Abstract

Background: Study results on overall seroprevalence of Helicobacter pylori and colorectal cancer risk have been inconsistent. However, one study found positive associations with antibodies to specific H. pylori proteins. To follow up on those findings, we assessed associations of 15 H. pylori specific proteins with colorectal cancer incidence in the prospective Cancer Prevention Study-II Nutrition Cohort. Materials and Methods: Participants in this nested case–control study included 392 cases and 774 controls who were predominantly elderly (median age at blood draw: 71 years) and Caucasian (98%). Seroreactivity against 15 H. pylori proteins was assessed by fluorescent bead-based multiplex serology and associations with colorectal cancer were estimated using conditional logistic regression. Results: Helicobacter pylori serostatus was not associated with colorectal cancer incidence (odds ratio (OR), 1.17, 95% confidence interval (95% CI), 0.91–1.50). Among individual antigens, GroEl serostatus was associated with colorectal cancer risk (OR, 1.32, 95% CI: 1.03–1.70), whereas CagM was associated with colon cancer risk only (OR, 1.35, 95% CI: 1.01–1.80). No dose–response relationships were observed for any of the antigens, including GroEl and CagM. Conclusions: The results of our study do not support an association between H. pylori infection and colorectal cancer risk in this elderly, mostly Caucasian population.
