[Digital roentgen-guided large-needle biopsy as an alternative to surgical biopsy in patients with nonpalpable mammographic abnormalities].
OBJECTIVE
To compare histopathological findings from stereotaxic needle core biopsies and from excision biopsies performed on patients with impalpable breast lesions suggestive of carcinoma.


METHODS
Prospective and descriptive, with a description of the stereotaxic needle core biopsy procedure.


METHODS
Academic Hospital Utrecht, the Netherlands.


METHODS
In 36 patients core biopsies were done with 14-gauge biopsy needles, followed by a localisation procedure with surgical biopsy. The pathological features of the core and excision specimens were compared.


RESULTS
Results of 35 (97%) core biopsies corresponded to those of excision biopsies. Stereotaxic core biopsy was not possible due to technical problems in 2 cases.


CONCLUSIONS
Stereotaxic core biopsy appears to be an acceptable alternative to excision biopsy.
