This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at past patient records, and a proper trial is still only planned.
The short version
A lower dose of radiation, with no chemotherapy, kept most of these tumors under control.
What was studied. Doctors looked back at records for 139 people with a brain tumor called pure germinoma. Everyone was treated with radiation alone, with no chemotherapy.
What they found. Patients were followed for about 102 months. At 5 years, 90.0% had no sign the tumor came back or grew, and at 10 years it was 88.4%. Almost everyone was still alive, 100.0% at 5 years and 98.4% at 10 years, and no severe radiation side effects were seen.
What this means, and what it doesn't
What it could mean: A lower radiation dose may be enough to control this tumor. Less radiation may mean fewer lasting side effects. If this tumor affects you or someone you love, you can ask the care team about the dose they plan to use.
What it doesn't mean: This is not a promise of a cure. Doctors looked back at records of past patients. They did not run a planned trial that compared doses head to head. The results may not fit every person. The study team says a new trial is planned to test this properly. Nothing here changes what your own doctor can offer you today.
