    Abstract:
    In patients with gastric cancer who were to undergo gastrectomy, the fasting serum gastrin concentration in the peripheral vein was estimated by radioimmunoassay. The blood samples were also collected from the gastric veins and artery during the time of operations. These gastrin values were compared with morphological findings in the resected stomach. No significant differences in serum gastrin concentration was found between the patients of gastric cancer and normal subjects. In the patients with mucosal atrophy in the oxyntic gland area but with no atrophy in the pyloric gland area, however, significant increase in serum gastrin concentration was observed. In cases where fundal atrophy was accompanied by atrophy in the pyloric gland area, the increase was not observed. The amount of gastrin content in cancer tissue was negligible. These results indicate that the increase in serum gastrin concentration in some patients with gastric cancer might be due to the accompanied atrophy of oxyntic glands in the stomach.
