Influence of Patients’ Ethnicity on the Gastric Biopsy Sampling Patterns

Although the Sydney System protocol requires separate biopsy sampling from antrum, incisura, and corpus, less than 4% of U.S. endoscopists adhere to these recommendations.

There are significant differences in the prevalence of H. pylori and gastric preneoplastic lesions amongst the major ethnic groups in the United States. These differences tend to parallel the reported incidence rates of gastric cancer in the ancestral countries.

It is unclear whether U.S. gastroenterologists serving multicultural populations are aware of and take into consideration their patients’ ethnic origin in the approach to the prevention and early detection of gastric cancer. Specifically, it is unknown whether they adjust their biopsy sampling practice for the maximal detection of preneoplastic gastric lesions in these groups.
