AFP and neoplasm: On the univariate analysis, the following factors were associated with unfavorable DFS: serum AFP levels (hazard ratio [HR], 1.959; 95% CI, 1.439–2.666; P < 0.001), tumor number (HR, 1.745; 95% CI, 1.157–2.632; P < 0.001), tumor size (HR, 3.303; 95% CI, 2.443–4.466; P < 0.001), capsule (HR, 1.598; 95% CI, 1.192–2.144; P = 0.002), microvascular invasion (MVI) (HR, 2.583; 95% CI, 1.877–3.552; P < 0.001), differentiation (HR, 1.594; 95% CI, 1.129–2.249; P = 0.002), AJCC stage (HR, 3.957; 95% CI, 2.599–6.024; P < 0.001), and Milan criteria (HR, 2.420; 95% CI, 1.799–3.255; P < 0.001) (Table 2).
