Abstract 4258: Preliminarily results of the Oncohabitats Study: A multicentre validation of overall survival (OS) estimation of patients with gliobla…

Abstract We report preliminarily results of an international retrospective study (NCT03439332) analyzing the prognostic value of the early assessment of vascular architecture of glioblastoma (GBM). The initial cohort included 300 pts treated at 7 European hospitals. Multiparametric images were processed by Oncohabitats (www.oncohabitats.upv.es) to obtain the cerebral blood volume (CBV) and cerebral blood flow (CBF) from 4 automatically delimited regions of interest (ROIs): high angiogenic tumor (HAT), low angiogenic tumor (LAT), infiltrating peripherial edema (IPE), and vasogenic peripherial edema (VPE). Uniparametric Cox regression models and Kaplan-Meier analysis were developed to test pr…
Robust association between vascular habitats and patient prognosis in glioblastoma: An international multicenter study
2019
Background Glioblastoma (GBM) is the most aggressive primary brain tumor, characterized by a heterogeneous and abnormal vascularity. Subtypes of vascular habitats within the tumor and edema can be distinguished: high angiogenic tumor (HAT), low angiogenic tumor (LAT), infiltrated peripheral edema (IPE), and vasogenic peripheral edema (VPE). Purpose To validate the association between hemodynamic markers from vascular habitats and overall survival (OS) in glioblastoma patients, considering the intercenter variability of acquisition protocols. Study Type Multicenter retrospective study. Population In all, 184 glioblastoma patients from seven European centers participating in the NCT03439332 c…
