All you need to know about Peptide Receptor Radionuclide Therapy (PRRT)
Short PRRT PrimerWhat is Peptide Receptor Radionuclide Therapy (PRRT)?What is PRRT? PRRT stands for Peptide Receptor Radionuclide Therapy, an FDA-approved therapy used for systemic treatment of neuroendocrine tumors. Peptide refers to the small molecule for this therapy. The Peptide used (DOTATATE or DOTATOC or DOTANOC) is very similar to Somatostatin, a hormone which binds to receptors found on neuroendocrine tumors. Receptor refers to a specific target on neuroendocrine tumor cells that the peptide attaches to. After the peptide joins with a Receptor, it becomes attached and enters the targeted tumor cell. Radionuclide refers to radioactive atom that is attached to the peptide. As the peptide enters the cell, it brings the Radionuclide into the tumor cell. The radionuclide (e.g. lutetium-177), then decays and emits radiation within the tumor cell.Therapy refers to the idea that we are using this combination of Peptides, Receptors, and Radionuclides…
