Management of Relapsed Multiple Myeloma after Autologous Stem Cell Transplant

Autologous stem cell transplantation (ASCT) remains a standard of care for multiple myeloma patients who are eligible to receive high-dose therapy, recognizing that the optimal timing and integration of this approach is now under study in a number of randomized trials. Despite the improved response rates with induction therapy consisting of immunomodulatory drugs and/or proteasome inhibitors, as well as the increasing use of post-ASCT maintenance therapy, most myeloma patients relapse and die of their disease. Here we discuss the options for managing post-ASCT relapse, including the role of various salvage regimens in the setting of relapsed and refractory myeloma, salvage ASCT, and salvage allogeneic SCT.
