Hormone receptor and human epidermal growth factor receptor 2 status evaluation on ThinPrep specimens from breast carcinoma

Abstract

Alcohol-based fixation seems not to affect the immunocytochemical evaluation of HR and HER2. Considering the high levels of agreement between the evaluation of HR and HER2, on both cytology specimens and on the corresponding FFPE tissue samples, the authors concluded that the TP technique can be routinely used for the biological characterization of IBC.
