New England Journal of Medicine Publishes MINDACT Trial Results Establishing the Clinical Utility of MammaPrint® in Assisting Physicians to Identify Early-Stage Breast Cancer Patients who can Possibly Forgo Chemotherapy
- 46% of patients identified as high risk for recurrence according to clinical-pathological factors as described in the publication, and who therefore would be usual candidates for adjuvant chemotherapy, were classified as Low Risk by MammaPrint and not likely to show a significant benefit from chemotherapy.
- Other tests like the Oncotype DX® Breast Cancer Assay (21-gene assay) can result in 39% – 67% [2, 3] of patients having intermediate recurrence scores (RS 11-30), which may not provide meaningful information for physicians and their patients. MammaPrint provides binary Low Risk and High Risk results, no intermediate results.
- MammaPrint is the first and currently only genomic test with U.S. FDA 510(k) clearance for use in risk assessment for women of all ages with early stage breast cancer.

 Oncotype clinical recommendations as recurrence score (RS) 0-17 = low risk (49%), RS 18-30 = intermediate risk (39%), and RS >30 as high risk (12% (Carlson JJ 2014). However, the recently published TAILORx study4 considers RS 0-10 = low risk (16%), RS 18-25=intermediate risk (67%), and RS >25 as high risk (17%) (Sparano JA 2015)
