Preferred Name: Yttrium Y 90-Edotreotide

Definition: A radioconjugate consisting of the octreotide derivative edotreotide labeled with yttrium 90 (Y-90) with potential radiotherapeutic uses. Similar to octreotide, yttrium Y 90-edotreotide binds to somatostatin receptors (SSTRs), especially type 2 receptors, present on the cell membranes of many types of neuroendocrine tumor cells, delivering tissue-specific, beta-emitting nuclide Y-90-mediated cytotoxicity to SSTR-positive cells. Yttrium Y 90-edotreotide is produced by substituting tyrosine for phenylalanine at the 3 position of the somatostatin analogue octreotide and chelating the substituted octreotide to Y-90 via dodecanetetraacetic acid (DOTA).

NCI-GLOSS Definition: A substance being studied in the treatment of some types of cancer. Yttrium Y 90 edotreotide contains yttrium Y 90 (a radioactive form of the metal yttrium) attached to a molecule that binds to certain types of neuroendocrine tumors (tumors that come from cells that release hormones). The radioactivity from yttrium Y 90 may kill the cancer cells.
