This was done on cells in a lab, not in people. It is a very early step.
This was only done in cells in a dish and in mice.
The short version
Scientists made a new marker that may help show 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 on scans.
What was studied. Researchers tested a new tagged marker on four kinds of 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 cells. They also scanned mice to see where the marker went in the body.
What they found. The marker stuck to the cells and got inside them. At 30 minutes, it stuck to 8.0%, 3.9%, 6.0%, and 8.6% of the four cell types. It did not change cell growth or cell death, but it did slow movement in two cell types. In mice, it left through the kidneys and reached the brain within the first few minutes.
What this means, and what it doesn't
What it could mean: This may one day help doctors see 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 more clearly on scans. It could also point to new treatment ideas to test later.
What it doesn't mean: This does not mean a new scan or drug is ready for you. The work was done only on cells in a dish and in mice. No person was scanned or treated with it in this study. It is not a treatment, and it is not a cure. It is still far from everyday care.
