Abstract
Human papillomavirus-associated oropharyngeal cancer (HPV-OPC) is a distinct clinical entity with a favorable prognosis compared with non-HPV-OPC. Surgery and radiotherapy (RT) result in adverse effects, and negative quality of life or functional outcomes, which impact a significant proportion of HPV-OPC survivors. Ongoing studies aim to reduce these negative treatment effects while maintaining high cure rates through deintensified therapy typically use either a primary surgical or RT approach. A single-day curative surgery will remain relevant for many patients with early-stage disease. However, the average patient with HPV-OPC will have indications for adjuvant therapy. A primary RT approach to deintensified therapy has more available data from patients on prospective multi-institutional trials, provides broader patient selection, and may be more cost-effective. Anticipated results from an active phase II/III NCTN trial will help guide the standard of care using primary RT. Next generation trials will help further refine patient selection and/or radical deintensification (30-50 Gy).
