DNA repair genes are important in maintaining genomic stability and integrity. DNA repair gene polymorphisms, such as those of the human homolog of 8-oxoguanine DNA glycosylase 1 (hOGG1) and excision repair cross-complementing rodent repair deficiency, complementation group 2/Xeroderma pigmentosum complementation group D (ERCC2/XPD), contribute to carcinogenesis. The aim of this study was to investigate the association of prostate cancer (PCa) risk with hOGG1 and ERCC2/XPD genetic variants. A case-control study of 200 cases including 100 PCa patients and 100 healthy subjects was conducted. Two single-nucleotide polymorphisms (SNPs) (ERCC2/XPD Arg156Arg and hOGG1 Ser326Cys) were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The results demonstrated a significant association of the XPD156 homozygous (AA, OR=3.80; 95% CI: 1.19-12.18; P=0.017), heterozygous (AC, OR=2.48; 95% CI: 1.02-6.35; P=0.033) and combined (AA+AC, OR=2.76; 95% CI: 1.18-6.84; P=0.011) mutant genotypes with a predisposition to high-risk PCa. In the stratified analysis, predisposition to high-risk PCa was also associated with the mutant genotypes of hOGG1 326 homozygous mutant (GG, OR=2.93; 95% CI: 1-8.74; P=0.033). The results also showed that the A allele of XPD Arg156Arg and the G allele of hOGG1 Ser326Cys were associated with an increased risk of PCa (OR=1.86 and 1.62; 95% CI: 1.13-3.06 and 1-2.67, respectively). In conclusion, the findings of this study demonstrated that the ERCC2/XPD Arg156Arg and hOGG1 Ser326Cys polymorphisms increased the susceptibility to high-risk PCa.
