Therapeutic options for patients with myeloma have radically changed over the past ten years. Beginning with the advances in therapy resulting from the use of high dose therapy and autologous bone marrow or stem cell transplant, we have more than doubled the median survival for patients as a whole, and have now a wealth of different biology based treatment approaches for our patients in all disease stages. The purpose of this book is to update the various treatment options for patients with myeloma, as well as to focus on the emerging and speculative aspects of myeloma therapy. This will require review of basic mechanisms of disease as well as further discussions on how these mechanisms can best be targeted. While there will be text covering most areas of myeloma therapy, the prime focus of the book will be the novel agents currently in testing as well as potential future novel targets and agents.
