- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This kind of radiation is already given to people at some hospitals, but stronger proof about which radiation is best is still being waited on.
The short version
Most people were still alive five years after proton radiation for a slow growing brain tumor, but fewer than half were working full time.
What was studied. Doctors looked back at the records of 143 adults with slow growing brain tumors. All of them had surgery first, then a kind of radiation called proton beam radiation, at one hospital between 2016 and 2021.
What they found. About 78.21% of the whole group were alive five years later. About 80.34% went five years with no tumor growth. Fewer than half were working full time. At 12 months, 61 people (42.66%) had a full time job, and at 60 months, 59 people (41.26%) did. 4 people had a serious lasting side effect. 2 had damage to the nerve of the eye, 1 had lasting tiredness, and 1 had muscle weakness. When a larger area of the brain was treated, people were less likely to go back to full time work.
What this means, and what it doesn't
What it could mean: For many people, this treatment was followed by years without the tumor growing. But life after treatment was not the same for everyone. A lot of people in this group did not return to full time work. Treating a smaller area of the brain may help protect a person's ability to keep working. That is worth asking your team about.
What it doesn't mean: This does not mean proton radiation is a cure. It also does not mean proton radiation is better than other kinds of radiation. This was a look back at old records at one hospital. It was not a trial that compared two treatments side by side. The doctors themselves say stronger studies are still being waited on. These numbers come from one group of patients. Your own case may be different, and your care depends on your tumor and your medical team.
