Breast cancer is a heterogeneous disease, and the influence of stromal gene and protein
expression patterns on the biological and clinical heterogeneity of the disease is poorly
understood. We previously demonstrated that evaluation of the gene expression patterns of
two soft-tissue tumors (desmoid-type fibromatosis (DTF) and solitary fibrous tumor) could be
used to identify distinct stromal reaction patterns in breast carcinoma. In the current study,
we examined four additional data sets obtained from four different institutions and containing …
