Kaplan-Meier survival curve for time to progression (TTP) by bilateral subventricular zone (bSVZ) dose, with TH- delineation method (excluding temporal horns): V20 Gy to bSVZ > 84% (n = 8 patients) versus ≤ 84% (n = 32 patients). Patients with V20 Gy to bSVZ greater than 84% had a statistically significant improvement in TTP (17.7 months vs 5.2 months)
