N2 - Mucosal atrophy of the gastric antrum (type B atrophic gastritis) is generally accepted as predisposing to the development of the intestinal type of gastric cancer. Since bombesin stimulates gastrin release selectively from the antral mucosa, the response can be used as a marker for antral mucosal atrophy. In this study we have investigated bombesin-stimulated plasma gastrin responses in 21 patients with the intestinal type of gastric cancer and we have compared the results with 12 patients with the diffuse type of gastric cancer, 17 patients with benign gastric ulcer, and 30 dyspeptic patients without endoscopical or histological abnormalities. Gastrin concentrations were also measured in extracts of antral biopsies. Basal plasma gastrin concentrations were not significantly different. In contrast, patients with the intestinal type of gastric cancer had a significantly lower plasma gastrin response to bombesin than did the normal subjects (P 0.01) and patients with the diffuse type of gastric cancer (P 0.05), but the result was not significantly different from that of the gastric ulcer patients. The antral gastrin content of the patients with the intestinal type of gastric cancer was significantly lower than in controls (P 0.005), the patients with the diffuse type of gastric cancer (P 0.05), and those with gastric ulcer (P 0.05). It is concluded that patients with the intestinal type of gastric cancer have, in contrast to those with the diffuse type of gastric cancer, an abnormally low plasma gastrin response to bombesin. This low response is due to a reduced gastrin content of the antral mucosa.
