RADIOIMMUNOASSAY FOR CARCINOEMBRYONIC ANTIGEN: ITS APPLICATION TO DIAGNOSIS AND POST‐TREATMENT FOLLOW UP OF HUMAN CANCER A REVIEW

This is a review of the current developments in the study of carcinoembryonic antigen (CEA) and the application of radioimmunoassay for its detection in serum. The detection of CEA represents a valuable test in the diagnosis and post‐treatment follow up of several types of cancer, particularly of the gastrointestinal tract, pancreas, lung, breast and female genital organs, when the results are interpreted in the context of all other clinical information. Caution should be exercised in considering positive results in the presence of hepatic, pancreatic and gastrointestinal disease. Attempts at population “screening” should await more specific reagents and techniques.
