This was done on cells in a lab, not in people. It is a very early step.
This was lab work on stored tumor samples, not a treatment.
The short version
This study tested a lab technique on saved tumor tissue, not a new treatment.
What was studied. Researchers looked at tissue from ten 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 tumors. Five tumors had extra copies of a gene called EGFR. Five did not. The team measured the proteins inside each sample.
What they found. The method worked on all ten stored samples. Tumors with extra EGFR made more EGFR protein. The team found 443 spots on proteins that differed between the two groups. Even so, the tumors overlapped a lot with each other.
What this means, and what it doesn't
What it could mean: For now this means little for day to day care. It shows that saved tumor tissue still holds useful details. Over time, that may help doctors understand a person's tumor better.
What it doesn't mean: This does not mean a new treatment is here. No one was treated in this study. It was lab work on tissue that had already been stored. It is very early research, and it is not a cure or a promise of one.
