Peptide Receptor Radionuclide Therapy (PRRT) of Medullary and Nonmedullary Thyroid Cancer Using Radiolabeled Somatostatin Analogues

Published on Monday, 25 May 2020

Abstract

As therapeutic options in advanced medullary and non-iodine avid differentiated (nonmedullary) thyroid cancers are limited and associated with significant toxicity, targeting of somatostatin receptors (SSTRs) for internal radiation therapy provides a promising option.

Theranostics (therapy and diagnosis) using radiolabeled somatostatin analogues has proved to be a milestone in the management of SSTR-expressing tumors.

Peptide receptor radionuclide therapy using (177)Lu-labeled or (90)Y-labeled somatostatin analogues may have a significant role in the management of medullary and nonmedullary thyroid cancers in those patients where PET/CT with (68)Ga-labeled somatostatin analogues demonstrates significant SSTR expression.
