The neutrophil-to-lymphocyte ratio (NLR) has prognostic value in patients with a variety of cancers. The purpose of this study was to investigate the prognostic value of NLR in patients with glioblastoma. Methods: A prospective study was conducted on patients receiving surgery for glioblastoma. Preoperative NLR was recorded and correlated with other prognostic factors and survival. Results: Fifty-one patients were included in the study. The mean NLR ratio was 6.7 ± 4.6. Using receiver operating characteristic curve analysis, an NLR cut-off value of 4.7 was determined to best predict survival. Patients with NLR ratios exceeding 4.7 differed significantly from those with NLR ratios ≤ 4.7 and were associated with reduced survival. Patients with gross total tumor excision had a median survival of 18 months, whereas the median survival time was 11 months in patients with subtotal tumor excision. No significant difference in survival was observed with respect to patient age, gender, Karnofsky performance status, or tumor location. Using multivariate analysis, NLR and extent of tumor resection were identified as factors with independent prognostic power. Conclusion: Neutrophil-to-lymphocyte ratio is an inexpensive, widely available biomarker of glioblastoma aggressiveness and should be used alongside current glioblastoma prognostic factors.
