This was tested in people. That is the most reliable kind of research we share.
This was only tested on computer plans, not given to any patient.
The short version
Researchers used computers to test a much faster way to aim radiation at brain tumors that return.
What was studied. The team looked at people whose glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary had come back. These people had already been treated with a robotic radiation machine. Researchers redid their treatment plans on a computer using a fast proton beam called FLASH.
What they found. The FLASH plans met all the goals the doctors had set. The way the dose spread through the brain looked much like the robot plans. The FLASH plans matched the shape of the tumor a bit more closely. Each beam is given in less than 1 second.
What this means, and what it doesn't
What it could mean: This is an early sign that a faster proton treatment may be possible for tumors that come back. Shorter time on the table could be easier for someone who is tired or in pain. It may also protect more healthy brain tissue.
What it doesn't mean: This was only a planning study done on a computer. No one was treated with this method in the study. It does not show that people live longer or feel better. It is not something you can ask your doctor for today, and it is not a cure.
