The simultaneous expression of human chorionic gonadotropin and carcinoembryonic antigen in the female genital tract. Localization by immunocytochemistry.

Abstract

Tissue from 180 gynecologic disorders were studied for the simultaneous expression of HCG and CEA, utilizing the immunoperoxidase technique. Of the total population, 0.5% expressed both antigens, 8.8% expressed only hCG, and 5.5% expressed only CEA; 85% expressed neither. The greatest variability of marker expression was among the ovarian and endometrial neoplasms.
