Brief Title: Radiotherapy for Extracranial Oligometastatic Breast Cancer
Official Title: Systemic Therapy With or Without Local Radiotherapy for Extracranial Oligometastatic Breast Cancer
Study ID: NCT04646564
Brief Summary: More and more evidence suggests that local radiotherapy can improve the outcomes for patients with oligometastatic disease. The purpose of this study is to assess the impact of radiotherapy, compared with standard systemic therapy alone, on survival, local control and toxicities in patients with extracranial oligometastatic breast cancer. Eligible patients are randomized in a 1:2 ratio between the control arm (standard systemic therapy), and the WLRT arm (standard systemic therapy + radiotherapy). Randomization will be stratified by three factors: visceral metastasis (yes vs.no), number of metastases(≤2 vs. \>2), hormone receptor(positive vs. negative). SBRT technique is preferred. During and after radiotherapy, the patients are followed and the efficacy and toxicities of radiotherapy are evaluated.
