ConfirmMDx for Prostate Cancer

Are You at Risk for Prostate Cancer after a Negative Biopsy?

A Prostate Biopsy Samples Less Than 1% of the Entire Gland1

Research has shown that up to 30% of men with a negative/benign prostate biopsy result actually do have prostate cancer. The disease is very difficult to diagnose, because a prostate biopsy samples less than 1% of your entire prostate gland. This means that prostate cancer might be present in one or more small tumors located in areas the biopsy needle did not sample.1,2

If you and your urologist have concerns about your risk for undetected prostate cancer, ConfirmMDx can provide more information after a negative biopsy by helping detect, at the molecular level, cancerous tumors that may be present anywhere in your prostate gland.

Is ConfirmMDx Right for You?

For Many Patients, Yes. The Test Results Provide Actionable Information to You and Your Urologist.

You are eligible to have ConfirmMDx testing if you have received any of the following prostate biopsy results within a prior 30 month timeframe:

  • Negative/benign
  • HGPIN (high-grade prostatic intraepithelial neoplasia)
  • Atypia (atypical glands suspicious for malignancy)
  • ASAP (atypical small acinar proliferation)
  • PIA (proliferative inflammatory atrophy, or lesion)

ConfirmMDx provides actionable information that can help your urologist determine if you are at risk for prostate cancer and determine your need for a repeat biopsy.

What if Your Urologist Has Not Yet Recommended the Test for You? 

Patients who wish to participate actively in their own healthcare decisions often inquire about newer diagnostic tests. If you are eligible, as described above, ConfirmMDx, is well worth discussing with your physician.  

More and more urologists across the US are becoming aware of the clinical benefits of ConfirmMDx, including earlier treatment and improved patient outcomes and are rapidly adopting the test for routine patient care. As of 2018, more than 100,000 ConfirmMDx tests have been performed. ConfirmMDx is included in the guidelines of the National Comprehensive Cancer Network (NCCN), an alliance of 23 world-leading cancer centers from across the US, and the European Association of Urology (EAU). In addition, Medicare covers the cost of the test.

How does ConfirmMDx Work? 

ConfirmMDx is Performed on the Tissue from Your Prior Biopsy.

ConfirmMDx for Prostate Cancer works at the DNA level to help identify undetected cancers. The test is able to detect abnormal DNA changes associated with the presence of prostate cancer. These changes cannot be seen by the standard microscopic evaluation traditionally used by pathologists to screen prostate biopsies.

The Epigenetic Field Effect

ConfirmMDx detects a field effect associated with the presence of cancer.  This halo around a tumor can be detected on a molecular level in prostate cells despite having a normal appearance under the microscope.
