Summary

This is a single-arm Phase II study of adjuvant radiation for locally advanced p16+ oropharyngeal squamous cell carcinoma. The main purpose of this research is to determine the likelihood of cancer growing back in the throat or in the neck two years after completion of radiation if lower doses of radiation are used to a smaller area of the head and neck region than is currently used in standard of care.

Description

This is a single arm Phase II study of adjuvant radiation for locally-advanced p16+ oropharyngeal squamous cell carcinoma. Patients with pT0-T3, N0-N2b, M0 disease (per AJCC 7th ed) with <5 positive lymph nodes, will be eligible. Patients will have undergone TORS primary site resection and ipsilateral neck dissection. Patients will undergo radiation dose reduction and target volume reduction.
