This looks across many earlier studies rather than running a new one.
This is expert opinion about what future studies should test, not a new result or a treatment you can get.
The short version
This is an expert opinion piece about future research, not a change to your treatment.
What was studied. The authors looked back at the old trials that made radiation standard care after glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary surgery. They compared those old trials to the way patients are treated today.
What they found. The old trials were done before MRI scans, before molecular testing of tumors, and before the drug temozolomide. Today some patients have all of the visible tumor removed and live three years or longer, and the old trials had no clear group like them. The authors say radiation still helps and they are not arguing against it. Their point is that no one has measured how much it helps after today's best surgery and drugs.
What this means, and what it doesn't
What it could mean: Nothing about your care changes because of this paper. Radiation after surgery is still the standard. The authors want new studies to test whether some carefully chosen patients could safely have less radiation. Those studies have not been done yet.
What it doesn't mean: This does not mean anyone should skip or reduce radiation. No new treatment was tested here, and no patients were treated in this paper. It is a discussion of what future trials should look at. It is not a promise of longer life, and it is not a cure.
