The short version

Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary has returned.
Who this trial is for. This trial is for people whose glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary has come back after earlier treatment. It is testing the TheraSphere GBM device to see if using it is safe and whether the procedure can be done the way it is meant to be done.
Where it stands. This trial has not reported results. It is measuring safety and whether the treatment can be carried out as planned. Those answers are not in yet.
What this means, and what it doesn't
What it could mean: For now, this is a study, not a treatment your own doctor can give you. If your glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary has come back, you could ask your care team whether a trial like this one is worth looking into for you.
What it doesn't mean: This does not mean the treatment works. A trial is a test, and the answers are not known yet. Being in a trial is not a guarantee that you will be helped. This is not a promise of a cure, and it is not proven care.
