title: PET-CT Passes Test in Head and Neck Cancer.
abstract: A new study of patients with advanced head and neck cancer supports the use of PET-CT to gauge treatment effectiveness. Patients who underwent surgery to remove their lymph nodes survived no longer than patients who underwent PET-CT and had surgery only if their lymph nodes showed signs of residual cancer. In addition, PET-CT surveillance was less expensive.
