COSM14: HPV Status and Prognosis for Oropharyngeal Cancers

by Thomas R. Collins •

HPV Epidemic

Take-Home Points

  • The number of sexual partners and the frequency with which a person performs oral sex are two key risk factors of being HPV-positive and developing oropharyngeal cancer, with young, white, college-educated males having the highest risk of oropharyngeal squamous cell carcinoma.
  • Quadrivalent vaccines have shown extremely high efficacy against the acquisition of HPV infections, but vaccine uptake rates still need improvement.
  • The use of biomarkers is being investigated to better understand how to treat different oropharyngeal cancers, but clinical trials are needed to assess these markers.
  • The main goal in the treatment of adult RRP is voice preservation, and using the right tools can make a difference.

An array of experts came together in the panel discussion “HPV in Different Subsites—Clinical Importance and Effect on Therapy” to shed light on a variety of topics concerning human papillomavirus (HPV) status, including risk factors, the effectiveness of vaccinations, the use of biomarkers to predict response to cancer treatment, and guidance on treatment of adults.

Panel moderator Dinesh K. Chhetri, MD, head of the Swallowing Disorders Center at the University of California at Los Angeles, said the discussion provided an up-to-date overview of a topic that’s growing in importance. “I think we should be making physicians aware of this rising HPV epidemic … how it’s changing the landscape of the diseases affected, and how we should change our management as our understanding of the HPV-related diseases increases,” he said.

The prevalence of HPV infections among the healthy U.S. population is only 1%, according to National Health and Nutrition Examination Survey data. But oropharyngeal cancer among men is on the rise, due largely to a rise in HPV-positive cancers, said Carole Fakhry, MD, MPH, assistant professor of otolaryngology-head and neck surgery at Johns Hopkins University in Baltimore.
