TheraSphere® for Colorectal Cancer
Cancer Treatment Centers of America (CTCA) facilities are among the few cancer hospitals in the United States offering TheraSphere® for colorectal cancer that has metastasized to the liver. If you have been diagnosed with metastatic colorectal cancer, TheraSphere® may offer a potentially less toxic treatment option compared to chemotherapy or standard radiation.
A highly innovative new outpatient treatment, TheraSphere® uses tiny glass beads called microspheres to deliver radiation directly to tumors in the liver. Measuring just one-third the diameter of a human hair, the microspheres are embedded with a radioactive element to target colorectal cancer cells that have spread to the liver.
TheraSphere® delivers these tiny microspheres through a catheter that is positioned in the hepatic artery (the liver’s main blood vessel), targeting the microspheres directly to the tumor's blood supply. Once in the liver, the microspheres get trapped in the small blood vessels that feed the tumor. This allows radiation to be concentrated directly to the metastatic colorectal cancer tumor, while at the same time sparing surrounding healthy tissue.
