This was tested in people. That is the most reliable kind of research we share.
This looked back at records of people already treated, so it is not a new treatment you can ask for.
The short version
In this study, people still taking steroids 6 months after their glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary diagnosis lived a shorter time.
What was studied. Researchers looked back at the records of 223 people diagnosed with glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary between 2010 and 2014 in one region of Switzerland. They checked who took steroid medicine, when they took it, and how long they lived.
What they found. Almost everyone took steroids at some point in the first year after diagnosis. That was 201 patients, or 95%. Around the time of surgery, 151 patients, 69%, took them, and 92 patients, 61%, took them in the first 3 months. People who were still on steroids at the 6 month mark lived a shorter time, even after the team accounted for other things known to affect survival.
What this means, and what it doesn't
What it could mean: Steroids are still widely used, and they help many people with swelling and symptoms. This study suggests it is worth using the lowest dose for the shortest time that is safe. If you are on steroids, it is a fair thing to ask your care team about. Any change to your steroid dose is a decision for your doctor, not something to do on your own.
What it doesn't mean: This does not mean steroids shortened anyone's life. The researchers only looked back at old records. They did not test a new treatment or compare groups on purpose. They also point out a big catch. Steroids are often given because a tumor is causing symptoms, and a tumor causing symptoms is itself a sign of a harder course. So the steroids and the worse outcome may both come from the same underlying problem. The researchers say they do not fully understand what is going on in the body here. This is not a new treatment, and it is not a promise of a cure.
