Resumen
Pheochromocytomas and paragangliomas are rare neuroendocrine tumours that originate from the adrenal medulla or extra-adrenal sympathetic or parasympathetic ganglia. They have the potential to secrete catecholamines, leading to e.g., hypertension. The only curative treatment modality is radical surgery. In disseminated diseases, limited data are available to guide proper medical treatment. Peptide receptor radionuclide therapy (PRRT) represents a rather novel treatment modality for these tumours. In the present nation-wide study, including all patients (n = 28) treated with PPRT in Denmark, we show a median overall survival of 72 and a median progression-free survival of 30 months with low toxicity. In conclusion, PRRT seems to represent an effective treatment option. The sequence of PRRT in treatment algorithms for pheochromocytomas and paragangliomas remains to be clarified.
