We report here the 12-year survival after the first peptide receptor radionuclide therapy (PRRT) of a patient with metastatic rectal neuroendocrine neoplasms, who received 7 cycles of PRRT with Lu/Y-DOTATATE/DOTATOC in 4 treatment phases. The patient demonstrated excellent response to each cycle of treatment, without any adverse effect even after repeated PRRT cycles. Most recently, immunohistochemistry revealed a G3 neuroendocrine neoplasm and intraspinal metastasis were successfully resected by neurosurgical intervention. This case nicely demonstrates that several "salvage" PRRTs can be given over many years leading to repetitive benefit for the patient and saving patients of possible toxicity of alternative treatments.
