Treatment for multiple myeloma (MM) has changed beyond recognition over the past two decades. During the early 1980s, MM inevitably resulted in a slow progressive decline in quality of life until death after about 2 years, while today patients can expect a 50% chance of achieving a complete remission, median survival of 5 years, and a 20% chance of surviving longer than 10 years. An international expert opinion meeting (including members of the GIMEMA and DSMM study groups) was held in 2009. One of the outcomes of the meeting was the development of a consensus statement outlining contemporary optimal clinical practice for the treatment of MM. The international panel recommended that the state of the art therapy for MM should comprise: (a) evidence-based supportive care, (b) effective and well-tolerated chemotherapeutic regimens, (c) autologous hematopoietic stem cell transplant (ASCT) for patients suitable for intensive conditioning therapy, and (d) evidence-based incorporation of novel anti-MM agents. Maintenance strategies have also become increasingly important for the prolongation of remission after front-line therapies. In addition, improved understanding of the biology of MM has led to the development of novel biological therapeutic agents such as thalidomide, lenalidomide, bortezomib, and others. These agents specifically target intracellular mechanisms and interactions, such as those within the bone marrow microenvironment, and have been integrated into MM treatment. This report reviews recent clinical advances in the treatment strategies available for MM and provides an overview of the state of the art management of patients with MM.

Over the past two decades, not only treatment options, but also the diagnosis, staging, and risk assessment of multiple myeloma (MM), have undergone significant development, partially due to a deeper understanding of MM pathogenesis. Conventional cytogenetics and fluorescence in situ hybridization are routinely assessed in MM, and when combined with ISS stage may attain an even better predictive potential. In order to achieve even more effective and individualized therapies, one crucial goal is the identification of genes and gene combinations that predict for response or resistance to chemotherapy. High-dose chemotherapy with autologous stem cell transplant (SCT) still remains the standard therapy for younger patients, with novel agents now being included in both pre-transplant regimens and post-transplant consolidation/maintenance approaches. Similarly, novel agents are also being incorporated into allogeneic SCT for selected patients. In the treatment of elderly patients with MM, novel agents have been successfully incorporated into less intensive regimens, including melphalan/prednisone, low-dose dexamethasone, and cyclophosphamide/dexamethasone. While second-generation proteasome inhibitors are currently being intensively investigated, the subcutaneous administration of bortezomib, being equivalent to the established i.v. route, is now entering clinical practice. Supportive care remains a crucial aspect in the management of MM. The European Myeloma Network Trialist Group aims to address these contemporary aspects in MM.
