Radiation Therapy for Colon, Rectum and Anus Cancers

Treating Liver Metastases

Colon and rectum cancers sometimes spread to the liver.

• Liver metastases can sometimes be removed by surgery.
• When surgery is not possible, radiation therapy may be an option. A specialized external beam radiation treatment called stereotactic body radiation therapy (SBRT) can accurately target some liver tumors.
• Another treatment option is selective internal radiation therapy (SIRT), an injection of radioactive particles into the blood vessels of the liver.
• Your radiation oncologist can discuss with you which approaches are best in your case.
