AFP and neoplasm: Multivariate Cox regression analyses revealed that covariates significantly associated with PFS included ≥4 (vs. <4) tumors (adjusted HR, 2.34; p = 0.001), tumor size >10 cm (vs. ≤10 cm) (adjusted HR, 1.75; p < 0.001), and AFP concentration ≥400 ng/mL (vs. <400 ng/mL) (adjusted HR, 1.61; p = 0.001) (Table 2).
