PURPOSE
This study aims to evaluate the effectiveness of breast magnetic resonance imaging (MRI) in detecting residual breast cancer in patients after vacuum-assisted breast biopsy (VABB).
METHODS
Between 2012 and 2019, 26 patients with breast cancer who underwent VABB were enrolled. Breast MRI was conducted after VABB. Imaging findings were then compared with the histopathological results. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated.
RESULTS
Residual cancer was confirmed histologically in 8 of the 26 patients after VABB. The overall sensitivity, specificity, PPV, NPV, and accuracy of MRI for diagnosing residual cancer were 79.9%, 73.0%, 87.1%, 61.3%, and 77.8%, respectively. The sensitivity and NPV improved to 100%, when the number of biopsy specimens was larger than five.
CONCLUSION
Breast MRI showed high sensitivity and NPV in detecting residual breast tumor after VABB.
目的
本研究旨在评估乳腺磁共振成像（MRI）在真空辅助乳腺活检（VABB）后检测乳腺癌残留的效果。
方法
2012 年至 2019 年间，共纳入 26 例接受 VABB 的乳腺癌患者。VABB 后行乳腺 MRI 检查，将影像学结果与组织病理学结果进行比较。计算灵敏度、特异度、阳性预测值（PPV）、阴性预测值（NPV）和准确率。
结果
VABB 后 8 例患者经组织学证实存在残留癌。MRI 诊断残留癌的总灵敏度、特异度、PPV、NPV 和准确率分别为 79.9%、73.0%、87.1%、61.3%和 77.8%。当活检标本数大于 5 个时，灵敏度和 NPV 提高至 100%。
结论
乳腺 MRI 对 VABB 后检测乳腺肿瘤残留具有较高的灵敏度和 NPV。
