Multiple myeloma

Multiple myeloma (MM) is a malignancy of the plasma cell characterized by migration and localization to the bone marrow where cells then disseminate and facilitate the formation of bone lesions. Unfortunately, while treatment of this disease is effective in palliating the disease, and even prolonging survival, this disease is generally regarded as incurable. Understanding the basic biology of myeloma cells will ultimately lead to more effective treatments by developing target based therapy. In Section I, Dr. Bergsagel discusses the molecular pathogenesis of MM and shares insights regarding specific chromosomal translocations and their role in the genesis and progression of MM. New information regarding FGFR3 as an oncogene as well as how activating mutations may contribute to disease evolution and may be an important target for novel therapeutics of MM is presented. In Section II, Dr. Anderson elaborates on novel therapeutic approaches to MM also targeting fundamental genetic abnormalities in MM cells. Both preclinical and clinical studies of novel agents including PS-341 and IMiDs are highlighted. In Section III, Dr. Harousseau discusses the role of autologous stem cell transplant in MM. He highlights clinical trials addressing the question of conditioning regimens and the impact of tandem transplants. He also addresses the role of allogeneic BMT and the use of attenuated dose conditioning regimens (so called mini-allogeneic transplants) in the treatment of MM. In Section IV, Dr. Dalton provides an overview of the current state of myeloma therapy and summarizes the different and exciting approaches being undertaken to cure this disease.
