This was tested in people. That is the most reliable kind of research we share.
This looked back at stored tumor samples from people, and it is not a treatment.
The short version
The shape of the center part of tumor cells may give doctors a clue about outlook.
What was studied. Researchers measured the shape of tumor cell centers on routine stained tissue slides. They used two large stored sets of glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary samples, plus gene and protein data from the same tumors.
What they found. People whose tumor cell centers were more oval tended to live longer. The same link showed up in both sets of samples. No single gene explained the shape, but groups of genes tied to cell change, swelling, and stress were linked to it.
What this means, and what it doesn't
What it could mean: These stained slides are already made for most people with glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary. So one day this shape measure might help doctors judge outlook without a new test or another biopsy.
What it doesn't mean: This is not a treatment, and it is not a cure. Researchers looked back at stored tumor samples, not at new patients. Nothing here changes your care today. Much more work is needed before a doctor could use this.
