Treatment Options for Metastatic Pheochromocytoma

Treatment options for metastatic pheochromocytoma include:

The most common sites of metastasis for pheochromocytoma or extra-adrenal paraganglioma are lymph nodes, bones, lungs, and liver. Patients with known or suspected malignancy should undergo staging with computed tomography or magnetic resonance imaging as well as functional imaging (e.g., with iodine I 123-metaiodobenzylguanidine [MIBG]) to determine the extent and location of disease. Patients are often very symptomatic from excess catecholamine secretion. Phenoxybenzamine is effective, and metyrosine, which is a drug that blocks catecholamine synthesis, can be added if needed.
