The value of ultrasound guilded needle-wire localization of nonpalpable breast neoplasm before surgical excise

Objective To evaluate the efficacy of surgical excise of occult breast nerplasm localized by needle wire under ultrasound guildance.Methods Fifty-eight nonpalpable brease lesions and 3 enlarged axillary lymph node were detected by ultrasonography,and all 61 lesions were executed hook wire localization puncture guilded by untrasound preoperatively.Results All localized lesions were removed accurately.Histologically,16 of all 61 lesions were maligant(26.2%),including 3 in situ carcinomas,8 early stage invasive carcinomas,4 invasive carcinomas,and 1 lymph node metastatic carcinoma.The remaining 45 lesions were benign(73.8%).The sensitivity and specificity of ultrasonography for carcinoma was 93.8% and 91.1% respectively.Conclusion Ultrasound-guided wire localization of breast occult lesions is not only useful in assisting surgical biopsy,but also helpful in early diagnosis and treatment of breast carcinoma.
