Preoperative Y-90 Radioembolization for Tumor Control and Future Liver Remnant Hypertrophy in Patients With Colorectal Liver Metastases

This study is testing a liver treatment called Y-90 radioembolization (tiny radioactive beads injected into liver blood vessels) to help shrink colorectal cancer that has spread to the liver and to grow enough healthy liver tissue so that surgery becomes possible. **You may be eligible if...** - You have colorectal cancer that has spread to the liver but not elsewhere - Your liver tumors are currently too large to remove safely, but surgery might be possible after treatment - You have received at least 4 cycles (or 2 months) of chemotherapy - You are in good enough health to undergo surgery **You may NOT be eligible if...** - Your cancer has spread beyond the liver - You have severe liver disease or inadequate liver function - You are not a candidate for surgery even after treatment Talk to your doctor to see if this trial is right for you.
