About

Oropharyngeal squamous cell carcinoma (OPSCC) incidence is increasing rapidly in the developed world. This has been attributed to a rise in Human Papillomavirus (HPV) infection. HPV+OPSCC is considered a distinct disease entity, affecting younger patients and has a good prognosis following treatment. Subsequently, patients can live with the considerable side effects for several decades.

Radiotherapy and cetuximab (Epidermal Growth Factor Receptor-inhibitor) have demonstrated similar efficacy to 'platin' chemoradiotherapy (current standard treatment containing platinum-based compounds) in head and neck cancer, but is potentially less toxic.

Results of this trial will be used to determine the optimum treatment of this debilitating cancer, with the primary aim of decreasing toxicity and improving quality of life for HPV+OPSCC patients.
