Radioembolization, also known as selective internal radiation therapy (SIRT), is a minimally invasive procedure used to treat certain types of cancer, particularly liver tumors. It involves delivering tiny radioactive beads, called microspheres, directly to the tumor site. These microspheres are injected into the hepatic artery, the main blood vessel supplying the liver. The microspheres lodge in the small blood vessels of the tumor, where they emit radiation, killing cancer cells. The procedure is performed by interventional radiologists. Before the treatment, a diagnostic angiogram is performed to map the blood vessels supplying the tumor and to identify any vessels that might lead to other organs, ensuring the radiation is targeted precisely. The radioactive isotopes commonly used include Yttrium-90. Radioembolization can be used as a primary treatment, as a bridge to transplantation, or to control tumor growth when other treatments are not feasible. It is often considered for hepatocellular carcinoma and unresectable liver metastases from colorectal cancer. The procedure typically requires a short hospital stay, and recovery involves managing potential side effects such as fatigue, nausea, and abdominal pain.
