- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at people who already had surgery, so nothing new was tested.
The short version
After pituitary tumor surgery, people with larger tumors more often had low hormone levels.
What was studied. Doctors looked back at records of 124 people with pituitary tumors. All had surgery through the nose at one hospital.
What they found. After surgery, 38 people had low hormone levels and 86 did not. Those with hormone problems were older and had larger tumors. Taking out the whole tumor was linked to a lower risk.
What this means, and what it doesn't
What it could mean: Tumor size and how much of it comes out may affect hormones after surgery. Your care team may plan closer hormone checks if your tumor is large.
What it doesn't mean: This is not a new treatment, and it is not a promise of a cure. Doctors only looked back at past records from one hospital. It does not show how hormones do over the long run.
