This is a trial that is enrolling or has been updated. It is not a finding yet.
No phase was given for this study, so it is early work being tested in people.
Status: Recruiting. It is looking for patients now. Talk to your care team about whether it fits you.

The short version
This study is testing whether a small device called an Ommaya reservoir can be placed safely during brain tumor surgery so doctors can collect fluid from around the brain over time.
Who this trial is for. This study is for people who are already having a planned operation for a brain tumor. It tests whether an Ommaya reservoir can be put in safely during that same operation, and whether doing it that way works in practice.
Where it stands. This trial has not reported results. It is looking at how safe the placement is and whether it can be done during a planned tumor operation. The device is meant to let doctors collect the fluid around the brain and spine more than once, so they can study markers of the tumor. The answers are not in yet.
What this means, and what it doesn't
What it could mean: For now, this is a study about a way to collect fluid for research, not a treatment for the tumor itself. Someone who is already facing brain tumor surgery could ask their care team whether a study like this fits their situation.
What it doesn't mean: This does not mean the device treats a brain tumor. A trial is a test, not proven care. Joining one is not a guarantee that it will help you, and it is not a promise of a cure. Whether anyone can take part is decided by the trial team.
