Impact of Positron Emission Tomography/Computed Tomography
BACKGROUND: In head and neck cancer (HNC), 3-month post-treatment positron emission tomography (PET)/computed tomogra-phy (CT) reliably identifies persistent/recurrent disease. However, further PET/CT surveillance has unclear benefit. The impact of post-treatment PET/CT surveillance on outcomes is assessed at 12 and 24 months.
