[PMID: 36238918 PMCID: PMC9550630 DOI: 10.3348/jksr.2021.0082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/08/2021] [Revised: 07/13/2021] [Accepted: 08/26/2021] [Indexed: 06/16/2023]
Abstract
Purpose To evaluate the performance of MicroPure US imaging to detect and characterize microcalcifications. Materials and Methods A total of 171 lesions with suspicious microcalcifications seen on mammography and B-mode US were included and simultaneously evaluated using MicroPure US imaging. The size of microcalcifications was divided into small (punctate, amorphous, fine pleomorphic, and fine linear) and large (coarse heterogeneous), and the extent was divided into narrow (grouped) and wide (others). MicroPure US imaging visibility was divided into four types based on the number of microcalcifications on the two images: B > M (more on B-mode), B = M (similar), B < M (more on MicroPure), and negative. Triple pairwise comparison was used to evaluate the imaging features according to the MicroPure US imaging visibility. Results Among the 171 lesions examined, 157 lesions (91.8%) were detected by MicroPure US imaging. The proportion of Breast Imaging Reporting and Data System (BI-RADS) category 4A was significantly higher in the MicroPure positive group, and that of category 4B was significantly higher in the MicroPure negative group (p = 0.035). The other imaging features did not differ. Among the positive MicroPure subgroups, all features showed no significant difference. Conclusion MicroPure US imaging demonstrated 91.8% positivity in detecting microcalcifications on B-mode US. MicroPure US imaging visibility correlated with the BI-RADS category of microcalcifications.

Abstract
Stereotactic vacuum-assisted biopsy (SVAB) is an alternative method of breast biopsy for nonpalpable lesions detected by mammography. Considering the diagnostic effectiveness, a direct comparison of SVAB and open surgical biopsy (OSB) is lacking. We performed a retrospective review of 276 (33.8%) SVAB and 541 (66.2%) OSB to compare the diagnostic accuracy and the total number of procedures the patients underwent. The negative predictive values of OSB and SVAB were 99.77% and 99.61%, and their false-negative rates were 0.96% and 4.76%, respectively. SVAB, as the first-line biopsy method, obviated 92.3% of operations. All malignancies diagnosed using SVAB could be treated with single therapeutic surgery. By contrast, 48% of malignancies of OSB group received two operations. Breast Imaging Reporting and Data System (BI-RADS) category used at the study correlated well with the percentage of malignancy and can thus be used to predict biopsy results. Our study concluded that SVAB is reliable for diagnosing nonpalpable breast lesions and is the better biopsy method for categories 3 and 4A lesions, which reduces the benign surgery rate. For lesions with a higher likelihood of malignancy, BI-RADS 4B, 4C and 5, SVAB has an advantage over OSB, which lowers the total number of operations for malignancy treatment.

Abstract
Aims and background The purpose of the study was to identify clinical, mammographic or sonographic abnormalities of the male breast that require histological characterization. Methods and study design Clinical and imaging features of 31 male patients with breast lesions were retrospectively evaluated and correlated with core needle biopsy results. Results Seven of 31 (22.6%) lesions proved to be malignant and 24 of 31 (77.4%) benign, with a benign/malignant ratio of 4.4:1. In the case of a suspicious clinical presentation (firm mass, nipple retraction) and/or the presence of risk factors for breast cancer (BRCA2 mutation, previous breast cancer), core needle biopsy always demonstrated malignancy. All malignant lesions identified on mammography (4 of 7) appeared as a mass. Benign lesions detected on mammography (21 of 24) presented as an area of increased density (20 of 21) more frequently than a mass (1 of 21). Conclusions Sonographic features of cancers were not different from those of benign lesions. Clinical and mammographic findings, along with patient history, can be useful in the identification of male breast lesions that require core needle biopsy.

Abstract
The utility and reliability of assessing molecular biomarkers for translational applications on pre-operative core biopsy specimens assume consistency of molecular profiles with larger surgical specimens. Whether DNA methylation in ductal carcinoma in situ (DCIS), measured in core biopsy and surgical specimens are similar, remains unclear. Here, we compared genome-scale DNA methylation measured in matched core biopsy and surgical specimens from DCIS, including specific DNA methylation biomarkers of subsequent invasive cancer. DNA was extracted from guided 2mm cores of formalin fixed paraffin embedded (FFPE) specimens, bisulfite-modified, and measured on the Illumina HumanMethylation450 BeadChip. DNA methylation profiles of core biopsies exhibited high concordance with matched surgical specimens. Within-subject variability in DNA methylation was significantly lower than between-subject variability (all P<2.20E-16). In 641 CpGs whose methylation was related with increased hazard of invasive breast cancer, lower within-subject than between-subject variability was observed in 92.3% of the study participants (P<0.05). Between patient-matched core biopsy and surgical specimens, <0.6% of CpGs measured had changes in median DNA methylation >15%, and a pathway analysis of these CpGs indicated enrichment for genes related with wound healing. Our results indicate that DNA methylation measured in core biopsies are representative of the matched surgical specimens and suggest that DCIS biomarkers measured in core biopsies can inform clinical decision-making.

Abstract
PURPOSE The aim of this study was to evaluate the 10-gauge vacuum-assisted stereotactic biopsy (VASB) of isolated Breast Imaging Reporting and Data System (BI-RADS) 4 microcalcifications, using histology and follow-up results. METHODS From January 2011 to June 2013, VASB was performed on 132 lesions, and 66 microcalcification-only lesions of BI-RADS 4 were included into our study. VASB was performed using lateral decubitis stereotaxy for all patients. Pathologic results of VASB and further surgical biopsies were reviewed retrospectively. Patients who were diagnosed to have benign lesions by VASB were referred for follow-up. VASB and surgical histopathology results were compared to determine the underestimation ratios. RESULTS Fifteen out of 66 lesions from 63 patients (median age, 47 years; range, 34-88 years) were identified as malignant by VASB. Pathological results after surgery revealed three cases of invasive ductal carcinoma among the 12 VASB-diagnosed ductal carcinoma in situ (DCIS) lesions, for a DCIS underestimation rate of 25%. The atypical ductal hyperplasia underestimation rate was 0% for the three lesions. The follow-up period was at least 10 months, with an average of 22.7 months for all patients and 21.2 months for patients with VASB-diagnosed benign lesions. None of the patients had malignancy during the follow-ups. The false-negative rate was 0% in the follow-up of 48 patients. CONCLUSION VASB should be the standard method of choice for BI-RADS 4 microcalcifications. This method obviates the need for a surgical procedure in 73% of BI-RADS 4 microcalcification-only patients.

Abstract
Our long-term goal was to investigate the potential of incorporating redox imaging technique as a breast cancer (BC) diagnosis component to increase the positive predictive value of suspicious imaging finding and to reduce unnecessary biopsies and overdiagnosis. We previously found that precancer and cancer tissues in animal models displayed abnormal mitochondrial redox state. We also revealed abnormal mitochondrial redox state in cancerous specimens from three BC patients. Here, we extend our study to include biopsies of 16 patients. Tissue aliquots were collected from both apparently normal and cancerous tissues from the affected cancer-bearing breasts shortly after surgical resection. All specimens were snap-frozen and scanned with the Chance redox scanner, i.e., the three-dimensional cryogenic NADH/Fp (reduced nicotinamide adenine dinucleotide/oxidized flavoproteins) fluorescence imager. We found both Fp and NADH in the cancerous tissues roughly tripled that in the normal tissues ( p < 0.05 ). The redox ratio Fp/(NADH + Fp) was ? 27 % higher in the cancerous tissues ( p < 0.05 ). Additionally, Fp, or NADH, or the redox ratio alone could predict cancer with reasonable sensitivity and specificity. Our findings suggest that the optical redox imaging technique can provide parameters independent of clinical factors for discriminating cancer from noncancer breast tissues in human patients.

Abstract
BACKGROUND In 1996, National Cancer Institute (NCI) proposed five categories for the diagnosis of breast cytology in order to bring a degree of uniformity to the diagnostic reporting. Of these, categories 3 and 4 were sparsely studied. AIMS The present study was undertaken for the evaluation of the fine needle aspiration cytology (FNAC) categories of C3 and C4 in the breast lump and its histopathological correlation. MATERIALS AND METHODS In the retrospective study, a total number of 728 FNACs were categorized according to the NCI; of these, 28 cases of category C3 and 65 cases of category C4 were compared with histopathological diagnoses. RESULTS On histopathological examination of category C3, 18 (64.3%) cases showed benign lesions and 10 (35.7%) cases showed malignancy and among the C4 category, benign lesions found in nine (13.8%) and malignancy found in 56 (86.2%) cases. There was a significant statistical difference between the number of benign and malignant diagnoses for cytological categories of C3 (64.3%) and C4 (86.2%) (P < 0.001). The sensitivity, specificity, positive predictive value, and negative predictive value of C4 category in the diagnoses of malignancy were 84.8%, 66.7%, 86.2%, and 64.3%, respectively. CONCLUSION FNAC of the breasts is a simple, cost-effective, accurate, quick, and relatively less painful procedure, and it continues to play an integral part in the management of breast lesions. Our study concluded that there was a statistically significant difference between the number of benign and malignant diagnoses for categories of C3 and C4.

Abstract
INTRODUCTION Percutaneous needle biopsy (PNB) is the standard of care for diagnosis of breast lesions. Rates of excisional biopsy for breast diagnosis in North America have been reported at approximately 35 %, although significant regional variation exists. A target rate of PNB for diagnosis of breast abnormalities is needed to facilitate quality improvement. We sought to describe the use of PNB in a referral practice, the clinical scenarios prompting PNB or surgical biopsy (SB), and the accuracy and rate of PNB to inform the ultimate development of a benchmark rate of PNB in breast diagnosis. MATERIALS AND METHODS Female patients age 18-90 years, referred to Sunnybrook Health Sciences Centre, a large teaching hospital affiliated with the University of Toronto, with a breast lesion prompting tissue diagnosis with SB and/or PNB between 2002 and 2009 were studied. Each biopsied lesion was characterized by method of biopsy: PNB, SB, or PNB followed by SB. For each lesion, we collected data on patient demographics and breast cancer risk, reason for referral, imaging characteristics (breast imaging-reporting and data system classification, full description, final impression before biopsy), and pathology from each biopsy method. We report concordance between the final impression pre-biopsy and the PNB diagnosis with final surgical diagnosis where applicable. RESULTS One thousand and twenty-six lesions were biopsied, 987 (96 %) with PNB. The benign:malignant ratio for the entire cohort was 1.2:1. Final impression was concordant with final pathology in 674/862 (78 %) and PNB diagnosis was concordant with SB pathology in 487/556 (88 %). The reasons for SB without PNB were required pathologic evaluation of the entire lesion (n = 19), patient choice (n = 5), other biopsy technique used (n = 6), technical (n = 4), planned mastectomy (n = 3), and enlarging mass (n = 2). 155/559 (28 %) of lesions without evidence of malignancy on PNB ultimately underwent SB. Papillary lesions and radial scars were more likely to undergo SB with or without prior PNB. Lesions deemed to be suspicious or malignant on final impression were more likely to be excised after a benign diagnosis at PNB. CONCLUSION The vast majority of lesions requiring tissue diagnosis can be accurately diagnosed with PNB. Benchmarks for rates of PNB of 90 % or greater may be considered for performance measurement in appropriate populations.

Abstract
BACKGROUND Minimally invasive breast biopsy (MIBB) is the procedure of choice for diagnosing breast lesions indeterminate for malignancy. Multihospital health care systems face challenges achieving systemwide adherence to standardized guidelines among surgeons with varying practice patterns. This study tested whether providing individual feedback about surgeons' use of MIBB to diagnose breast malignancies improved quality metric adherence across a large health care organization. STUDY DESIGN We conducted a prospective matched-pairs study to test differences (or lack of agreement) between periods before and after intervention. All analytical cases of primary breast cancer diagnosed during 2011 (period 1) and from July 2012 to June 2013 (period 2) across a multihospital health care system were reviewed for initial diagnosis by MIBB or open surgical biopsy. Open surgical biopsy was considered appropriate care only if MIBB could not be performed for reasons listed in the American Society of Breast Surgeons' quality measure for preoperative diagnosis of breast cancer. Individual and systemwide results of adherence to the MIBB metric during period 1 were sent to each surgeon in June 2012 and were later compared with period 2 results using McNemar's test of marginal homogeneity for matched binary responses. RESULTS Forty-six surgeons were evaluated on use of MIBB to diagnose breast cancer. In period 1, metric adherence for 100% of cases was achieved by 37 surgeons, for a systemwide 100% compliance rate of 80.4%. After notification of individual performance, 44 of 46 surgeons used MIBB solely or otherwise appropriate care to diagnose breast cancer, which improved systemwide compliance to 95.7%. CONCLUSIONS Providing individual and systemwide performance results to surgeons can increase self-awareness of practice patterns when diagnosing breast cancer, leading to standardized best-practice care across a large health care organization.

Abstract
BACKGROUND Vacuum-assisted core-needle biopsy (VAB) is increasingly used to perform breast biopsies instead of automated-gun core-needle biopsy (CNB). The significance of discordance between radiologic and pathologic findings has not been well established in the era of VAB predominance. This retrospective study was conducted to determine the rate of malignancy after surgical excisional biopsy (EXB) of these lesions at our two institutions. MATERIALS AND METHODS We reviewed medical records from January 2008-June 2013 to identify female patients who underwent EXB for a Breast Imaging-Reporting and Data System (BI-RADS) 4 or 5 lesions found to be benign and discordant on CNB. Clinicopathologic data were gathered, and analysis was performed using descriptive statistics. RESULTS A total of 8081 core biopsies were performed in the study timeframe. Six of 81 (7.4%) patients who had an EXB for a benign discordant breast lesion were found to have malignant pathology (two invasive, four in situ). Four of 63 (6.3%) lesions originally biopsied by VAB were upgraded, compared with 2 of 17 (11.8%) originally biopsied by CNB. There were no statistically significant differences in the rates of upgrade to malignancy when data were stratified by BI-RADS score or method of biopsy. CONCLUSIONS The overall rate of malignancy after EXB of benign discordant lesions was 7.4%. Despite the widespread adoption of VAB, EXB is still warranted for clarification of discordant radiologic-pathologic findings.

Abstract
BACKGROUND The increase in breast cancer awareness and widespread use of mammographic screening has led to an increased detection of (non-palpable) breast cancers that cannot be discovered through physical examination. One of the methods used in the diagnosis of these cancers is vacuum-assisted core biopsy, which prevents a considerable number of patients from undergoing surgical procedures. The aim of this study was to present the results of stereotactic vacuum-assisted core biopsy for suspicious breast lesions. MATERIALS AND METHODS Files were retrospectively scanned and data on demographic, radiological and pathological findings were recorded for patients who underwent stereotactic vacuum-assisted core biopsy due to suspicious mammographic findings at the Interventional Radiology Centre of the Florence Nightingale Hospital between January 2010, and April 2013. Statistical analysis was carried out using Pearson's Chi-square, continuity correction, and Fisher's exact tests. RESULTS The mean age of the patients was 47 years (range: 36-70). Biopsies were performed due to BIRADS 3 lesions in 8 patients, BIRADS 4 lesions in 77 patients, and BIRADS 5 lesions in 3 patients. Mammography elucidated clusters of microcalcifications in 73 patients (83%) and focal lesions (asymmetrical density, distortion) in 15 patients (17%). In terms of complications, 1 patient had a hematoma, and 2 patients had ecchymoses (3/88; 3.3%). The histopathologic results revealed benign lesions in 63 patients (71.6%) and malignant lesions in 25 patients (28.4%). The mean duration of the procedure was 37 minutes (range: 18-55). Although all of the BIRADS 3 lesions were benign, 22 (28.6%) of the BIRADS 4 lesions and all of the BIRADS 5 lesions were malignant. Among the malignant cases, 80% were in situ, and 20% were invasive carcinomas. These patients underwent surgery. CONCLUSIONS In cases where non-palpable breast lesions are considered to be suspicious in mammography scans, the vacuum-assisted core biopsy method provides an accurate histopathologic diagnosis thus preventing a significant number of patients undergoing unnecessary surgical procedures.

Histopathological correlation of atypical (c3) and suspicious (c4) categories in fine needle aspiration cytology of the breast. Int J Breast Cancer 2013; 2013:965498. [PMID: 24175096 PMCID: PMC3794549 DOI: 10.1155/2013/965498] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2013] [Accepted: 08/26/2013] [Indexed: 11/25/2022] Open
Abstract
Introduction. According to the National Cancer Institute (NCI) guidelines in 1996, breast lesions are categorized as C1 to C5 on fine needle aspiration (FNA) cytology. Very few studies are available in the English literature analyzing histopathology outcome of C3 (atypical, probably benign) and C4 (suspicious, probably malignant) lesions. Our study aims to correlate FNA cytology of breast lump diagnosed as C3 and C4 lesion with histopathological examination. Methods. During a period of 2 years, 59 cases of C3 and 26 cases of C4 were retrieved from total 1093 cases of breast FNA. All the cases were reviewed by two cytopathologists independently. The final 24 cases of C3 and 16 cases of C4 categories were correlated with histopathological diagnosis. Result. Among C3 category, 37.5% revealed malignant findings, whereas of C4 category, 87.5% were malignant on histopathology. This difference was statistically significant (P = 0.0017). Sensitivity, specificity, positive predictive values, and negative predictive value of C4 category in diagnosing breast malignancy were 60.8%, 88.2%, 87.5%, and 62.5%, respectively.
Conclusion. Although FNAC is simple, safe, cost-effective and accurate method for diagnosis of breast masses, one must be aware of its limitations particularly in C3 and C4 categories. Also, since both these categories carry different probabilities of malignancy and thus different management, we therefore, support maintaining C3 and C4 categories.

Abstract
Breast imaging has undergone many changes since the early years of mammography. Screening mammography is credited with contributing to the substantial decrease in breast cancer mortality through early detection. Screening mammography programs allow depiction of nonpalpable, suspicious findings requiring histologic evaluation, but most of which eventually are proved benign. Widespread acceptance of percutaneous breast biopsy techniques represents the most important practice-changing development in breast imaging. The radiologist now plays a vital role not only in the detection and evaluation of breast disease, but also in the diagnosis and management of breast cancer. Descriptions of the advantages of percutaneous breast biopsy and the techniques of performing breast intervention are the focus of this review.

Abstract
BACKGROUND The goal of this study was to determine the length of operative time and its effect on surgeon productivity with the use of intraoperative digital specimen mammography (IDSM) compared to standard specimen mammography (SSM). METHODS A retrospective chart review was performed on 344 consecutive patients from a single breast surgeon from 2003 to 2010. Operative time was compared between procedures using SSM vs IDSM. Surgeon productivity was evaluated by the number of wire-localized excisions performed prior to and after implementation of IDSM. RESULTS Two hundred thirty patients underwent SSM and 114 underwent IDSM. Average operative time in the SSM group was 78 minutes vs 68 minutes in the IDSM group (P < .0001). In the first 2 years after implementation of IDSM, the number of wire-localized excisions performed increased by 20%. CONCLUSIONS Operative times were significantly shorter with the use of IDSM vs SSM, and this was associated with an increase in surgeon productivity.

Trends in breast biopsies for abnormalities detected at screening mammography: a population-based study in the Netherlands. Br J Cancer 2013; 109:242-8. [PMID: 23695018 PMCID: PMC3708556 DOI: 10.1038/bjc.2013.253] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2013] [Revised: 04/26/2013] [Accepted: 04/26/2013] [Indexed: 01/07/2023] Open
Abstract
Background: Diagnostic surgical breast biopsies have several disadvantages, therefore, they should be used with hesitation. We determined time trends in types of breast biopsies for the workup of abnormalities detected at screening mammography. We also examined diagnostic delays. Methods: In a Dutch breast cancer screening region 6230 women were referred for an abnormal screening mammogram between 1 January 1997 and 1 January 2011. During two year follow-up clinical data, breast imaging-, biopsy-, surgery- and pathology-reports were collected of these women. Furthermore, breast cancers diagnosed >3 months after referral (delays) were examined, this included review of mammograms and pathology specimens to determine the cause of the delays. Results: In 41.1% (1997–1998) and in 44.8% (2009–2010) of referred women imaging was sufficient for making the diagnosis (P<0.0001). Fine-needle aspiration cytology decreased from 12.7% (1997–1998) to 4.7% (2009–2010) (P<0.0001), percutaneous core-needle biopsies (CBs) increased from 8.0 to 49.1% (P<0.0001) and surgical biopsies decreased from 37.8 to 1.4% (P<0.0001). Delays in breast cancer diagnosis decreased from 6.7 to 1.8% (P=0.003). Conclusion: The use of diagnostic surgical breast biopsies has decreased substantially. They have mostly been replaced by percutaneous CBs and this replacement did not result in an increase of diagnostic delays.

Abstract
The introduction of screening mammography has brought about a greater knowledge of early breast cancer characteristics. These improvements have led to a reduction in size of suspicious lesions and a shift from surgical to image-guided core needle biopsies (CNBs). Establishing correlation between histologic and imaging findings is required for accurate diagnosis. Currently, there are no standardized multidisciplinary protocols for evaluating such lesions. We correlated histologic and radiologic findings in mammographically detectable calcified lesions in CNBs using specially designed Path/Rad Tissue Trays (patent pending, University of Kansas). Evidence of calcification was analyzed in 440 with and without the use of tissue trays. After mammographic identification of the lesion, CNBs are harvested, placed in tissue trays, and x-rayed to confirm sampling of the lesion. Images of CNBs with calcifications are marked by the radiologists and sent to the pathologist along with the biopsies. Trays with CNBs are then placed into cassettes and sent to the laboratory where they are embedded without disturbing orientation. Identification and localization of targeted microcalcifications were accomplished by radiologists and pathologists in 68 of 71 cases when using the tissue trays compared with 292 of 369 without tissue trays. Confirmation of microcalcifications was accomplished after deeper sectioning into tissue blocks from discordant cases. In conclusion, a systematic approach is recommended to standardize reporting of calcifications. The use of Path/Rad Tissue Trays has created a level of concordance between pathologists and radiologists that previously did no exist. It improved diagnostic reliability, encouraged communication between pathologists and radiologists, and minimized false diagnoses and/or delays in cancer diagnosis.

Abstract
Needle biopsy is now the initial investigation of choice for the pre-operative diagnosis of breast lesions. This includes core needle biopsy (CNB) and vacuum-assisted biopsy (VAB) with or without radiologic assistance. The performance indices of both of these biopsy techniques were evaluated. In a large cohort of patients with breast lesions including 464 cases (285 CNB and 179 VAB), with confirmed outcomes, the diagnostic accuracy was compared using parameters including quantitation of the sampling based on the total number of cores taken, cores containing breast parenchyma, and cores with lesion; and non-epithelial changes including necrosis and calcification. CNB showed a 99% PPV, 94% NPV, 96% sensitivity, and 99% specificity, whereas VAB demonstrated a 100% PPV, 100% NPV, 100% sensitivity, and 100% specificity. The correct diagnosis in CNB was proportional to the number of cores extracted, whereas accuracy of VAB was independent of the total number of cores taken. There was a positive correlation between the presence of calcification and malignancy in CNB, but not detected under VAB. CNB and VAB were equally efficient in palpable lesions, in detecting necrosis, and calcification. Large calcification was found to be associated with malignancy in both CNB and VAB. In non-palpable lesions, VAB was more effective in the detection of calcification. The diagnostic accuracy of VAB appeared to be independent of number of cores sampled, whereas CNB required a minimum of 3-4 cores to achieve high diagnostic accuracy.

Abstract
The widespread use of breast imaging has resulted in the increased detection of clinically occult suspicious breast lesions. Between 1999 and 2004 the number of breast biopsies in the United States has increased steadily. The armamentarium of methods to biopsy suspicious breast lesions has also increased significantly since the early 1990s with technological advancements for both surgical breast biopsy and percutaneous image guided breast biopsies.

Abstract
We sought to evaluate the impact of needle core size and number of core samples on diagnostic accuracy and upgrade rates for image-guided core needle biopsies of the breast. A total of 234 patients underwent image-guided percutaneous needle biopsies and subsequent surgical excision. Large-core needles (9 gauge or less) were used in 14.5 per cent of cases and the remainder were performed with smaller core needles. More than four core samples were taken in 78.9 per cent of patients. In 71.8 per cent of cases, needle biopsy pathology matched surgical excision pathology. After surgical excision, upgraded pathology was revealed in 10.7 per cent of cases. Of 11 patients (52.4%) with benign needle core pathology who had upgraded final pathology on surgical excision, 10 had a Breast Imaging Recording and Data System score 4 or 5 imaging study. Lesions smaller than 10 mm were more likely to be misdiagnosed ( P = 0.01) or have upgraded pathology ( P = 0.009). Other predictors of upgraded pathology were patient age 50 years or older ( P = 0.03) and taking four or fewer core samples ( P = 0.003). Needle core size did not impact accuracy or upgrade rates. Surgeons should exercise caution when interpreting needle biopsy results with older patients, smaller lesions, and limited sampling. Discordant pathology and imaging still mandate surgical confirmation.

Abstract
Large-core needle biopsy (LCNB) is a common diagnostic tool used for breast lesions biopsy under free-hand or ultrasound guidance. In this paper, we have retrospectively studied on 1,431 patients who require histopathological diagnosis of breast lesions by LCNB in Tianjin Cancer Hospital from January 2008 to April 2009. The procedure used automated prone unit, biopsy gun, and 14-gauge or 16-gauge needle under free-hand or ultrasound guidance. The pathological diagnosis and classification (12 features) were independently evaluated by pathologists. The pathological findings showed that 989 (69.1%) was invasive carcinoma, 58 (4.1%) were ductal carcinoma in situ (DCIS), 20 (1.4%) were diagnosed as atypical ductal hyperplasia (ADH), and 124 cases were benign masses. The diagnostic accuracy, sensitivity, and specificity were 0.89, 0.88, and 0.98, respectively. This study suggested that LCNB is a useful histological technique for diagnosing invasive cancer, but may not be inaccurate in diagnosis of ADH and DCIS. For the latter, surgical excision may be necessary.

Abstract
OBJECTIVE To evaluate the diagnostic accuracy of the use of an ultrasonography (US)-guided vacuum-assisted biopsy for microcalcifications of breast lesions and to evaluate the efficacy of the use of US-guided vacuum-assisted biopsy with long-term follow-up results. MATERIALS AND METHODS US-guided vacuum-assisted biopsy cases of breast lesions that were performed between 2002 and 2006 for microcalcifications were retrospectively reviewed. A total of 62 breast lesions were identified where further pathological confirmation was obtained or where at least two years of mammography follow-up was obtained. These lesions were divided into the benign and malignant lesions (benign and malignant group) and were divided into underestimated group and not-underestimated lesions (underestimated and not-underestimated group) according to the diagnosis after a vacuum-assisted biopsy. The total number of specimens that contained microcalcifications was analyzed and the total number of microcalcification flecks as depicted on specimen mammography was analyzed to determine if there was any statistical difference between the groups. RESULTS There were no false negative cases after more than two years of follow-up. Twenty-nine lesions were diagnosed as malignant (two invasive carcinomas and 27 carcinoma in situ lesions). Two of the 27 carcinoma in situ lesions were upgraded to invasive cancers after surgery. Among three patients diagnosed with atypical ductal hyperplasia, the diagnosis was upgraded to a ductal carcinoma in situ after surgery in one patient. There was no statistically significant difference in the number of specimens with microcalcifications and the total number of microcalcification flecks between the benign group and malignant group of patients and between the underestimated group and not-underestimated group of patients. CONCLUSION US-guided vacuum-assisted biopsy can be an effective alternative to stereotactic-guided vacuum-assisted biopsy in cases where microcalcifications are visible with the use of high-resolution US.

Abstract
OBJECTIVE The purpose of this study was to report the occurrence of intraoperative loss of metallic marking clips placed during image-guided biopsy and to hypothesize the likely mechanism of this clinical problem. MATERIALS AND METHODS From January 2003 through December 2004, patients presenting for preoperative mammographic localization and operative excision of biopsy site marking clips were identified. Age, method of image-guided biopsy, number of excised specimens, and tissue diagnosis were determined. Specimen radiographs were used to identify cases of suspected intraoperative clip loss. Clips absent on specimen radiographs and postoperative mammograms were defined as lost intraoperatively. Biopsy site marking clips, surgical clips, and suction device apertures were measured. RESULTS In 78 surgical procedures performed during the study period, three (3.8%) of the patients experienced clip loss. Specimen radiographs confirmed the absence of clips in all submitted tissues. A median of four (range, three to five) separate biopsy specimens were excised among these three cases. A healing biopsy site from the stereotactic biopsy preceding the clip placement procedure was confirmed in all cases. Absence of the metallic clip was confirmed on postoperative mammograms. The apertures of two types of suction device were four and two times those of the biopsy clips. CONCLUSION Intraoperative loss of metallic clips placed at the conclusion of image-guided breast biopsy is unusual but can occur during subsequent surgical excision. Repeated inability to locate the clip on specimen radiographs after accurate preoperative localization should raise the suspicion that the target clip has been lost, not missed, during surgery, likely because of inadvertent removal of the clip with the suction device.

Abstract
OBJECTIVE The aim of this study was to evaluate the reliability of information obtained by core needle biopsy (CNB). METHODS We studied 111 women (112 lesions) with breast cancer who underwent CNB and subsequent surgical excision. Six factors (histological type, nuclear grade, histological grade, estrogen receptor (ER) status, progesterone receptor (PR) status, and human epidermal growth factor receptor-2 (HER2) status) were evaluated in a blinded fashion at CNB and at surgical excision. RESULTS The histological type at CNB correlated exactly with that of the excisional specimen in 83% (87/105) of the cases. Of the 45 in situ lesions at CNB, 16 (36%) were found to have invasive carcinoma at surgical excision. The difference between the specimens from CNB and those from surgery in terms of the absolute concordance rate and kappa statistic value were 61% with a fair kappa value (0.26) in the nuclear grade, 75% with a moderate kappa value (0.55) in the histological grade, 95% with an almost perfect kappa value (0.84) in ER, 88% with a substantial kappa value (0.70) in PR and 88% with a substantial kappa value (0.65) in HER2. Regarding the evaluation of nuclear and histological grades, a trend toward greater accuracy was observed when thicker specimens were used. CONCLUSIONS CNB provided reliable information on the histological type of invasive carcinoma. It also evaluated ER, PR and HER2 (only in cases where the score was 3+) accurately in spite of the limited quantity of the specimen obtained with the thin (16-gauge) needle.

Abstract
PURPOSE OF REVIEW Fine needle aspiration has been used for many years as a diagnostic tool for breast lesions, with high sensitivity and specificity. There is controversy as to whether this technique should be replaced by other diagnostic procedures such as core biopsy. This review aims to re-evaluate the usefulness of breast fine needle aspiration. RECENT FINDINGS During the past 10 years many institutions have replaced fine needle aspiration by core biopsy and related techniques such as vacuum-assisted core biopsy and advanced breast biopsy instrument action. Other institutions continue to use fine needle aspiration as a first line of investigation for breast lesions. This technique is especially useful in radiologically benign lesions and when combined with image guidance. The use of the 'triple test' (combined cytologic, clinical and radiologic findings) decreases false-negative and false-positive results. SUMMARY Fine needle aspiration continues to be an acceptable and reliable procedure for the preoperative diagnosis of breast lesions, particularly in developing countries, and when used as part of the 'triple test'. Accurate diagnosis requires experience in both aspiration technique and specimen interpretation. Clinicians should be mindful of the limitations of the technique. The choice between fine needle aspiration and core biopsy should be individualized for the patient.

Abstract
BACKGROUND Percutaneous imaging-guided core needle biopsy (CNB) is being used increasingly as an alternative to surgical biopsy for the diagnosis of breast lesions that are suspicious or highly suggestive of malignancy. The purpose of this study was to evaluate ultrasonographically (US) guided 18-gauge automated CNB with post-fire needle position verification (PNPV) in the assessment of US visible breast lesions. METHODS Biopsy of 235 US visible breast lesions was performed using US-guided 18-gauge core needles (18-GCN). After firing the biopsy needle, an image was obtained in the orthogonal plane to confirm the precise post-fire position of the needle track before removing the needle. Needle core diagnoses were compared with surgical diagnoses in 235 lesions subsequently surgically excised. RESULTS The median size of the lesions was 14 mm (range, 5-60 mm). Agreement between needle core and surgical diagnoses in the 235 lesions was 92% including 192 cancers, 28 benign lesions, and 3 high-risk lesions. In the remaining 12 discordant lesions, 4 were high-risk lesions and 8 were benign lesions. In all 8 benign lesions, imaging-histological discordance was present. The sensitivity of US guided 18-GCNB for breast cancer was 96% (199 of 207). In 71% (167/235) of the cases only one core with PNPV was made. No complications occurred. CONCLUSION US-guided 18-GCNB for sonographically-demonstrated discrete mass lesions with PNPV is an accurate core needle biopsy technique of breast cancer. During the course of tissue sampling, evaluating the post-fire needle tip position by obtaining an orthogonal view with ultrasonographic guidance is the key to predicting the yield regardless of the size of the needle or the number of core samples.

Abstract
Stereotactic biopsies are widely used for the diagnosis of breast lesions. Most biopsy devices require breast thickness of at least 25-30 mm with compression. We describe an alternative technique in order to perform excisional stereotactic-guided biopsies for very thin breasts using the prone stereotactic table. In the outpatient setting and with local anesthesia, this procedure can be performed by a radiologist, a surgeon, and a nurse. After conventional stereotactic localization, a fine needle is placed at the site of the lesion. Once the point is marked with a skin marker, a 25G x 16 mm needle is introduced. Then, a couple of stereotactic views are taken to confirm the correct position of the needle. Later, the surgeon excises the lesion guided by the needle. Additional radiographs of the specimen and the remaining breast tissue are obtained to ensure the accuracy of the procedure.

Abstract
Ultrasonographically (US) guided core needle biopsy is currently recognized as a reliable alternative to surgical biopsy for the histopathologic diagnosis of breast lesions. However, despite advances in biopsy devices and techniques, false-negative diagnoses are unavoidable and may delay the diagnosis and treatment of breast cancer. The most common reasons for false-negative diagnosis are (a) technical or sampling errors, (b) failure to recognize or act on radiologic-histologic discordance, and (c) lack of imaging follow-up after a benign biopsy result. Technical difficulties (eg, poor lesion or needle visualization, deeply located lesions, dense fibrotic tissue) cause inaccurate sampling but can be reduced by using modified standard techniques. Radiologic-histologic correlation is also of critical importance in US-guided core needle biopsy. Radiologic-histologic discordance occurs when the histologic results do not provide a sufficient explanation for the imaging features and indicates that the lesion may not have been sampled adequately, so that repeat biopsy is warranted. Appropriate follow-up imaging is invaluable; even patients with concordant benign findings after US-guided core needle biopsy are directed to undergo follow-up imaging because there may be delays in the recognition of false-negative findings. Optimization of technique, radiologic-histologic correlation, and postbiopsy follow-up protocols are recommended to reduce the occurrence of false-negative diagnosis at US-guided core needle biopsy performed by radiologists.

Abstract
Breast core needle biopsy (CNB) is used for sampling breast lesions in both the screening and diagnostic context. We present the accuracy of breast CNB from a consecutive series of 4035 core biopsies, using methods that minimise selection and verification bias. We calculate accuracy and underestimation of malignancy for both automated (14G) and directional vacuum-assisted (11G) CNB performed under stereotactic or sonographic guidance. Overall sensitivity of CNB is 94.2% (92.9-95.5%) and specificity is 88.1% (86.6-89.6%), positive and negative predictive values are 84.8% (82.9-86.7%) and 95.6% (94.6-96.6%), respectively. In sampling microcalcification, the overall underestimation of malignancy is 26.6% (22.9-30.3%): underestimation is significantly higher for automated CB relative to VAB (chi2 ((df = 1)) = 8.90 , P = 0.002), the absolute difference in underestimation being 14% (5-23%); sensitivity is higher for VAB than automated CB (chi2 ((df = 1)) = 3.28, P = 0.06) but specificity is significantly higher for automated CB (14G) relative to VAB (11G) (chi2 ((df = 1)) = 6.37, P = 0.01), and the overall accuracy of the two methods is similar. Sensitivity of CNB improved with experience (over time and in relation to caseload). Accuracy was not substantially affected by lesion palpability or image-guidance method, and was similar for both masses and calcification but lower for lesions depicted as distortions on mammography. Inadequacy was very low and decreased with greater operator caseload, and was not associated with core gauge or image-guidance method. False negatives occurred in 4.4% (3.4-5.4%) of cases, and where core histology was benign but discordant with (suspicious) imaging and/or clinical findings the likelihood of malignancy was 33.1% (18.5-47.7%), emphasising the importance of correlating all test information in breast diagnosis.

Abstract
There is little doubt that significant benefits can accrue from carrying out screening mammography of women aged 40–49 in the setting of a highly quality assured service delivery. This will best be achieved using digital mammography to maximise detection rates and trained and high volume reading expert radiologists to apply economic cushions of optimising specificity as well as sensitivity in addition to utilising modern and accurate assessment and tissue sampling techniques that have evolved.

Abstract
Image-guided breast tissue sampling has become an acceptable alternative to open surgical biopsy for nonpalpable lesions. Advantages of minimally invasive core biopsy compared to open surgical biopsy include lower cost, lower complication rates, and less cosmetic deformity for patients. However, false-negative core biopsies can occur. Thus the imaging of a breast lesion and the histologic result of the core biopsy must be carefully correlated. This involves communication between radiology and pathology.

Abstract
Recently, the incidence of non-palpable or noninvasive breast cancer has increased. Consequently, criteria for choosing procedures to obtain pathological materials had changed. Fine needle aspiration biopsy cytology (FNA) and core needle biopsy (CNB) are both reliable procedures for detecting breast cancer. However, for non-palpable lesions, the diagnostic accuracy of CNB is higher. The main limits of FNA are the high rate of insufficient sampling and inability to determine invasiveness. CNB is an established alternative to surgical biopsy, and CNB can avoid excess surgical biopsies in a large number of patients. In addition to accurate histological diagnosis, there is interest in obtaining prognostic information from CNB, especially for patients being considered for preoperative (neoadjuvant) therapy. CNB provides useful information about histologic type and grade. However, an unavoidable problem of CNB is underestimation of invasion. On the other hand, there is good concordance in particular for estrogen receptor (ER) and progesterone receptor (PR) between CNB and surgical excision. Several aspects of CNB remains controversial, such as diagnosing papillary lesions by CNB, problems regarding tumor cell displacement after CNB, and management of lobular neoplasia (LN) on CNB.

Abstract
PURPOSE To prospectively determine whether there is a minimum number of cores required for histopathologic diagnosis of mammographically detected nonpalpable breast lesions with an add-on 14-gauge stereotactic core-needle biopsy device. MATERIALS AND METHODS The study was approved by the ethics committee of the hospital; informed consent was obtained. Biopsy was performed in 197 patients with 205 lesions (97 masses, 108 microcalcifications). The first sample (from the center) was collected in container A; second and third samples (2 mm from center), in container B; and additional samples, in container C. Malignancies, atypical ductal hyperplasia (ADH), and radial scars were excised. Benign lesions were followed up mammographically (mean, 24 months). Strict sensitivity and working sensitivity were calculated separately. Stereotactic biopsy with diagnosis of a nonmalignant lesion that, after surgery, proved to be malignant was considered false-negative when strict sensitivity was calculated. Stereotactic biopsy with diagnosis of ADH or radial scar was considered true-positive if the findings at surgery corresponded to the results at biopsy or indicated malignancy and was considered false-positive if the findings at surgery were benign when working sensitivity was calculated. Sensitivity, specificity, and overall accuracy of stereotactic biopsy were determined for masses and microcalcifications in all three containers by using surgical samples and findings at mammographic follow-up as reference. At chi2 analysis, P < .05 was considered to indicate significant difference. RESULTS Strict sensitivity of the first sample was 77% (66 of 86) (90% [35 of 39] for masses, 66% [31 of 47] for microcalcifications). Results of the first sample were false-negative significantly more often in microcalcifications (n = 16) than in masses (n = 4) (P = .010). Combined results of containers A and B (ie, three samples) yielded higher strict sensitivity than those with first sample alone (95% [37 of 39] for masses [P = .196], 91% [43 of 47] for microcalcifications [P < .001]). With multiple samples, strict and working sensitivity were both 100% (39 of 39) for masses and 91% (43 of 47) and 98% (46 of 47), respectively, for microcalcifications. Four false-negative diagnoses (ADH, three cases; lesion with discordant mammographic and stereotactic biopsy findings, one case) were microcalcifications. CONCLUSION More than three samples are needed (a minimum number was not determined) for a histologic diagnosis of a mass lesion by using an add-on stereotactic biopsy device.

Abstract
PURPOSE The objective of this study was to examine the diagnostic accuracy of sonographically guided 14-gauge core-needle biopsy (CNB). METHODS Sonographically guided 14-gauge CNBs of 715 breast lesions were performed in 652 patients. Histopathologic results were correlated with imaging findings, and repeat biopsy was recommended in the cases of discordance between the radiologic and pathologic results. Long-term follow-up was used for patients with CNB findings of a benign lesion. RESULTS Sonographically guided CNB revealed malignancy in 311 lesions (43%). Thirty-one lesions with CNB findings indicating benign conditions underwent additional image-guided or excisional biopsy because of indeterminate pathologic features, disagreement between radiologic and pathologic results, surgeon preference, or patient request. Within these 31 cases, 9 malignancies were diagnosed. The duration of follow-up for the remaining 373 benign lesions varied from 27 to 60 months. In 3 of these 373 cases, carcinoma was diagnosed at the site of CNB. The false-negative rate of 14-gauge sonographically guided CNB was 3.7%, and the sensitivity of sonographically guided CNB for the diagnosis of breast cancer was 96.3%. CONCLUSIONS Sonographically guided 14-gauge CNB is a safe and accurate method for evaluating breast lesions that require tissue sampling. Radiologic-pathologic correlation and follow-up of benign lesions are essential for a successful breast biopsy program.
