Determination of threshold values for determining the size of the fraction of steroid hormone receptor–positive tumor cells in paraffin‐embedded breast carcinomas

For 4 years we used a multiparameter DNA flow cytometric (MP‐FCM) technique to assess steroid hormone receptor expression in the diagnostic workup of routinely processed formalin‐fixed, paraffin‐embedded breast carcinomas as an alternative to immunohistochemistry (IHC) for the quantification of hormone receptor–positive cells. In all cases a positive fraction of hormone receptor–expressing epithelial cells was detected. This observation raised the question of what the cutoff value might be to distinguish receptor‐negative from receptor‐positive tumors.
