Objective: To estimate the prevalence of oral high-risk human papillomavirus (hr-HPV) infection and the proportion of hr-HPV–related oropharyngeal squamous cell carcinoma (OPSCC) among Indigenous and non-Indigenous populations.
Data Source: Electronic database searches of PubMed, PubMed Central, Embase, MEDLINE, Scope, and Google Scholar were conducted for articles published from January 2000 until November 2019.
Review Methods: Studies were included with a minimum of 100 cases assessing hr-HPV infection in either population samples or oropharyngeal cancer tumor series. The objective was to conduct meta-analyses to calculate the pooled prevalence of oral hr-HPV infection by adjusting for age group or sex in primary studies, the incidence of OPSCC, and the proportion of hr-HPV–related OPSCC in Indigenous people and non-Indigenous/general populations.
Results: We identified 47 eligible studies from 157 articles for meta-analyses. The pooled prevalence of oral hr-HPV infection was 7.494% (95% CI, 5.699%-9.289%) in a general population, with a higher prevalence among men (10.651%) than women (5.176%). The pooled incidence rate was 13.395 (95% CI, 9.315-17.475) and 7.206 (95% CI, 4.961-9.450) per 100,000 person-years in Indigenous and non-Indigenous populations, respectively. The overall pooled proportion of hr-HPV–related OPSCC was 50.812% (95 CI, 41.656%-59.969%). The highest proportion was in North America (60.221%), while the lowest proportion was in the Asia-Pacific (34.246%).
Conclusion: Our findings suggest that in the general population, the prevalence of oral hr-HPV infection is lower among females and those in younger age groups. The incidence of OPSCC was higher among Indigenous than non-Indigenous populations, with the proportion being highest in North America.
