Abstract
Cases with central nervous system tumors represent a small amount of all tumors, and the diagnosis of high-grade gliomas (HGGs) is mostly difficult as they frequently show intratumoral morphological heterogeneity. Genetic factors, such as single nucleotide polymorphisms (SNPs), have an important role in modifying glioma susceptibility. We conducted a comprehensive meta-analysis to investigate the ERCC1 (rs3212986), ERCC2 (rs13181), XRCC1 (rs25487), and XRCC3 (rs861539) genes to see if they are any risk factors for glioma susceptibility. We identified 30 eligible studies investigating the PubMed records (up to January 2024) via a mishmash of the subsequent terms: brain tumors, glioma, glioblastoma, gene associations, SNPs, XRCC1, XRCC3, ERCC1, and ERCC2. The total number of patients was 23678 (9731 in cases (poor outcome) and 13947 in controls (good outcome)). This comprehensive meta-analysis declared a significant association between ERCC2 rs13181, XRCC1 rs25487, and the risk of glioma.
