This was tested in people. That is the most reliable kind of research we share.
This used computer models of real patients' plans, and it did not test a new treatment.
The short version
Two common ways of giving brain radiation hit the blood a bit differently, but neither one was shown to be better.
What was studied. Researchers looked back at the radiation plans of 28 people with 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 used a computer model to see how much of the blood passing through the brain two common radiation methods would reach.
What they found. One method reached more of the blood than the other in 24 of 28 patients. After three treatments, it reached about 90% of these blood cells, compared with 77% for the other method. The loss of blood cells was close for both, at 13.9% and 12.8%, and was higher when the treated area was larger.
What this means, and what it doesn't
What it could mean: Both radiation methods seem to affect these blood cells in a similar way. This may help doctors think about how radiation plans affect the blood cells that help fight disease.
What it doesn't mean: This does not mean one method is better or safer for you. It was a computer model built from past patient plans, not a test of how patients did. It does not change care today, and it is not a cure.
