About the Oncotype DX Breast Recurrence Score® Test

From the moment breast cancer is diagnosed, your patient depends on you to recommend the best course of action. But, it is important to remember that no two breast cancer patients—or their tumors—are alike.

The Oncotype DX Breast Recurrence Score test provides a genomic-based, comprehensive, individualized risk assessment for early-stage invasive breast cancer in adjuvant and neoadjuvant settings. The test provides valuable information you can use to personalize a treatment plan specifically for each patient’s situation—including risk of distant recurrence, the benefit from chemotherapy and whether your patient can be treated effectively with hormonal therapy alone.1-6

Incorporated in
ASCO®, NCCN®, and ESMO Guidelines, St. Gallen Consensus, and NICE Diagnostic Guidance*

Included in all major breast cancer treatment guidelines

The Breast Recurrence Score test is recognized as the standard of care. It’s included in clinical guidelines from organizations such as the American Society of Clinical Oncology (ASCO®), the National Comprehensive Cancer Network (NCCN®), the St. Gallen Consensus panel, the National Institute for Health Care Excellence (NICE), the European Society for Medical Oncology (ESMO) and the German Association of Gynecological Oncology (AGO).7-12*

How it works

The Breast Recurrence Score test is proven to predict the likely benefit of chemotherapy2, 3—as well as the risk of distant recurrence1, 4—for patients who are newly diagnosed with early-stage invasive breast cancer. Eligible patients are diagnosed with early stage, ER+, HER2- breast cancer with either node-negative or node-positive disease. The test uses RT-PCR to measure the expression of 21 genes: 16 cancer-related genes and five reference genes - in a tumor sample after it has been removed by surgery or biopsy.

The Oncotype DX Breast Recurrence Score: Predictive and Prognostic Results you can Count on

By testing every eligible patient after surgery, but before you discuss her treatment plan, you can make recommendations with increased insight and confidence.

TAILORx: The largest, independently-led, randomized adjuvant breast cancer treatment trial

TAILORx trial demonstrated the precision with which the Oncotype DX Breast Recurrence Score test allows us to predict with confidence the patients who will benefit from chemotherapy and who will not. Knowing the Oncotype DX Breast Recurrence Score can guide you and your patient to the right systemic adjuvant treatment decision.

The Breast Recurrence Score report: Informative for both clinicians and patients

The results are presented as a quantitative score, based on a continuous scale from 0-100. The score reflects individual tumor biology—the higher the score, the higher the risk of distant recurrence and the higher the likelihood of chemotherapy benefit are for that patient.2 The Breast Recurrence Score result can serve as a reference point for all members of the treatment team and can make discussing treatment options with your patients easier and more efficient.

The Breast Recurrence Score report also provides a quantitative ER score by RT-PCR to help assess the magnitude of hormonal therapy benefit13 and other supporting information (such as PR and HER2 scores). The test can provide insight into specific tumor biology, risk assessment and can inform treatment options.
