title: [Human papillomavirus and cancer of the oropharynx. Molecular interaction and clinical implications].
abstract: One-third of the cases of oropharyngeal squamous cell carcinoma (OSCC) contain oncogenic human papillomavirus (HR-HPV). Epidemiologic and molecular evidence underlines the causal role of HR-HPV in these tumors, which can be defined as HPV-related OSCC. These tumors differ from chemical/toxin-induced OSCC in several biological aspects, including specific molecular and genetic alterations. This leads to a characteristic clinical profile of HPV-related OSCC. Sexual risk factors play a role; however, the knowledge about natural infection and the rate of persistence of HR-HPV in the oropharynx is marginal. It is shown that the distinct biological behavior of the HPV-related subset of oropharyngeal tumors results in a more favorable prognosis. This might be the result of a better response to chemotherapy and radiotherapy. However, further studies are needed to show whether it will be possible to reliably select patients for individualized therapy depended on the HPV status of their tumors. Therefore, we think it will be mandatory to consider and stratify HPV status in the design of prospective clinical trials in the future.
