Summary
The advanced breast biopsy instrumentation (ABBI) system faced challenges with patient suitability and technical issues. Despite appearing clear radiologically, most malignant cases treated with ABBI had residual cancer at incision margins.
Area of Science:
- Oncology
- Surgical Instrumentation
- Diagnostic Imaging
Background:
- The advanced breast biopsy instrumentation (ABBI) system was initially promising for breast lesion diagnosis.
- Concerns emerged regarding patient selection, device functionality, and the adequacy of lesion removal for malignant cases.
Purpose of the Study:
- To evaluate the efficacy of the ABBI system in complete lesion removal.
- To assess the status of incision margins in malignant breast lesions after ABBI procedures.
Main Methods:
- Retrospective review of 183 patients undergoing ABBI in the first year of use.
- Analysis of patient rejections, technical difficulties, and pathological examination of incision margins for malignancies.
Main Results:
- 26% of patients were unsuitable for ABBI.
- 23% of biopsies experienced technical difficulties.
- 14 malignancies were diagnosed; radiologically clear margins were observed in all.
- Pathological examination revealed residual malignancy in 93% of these cases.
Conclusions:
- The ABBI system demonstrated significant rates of patient unsuitability and technical complications.
- Radiological assessment of margins after ABBI is insufficient for determining complete removal of malignancy.
- Pathological evaluation is crucial, as most ABBI-treated malignancies had residual disease at incision margins.
