Objective To analyze the role of preoperative peripheral blood inflammatory parameters and postoperative lymph-node ratio (LNR) in the prognosis of gastric cancer patients treated with chemotherapy.
Methods The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune inflammatory response index (SII), lymphocyte-to-monocyte ratio (LMR), Onodera prognostic nutritional index (OPNI), and LNR of 108 patients with gastric cancer were classified into high and low groups to analyze their prognostic value on the overall survival (OS) of gastric cancer patients treated with chemotherapy. The independent prognostic indicators were plotted in columns to predict the survival rate of gastric cancer patients.
Results NLR was statistically significant in the prognostic assessment of gastric cancer patients treated with chemotherapy (P < 0.001). Moreover, the high PLR group, high SII group, high LNR group, N3 stage, TNM (Ⅲ-Ⅳ) stage, nerve invasion, and carcinoembryonic antigen (CEA) were independent risk factors for the prognosis of gastric cancer (all P < 0.05). These findings indicated that in predicting the prognosis of gastric cancer, the combination of LNR, PLR, and SII (AUC=0.875) was better than that of LNR, PLR, and SII alone or in pairwise combination.
Conclusion Elevated NLR, LNR, PLR, and SII are associated with significantly reduced survival of patients. LNR, PLR, and SII could be used as independent risk factors for the prognosis of gastric cancer patients treated with chemotherapy, and their combination can predict the survival of gastric cancer patients.
