To analyze the malignancy rate of ultrasound-guided core needle biopsy (US-CNB) for screen-detected breast lesions and to evaluate the results according to the mode of detection of the target lesions.
This is a retrospective review of 703 consecutive women who underwent US-CNB for screen-detected breast lesions at a single tertiary hospital. Breast Imaging Reporting and Data System (BI-RADS) categories and histopathological results of the target lesions were assessed. The cases were divided into two groups: the mammography-based detected lesions (M-group) and the US-based detected lesions (U-group). The biopsy performances of the two groups were compared using the χ test.
The malignancy rate in the entire population was 22.0%: 0.8%, 12.3%, 65.2%, 89.3%, and 94.6% in BI-RADS categories 3, 4A, 4B, 4C, and 5, respectively. The malignancy rate was significantly higher in the M-group (54.1% [79/146]) than in the U-group (13.6% [76/557]) (p < 0.001). BI-RADS category 3 was the most common assessment overall that led to a US-CNB (362/703, 51.5%) and the rate of BI-RADS category 3 diagnoses that led to US-CNB was significantly higher in the U-group (p < 0.001).
The malignancy rate associated with US-CNB for screen-detected breast lesions was 22.0%. The breast lesions detected by mammography have a higher malignancy rate than those detected by US. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 45:261-266, 2017.
分析超声引导下粗针穿刺活检（US-CNB）筛查出的乳腺病变的恶性率，并根据目标病变的检测方式评估结果。
这是一项对在一家三级医院接受US-CNB筛查乳腺病变的703例连续女性患者的回顾性研究。评估目标病变的乳腺影像报告和数据系统（BI-RADS）分类及组织病理学结果。病例分为两组：基于乳腺X线摄影检测出的病变（M组）和基于超声检测出的病变（U组）。采用χ检验比较两组的活检表现。
总体人群的恶性率为22.0%：在BI-RADS 3、4A、4B、4C和5类中分别为0.8%、12.3%、65.2%、89.3%和94.6%。M组的恶性率（54.1% [79/146]）显著高于U组（13.6% [76/557]）（p < 0.001）。BI-RADS 3类是总体上导致进行US-CNB的最常见评估类别（362/703，51.5%），且导致进行US-CNB的BI-RADS 3类诊断率在U组显著更高（p < 0.001）。
US-CNB筛查出的乳腺病变的恶性率为22.0%。乳腺X线摄影检测出的乳腺病变比超声检测出的病变具有更高的恶性率。© 2016威利期刊公司。《临床超声杂志》45:261 - 266，2017年。
