OBJECTIVE We examined the accuracy and cost-effectiveness of large-core needle breast biopsy in a selected group of patients with mammographically detected lesions. METHODS We selectively used large-core needle biopsy to sample breast lesions that were intermediate (neither clearly benign nor clearly malignant) and wire localization biopsy to sample breast lesions that were strongly suggestive of cancer. We compared 2 years' experience using this protocol with the preceding 2 years at the University of Utah Health Sciences Center during which we did only a few large-core needle biopsies on a nonselective basis. RESULTS Our biopsy rate increased from one biopsy per 36 mammographic screening examinations to one per 26 (p = .001) when the protocol was used. The cost of biopsy per cancer detected decreased from $11,555 to $8356. The specificity of large-core needle biopsy was 98%; the sensitivity based on limited follow-up was 100%. CONCLUSIONS Large-core needle biopsy is an accurate and cost-effective method for sampling breast lesions when used in a selective fashion.
