Radioembolization (TARE)

Radioembolization (Yttrium-90) is very similar to chemoembolization but with the use of radioactive microspheres. This is a newer and innovative technique combines embolization with radiation therapy. This is done by injecting small radioactive glass-beads (called microspheres) into the hepatic artery. This therapy is used to treat unresectable (inoperable) liver cancer, and cancers that metastasize to the liver from other parts of the body, such as the colon, lungs, breast or pancreas. This treatment is frequently used in patients with multiple liver tumors. Radioembolization is a palliative, not a curative, treatment-but patients benefit by extending their lives and improving their quality of life. Microspheres radiation therapy is delivered to a tumor through a catheter that the physician guides into the hepatic artery, the liver’s main blood vessel. The physician then inserts the microspheres directly through the catheter into the tumor’s blood supply. Once infused, the beads lodge in the blood vessels near the tumor, where they give off small amounts of radiation to the tumor site for several days. This radiation travels a very short distance, so its effects are limited mainly to the tumor.

Radioembolization requires two short visits to the hospital. The first procedure is 2-3 hours and is aimed at decreasing complications. This procedure entails “mapping” out the anatomy of the arteries to the liver by injecting contrast in the liver arteries through a catheter from the groin. Any arteries that are not feeding directly to the liver are blocked with tiny coils to prevent the radioactive beads from floating to areas outside the liver. During the first procedure a “test dose” of radiation is directly infused into the liver artery that does not injure the tumor or the liver, but it assures the radiation does flow into the tumor and remains there. If the “test dose” of radioactive beads flow through the tumor and into the body, this test will demonstrate it. Approximately one week after the first “mapping” procedure and test radiation dose, the treatment dose of radiation is given. Neither requires a long recovery or bed rest, at home or in the hospital. There are fewer side effects from this treatment compared to standard cancer treatments, with the main one being fatigue for seven to 10 days. Radioembolization is not right for every patient. For example, patients with poor liver function or cancer outside of the liver might not be candidates for this procedure.
