- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This was a look back at past patient records, not a test of any treatment.
The short version
People who were poorly nourished before brain tumor surgery had more problems afterward.
What was studied. Researchers looked back at records from 27,057 people who had brain tumor surgery between 2016 and 2023. They used height, weight, and a blood protein to sort people into nutrition groups.
What they found. Some groups did worse than people who were well nourished. People with extra body fat but poor nutrition, and people who were thin and poorly nourished, had more problems in the 30 days after surgery. They were also more likely to die in those 30 days. People who were heavy but well nourished did not have a higher risk of dying.
What this means, and what it doesn't
What it could mean: Nutrition before surgery may help your care team talk with you about your risk. The risk was not the same for every tumor type. A simple blood test for that protein worked about as well on its own.
What it doesn't mean: This does not mean poor nutrition caused the problems. The study only looked back at old records. It did not test any treatment, and it is not a cure. It does not show that eating differently before surgery will change how you do. These nutrition groups are not a standard test that doctors use today.
