In the women with compressed thin thickness (≦ 3 cm), mammographic guiding vacuum-assist breast biopsy (MG-VABB) is a technical challenge. We herein report their performance of MG-VABB on suspicious microcalcification by modern mammography.
We retrospectively reviewed the consecutive MG-VABB in our hospital from February 2019 to January 2021. All the patients received biopsy because of suspicious microcalcifications discovered by mammography and had at least one-year post-biopsy follow-up.
We reviewed 745 consecutive patients revealing 195 with compressed thin breasts ≦ 3 cm (mean age: 50.12 ± 7.0; breast thickness: 24.99 mm range 11.6-30 mm). Of the 191 patients received biopsy, the microcalcification retrieval rate was 97.9%. Using the half-open notch biopsy or horizontal needle approach, the biopsies were technically achieved in 30.4% and 9.4% of patients respectively. Regarding to the gold standard of surgicohistology, the cancer sensitivities was 88.46% and the atypia upgrade rate was 16.67%. There was no statistical difference of the procedure time between stereotactic guided and tomosynthesis guided.
The modern MG-VABB has technically improve the performance of biopsy to the patients with compressed thin breasts (≦ 3 cm), revealing approximate results to those breasts > 3 cm. The diagnosis helps the management of suspicious microcalcifications discovered by mammography.
在乳房厚度压缩至≦3cm 的女性中，乳腺 X 线摄影引导真空辅助乳腺活检（MG-VABB）是一项技术挑战。我们在此报告了现代乳腺 X 线摄影术发现可疑微钙化时，MG-VABB 在这些患者中的表现。
我们回顾性分析了 2019 年 2 月至 2021 年 1 月在我院进行的连续 MG-VABB。所有患者均因乳腺 X 线摄影发现可疑微钙化而接受活检，且至少有 1 年的活检后随访。
我们共回顾了 745 例连续患者，其中 195 例乳房厚度压缩至≦3cm（平均年龄：50.12±7.0；乳房厚度：24.99mm，范围 11.6-30mm）。在接受活检的 191 例患者中，微钙化的检出率为 97.9%。采用半开放式活检或水平针进路，分别有 30.4%和 9.4%的患者能够完成技术上的活检。根据手术组织学的金标准，癌症的敏感性为 88.46%，异型增生升级率为 16.67%。立体定向与断层合成引导的操作时间无统计学差异。
现代 MG-VABB 技术上提高了对乳房厚度压缩至≦3cm 患者的活检表现，与乳房厚度>3cm 的患者结果近似。该诊断有助于管理乳腺 X 线摄影术发现的可疑微钙化。
