Why is yttrium 90 used for radiotherapy?

In Y-90 radiotherapy, millions of tiny radioactive beads are injected directly into the arteries that supply blood to your tumor. These beads will stay in the blood vessels around your tumor(s). This allows very strong radiation to reach the tumors directly.

How long can you live with palliative radiotherapy?

Results: Of the analyzed 963 patients who received palliative radiotherapy, 2.4% (n = 23) survived at least 5 years, with a large majority of these surviving patients (73.9%, n = 17) being free of disease.

What is the #1 side effect of radiation therapy?

The most common early side effects are fatigue (feeling tired) and skin changes. Other early side effects usually are related to the area being treated, such as hair loss and mouth problems when radiation treatment is given to this area. Late side effects can take months or even years to develop.

Patients generally resume normal activities within one or two weeks. Y90 treatment can be used in combination with traditional treatments for cancer, including surgery, chemotherapy, and immunotherapy.

How long does Y-90 last?

The radiation from yttrium-90 continually decreases over a two-week period and disappears after 30 days. The tiny microspheres remain in the liver without causing any problems.

Is radiation therapy a last resort?

Whole-brain radiation therapy (WBRT) is the treatment of last resort in the management of brain metastasis.

How many times can you get Y90?

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. “He could potentially have that multiple times to prolong his survival and keep him doing well,” Dr. McBride says.

Does Radioembolization with Yttrium-90 (90Y) microspheres cause ischemia?

Image guided targeted therapies have established their role in management of primary and secondary hepatic malignancies. Radioembolization with yttrium-90 (90Y) microspheres is safe and efficacious for treatment of hepatic malignancies. The tumoricidal effect of radioembolization is predominantly due to radioactivity and not ischemia.
