[Neuroendocrine tumors: Peptide receptors radionuclide therapy (PRRT)].

Neuroendocrine tumors (neuroendocrine tumors-NET) are a heterogeneous group of neoplasms with a common embryological origin and diverse biological behavior, derived from cells of the neuroendocrine system, the system APUD (amine precursor uptake and decarboxylation). They are characterized by overexpression of all five somatostatin receptors (SSTR1-SSTR5), particularly type 2 (SST2). Surgical resection of the tumor is the treatment option, with a possibility of complete remission in patients with limited disease.
