BACKGROUND: Living-donor liver transplantation (LDLT) is becoming an important tool in hepatocellular carcinoma (HCC) treatment. However, the oncologic outcome between LDLT and deceased-donor LT (DDLT) for HCC remains controversial. This study aims to compare the HCC recurrence rates after LDLT versus DDLT. METHODS: Two hundred sixteen patients (166 LDLTs and 50 DDLTs) who underwent LT for HCC within University of California-San Francisco criteria were retrospectively reviewed. LDLT patients were divided into two groups: small living-donor graft (LDG; graft-to-recipient body weight ratio <1.0, n=59) and nonsmall LDG (graft-to-recipient body weight ratio ≥1.0, n=107). Patients were further stratified into low- and high-risk settings by the number of risk factors for recurrence. RESULTS: The recurrence-free survival was lower in LDLT compared with DDLT (88.6% and 80.7% vs. 96.0% and 94.0% at 1 and 5 years; P=0.045). There was no significant difference between two groups regarding the majority of clinical and tumor characteristics, with the exception of a higher proportion of microvascular invasion presence in LDLT. After the adjustment for microvascular invasion, LDLT was identified as an independent risk factor for recurrence. Moreover, recurrence-free survival between small and nonsmall LDG was not statistically significant. In low-risk setting (≤1 risk factor), LDLT showed comparable outcome with DDLT. However, the risk of recurrence was higher in LDLT than DDLT in high-risk patients. CONCLUSION: In conclusion, LDLT showed poorer outcome than DDLT. This should be considered to select optimal strategy for HCC.
