Radioimmunoassay of carcinoembryonic antigen was conducted in lung cancer patients before and after surgery. Elevated concentrations of the antigen before operation was registered in 84.8% of cases. Antigen levels returned to normal after radical removal of tumor and rose sharply as a result of chemotherapy toxicity. A similar pattern of changes in carcinoembryonic antigen level was observed in cases of disseminated and recurrent cancer.
