    ABSTRACT: Lenalidomide (Revlimid®) combined with intermittent dexamethasone (the RD regimen) is one of the current standards for treatment of patients with relapsed/refractory multiple myeloma (MM). However, since the disease in the majority of patients will become resistant to RD, or treatment with RD needs to be discontinued due to side effects, we evaluated the combination lenalidomide, low-dose oral cyclophosphamide, with prednisone (REP) in patients with relapsed/refractory MM previously exposed to RD. For this purpose, we performed a single centre retrospective study of the efficacy of REP in 19 patients with relapsed/refractory MM. Overall response rate (partial response or better) with REP was 68% compared with 83% with RD, but with a shorter time to response with the triplet REP. Time to progression after REP was 6 months. Overall the REP regimen was better tolerated compared to RD. We conclude that the REP regimen is an effective treatment regimen for patients with relapsed/refractory MM with good tolerance, warranting further exploration in prospective randomized trials.

    ABSTRACT: This review summarizes the therapeutic strategies and the drugs actually in development for the management of myeloma patients. Multiple myeloma is caused by the expansion of monoclonal plasma cells and secretion of M-protein (immunoglobulins, Bence Jones protein and free light chains). Multiple myeloma still remains an incurable disease with a high incidence rate in the elderly, despite the introduction of several new therapeutic agents (bortezomib, lenalidomide and thalidomide) which have changed its natural history. The high heterogeneity of this disease leads to large differences in clinical responses to treatments. Thus, the choice of the best treatment is a difficult issue. However, the introduction of new drugs has made it possible to achieve high response rates and good quality responses with long-term disease control. Interactions between tumor cells and their bone marrow microenvironment play a pivotal role in the development, maintenance, and progression of myeloma, inducing also drug resistance. These knowledges have improved treatment options, leading to the approval of new drugs which not only target the malignant cell itself, but also its microenvironment. These agents are in preclinical/early clinical evaluation and they appear to further improve disease control, but their use is still not approved outside of clinical trials.

    ABSTRACT: New treatment options for patients with myeloma have helped to change the natural history of this disease, even in the context of relapsed disease. For standard-risk patients, doublet-based therapy may offer benefit, whereas for patients with aggressive or genetically high-risk disease combinations of agents are needed for adequate disease control. Second-generation agents offer significant activity for patients with refractory myeloma, and new categories of agents provide new targets for future study and clinical use. Combinations of these agents in selected patient populations represent the next stage in the quest to cure myeloma.
