- Review
- Tested in people
This was done on cells in a lab, not in people. It is a very early step.
This was done in lab cells and with patient data, not tested as a treatment in people.
The short version
Scientists looked for reasons radiation stops working for some 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.
What was studied. Researchers made a score to measure how well tumor cells resist radiation. They tested it on lab-grown brain tumor cells and on tumor data from patients.
What they found. The score could show how tumor cells and patients respond to radiation. Cells at the outer edge of the tumor resisted radiation more than cells in the center. Immune cells called macrophages were linked to more resistance, and a signal they release, called IL1B, helped tumor cells resist radiation.
What this means, and what it doesn't
What it could mean: This may help explain why 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 sometimes comes back after radiation. In the future, it could point to new treatments to use alongside radiation.
What it doesn't mean: This is early lab research. It does not offer a new treatment you can get today. It does not change how radiation is given now. It is not a cure, and any new treatment based on it is still far away.
