CONTRERAS, William  y  VENEGAS, Bernardo. Human Papilloma virus in Oral and Oropharyngeal Cancer: Review of the Literature. Int. J. Odontostomat. [online]. 2015, vol.9, n.3, pp.427-435. ISSN 0718-381X.

Recent studies indicate what has become a nearly inescapable reality in that Human Papilloma Virus can be associated to the development of Oral and Oropharyngeal Squamous Cell Carcinoma. Since the discovery of zur Hausen et al. that helped define the mechanism by which HPV causes normal keratinocyte transformation to a malignant state, there have been numerous studies that have described the presence of HPV in head and neck carcinomas, specifically in oral cavity and oropharynx. The detection of the virus in these carcinomas may have important clinical implications in the prognosis and treatment of these tumors with more favorable patient outcomes; likewise, justify prevention plans aimed at early diagnosis and specific protection against HPV. Currently minimally invasive experimental therapies that boost the immune system to attack these tumors are in development, however, they are not yet approved for general use. In Chile there are no studies that describe the current situation with regard to HPV Squamous Cell Carcinoma in oral cavity and oropharynx that may guide the health system regarding the prevention and treatment of this cancer. In this review we present the principal aspects that associate the virus with this type of oral and oropharyngeal carcinoma. We reviewed indexed articles in English (Pubmed, Scopus, Cochrane Library, Google Scholar) and Spanish (SciELO, Google Scholar), with the objective to provide Dental Surgeons and specialists the most updated information about this subject. The review was developed considering the epidemiology as well as the carcinogenic mechanisms of the virus, advanced diagnostic techniques, ways of prevention and state of the art in treatment matters.
