Y-90 Radioembolization for liver cancer
Y-90 Radioembolization (also called Selective Internal Radiation Therapy) is an advanced, minimally invasive treatment for liver cancer. It delivers precise, internal radiation directly to the tumor while sparing surrounding healthy tissue.
How does Y-90 Radioembolization work?
Patients undergoing a Y90 procedure will receive a hepatic angiogram (imaging test) prior to surgery. This involves inserting a catheter through a blood vessel in the groin and guiding it to the blood vessels that supply the liver. Contrast dye is injected to visualize the blood vessels and identify the tumor feeding vessels.
Once the blood vessels feeding the tumor are identified, the Interventional Radiologist will map out the procedure plan to determine the appropriate dosage and activity level of the Y90 microspheres, small radioactive particles, to be administered.
During the procedure, the Y90 microspheres are injected through a catheter into the target blood vessels, lodging themselves into the tumor, and releasing a high dose of radiation to kill cancer cells.
After their injection, the catheter is removed, and pressure is applied to the insertion site to minimize bleeding. Following a few hours of observation, the patient is discharged.
Benefits of Y-90 Treatment:
Y-90 therapy provides a highly targeted way to treat liver tumors without surgery. Because the radiation acts locally, side effects are significantly reduced compared to external radiation. Patients often experience improved symptoms, reduced tumor size, and in some cases, the ability to undergo additional treatment such as surgery or transplantation. Recovery is typically quick, with most patients resuming normal activities within days.
