One of the most hopeful numbers in pediatric brain tumor care is the 75% 5-year relative survival rate for children with brain and other CNS tumors in the United States, yet outcomes can swing dramatically by subtype. Medulloblastoma has a median diagnosis age of 6 years and a 5-year overall survival of 77% in a standard-risk high-risk trial, while glioblastoma drops to about 22% over five years. We bring these results together with diagnostic imaging, emerging targeted and CAR-T approaches, and market and trial signals to show where progress is steady and where it still feels out of reach.

- MRI is the primary diagnostic imaging modality for pediatric brain tumors
- Neurofibromatosis type 2 (NF2) is associated with meningioma and ependymoma syndromes; germline NF2 mutations account for a subset of ependymoma cases

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
