title: [Radioimmunoassay of carcinoembryonic antigen, gastrin and immunoglobulin E in evaluating different methods of treatment of patients with esophageal and stomach cancer].
abstract: A radioimmunoassay of the carcinoembryonic antigen, gastrin and immunoglobulin E was performed in the blood serum of more than 300 esophageal and gastric cancer patients. It has been noted that the CEA study makes it possible to determine the severity of disease and may serve as a yard-stick of radical therapy. Hypogastrinemia develops in 82-84% of patients with tumors of these sites. The gastrin level after therapy depends on the nature and type of antitumor therapy. An increase in the IgE level is a risk factor which makes it possible to identify patients with an "unfavorable" or complicated course of disease and to determine, to some extent, prognosis, to control therapeutic measures in combined treatment. The use of the radioimmunoassay for CEA, gastrin and IgE in the combined study of esophageal and gastric cancer patients allows one to evaluate the patients's status before treatment and to determine their response to tumor therapy.
