How does PRRT work?
Most NETs have lots of receptors on their cells for a hormone called somatostatin. Octreotide is a manmade version of somatostatin, which is attracted to these receptors on the NETs. IN PRRT, the octreotide has a radionuclide attached to it. This allows the octreotide to bring the radiation right to the tumor, and not to healthy tissues.
