Living donor liver transplantation does not increase tumor recurrence of hepatocellular carcinoma compared to deceased donor transplantation

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.
