Background: Oral human papillomavirus (HPV) is common among healthy individuals but causes and implications of persistent infections are under evaluation in the pathogenesis of head and neck neoplasms. Methods: This was a retrospective study evaluating the prevalence of high-risk (HR), probable HR and low-risk (LR) HPV types in patients reporting signs/symptoms of oral and upper respiratory tract lesions. Individuals attending between 2019 and 2022 a University Hospital in Milan, Italy, with risk factors for HPV (unprotected oral sex and/or previous documentation of HPV infection in oral and upper respiratory tract and/or another anatomical site) were included. Results: Fourteen out of 110 (12.7%) individuals tested positive for HPV DNA. The prevalence of HR-HPV and LR-HPV was 3.6% (4/110) and 9.1% (10/110), respectively. No probable/possible HR-HPV was detected. Specifically, 10/110 (9.1%) were diagnosed with 1 LR-HPV genotype, 3/110 (2.7%) were infected with 1 HR-HPV and 1/110 had 3 concomitant HR-HPV types. HPV 16 (2.7%, 3/110) and 6 (4.5%, 5/110) were the most common HR and LR types, respectively. One patient positive for HPV 16, 33 and 35 was diagnosed with cancer at the base of the tongue. Two individuals among those who tested positive for HPV DNA reported previous HPV vaccination. Conclusions: Our data, in line with observations from previous prevalence studies, support the potential role of HPV in head and neck neoplasms. HPV DNA testing should be performed in patients presenting lesions in oral/respiratory tracts and risk factors for HPV. Improvement in HPV vaccination coverage is warranted.

Abstract

Background: Oral human papillomavirus (HPV) is common among healthy individuals but causes and implications of persistent infections are under evaluation in the pathogenesis of head and neck neoplasms. Methods: This was a retrospective study evaluating the prevalence of high-risk (HR), probable HR and low-risk (LR) HPV types in patients reporting signs/symptoms of oral and upper respiratory tract lesions. Individuals attending between 2019 and 2022 a University Hospital in Milan, Italy, with risk factors for HPV (unprotected oral sex and/or previous documentation of HPV infection in oral and upper respiratory tract and/or another anatomical site) were included. Results: Fourteen out of 110 (12.7%) individuals tested positive for HPV DNA. The prevalence of HR-HPV and LR-HPV was 3.6% (4/110) and 9.1% (10/110), respectively. No probable/possible HR-HPV was detected. Specifically, 10/110 (9.1%) were diagnosed with 1 LR-HPV genotype, 3/110 (2.7%) were infected with 1 HR-HPV and 1/110 had 3 concomitant HR-HPV types. HPV 16 (2.7%, 3/110) and 6 (4.5%, 5/110) were the most common HR and LR types, respectively. One patient positive for HPV 16, 33 and 35 was diagnosed with cancer at the base of the tongue. Two individuals among those who tested positive for HPV DNA reported previous HPV vaccination. Conclusions: Our data, in line with observations from previous prevalence studies, support the potential role of HPV in head and neck neoplasms. HPV DNA testing should be performed in patients presenting lesions in oral/respiratory tracts and risk factors for HPV. Improvement in HPV vaccination coverage is warranted.
