Abstract

Abstract Background There are significant gaps in our understanding of the pathogenesis of glioma and how to treat it clinically. One of the substantial gaps is effectively treating low-grade glioma (WHO II and IIILGG) to increase survival and decrease the progression to high-grade glioma (WHO IV). Although patients with LGG have a better prognosis than those with highgrade gliomas, all LGG progress to high-grade glioma and death. Genomics has a scarcity that compiles all immunooncology targets for translational research and drug discovery for early stages of cancers. Our study reveals a new genes survival prognostic model from recent Immune checkpoint inhibitors (ICIs) databases for glioma cancer. Methods The Cancer Genome Atlas TCGA transcriptomic analysis and matching ICIs genes from the checkpoint therapeutic target database (CKTTD) identify new particular ICI gene signatures for LGG survival analyses. Analysis by using the survival package in R software. A deep genetic and cellular network prediction model was also developed. Results CKTTD showed significant Cox regression for overall survival with adjusted clinical variables in low-grade glioma. 10 ICI genes were supposed to be as risk gene signatures (considered only Pvalue ≤0.001) in LGG; these genes have higher sensitivity testing in one, three, and fifth-year AUC (89%, 86%, and 75%). We further investigated the prediction of the resulting gene by a novel nomogram, which highly detected the risk of death. CCR5 gene expression was significantly associated with grading in LGG patients. Additional validation of CCR5 from GEO was obtained as external validation.
