ABSTRACT
<p><b>OBJECTIVE</b>To study the association between polymorphism of DNA repair gene xeroderma pigmentosum G (XPG) Asp1104His and the risks of developing laryngeal and hypopharyngeal carcinomas.</p><p><b>METHODS</b>Totally 175 patients with laryngeal or hypopharyngeal carcinoma and 525 cancer-free controls were genotyped for the polymorphism by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The odds ratio (OR) and 95% confidence interval (CI) were calculated using unconditional logistic regression model.</p><p><b>RESULTS</b>Compared with those having the Asp/Asp genotype, patients having the XPG 1104Asp/His genotype had a higher risk for laryngeal carcinoma (OR = 2.46, 95% CI = 1.15-5.24, P < 0.05), but not for hypopharyngeal carcinoma (OR = 1.36, 95% CI = 0.87-2.12, P > 0.05). In addition, the XPG 1104Asp/His genotype appeared to be associated with well differentiated squamous cell carcinoma in both larynx and hypopharynx (OR = 1.88, 95% CI = 1.05-3.40, P < 0.05 ).</p><p><b>CONCLUSION</b>The XPG Asp1104His polymorphism may play a role in the development of laryngeal and hypopharyngeal carcinomas.</p>
