Overview
Treatment with alpha blockers (example: phenoxybenzamine) followed by beta blockers (example: atenolol) is required before surgery. Adjunctive chemotherapy and radiation are used in metastatic disease.
Medical Therapy
Any surgical option requires prior treatment with both the non-specific alpha adrenoceptor blocker phenoxybenzamine to counteract hypertension and the beta-1 adrenoceptor antagonist atenolol to reduce cardiac output. Given before surgery, these can also block the effect of a sudden release of adrenaline during tumour resection, which would otherwise endanger the anaethetised patient.
Chemotherapy
Metastatic pheochromocytoma is treated with Averbuc protocol which is a combination of cyclophosphamide, vincristine, and dacarbazine.[1]
Radiation
131I-MIBG radiation therapy has been used for the treatment of MIBG-avid metastases.[1]
Contraindicated medications
Pheochromocytoma is considered an absolute contraindication to the use of the following medications:
