Summary

This trial is testing whether adding SBRT to the usual cancer drug therapy can help people with oligometastatic breast cancer by preventing the cancer from worsening in other metastatic sites or spreading.

Who is the study for?
This trial is for adults with metastatic breast cancer who've had a good response to drug therapy for at least 6 months. It's open to those with certain hormone receptor statuses, able to consent, and have only one site of disease progression visible on a scan. Pregnant individuals, those with previous radiation at the target site or brain involvement, and serious medical conditions that conflict with radiation are excluded.Check my eligibility
What is being tested?
The study tests adding Stereotactic Body Radiation Therapy (SBRT) targeting just one metastatic site alongside ongoing usual drug therapy in people with oligometastatic breast cancer. The goal is to see if this precise radiation can prevent the cancer from getting worse elsewhere.See study design
What are the potential side effects?
Potential side effects of SBRT may include skin reactions, fatigue, pain at the treatment site, and rarely more severe issues like damage to nearby organs or tissues depending on where the treatment is aimed.

Experimental Treatment
Group I: Participants with oligometastatic breast cancerExperimental Treatment1 Intervention
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.
