Y90 Therapy

MVHS Medical Imaging offers SIR-Spheres Yttrium-90 (Y-90) liver-directed therapy as an adjuvant therapy with chemotherapy in patients with unresectable colorectal cancer liver metastases. Y-90 uses resin microspheres treatment as a therapy to directly target liver tumors as a supplement to chemotherapy.

SIR-Spheres Y-90 resin microspheres are microscopic radioactive spheres that are delivered by the millions directly into the tumor site using a catheter advanced to the liver through the hepatic artery. While chemotherapy manages systemic disease, Y-90 microspheres specifically target the liver and are often used in combination with chemotherapy. Y-90 is sometimes referred to as “selective internal radiation therapy” or SIRT. This selective approach to treating liver tumors minimizes damage to healthy liver tissue.

According to the American Cancer Society, at least 60 percent of the nearly 140,000 Americans diagnosed with colorectal cancer every year will see their cancer spread to the liver. The liver is the most important organ to protect in patients with metastatic colorectal cancer, with a very high percentage of patients dying from liver failure. Microspheres therapy has emerged as a treatment option for patients with cancer that has spread to the liver.
