About this study

The goal of this clinical trial is to learn whether for intermediate-risk patients who have undergone Transoral Robotic Surgery for HPV/p16(+) oropharyngeal cancer and have minimal smoking history, whether these patients can be treated with a lower-than standard dose, with omission of the primary site in the oropharynx. The main questions it aims to answer are: Does radiotherapy site and dose-de-escalation lead to similar outcomes compared to historical data on tumor control in patients who are treated with standard radiation doses and treatment fields? Participants will: Undergo treatment with a lower than standard radiation dose (50Gy in 25 fractions, with either Intensity Modulated Radiation Therapy (IMRT) or proton beam therapy) and to a smaller than standard radiation field (to the neck only, excluding the original site of tumor in the oropharynx)
