False-negative diagnoses at stereotactic vacuum-assisted needle breast biopsy: long-term follow-up of 1,280 lesions and review of the literature.

Objective: The purpose of this study was to determine retrospectively the frequency and causes of false-negative diagnoses of lesions evaluated with percutaneous stereotactic biopsy performed with vacuum-assisted probes with the patient prone on a biopsy table.

Materials And Methods: The records of 1,152 women (median age, 55 years; range, 31-94 years) with 1,280 lesions consecutively biopsied with 14-gauge (n = 159) or 11-gauge (n = 1,121) vacuum probes were reviewed retrospectively. The histologic diagnoses were malignant (n = 489), high-risk (n = 117), and benign (n = 674) lesions.

Stereotactic histologic biopsy with patients prone: technical feasibility in 98% of mammographically detected lesions.

Objective: The purpose of this retrospective study was to determine which mammographically detected lesions in need of imaging-guided biopsy could undergo prone, stereotactic biopsy.

Materials And Methods: From July 1991 through June 2001, 1687 consecutive patients (age range, 29-94 years; median age, 58 years) with 1894 lesions were referred by clinicians in a multispecialty clinic. The patients underwent stereotactic, prone, histologic biopsy of 1851 lesions (98%) and needle-localized breast biopsy of 43 lesions (2%).

Stereotactic, automated, large-core needle biopsy of nonpalpable breast lesions: false-negative and histologic underestimation rates after long-term follow-up.

Purpose: To determine the rate and causes of false-negative findings and histologic underestimates at stereotactic biopsy of nonpalpable breast lesions.

Materials And Methods: Stereotactic, 14-gauge, automated, large-core needle biopsy (LCNB) was performed in 483 consecutive nonpalpable breast lesions. Excision was advised for the 143 carcinomas, 25 atypical ductal hyperplasia (ADH) lesions, and five radial scars.

Percutaneous removal of benign mammographic lesions: comparison of automated large-core and directional vacuum-assisted stereotactic biopsy techniques.

Objective: The purpose of our study was to evaluate how often histologically benign lesions were completely removed as shown by the initial mammogram after biopsy. We compared three percutaneous biopsy techniques.

Materials And Methods: Retrospective review was performed on 1206 consecutive impalpable breast lesions having percutaneous stereotactic biopsies done on a prone biopsy table using 14-gauge automated large-core needles (n = 721); 14-gauge directional vacuum-assisted probes (n = 192); and 11-gauge directional vacuum-assisted probes (n = 293).

Needle-localized breast biopsy: why do we fail?

Purpose: To determine what factors are associated with unsuccessful needle-localized breast biopsy (NLBB).

Materials And Methods: Findings in 280 consecutive nonpalpable breast lesions in 262 women (age range, 27-87 years; mean age, 55 years) who underwent nonstereotactic, mammographically guided, standardized NLBB were retrospectively analyzed according to mammographic lesion type, lesion size, number of lesions per breast, needle type, proximity of needle to lesion, radiologist, specimen size, surgeon, and histologic findings.

Results: Biopsy failed in seven (2.
