ADAPT - Adjuvant Dynamic Marker-Adjusted Personalized Therapy Trial Optimizing Risk Assessment and Therapy Response Prediction in Early Breast Cancer

Trial for the optimization of risk assessment and therapy success prediction in patients with early breast cancer by the use of biomarkers in advance to therapy decision-making to personalize therapies.
