This was tested in people. That is the most reliable kind of research we share.
This looked back at care people already had, so it is not a test of a new treatment.
The short version
People who had all of the visible tumor removed were more likely to stay free of a return.
What was studied. Doctors in Romania looked back at the records of 283 adults with diffuse gliomas. All had surgery between 2021 and 2024. The team checked how much tumor was removed and whether it came back.
What they found. At 1 year, 70.6% (132 of 187) had no return of the tumor. At 2 years, 64.2% (120 of 187) had no return. Looking at the whole group, the tumor came back in 53.7% (139 of 259). Patients who had all of the visible tumor removed were the most likely to stay free of a return.
What this means, and what it doesn't
What it could mean: This backs up what many brain surgeons already try to do. Taking out as much tumor as is safe may push back the day it returns. It is worth asking your surgeon how much of your tumor they expect to remove, and why.
What it doesn't mean: This is not a cure, and it is not a promise about any one person. The team looked back at care that had already happened. That kind of study cannot prove the surgery itself caused the better results. Sicker people and harder tumors often get less surgery, and that alone can change the numbers. The 1 and 2 year results could not be checked in 96 of 283 patients. Almost all of those had only a biopsy or partial surgery. The authors say their results show the direction only, not the exact size of the benefit. Other hospitals still need to check this.
