Fig. 2From: Prognostic value of subventricular zone involvement in relation to tumor volumes defined by fused MRI and O-(2-[18F]fluoroethyl)-L-tyrosine (FET) PET imaging in glioblastoma multiformea Kaplan-Meier plots of survival versus KPS showing significantly worse survival in patients with KPS values greater than the median (median OS 15âmonths versus 7âmonths). b Kaplan-Meier plots showing that greater KPS was associated with worse PFS (median PFS 8 versus 4). c and d PET-T1-Gad volume was associated with worse survival but not PFS, respectivelyBack to article page
