| Outline of Final Research Achievements |
We analyzed 80 fresh frozen samples using next generation sequencing. The samples were obtained in patients with previously untreated stage Ⅲ/Ⅳ oropharyngeal cancer who underwent multimodality therapy at 14 Japanese hospitals that were the member of the Japan Cooperative Study Group for Basic Research in Head and Neck Cancer.
Among 80samples, HPV+ was 56 cases (70%) and HPV- was 24 cases (30%). In HPV+ samples, PIK3CA was the most common genomic alteration (12, 21.4%), the second one was FGFR3 (5, 8.9%) and the third one was PTEN (4, 7.1%). In HPV- samples, TP53 (11, 45.8%) was most frequently altered.These results indicate that genomic alterations in Japanese oropharyngeal cancers are not different in those in other countries. We may have to consider the different treatment by HPV status.
