In triple-negative breast cancers, β-catenin alteration was associated with high levels of infiltration of TAMs in all compartments (intratumoral, p = 0.023; stromal, p = 0.001; total, p = 0.023), and SMA expression was associated with a high level of infiltration of stromal TAMs (p = 0.042) (S6 Table). This evidence concerns the gene SMN1 and triple-negative breast carcinoma.
