This animated Mode of Action video has been created by Sirtex Medical to serve as an educational resource that provides a narrative look at Selective Internal Radiation Therapy (SIRT) using SIR-Spheres® Y-90 resin microspheres. SIRT using SIR-Spheres microspheres is a targeted liver tumor treatment that delivers millions of radioactive microspheres directly to inoperable liver tumors. SIR-Spheres Y-90 resin microspheres are the only fully FDA-approved microsphere radiation therapy for the treatment of colorectal liver metastases. This video covers explanation and animation of the SIR-Spheres® Y-90 resin microspheres procedure.

SIRT, also known as radioembolization, is a proven technology for inoperable liver cancer that delivers doses of radiation directly to the site of tumors. In a minimally invasive treatment, millions of radioactive SIR-Spheres microspheres are infused via a catheter into the liver where they selectively target liver tumors with a dose of internal radiation up to 40 times higher than conventional radiotherapy, while sparing healthy tissue.
Clinical studies have confirmed that patients with metastatic colorectal cancer treated with SIR-Spheres microspheres have response rates higher than with other forms of treatment, resulting in increased life expectancy, greater periods without tumor activity and improved quality of life. SIRT has been found to shrink liver tumors more than chemotherapy alone.
SIR-Spheres microspheres are approved for use in Australia, the United States of America (FDA PMA approval), the European Union (CE Mark) and Argentina (ANMAT). Additionally, SIR-Spheres microspheres are supplied in countries such as Hong Kong, Malaysia, Singapore, Thailand, Taiwan, India, Israel, and Turkey. Available at more than 600 treatment centers, over 34,000 doses of SIR-Spheres microspheres have been supplied worldwide.
