Testing same day radiation planning and treatment for cancer that spread to the brain
Original title: Stereotactic Radiation for Growing/Changing Brain Metastases With Same-Day Radiation Planning and Treatment With Margin Reduction
How far along is this research?
This is a trial that is enrolling or has been updated. It is not a finding yet.
This is a middle stage trial, so the approach is still being tested in people.
Status: Recruiting. It is looking for patients now. Talk to your care team about whether it fits you.

The short version
This study tests giving focused brain radiation on the same day the plan is made.
Who this trial is for. This trial is for people with spots of cancer in the brain that are growing or changing. It tests focused radiation planned and given the same day, with people randomly assigned to a 1mm margin or a 0mm margin.
Where it stands. The trial is checking whether same day planning and treatment can be done and how well it works. Planning scans are repeated during treatment if more than 2-3 days have passed since the last ones. The trial has not reported results.
What this means, and what it doesn't
What it could mean: Less time between the scan and the treatment might help the radiation cover the spot better. That is the idea being tested, and the answer is not in yet. Someone who fits this picture could ask their care team about it.
What it doesn't mean: This does not mean the approach is proven. A trial is a test, not care your own doctor can give you. Being in one is not a guarantee that it will help you. It is not a promise of a cure.
