BACKGROUND: The incidence of oropharyngeal carcinomas associated with human papillomavirus (HPV) is continuously increasing. HPV-positive and -negative oropharyngeal carcinomas have different epidemiological, clinical, and molecular features, with HPV-positive tumors having a better response to treatment and better prognosis. An adequate staging system for HPV-related oropharyngeal carcinomas is needed, as the American Joint Committee on Cancer 7th Edition did not consider their unique biological behavior. At present, oropharyngeal carcinomas are subdivided into p16 positive and p16 negative tumors, based on their expression of p16, a surrogate marker of high-risk HPV. PURPOSE: This review summarizes current knowledge of HPV-associated oropharyngeal carcinomas with emphasis on their molecular features and histopathology, as well as summarizes and compares HPV detection methods and genotyping techniques. This review also describes the prognostic significance of p16 expression in these tumors and significant changes in the staging of oropharyngeal carcinomas based on p16 expression, together with the justifications for these changes. Finally, this review reports the recommendations of the College of American Pathologists for testing HPV in head and neck cancers, supported by the American Society of Clinical Oncology.
