Purpose: The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have recently been evaluated in many cancers in prediction of survival outcomes. The purpose of this study was to investigate the impact of NLR and PLR on the prognosis of patients with epithelial ovarian cancer (EOC). Materials and Methods: A total of 208 patients with EOC were included in the study. Hematological parameters and clinicopathological data during diagnosis were retrospectively evaluated. The cut-off values were determined by calculating receiver operating characteristic (ROC) curve analysis of the patients. Results: The median overall survival (OS) of patients with low NLR was 69 months (95% CI, 43.0-94.9) whereas high NLR was 36 months (95% CI, 29.1-42.8). The median OS with low PLR patients was 76 months (95% CI, 46.4-105.5) and high PLR was 35 months (95% CI, 28.5-41.4). In serous tumors (70.7%), the median OS with low NLR and high NLR was 54 months (95% CI, 27.9-80.0) and 34 months (95% CI, 28.2-39.7), and for the median OS with low PLR and high PLR it was 51 months (95% CI, 21.2-80.7) and 35 months (95% CI, 27.8-42.1), respectively. Conclusion: The present findings showed that the high NLR and high PLR were associated with poor prognosis and these values are significantly remarkable in EOC patients.
