Human papillomavirus, oropharyngeal cancer, and the latest vaccine: considerations for oral healthcare providers.

Abstract

Human papillomavirus (HPV) is associated with both benign and malignant disorders, such as genital warts and a variety of cancers, including oropharyngeal squamous cell carcinomas (OPSCCs). The current 9-valent HPV vaccine (Gardasil 9) protects against high-risk strains that have been shown to cause OPSCC, and widespread vaccination should reduce the rate of all HPV-associated cancers. HPV-related OPSCCs differ from non-HPV-related OPSCCs in their clinical presentations and responsiveness to treatment. To provide oral healthcare providers with a basis for effective com-munication with patients, this article will examine the evolution of the HPV vaccination schedule and the role of the HPV vaccine in the prevention of OPSCCs.
