This was done on cells in a lab, not in people. It is a very early step.
This was a lab study on tumor samples, not something a patient can get.
The short version
Scientists tested a lab method that maps how a brain tumor's DNA has been rearranged.
What was studied. Researchers looked at 43 brain tumor samples, most of them from children. They used a lab method called optical genome mapping to see how the DNA in each tumor was rearranged.
What they found. The method found DNA rearrangements in 37 of 43 samples. The samples sorted into three patterns, based on how many changes there were and where they sat. The method also spotted joined-together genes, called gene fusions, in 24 of 30 samples. It missed them in six.
What this means, and what it doesn't
What it could mean: This is a lab tool, not a treatment. If more studies back it up, it could help doctors describe a tumor in more detail. That kind of detail can help sort out what type of tumor it is.
What it doesn't mean: This does not mean there is a new treatment. It does not mean this test is offered at your hospital. This was a small first study on tumor samples in a lab. It is an early step, and it is a long way from everyday care. It is not a cure, and it is not a promise of one.
