APPROX. 50
The CA 50 , also Cancer Antigen 50 ( English : Carbohydrate Antigen 50), is a glycolipid used as a tumor marker . It is an endogenous substance that is formed by tumors and is detectable in the blood. It can indicate a malignant neoplasm and serves as a follow-up examination for cancer follow-up care. It is measured through the blood serum.
The normal value is below 19 U / ml.
Indications
- Patients suspected of having tumors of the gastrointestinal tract
- Therapy / follow-up of a pancreas-CA, colon-rectum-CA, stomach-CA, endometrium-CA
Increased values are possible for:
- Endometrial cancer (cancer of the lining of the womb)
- Colorectal cancer (colon cancer)
- Gastric cancer (stomach cancer)
- Pancreatic cancer (cancer of the pancreas)
- Biliary tract cancer
- Hepatocellular carcinoma
- hepatitis
- acute pancreatitis
- Cystic fibrosis
Decreased values have no diagnostic significance.
The CA 50 provides the same information as the CA 19-9 , but has no advantages over this. According to the guidelines of the European Group on Tumor Markers (EGTM), CA 19-9 should be preferred.
