Overview

177Lu-PRRT (Lutetium-177 Peptide Receptor Radionuclide Therapy) is a targeted radiopharmaceutical therapy primarily used for the treatment of somatostatin receptor (SSTR)-positive neuroendocrine tumors (NETs). The therapy involves a radioactive isotope, Lutetium-177, conjugated to a somatostatin analog peptide (such as DOTATATE or DOTATOC) that binds with high affinity to SSTRs overexpressed on tumor cells. Upon binding, the radiopharmaceutical is internalized, and the Lutetium-177 emits beta radiation, which causes localized DNA damage and cell death within the tumor while minimizing radiation exposure to healthy tissues. It is an established systemic treatment for metastatic or inoperable NETs, with the most prominent commercial version being Lutathera (lutetium Lu 177 dotatate).
