Efficacy after Excisional Biopsy of Breast Mass with Ultrasound-guided Vacuum Assisted Biopsy Device (Mammotome)

PURPOSE: The aim of this study is to evaluate the rate of residual lesion after US-guided mammotome biopsy for breast mass and evaluate the efficacy of mammotome biopsy device. MATERIALS AND METHODS: A total of 902 US-guided excisional mammotome biopsies were performed in 902 lesions of 474 women (mean age 42.1 years, age range 17-75 years), from January 2003 to December 2006 in Chosun University Hospital. After mammotome biopsy, ultrasonographic follow-up were performed on 6 or 12 months later to assess residual tumor. RESULTS: Remnant tumor was found in 39 lesions (4.3%, mean age 41.8years, range 19-55 years) of total 902 lesions 니nderwent mammotome biopsy. Pathologic diagnoses were fibrocystic change in 16 lesions, fibroadenoma in 19 lesions and other benign breast lesions in 4. Mean size was 1.09 cm before mammotome biopsy. CONCLUSION: Ultrasound-guided vacuum-assisted biopsy device was an effective method for small breast mass. Although there was a possibility of remnant tumor, the remnant rate was low. Also, there was advantage of cosmetic effect for small incision scar. The results suggested that mammotome biopsy is a good alternative method for the diagnosis of small breast mass.
