Area of Science:

  • Radiology
  • Breast Imaging
  • Surgical Oncology

Background:

  • Accurate diagnosis of suspicious breast lesions is crucial for effective treatment.
  • Minimally invasive biopsy techniques are preferred to reduce patient morbidity.
  • Ultrasound (US) guidance offers real-time visualization for percutaneous procedures.

Purpose of the Study:

  • To evaluate the efficacy of ultrasound (US)-guided automated large-core percutaneous needle breast biopsy.
  • To compare the diagnostic accuracy of this technique with surgical excisional biopsy.
  • To assess the safety and procedural time of US-guided automated large-core needle biopsy.

Main Methods:

  • 181 ultrasonographically suspicious breast lesions underwent biopsy using a 14-gauge automated large-core needle system.

  • A "freehand" technique with continuous US guidance was employed.
  • Needle core diagnoses were compared with surgical diagnoses for 49 excised lesions; the remaining 132 were followed clinically.

    • Main Results:

    • 100% agreement was observed between needle-core and surgical diagnoses in the 49 excised lesions.
    • 34 cancers were diagnosed, including various types of invasive and in situ carcinomas.
    • No cancers were detected in the 132 lesions followed for 12-36 months; the procedure averaged 20 minutes with no complications.

    Conclusions:

    • Ultrasound-guided automated large-core percutaneous needle breast biopsy demonstrates high diagnostic accuracy, comparable to excisional biopsy.
    • This technique provides a safe, efficient, and effective alternative to surgical biopsy for suspicious breast lesions.
    • It offers a valuable tool in breast cancer diagnosis, potentially reducing the need for invasive surgical procedures.
