Abstract
The goals of this study included an analysis of the incidence of single nucleotide polymorphisms (SNPs) genotypes and alleles in DNA repair genes and evaluation of the effects by which this genetic variability may influence the risk for endometrial cancer. The study group included 610 women with endometrial cancer and was compared with a quantitatively matched control group of 610 women without any diagnosed malignancy. The following polymorphisms were analyzed: X-Ray repair cross complementing 1 (XRCC1)-Arg399Gln (rs25487); XRCC2-Arg188His (rs3218536); XRCC3-Thr241Met (rs861539); ERCC excision repair 2, TFIIH core complex helicase subunit (ERCC2)-Lys751Gln (rs13181); and 8-oxoguanine DNA glycosylase (OGG1)-Ser326Cys (rs13181). Allele XRCC2-188His [odds ratio (OR)=5.24, 95% confidence interval (CI)=4.36-6.29; p<0.0001], hOGG1-326Cys (OR=1.60, 95% CI=1.36-1.88; p<0.0001) and ERCC2-751Gln (OR=1.67, 95% CI=1.42-1.96; p<0.0001) strongly correlated with neoplastic disease. The evaluated SNPs may be approached as a group of new risk factors for the development of this cancer type.
