Zusammenfassung:Oropharyngeal carcinoma associated with the human papillomavirus is increasing in incidence and represents a unique head and neck disease with favorable treatment outcomes. This review evaluates the evolving role of radiotherapy in regional management with an overall goal of treatment de-escalation in the appropriate patient. Determining the optimal approach and selection factors for treatment de-escalation is under active investigation. Response to induction chemotherapy, refining adverse pathologic factors after a primary surgical approach, decreasing radiation dose with or without chemotherapy in the definitive or adjuvant settings as well as more selective nodal level irradiation all are current strategies for treatment de-escalation. This review details the likely changes in regional radiotherapy management for oropharyngeal carcinoma in the modern human papillomavirus era and discusses future approaches to patient selection with the goal of reducing toxicities while maintaining function preservation and quality of life in group of patients who are younger and healthier than traditional head and neck cancer patients.
