Frequency of Discordant Lesions and False-negative Cancers at Stereotactic Vacuum-assisted Biopsy

A relatively low discordance rate (1.2%) was observed. However, a high percentage (30%; range in literature 11.7%-53.8%) of our discordant lesions were false negatives. This study emphasizes the need for careful radiological-pathologic review after SVAB and for repeat biopsy or surgical excision in the setting of discordance.
