101 patients with urologic malignancies were studied for the presence of plasma carcinoembryonic antigen (CEA) employing the radioimmunoassay technique of Hansen. 59% of prostate cancer patients, 76% of bladder cancer patients and 33% of renal cancer patients were CEA positive. There were more positive CEA determinations in patients with higher stage and grade tumors. There were more false positives and false negatives among those patients receiving hormones or radiation.-In summary CEA appears to be present in patients with urologic malignancies. Care should be taken in interpreting CEA results in patients receiving hormones or radiation.
