In univariate and multivariate Cox analysis, risk score, TNM stages and vascular invasion were evaluated as continuous variables, and AFP, cirrhosis, gender, age and race were evaluated as category variables. Age category and AFP category were defined by 50 and 20 ng/ml as cut-off value, respectively
