Plasma and urinary carcino-embryonic antigen (CEA) assays were performed in 151 patients with urological tumours. CEA measurement is unreliable in renal cell carcinoma and carcinoma of the prostate. However, CEA-assays permit the diagnosis of bladder tumours. The test is particularly useful in the followup and therapeutic control of patients with carcinoma of the bladder.
