Abstract
Locoregional recurrence remains common after treatment of head and neck cancer, warranting careful surveillance in follow-up. Although randomized data support an initial positron emission tomography/computed tomography several months after treatment, evidence supporting subsequent imaging is limited, and most recurrences ultimately manifest clinically. Cooperative group studies and consensus guidelines vary widely in their recommendations regarding surveillance imaging. Patients with indeterminate findings, new symptoms, or areas difficult to examine in clinic may avoid invasive and potentially morbid interventions with judicious use of subsequent imaging. For any patient undergoing posttreatment imaging, standardized reporting criteria provide a framework for risk-stratification that can enhance communication and potentially guide management.
