Long-term proton pump inhibitor administration, H pylori and gastric cancer: lessons from the gerbil by Fox, James G., Kuipers, Ernst J.

“…The association between chronic active gastritis and pre-neoplastic conditions as well as invasive cancer of the stomach was established several decades ago. The risk of progression depended on the severity and distribution of gastritis, with cancer, in particular, occurring in subjects with pan-gastritis. …”
