An Imaging Agent (89Zr Panitumumab) with PET/CT for Diagnosing Primary Lesions and/or Metastases in Patients with Head and Neck Squamous Cell Carcinoma
This phase I trial evaluates the usefulness of an imaging agent (zirconium Zr 89 panitumumab [89Zr panitumumab]) with positron emission tomography (PET)/computed tomography (CT) for diagnosing primary tumors and/or the spread of disease from where it first started (primary site) to other places in the body (metastasis) in patients with head and neck squamous cell carcinoma. 89Zr panitumumab is an investigational imaging agent that contains a small amount of radiation, which makes it visible on PET scans. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research, 89Zr panitumumab, to allow imaging of the function of different cells and organs in the body. CT utilizes x-rays that traverse the body from the outside. CT images provide an exact outline of organs and potential disease tissue where it occurs in patient’s body. The combined PET/CT scanner is a special type of scanner that allows imaging of both structure (CT) and function (PET) following the injection of 89Zr panitumumab. This 89Zr panitumumab PET/CT may be useful in diagnosis of primary tumors and/or metastasis in patients with head and neck squamous cell carcinoma.
