Summary

The study is being done to determine if stereotactic ablative radiotherapy (SABR) can control tumour growth for patients with metastatic breast cancer.

Secondary objectives will be overall survival, progression-free survival and time to switch of next line of systemic therapy.

Radiation-related adverse events will be assess, with a specific focus on dermatitis, lymphedema and brachial plexopathy.

The exploratory objective is to correlate toxicities and outcomes with peripheral blood biomarkers and circulating tumor DNA to potentially help predict responses in future patients receiving combined therapy.
