Homologous Recombination Repair Defect May Predict Treatment Response to Peptide Receptor Radionuclide Therapy for Neuroendocrine Tumors

Peptide 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)...

Joint guidance on peptide receptor radionuclide therapy in neuroendocrine tumors.

A practical guidance document on peptide receptor radionuclide therapy (PRRNT) in neuroendocrine tumors is being published this month in the European Journal of Nuclear Medicine and Molecular Imaging (1). This document is the result of close collaboration among experts in the field of PRRNT from the International Atomic Energy Agency; the Radionuclide Therapy, Oncology, Dosimetry, and Radiophar...

Dose response of pancreatic neuroendocrine tumors treated with peptide receptor radionuclide therapy using 177Lu-DOTATATE.

UNLABELLED Peptide receptor radionuclide therapy (PRRT) is a promising treatment for patients with neuroendocrine tumors, giving rise to improved survival. Dosimetric calculations in relation to PRRT have been concentrated to normal organ dosimetry in order to limit side effects. However, the relation between the absorbed dose to the tumor and treatment response has so far not been established....

Developmental 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 ...
