Negative findings on fine-needle aspiration biopsy of solid breast masses: patient management.
A series of 245 fine-needle aspirations of solid breast masses has been reviewed. Seven aspirations were reported as unsatisfactory, 178 revealed benign masses, 7 were indeterminate, and 53 revealed malignancy. Fifty-two of 53 masses diagnosed on aspiration as malignant were confirmed by surgical biopsy (98 percent sensitivity). Open biopsy was carried out on 50 of 178 masses reported as negative on needle biopsy and benign masses were revealed in 46 cases (92 percent specificity). The remaining 128 masses with negative findings were observed and follow-up of 101 patients obtained. Cancer did not develop in any of these patients. Careful physical examination and mammography can predict if a breast mass is malignant or benign in 85 to 90 percent of patients. If fine-needle aspiration biopsy is added and performed by physicians and cytopathologists experienced in the technique, additional information is obtained which allows greater diagnostic accuracy and may eliminate many breast biopsies.
