- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at what happened to real patients, so it is guidance for a decision, not a new treatment.
The short version
Most people in this study stayed at the same level of daily function 30 days after a second brain surgery.
What was studied. Doctors at one hospital looked back at the records of 166 adults with glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary. All had radiation first. Later, scans suggested the tumor was growing, so each had a second operation, either a biopsy or surgery to remove tissue.
What they found. 37 of the 166 patients, or 22.3%, could do less for themselves 30 days after the operation. 127 patients, or 76.5%, stayed about the same, and 2 patients, or 1.2%, got better. Biopsies and removals had similar rates of decline. Patients taking steroids before the operation were more likely to decline, and patients who declined lived a shorter time, 4 months compared with 11 months.
What this means, and what it doesn't
What it could mean: If you and your doctor are weighing a second operation, this gives some sense of what can happen. Most people in this group held steady. Some did get worse. Steroid use before surgery may be worth asking your team about when you talk over the decision.
What it doesn't mean: This does not mean a second operation is safe for everyone. It is not a cure, and it is not a new treatment. Doctors only looked back at old records from one hospital. That kind of study cannot prove what caused a patient to decline. Your own case may be different, so talk it through with your care team.
