Diagnostic cytology in breast cancer screening.
In the period 1977-1978, 245 solid or cystic breast tumors and 134 nipple secretions were evaluated cytologically at the Trieste Cancer Institute. The results are discussed in the light of literature reports, and the high incidence of unsatisfactory smears observed in the group of malignant lesions (14,7%) is attributed to incorrect technique in specimen collection. The incidence of false positives and false negatives was 0,2% and 2,9%, respectively. The data reported are insufficient for significant statistical conclusion, but nevertheless confirm further the diagnostic importance of breast cytology whose routine practice in patient study protocols for breast cancer is highly recommended.
