Recent molecular epidemiological studies have demonstrated that the human oxoguanine glycosylase 1 (OGG1) gene polymorphism may be associated with various cancers. To determine whether the OGG1 Ser326Cys polymorphism interacts with clinicopathological parameters including smoking and alcohol intake in head and neck squamous cell carcinoma (HNSCC), DNA samples from 192 patients with primary HNSCC were genotyped and studied by the case-only design. We observed an association between the Cys/Cys genotype and HNSCC with cigarette smoking of more than 40 pack-years by a multivariate logistic regression analysis (OR=8.10, 95% CI=1.06-61.73). No significant association of this genotype with alcohol intake was observed. Our present data suggest a possible interaction between the OGG1 Ser326Cys polymorphism and smoking in HNSCC.
