Fine-needle aspiration (FNA) cytology is being increasingly employed in conjunction with physical examination and mammography in the pre-surgical diagnosis of breast nodules. In the present study, we have submitted to multicenter validation an immunocytochemical test which employs monoclonal antibodies (MAbs) to breast-tumor-associated antigens (BTAA) for the diagnosis of breast cancer. The results of this analysis, which has evaluated 846 FNAs, show that the immunological test has a sensitivity of 88.62%, a specificity of 97.9% and an accuracy of 92.4%. The predictive value of a positive and a negative finding were 98.4% and 85.57% respectively. Comparison between the cytological and immunocytochemical diagnosis displayed a higher sensitivity, accuracy and predictive value of a negative result with the latter method (p less than 0.01). Our findings clearly indicate that immunocytochemical methods can complement and improve the diagnostic accuracy of FNA cytology of breast nodules.

Abstract

Fine-needle aspiration (FNA) cytology is being increasingly employed in conjunction with physical examination and mammography in the pre-surgical diagnosis of breast nodules. In the present study, we have submitted to multicenter validation an immunocytochemical test which employs monoclonal antibodies (MAbs) to breast-tumor-associated antigens (BTAA) for the diagnosis of breast cancer. The results of this analysis, which has evaluated 846 FNAs, show that the immunological test has a sensitivity of 88.62%, a specificity of 97.9% and an accuracy of 92.4%. The predictive value of a positive and a negative finding were 98.4% and 85.57% respectively. Comparison between the cytological and immunocytochemical diagnosis displayed a higher sensitivity, accuracy and predictive value of a negative result with the latter method (p less than 0.01). Our findings clearly indicate that immunocytochemical methods can complement and improve the diagnostic accuracy of FNA cytology of breast nodules.
