This was tested in people. That is the most reliable kind of research we share.
This was a look back at patient records, not a trial that proves it works.
The short version
In 68 people, chemo given into the spinal fluid caused few device problems.
What was studied. Doctors looked back at the records of 68 people whose cancer had spread to the lining of the brain and spine. Each had a small device called an Ommaya reservoir put in, and chemo was given through it into the spinal fluid.
What they found. Problems with the device happened in six patients (8.8%). Three of those were a tube placed in the wrong spot. Side effects from the chemo happened in four patients (5.9%). By the end of the study 14 patients (20.6%) had died, 10 because the cancer grew in the brain or spine.
What this means, and what it doesn't
What it could mean: Placing this device and giving chemo through it looks workable, with few problems in this group. If cancer has spread to the lining of the brain and spine, it may be one way to get chemo close to that area. It is worth asking a care team about.
What it doesn't mean: This does not show that the device helped anyone live longer. Everyone in the study got it, so there was no group to compare against. Most of these people had lung cancer and were taking targeted drugs, and those drugs may explain how long they lived. This was a look back at records from one hospital, not a planned trial. It is not a cure and it is not proof.
