NCT ID NCT07397585

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

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.
