High-risk human papillomaviruses (HR-HPV) are the cause of most anogenital cancers and a rising proportion of head and neck squamous cell carcinoma located in the oropharynx (chiefly the tonsils and base of tongue/lingual tonsil) [1,2]. HPV-related cancers account for 60 to 80% of oropharyngeal cancers (OPC) in North America and Northern Europe and could become, in the near future, the predominant type of head and neck malignancies in several western countries [3,4]. Oral and genital HR-HPV infections are both transmitted by mucosal contact and potentially through mucosal secretions most commonly attributed to sexual behaviors [5,6].
