Definitive radiochemotherapy or initial surgery for oropharyngeal cancer

Background The decision between definitive radio(chemo)therapy (RCT) or a surgical strategy, i. e. surgery ± adjuvant radio(chemo)therapy for optimal treatment of oropharyngeal cancer is highly debated. Human papillomavirus(HPV)-related tumours are a distinct entity associated with p16 overexpression. While this represents a major prognostic factor, its predictive significance remains unknown.
