Individuals infected with certain strains of the Helicobacter pylori bacterium and who have specific genetic polymorphisms are more likely to develop stomach cancer, say US researchers. The 443-patient study, conducted at the University of Porto, Portugal, found that people with a high-activity version of the interleukin-1 beta gene who were infected with H Pylori with a particular variant of the vacA vacuolating cytotoxin had a nearly 90-fold increase in risk of stomach cancer. The findings appear in the Journal of the National Cancer Institute (November 20).
