Clinical experience with CA-50 in the serum of carcinoma patients.
A radioimmunoassay was used for the detection of the human carcinoma-associated antigen CA-50 in the serum of 60 normal subjects, 236 patients with benign disease and 482 patients with carcinomas of different type. Serum levels in all normal subjects and 220 of 236 patients (93%) with benign disease were below 17 units/ml, while 269 of 482 patients (56%) with carcinoma had CA-50 levels above 17 units/ml. This tumour marker may prove useful in the diagnosis and monitoring of patients with various carcinomas.
