We retrospectively included in a tertiary center between 2014 and 2020 mucosal squamous cell carcinomas of the head and neck in adult. First outcome was the prevalence of HPV cancer. Secondary outcomes were overall survival (OS) at 2 and 5 years and disease-free survival (DFS). A total of 508 patients were enrolled, resulting in 537 cases of mucous squamous cell carcinoma of the head and neck (n = 29 synchronous carcinomas). Clinical, pathological, and survival data were collected, and a double PCR for HPV with genotyping was performed on most of the samples. The HPV prevalence in the cohort was 28.2%, with HPV 16 being the predominant genotype (87%).
