AR and neoplasm: Indeed, six distinct molecular TNBC entities have been described: two basal-like-related subgroups (basal-like 1 [BL1] and 2 [BL2]), two mesenchymal-related subgroups (mesenchymal [M], mesenchymal stem-like [MSL]), one luminal androgen receptor (LAR) group, and one immunomodulatory (IM) subgroup, with MSL and IM subtypes that are driven by tumor-associated stromal cells and tumor-infiltrating lymphocytes (TILs), respectively, in the tumor microenvironment (TME) (Lehmann et al., 2011, 2016).
