Summary
Introduction
Modern treatment of newly diagnosed MM has led to improved responses and markedly improved survival[1,2]. However, despite excellent responses and disease control most patients will eventually relapse and require further therapy. Management of relapsed disease is therefore a critical aspect of overall care. This chapter provides a comprehensive overview of the determinants of and general approaches to therapy as well as a review of specific treatment regimens.
Definition of relapsed and relapsed/refractory MM
The European Group for Blood and Marrow Transplantation (EBMT)[3] criteria and International Myeloma Working Group (IMWG) uniform criteria[4] define progressive disease as ≥25% increase (or reappearance from complete response) in the measurable biochemical component (serum monoclonal protein, urine Bence Jones protein or Serum Free Light chain), an increase in bone marrow plasma cells to >10% or the development of new lytic bone lesions/soft tissue plasmacytomas. Clinical relapse is defined as the development of progressive disease and/or myeloma associated end organ dysfunction (CRAB criteria). Primary refractory myeloma refers to disease that fails to achieve at least a minimal response (MR) with initial therapy whilst relapsed and refractory MM is defined as disease that is non-responsive to salvage therapy, or progresses within 60 days of last treatment in patients who previously achieved at least a minimal response (MR).
