DNA repair gene XRCC3 T241M polymorphism and bladder cancer risk in a Chinese population.
The X-ray repair cross-complementing group 3 (XRCC3), one of the DNA repair genes, was suggested to play an imperative role in the development of carcinogenesis. The objective of this study was to evaluate the role of the XRCC3 T241M polymorphism in bladder cancer susceptibility in a Chinese population. We genotyped 150 bladder cancer cases and 150 healthy controls who had been frequency matched to cases by age and sex. Genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism analysis. A significant association was found between smoker and bladder cancer [odds ratio (OR)=1.97, 95% confidence interval (CI)=1.24-3.13, p=0.004]. The XRCC3 241MM genotype was more frequent in the bladder cancer group than in the healthy controls group (OR=3.22, 95% CI=1.14-9.11, p=0.03). There were no significant associations between any genotypes and the stage, grade, and histological type of bladder cancer. Our study suggested an increased risk role of XRCC3 241MM genotype in bladder cancer susceptibility in a Chinese population.
