- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors only looked back at people already treated, so nothing new was proven here.
The short version
Doctors looked back at 154 patients to learn who lived longer with this treatment.
What was studied. Doctors reviewed the records of 154 people with lung cancer that had spread to the lining of the brain and spine. Each one had a small port placed under the scalp. Chemo was then sent through it into the spinal fluid once a week, for 4 to 6 weeks.
What they found. Half the patients lived longer than 331 days, and half lived less. Almost all had one common type of lung cancer, and 76.7% had a change in a gene called EGFR. Two things helped predict how long people lived: how well they could handle daily activities, and the pressure of the fluid around the brain.
What this means, and what it doesn't
What it could mean: This kind of treatment is already used in some hospitals for this problem. The study may help doctors get a better sense of what to expect for one person. That can make it easier for you and your doctor to plan care together.
What it doesn't mean: This was not a test of a new drug. Doctors only looked back at charts of people already treated. No one was compared to a group that did not get this chemo. So we cannot say the chemo alone caused these results. The scoring tool they built is early and needs more testing before wide use. This is not a cure, and one person's outcome can be very different from the numbers here.
