Risk of new tumor, carotid stenosis, and stroke after stereotactic radiosurgery for pituitary tumor: A multicenter study of 2254 patients with imaging follow-up

A higher risk of secondary brain tumor, carotid stenosis, and stroke has been reported after conventional sella irradiation for pituitary neuroendocrine tumors (PitNET). Stereotactic radiosurgery (SRS), which is a more focused approach, is now increasingly used instead. The aim was to assess the risk of secondary brain tumor, carotid stenosis/occlusion, and stroke after SRS.
