#4208 The somatostatin system – A silent messenger in pheochromocytomas and paragangliomas?

Introduction: Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine neoplasms (NENs) arising from neural crest-derived chromaffin cells. Due to the abundance of somatostatin receptors (SSTs) on the surface of most NENs, somatostatin analogues (SSAs) have become a cornerstone in their diagnosis and treatment. However, while PPGLs exhibit this feature, their functional responsiveness to SSAs remains limited, with the underlying cause of this resistance being still elusive.
