Survival curve of each independent risk factor. The median overall survival (OS) was 23.1 months in patients with CA19-9 ≥ 529 U/mL, compared to 55.9 months in patients with CA19-9 < 529 U/mL, with a significant difference between the groups (P = 0.0038) (a). The median OS was 37.5 months in patients with histological grades G2–G4, compared to 64.6 months in patients with G1, with no significant difference (P = 0.0648) (b)
