abstract = {The bone marrow microenvironment plays a crucial role in
the development of multiple myeloma. As the disease
progresses, malignant myeloma cells can evolve to survive
outside the bone marrow. However, the processes underlying
bone marrow independence and their consequences for immune
control remain poorly understood. Here, we conducted
single-cell and spatial multiomics analyses of bone
marrow-confined intramedullary disease and paired breakout
lesions that disrupt the cortical bone. These analyses
revealed a distinct cellular microenvironment and
architectural features of breakout lesions, characterized by
extensive areas of malignant plasma cells interspersed with
lesion-specific solitary natural killer and macrophage
populations, as well as focal accumulations of immune cell
agglomerates. Within these agglomerates, spatially confined
T cell clones expanded alongside various immune cells,
coinciding with the local genomic evolution of tumor cells.
These analyses identify breakout lesions as a hotspot for
tumor-immune cell interactions and diversification,
representing a key event in myeloma pathogenesis.},
