This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at past patient records, so this is not proof from a real trial.
The short version
One pattern on the first MRI may point to who needs radiation along with chemo.
What was studied. Doctors looked back at records for fifty people with lymphoma in the brain. They checked each person's first MRI for a bright lining around the brain's fluid spaces.
What they found. People with that bright lining had a higher risk of dying and of the cancer growing back. Among them, those who got chemo plus radiation stayed cancer free for 33.5 months, compared with 3.0 months for chemo alone. They also lived 39.8 months, compared with 13.4 months.
What this means, and what it doesn't
What it could mean: If your first MRI shows this pattern, it may be a warning sign. It may also be a reason to ask your doctor about radiation along with chemo. Your own care still depends on your case.
What it doesn't mean: This does not mean the scan finding settles what will happen to you. It was a look back at old records from one hospital, not a planned trial. No one was assigned to a treatment on purpose, so the groups may have differed in other ways. It does not show that radiation is right for everyone with this finding. It is not a cure.
