Stereotactic Needle Biopsy of Non-palpable Mammary Lesion: Strict Selecting Proper Candidate

Objective To improve the success rate of stereotactic needle core biopsy (SCNB) and stereotactic mammographic needle-localized biopsy (SNLB).Materials and Methods One hundred and thirteen cases with breast lesion, which were non-palpable clinically but could be detected on mammograph, underwent SCNB or SNLB. Factors influencing the success rate of SCNB and SNLB were analyzed.Results Of 72 cases receiving SCNB, the procedure was successfully completed in 59, of which the lesion was benign in 43 and malignant in 16. Of 41 cases receiving SNLB, the procedure was well completed in 37, of which the lesion was benign in 26 and malignant in 11. Factors influencing success rate included the accuracy of localizing mark, lesion's site within the breast and patient's physical condition.Conclusion SCNB and SNLB are mainly used in diagnosing non-palpable breast lesion. Strict selecting the proper candidate is the guarantee against technical failure.
