Background: Glioblastoma is one of the most common malignant brain tumors in adults with poor prognosis. Neovascularization is one of the characteristics of these tumors, which is associated with overexpression of vascular endothelial growth factor (VEGF). Accordingly, single nucleotide polymorphisms of this gene could play an important role in structural and functional alterations leading to overexpression of this gene in GBM. Methods: A total number of 49 patients with GBM and 50 healthy controls were included in the current study. The Genomic DNA was extracted from brain tumor/tissue samples, and after purification assessment, the alleles, and genotypes of rs3025039 and rs2010963 polymorphisms of the VEGF gene were investigated using T-ARMS-PCR. Results: The "T" allele of rs3025039 was 2.79 times more frequent in GBM patients compared to controls (P=0.01). Moreover, the "CT" genotype was 2.83 times more common among patients (P=0.015), while the "CC" was more frequent in controls (P=0.009). The mean overall survival was significantly different between three genotypes of rs3025039, with the longest survival time in "CT" genotype (15.10±5.21, P=0.041). Besides, rs2010963, was significantly associated with GBM occurrence, with the "G" allele being 1.96 times more frequent in patients (P=0.01), as well as the "GG" genotype, which was 7.87 times more common in patients (P<0.001). Conclusions: Polymorphisms of VEGF could potentially play a role in pathogenesis of GBM, as the allele and genotype distributions of rs3025039 and rs2010963 SNPs were significantly associated with GBM occurrence.
