Aim: Hepatocellular carcinoma (HCC) is primarily treated with hepatic resection and/or locoregional therapy. When HCC recurs and further treatment is no longer possible owing to poor liver function, liver transplantation (LT) or living-donor LT (LDLT) is considered. The aim of this study was to clarify risk factors for tumor recurrence after LDLT in patients with recurrent HCC. Methods: The study comprised 104 patients who had undergone LDLT because of end-stage liver disease with recurrent HCC. The recurrence-free survival rates after the LDLT were calculated. Risk factors for tumor recurrence were identified. Results: The 1-, 3- and 5-year recurrence-free survival rates were 89.6%, 80.3% and 78.4%, respectively. By univariate analysis, the factors affecting recurrence-free survival were the sum of the largest tumor size and number of tumors of 8 or more (P<0.0001), des-γ-carboxy prothrombin of more than 300mAU/mL (P = 0.0001), and a neutrophil-to-lymphocyte ratio (NLR) of 4 or more (P = 0.0002), α-fetoprotein of more than 400ng/mL (P = 0.0001) and bilobar tumor distribution (P = 0.046). A multivariate analysis identified independent risk factors for post-LDLT tumor recurrence including the sum of tumor size and number of tumors of 8 or more (P = 0.0004) and an NLR of 4 or more (P = 0.01). The 1- and 3- year recurrence-free survival rates in the recipients who had both risk factors were 30.0% and 15.0%, respectively. Conclusion: LDLT should not be performed for patients who have both independent risk factors after any treatments for HCC.
