Needle-localized breast biopsy: why do we fail?

Summary

Unsuccessful needle-localized breast biopsy (NLBB) is linked to multiple lesions, small tumors, and microcalcifications. Accurate needle placement and sufficient tissue removal improve success rates for these challenging breast biopsies.

Area of Science:

  • Radiology
  • Surgical Oncology
  • Breast Imaging

Background:

  • Needle-localized breast biopsy (NLBB) is a standard procedure for nonpalpable breast lesions.
  • Identifying factors associated with biopsy failure is crucial for optimizing patient outcomes.

Purpose of the Study:

  • To identify factors contributing to unsuccessful needle-localized breast biopsy (NLBB).

Main Methods:

  • Retrospective analysis of 280 nonpalpable breast lesions in 262 women undergoing mammographically guided NLBB.
  • Evaluation of lesion characteristics, procedural details, and radiologist/surgeon factors.

Main Results:

  • Biopsy failure occurred in 2.5% of lesions.
  • Factors associated with failure included lesion type (microcalcifications), small lesion size, multiple lesions per breast, and inadequate specimen volume.
  • Re-biopsy with additional tissue removal converted initial failures to success in 67% of cases, particularly for microcalcifications.

Conclusions:

  • Unsuccessful NLBB is more probable with multiple lesions, small lesions, small specimens, and microcalcifications.
  • Ensuring accurate needle placement and obtaining adequate tissue volume are key to successful biopsy.
  • Additional tissue removal is beneficial for missed microcalcifications.
