Inflammatory markers, including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and plasma viscosity (PV) are commonly used in primary care for diagnosis and monitoring of inflammatory conditions, including infections, autoimmune conditions, and cancers.
Hematologic inflammatory markers are simple, inexpensive prognostic markers for various conditions. The prognostic significance of representative markers neutrophil to lymphocyte ratio (NLR), Platelet-to-lymphocyte ratio (PLR), monocyte lymphocyte ratio (MLR) and red cell distribution width (RDW) in patients exist in a variety of tumors.
Inflammatory response plays a vital role in the pathological mechanism of intracerebral hemorrhage. It has been recently reported that neutrophil to lymphocyte ratio (NLR) could represent a novel composite inflammatory marker for predicting the prognosis of intracranial hemorrhage (ICH).
A retrospective chart review study was conducted for 219 glioma patients between January 2012 and January 2017. The values of the NLR, PLR, MLR and RDW on the prognosis were evaluated. And correlations between these hematologic inflammatory markers were examined.
Patients were divided into high and low groups according to cutoff points from the receiver operating characteristic curve. The high NLR groups were associated with tumor grade (p = 0.000). Kaplan-Meier survival analyses shown that the high NLR group experienced inferior median survival compared with the low NLR group (11 vs. 32 months; p = 0.000). The high PLR group experienced inferior median survival compared with the low PLR group (12 vs. 21 months; p = 0.001). The high MLR group experienced inferior median survival compared with the low MLR group (12 vs. 22 months; p = 0.006). However, there was no significant difference in median survival between the high and low RDW groups (15 vs. 23 months; p = 0.184). Multivariate analysis demonstrated that NLR was an independent predictor for overall survival (OS) (HR 1.758; p = 0.008).
High preoperative NLR, PLR, MLR were predictors of poor prognosis for patients with glioma. NLR was an independent prognostic factor for OS in glioma 1).
