The Revisited Role of Ultrasound Guided Core Needle Biopsy in the Breast Cancer Diagnosis
Chirurgia (Bucharest, Romania : 1990)
Core needle biopsy (CNB) is an alternative to surgical biopsy in establishing the histopathological diagnosis of mammary lesions. The aim is to determine the accuracy of ultrasound guided CNB (US-CNB) in establishing breast cancer diagnosis. We retrospectively analyzed the data of US-CNB patients between May 2012 - December 2014. One hundred sixty-three biopsies were performed in 155 patients. To assess the diagnostic accuracy of US-CNB, the results were correlated with the gold-standard of surgical excision of the breast lesions, thus, 90 patients (94 breast lesions) were included in the study group. We calculated the concordance of the results using the Kappa Coefficient, sensitivity and specificity using the ROC curve and the false-negative rate. US-CNB identified 74 (79%) malignant lesions, 1 (1%) precursor high-risk lesion, and 19 (20%) benign lesions. Concordance between histopathological results was 96.8% (kappa: 0.91). The 94.2% (kappa: 0.80) consensus of the histological ty...
Ultrasound-Guided Core-Needle Biopsy of Suspicious Breast Lesions
Journal of Interdisciplinary Medicine, 2020
Background: Breast cancer is the female cancer with the highest mortality. While early detection is a public health priority in Western European countries, a screening program in our country has yet to be implemented. The best diagnostic accuracy is achieved through the use of triple assessment: clinical examination, imaging, and core-needle biopsy where indicated. Prognosis is influenced by clinical, histological, and biological factors, and therapy is most effective when individually tailored. Aim of the study: To analyze the clinical, histological, and immunohistochemical characteristics of the biopsied nodules and summarize our experience from the last three years. Material and Methods: We retrospectively analyzed data from 137 patients who underwent core-needle biopsy between 2017 and 2019. Imaging score was assigned based on ultrasound examination or mammography. Clinical and pathological parameters were recorded, followed by statistical processing of the data. Results: The me...

Background: Ultrasound-guided diagnostic breast biopsy technology represents the current standard of care for the evaluation of indeterminate and suspicious lesions seen on diagnostic breast ultrasound. Yet, there remains much debate as to which particular method of ultrasound-guided diagnostic breast biopsy provides the most accurate and optimal diagnostic information. The aim of the current study was to compare and contrast the 8gauge vacuum-assisted biopsy approach and the spring-loaded 14-gauge core biopsy approach. Methods: A retrospective analysis was done of all ultrasound-guided diagnostic breast biopsy procedures performed by either the 8-gauge vacuum-assisted biopsy approach or the spring-loaded 14-gauge core biopsy approach by a single surgeon from July 2001 through June 2009. Results: Among 1443 ultrasound-guided diagnostic breast biopsy procedures performed, 724 (50.2%) were by the 8-gauge vacuum-assisted biopsy technique and 719 (49.8%) were by the spring-loaded 14-gauge core biopsy technique. The total number of false negative cases (i.e., benign findings instead of invasive breast carcinoma) was significantly greater (P = 0.008) in the spring-loaded 14-gauge core biopsy group (8/681, 1.2%) as compared to in the 8-gauge vacuum-assisted biopsy group (0/652, 0%), with an overall false negative rate of 2.1% (8/386) for the spring-loaded 14-gauge core biopsy group as compared to 0% (0/148) for the 8-gauge vacuum-assisted biopsy group. Significantly more (P < 0.001) patients in the spring-loaded 14-gauge core biopsy group (81/719, 11.3%) than in the 8-gauge vacuum-assisted biopsy group (18/724, 2.5%) were recommended for further diagnostic surgical removal of additional tissue from the same anatomical site of the affected breast in an immediate fashion for indeterminate/inconclusive findings seen on the original ultrasound-guided diagnostic breast biopsy procedure. Significantly more (P < 0.001) patients in the spring-loaded 14-gauge core biopsy group (54/719, 7.5%) than in the 8-gauge vacuum-assisted biopsy group (9/724, 1.2%) personally requested further diagnostic surgical removal of additional tissue from the same anatomical site of the affected breast in an immediate fashion for a benign finding seen on the original ultrasound-guided diagnostic breast biopsy procedure. Conclusions: In appropriately selected cases, the 8-gauge vacuum-assisted biopsy approach appears to be advantageous to the spring-loaded 14-gauge core biopsy approach for providing the most accurate and optimal diagnostic information.
Diagnostic accuracy of ultrasonography-guided core needle biopsy for breast lesions
Singapore medical journal, 2012
This study aimed to assess the diagnostic accuracy of ultrasonography (US)-guided core needle biopsy (CNB) for breast lesions. We performed US-guided CNB of 733 lesions in 674 women from January 2003 to December 2005. Surgical excision was performed on 331 lesions. We compared the histopathologic findings of the CNB specimens with those of surgical specimens or with patients' long-term follow-up images. We also calculated the agreement, underestimation, sensitivity and false-negative rates. The CNB results showed 334 breast cancers (46%), 28 high-risk lesions (5%) and 367 benign lesions (50%). Four (1%) lesions were categorised as inconclusive. The final diagnosis was breast cancer in 348 lesions. The kappa measure of agreement between the US-guided CNB results and surgical excision findings or follow-up results was 0.861 (p-value < 0.001). The underestimation rate was 40% (10 out of 25) for atypical ductal hyperplasia and 47% (14 out of 30) for ductal carcinoma in situ (DCIS...
An update on core needle biopsy for radiologically detected breast lesions
Cancer, 1996
BACKGROUND. Traditionally, radiologically detected lesions of the breast have been evaluated by open surgical biopsy with wire localization. Recently, core needle biopsy has been introduced as an alternative to open surgical biopsy. The authors evaluated their own results with long term follow-up after core needle biopsy and reviewed the experience of other physicians with this new technique.

Our study evaluates the diagnostic accuracy of breast ultrasonography-guided core-needle biopsy (US-CNB) comparing smaller needles (16-gauge and 18-gauge) with 14-gauge (G) needle. 1118 US-CNB were retrospectively reviewed and no differences were observed in diagnostic accuracy parameters among the three needle size groups. US-CNB performed with smaller needles is a valid alternative to 14G US-CNB for assessing suspicious breast lesions.
Ultrasound-guided core needle biopsy of the breast: does frozen section give an accurate diagnosis?
Breast Cancer Research and Treatment, 2007
Reducing the period of uncertainty between the discovery of a breast tumor and histological diagnosis alleviates the psychological impact of breast cancer to an important degree. We aimed to verify whether histological results obtained with frozen sections of core needle biopsies (CNBs) offer an accurate and reliable tool for minimising this period. In 2619 cases we compared histological diagnosis on frozen sections with those on paraffin sections of CNB and finally with the results of open biopsies. Of the cases 49% were proved malignant and 51% benign. In 99.3% of the malignant lesions preceding CNB was correctly classified as B5 (n = 1185, 92.9%) or at least B4 (n = 82, 6.4%) in frozen and in paraffin sections. There were seven false-negative cases in frozen (false-negative rate = 0.5%) and five false-negative cases (falsenegative rate = 0.4%) in paraffin sections of CNB. On frozen sections complete sensitivity was 99.5% and the positive predictive value of B5 was 99.9%. There was one false-positive case in frozen sections and one in paraffin sections. False-positive rate = 0.08%, negative predictive value for B2 = 99.4% for frozen and 99.6% for paraffin sections; full specificity was 85.9 for frozen and 85.8 for paraffin sections of CNBs. Immediate investigation of CNB in frozen sections is an accurate diagnostic method and an important step in reducing psychological strain on patients with breast tumors and may be offered by specialised Breast Assessment Units.

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 ...

Introduction: Core needle biopsy (CNB) has progressively replaced fine needle aspiration cytology (FNAC) in the diagnosis of breast lesions. Less information is available on how these tests perform for biopsy of ultrasound (US) visible breast lesions. This study examines the outcomes of CNB and FNAC in a large series ascertained with surgical histology or clinical-imaging follow-up. Materials and methods: Retrospective five-year audit of 3233 consecutive US-guided needle samplings of solid breast lesions, from self-referred symptomatic or asymptomatic subjects, performed by six radiologists in the same time-frame (2003e2006): 1950 FNAC and 1283 CNB. The probability of undergoing CNB as a first test instead of FNAC was evaluated using logistic regression. Accuracy and inadequacy were calculated for each of CNB and FNAC performed as first test. Accuracy measures included equivocal or borderline/atypical lesions as positive results. Results: The probability of CNB as a first test instead of FNAC increased significantly over time, when there was a pre-test higher level of suspicion, in younger (relative to older) women, with increasing lesion size on imaging, and for palpable (relative to impalpable) lesions. Inadequacy rate was lower for CNB (B1 ¼ 6.9%) than for FNAC (C1 ¼ 17.7%), p < 0.001, and specifically in malignant lesions (B1 ¼ 0.9% vs. C1 ¼ 4.5%; p < 0.001). False negative rate was equally low for both CNB and FNAC (1.7% each test). CNB performed significantly better than FNAC for absolute sensitivity (93.1% vs. 74.4%; p < 0.001) and complete sensitivity (97.4% vs. 93.8%; p ¼ 0.001), however specificity was lower for CNB than FNAC (88.3% vs. 96.4%; p < 0.001). Absolute diagnostic accuracy was higher for CNB than FNAC (84.5% vs. 71.9; p < 0.001) while FNAC performed better than CNB for complete diagnostic accuracy (95.4% vs. 93.2; p < 0.008). In the small subgroup assessed with CNB after an inconclusive initial FNAC (231 cases) there was improved complete sensitivity (from 93.8% to 97.0%) however this also increased costs. Conclusion: FNAC and CNB were generally performed in different patients, thus our study reported indirect comparisons of these tests. Although FNAC performed well (except for relatively high inadequacy), CNB had significantly better performance based on measures of sensitivity, but this was associated with lower specificity for CNB relative to FNAC. Overall, CNB is the more reliable biopsy method for sonographically-visible lesions; where FNAC is used as the first-line test, inadequate or inconclusive FNAC can be largely resolved by using repeat sampling with CNB.
