Oligometastatic Breast Carcinoma, Breast Cancer, Metastatic Breast Cancer
About this trial
This is an interventional treatment trial for Oligometastatic Breast Carcinoma focused on measuring oligometastatic breast cancer, breast cancer, ER+ Breast Cancer, HER2+ Breast Cancer, Metastatic Breast Cancer, Stereotactic Body Radiation Therapy, 22-259, Memorial Sloan Kettering Cancer Center
Eligibility Criteria
Inclusion Criteria:

Metastatic breast cancer, biopsy proven
- ER+/HER2-, defined as >5% ER+ staining
- HER2+ (regardless of ER status), including HER2-low and high expressors
- History of at least 6 months, sustained response to systemic therapy (clinically or radiographically defined as complete or stable response without progression)

- Consented to 12-245
- ECOG performance status 0-1
Exclusion Criteria:

Arms of the Study
Arm 1
Experimental
Participants with oligometastatic breast cancer
Participants with oligometastatic breast cancer with isolated progression after sustained (>=6 month) response to systemic therapy. Participants will receive image guided, SBRT to the progressive lesion identified on imaging. Participants will be maintained on their existing line of systemic therapy. Systemic therapy will be held during days of radiation and resume following completion of radiation.
