Prognostic impact of intra tumoral HPV-16 viral load in oropharyngeal squamous cell carcinomas.

Objectives: The incidence of HPV-induced oropharyngeal squamous cell carcinoma (OSCC) is constantly increasing. Although HPV-related OSCC carry a better prognosis, the majority of patients with an HPV-positive OSCC have other prognostic factors such as tobacco smoking, making therapeutic de-escalating approaches less precise. In this context, our study aims to evaluate the prognostic impact of intra-tumoral HPV-16 viral load (VL) in OSCC.
