Summary
Percutaneous biopsy (BP) is effective for diagnosing nonpalpable breast lesions. Vacuum-assisted core biopsy (VACB) is recommended due to its ease of use and adaptability.
Area of Science:
- Radiology
- Oncology
- Pathology
Background:
- Percutaneous biopsy (BP) offers a viable alternative to open surgical biopsy for breast lesion diagnosis.
- Evaluating vacuum-assisted core biopsy (VACB) and advanced breast biopsy instrumentation (ABBI) is crucial for diagnostic accuracy.
Purpose of the Study:
- To assess the diagnostic value and outcomes of VACB and ABBI for nonpalpable breast lesions.
- To compare the efficacy of different percutaneous biopsy techniques.
Main Methods:
- A total of 360 percutaneous biopsies were performed between June 1999 and December 2001.
- Procedures utilized a digital stereotactic table with a vacuum suction aspiration system for VACB and a cutting cannula for ABBI.
- Indications included microcalcifications (73.3%), nodular opacities (17.8%), and parenchymal distortions (8.8%).
Main Results:
- All biopsies were technically successful.
- Malignant lesions were identified in 19.7% of cases, and benign lesions in 71.6%.
- Atypical ductal hyperplasia was found in 8.6% of lesions removed with VACB.
Conclusions:
- Percutaneous biopsy is a valid diagnostic method for nonpalpable breast lesions.
- VACB is the preferred method due to its simplicity and high adaptability in clinical practice.
