- These tools are intended to assist healthcare professionals (HCPs) by providing individualized risk estimates to help support treatment decisions for patients with HR+, HER2−, node-negative and node-positive (1-3 positive nodes), early-stage invasive breast cancer diagnosis. They are not medical devices and have not been reviewed, cleared, or approved by the FDA. The tools, used at the physician’s discretion, offer individualized risk estimates based on clinical trial data summarized in published literature, providing information that supports clinical decision-making but does not replace or direct the HCP's judgment.
The tools integrate clinical and pathological information with Oncotype DX Breast Recurrence Score® test results to generate individualized risk estimates intended to help inform, but not determine, clinical decisions. They are provided exclusively to HCPs as part of the laboratory-developed test (LDT) offering. HCPs must independently review and interpret the information, considering patient-specific factors, clinical guidelines, and their own professional judgment before making any medical decisions.
