Most epithelial neoplasms of the ovary also express carcinoembryonic antigen (CEA). The neoplasms include, with decreasing intensity and frequency, Brenner, endometrioid, clear cell, and serous tumors. CEA is frequently present in patients with cancer that has metastasized to the ovary because the primary cancer is generally mammary or gastrointestinal in origin and these tumors frequently express CEA.
