Radioisotope Therapy

Radioisotope therapy is a targeted therapy. Radioisotopes are delivered through the bloodstream or orally through ingestion. The Radioisotopes commonly used in the Radiation department here are Iodine-131 and Strontium-89. Iodine-131 is used to treat thyroid cancer. The therapy is usually given by mouth (liquid or capsules). The Iodine-131 is ingested, and it is concentrated in the thyroid cells, killing the cancer cells. If the dose is low enough the patients treatment is given as an outpatient. Strontium-89 is used to treat bone metastasis, usually from prostate cancer. The isotope travels to the areas of damaged bone. This procedure is also done as an outpatient.
