The aim of this study was to examine the impact of postoperative NLR on prediction for postoperative recurrence of gastric cancer. Patients and Methods: A retrospective analysis was performed on data from 170 patients with Stage II/III gastric cancer who underwent surgery followed by adjuvant chemotherapy using S-1 between 2006 and 2015. Postoperative NLR was calculated every 6 months and the data at the time of recurrence or last survival were used for analysis. Results: Postoperative NLR was associated with Prognostic nutritional index (PNI) and modified Glasgow Prognostic Score (mGPS). In multivariate analysis, we found that elevated CA19-9, CEA and NLR were independent predictive markers. The patients with low values of both NLR and CEA after surgery had the most favorable prognosis. Conclusion: The postoperative NLR might be one of the surrogate markers for recurrence after curative surgery for patients with Stage II/III gastric cancer. %U https://ar.iiarjournals.org/content/anticanres/38/6/3745.full.pdf
