Multiple myeloma : recent progress in diagnosis and treatment.
Multiple myeloma (MM) has been the most intractable hematological disease for many years. Recently, basic and clinical research has advanced remarkably and a new therapeutic strategy has been established. The introduction of high-dose melphalan with autologous stem-cell transplantation and the availability of molecular-targeted novel agents such as immunomodulatory drugs and proteasome inhibitors have dramatically changed the treatment strategies for MM. Achievement of a high response rate resulted in the extension of overall survival, but further research and the development of more multimodality therapeutic approaches is warranted to cure this disease.
