Abstract
The authors report on 228 cases of suspected breast cancer local recurrences studied by fine needle aspiration cytology (FNAC). The nature (malignant = 133, benign = 95) of suspected lesions was assessed on histology (no. = 46) or according to unequivocal follow-up (no. = 182). Inadequacy rate was 0.20, 0.09 or 0.35 in total, cancer or benign cases, respectively, and was particularly high (0.50) for benign chest wall lesions. Accuracy was determined on adequate smears; dubious reports were assumed as positive. Sensitivity and specificity were 0.96 and 0.97, respectively. The routine use of FNAC is recommended since it helps in the differential diagnosis of suspicious cases and may bypass surgical biopsy of positive cases not eligible for surgical treatment.
