Outline of Final Research Achievements |
Changes of oral microbiota of oral cancer patients, who underwent concomitant chemoradiotherapy (CCRT), were analyzed by using next generation sequencer (NGS). 1. The number of the species of bacteria decreased after CCRT and distribution ratios of Neisseria flavescent and Fusobacterium periodonticumbacteria lowered after CCRT. 2. distribution ratios of Scardovia wiggisiae and Oribacterium asaccharolyticum of CCRT group were higher than those of non-CCRT group.

Academic Significance and Societal Importance of the Research Achievements |
Fusobacterium periodonticum は揮発性硫黄化合物(VSC)として口臭の原因ともされていることから、いっそう詳細な検討が必要である。 さらにScardovia wiggisiaeはう蝕との関連が指摘されている菌種でもあることから、口腔がん患者に対して化学放射線治療を施行した場合には患者のう蝕リスクが高まるおそれが示唆された。
