Materials and Methods: In this hospital-based case-control study, the association of Ku80 G-1401T rs828907, Ku80 C-319T rs11685387 and Ku80 intron 19 rs9288518 polymorphisms with bladder cancer risk in a central Taiwanese population was investigated. In total, 288 patients with bladder cancer and 288 age- and gender-matched healthy controls recruited from the China Medical Hospital in central Taiwan were genotyped. Results: A significantly different distribution was found in the frequency of the Ku80 G-1401T polymorphism genotypes, but not the Ku80 C-319T or intron 19 polymorphism genotypes, between the bladder cancer and control groups. The T allele of Ku80 G-1401T conferred a significant (p=0.0055) increased risk of bladder cancer. Gene-environment interactions with smoking, but not with alcohol consumption, were significant for the Ku80 G-1401T polymorphism. The Ku80 G-1401T GT and TT genotypes, in association with smoking, conferred an increased risk of 2.053-fold (95\% confidence interval=1.232-3.419) for bladder cancer. Conclusion: The first evidence that the T allele of the Ku80 G-1401T may be associated with the development of bladder cancer and may be a novel useful marker for primary prevention and anticancer intervention is provided.}, issn = {0250-7005}, URL = {https://ar.iiarjournals.org/content/29/4/1275}, eprint = {https://ar.iiarjournals.org/content/29/4/1275.full.pdf}, journal = {Anticancer Research} }
