Yttrium-90 Radioembolization: An effective treatment of Metastic Liver Cancer

Interventional radiology (IR) offers many innovative and non-surgical options to diagnose many diseases, including cancer. This minimally-invasive method uses imaging guidance so that interventional radiologists can deliver much precision in the treatment. In this regard, radioembolization is one of the remarkable IR developments by which interventional radiologists can easily treat primary and metastatic liver tumors.

The radioembolization procedure delivers radiation directly to the tumor site that enables interventional radiologists to place millions of microspheres, minute particles that emit radiation, into the blood vessels feeding the tumor(s). These microspheres cut off the blood supply to the tumor and destroy cells that are inaccessible by other techniques. Yttrium-90 or Radioembolization (Y-90) is a non-surgical procedure that is used to treat liver cancer. It delivers targeted internal radiation therapy to the tumor. By this technique a catheter can be inserted through a tiny incision in the groin to reach hepatic artery. After placing it in the hepatic artery millions of beads or microspheres, containing radioactive element, yttrium-90, are released into the blood stream.

In this way Yttrium90 (y-90) radioembolization procedure whereby resin or glass coated particles incorporated with (y-90) isotopes are infused through a selectively placed intrahepatic arterial placed catheter. This highly localized technique can be used along with other treatment modalities like surgery or transplant, chemotherapy, etc. Radioembolization more sophistically addresses the common challenges associated with treatment of cancer by delivering focused radiation. And healthy tissue remains relatively unaffected. It brings new hope in curing primary and metastatic liver cancer and provides minimum recovery time and other side effects.
