- Review
- Tested in people
This was done on cells in a lab, not in people. It is a very early step.
This was only lab bench work, not a test in people or animals.
The short version
This is very early lab work on chemicals that may one day help show IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary tumors on scans.
What was studied. Researchers made new versions of two chemicals that block mutant IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary, the protein made by a changed IDH1 gene. They added iodine to them and tested them in lab dishes. No people or animals were tested.
What they found. The two new iodine versions, called SK140 and SK148, blocked mutant IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary in lab tests. They blocked it better than the matching fluorine versions did. The team also tagged them with iodine-125 and both stayed stable in test liquids for 24 hours at room temperature.
What this means, and what it doesn't
What it could mean: IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary gene changes are found in some gliomas, so they matter for diagnosis and treatment. A tracer that sticks to mutant IDH1 could someday help doctors see these tumors. Right now this is only a first step at the lab bench.
What it doesn't mean: This does not mean there is a new scan or a new treatment you can get. The work was done in lab dishes, not in people or even in animals. It is at the earliest stage, many years and many tests away from everyday care. It is not a cure and not a promise of one.
