Abstract
Treatment of multiple myeloma (MM) has evolved remarkably over the past few decades. Autologous stem cell transplantation, as well as proteasome inhibitors, immunomodulatory drugs, and monoclonal antibodies, has substantially improved the prognosis of patients with MM. Novel therapies, including chimeric antigen receptor-T cells, bispecific T-cell engagers, antibody-drug conjugates, histone deacetylase inhibitors, and nuclear export inhibitors, have provided more options. However, MM remains incurable. T cells are the principal weapons of antitumor immunity, but T cells display a broad spectrum of dysfunctional states during MM. The promising clinical results of T-cell-directed immunotherapies emphasize the significance of enhancing T-cell function in antimyeloma treatment. This review summarizes the potential effects of these antimyeloma agents on T-cell function and discusses possible optimized strategies for MM management by boosting T-cell immunity.
