The Pearson test did not show the existence of any significant correlations between the tumour cell TSP staining, stromal TSP staining, TSP-positive cell zone composed of macrophages, MVD, and any of the conventional tumour features, including tumour size, tumour grade, vascular invasion, status of axillary lymph nodes, extranodal spread, ER immunostatus, and PR immunostatus. This evidence concerns the gene PGR and neoplasm.
