Background: Elevation of the neutrophil to lymphocyte ratio (NLR) has been shown to be an indicator of poor prognosis in many malignancies including recurrent glioblastoma multiforme. Objectives: This study was aimed at assessing if the NLR and other leukocyte counts and indices were deranged in treatment-naïve patients with primary brain tumors when compared with an age-matched healthy control group. Materials and Methods: This was a prospective comparative clinical observational study by design. A healthy control population was compared with treatment-naïve patients diagnosed with intra- and extraaxial brain tumors. Leukocyte counts (neutrophil, lymphocyte, monocyte, eosinophil, and basophil counts) as well as leukocyte ratios such as the NLR and the monocyte to lymphocyte ratio (MLR) were calculated. We also evaluated if the counts and indices were related to the tumor volume. Results: In all patients with tumors, the platelet and neutrophil counts were elevated when compared to the controls. In contrast, monocyte counts and the MLR were found to be decreased in patients with tumors when compared to the controls. The subset of patients with glioblastoma showed a significant increase in NLR when compared to the controls. Conclusions: Significant changes in the neutrophil, monocyte, and platelet counts as well as NLR and MLR were observed. Prospective longitudinal studies are required to determine the prognostic and therapeutic implications of these findings.
