[Value of carcinoembryonic antigen (CEA) in the diagnosis of malignant tumors of the urogenital tract].

Both in a control group and in 154 patients with malignant tumors of the urogenital tract in the serum- and urinary levels of the carcinoembryonic antigen (CEA) have been ascertained by a radioimmunoassay. Serum-CEA-values lay above normal range in 71%, and urinary CEA-levels exceeded it in 46%. Only in the case of the carcinoma of the bladder a correlation was found between the CEA-curves and the clinical findings following tumor therapy. Up to the present, the CEA-test cannot be recommended as a universal screening method, but may be useful means for diagnostics and case controls, above all, with regard to the carcinoma of the bladder.
