This trial studies how well standard and delayed fludeoxyglucose F-18 (FDG)-positron emission tomography (PET)/computed tomography (CT) given after standard radiation and chemotherapy works in assessing patients with head and neck squamous cell cancer that has spread to other places in the body. Diagnostic procedures, such as PET/CT, use radioactive material, such as fludeoxyglucose F-18, to find and diagnose head and neck tumors and may help to find out how far the disease has spread.
Study sponsor and potential other locations can be found on ClinicalTrials.gov for NCT03575949.
PRIMARY OBJECTIVE:
I. To assess the optimal imaging time using FDG positron emission tomography (PET) with comparison between a standard of care 1-hour scan (early) and the research scan of 3-hours scan (delayed) post radiotracer administration that maximizes separation of activity between lesion and non-lesional parenchyma (measured as lesion/background [L/B] ratio) in patients with head and neck primary squamous cell carcinoma following chemoradiation treatment.
OUTLINE:
Patients receive fludeoxyglucose F-18 intravenously (IV) over 1 minute and undergo PET/CT at 70 and 180 minutes after injection at 12-14 weeks following standard chemoradiation (CRT) completion.
After completion of study, patients are followed up at 30 days and then periodically for up to 6 months.
