TheraSphere is an innovative, internal radiation therapy for cancer that has spread to the liver. It targets liver tumors with microscopic glass beads containing radioactive material.
TheraSphere® Treatment for Metastatic Stomach Cancer
With advanced stage stomach cancer or recurrent stomach cancer, the disease may spread (i.e., metastasize) to the liver. In some cases, cancer in the liver is not able to be surgically removed. Depending on the extent of the cancer, liver function and other factors, one option may be to treat the disease with TheraSphere®. This highly innovative, internal radiation therapy is available at some Cancer Treatment Centers of America (CTCA) hospitals.
TheraSphere treatment uses microscopic glass beads to deliver radiation treatment to liver tumors. Measuring one-third the diameter of a human hair, the beads are embedded with a radioactive material, which aims to kill cancer cells in the liver.
The treatment is delivered through a catheter positioned in the liver’s main blood vessel. Once the beads enter the liver, they get trapped in the small blood vessels that feed the tumor. This concentrates the radiation within the tumor.
TheraSphere therapy is so targeted that it minimizes harm to healthy liver tissue. In comparison to other radiation treatments or chemotherapy, TheraSphere treatments may also be a less toxic option.
