How common is pseudoprogression in glioblastoma?
Twenty to thirty percent of patients undergoing their first postchemoradiation MRI show increased contrast enhancement that ultimately resolves without any change in therapy.
Are there any radiographic criteria to determine tumor progression?
The Response Assessment in Neuro-Oncology (RANO) criteria are used, which incorporates an increase in fluid attenuated inversion recovery hyperintensity as a way to measure nonenhancing tumor progression.
