Univariable competing risk regression analysis indicated that donation type, donor BMI, recipient age and sex, underlying liver disease etiology, Child-Pugh score, MELD score, AFP level, tumor count, largest tumor size, macrovascular invasion, tumor differentiation, graft CIT, intraoperative allogeneic blood transfusion, and intraoperative autologous blood transfusion were all potential risk factors for HCC recurrence (P<0.10). The gene discussed is AFP; the disease is hepatocellular carcinoma.
