FOXP3 and neoplasm: Similarly, FoxP3+ T cells have been shown to predict poor survival when located within the tumour nests but not in stroma that is at least one cell away from tumour cells, although this was not broken down on ER status [27], and the correlation has also been reported specifically in ER-positive but not in ER-negative cases, although this study failed to differentiate between tumour compartments [28].
