Clinicopathologic features and molecular characterization of oropharyngeal carcinomas harboring low-risk human papillomavirus.
Although the association between high-risk (HR) subtypes of human papillomavirus (HPV) and oropharyngeal carcinoma (OC) is well established, the role and biologic significance of low-risk (LR) HPV in these tumors remains poorly understood. In this series, we present 4 OCs with LR-HPV positivity by in situ hybridization...
