Summary
Successful removal of nonpalpable breast lesions during mammography-guided needle-localized breast biopsy depends on wire placement. Keeping the localization wire within 5 mm of the lesion significantly improves successful excision rates.
Area of Science:
- Radiology
- Breast Imaging
- Surgical Oncology
Background:
- Nonpalpable breast lesions require precise localization for successful biopsy.
- Mammography-guided needle-localized breast biopsy is a common technique for excising these lesions.
Purpose of the Study:
- To identify predictive factors for successful removal of nonpalpable breast lesions using mammography-guided needle-localized breast biopsy.
Main Methods:
- Retrospective review of 272 patients undergoing needle-localized breast biopsy.
- Analysis of factors including wire-lesion distance, breast density, breast size, and specimen/lesion volume.
- Radiographic evaluation by two expert breast imaging radiologists.
Main Results:
- The procedure was successful in 93.3% of lesions.
- Localization wire placement within 5 mm of the lesion was a significant predictor of success (P = .007).
- Factors associated with biopsy failure included increased wire distance, smaller breast size, and smaller specimen volume.
Conclusions:
- Optimal localization wire placement within 5 mm of mammographically visible lesions is crucial.
- This technique enhances the probability of successful lesion excision.
