MMP-1,EGF, and IL-1B gene polymorphism can be associated with gastric carcinogenesis. However, no study has yet confirmed the definitive role of these gene polymorphisms in gastric cancer risk. The 194 gastric cancer patients, 94 gastric adenoma patients, and 182 controls were used in this study. The SNP of the MMP-1 promoter, EGF, and IL-1B-31 were analyzed by PCR-RFLP and sequencing. The genotype frequency was compared between cases and controls, and a univariate and multivariate analysis were performed to determine the significant risk factors associated with gastric adenoma and adenocarcinoma. The frequency of 1G/2G genotypes in the MMP-1 promoter was similar to those in controls (p=0.734). The frequency of A/G genotypes in the EGF was similar to those in controls (p=0.239). The frequency of C/T genotypes in the IL-1B-31 was similar to those in controls (p=0.239). According to univariate analysis, male sex (p<0.0001), old age (≥60, p<0.0001), atrophy (pepsinogen I/II ≤3, p<0.0001), and G/G genotype of EGF (p=0.034) were significant risk factors associated with gastric adenoma and carcinoma. However, male sex (p=0.002), old age (p<0.0001), and atrophy (p<0.0001) were the only significant risk factors associated with gastric adenoma and carcinoma according to the multivariate analysis. In conclusion, the SNP of the MMP-1 promoter, EGF, and IL-1B-31 did not correlate with the risk of gastric adenoma and adenocarcinoma. Sex, age, and atrophy were the significant risk factors of gastric cancer.
