This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at past records at one hospital, so this is not proven yet.
The short version
People who had a second brain surgery right after radiation lived longer in this study.
What was studied. Doctors looked back at records of 174 adults with glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary at one hospital. All had the usual radiation and chemo. Some then had a second surgery before their next round of chemo.
What they found. After radiation, spots that light up on scans were found in 118 of 174 patients. 17 of those patients had a second surgery, and they lived longer. Doctors removed the whole spot in 5 patients and almost all of it in 4 more. Living tumor was found in every sample they took.
What this means, and what it doesn't
What it could mean: For a few people, a second surgery soon after radiation may be worth asking about. It can also show whether living tumor is still there. Your care team can say if surgery is safe in your case. Two patients got weaker after surgery, and two had wound problems.
What it doesn't mean: This does not mean surgery after radiation is a cure. Doctors only looked back at old records at one hospital. They did not run a trial that compared groups fairly. Just 17 people had this surgery, so the numbers are small. The patients picked for surgery may have been doing better to start with. Brain surgery carries real risk, and it is not right for everyone.
