FAZA PET/MRI Sarcoma
Sponsor: University Health Network, Toronto
Summary
This is a dual arm, single centre, investigator initiated study to investigate the use of FAZA-PET in combination with MRI. FAZA is an investigational radiotracer used in PET scans. FAZA PET/MRI will be used to measure hypoxia in sarcoma tissues and will occur for: Arm A: before neo-adjuvant radiation/chemotherapy treatment; Arm B: before surgery (optional). After the FAZA PET/MRI scan, patients will be followed up via telephone, 48 hours after the scan, to see if there are any side effects due to FAZA. Up to 50 patients enrolled in Arm B will receive pimonidazole approximately 16-20 hours before surgery.
Official title: A Prospective Study of Hypoxia Imaging in Patients With Soft Tissue Sarcoma Using Positron Emission Tomography (PET) With 18F-Fluoroazomycin Arabinoside (18F-FAZA) in Combination With MRI

18F-FAZA
18F-FAZA is a radiotracer used for PET imaging (in combination with MRI) to detect hypoxia in tumours. This scan will be done before and after their radiation treatment.
Pimonidazole
Pimonidazole is a drug that will attached to areas in the tumour that are low in oxygen. When this occurs, the areas of the tumour that are low in oxygen can be more easily found and studied after surgical removal.
