Aim: To investígate the relationship between selected interleukin-1 (IL-1) loci polymorphisms and gastric cancer risk in the Central-Western región of Venezuela, where gastric cancer represents the first cause of cancer-related deaths. Material and methods: In a case-control study we compared the frequencies of IL-1B-511 and IL-1B+3954 biallelic polymorphism, and the pentallelic VNTR of IL-IRN in 84 gastric adenocarcinoma parafñn-embedded biopsies and 84 endoscopic biopsies from cancer-free controls. Results: No significant increase in genotypic frequencies in gastric cancer was observed for any ofthe IL-1B-511 allelic combinations. However, in a logistic regression analysis, a significant association emerged for the IL-1B+3954C carrier genotype (odds ratio (OR): 6.2; 95% confidence intervals (CI) 1.3-28.8). On the other hand, a significantly higherrisk was evidenced for the IL-IRN*2/*2genotype (OR: 7.0; 95% CI2.3-21.5). Onlypatients with a well/moderately-differentiated adenocarcinoma that were homozygotes for the E-IRN*2/*2 genotype, liad a higher risk than the complete gastric cancer group (OR: 8.1, 95% CI 2.5-26.8). Some genotype combinations among IL-1B-511, IL-1B+3954 and IL-IRN showed an increased risk for developing gastric cancer and well/moderate differentiated adenocarcinoma, that was dependent ofthe presence of IL-IRN*2/*2 genotype. Conclusions: IL-IRN*2/*2 genotype is associated with increased risk of gastric cancer in the Venezuelan population.info:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.137 n.1 20092009-01-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98872009000100009es10.4067/S0034-98872009000100009 |
