Primary plasma cell leukemia (pPCL) is a rare and aggressive variant of multiple myeloma (MM) with poor long-term survival after cytotoxic chemotherapy. Many novel drugs have revolutionized the treatment algorithms for MM. The impact of targeted therapy, both pre- and post-autologous stem cell transplant (auto-HCT) remains an area of ongoing interest. In this study, we report outcomes post auto-HCT for pPCL and the impact of maintenance therapy posttransplant with novel agents.
