Who Should Consider Testing with Oncotype DX®?

Oncotype DX® testing is useful for many women with early-stage breast cancer, but not all. About 4 out of 10 women just diagnosed will be eligible for testing.

The American Society of Clinical Oncology (ASCO) and the National Comprehensive Cancer Network (NCCN) have guidelines for who should consider Oncotype DX testing. They generally agree that Oncotype DX testing is useful for patients with invasive breast cancer who are:

  • Newly diagnosed
  • Early stage (I or II)
  • Lymph node-negative
  • Hormone receptor-positive
  • Healthy enough to receive chemotherapy

If you don't know if you meet all of these criteria, your doctor should be able to tell you. You can also learn more about these breast cancer characteristics in Staging Breast Cancer and Breast Tumor Characteristics.

Studies are also being done to find out if Oncotype DX may be useful for patients with lymph node-positive breast cancer. It is too early to know for sure.
