<jats:title>Background</jats:title>
<jats:p>Oropharyngeal squamous cell carcinoma (OPSCC) is the only subgroup of head neck cancer that presents with an increased incidence. Gender-specific studies in other cancer entities have revealed differences in treatment response and prognosis. However, only limited data in OPSCC according to gender and human papillomavirus (HPV) status exist. Therefore, we aimed to investigate sex-specific differences in OPSCC and how these may be distributed in relation to HPV and other risk factors.</jats:p>

<jats:title>Methods</jats:title>
<jats:p>This retrospective, bicentric study included 1629 patients with OPSCC diagnosed between 1992 and 2020. We formed subgroups based on TNM status, American Joint Cancer Committee 8<jats:sup>th</jats:sup> edition (AJCC8), HPV status, treatment modality (surgery (± radio(chemo)therapy (RCT) vs. definitive RCT) and patient-related risk factors and investigated gender differences and their impact on patients survival via descriptive-,uni- and multivariate analysis.</jats:p>

<jats:title>Results</jats:title>
<jats:p>With the exception of alcohol abuse, no significant differences were found in risk factors between men and women. Females presented with better OS than males in the subgroup T1-2, N + , independent of risk factors (<jats:italic>p</jats:italic> = 0.008). Males demonstrated significant stratification through all AJCC8 stages (all <jats:italic>p</jats:italic> < 0.050). In contrast, women were lacking significance between stage II and III (<jats:italic>p</jats:italic> = 0.992). With regard to therapy (surgery (± R(C)T) – vs. definitive RCT) women treated with surgery had better OS than men in the whole cohort (<jats:italic>p</jats:italic> = 0.008). Similar results were detected in the HPV-negative OPSCC sub-cohort (<jats:italic>p</jats:italic> = 0.042) and in high-risk groups (AJCC8 stage III and IV with M0, <jats:italic>p</jats:italic> = 0.003).</jats:p>
</jats:sec><jats:sec>
<jats:title>Conclusion</jats:title>
<jats:p>Sex-specific differences in OPSCC represent a health disparity, particularly according to staging and treatment, which need to be addressed in future studies.</jats:p>
