Abstract
Human papillomavirus (HPV) is a known aetiological factor in the development of oropharyngeal squamous cell carcinomas (OPSCC), however it is a distinct disease to HPV-negative OPSCC. It is more prevalent in younger patients with fewer comorbidities and HPV status is most commonly detected by p16 immunohistochemistry, which acts as a surrogate marker. Until recently, the TNM staging model was wrongly predicting a poor prognosis for many patients by determining an imperfect overall stage, however this has been resolved by an updated edition. Current management of OPSCC is not determined by HPV-status but there are ongoing trials into treatment deintensification to reduce side effects but maintain OS. Furthermore, prognosis is drastically improved in HPV-positive OPSCC.
