Abstract:	Aim: Metalloproteinases (MMPs) are a family of multifunctional proteins which have been shown to be up-regulated in various types of cancer. However, the contribution of MMP1 genotype to oral cancer has not been elucidated. This study aimed to evaluate the contribution of MMP1 promoter 1607 genotype to the risk of oral cancer. Materials and Methods: In this case–control study, MMP1 genotype and its interaction with consumption of areca, cigarettes, and alcohol in determining oral cancer risk were investigated in 788 patients with oral cancer and 956 gender-matched healthy controls. Results: The distribution of 2G/2G, 1G/2G and 1G/1G for MMP1 promoter 1607 genotype was 36.8%, 40.2% and 23.0% in the oral cancer group and 34.3%, 44.9% and 20.8% in the non-cancer control group, respectively (p for trend=0.1454). We also analyzed the allelic frequency distributions and found that the variant 1G allele of MMP1 promoter 1607 conferred similar oral cancer susceptibility as the wild-type 2G allele (odds ratio=0.99, 95% confidence interval=0.87-1.14, p=0.9199). As for the gene–lifestyle interaction, there was an obvious protective effect of MMP1 promoter 1607 1G/2G genotype on the risk of oral cancer among smokers (odds ratio=0.71, 95% confidence interval=0.55-0.91, p=0.0076), but not non-smokers. There was no interaction between MMP1 promoter 1607 genotype and areca chewing or alcohol drinking habits. Conclusion: The 1G/2G genotype of MMP1 promoter 1607 may have a protective effect on oral cancer risk for smokers. The detailed mechanisms involved in this require further investigation.
