New England Journal of Medicine Publishes MINDACT Trial Results Proving the Clinical Utility of MammaPrint® in Assisting Physicians to Identify Early-Stage Breast Cancer Patients who can Safely 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 reclassified as Low Risk by MammaPrint® and MINDACT shows could possibly … Continued
