Vacuum-Assisted Breast Biopsy System: No Innovation Without Evaluation

Area of Science:

• Radiology
• Pathology
• Oncology

Background:

• Vacuum-assisted breast biopsy (VABB) is increasingly utilized for indeterminate breast lesions.
• It aims to improve diagnostic accuracy and reduce surgical interventions.

Purpose of the Study:

• To evaluate the outcomes of the VABB technique.
• To assess the impact of VABB on patient management strategies.

Main Methods:

• Retrospective analysis of 122 female patients undergoing image-guided VABB (8G and 11G needles).
• Data collected included patient demographics, lesion characteristics, and procedural outcomes.
• Biopsies were performed using stereotactic (SVAB) or ultrasound guidance (US-VAB).

Main Results:

• Histology was upgraded in 19.6% and downgraded in 18.8% of cases.
• In 61.4% of patients, the post-procedure histology remained unchanged.
• Mean lesion size was 14.8 mm; 50% SVAB and 50% US-VAB.

Conclusions:

• VABB is a safe and efficient procedure for diagnosing suspicious breast lesions.
• It yields adequate tissue for accurate histopathological diagnosis.
• VABB can help in upgrading or downgrading diagnoses, potentially avoiding unnecessary surgeries.
