Succinate Dehydrogenase Mutations as Familial Pheochromocytoma Syndromes

Surg Oncol Clin N Am. 2023 Apr;32(2):289-301. doi: 10.1016/j.soc.2022.10.006.

Abstract

It is recognized that a large portion of pheochromocytoma and paraganglioma cases will have an underlying germline mutation, supporting the recommendation for universal genetic testing in all patients with PPGLs. A mutation in succinate dehydrogenase subunit B is associated with increased rates of developing synchronous and/or metachronous metastatic disease. Patients identified with this mutation require meticulous preoperative evaluation, a personalized surgical plan to minimize the risk of recurrence and tumor spread, and lifelong surveillance.
