Somatostatin-receptor-based imaging and therapy of gastroenteropancreatic neuroendocrine tumors.
Somatostatin receptor imaging (SRI) with [(111)In-DTPA(0)]octreotide has proven its role in the diagnosis and staging of gastroenteropancreatic neuroendocrine tumors (GEPNETs). Newer radiolabeled somatostatin analogs which can be used in positron emission tomography (PET) imaging, and which have a higher affinity for the somatostatin receptor, especially receptor subtype-2, have been developed....
متن کاملDevelopmental trends in targeted radionuclide therapy of neuroendocrine tumors
Neuroendocrine tumors (NETs) constitute a heterogeneous group of neoplasms including carcinoids, pancreatic neuroendocrine tumors, pituitary tumors, medullary thyroid carcinoma and phaeochromocytomas. The symptoms and the outcome of NETs differ considerably between patients depending on several factors. By labelling tracers with a radioisotope, the tracer acts as a ...
متن کاملPeptide receptor radionuclide therapy (PRRT) of neuroendocrine tumors with somatostatin analogues.
BACKGROUND Clinical experience with the radiolabeled somatostatin analogues 90Y-DOTATOC and, more recently, 177Lu-DOTATATE, is ongoing since more than a decade in few centers. Dosimetric studies demonstrated that 90Y-DOTATOC and 177Lu-DOTATATE are able to deliver high doses to somatostatin receptor sst2-expressing tumors and low doses to normal organs. RESULTS AND CONCLUSIONS Clinical studies...
متن کاملPeptide receptor radionuclide therapy for advanced neuroendocrine tumors.
Peptide receptor radionuclide therapy (PRRT) consists of the systemic administration of a synthetic peptide, labeled with a suitable β-emitting radionuclide, able to irradiate tumors and their metastases via internalization through a specific receptor (usually somatostatin S2), over-expressed on the cell membrane. After almost 2 decades of experience, PRRT, with either (90)Y-octreotide or (177)...
متن کاملTargeted radionuclide therapy with 90Y-DOTATOC in patients with neuroendocrine tumors.
BACKGROUND The aim of this study was to assess the efficacy and safety of targeted radionuclide therapy with [90Y-DOTA0, Tyr3]-octreotide (90Y-DOTATOC) in patients with metastatic neuroendocrine tumors. PATIENTS AND METHODS One hundred and sixteen patients with metastatic neuroendocrine tumors were included. All patients were pre-therapeutically staged with morphological imaging procedures an...
