[Stereotactic fine-needle aspiration biopsy (FNAB) of nonpalpable breast lesions: cyto-histological correlations].
There are not complete consensus if mammographically guided FNABs of nonpalpable breast lesions can replace open biopsy. To elucidate this problem, we have reviewed the efficacy of stereotactic FNAB in a series of 502 cases of nonpalpable lesions observed in a period from 1990 to 1994, with a immediate cytologic control of adequacy of material. In 144 patients of the lesion is achieved with 4% sterile coal localisation and an open biopsy of the area performed. In each case cytologic findings, with a brief description of probable histotype of the lesion, are correlate with surgical pathologic diagnosis, with a comparison between two time period (1990-92; 1993-94). In our study particularly ductal and lobular hyperplasia (with or without atypia) restrict the efficiency of the FNAB. In fact the specificity varies from 83.3% to 90.3%, the sensitivity from 78.7% to 77.8%, positive predictive value from 86.0% to 90.3%, negative predictive value from 75.6% to 70% and diagnostic accuracy from 80.0 to 82.4%, considering ductal and lobular hyperplasias as true negatives or true suspects. Cytologically we have 2 false positive in the first period of time, 3 false suspects in the second period of time and 7 false negatives. However benign/malign biopsy ratio is well (0.97). Moreover histopathologic informations of cytological diagnosis is variable according the histotype of the lesion. In conclusion our study confirm that FNAB is an reliable method that avoid unnecessary biopsy but is insufficiently sensitive to replace open biopsy of nonpalpable breast lesions, also with an immediate cytological control of adequacy of aspirate.
