Clinical Significance

CEA belongs to a group of tumor markers referred to as oncofetal proteins. Increased serum CEA levels have been detected in persons with primary colorectal cancer and patients with other malignancies including gastrointestinal tract, breast, lung, ovarian, prostatic, liver, and pancreatic cancers. Elevated serum CEA levels have also been detected in patients with nonmalignant disease, especially patients who are older or who are smokers. CEA levels provide important information about patient prognosis, recurrence of tumors after surgical removal, and effectiveness of therapy.
