There have been major recent advancements in the understanding and management of multiple myeloma which in turn has led to unprecedented survival outcomes for patients. Diagnostic and response criteria have been recently revised. Our understanding of clonal progression, evolution, and clonal tides will inform therapeutic choices and appropriate treatment for patients. Response rates to initial induction with modern triplet therapies containing proteasome inhibitors and immunomodulators have made this approach the global standard for initial treatment. Although the relevance of autologous transplantation has been questioned in the setting of modern induction therapy, we have new data suggesting its continued relevance. Recent studies performed in the context of novel agent induction suggest that autologous transplantation continues to improve response rates and progression-free survival, thus underscoring its role in transplant-eligible patients. Emerging paradigms in the treatment of multiple myeloma include immune approaches, such as adoptive cellular therapies, vaccines, or antibody-based immune manipulations, all of which seem to synergize with a transplant platform. Allogeneic transplantation is limited in scope by the concern of prohibitive toxicity and is applicable mainly to younger patients with high-risk disease. However, the allogeneic approach offers even more options of immunotherapy at relapse, including donor lymphocyte infusions, immunomodulatory drug maintenance, and withdrawal of immune suppression.
