(131)I-MIBG treatment of pheochromocytoma: low versus intermediate activity regimens of therapy.

Abstract

We demonstrated that intermediate single session activity shortened to one third the global treatment time, with similar efficacy and a moderate increment of toxicity. Consequently, the increase of (131)I-MIBG activity, without reaching myeloablative levels, can be recommended for standard treatment of pheochromocytoma and paraganglioma patients.
