Magnetic resonance imaging (MRI) of glioblastoma at the time of diagnosis (left). Glioblastoma was noted to be smaller after initial treatment with chemoradiation and olaparib and was further reduced in size after maintenance temozolomide. On the most recent MRI (right), obtained > 14 months after completion of therapy, the tumor demonstrated further regression, compatible with a durable, near-complete treatment response. TMZ, temozolomide.
