Background: Sympathetic pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumors associated with excess catecholamine production. Routine biochemical and imaging surveillance to monitor for recurrence and metastasis is recommended. However, there is limited data describing optimal surveillance approaches and post-operative biochemical thresholds for detecting recurrences or metastases. This study sought to correlate biochemical and imaging surveillance with ...
