OBJECTIVE: Several polymorphisms in DNA repair genes have been extensively studied in association with various human cancers, including laryngeal cancer. The present study aimed to investigate the association between polymorphisms of the XRCC1 gene and laryngeal cancer in a Chinese population. METHODS: Five polymorphisms of the XRCC1 gene (rs3213403, rs1799778, rs1001581, rs3213282, and rs3810378) were genotyped by TaqMan in 234 patients with larynx cancer and 230 age- and sex-matched controls without cancer. RESULTS: The rs3213403, rs1799778, and rs3213282 polymorphisms of XRCC1 were associated with larynx cancer. Haplotype analysis indicated that CCA (odds ratio [OR], 5.707; 95% confidence interval [CI], 3.277-9.938; p<0.001), TGG (OR, 4.344; 95% CI, 2.804-6.732; p<0.001), ACA (OR, 1.615; 95% CI, 1.159-2.250; p=0.004), and GCG (OR, 1.702; 95% CI, 1.164-2.489; p=0.005) were associated with an increased risk for larynx cancer, respectively. However, TGA (OR, 0.518; 95% CI, 0.398-0.673; p<0.001) and ACC (OR, 0.314; 95% CI, 0.215-0.457; p<0.001) were associated with a decreased risk for larynx cancer. CONCLUSIONS: The results indicated that XRCC1 genetic polymorphisms were associated with larynx cancer in a Chinese population.
