Carcinoembryonic Antigen in the Urine of Patients with Urothelial Carcinoma

Abstract

Increased amounts of carcinoembryonic antigen (C.E.A.) or C.E.A.-like material are found in the urine of many patients with transitional cell carcinomas of the bladder, including those presumed to be at an early stage of development. It is suggested that measurement of urinary C.E.A. is of clinical diagnostic value in the detection and follow-up of urothelial carcinomas.
