A Study of Reduced Radiation Therapy With Chemotherapy in People With HPV-Positive Throat Cancer

The 18F-FMISO PET/CT Scan Protocol consists first of an IV bolus injection of approximately 5-10 mCi of the radiotracer. Subjects will undergo 18F-FMISO scan (only 1 injection) occurs at 8-10 treatment days\* into chemoradiation. Each patient will have a baseline staging FDG PET scan which is used to localize the tumor at the primary site and all suspicious cervical neck nodes (\> 1 cm in short axis diameter with focal abnormal increased FDG avidity). These lesions are then assessed on the respective 18F-FMISO PET/CT.

Patients will start with induction chemotherapy of carboplatin, paclitaxel and cetuximab for 6 weeks and when downstaged to T1-2 and \< N3, the patient is eligible to receive concurrent chemoradiation per protocol.A total radiation therapy of 30Gy will be delivered to the oropharynx and neck at 2Gy per fraction per day over 15 days for patients who exhibited no evidence of hypoxia on the intra-treatment 18F-FMISO PET/CT. Concurrent chemotherapy (2 cycles) will be given. After completion of chemotherapy and radiation therapy, a 4 month (+/- 4 weeks)
