Metallofullerene-Nanoplatform-Delivered Interstitial Brachytherapy Improved Survival in a Murine Model of Glioblastoma Multiforme

Year: 2012

Type: article

Abstract: Fullerenes are used across scientific disciplines because of their diverse properties gained by altering encapsulated or surface-bound components. In this study, the recently developed theranostic agent based on a radiolabeled functionalized metallofullerene ((177)Lu-DOTA-f-Gd(3)N@C(80)) was synthesized with high radiochemical yield and purity. The efficacy of this agent was demonstrated in two orthotopic xenograft brain tumor models of glioblastoma multiforme (GBM). A dose-dependent improvement in survival was also shown. The in vivo stability of the agent was verified through dual label measurements of biological elimination from the tumor. Overall, these results provide evidence that nanomaterial platforms can be used to deliver effective interstitial brachytherapy.
