We compared these signatures with those of EF and FOTS to determine the degree of overlap between cases with either of the two good prognosis signatures (EF and DTF fibroblast) and the overlap between cases with either of the bad prognosis signatures (FOTS and TGCT/CSF1 macrophage) in the four independent breast cancer datasets (NKI, GSE1456, GSE3494 and GSE4922). The gene discussed is CSF1; the disease is breast carcinoma.
