Abstract: Peptide receptor radionuclide therapy (PRRT) specifically uses radiolabeled peptides as biological targeting vectors designed to deliver cytotoxic levels of radiation dose to cancer cells that overexpress specific receptors. In recent years, how to further improve the efficacy of radiotherapeutic drugs for PRRT has been an international research hotspot.The peptides with Evans blue motif, uses endogenous albumin as a reversible carrier to effectively extend the half-life in the blood and substantially increase targeted accumulation and retention within the tumor to achieve better efficacy. This review focuses on the clinical translational research of Evans blue modified peptides used for theranostics.
