Symptom burden and dysphagia associated with osteoradionecrosis in long-term oropharynx cancer survivors: A cohort analysis

The annual estimated incidence of oropharynx cancer is approximately 130,300 cases per year worldwide with an estimated 15,000 new cases diagnosed annually in the United States [1,2]. Over the last few decades, the incidence of oropharynx cancer has been increasing dramatically in developed countries such as the United States, Canada, Australia, the United Kingdom, Denmark, the Netherlands, Norway and Sweden [3]. This rise in the incidence of oropharynx cancer is attributed to human papillomavirus (HPV).
