“…Sensibility, specificity, and accuracy of CNB has been described for palpable (93.6%, 88.7%, and 90.8% respectively) and not palpable lesions (94.5%, 87.8%, and 90.5%) 13 . A Brazilian study evaluated 88 patients submitted to VAB and posterior excisional biopsy, where US-guided VAB sensibility was of 84.2%, specificity of 100%, PPV of 100%, and NPV of 98% 14 . Comparing the results of our study, US-guided CNB with metal clip placement has a higher sensibility than US-guided VAB and a higher specificity and accuracy than US-guided CNB.…”

Introduction: Breast cancer screening has enhanced early–stage diagnosis by detection of impalpable tumors which require histopathological evaluation. Main percutaneous biopsy types are core-needle biopsy (CNB) and vacuum-assisted biopsy (VAB). CNB is less invasive and related to less bleeding and pain. VAB allows larger tissue samples and permits metal clip placement in biopsy bed for posterior localization in case of surgery. Access to VAB is restricted in Brazil due to its high costs. Objectives: To evaluate the agreement between pathological results of ultrasound (US) guided CNB with metal clip placement and surgery and settle false negative rates (FNR), sensibility, specificity, and accuracy of this method, for breast lesions < 20 mm. Methods: 388 US-guided CNB were retrospectively reviewed. Results: Surgical excision was performed in 317 patients. Overall FNR was 9.8%, (5.2% for lesions 10–20 mm), sensibility 90.2% (94.8% for lesions 10–20 mm), specificity 94.9% (94.1% for lesions 10–20 mm), and accuracy 91.1% (94.7% for lesions 10–20 mm). Cost of VAB varies from 2.2 to 12.5 times US-guided CNB. With metal clip placement, VAB costs 1.95 to 5.2 times US-guided CNB. Conclusions: For lesions that can be identified in US, CNB with metal clip placement has high sensitivity, specificity, and accuracy, as well as low FNR.
