Study Summary

The purpose of this study is to determine if reducing or eliminating radiation treatment to one or both sides of the neck where there is no evidence of cancer can help spare the side effects of radiation treatment for head and neck cancer. In this study, the investigators plan to reduce the amount of radiation treatment received to healthy tissue

Primary Outcome

* Recurrence in a PN0 neck that was not treated is the critical endpoint in this study. * Recurrence is defined as the return of cancer after treatment * Recurrence is determined by a CT, PET/CT, or MRI and it will be fused with the original treatment planning CT scan. This will allow correlation between the original dose distribution and contours with any recurrent disease.
