The combined results based on all studies suggested that XRCC3 Thr241Met was associated with blad</span>der cancer risk under homozygote and recessive models.
In summary, this meta-analysis suggests the participation of XRCC3 T241M in the susceptibility for bladder cancer and breast cancer, especially in Caucasians, and XRCC3 T241M polymorphism is associated with decreased lung cancer risk.
Taken together, our meta-analysis had suggested an increased risk role of XRCC3 241MM genotype in bladder cancer among all subjects, and the effect of T241M polymorphism on bladder susceptibility should be studied with a larger, stratified population.
We undertook a case-control study of 212 urothelial bladder cancer (UBC) cases and 250 controls to investigate the association between OGG1 (C1245G rs1052133), XRCC3 (C18067T, rs861539) and XRCC7 (G6721T, rs7003908) polymorphisms and bladder cancer susceptibility by PCR-RFLP and the ARMS method.
Gene-environment interaction with arsenic exposure was observed in relation to bladder cancer risk for a variant allele of the double-strand break repair gene XRCC3 T241M (adjusted OR 2.8 (1.1-7.3)) comparing to homozygous wild type among those in the top arsenic exposure decile (interaction p-value 0.01).
