Intestinal metaplasia of the stomach may raise the risk of gastric cancer by 11 times, with the median time to development of cancer at four years, researchers reported at the ACG Annual Scientific Meeting. Researcher Dr. Andrew Wang of the University of Virginia said the data suggest intestinal metaplasia screening guidelines might be needed, and he noted the lifetime risk of stomach cancer among IM patients may be higher than the risk of Barrett's esophagus progressing to esophageal cancer.
