TheraSphere is a treatment for colorectal cancer that has spread to the liver. This innovative, internal radiation therapy targets liver tumors with tiny radioactive glass beads called microspheres.
TheraSphere Targets Liver Tumors
Cancer Treatment Centers of America facilities are among a select number of cancer hospitals in the United States offering TheraSphere® for colorectal cancer that has metastasized (spread) to the liver. This internal radiation therapy may be a promising option if you have an inoperable tumor in the liver.
A highly-innovative outpatient colorectal cancer treatment, the TheraSphere procedure involves using tiny glass beads called microspheres to deliver radiation directly to a tumor 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 treatment is delivered through a catheter positioned in the hepatic artery (the liver’s main blood vessel). Once the microspheres enter the liver, they get trapped in the small blood vessels that feed the tumor. This allows the radiation to be concentrated within the tumor.
Because this colorectal cancer treatment is so targeted, it minimizes injury to healthy liver tissue. In comparison to standard radiation treatment or chemotherapy, TheraSphere may also be a less toxic treatment option.
