Breast Implant-Associated Anaplastic Large Cell Lymphoma: Insights into Cellular Diversity, Immune Suppression, and Therapeutic Opportunities

Highlight

• BIA-ALCL is a heterogeneous T cell lymphoma arising in women with textured breast implants with variable gene expression profiles.

• The cell of origin is a memory CD4+ or CD8+ T cell identified by unique TCR rearrangement and gene expression patterns.

• The tumor immune microenvironment (TIME) is complex, featuring distinct myeloid populations and elevated immunosuppressive cytokines including IL-10, IL-13, and TNF.

• BIA-ALCL induces T cell exhaustion and immune evasion, revealing potential novel immunotherapeutic targets for advanced disease.
