| Research Abstract |
In Japanese malignant pheochromocytoma patients, we detected SDHB mutation in 10 cases, including large deletion. Also, we detected germline TMEM127 mutation (c.116_119delTGTC, p.Ile41ArgfsX39) associated with 2q deletion loss of heterozygosity with bilateral adrenal pheochromocytoma. We have, for the first time, introduced the hypothesis that the antitumor effect of sunitinib observed in malignant pheochromocytomas seems to be associated with direct effects on tumor cells.
