Treatment with radiolabeled somatostatin analogs is a promising tool in the management of patients with inoperable or metastasized neuroendocrine tumors. Symptomatic improvement may occur with all 111Indium-, 90Yttrium-, or 177Lutetium-labeled somatostatin analogs used for peptide receptor radionuclide therapy. If kidney protective agents are used, the side-effects are few and mild, and the median duration of the therapy response is 30 and 40 months, respectively. Overall survival is several years from diagnosis. These data compare favorably with the limited number of alternative treatments. If more widespread use of PRRT can be guaranteed, such therapy may become the therapy of first choice.
