Multiagent induction chemotherapy leads to high response rates in multiple myeloma. The phase III Southwest Oncology Group trial involving 525 patients established lenalidomide, bortezomib, and dexamethasone (RVD) as a preferred induction regimen; in this trial, RVD demonstrated an overall response rate of 81.5%, with 15.7% of responses complete responses (CR), and 27.8% very good partial responses (VGPR).[1] Nonetheless, autologous stem cell transplantation (ASCT) still is and will remain a mainstay of therapy, with 6,300 transplants done in the United States for myeloma in 2013.[2] Phase III trials continue to support the use of high-dose chemotherapy over conventional therapy, even with novel agents.
