Also known as: AFP and AFP-L3%, AlphaFetoprotein AFP and AFPL3

AFP

AFP is used as a tumor marker to help detect and diagnose cancers of the liver, testes, and ovaries. Though the test is often ordered to monitor people with chronic liver diseases such as cirrhosis, chronic hepatitis B or hepatitis C because they have an increased lifetime risk of developing liver cancer. If a person has been diagnosed with hepatocellular carcinoma or another form of AFP-producing cancer, an AFP test may be ordered periodically to help monitor the person's response to therapy and to monitor for cancer recurrence.

AFP-L3

An AFP-L3% is sometimes also ordered to compare the amount of the AFP variant called AFP-L3 to the total amount of AFP. The test is used to help evaluate the risk of developing hepatocellular carcinoma, especially in those with chronic liver disease, and also to evaluate response of hepatocellular carcinoma to treatment.

Also known as: CA 125 Tumor Marker, CA-125, Cancer Antigen 125, OC125, Ovarian Antigen

Ca 125

The Cancer Antigen 125 (CA-125) test measures the amount of CA-125 in the blood. CA-125 is a protein that is present on the surface of most, but not all, ovarian cancer cells. This makes the test useful as a tumor marker in specific circumstances. Significantly elevated concentrations of CA-125 may be present in the blood of a woman who has ovarian cancer. Small quantities of CA-125 are produced by normal tissues throughout the body and by some other cancers. Levels in the blood may be moderately elevated with a variety of non-cancerous conditions, including menstruation, pregnancy, and pelvic inflammatory disease.

Also known as: CA 153, CA-Breast, Cancer Antigen 15-3, Cancer Antigen-Breast

Ca 15-3

Cancer antigen 15-3 (CA 15-3) is a protein that is produced by normal breast cells. In many people with cancerous breast tumors, there is an increased production of CA 15-3 and the related cancer antigen 27.29. CA 15-3 does not cause cancer; rather, it is shed by the tumor cells and enters the bloodstream, making it useful as a tumor marker to follow the course of the cancer. CA 15-3 is elevated in only about 10% of women with early localized breast cancer but is elevated in about 80% of those with metastatic breast cancer. CA 15-3 may also be elevated in healthy people and in individuals with other cancers (e.g., colon, lung, pancreas, ovary, or prostate malignancies) or certain conditions (e.g., cirrhosis, hepatitis, and benign breast disease).

Also known as: CA 199, Carbohydrate Antigen 19-9

Ca 19-9

Cancer antigen 19-9 (CA 19-9) is a protein that exists on the surface of certain cancer cells. CA 19-9 does not cause cancer; rather, it is shed by the tumor cells, making it useful as a tumor marker to follow the course of the cancer. CA 19-9 is elevated in 70% to 95% of people with advanced pancreatic cancer, but it may also be elevated in other cancers, conditions, and diseases such as colorectal cancer, lung cancer, gallbladder cancer, bile duct obstruction (e.g., gallstones), pancreatitis, cystic fibrosis, and liver disease. Small amounts of CA 19-9 are present in the blood of healthy people.

Also known as: CA 2729, Cancer Ag 27-29

Ca 27.29
