The incidence of oropharyngeal cancer (OPC) has increased in the last two decades in spite of the global reduction in tobacco use, the primary risk factor for this neoplasm [1]. This fact has been attributed to OPC's association with human papillomavirus (HPV) [1,2]. It is expected that if the incidence of HPV-associated OPC continues to increase, it will exceed the HPV-associated cervical cancer in prevalence by 2020 [3].
