Disparities in Proton Radiation Utilization for HPV‐Associated Oropharyngeal Cancer Following TORS

Head &Neck, EarlyView.
ABSTRACT Introduction Racial, socioeconomic, and geographic disparities in receipt of proton radiation have been reported. Whether disparities exist for oropharyngeal squamous cell carcinoma (OPSCC) is not well studied. Methods Patients with HPV‐associated OPSCC treated with transoral robotic surgery (TORS) and adjuvant radiation from 2016 to 2023 were
