Safety and Effectiveness of Eye90 Microspheres in the Treatment of Unresectable HCC and mCRC

The purpose of this study is to evaluate the safety of treatment with Eye90 microspheres in patients with unresectable Hepatocellular Carcinoma (HCC) and metastatic Colorectal Cancer (mCRC). Both cause tumors, known as malignant hyper-vascular hepatic neoplasia, that have an abnormally large number of blood vessels attached to them. Eye90 is internal radiation brachytherapy for treatment of malignant hyper-vascular hepatic neoplasia that uses microspheres, tiny glass beads smaller in diameter than a human hair, to provide radiation. The microspheres contain Yttrium-90 (Y90) as the radiation source, which are used to to kill cancer cells and shrink tumors. The microspheres are also radiopaque, which means that they can be seen during imaging procedures. The visibility of the microspheres allows the study doctor to confirm the microspheres have been delivered in the tumor; this may help to improve the outcome of treatment.
