Gastric ulcer and risk of cancer. A five-year follow-up study

In 1976, 121 patients with benign gastric ulcer and 13 with gastric carcinoma were diagnosed in our department by endoscopy, cytology and directed biopsies. At a 5-year follow-up, 78 of these patients were re-examined with endoscopy and biopsies. None had developed gastric cancer during the observation time. Of the 78 patients who underwent endoscopy, 16 had gastric ulcer, 2 duodenal ulcer and 27 atrophic gastritis, including 3 with moderate dysplasia of the gastric mucosa. The patients with ulcer had remarkably few symptoms. Only few data are available concerning the postulated link between gastric ulcer disease and gastric malignancy. The cancer-ex-ulcere hypothesis seems to be a medical dogma. However, well planned prospective studies with endoscopic follow-up of gastric ulcers are needed to elucidate the question properly.
