MGMT and glioblastoma: Although older age at diagnosis is a well-established risk factor for poorer outcome and shorter overall survival in patients with GBM, patients with F3T3-positive GBMs in this study lived slightly longer than those without F3T3 fusions (26.7 vs. 18.5 months, p = 0.07), a difference that persisted after adjustment for potential confounders including age, sex, race, and MGMT status.
