Abstract
The relationship between peptic ulceration and gastric carcinoma has been examined using data from two large autopsy surveys. The first consisted of over 13,000 autopsies performed in a single hospital over a 20-year period and analysed retrospectively; the second was a prospective series of over 7000 autopsies carried out at 17 centres during a single year. In both, a lower than expected occurrence of coexistent gastric cancer was found in subjects with pathologic evidence of active or past gastric and duodenal ulceration. A statistical association between chronic gastric ulcer and lung cancer was noted. This study has failed to identify an increased risk of gastric carcinoma in patients with chronic gastric ulcer.
