Definition

A radioactive drug used to treat adults and children aged 12 years and older with gastroenteropancreatic neuroendocrine tumors that are somatostatin receptor positive. It is also being studied in the treatment of other types of cancer. Lutetium Lu 177-dotatate binds to a protein called somatostatin receptor, which is found on some neuroendocrine tumor cells. Lutetium Lu 177-dotatate builds up in these cells and gives off radiation that may kill them. It is a type of radioconjugate and a type of somatostatin analog. Also called Lutathera.
