Expression of somatic-stem transition genes and macrophage-associated genes in breast tumor

In a study of breast cancer of 68 patients before and after neoadjuvant chemotherapy, overexpression in the residual tumor of 14/16 genes of the somato-stem transition was shown in patients with metastases that subsequently developed. This confirms our hypothesis about the important role of activation of the ability to somato-stem transition for tumor metastasis, which occurs under the influence of neoadjuvant chemotherapy. A new prognostic factor has been established, which makes it possible to predict the occurrence of hematogenous metastases with a sensitivity of 69%, a specificity of 94%, and a diagnostic accuracy of 82%
