Utility of Peripheral Blood Parameters in Predicting Breast Cancer Risk

Abstract

PURPOSE: We aimed to study the inflammatory parameters of complete blood count in breast cancer cases. MATERIALS AND METHODS: This retrospective study covered 178 breast cancer patients and 107 age and body mass index matched healthy women. Complete blood count parameters, neutrophil/lymphocyte ratio (NLR), platelet/ lymphocyte ratio (PLR) and MPV/platelet were analyzed. RESULTS: The leukocyte, neutrophil and neutrophil/ lymphocyte ratio were higher in the patient group (p values 0.001, 0.0001 and 0.0001, respectively) while haemoglobin and hematocrit were higher in the control group (p=0.0001 for both). Logistic regression analysis showed that elevated neutrophils and platelet distribution width (PDW) (OR: 0.627, 95%CI: 0.508-0.774, p=0.001 and OR: 1.191 95%CI: 1.057-1.342 p=0.003) were independent variables for predicting breast cancer. The cut- off value for the neutrophil/lymphocyte ratio was 2.56. CONCLUSIONS: According to our study results, neutrophil levels as part of complete blood count may be used as an independent predictor of breast cancer risk.
