| Outline of Final Research Achievements |
In recent years, the prevalence of human papilloma virus (HPV)-related oropharyngeal cancer is increasing in European countries and the United States, and it is also becoming increasingly relevant in clinical practice in Japan. In response to this, we widely elucidated the association of HPV in Japanease head and neck cancer cases, such as oropharyngeal cancer and sinonasal cancer coexistent with inverted papilloma. In addition, as a result of the micro RNA microarray using extracted RNA from formalin-fixed paraffin-embedded oropharyngeal cancer specimens, we revealed micro-RNAs showing specific changes in expression in Japanese HPV-related oropharyngeal cancer cases. These could be implemented as a new prognostic or carcinogenic biomarker of HPV-related oropharyngeal cancer in the future.
