What is the utility of 12- and 24-month PET-CT surveillance in detecting recurrence in patients with head and neck cancer?
Background: The optimal use and timing of PET-CT in the surveillance of patients with head and neck cancer remains a point of debate without clear guidelines. A three-month post-treatment PET-CT scan has a high negative predictive value and is a favorable prognostic factor. In such patients, it is unclear whether further PET/CT surveillance is useful or cost effective.
