A study presented at the 2005 Digestive Disease Week, by Drs. Takenaka, Okada, et al, showed that patients with peptic ulcers who underwent H. pylori eradication had a reduced incidence of intestinal-type gastric cancer. The incidence of intestinal-type gastric cancer at 1 and 3 years in the eradicated subjects was 0.1% and 0.6% respectively, as opposed to 0.4% and 3.7% in the not-eradicated subjects (p<0.01). In contrast, the incidence of diffuse-type cancer in the eradicated subjects was similar to that in the non-eradicated subjects.
