It was clear that in the developing world, gastric ulcer and gastric cancer were more common than in the developed world where duodenal ulcer predominated. This correlated with the distribution of gastritis in duodenal ulcer patients where the inflammation was antral predominant while in gastric ulcer patients the gastritis was more evenly distributed through the stomach. Gastric ulcers usually appeared in a fairly restricted distribution in the stomach near the angulus and close to the transitional zone between antrum and body mucosa.

In terms of both incidence and mortality, it ranks second in importance after lung cancer. In 1990, there were estimated to be 798,000 new diagnoses and 752,000 deaths from gastric cancer worldwide, representing 9.9% of all new cancers. Sixty percent of these cancers occur in the developing world, 62% in Asia and 12% in Japan.展开更多
