Aliases:
This biomarker is also known as:
  • CA 19.9
  • CA19-9
  • carbohydrate antigen 19-9
  • CA199
  • cancer antigen 19-9

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.

Supporting Study Data

The following studies/protocols provide evidence supporting CA19-9 indications for the Ovary…

PLCO Ovarian Phase III Validation Study

Our preliminary data indicate that the performance of CA 125 as a screening test for ovarian cancer can be improved upon by additional biomarkers. With completion of one additional validation step, we will be ready to test the performance of a consensus marker panel in a phase III validation study. Given the original aims of the PLCO trial, we believe that the PLCO represents an ideal longitudinal cohort offering specimens for phase III validation of ovarian cancer biomarkers.

SPORE/EDRN/PRE-PLCO Ovarian Phase II Validation Study

Create a new set of phase II specimens (160 cases with pre-operative bloods representing major histologic types and including 80 early-staged and 80 late-staged cases, 160 controls with benign disease, 480 general population controls, and a small set of serial Samples collected either at least 3 months apart, but not more than 6 months apart OR between 10 months apart and no more than 14 months apart in 40 healthy controls) will be used to evaluate markers identified in preliminary work. The top 5-10 markers, plus an expanded panel of Luminex markers, will comprise a “working consensus panel” for subsequent analysis in PLCO specimens.
