This meta-analysis study demonstrated that a low lymphocyte-to-monocyte ratio (LMR) is significantly associated with poor overall survival (OS) in glioma patients. However, there is no significant correlation between LMR and progression-free survival (PFS) in glioma patients. Subgroup analysis indicated that a low LMR is significantly associated with inferior OS and PFS in glioma when using a cutoff value of <= 3.7 or when patients received mixed treatment.
BackgroundMany studies have explored the prognostic role of the lymphocyte-to-monocyte ratio (LMR) in patients with glioma, but the results have been inconsistent. We therefore conducted the current meta-analysis to identify the accurate prognostic effect of LMR in glioma.MethodsThe electronic databases of PubMed, Web of Science, Embase, and Cochrane Library were thoroughly searched from inception to July 25, 2023. The pooled hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated to estimate the prognostic role of LMR for glioma.ResultsA total of 16 studies comprising 3,407 patients were included in this meta-analysis. A low LMR was significantly associated with worse overall survival (OS) (HR = 1.35, 95% CI = 1.13-1.61, p = 0.001) in glioma. However, there was no significant correlation between LMR and progression-free survival (PFS) (HR = 1.20, 95% CI = 0.75-1.91, p = 0.442) in glioma patients. Subgroup analysis indicated that a low LMR was significantly associated with inferior OS and PFS in glioma when using a cutoff value of <= 3.7 or when patients received mixed treatment.ConclusionsThis meta-analysis demonstrated that a low LMR was significantly associated with poor OS in glioma. There was no significant correlation between LMR and PFS in glioma patients. The LMR could be a promising and cost-effective prognostic biomarker in patients with glioma in clinical practice.
