Introduction This booklet explains important details about the transplant of blood stem cells. Questions addressed include: n What are blood stem cells? nW hy are blood stem cells collected and used for transplant? nW hat are the benefits and risks of high-dose chemotherapy with blood stem cell rescue as part of the treatment for myeloma? nW hat is the role of high-dose chemotherapy versus novel therapies? Can they be used in combination? The booklet is meant to provide you with gen- eral information only. It is not meant to replace the advice of your doctor, nurse, or other healthcare practitioners. Your healthcare team can answer specific questions related to your personal treatment plan. All words that appear in bold type are defined in the glossary at the back of this booklet. What is Multiple Myeloma? Multiple myeloma (also known as myeloma and plasma cell myeloma) is a cancer of the immunoglobulin-producing plasma cells found in the bone marrow. It is a cancer that involves the immune system. The cancerous plasma cells, or myeloma cells, rarely enter the blood stream. The myeloma cells accumulate in the bone marrow, causing the following: nD isruption of normal bone marrow function, most commonly causing anemia (a low level of red blood cells in the bloodstream), 4 5

Growth factors are often used for patients receiving chemotherapy to hasten their white and red cell count recovery. The white cell growth factors (Neupogen, Neulasta, Leukine) used in high doses stimulate the release of stem cells from the bone marrow into the blood- stream. This process is called “mobilization.” The injections are given daily for three or more days. Stem cells are usually collected on the 4th 16 17

The transplant takes place in the patient’s room: it is not a surgical pro- cedure. The frozen bags of bone marrow or blood cells are thawed in a warm water bath, and then injected into the bloodstream through the catheter. Upon thawing, the DMSO (freez- ing agent) evaporates into the air and creates a distinct and somewhat unpleasant garlic smell. Most centers infuse one bag at a time.
