Stereotactic core needle biopsy for diagnosis of mammographic minimal lesions / 浙江大学学报·医学版

ABSTRACT

<p><b>OBJECTIVE</b>To assess the value of X-ray stereotactic core needle biopsy (SCNB) in diagnosis of mammographic minimal lesions.</p><p><b>METHODS</b>Thirty-one cases with suspicious malignant lesions detected by mammography underwent breast biopsy using computer-assisted stereotactic system with spring-loaded biopsy guns and 16G core needles. All specimens underwent histopathologic examination. Surgical operations were performed in 24 cases after SCNB, and pathological findings of SCNB specimens were compared with those of surgical biopsy.</p><p><b>RESULT</b>Among 24 cases with surgical excision, 8 cases (33.3%) were confirmed as breast carcinoma, and the other 16 cases (66.7%) was benign breast lesions. The consistency rate of diagnosis with two methods was 87.5%.</p><p><b>CONCLUSION</b>As a safe and effective diagnostic method, SCNB is preferred approach to differentiate between malignant and benign diseases of minimal breast lesions before surgery.</p>
