Study Overview:
This study is for patients with a type of brain tumor called grade II meningioma, which has been completely removed by surgery. The goal is to see if adding radiation therapy after surgery helps patients live longer without the tumor coming back. Radiation therapy uses powerful x-rays to kill any leftover tumor cells.
In this study, patients are divided into two groups. One group will only be observed, meaning doctors will watch them closely without any additional treatment. The other group will receive radiation therapy five days a week for about seven weeks.
Key Considerations:
- The study lasts many years, with follow-ups at different intervals for up to 10 years.
- Patients must have had the tumor completely removed and meet specific medical criteria.
- Participants may have to undergo numerous MRI scans and other assessments.
To join, patients need to have a confirmed diagnosis and a good health status. This study helps doctors understand if radiation therapy should be standard after surgery for grade II meningioma.
