| Outline of Final Research Achievements |
We organized “Japan carotid body tumor research group (JCBTRG)” and carried out a survey called “Multi-institutional survey of carotid body tumor in Japan (JCBTRG-1)”. We analyzed 150 patients whose clinical data were obtained from their hospitals and published the article (Oncol Lett 15:3383, 2018). In the next phase, we have been performing the survey called “Multi-institutional survey of the gene mutations of the patients with carotid body tumor in Japan (JCBTRG-2) and analyzing their gene mutations mainly in SDH gene family. Our preliminary results suggested that more than half of the patients with carotid body tumor have SDHB or SDHD germ line mutations. We have established a novel classification of the carotid body tumor which can predict the application of the surgery based on the pre-operative angiography of the patients.
