title: Carcinoembryonic antigen in serum, urine and cells of patients with bladder carcinoma.
abstract: A raised level of CEA-like substance has been demonstrated by radioimmunoassay in the urine of patients with bladder carcinoma, in concentrations which increase with a more advanced stage, and in serum of patients with advanced disease. In a 2-year follow-up of patients receiving chemotherapy, a correlation of raised urinary CEA to local recurrence was seen, as well as rising and high serum values with metastases. In the patients who responded to treatment, CEA values became normal. CEA was also located in carcinoma cells from bladder washings in 24--61% of the cases. Combined studies of CEA in serum, urine and cells may be used to study the biology of the tumour and perhpas also in the monitoring of patients with urothelial carcinoma.
