survival rates of 81.8%, 49.5%, and 43.0% vs 69.5%, 43.0%, and 38.3%, respectively (P = 0.30). The outcomes of HCC according to the Milan criteria after LDLT and DDLT were not significantly different (for LDLT: 1-, 3-, and 5-year RFS: 94.7%, 78.7%, and 78.7% vs 89.2%, 77.5%, and 74.5%, P = 0.50; for DDLT: 86.1%, 68.8%, and 68.8% vs 80.5%, 62.2%, and 59.8% P = 0.53). CONCLUSION: The outcomes of LDLT for HCC are not worse compared to the outcomes of DDLT. LDLT does not increase tumor recurrence of HCC compared to DDLT. (C) 2014 Baishideng Publishing Group Inc.
