This book provides a concise overview of the state of the art in the biology and treatment of plasma cell malignancies, a heterogeneous group of diseases primarily characterized by the presence of clonal plasma cells within the bone marrow or extramedullary sites. The plasma cell dyscrasias investigated include monoclonal gammopathy of undetermined significance (MGUS), multiple myeloma, plasmacytoma, immunoglobulin deposition diseases (primary amyloidosis and systemic light and heavy chain deposition diseases), and Waldenstroem's macroglobulinemia. In the case of multiple myeloma, the coverage ranges from genomic aberrations and microRNAs to treatment for different patient groups, upcoming novel therapies, immunotherapy, and transplantation. The book reflects the significant research advances achieved in this field during the past few years, which have enhanced our understanding of the molecular mechanisms responsible for the pathogenesis of plasma cell dyscrasias.

Multiple Myeloma (MM) is the second most common type of blood cancer, resulting from an overproduction of cancerous infection-fighting white blood cells, known as plasma cells. Plasma cells are a crucial part of the immune system responsible for the production of antibodies. Bortezomib is a promising anticancer drug targeting the proteasome. This proteasome inhibitor induces cell stress and apoptosis in the cancer cells. While multiple mechanisms are likely to be involved, proteasome inhibition may prevent the degradation of pro-apoptotic factors, permitting activation of programmed cell death in neoplastic cells dependent upon the suppression of proapoptotic pathways. This monograph on bortezomib is a valuable source of information for researchers and clinicians from the fields of oncology and pharmacology, working either in academia or the pharmaceutical industry.
