This was tested in people. That is the most reliable kind of research we share.
This looked at tumor samples and patient records, not a new treatment.
The short version
New tests show this rare tumor is not the same as the tumors it was grouped with.
What was studied. Researchers studied 20 rare tumors from the sellar region, near the base of the brain. They looked at chemical tags on the tumor DNA and compared them with many other tumor types.
What they found. These tumors formed their own group, apart from other neurocytomas. Their pattern looked like tumors of hormone-making cells in other organs. Marker tests fit nerve and hormone cells. One marker was found in 8 of 8 cases, and another in 5 of 5. Gene testing in 5 cases found no repeated gene changes.
What this means, and what it doesn't
What it could mean: Doctors may be able to name this tumor more exactly. A clear name can help guide care and future study. Of the patients followed, 13 had their outcomes checked. None died from the tumor during that time. The follow-up time was short.
What it doesn't mean: This is not a new treatment, and it is not a cure. It does not promise one. The work was done on tumor samples and patient records. It does not change the care you can get today. Bigger studies with longer follow-up are still needed.
