The Breast Recurrence Score test is the only validated genomic test for breast cancer, which provides two key answers for both lymph node-negative and node-positive early-stage breast cancer patients:
- The test predicts whether a woman will benefit from chemotherapy.
- It also provides a percent likelihood of the cancer returning after appropriate hormone therapy is taken.
The Oncotype DX Breast Recurrence Score test is incorporated in all major breast cancer treatment guidelines for both prognosis and chemotherapy benefit, including the American Society of Clinical Oncology, the National Comprehensive Cancer Network, the St. Gallen Consensus panel, the National Institute for Health Care Excellence, the European Society for Medical Oncology and the German Association of Gynecological Oncology.
