AB  - Background/Aim: The aim of the present study was to evaluate the clinical impact of the pretreatment lymphocyte-to-monocyte ratio (LMR) on both short- and long-term oncological outcomes in patients with resectable gastric cancer (GC). Patients and Methods: The patients were chosen based on our medical records from consecutive cases of curative resection for GC performed at Yokohama City University from 2005 to 2020. The LMR was calculated as the lymphocyte count divided by the monocyte count measured before surgery. Results: The three- and five-year overall survival (OS) rates were 63.1% and 57.4%, respectively, in the low-LMR subgroup and 86.4% and 77.5%, respectively, in the high-LMR subgroup. According to multivariate analysis, the LMR was an independent prognostic factor for OS [hazard ratio (HR)=1.926, 95% confidence interval (CI)=1.143-3.245, p=0.014]. In addition, the three- and five-year RFS rates were 54.4% and 50.7%, respectively, in the low-LMR subgroup and 84.0% and 76.0% in the high-LMR subgroup. According to multivariate analysis, the LMR was an independent prognostic factor for OS (HR=2.031, 95%CI=1.266-3.258, p=0.003). When comparing the sites of recurrence between the low-LMR and high-LMR groups, there were significant differences in hematologic recurrence, lymph node recurrence, and peritoneal recurrence. Conclusion: Preoperative LMR might be a promising tool for the treatment and management of GC.
