What Is Y90 Radioembolization (Y90 Treatment for Liver Cancer)?
Y90 radioembolization is a minimally invasive treatment for liver cancer that combines embolization and targeted radiation therapy, without the need for open surgery. Embolization refers to the delivery of tiny particles into specific blood vessels using advanced imaging guidance. These particles are used to block blood flow and deliver treatment directly to tumors. Radiation is energy emitted by certain materials that can destroy cancer cells.
During the procedure, an interventional radiologist delivers microscopic radioactive beads, known as Y90 microspheres, into the arteries supplying the liver. These beads travel through the blood vessels and become lodged within the tumor. Once in place, they emit radiation that destroys nearby cancer cells. The radiation travels only a few millimeters, which helps protect surrounding healthy liver tissue.
Y90 radioembolization is one of the most extensively studied and effective liver cancer treatments available. It allows radiation to be delivered precisely where it is needed and has been successfully performed on thousands of patients worldwide. This treatment is also known as radioembolization, transarterial radioembolization (TARE), or selective internal radiation therapy (SIRT).
Why Is Y90 Radioembolization Needed?
Some liver tumors cannot be removed surgically, leaving patients with limited treatment options. In addition, liver cancer typically requires prompt treatment for the best outcomes. External beam radiation is often not suitable for liver tumors because it can damage healthy liver tissue.
Y90 radioembolization was developed as a targeted solution that delivers radiation directly to liver tumors while minimizing harm to normal liver tissue. This approach allows doctors to treat tumors that are otherwise difficult or impossible to manage with surgery or traditional radiation therapy.
Advantages
- Minimally invasive treatment with no open surgery required
- Targets liver tumors directly while preserving healthy liver tissue
- Suitable for patients who are not candidates for surgery or external radiation
- Short recovery time compared to traditional surgical treatments
- May improve survival rates and quality of life
FAQ
1. Am I a Candidate for Y90 Radioembolization??
Y90 radioembolization may be an appropriate treatment option for patients with liver cancer, particularly those who have not responded to other therapies. A thorough evaluation is required, including a consultation with a board-certified interventional radiologist.
Testing may include imaging studies such as CT scans or MRI, along with blood tests to assess liver and kidney function.
Y90 can be used to treat primary liver cancers, such as hepatocellular carcinoma and cholangiocarcinoma, as well as metastatic tumors that have spread to the liver from other parts of the body.
It is important to understand that Y90 is not a guaranteed cure and may not be suitable for everyone. Patients are encouraged to ask questions and fully understand the risks and benefits before proceeding.
