What was measured

* 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.

Groups in this outcome

Arm 1: IMRT

CTV1 = 66 Gy in 33 fractions CTV2 = 60 Gy in 33 fractions CTV3 = 56 Gy in 33 fractions CTV3 Proto = 56 Gy in 33 fractions
