Summary
Vacuum-assisted biopsy (VB) is a reliable method for evaluating breast lesions, offering high accuracy comparable to open surgery with minimal side effects. Patient positioning during the procedure does not impact its effectiveness or complication rates.
Area of Science:
- Radiology
- Oncology
- Pathology
Background:
- Vacuum-assisted biopsy (VB) is an increasingly utilized technique for breast lesion diagnosis.
- Accurate histological evaluation is crucial for effective breast cancer management.
- Understanding the impact of patient positioning on VB accuracy and safety is important.
Purpose of the Study:
- To determine the diagnostic accuracy of vacuum-assisted biopsy (VB) for breast lesions.
- To evaluate potential side effects of VB based on patient positioning during the procedure.
Main Methods:
- VB was performed using an 11-G needle in either prone or upright positions.
- Indications for VB included suspicious microcalcifications (84.1%) and dense lesions (15.9%).
- Benign VB results were followed up with mammography; discordant malignant results were verified by open surgery.
Main Results:
- VB yielded benign results in 64.4% of cases, with no subsequent carcinoma development during follow-up.
- Malignancy was detected in 27% of VB cases, with 85.6% confirmed upon reexcision.
- No major side effects were observed regardless of patient position (prone or upright).
Conclusions:
- Vacuum-assisted biopsy (VB) is a reliable and accurate method for histological evaluation of breast lesions.
- VB accuracy and complication rates are independent of patient positioning or stereotactic device type.
- VB offers comparable accuracy to open surgery with fewer side effects, despite potentially higher initial costs.
