How stereotactic core-needle biopsy affected breast fine-needle aspiration utilization: an 11-year institutional review.

Journal Article

To determine the effect of stereotactic core-needle biopsy (SCNB) on the utilization of breast fine-needle aspirate (FNA) biopsy, we retrospectively reviewed 1,568 cases of breast FNAs that were obtained from 1,188 patients between the years 1990 and 2000. There were 378 positive and atypical cases and 497 negative and unsatisfactory cases in the pre-SCNB group (between 1990 and 1996; 7 years); and 225 positive and atypical cases and 468 negative and unsatisfactory cases in the post-SCNB group (between 1997 and 2000; 4 years). The average number of cases per year in the pre- and post-SCNB groups was 125 and 173, respectively. While the average positive/atypical cases per year in both groups remained relatively constant, the average negative/unsatisfactory cases per year were significantly increased in the post-SCNB group (117 in the post-SCNB vs. 71 in the pre-SCNB). The increase in this group was due to a true increase in the negative diagnoses, since unsatisfactory rate decreased in the post-SCNB group (12.6% in the post-SCNB vs. 9.3% in the pre-SCNB). The sensitivity, specificity, positive predictive value, and negative predictive value were 90%, 79%, 92%, and 82% in the pre-SCNB group and 93%, 86%, 91%, and 90% for the post-SCNB group, respectively. In conclusion, the implementation of SCNB did not result in a decrease in the total number of breast FNAs; however, the distribution of cases changed. FNA is increasingly used to complete the triple test in clinically and radiographically negative cases.
