Role of Metastases Directed Radiotherapy in Addition to Standard of Care Systemic Treatment in the Management of Extracranial Oligometastatic Breast Cancer
This is a phase III randomized study evaluating the benefit from adding metastases directed therapy and locoregional treatment of the primary in breast cancer patients diagnosed with de novo oligometastatic disease patients will be randomized to receive the standard of care (SOC) treatment vs. systemic treatment + Stereotactic Ablative Radiation Therapy. Responders will be randomized to either undergo loco-regional management of the primary tumor or not
