To identify subpopulations with a particularly favorable course, we assessed the prognostic potential of magnetic resonance imaging (MRI) markers before treatment onset.MethodsMRIs at baseline (before treatment onset) were analyzed for T1-hyperintense and diffusion-restricted lesions; as well as the presence of both hyperintense and diffusion-restricted (double positive) lesions. The MRI findings were correlated with overall and progression-free survival.ResultsMRI scans were evaluable in $71\%$ of the GLARIUS modified intention-to-treat population (n = 121 of 170; 88 patients in the BEV/IRI arm, and 33 patients in the TMZ control arm). Diffusion-restricted and T1 hyperintense lesions were present in $60\%$ and $65\%$ of patients in BEV/IRI arm, while $57\%$ and $63\%$ were found in the TMZ arm, respectively. Double positive lesions were found in $37\%$ of BEV/IRI patients and in $39\%$ of TMZ patients. Neither the presence of T1-hyperintense, diffusion-restricted lesions, nor double positive lesions were associated with improved survival.ConclusionsBaseline T1-hyperintense and diffusion-restricted lesions are not suitable to predict progression-free or overall survival of patients treated with bevacizumab/irinotecan or temozolomide.}, cin = {INM-3}, ddc = {610}, cid = {I:(DE-Juel1)INM-3-20090406}, pnm = {572 - (Dys-)function and Plasticity (POF3-572)}, pid = {G:(DE-HGF)POF3-572}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:31325144}, UT = {WOS:000487899900008}, doi = {10.1007/s11060-019-03246-4}, url = {https://juser.fz-juelich.de/record/863990}, }
