[Surgery or radiotherapy for oropharyngeal HPV-positive tumours?]

Oropharyngeal carcinomas related to the human papilloma virus (HPV; usually HPV16) exhibit biological differences in terms of carcinogenesis and are of relatively better prognosis (in the absence of tobacco consumption) compared to tobacco-related cancers. The therapeutic strategies between these two forms of cancers of the upper aerodigestive tract related to different risk factors are however identical, except therapeutic trial. In the absence of a sufficient level of evidence to define a specific strategy for induced HPV carcinomas, the analysis of the recent literature nonetheless allows us to suggest ways to guide the clinician in his therapeutic choice. Given the relative good prognosis HPV+ oropharyngeal cancers, an important goal is to avoid if possible a multimodal treatment that increases the sequelae and could degrade the quality of life. For the early stages I/II, it may be desirable to propose minimally invasive surgery if radiotherapy is avoidable or an exclusive conformal radiation therapy by intensity modulation in the opposite case. For the advanced stages III/IV, the recommendations are similar to those of cancers not related to HPV. Current trials should provide answers on the relevance of therapeutic deflation (absence of chemotherapy in the event of capsular rupture, dose reduction or irradiation volumes, etc.).
