This study aimed to identify the prevalence of HPV infection in OCSCC. A systematic search on PubMed and EMBASE was performed, including articles assessing the prevalence of HPV-positive (HPV+) OCSCC published from January 2017 to December 2022. OCSCC was considered HPV+ by the detection of HPV DNA, HPV RNA, and\/or p16 overexpression in the tumor mass. A meta-analysis was made determining the overall HPV+ OCSCC prevalence. We included 31 studies comprising 5007 patients from 24 countries. The study size ranged from 17 to 940 patients. The HPV+ OCSCC proportion variated widely and ranged from 0% to 37%. Tumors in the tongue were the predominant sublocation for HPV in the oral cavity. The meta-analysis revealed that the overall HPV+ OCSCC prevalence is 6% (95% CI; 3\u201310%), and only one study found HPV and OCSCC significantly associated. Thus, HPV may not be a necessary or a strong risk factor in OCSCC oncogenesis, and the possibility of a site misclassification of a mobile tongue with the root of the tongue cannot be excluded.<\/jats:p>","DOI":"10.3390\/v15020451","type":"journal-article","created":{"date-parts":[[2023,2,6]],"date-time":"2023-02-06T04:08:07Z","timestamp":1675656487000},"page":"451","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":117,"title":["The Prevalence of HPV in Oral Cavity Squamous Cell Carcinoma"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5788-4933","authenticated-orcid":false,"given":"Seyed Keybud","family":"Katirachi","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngologi, Head & Neck Surgery and Audiology, Rigshospitalet, 2100 Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0679-4254","authenticated-orcid":false,"given":"Mathias Peter","family":"Gr\u00f8nlund","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngologi, Head & Neck Surgery and Audiology, Rigshospitalet, 2100 Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathrine Kronberg","family":"Jakobsen","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngologi, Head & Neck Surgery and Audiology, Rigshospitalet, 2100 Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Gr\u00f8nh\u00f8j","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngologi, Head & Neck Surgery and Audiology, Rigshospitalet, 2100 Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6753-8129","authenticated-orcid":false,"given":"Christian","family":"von Buchwald","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngologi, Head & Neck Surgery and Audiology, Rigshospitalet, 2100 Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,6]]},"reference":[{"key":"ref_1","unstructured":"(2022, December 12).
