An exciting new liver cancer treatment offered by our group is Yttrium-90 microsphere therapy for liver tumors. A tiny catheter is threaded into the liver artery, then microscopic glass beads impregnated with a highly radioactive element are injected into the liver tumors, giving them a higher dose of radiation than can be safely delivered by external beam radiation treatment. There are only about 40 centers performing this treatment in the USA at this time, including our clinic in Illinois. This liver cancer treatment is effective against primary cancer of the liver, but new research is showing that it may be effective in treating metastatic cancer in the liver from colorectal cancer, neuroendocrine tumors, and even breast cancer. Research on this and other new liver cancer treatments is ongoing.
