Evaluation of prognostic and predictive values of hemogram parameters in patients with advanced stage ovarian carcinoma

Abstract

OBJECTIVE The aim of the present study was to evaluate the impact of conventional hemogram parameters as a biomarker in epithelial ovarian cancer (EOC) patients; and the clinical importance of the difference after chemotherapy. METHODS We have evaluated the patients with advanced-stage EOC who diagnosed between January 2012 and December 2017. RESULTS Elevated levels of neutrophils, neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio at the time of diagnosis were significantly associated with excess amount of ascites. Lower levels of neutrophils and hemoglobin (HGB); and higher levels of red cell distribution width (RDW), and RDW/HGB ratio were predictors of platinum-sensitivity. In univariate analysis, while decreased mean platelet volume (MPV) was associated with longer disease free survival (DFS); elevated RDW, decreased neutrophils, MPV, and NLR were effective for better overall survival (OS). In multivariate analysis, platinum sensitivity and MPV were significantly associated with DFS and OS. Importantly, patients with persistently low MPV group after chemotherapy had the best OS; while persistently high MPV group had the worst OS. CONCLUSION MPV is a marker that can be easily evaluated during complete blood counts, and might be a promising and practical prognostic biomarker in the field of EOC. Hemogram parameters are found useful to predict disease properties and survival in EOC.
