| Outline of Final Research Achievements |
The aim of the present study is to contribute the diagnosis and risk classification of human papillomavirus (HPV) related head and neck cancer. The major achievements of the present study are as follows,
The 8th edition of the AJCC staging manual reflects the prognosis of OPSCC using p16 immunoreactivity for the detection of HPV-mediated OPSCC. The discordance between p16 overexpression and the presence of HPV DNA in relation to survival outcome should be clarified to design a de-escalation study.Laryngeal cancer (LC) patients with HPV infection and high levels of p16 expression might have an improved survival outcome; however, it is necessary to recruit additional LC cases with HPV infection to determine the definitive characteristics of HPV-mediated LC and estimate survival outcome. These results may contribute to the development of a useful method for selecting patients with a potentially fair response to treatment and ensure laryngeal preservation.
