SIRT – Selective
Internal Radiation Therapy (SIRSpheres)
A revolutionary treatment for advanced liver cancer that
utilizes new technologies designed to deliver radiation directly
to the tumor site. The targeted nature of SIRT effectively
delivers up to 40 times more radiation to liver tumors than
is possible using conventional radiotherapy. The SIRT process
increases the effectiveness of tumor treatment while minimizing
harmful side effects to surrounding healthy tissue.
SIRT involves the delivery of millions of microscopic radioactive
spheres called SIRSpheres, directly to the site of the liver
tumor. SIRSpheres are approximately 35 micron in diameter
biocompatible YTTrim-90 micro-spheres that are emitting radioactive
beta radiation. The SIRSpheres are injected through a trans-femoral
catheter into the hepatic artery. The spheres lodge in the
small blood vessels of the tumor. The spheres irradiate the
tumor thus destroying the cancer tumors while most of the
normal liver tissue remains relatively unaffected.
