Disease-free survival of each independent risk factor. The median disease-free survival (DFS) was 8.4 months in patients with CA19-9 ≥ 529 U/mL, compared to 27.1 months in patients with CA19-9 < 529 U/mL, with a significant difference between the groups (P = 0.0008) (a). The median DFS was 16.1 months in patients with histological grades G2-G4, compared to 51.5 months in patients with G1, with no significant difference (P = 0.2197) (b)
