40-year incidence trends for oropharyngeal squamous cell carcinoma in the United States

There were an estimated 61,760 incident cases of head and neck cancer (oral cavity, pharynx, oral cavity, and larynx) in the United States in 2016, accounting for about 3.7% of all new cancer cases [1]. Among oral cavity and pharynx cancer, oral cavity cancer rates are decreasing mostly due to decreases in smoking and alcohol use [2,3]. However, cancers of the base of tongue, tonsil, and oropharynx (oropharyngeal cancer) are increasing because of increases in human papillomavirus (HPV) infection.
