NCT ID NCT05259605
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is collecting data from 1,650 people with various brain tumors to see if the updated 2021 WHO classification system helps doctors group patients more accurately and choose better treatments. Researchers will track responses to therapy, survival, and tumor features over 5 years. The goal is to create provisional treatment guidelines for newly defined tumor types based on real-world experience.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this study could help doctors better classify brain tumors and choose more effective treatments based on the latest diagnostic criteria.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly test new therapies. Results may take years and might not change current practice immediately.
