The Diagnostic Value of Preoperative Hematology Makers in the Classification and Molecular Subtypes of Newly Diagnosed High-Grade Gliomas
Abstract Purpose: The purpose of our study is to explore the diagnostic value of the single and combined hematological maker for the classification and isocitrate dehydrogenase (IDH)-1/2 mutations (IDH) molecular subtypes of high-grade gliomas (HGGs).Methods: A total of 354 newly diagnosed HGGs patients were included in this study. Firstly, we compared the levels of hematology indicators in the classification and molecular subtypes of HGGs. Next, the correlation between the levels of hematology indicators with basic clinical features was analyzed. Finally, the diagnostic value of the single and combined hematology indicator for identifying the classification and molecular subtypes from HGGs was performed.Results: The level of fibrinogen (FIB) was higher in higher grade gliomas and glioblastoma multiforme IDH wild type (GBM IDH-wt). Nutrition-related indicators such as serum albumin (ALB), albumin/globulin ratio (AGR), and prognostic nutrition index (PNI) were negatively correlated with age, whereas FIB was positively associated with age. Compared with women, men with GBM had significantly higher AGR and lower serum globulin (GLOB). We found that the best single and combined indicator for identifying GBM and GBM IDH-wt from HGGs were FIB [0.595 (0.519-0.672) and 0.615 (0.546-0.684)] and age+FIB [0.712 (0.642-0.783) and 0.726 (0.662-0.791)], respectively.Conclusions: Preoperative hematological indicators have high diagnostic value for GBM and GBM IDH-wt from HGGs, especially FIB combined age.
