This was tested in people. That is the most reliable kind of research we share.
Both radiation plans are already used in everyday care today.
The short version
People with glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary were more likely to finish radiation when it took fewer weeks.
What was studied. Researchers looked at records from 43,696 people with glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary. All had radiation after surgery between 2018 and 2022. The team compared a shorter radiation plan with the usual longer one, before, during, and after COVID.
What they found. Use of the shorter plan went up a little, from 10.1% before COVID to 11.9% after. People on the shorter plan finished treatment far more often, 79.3% to 82%, than people on the longer plan, 33.7% to 37.6%. Overall, the share of people who finished radiation rose from 38.9% to 43.6%.
What this means, and what it doesn't
What it could mean: A shorter radiation plan may make it easier to get through treatment. It means fewer trips to the clinic. If travel or time is hard for you, ask your care team if a shorter plan could fit you.
What it doesn't mean: This study looked back at records. It did not test which plan helps people live longer. It does not prove the shorter plan is right for everyone. The researchers say more study is needed on long-term results. This is not a cure.
