This was tested in people. That is the most reliable kind of research we share.
This watched real patients getting normal care, but it is not a new treatment.
The short version
In this small study, most brain lymphoma tumors got smaller on steroids, and those patients lived longer.
What was studied. Doctors at several centers looked at people with a brain lymphoma called PCNS-LBCL. They studied 18 patients with detailed MRI volume scans, and 31 patients with a simpler 2D scan measure. All got steroid treatment after their biopsy.
What they found. In the 18-patient group, 83.3% of tumors got smaller after steroids. The tumors that shrank got smaller by about 40%. The other 16.7% grew despite steroids, growing by about 46%. Patients whose tumors shrank lived 31.4 months, compared with 3.9 months for those whose tumors grew. The dose of steroid did not seem to change the result.
What this means, and what it doesn't
What it could mean: How a tumor reacts to steroids early on may give doctors a clue about what to expect. That clue could help them plan care and talk with you about it. It does not change the treatment you get right now.
What it doesn't mean: This does not mean steroids treat this cancer or that they are a cure. Steroids shrink the tumor for a time, but the tumor can come back. This was a small study, with only 18 and 31 patients. The authors call the outlook part exploratory, and they say more studies are needed. It is a way of reading scans, not a new treatment you can ask for.
