Astrocytoma, Grade IV, Giant Cell Glioblastoma, Glioblastoma Multiforme
Conditions
Brief summary
Positron Emission Tomography-Computed Tomography (PET-CT) with injection of 18F-fluoroethylcholine (FEC) could be a useful tool in the evaluation and follow-up of patients who have been diagnosed with glioblastoma multiforme (GBM) and who are treated with radiotherapy and temozolomide by allowing, for example, the distinction of necrosis from tumour tissue. This tool could help the clinician in making therapeutic decisions for GBM patients.
Interventions
60 Gy of external beam radiotherapy using a standard technique will be administered in 2-Gy fractions, for a total of 30 fractions
The chemotherapy will have to be administered in accordance with the protocol used in the CAN-NCIC-CE3 study, which established the current standard for treatment of GBM with the administration of temozolomide as adjuvant therapy at the same time as radiotherapy (clinicaltrials.gov ID NCT00006353).
