Conclusions:
These data suggest that the radiation dose that is delivered to the larynx and pharyngeal constrictor muscles plays an important role in the risk of long term PEG tube dependency for patients with head and neck cancer who are treated primarily with radiation. Threshold values have been evaluted and will require further confirmatory study.
