Key clinical point: The oncological outcome in patients with hepatocellular carcinoma (HCC) who underwent liver transplantation (LT) is strongly affected by the ABO blood group system.
Main finding: Blood group A showed an independent association with increased tumor recurrence risk (adjusted hazard ratio [aHR], 1.574; P = .034) with group A vs non-A recipients having higher 5-year tumor recurrence rates (20.1% vs 13.2%; aHR, 1.66; P = .011) and lower 5-year recurrence-free survival rates (66.8% vs 71.3%; aHR, 1.38; P = .045).
Study details: The data are derived from a multicentric retrospective observational study including 925 adult patients with HCC who underwent LT, of whom 406, 94, 380, and 45 had blood group A, B, O, and AB, respectively.
Disclosures: The authors reported no funding source or conflict of interests.
