Image Guided Reirradiation of High-grade Glioma

Phase 1
Terminated
Conditions
Glioblastoma
Malignant Glioma
Interventions
Radiation: External beam radiotherapy
Registration Number
NCT02025231
Lead Sponsor
Rigshospitalet, Denmark
Brief Summary

The purpose of the study is to evaluate the short- and long term toxicity of radiotherapy to patients with recurrent high-grade glioma who have previously received radiotherapy and to determine the best dose and treatment regimen. Positron emission tomography (PET) using an amino acid tracer, 18-fluoro-ethyltyrosine (18F-FET), is used for target delineation.The study examines, in four sequential treatment groups, the effect of dose, hypofractionation and treatment volume on toxicity. Upon completion of the phase I part, the study progresses to phase II where the best dose- and treatment regimen will be chosen for treatment.

Primary Outcome Measures
NameTimeMethod
Time to neurocognitive declineUp to one year

Time to neurocognitive decline assessed using a test battery comprised of validated tests at multiple time points. (for phase II part of the study)

ToxicityOne year

Early (\<4 weeks) and late (\> 4 weeks) toxicity evaluated by Common Toxicity Criteria ver. 3.0 at multiple time points up to one year after treatment. (for phase I part of the study)

Diagnostic precision of 18F-FET-PET imaging in recurrent high-grade gliomaApproximately one to two weeks prior to radiotherapy

Diagnostic accuracy (positive- and negative predictive value) of 18F-FET-PET guided biopsies (optional procedure) in patients who will receive reirradiation for recurrent high-grade glioma in the study. (for phase I part of the study).

Time to progressionUp to one year

Time to disease progression evaluated by RANO (Response Assessment in Neuro-Oncology) criteria (for phase II part of the study).

Secondary Outcome Measures
NameTimeMethod
Objective response rateUp to one year

Rate of objective tumor responses following treatment evaluated by RANO criteria and by 18F-FET-PET.

Value of 18F-FET-PET in reirradiation of high-grade gliomaOne year

Prognostic value of 18F-FET-PET scan at baseline, value of 18F-FET-PET as an early response marker and correlations between 18F-FET-PET scans and magnetic resonance imaging.
