60 Gy to primary site and 50 Gy to neck with protons.

The patient should receive radiation and perhaps consider chemotherapy.
I would use 60 Gy to postop bed.
I usually give 40 Gy to subclinical nodal region levels Ib-IV and RO regions.
Unless tumor very posterior and there is no concern for level IB spread.
Standard constraints to all normal tissue....
