AbstractSeveral studies have reported higher rates of recurrent hepatocellular carcinoma (HCC) after living donor liver transplantation (LDLT) versus deceased donor liver transplantation (DDLT). It is unclear whether this difference is due to a specific biological effect unique to the LDLT procedure or to other factors such as patient selection. We compared the overall survival (OS) rates and the rates of HCC recurrence after LDLT and DDLT at our center. Between January 1996 and September 2009, 345 patients with HCC were identified: 287 (83%) had DDLT and 58 (17%) had LDLT. The OS rates were calculated with the Kaplan-Meier method, whereas competing risks methods were used to determine the HCC recurrence rates. The LDLT and DDLT groups were similar with respect to most clinical parameters, but they had different median waiting times (3.1 versus 5.3 months, P = 0.003) and median follow-up times (30 versus 38.1 months, P = 0.02). The type of transplant did not affect any of the measured cancer outcomes. The OS rates at 1, 3, and 5 years were equivalent: 91.3%, 75.2%, and 75.2%, respectively, for the LDLT group and 90.5%, 79.7%, and 74.6%, respectively, for DDLT (P = 0.62). The 1-, 3-, and 5-year HCC recurrence rates were also similar: 8.8%, 10.7%, and 15.4%, respectively, for the LDLT group and 7.5%, 14.8%, and 17.0%, respectively, for the DDLT group (P = 0.54). A regression analysis identified microvascular invasion (but not the graft type) as a predictor of HCC recurrence. In conclusion, in well-matched cohorts of LDLT and DDLT recipients, LDLT and DDLT provide similarly low recurrence rates and high survival rates for the treatment of HCC.Copyright © 2012 American Association for the Study of Liver Diseases.
