Response Monitoring Trial in Patients With Suspected Recurrence of Glioblastoma

It was previously shown that 18F-DOPA PET imaging results in intended management changes in 41% of brain tumor patients. However, its impact on patient outcome defined as survival, costs, and/or quality of life has not been demonstrated. Regulatory agencies require randomized trials to determine the impact of PET on patient management and outcome. In this study we hypothesize that the addition of 18F-DOPA PET will improve patient outcome by more accurately identifying presence or absence of tumor recurrence than conventional imaging.
