The significant independent predictors of intrahepatic recurrence-free survival were microvascular invasion (P <0.001), tumor number (P = 0.039), albumin levels (P = 0.004), and AST levels (P = 0.025) for men; for women, the predictors were microvascular invasion (P = 0.002) and AST levels (P < 0.001) (Additional file 2: Table S2). The gene discussed is ALB; the disease is neoplasm.
