Zapping a single tumor may keep breast cancer in check
NCT ID NCT05534438
First seen Jun 27, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This study tests whether giving a precise, high-dose radiation treatment called SBRT to one growing tumor can help people with metastatic breast cancer keep their disease under control. Participants continue their usual drug therapy while receiving SBRT to a single site where cancer has worsened. The goal is to see if this approach prevents cancer from spreading further or getting worse elsewhere.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Stereotactic body radiation therapy (SBRT)
- What this could lead to
- If it works, this could help people with metastatic breast cancer delay further cancer spread and stay on their current treatment longer.
- What could go wrong
- This is a small, early-phase trial with only 46 participants, so results may not apply to everyone. SBRT can cause side effects like fatigue or pain at the treated site.
