Abstract
Eighty-one consecutive patients with breast masses clinically suspicious for malignancy were evaluated prospectively. There were 31 benign lesions and 50 malignancies. Clinical diagnosis was correct in 85% (2.5% false negative, 12.5% false positive). Mammography was diagnostic in 52.8% (31.5% false negative, 15.7% false positive). Needle biopsy was accurate in 78.9% (21.1% false negative, 0% false positive). Aspiration cytology was diagnostic in 96.2% (3.8% false negative, 0% false positive). Statistical comparison of all four tests revealed that aspiration cytology was slightly more accurate than physical examination for all lesions (p = 0.07), but significantly more accurate for benign lesions (p = 0.005). Overall, aspiration cytology was significantly more accurate than mammography (p = 0.000001) and needle biopsy (p = 0.008). Only one minor complication, a superficial infection, occurred with aspiration cytology and needle biopsy. Thin-needle aspiration cytology is a benign procedure that appears to be superior to physical examination, mammography, and needle biopsy in establishing the diagnosis of clinically suspicious breast masses.Keywords
