Abstract

Helicobacter pylori infection, the dominant risk factor for gastric cancers, has been shown to elicit T helper type 1 (Th1) polarized immunological responses. We conducted a population-based study of 305 gastric cancer cases and 427 age- and gender-matched controls in Warsaw, Poland, to evaluate the association with several variants in genes responsible for Th1-cell-mediated response. Genotyping was performed on genomic DNA by TaqMan(TM) assays to determine TNFA (-308 G > A, -417 G > A, -555 G > A, -1036 C > T, -1042 C > A, -1210 T > C), IL1A (-889 C > T), IFNGR2 (Ex7-128 T > C, Ex2-34 C > G and Ex2-16 A > G) and IL12A (IVS2-798 T > A, IVS2-701 C > A and Ex7+277 G > A) polymorphisms. We used unconditional logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs), adjusting for sex, age, education and smoking status. Out of six single nucleotide polymorphisms (SNPs) tested in TNFA, gastric cancer risk was significantly associated with the TNFA (-308 G > A) polymorphism, with ORs of 1.4 (95% CI: 1.0-2.0) for the G/A and 2.5 (95% CI: 1.3-4.9) for the A/A genotype carriers, when compared with the more frequent genotype (G/G) (P-trend < 0.001). Among the three tested SNPs in the IFNGR2 gene, only the Ex7-128C > T polymorphism was associated with increased risk, with ORs of 1.5 (95% CI: 1.0-2.3) for T/C and 1.7 (95% CI: 1.1-2.7) for C/C carriers when compared with T/T carriers (P-trend = 0.01). Subjects carrying both IFNGR2 Ex7-128 C/C and TNFA -308 A/A genotypes had the highest risk (OR = 5.5, 95% CI: 1.5-19.4), although the interaction was not statistically significant. IL1A (-889 C > T) and the three examined IL12A variants were unrelated to gastric cancer risk. Our findings suggest that two Th1-related polymorphisms (TNFA -308 A > G and IFNGR2 Ex7-128 C > T) may increase the risk of gastric cancer.
