Abstract

Background:Human papillomavirus (HPV) infection is a powerful prognostic biomarker in a subset of head and neck squamous cell carcinomas, specifically oropharyngeal cancers. However, the role of HPV in non-oropharyngeal sites, such as the larynx, remains unconfirmed.Methods:We evaluated a cohort of 324 laryngeal squamous cell carcinoma (LSCC) patients for the expression of p16 INK4A (p16) protein by immunohistochemistry (IHC) and for high-risk HPV E6 and E7 mRNA transcripts by RNA in situ hybridisation (ISH). p16 expression and HPV status were correlated with clinicopathological features and outcomes.Results:Of 307 patients assessable for p16 IHC, 20 (6.5%) were p16 positive. Females and nod..
