This was tested in people. That is the most reliable kind of research we share.
This is a write up of one person's tumor tests, not a treatment being tested.
The short version
Doctors found a gene change in one man's brain tumor that had never been reported before.
What was studied. Doctors wrote up the case of one man, age 73, with a brain tumor called 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. They ran deep gene tests on the tumor tissue.
What they found. The tests showed two genes, EWSR1 and RAD51B, joined together in a new way. The doctors say this is the first time this pairing has been reported in 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. Other tests on the tumor still pointed to glioblastoma, IDH-wildtype, and also found changes in the MGMT promoter methylation: MGMT is a gene whose protein repairs damage to a tumor's DNA. Methylation turns it down. Your report says how much, and your team uses that when they choose chemotherapy. The line between high and low is not settled. See the glossary and PTEN genes.
What this means, and what it doesn't
What it could mean: Careful gene testing can turn up rare changes in a tumor. Here it helped doctors feel sure about the diagnosis. It is one reason doctors may run a full set of gene tests on a brain tumor.
What it doesn't mean: This is a report about one person, not a study of a treatment. Doctors say they do not yet know what this gene change does. It does not point to a new drug, and it does not change care today. It is not a cure.
