PET Scan results

Recent throat biopsy showed squamous cell cancer in right base of tongue. CT scan revealed numerous lymph node involvement too numerous to count. PET scan today revealed metastatic lymphadenopathy in right paratracheal region measuring up to 2 cm in size with Q-SUV of 15. This is relatively new (6 months) before symptoms with poor swallowing. No lesions to pelvis or abdomen. This infiltrative mass extends to right tonsillar pillar, anterior hypopharynx and jugular chain regions. Are these values to be of concern for surgery first or chemo/radiation?
