Ultrasound-guided minimally invasive Mammotome biopsy system for breast benign tumor and early breast cancer

Objective To investigate the value of ultrasound-guided minimally invasive Mammotome biopsy system in the treatment of breast tumor.Methods Totally 196 cases in 285 breast lesions were treated by ultrasound-guided minimally invasive Mammotome biopsy system.Results The 285 lesions in the 196 patients were excised completely by using the Mammotome system.The excision was performed for a mean of 13 times in each case(ranged from 5 to 28 times)with mean operation time of 30 minutes(15 to 60 minutes).Skin ecchymosis was found in 2 patients after operation.The length of the incisional scar was not obvious with a range from 2.5 to 5.0 mm.Of all,175 lesions were diagnosed as fibroadenoma,12 lesions as breast adenosis,6 lesions as intraductal papilloma,3 lesions as breast cancer.The 196 cases were followed up by ultrasound and no local recurrence was found.Conclusions Ultrasound-guided minimally invasive Mammotome biopsy system is feasible for total resection of breast tumor with appropriate sizes.The technique leads to rare complications and good cosmetic results,which may provide an option for diagnosis and treatment of suspicious breast lesions.
