Abstract:
Objective The aim of this study was to compare the short-term and long-term prognostic significance of dif-ferent systemic inflammatory scores in patients with gastric cancer:neutrophil lymphocyte ratio(NLR) and platelet lymphocyte ratio ( PLR). Methods The clinical data of 240 patients with gastric cancer who underwent radical surgery were retrospectively analyzed. The relationship between NLR,PLR,glasgow prognostic score( GPS) and clinicopathological characteristics and perioperative compli-cations were compared. Survival analysis was performed using Kaplan-Meier survival analysis. The Log-rank methods were used to test the difference significance,and the multivariate analysis was performed using the Cox regression risk model. Results Patients in the high NLR and PLR groups were older,had a high GPS,deep tumor infiltration,more lymph node metastasis,and a late TNM stage (P<0. 05). The rate of positive margin in the high NLR group was higher(P<0. 05). Patients in the high NLR and PLR groups re-quired significantly higher transfusion rates than those in the low NLR and PLR groups(P<0. 05),and the high NLR group had more postoperative complications(P<0. 05). Univariate analysis showed that age,GPS,tumor location,tumor infiltration depth,lymph node metastasis status,TNM stage,vascular tumor thrombus,nerve infiltration,NLR and PLR were associated with postoperative survival of gastric cancer patients(P<0. 05). The overall survival(OS)in high NLR and high PLR groups was lower than that of low NLR and low PLR groups(P=0. 018 and P<0. 001). Cox regression analysis showed GPS and lymph node metastasis were independent prog-nostic factors of OS(P<0. 001 and P=0. 002). Conclusion Preoperative systemic inflammatory scores NLR and PLR are prognos-tic factors affecting the preoperative clinical outcomes of gastric cancer. It is recommended to be used in combination with other prog-nostic indicators for routine use in the prognosis of patients undergoing radical gastrectomy.
