In this study, we attempted to assess the association between XRCC1 Arg194Trp, Arg280His and Arg399Gln polymorphisms and risk of laryngeal cancer in a Chinese population.
Overall, our results found that only AA genotype of the XRCC1 gene Arg399Gln polymorphism under the homozygous model was associated with increased the risk of patients with laryngeal cancer (AA vs. GG: OR=1.29, 95% CI=1.00-1.65, P=0.05).
