Automated large-core breast biopsy is a reliable alternative to surgical biopsy. This study confirms its reproducibility across multiple institutions for accurate breast cancer diagnosis.

Area of Science:

  • Radiology and Oncologic Imaging
  • Minimally Invasive Procedures

Background:

  • Accurate breast lesion diagnosis is crucial for effective cancer treatment.
  • Surgical biopsy has traditionally been the standard, but carries higher risks and costs.

Purpose of the Study:

  • To evaluate the reliability and reproducibility of automated large-core breast biopsy.
  • To compare its diagnostic accuracy against surgical biopsy outcomes.

Main Methods:

  • A multi-institutional study involving 20 centers.
  • Standardized collection of core breast biopsy data using 14-gauge needles and "long-throw" devices.
  • Biopsies guided by stereotactic or ultrasound imaging.

Main Results:

  • Data from 6,152 lesions were analyzed.

  • In 1,363 surgically excised lesions, automated core biopsy showed cancer in 910, mammary intraepithelial neoplasia in 173, and benign disease in 280.
  • A low false-negative rate of 15 out of 280 benign diagnoses was observed.

    • Conclusions:

    • Percutaneous large-core breast biopsy demonstrates high reliability and reproducibility.
    • It serves as a viable and accurate alternative to surgical biopsy for breast lesion evaluation.
