How long does Y90 procedure take?
If there are multiple tumors, the procedure may need to be repeated in another blood vessel. The procedure takes about one hour to complete.
How long do Y90 side effects last?
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.
How effective is SIRT treatment?
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.
How many y90 treatments can you have?
Patients are typically limited to two treatments, although doctors can take another approach — only with concentrated chemotherapy and larger particles — once radiation limits are reached.
What is a SIRT procedure?
SIRT (sometimes called radioembolization) is a treatment that’s used to destroy liver tumors. During your SIRT treatment, tiny radioactive beads are sent directly to the tumor through the arteries (blood vessels) in your liver. The beads give off radiation over a very short distance.
How is embolization used in the treatment of cancer?
A minimally invasive treatment in which interventional radiologists block vessels that supply tumors with blood and deliver treatments directly to the tumor. Cancer arises when abnormal cells multiply unusually rapidly and accumulate in masses called tumors.
How long does it take to recover from radiation embolization?
The radiation travels a very short distance, so its effects are limited mainly to the tumor. Possible complications after embolization include: Sometimes, it can take 4-6 weeks to fully recover from the procedure. Because healthy liver tissue can be affected, there is a risk that liver function will get worse after embolization.
How is radioembolization used to treat liver cancer?
Radioembolization (Y90) 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 kind of radiation is used in radioembolization?
The radiation is in the form of a radioactive isotope called Yttrium-90 or Y-90, which is fixed onto tiny glass or resin particles. Once a microcatheter is placed into the artery supplying the cancer, angiography is performed to confirm appropriate position, and the radioactive microspheres are injected into the artery.
