Vaccinations have shown a decrease in human papillomavirus (HPV) infection-related cervical cancer in women, but there has been a sharp rise in the HPV infection-related oropharyngeal cancer cases over the past few decades. Recent studies have suggested the association of HPV infections with tonsillar cancers as well and suggestions regarding preventive tonsillectomies in order to achieve a decrease in HPV infection-related oropharyngeal or tonsillar cancer have arisen. However, there is limited cumulative evidence validated at a global level to support the endorsement of this strategy. This research revolves around the concept of burden of tonsillar carcinomas due to oropharyngeal HPV infection. Thus, a systematic review and meta-analysis of existing studies was undertaken to estimate the pooled prevalence of tonsillar cancer associated with oropharyngeal HPV infection. Published articles on tonsillar cancer with and without HPV infection from PubMed, Embase, Scopus and Web of Science were systematically searched from inception until 23 December 2021. A random-effects model was used to estimate the pooled prevalence forest plots. The systematic review revealed that 50% of the reported cases of tonsillar cancer had an oropharyngeal HPV infection, questioning the preventive nature of an early tonsillectomy which is essentially an invasive surgical procedure. Large heterogeneity was reported in the included studies, and there was insufficient data for sub-group analysis. Future research and representative studies are required to thoroughly explore the correlation between HPV infection and tonsillar cancer.
