Kaplan-Meier analysis of GBM patient survival partitioned by age and predictive expression signature. A. GBM patients younger than age 40 partitioned by PN status versus non-PN status. Younger patients with PN GBMs survive longer than fellow younger patients with non-PN GBMs. PN GBM patients age < 40 survival (mean = 3.0 years, median = 2.9 years) vs. non-PN GBM patients age < 40 survival (mean = 1.4 years, median = 0.8 years). B. GBM patients older than age 40 partitioned by PN status versus non-PN status. Older patients with PN GBMs survive longer than fellow older patients with non-PN GBMs. PN GBM patients age > 40 survival (mean = 1.9 years, median = 1.1 years) vs. non-PN GBM patients age > 40 survival (mean = 1.2 years, median = 0.9 years).
