DFS and OS of patients with gastric cancer receiving postoperative chemotherapy in the NNCT group.
Notes: Patients receiving postoperative chemotherapy form the C group and those not receiving postoperative chemotherapy form the D group. (A) Kaplan–Meier analysis of DFS for the SII of patients with gastric cancer receiving postoperative chemotherapy. (B) Kaplan–Meier analysis of OS for the SII of patients with gastric cancer receiving postoperative chemotherapy. (C) Kaplan–Meier analysis of DFS for low SII of patients with gastric cancer receiving postoperative chemotherapy. (D) Kaplan–Meier analysis of OS for low SII of patients with gastric cancer receiving postoperative chemotherapy. (E) Kaplan–Meier analysis of DFS for high SII of patients with gastric cancer receiving postoperative chemotherapy. (F) Kaplan–Meier analysis of OS for high SII of patients with gastric cancer receiving postoperative chemotherapy. SII is a novel systemic immune–inflammation index (SII=N×P/L), which is based on neutrophil (N), platelet (P) and lymphocyte (L) counts.
Abbreviations: DFS, disease-free survival; NNCT, non-neoadjuvant chemotherapy; OS, overall survival.
