BackgroudInflammation can promote tumor growth, invasion, angiogenesis and even metastasis. Inflammatory markers have prognostic value in some malignancies. The aim of the present study was to examine whether neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) served as sensitive serum markers for predicting lymph node metastasis and prognostic factors in gastric cancer (GC) patients.Methods904 consecutive patients who underwent radical total or subtotal gastrectomy between 2010 and 2011, were included in this study. The clinical utility of the NLR and PLR was evaluated by receiver operating characteristic (ROC) curves,Kaplan-Meier curves and Cox regression analyses were used to calculate the overall survival (OS) characteristics.ResultsWe determined the cutoff values of NLR and PLR was 2.0 and 160 respectively according to the ROC curve. Both the NLR and PLR were significantly associated with LN (lymph node) metastasis, and high NLR and PLR groups were significantly associated with poor overall survival. Additionally, NLR and TNM stage were independent prognostic factors for overall survival, however, PLR had limited value.ConclusionsNLR and PLR levels may be valuable indexes for lymph node metastasis. Although both the PLR and NLR may have prognostic value of gastric cancer patients, NLR is better to predict overall survival than PLR.Copyright © 2018 IJS Publishing Group Ltd.
