What is a sirt?
What is SIRT? SIRT is a radiation treatment for cancer. In this procedure, a radiation source called yttrium-90 is administered in small beads delivered through the blood stream into the organ affected by cancer.
How does the procedure work?
Once this is done, a catheter (small tube) is placed inside a blood vessel that goes directly to the organ affected by cancer. The interventional radiologist will guide the catheter close to the tumour and then will administer the specially prepared beads that contain the radiation. When the beads land in the tumour, they emit a form of radiation energy that kills the cancer cells over a short distance around the bead.

What is SIRT radiation?
SIRT generally involves a single delivery of 90yttrium micro-spheres into the hepatic artery. Preferential uptake is achieved into liver tumours, because of their predominant hepatic arterial blood supply. Average tumour doses of radiation in excess of 200 Gy are achieved.
What is SIRT in medical terms?
Selective internal radiation therapy (SIRT): a new modality for treating patients with colorectal liver metastases
How long does it take to administer stret?
SIRT is typically performed under light sedation with intravenous narcotic analgesia. Administration itself is straightforward and takes about 15 minutes, during which time the microspheres are gently flushed into the hepatic artery in a total volume of approximately 50 ml sterile water. Following the procedure patients are returned to their room and may stay in hospital for 24–48 hours. No special radiation safety precautions are necessary because the radiation is βin nature and is contained within the body. Decay takes place over the next 3 weeks, without hazard to family or friends.
What are the options for the management of colorectal liver metastases?
Operative techniques and the knowledge to support liver resection 1have developed alongside a number of ablative methods for the management of non-resectable liver metastases including cryotherapy 2 , radiofrequency ablation 3and laser electrocoagulation 4. Regional chemotherapy has been extensively used and promoted by many centres 5,6. At the same time a number of modalities that received attention in the 1970s and 1980s, including devascularising techniques, have faded from usage 7.
How much radiation is delivered to liver tumours?
The delivery of currently recommended doses of 90yttrium microspheres leads to average calculated doses of radiation in excess of 150 Gy being delivered to liver tumours, while average doses received by unaffected liver parenchyma are of the order of 20–25 Gy 16,17. Problems of clinically detected radiation hepatitis are rare.

What is the liver in radiation therapy?
Radioembolization combines the localized delivery of radiation therapy in the form of tiny beads and embolization to treat patients with liver cancer. The liver is unique because it has two blood supplies—the hepatic artery and the portal vein. The normal liver receives about 75 percent of its blood supply through the portal vein ...
Why is Y-90 used for liver cancer?
Because the liver is extremely sensitive to radiation damage, this highly precise method of delivering radiation to liver tumors makes it possible for patients with liver cancer to be treated in such a way without causing significant damage to the healthy liver tissue. Such Y-90 SIRT therapy has been shown through many clinical studies conducted worldwide to help extend the lives of patients with inoperable tumors and improve their quality of life.
