Gastric foveolar hyperplasia in patients with cancer of the intact stomach.

The incidence of gastric foveolar hyperplasia, a reliable histological marker of bile reflux into the stomach, was evaluated in patients with cancer of the intact stomach. Lesions classified as foveolar hyperplasia were found in 17 of 32 gastric cancer patients and in seven of 30 controls. This difference was statistically significant (p < 0.02). Differences in the incidence of foveolar hyperplasia according to sex, tumor site, attendant chronic atrophic gastritis, and alcohol consumption were not significant, which lends support to the association of gastric cancer with duodenogastric reflux.
