Abstract
The measurable mean maximum resting displacement for the GTV indicates that tumor motion occurs even when the patient is not swallowing. Nonuniform margins should be used as a standard PTV margin that accounts for setup error and tumor motion in radiotherapy of HNC unless adaptive radiotherapy with respect to intrafraction tumor motion is performed. The PTV margin can be individualized to a single patient's swallowing characteristics or calculated as an average based on the swallowing data from the cohort.
