Abstract:
Objective To investigate the pathology of nonpalpable breast lesions(NPBL),and evaluate the diagnostic value of ultrasound-guided mammotome(MMT)biopsy.Methods Between January 2005 and December 2007,254 patients with NPBL(328 lesions)diagnosed by ultrasonography received ultrasound-guided MMT biopsy.Among the patients,176 were diagnosed as having no breast mass or calcification by mammography.Results Of the 328 lesions,269(82.0%)were fibroadenomas,34 were(10.4%)cysts,3(0.9%)were intraductal papillomas,19(5.8%)were adenosis,and 3(0.9%)were early breast cancers.Among the 254 cases,251(98.8%)were benign without positives findings during follow-up.These patients received simple MMT,and 239(95.2%)of them were satisfied with the cosmetic outcome.The other 3(1.2%)patients who had malignancies were treated with modified mastectomy;none of them had residual tumors.The underestimate rate for NPBL was 0 in our cases.Of the 251 benign patients who received only MMT biopsy,239(95.2%)have satisfactory cosmetic results.Conclusions As an effective,minimally invasive,and rapid diagnostic technique for NPBL,ultrasound-guided MMT biopsy is an optimal tool for "one-step" operation.By using the method,underestimate risk can be decreased.
