Summary
The Advanced Breast Biopsy Instrumentation (ABBI) procedure for nonpalpable breast lesions had a high rate of complications and technical failures. Alternative methods like stereotactic or sonographically guided needle biopsy are recommended for tissue diagnosis.
Area of Science:
- Radiology
- Surgical Oncology
- Pathology
Background:
- The Advanced Breast Biopsy Instrumentation (ABBI) device offers percutaneous excision for nonpalpable breast lesions.
- Evaluating new minimally invasive techniques is crucial for improving breast cancer diagnosis and treatment.
Purpose of the Study:
- To assess the initial clinical experience with the ABBI device.
- To determine the technical success rate, complication profile, and margin status for malignancies excised by ABBI.
Main Methods:
- Eighty-nine patients underwent the ABBI procedure between May 1997 and March 1998.
- Preprocedure imaging included mammography and sonography; specimen radiography and pathologic analysis were performed for all excised lesions.
- Key parameters analyzed were technical success, complications, lesion characteristics, and margin status for malignant tumors.
Main Results:
- Eighteen ABBI procedures (20.2%) were unsuccessful or converted to core biopsy.
- Nineteen complications occurred in 15 patients, with 10 requiring further treatment.
- Of 11 malignant tumors, only 4 achieved negative margins; 7 had positive margins.
Conclusions:
- The ABBI procedure demonstrated a high incidence of complications and technical failures.
- ABBI did not reliably achieve cancer-free margins for malignant breast lesions.
- Stereotactic or sonographically guided needle biopsy is a preferred alternative for tissue diagnosis of nonpalpable breast lesions.
