Can precise radiation help when breast cancer spreads to just a few places?
NCT ID NCT07397585
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether a precise type of radiation called SBRT can help people with breast cancer that has spread to only a few spots in the body (oligometastatic). Researchers will review medical records from 300 patients to see if SBRT improves how long the cancer stays under control and how long patients live. The goal is to gather more evidence on whether this non-invasive treatment is a good option alongside standard therapies.
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 radiotherapy (SBRT)
- What this could lead to
- If this study shows SBRT helps control the cancer and extend survival, it could support using targeted radiation as a standard treatment for limited metastatic breast cancer.
- What could go wrong
- This is a retrospective study, so it looks back at past data rather than testing a new treatment in a controlled way. Results may be less reliable and not prove cause and effect.
