This was tested in people. That is the most reliable kind of research we share.
Repeat surgery is already something doctors do today for some patients.
The short version
When a glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary comes back, a second surgery may add more months of life for some people.
What was studied. Doctors looked back at records of 1304 patients whose glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary came back, treated between 2010 and 2018. They closely matched 140 patients who had a second surgery with 140 who did not.
What they found. The group that had a second surgery lived 521 days longer. They also gained 9.6 months of life in good health. Gains were smaller and less certain in the glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary group, 3.5 months and 218 days.
What this means, and what it doesn't
What it could mean: A second surgery may help some people, but not everyone. Doctors can look at your health and scans first to see if you may benefit. It is a fair question to ask your care team.
What it doesn't mean: This does not mean a second surgery is right for every person. It is not a cure, and it was not a trial. Doctors only looked back at old records, so other things could explain the results. The benefit looked weaker and less sure for glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary. Surgery also carries real risks.
