CA19-9

Aliases:
This biomarker is also known as:
  • carbohydrate antigen 19-9,
  • cancer antigen 19-9,
  • CA19-9,

Description…

CA19-9 is a monoclonal antibody that was first discovered in the serum of patients with colon cancer. Since that time CA19-9 has been used as a tumor marker for a variety of cancers.

Overview

CA19-9 may be a molecular marker for ovarian cancer. Literature suggests that the concomitant measurement of CA19-9 with CA125 could offer some benefit in the monitoring of patients for the recurrence of ovarian carcinoma.

Performance Comment

Of the 28 ovarian cancer biomarkers tested in prediagnostic specimens, from the PLCO, CA125 remains the the single best biomarker for ovarian cancer and has its strongest signal within six months of diagnosis. CA19-9 alone was not a strong predictor.
