Elevated platelet lymphocyte ratio is a poor prognostic factor in advanced epithelial ovarian cancer

초록

The platelet lymphocyte ratio (PLR) is an important prognostic biomarker in various cancers. The current retrospective study was undertaken to determine the association between PLR and prognosis of advanced epithelial ovarian cancer. We determined the optimal cutoff values of PLR for predicting survival outcomes using the receiver operating characteristic curve analysis. Based on the PLR cutoff values, patients were divided into two groups: <226 and ≥226. Univariate analysis revealed a greater risk of death in the PLR ≥ 226 group than the PLR < 226 group (HR (hazard ratio), 2.7; 95 % CI (confidence interval), 1.3–5.4; P = 0.006). In multivariate analysis, PLR (HR, 1.9; 95 % CI, 1.1–3.6; P = 0.047) significantly affected the overall survival. Our data indicates that PLR can be used as an independent significant prognostic factor in advanced epithelial ovarian cancer. © 2020 Elsevier Masson SAS
