When the radiopeptide is injected into a patient’s bloodstream, it binds to protein receptors called somatostatin receptors, located on NET cells, and delivers high doses of radiation to the tumor. Because it’s a systemic treatment, PRRT targets NETs with somatostatin receptors anywhere in the body.
