• Longitudinal Analysis of Therapy and Microenvironment in Multiple Myeloma

    Multiple myeloma (MM) is a bone marrow resident plasma cell malignancy that causes clinical manifestations including hypercalcemia, renal dysfunction, anemia and osteolytic bone lesions. To study the immune and hematopoietic abnormalities across disease and treatment, we generated and analyzed longitudinal multi-omic profiling of matched bone marrow and peripheral blood from MM patients across diagnosis, induction, autologous stem cell transplant (ASCT), and recovery.

    Findings Highlight:

    Over the course of the study, 13.3% of the patients progressed, whereas 66.7% achieved a complete or stringent complete response, and 60% improved their response over the course of therapy. We also identified persistent immune dysfunction obscured by patient heterogeneity. We found the tumor imposes a compartment-specific immune program where the marrow exhibits metabolic and inflammatory changes that bias hematopoiesis and alter cytotoxic effector programs not mirrored in blood, with adaptive immune reconstitution impaired up to two years post-ASCT. These findings define how myeloma and its treatment durably reshape immunity from the marrow outward.
