Peptide Receptor Radionuclide Therapy Using 225Ac-DOTATOC Achieves Partial Remission in a Patient With Progressive Neuroendocrine Liver Metastases After Repeated ß-Emitter Peptide Receptor Radionuclide Therapy.

ABSTRACT

We present here a case with ß-radiation-refractory metastatic neuroendocrine tumors, who demonstrated an excellent therapy response after 1 cycle of Ac-DOTATOC, without any significant adverse effects even after 10 cycles of ß-emitter peptide receptor radionuclide therapy followed by α-peptide receptor radionuclide therapy.
