What is Radioembolization liver cancer?
Radioembolization is a minimally invasive procedure that combines embolization and radiation therapy to treat liver cancer. Tiny glass or resin beads filled with the radioactive isotope yttrium Y-90 are placed inside the blood vessels that feed a tumor.
What is sirtex treatment?
Search Sirtex US Selective Internal Radiation Therapy using SIR-Spheres® Y-90 resin microspheres enables radiation, which is often used to treat cancer, to be delivered directly into the liver tumors by using the tumor’s own blood supply.
How successful is the SIRT procedure?
In recent studies, SIRT was most effective in minimizing the risk of tumour progression in the treated lobe and had more of an effect on total liver volume, making it a more suitable modality for selected patients with substantial unilateral disease burden.
What is microsphere therapy?
About SIR-Spheres microspheres. SIR-Spheres® Y-90 resin microspheres are tiny radioactive ‘beads’ used in selective internal radiation therapy (SIRT), sometimes referred to as Y-90 radioembolization, and are used for the treatment of stage IV colon cancer that has spread to the liver and can’t be surgically removed.
What are side effects of radioembolization?
Many people experience symptoms of fatigue, nausea, abdominal pain, fever, and loss of appetite after radioembolization. These effects are usually mild or moderate, and most people leave the hospital within a day or two after the procedure. Radioembolization has a low rate of serious side effects.
Is radioembolization a surgical procedure?
Radioembolization also known as selective internal radiation therapy (SIRT), is a form of radiation therapy used to selected patients who are not candidates for surgery due to the location of their tumors or their performance (health) status.
What are SIR spheres made of?
SIR-Spheres microspheres contain resin based microspheres with an average diameter between 20 and 60 micrometre. The microspheres are impregnated with 90Y, a beta radiating isotope of yttrium with a half-life of 64.1 hours.
Is SIRT painful?
Side effects of Selective Internal Radiation Therapy (SIRT) are usually mild. You may have pain in your abdomen or nausea for 1-2 days. You also may have a raised temperature, chills or a feeling of pressure in the abdomen. These side effects are usually gone in a few days.
What are the side effects of SIRT?
How Radioembolization is done?
Radioembolization combines embolization with radiation therapy. This is done by injecting small beads (called microspheres) that have a radioactive isotope (yttrium-90 or Y-90) attached to them into the hepatic artery.
What happens after Y-90?
The most common side effect after Y-90 radiotherapy is fatigue. This can be mild or severe. It can last up to a few weeks. Other side effects include: • Poor appetite • Mild abdominal pain • Slight fever • Nausea These symptoms should slowly go away over 1 to 2 weeks.
Is radioembolization covered by Medicare?
Medicare coverage guidance is not available in the health plan’s service area for radioembolization for indications other than liver tumors, transarterial embolization (TAE) or transarterial chemoembolization (TACE). Therefore, the health plan’s medical policy is applicable.
What are Sirtex SIR-Spheres?
Search Sirtex US. SIR-Spheres ® Y-90 resin microspheres are tiny radioactive ‘beads’ used in selective internal radiation therapy (SIRT), sometimes referred to as Y-90 radioembolization, and are used for the treatment of stage IV colon cancer that has spread to the liver and can’t be surgically removed.
What is yttrium-90 (90 y) radioembolization?
Yttrium-90 ( 90 Y) radioembolization is a catheter-based therapy that delivers internal radiation to hepatic tumors in the form of microspheres. 90 Y can be delivered to the hepatic tumor as either a constituent of a glass microsphere, TheraSphere ®, or as a biocompatible resin-based microsphere, SIR-Spheres ®.
What is selectselective internal radiation therapy (SIRT)?
Selective Internal Radiation Therapy (SIRT), also known as Radioembolization, is a liver-directed therapy for inoperable liver tumors.
What does SIRT stand for in radiology?
About SIRT. Selective Internal Radiation Therapy (SIRT), also known as Radioembolization, is a liver-directed therapy for inoperable liver tumors. SIRT is administered by a specially trained Interventional Radiologist.
