ABSTRACT
High-risk human papillomavirus (HR-HPV), particularly type 16, is now recognised as a causative agent in a subset of oropharyngeal squamous cell carcinomas (OPSCCs). These tumours are on the increase and generally have a better prognosis than their HPV negative counterparts. This raises the question of de escalation therapy to reduce long term consequences in a younger cohort of patients with a long life expectancy. Several clinical trials with anti-epidermal growth factor receptor (EGFR) therapies, particularly cetuximab, are ongoing. Few data exist on the relationship between EGFR and HPV induced oropharyngeal cancers. We summarise the main studies in relation to EGFR alterations (gene copy number, protein expression and mutations) and the impact on prognosis of HPV positive tumours that express high levels of EGFR. We also discuss the opportunity of targeting this pathway in light of recent studies.
