Optimization of Radioembolic Effect with Extended-shelf-life Yttrium-90 Microspheres: Results from a Pilot Study

The results demonstrate the safety and efficacy of extended-shelf-life 90Y glass microspheres. The increased embolic load and lowered activity per microsphere theoretically resulted in better tumor coverage and, hence, improved response rates. This standardizable treatment paradigm provides a minimally embolic therapy for liver tumors.
