Official Title: Improvement of Local Control in Skull Base, Spine and Sacral Chordomas Treated by Surgery and Protontherapy Targeting Hypoxic Cells Revealed by [18F]FAZA) PET/CT Tracers
Brief Summary: Improved local control of chordoma initially treated with surgery or not, thanks to adjuvant radiotherapy oriented by conventional imaging Computed Tomography /Magnetic Resonance Imaging (CT / MRI) and guided by the [18Fluor] ([18F]) Fluoroazomycin Arabinofuranoside (FAZA) Positron Emission Tomography / Computed Tomography (PET / CT) to target the radioresistant hypoxic cells.
