To determine the accuracy of using a regular mammographic table with an add-on device for biopsy of nonpalpable breast lesions in women in a community hospital setting.
During a 3-year period, 70 consenting women (39-80 years of age) with a nonpalpable mammographically suspicious lesion on routine screening mammography underwent 14-gauge automated percutaneous core biopsies, immediate needle localization and lumpectomy. The needle and surgical biopsy results were independently classified into 1 of 5 categories: cancer, fibroadenoma, fibrocystic change, normal or other.
The procedure was well tolerated, and all core specimens yielded adequate tissue for pathologic evaluation. There were 3 episodes of vasovagal reaction. There was complete agreement in histologic findings in 64 cases (91%), including 22 of 24 cancers (92%). The overall agreement for categorizing lesions was 91% (kappa = 0.88), and there was 97% agreement (kappa = 0.94) for the classification of cancer versus benign lesion.
The results are similar to those of studies performed with dedicated prone equipment. Stereotaxic core biopsies can be done safely and accurately in a community hospital setting with relatively inexpensive nondedicated mammographic equipment.
确定在社区医院环境中，使用配备附加装置的常规乳腺摄影台对女性不可触及乳腺病变进行活检的准确性。
在3年期间，70名年龄在39至80岁之间、在常规筛查乳腺摄影中发现有不可触及的可疑病变且表示同意的女性接受了14号自动经皮芯针活检、即时针定位和肿块切除术。针吸活检和手术活检结果被独立分为以下5类之一：癌症、纤维腺瘤、纤维囊性变、正常或其他。
该操作耐受性良好，所有芯针标本均获得了足够用于病理评估的组织。发生了3次血管迷走神经反应。64例（91%）的组织学检查结果完全一致，其中24例癌症中有22例（92%）。病变分类的总体一致性为91%（kappa = 0.88），癌症与良性病变分类的一致性为97%（kappa = 0.94）。
结果与使用专用俯卧位设备进行的研究相似。在社区医院环境中，使用相对便宜的非专用乳腺摄影设备可以安全、准确地进行立体定向芯针活检。
