CEA is sometimes called a tumor marker or tumor antigen. Tumor markers are substances that some cancer cells make and shed into bodily fluids at times. Healthy cells also may make tumor markers in very low levels.
Carcinoembryonic antigen (CEA) is a non-specific serum biomarker that is elevated in various malignancies such as colorectal cancer, medullary thyroid cancer, breast cancer, mucinous ovarian cancer, etc.
This test measures the amount of CEA in the blood, and sometimes in other body fluids. CEA is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in the body. A high level of CEA can be a sign of certain types of cancers.
A CEA test measures the level of carcinoembryonic antigen (CEA) in the blood or other body fluid. As a type of tumor marker, CEA is an indicator of whether cancer is growing and spreading or diminishing with treatment. It is also known as a CEA assay, CEA blood test and carcinoembryonic antigen test.
Cancer antigen (CA) 27.29 is a monoclonal antibody to a glycoprotein (MUC1) that is present on the apical surface of normal epithelial cells.
Carcinoembryonic antigen (CEA) is a tumor marker found in the blood or in other bodily fluids that can be used to monitor treatment for certain cancers. This article explains what the CEA test is, when it can be helpful in cancer treatment, and how to interpret its results.
Your doctor can use CEA as a “marker” to learn more about your cancer. The test can often help predict whether the cancer is growing or spreading to other parts of your body.
Patients with both tumor markers increased also showed a remarkably shorter 5-year survival rate (CEA+/CA19-9+: 23%). The multivariate analysis emphasizes these results (p -value < 0.0001).
Carcinoembryonic antigen (CEA) is not normally produced in significant quantities after birth but is elevated in colorectal cancer. The aim of this review was to define the current role of CEA and how best to investigate patients with elevated CEA levels.
CEA is used as a marker for bowel cancer in particular, but may be measured where other forms of cancer are present. It has been found helpful in monitoring some patients with cancer of the rectum, lung, breast, liver, pancreas, stomach, and ovary.
