Observation or Radiation Therapy in Treating Patients With Newly Diagnosed Grade II Meningioma That Has Been Completely Removed by Surgery

This study is for adults who have recently been diagnosed with a specific type of brain tumour called 'Grade 2 meningioma.' Your tumour must have been completely removed by surgery from inside your head.

An important point is that the surgery to remove the tumour must have happened within the last six months. Doctors will need to confirm from your medical records and scans that the tumour was indeed completely removed. If you had an initial surgery and then needed another one to ensure everything was removed, that's okay, as long as the last surgery was also within the six-month timeframe.

Your age must be 18 years or older, and the study is open to both men and women. If you're unsure if you meet these requirements, it's always best to discuss it with your doctor.

If you decide to join this study, you'll be randomly assigned to one of two groups, like flipping a coin. You won't get to choose which group you're in. One group will be 'observation,' meaning doctors will regularly monitor you with scans. The other group will receive radiation therapy, which involves daily treatments, usually five days a week, for about six to seven weeks. Throughout the study, both groups will have regular MRI brain scans and blood tests.

After your main treatment (either observation or radiation therapy) is complete, you'll have follow-up appointments. These will be quite frequent at first (at 3, 6, and 12 months), then every six months for the next two years, and finally once a year for up to 10 years. During these follow-ups, doctors will check how you're doing, look for any signs of the tumour returning, and ask about your quality of life. You'll also have the right to withdraw from the study at any time.
