Abstract

It is known that many genomic and genetic alterations caused by aging or environmental factors are responsible for cancer development and progression. XRCC1 is involved in the repair of DNA single-strand breaks formed by exposure to ionizing radiation and alkylating agents. The objective of this study was to investigate the association of genomic alterations and the susceptibility of testicular germ cell tumors with XRCC1 polymorphisms. Two polymorphisms of XRCC1, Arg194Trp and Arg399Gln, were genotyped in 83 patients with testicular germ cell tumors (TGCT) and 87 male controls. Allelic imbalances (AI) were evaluated using 4 microsatellite markers in a subgroup of 50 patients. Patients with at least one Gln allele of the Arg399Gln polymorphism had an increased risk of TGCT than those with the Arg/Arg genotype (aOR=1.775, 95% CI=1.045-3.016, P=0.034). Furthermore, the increased risk associated with the Gln allele against the Arg homozygote was more strongly observed in patients with pure seminoma (aOR=2.242, 95% CI=1.149-4.374, P=0.018) or with metastasis (aOR=2.481, 95% CI=1.267-4.862, P=0.008). In the Arg194Trp polymorphism, there was no significant difference in the genotype distribution between TGCT patients and the controls. In AI analysis, the frequency of AI was significantly higher in tumors with at least one Gln allele than those with the Arg/Arg genotype in D13S317 (P=0.010) and in a combination of 4 markers (0.51±0.32 vs 0.32±28, P=0.028). Our results suggest that the Gln allele of the XRCC1 Arg399Gln polymorphism may genetically modify the development and progression of TGCT through genomic instability.
