It indicated that XRCC1 R399Q and R194W might not be risk factors to bladder cancer, but the 399QQ genotype decreased susceptibility of bladder cancer under recessive model and homozygote contrast among ever-smokers.
For Arg(194)Trp (six studies, 3091 cases, 3219 controls), no evidence indicated that individuals carrying the variant genotypes (Trp/Trp + Arg/Trp), relative to those carrying the wild homozygote Arg/Arg genotype, had a decreased risk of bladder cancer (odds ratio [OR] 0.90, 95% confidence interval [CI] 0.77 to 1.05; P = 0.17).
We provide no evidence of an association between polymorphisms in XRCC1 and bladder cancer risk, although our study had only limited power to detect the association for low frequency variants, such as Arg280His.
APEX1 rs3136817, MUTYH rs3219493, three SNPs (rs3213356, rs25487 and rs1799782) in XRCC1, and three SNPs (rs1799794, rs861531 and rs861530) in XRCC3 showed significant associations with the risk of bladder cancer.
The aim of this study was to examine the association between polymorphisms of DNA repair genes, namely X-ray repair cross-complementing group I (XRCC1) rs2854509 and rs3213255, and bladder cancer recurrence risk.
