ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the association between the polymorphisms of X-ray repair cross complementing group 1 (XRCC1) and human 8-oxoguanine glycosylase I (hOGG1) gene and the risk for laryngeal carcinoma.</p><p><b>METHODS</b>This is a case-control study comprised of two groups 72 patients with laryngeal squamous carcinoma, and 72 controls without laryngeal carcinoma. The PCR-restriction fragment length polymorphism method was used to analyze the XRCC1-Arg399Gln, hOGG1-Ser326Cys polymorphisms.</p><p><b>RESULTS</b>The frequencies of XRCC1-399Arg/Gln+ Gln/Gln and hOGG1-326Ser/Cys+ Cys/Cys genotypes in the case group were higher than that of the control group(P< 0.05). There was a 3.37-fold or 2.54-fold increased risk of laryngeal carcinoma for individuals carrying XRCC1-399Arg/Gln+ Gln/Gln or hOGG1-326Ser/Cys+ Cys/Cys genotypes, compared with subjects carrying XRCC1-Arg/Arg or hOGG1-Ser/Ser genotype, respectively. No statistically significant differences were found between the smoking group and non-smoking group for risk of laryngeal carcinoma.</p><p><b>CONCLUSION</b>The amino acid replacement of XRCC1-399Arg to Gln and hOGG1-326Ser to Cys might lead to an increased risk of laryngeal carcinoma. The study demonstrated the positive association between the polymorphisms of XRCC1 and hOGG1 genes and laryngeal carcinoma.</p>
