There is no accepted staging system for pheochromocytoma.

LOCALIZED BENIGN

Data suggest that for patients with resectable, benign pheochromocytoma, the overall survival is equal to that of the age-matched normal population.[1,2]

REGIONAL

No information is available at this time.

METASTATIC

Data from several series suggest that the 5-year survival rate for patients with metastatic, malignant pheochromocytoma is approximately 40%.[1,2,3] In three retrospective studies of patients with either metastatic or recurrent pheochromocytoma, the 5-year survival ranged from 32% to 60%.[4]
