Gastrin and somatostatin-like immunoreactivity (SLI) levels were studied by means
of radioimmunoassay in peripheral venous blood of healthy volunteers and patients
suffering from gastric adenocarcinoma or duodenal and gastric ulcers. Gastrin and
SLI levels were also evaluated in patients in blood drawn from gastric veins during
surgery. The elevations of gastrin and SLI levels were found in patients with gastric
cancer as compared with healthy people and patients suffering from ulcers. The impairment
of the negative feedback between gastrin and somatostatin secretions in patients with
gastric cancer was suggested.
