OBJECTIVE: The purpose of this study was to compare the usefulness of, and cost of diagnosing with, different breast biopsy methods for @entity1 with @entity730 highly suggestive of @entity5 . MATERIALS AND METHODS: One hundred thirty-nine @entity1 with @entity730 highly suggestive of @entity5 underwent diagnostic biopsy. Of these, 89 @entity1 had stereotactic biopsy with a 14-gauge automated needle (n = 25), 14-gauge vacuum-assisted probe (n = 17), or 11-gauge vacuum-assisted probe (n = 47); and 50 @entity1 had diagnostic surgical biopsy. Medical records were reviewed. Cost savings for stereotactic biopsy were calculated using Medicare data. RESULTS: The median number of operations was one for @entity1 who had stereotactic biopsy versus two for @entity1 who had diagnostic surgical biopsy. The likelihood of undergoing a single operation was significantly greater for @entity1 who had stereotactic rather than surgical biopsy, among all @entity1 (61/89 [68.5%] vs. 19/50 [38.0%], p < 0.001) and among @entity1 treated for @entity0 (55/77 [71.4%] vs. 6/37 [16.2%], p = 0.0000001). Stereotactic 11-gauge vacuum-assisted biopsy, as compared with 14-gauge automated core or 14-gauge vacuum-assisted biopsy, was significantly more likely to spare a surgical procedure (36/47 [76.6%] vs. 16/42 [38.1%], p = 0.0005). Stereotactic 11-gauge vacuum-assisted biopsy resulted in the greatest cost reduction, yielding savings of  315 per case compared with diagnostic surgical biopsy; for @entity1 with solitary lesions, stereotactic 11-gauge biopsy decreased the cost of diagnosis by 22.2% ( 334/ 1502). CONCLUSION: For @entity1 with @entity730 highly suggestive of @entity5 , the use of stereotactic rather than surgical biopsy decreases the number of operations. Stereotactic 11-gauge vacuum-assisted biopsy, as compared with 14-gauge automated core or 14-gauge vacuum-assisted biopsy, is significantly more likely to spare a surgical procedure and has the highest cost savings.
