- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at people already treated this way, and it has not been tested against other treatments in a trial.
The short version
Doctors looked at how 29 people did after a focused radiation treatment that aims at many brain tumors in one setup.
What was studied. Doctors reviewed the records of 29 patients who had 130 tumors that spread to the brain. All were treated between December 2018 and March 2023 with a system that aims focused radiation at many spots from a single center point.
What they found. At 12 months, 48.5% of the people were still alive. The treated tumors grew back in 14.4% of the spots by 12 months, and 43.6% of people had their brain tumors held in check at that point. Side effects were few. 4 people had a headache, one had nausea, and one had hair loss. 9 people had damaged patches of brain tissue in 13 spots, and none of them had symptoms from it.
What this means, and what it doesn't
What it could mean: For people with several tumors in the brain, this may be one way to treat many spots in a single setup. In this group, serious side effects were not common. Your own doctor can tell you if this kind of radiation is an option for you.
What it doesn't mean: This is not a cure, and it is not a promise about how long anyone will live. The doctors simply looked back at records from one group of 29 people. This was not a trial that compared this setup against other treatments. The study authors say more study is needed before this is settled.
