Background:
This study evaluates the safety, efficacy, and patient acceptance of a vacuum-assisted, hand-held biopsy device (Mammatome) in the percutaneous removal of breast masses using ultrasound guidance.
Methods:
A multicenter, nonrandomized study evaluated 216 women with low-risk palpable lesions. Lesions 1.5 to 3.0 cm in size were removed using an 8-gauge probe. Those lesions <1.5 cm were removed with the 11-gauge probe. Follow-up evaluation was performed at 10 days and 6 months after biopsy.
Results:
A total of 127 patients had biopsies using the 8-gauge probe, and 89 patients had biopsies using the 11-gauge probe. At 6-month follow-up, 98% of the lesions remained nonpalpable, 73% with no ultrasonographically visible evidence of the original lesion. Most complications were mild and anticipated. Most patients (98%) were satisfied with incision appearance, and 92% of patients would recommend the procedure to others.
Conclusions:
Percutaneous removal of palpable benign breast masses using the Mammotome system is feasible and safe, and yields high patient satisfaction. The results at 6 months after biopsy demonstrated the effectiveness of benign lesion removal, with correlative clinical data demonstrating lack of palpability and no need for additional procedures. Continuing evaluation of long-term efficacy is ongoing.
