Our previous results showed that tumor infiltrating monocytes/macrophages (CD14<sup>+</sup>/CD16<sup>+</sup>) isolated from inflammatory breast cancer (IBC) patients' secrete high levels of IL-10.
Moreover, the expression of interleukin-10 messenger RNA was significantly higher (p < 0.001) by 5.28-fold and 8.95-fold than non-inflammatory breast cancer and healthy control, respectively, where GCC haplotype significantly increased interleukin-10 gene expression (r = 0.9, p < 0.001).
