En bloc excision of nonpalpable breast lesions using the advanced breast biopsy instrumentation system: an alternative to needle guided surgery?
This study was prospectively conducted to evaluate the clinical potential of the advanced breast biopsy instrumentation (ABBI) system as an alternative to needle localization and open surgery in the management of nonpalpable breast lesions (NPBL). One hundred and eighty-six consecutive patients were referred for management of NPBL. Thirty-six underwent an ABBI procedure, offered as a first step before possible surgery for lesions which would in any case have required complete excision. The 18 patients with a malignant ABBI biopsy underwent re-excision of the biopsy site and axillary dissection was carried out in cases of infiltrating carcinoma. The other 150 patients underwent image-guided needle biopsy. Following these procedures, 60/150 (40%) patients underwent needle-guided surgery. Finally, 96/186 (51%) patients required complete excision. A total of 43 benign lesions and 53 carcinomas were confirmed. Thirty-six out of 96 (38%) excisions were obtained with the ABBI system; 17/43 (40%) benign lesions and 11/53 (21%) carcinomas were completely removed with the ABBI system. Out of 9 malignant specimens with a pathological size less than 10 mm, 5/9 (55%) had tumor-free margins and in 8/9 (89%) no residual disease was found at re-excision. The preliminary results of this study suggest that, in selected cases, en bloc excision using the ABBI procedure could be an alternative to conventional surgery.
