TLDR
Findings may suggest a higher diagnostic accuracy of biopsies performed with 12-gauge needles due to the larger samples obtained and/or due to a better radiological selection of those lesions, which were detected by digital mammography and biopsied under digital stereotactic guidance.
Abstract
Com o objetivo de avaliar o desempenho das agulhas de calibres 14 e 12 na obtencao de "core biopsies" da mama sob controle estereotaxico, os autores compararam biopsias de lesoes mamarias impalpaveis obtidas com agulhas desses calibres quanto ao tamanho dos fragmentos e frequencia dos tipos de lesoes diagnosticadas. De um total de 1.009 biopsias, os autores analisaram 900 obtidas por agulhas 14 e 109 obtidas por agulhas 12, para analise da frequencia das lesoes. Os tamanhos dos fragmentos foram analisados nos 700 primeiros casos para os especimes obtidos por agulhas 14. A utilizacao de agulhas 12 resultou em maior tamanho dos fragmentos (p < 0,001), ausencia de material insatisfatorio, reducao na proporcao das lesoes benignas nao-neoplasicas (p = 0,03) e aumento na frequencia de carcinomas (p < 0,001), tanto in situ como invasivos. Tais achados podem refletir aumento da acuracia do diagnostico, em virtude da maior quantidade de material e/ou melhor selecao radiologica das biopsias obtidas por agulhas 12, pela utilizacao coincidente da mamografia digital em campo limitado (estereotaxia digital).

Underestimation of malignancy of core needle biopsy for nonpalpable breast lesions

TL;DR: Core biopsy guiada por imagem e um procedimento confiavel, contudo permanece a recomendacao de resseccao cirurgica de lesoes de alto risco detectadas a biopsia de fragmento, mais importantes que o numero de fragmentos.

Ductal carcinoma in situ in core needle biopsies and its association with extensive in situ component in the surgical specimen.

TL;DR: There is direct relationship between extensive intraductal component in the surgical specimen when the core biopsy shows 45% or more of the DCI or microinvasive in the material examined.

Core biopsy no diagnóstico das lesões mamárias impalpáveis na categoria mamográfica BI-RADS® 5

TL;DR: In this article, the authors determine associacao entre alteracoes mamograficas classificadas na categoria BI-RADS® 5 (lesoes altamente suspeitas de malignidade) and diagnostico histopatologico em material obtido by core biopsy estereotaxica.

Nonpalpable breast lesions: stereotactic automated large-core biopsies.

TL;DR: The results of this study suggest that the use of 14-gauge needles improves agreement between surgical and needle core biopsy findings and that stereotactic biopsy with an automated needle and gun can be an acceptable alternative to surgical biopsy in women with mammographically suspicious breast lesions.

Stereotactic breast biopsy with a biopsy gun.

TL;DR: With greater experience, stereotactic-guided large-gauge automated percutaneous biopsy may prove to be an acceptable alternative to surgical biopsy in women with breast masses suspected at mammography.

Stereotactic breast biopsy of atypical ductal hyperplasia and ductal carcinoma in situ lesions: improved accuracy with directional, vacuum-assisted biopsy.

TL;DR: Directional, vacuum-assisted biopsy resulted in statistically significantly fewer cases of ADH or DCIS underestimation of disease without clinical complications or the creation of postbiopsy mammographic lesions.

Stereotaxic 14-gauge breast biopsy: how many core biopsy specimens are needed?

TL;DR: Stereotaxic 14-gauge core biopsy achieved a 99% diagnostic yield with five specimens for masses, and additional specimens may be necessary to diagnose some calcified lesions.

Atypical ductal hyperplasia: histologic underestimation of carcinoma in tissue harvested from impalpable breast lesions using 11-gauge stereotactically guided directional vacuum-assisted biopsy.

TL;DR: Because ADH was underdiagnosed in 25% of the lesions, it is recommended that surgical excision be performed whenever ADH is found in tissue obtained from 11-gauge directional vacuum-assisted breast biopsy.
