High-dose chemotherapy and radiation therapy with stem cell rescue

High-dose chemotherapy and radiation therapy are given to kill any cancer cells that may regrow and cause the cancer to come back. Healthy cells, including blood-forming cells, are also destroyed by the cancer treatment. Stem cell rescue is a treatment to replace the blood-forming cells. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient and are frozen and stored. After the completion of chemotherapy and radiation therapy, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells.
