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),
