Accuracy and outcomes of stereotactic vacuum‐assisted breast biopsy for diagnosis and management of nonpalpable breast lesions

Stereotactic vacuum‐assisted biopsy (SVAB) is an alternative method of breast biopsy for nonpalpable lesions detected by mammography. Considering the diagnostic effectiveness, a direct comparison of SVAB and open surgical biopsy (OSB) is lacking. We performed a retrospective review of 276 (33.8%) SV...

Description
Summary:Stereotactic vacuum‐assisted biopsy (SVAB) is an alternative method of breast biopsy for nonpalpable lesions detected by mammography. Considering the diagnostic effectiveness, a direct comparison of SVAB and open surgical biopsy (OSB) is lacking. We performed a retrospective review of 276 (33.8%) SVAB and 541 (66.2%) OSB to compare the diagnostic accuracy and the total number of procedures the patients underwent. The negative predictive values of OSB and SVAB were 99.77% and 99.61%, and their false‐negative rates were 0.96% and 4.76%, respectively. SVAB, as the first‐line biopsy method, obviated 92.3% of operations. All malignancies diagnosed using SVAB could be treated with single therapeutic surgery. By contrast, 48% of malignancies of OSB group received two operations. Breast Imaging Reporting and Data System (BI‐RADS) category used at the study correlated well with the percentage of malignancy and can thus be used to predict biopsy results. Our study concluded that SVAB is reliable for diagnosing nonpalpable breast lesions and is the better biopsy method for categories 3 and 4A lesions, which reduces the benign surgery rate. For lesions with a higher likelihood of malignancy, BI‐RADS 4B, 4C and 5, SVAB has an advantage over OSB, which lowers the total number of operations for malignancy treatment.
