Detection of carcinoembryonic antigen of endometrial carcinoma and hyperplasia

The amount and distribution of carcinoembryonic antigen (CEA) was determined in 41 cases of endometrial carcinoma and 23 cases of endometrial hyperplasia using the Avidin-biotin-peroxidase-complex technique. The surface location and amount of CEA in cancer specimens were found to be related to the histological differentiation of tumor. In endometrial hyperplasia, the content of CEA was the same as that of cancer, but the surface location was different.
