Pancreatic cancer

What is CA 19-9?

The CA 19-9 is a tumor marker that is used along with other tests and procedures to help detect and diagnose cancer, monitor a person's response to treatment, and detect a recurrence. CA 19-9 levels are high in 70% to 90% of people with advanced pancreatic cancer, but high levels can also be due to a number of other conditions such as colorectal cancer, lung cancer, gallbladder cancer, gallstones, pancreatitis, cystic fibrosis and liver disease. Healthy people often have small amounts of CA 19-9 as well.

If CA 19-9 is elevated, your doctor may recommend additional tests, such as an CT scan, ultrasound, MRI, ERCP, and/or a biopsy.

Can CA 19-9 be consistently increased in a person without cancer?

Yes. Cases of people with long lasting high levels of CA 19-9 with no evidence of cancer have been described in the medical literature. One common cause of highly elevated CA 19-9, not due to cancer, is cholestasis. Click here to visit MedlinePlus and learn more about cholestasis. Other reported cases have been due to interstitial pulmonary fibrosis, diabetes, endometriosis, H. pylori infection, and ruptured epidermoid cyst. Medications may also play a role in elevated CA 19-9. People with high levels of CA 19-9 and no signs of cancer, benefit from careful monitoring. Talk with your doctor about setting a plan for follow-up.
