NCT05021029

Brief Summary

To establish a prospective cohort of individuals diagnosed with gastric pre-malignant conditions (chronic gastritis, atrophic gastritis, autoimmune gastritis, intestinal metaplasia, intestinal dysplasia) to monitor and study disease progression. The Investigators will like to survey cohort participants for lifestyle behaviors and environmental exposures associated with gastric pre-malignancy and cancer. Analyzing patient biospecimens to identify and characterize host and microbiome biomarkers associated with initiation and progression of gastric pre-malignancies.
