Abstract
In recent times, metabolic response to chemoradiotherapy has become possible due to the clinical application of 18F-fluorodeoxyglucose PET. Its utility in the initial staging of head and neck cancer is becoming widely accepted, however, its role in the post-therapy management of the neck following chemoradiotherapy in node-positive head and neck cancer remains unresolved. This article examines the role of PET in the restaging of patients who achieve a complete response at the primary site following radiotherapy. In particular, the authors examine its potential use in the assessment of post-therapy residual nodes and its role in sparing patients from an unnecessary neck dissection in order to minimize treatment-related morbidity.
