The evaluation of estrogen receptor ER progesterone receptor PR and human epidermal growth factor receptor 2 HER2 expression by immunohistochemistry IHC is performed routinely on formalin-fixed paraffin-embedded needle-core NC or excision tissue block TB preparations accordlngto the American Society of Clinical Oncology College of American Pathologist guidelines. In this retrospective study the authors compared expression levels of ER. PR. and HER2 in ethanol-fixed BC FNA cell block CB samples with expression levels in formalin-fixed NC and TB samples. METHODS Forty-one breast carcinoma CB samples with concurrent or subsequent NC and TB samples were identified. Patients who had received neoadjuvant or adjuvant chemotherapy were excluded. CB samples initially were fixed in 50 ethanol 4-12 hours and this was followed by formalin fixation minimum 6 hours . NC samples were placed promptly in formalin for a minimum of 6 hours. Within 4 to 8 hours TB samples were fixed in .
