Stereotaxic localization for fine-needle aspiration breast biopsy. Initial experience with 300 patients.

Author information

Department of Radiology, Kaplan Cancer Center, Tisch Hospital, New York, NY.


The efficacy of stereotaxic aspiration biopsy was evaluated in 300 consecutive patients with nonpalpable mammographic lesions. Sixty-eight patients (23%) had suspicious or malignant aspirates; all cases were proved malignant by subsequent examination of operative specimens. Two hundred sixteen patients (72%) had benign aspirates. Of these, 65 were confirmed by operation and 151 had subsequent mammography at 6- and 12-month intervals with no demonstrable mammographic change. In 10 instances (3%), the aspirates were atypical, and in six (2%), nondiagnostic. Biopsy specimens were obtained in all 16 instances, and eight were malignant. The sensitivity of stereotaxic breast aspiration for the diagnosis of cancer was 96%, and the specificity was 100%. Our experience confirms the efficacy of stereotaxic aspiration for the initial evaluation of mammographically detected, nonpalpable lesions.
