This was tested in people. That is the most reliable kind of research we share.
It was tried in people, but it is not proven care yet.
The short version
Doctors used MRI scans during treatment to keep the radiation aimed well.
What was studied. The study included 73 people with high grade glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary. They had standard radiation along with the drug temozolomide: A chemotherapy taken as a capsule, used for some brain tumors. Your team checks your blood counts while you are on it. See the glossary. They had MRI scans before radiation, after 10 sessions, and after 20 sessions.
What they found. The tumor and the area around it changed shape during treatment. The biggest changes showed up after 10 sessions. Redoing the plan gave better radiation dose to the target area. It also lowered the dose to healthy organs nearby.
What this means, and what it doesn't
What it could mean: This may help doctors pick a good time to redo a radiation plan. The study suggests a check after 10 sessions. It may matter most for people with tumors smaller than 5 cm and a certain gene type.
What it doesn't mean: This is not a new drug and not a cure. It is one study, and its main goal was to measure scan and dose changes. It does not show that people live longer. There are still no clear rules for who should get this or when. It is not standard care at every center. Ask your radiation doctor what your center does.
