Multiple myeloma (MM) remains incurable despite advances in treatment options. Although tumor subtypes and specific DNA abnormalities are linked to worse prognosis, the impact of immune dysfunction on disease emergence and/or treatment sensitivity remains unclear. We developed an Immune Atlas of MM by generating profiles of 1,397,272 single cells from the bone marrow (BM) of 337 newly diagnosed participants and characterized immune and hematopoietic cell populations. Cytogenetic risk-based analysis revealed heterogeneous associations with T cells of BM, with 17p13 deletion showing distinct enrichment of a type 1 interferon signature. The disease progression-based analysis revealed the presence of a proinflammatory immune senescence-associated secretory phenotype in rapidly progressing participants. Furthermore, signaling analyses suggested active intercellular communication involving a proliferation-inducing ligand and B cell maturation antigen, potentially promoting tumor growth and survival. Lastly, using independent discovery and validation cohorts, we demonstrated that integrating immune cell signatures with known tumor cytogenetics and individual characteristics significantly improves stratification for the prediction of survival.
