Dynamics of <i>Helicobacter pylori</i> infection as a determinant of progression of gastric precancerous lesions: 16-year follow-up of an eradication trial

Abstract

Long-term exposure to <i>H. pylori</i> infection was associated with progression of precancerous lesions. Individuals infected with <i>H. pylori</i> with these lesions may benefit from eradication, particularly those with atrophic gastritis without IM. Incomplete-type IM may be a useful marker for the identification of individuals at higher risk for cancer.
