Modeling Dose Response for Late Dysphagia in Patients With Head and Neck Cancer in the Modern Era of Definitive Chemoradiation

Abstract

Incidences of both ≥ G2 and ≥ G3 dysphagia were dependent on the mean radiation dose to the total constrictor muscle volume, disease site, and patient age. Limiting the total volume of constrictor muscle to < 58 Gy could keep the predicted rate of ≥ G2 dysphagia to < 5%.
