Independent factors that were associated with a 3‐year survival time as shown by multivariate analysis (logistic regression model) (Table 4) included a lower AST (OR 1.944, P = 0.033), lower AFP (OR 3.404, P < 0.001), smaller tumor size (OR 2.417, P = 0.005), solitary tumor (OR 2.131, P = 0.014), and the absence of vascular invasion (OR 2.271, P = 0.021). This evidence concerns the gene AFP and neoplasm.
