OBJECTIVE: To correlate histologic and cytologic specimens of breast cancer by the expression of prognostic factors, such as estrogen receptor (ER), progesterone receptor (PR) and c-erbB-2, with immunochemical staining. STUDY DESIGN: Cytologic and histologic specimens from 83 patients were analyzed for expression of ER and PR, and 30 cases were analyzed for overexpression of c-erbB-2 using a standard immunochemical method. The material used for immunocytochemical staining was taken from the needle and syringe after each aspiration and smear preparation. The material was washed into a small container with preservative solution. Immunohistochemical staining was performed on paraffin-embedded specimens. RESULTS: A significant association was found between the histologic specimens and cytologic specimens by means of the expression of immunochemical markers. The best correlation between cytologic and histologic specimens was found when using c-erbB-2. CONCLUSION: A reliable and rapid evaluation of markers for breast cancer can be achieved by immunocytochemical staining on cytologic material. A good association was found between histologic and cytologic specimens using immunostaining.
