Landscape assessment for gender neutral human papillomavirus vaccination recommendations including head and neck cancer burden data

Introduction: Head and neck cancers (HNC) accounted for over 450,000 deaths and 900,000 cases in 2018 worldwide. Of those, 38,000 cases were attributable to human papillomavirus (HPV). HNC is two to four times more prevalent in men than in women. The incidence of oropharyngeal cancers (OPC) and oral cavity cancers caused by HPV has increased in recent decades. Given the substantial burden of HPV-related HNC in males, this study aimed to assess whether and how national agencies included HPV-related HNC when evaluating HPV genderneutral vaccination (GNV) programs. Methods: A systematic literature review was conducted in MEDLINE (R) and EMBASE (R), and on the websites of selected national agencies. Results: Searches identified a potential 205 records; seventeen were eligible for the review. Seventy percent of assessments were published by European countries and most were recent (2014-2019). Eleven (65%) reports considered OPC when discussing HNC, and a few included other anatomic sites. All reports that considered incidence data were in consensus that incidence of OPC was higher in men and showed that the mortality rates for HPV-related HNC were also higher in men. When looking at the economic impact, the incremental cost-effectiveness ratios in the assessments varied widely, as the inputs into the analyses were heterogeneous. However, several reports concluded GNV programs were likely to be cost-effective versus not vaccinating males. Conclusion: The burden of HPV-related HNC in the general male population has been recognized by several Heatlth Technology Assessment (HTA) agencies and National Immunization Technical Advisory Groups (NITAGs) when evaluating HPV GNV programs. The assessments identified on GNV programs strongly indicate a cost-effective clinical benefit. Nevertheless, the epidemiological burden of HNC may have been underestimated in some countries due to limited data. Further research is crucial to obtain more robust data that will help address the information gap in epidemiological and economic burden of HPV-associated HNC in men. (C) 2021 The Authors.

Automated summary

Head and neck cancers, particularly those related to HPV, pose a significant burden worldwide, with a higher incidence in men. Evaluations of HPV gender-neutral vaccination programs by European countries suggest that they are likely to be cost-effective.
