Brain and other nervous system cancers have a 10-year relative survival rate of just 7.0%. For malignant glioma, the annual probability of death in the first year after diagnosis is 2.45%. This article details specific survival benchmarks, treatment efficacy, and the market forces shaping patient outcomes.

Roughly 50% of glioblastomas harbor unmethylated MGMT promoter status (implying MGMT promoter not methylated)—measured as proportion of tumors with MGMT promoter unmethylation in pooled datasets
Interpretation
Biomarkers Interpretation
For the Biomarkers category, about 8% of glioblastomas show an IDH-wildtype profile with NOTCH1 mutations while roughly 50% have an unmethylated MGMT promoter, suggesting that biomarker patterns are split between a relatively rare NOTCH1 mutation subgroup and a much more common MGMT methylation-negative group.
