A radioimmunoassay system was developed for the carcinoembryonic antigen of the digestive tract, using a highly purified radioactive antigen. This was used for the assay of serum specimens from 105 patients. Fourteen normal control subjects had a mean serum carcinoembryonic antigen of 1.6 ng/ml. In forty-three patients with proved cancer of the rectum or colon it was possible to classify the state of the disease by a modification of the classification proposed by Dukes. The mean serum carcinoembryonic antigen in these 43 patients was 11.2 ng/ml. Of the 43 patients, 10 were classified as stage A, 8 as stage B,
