AFP and neoplasm: In the multivariate analysis (Table 3), only corona enhancement (hazard ratio [HR]: 2.970; p = 0.013; Figure 3) and irregular tumor margin (HR: 2.377; p = 0.048; Figure 4) were independent predictors in the preoperative prediction model, and preoperative AFP level >200 ng/ml (HR: 2.493; p = 0.044) and corona enhancement (HR: 3.046; p = 0.014) were independent predictors in the postoperative prediction model.
