Abstract
Background: Stereotactic breast biopsies have become the gold standard for tissue diagnosis in non-palpable, sonographically occult breast abnormalities seen on mammogram. Only limited data exist in South Africa on the correlation between imaging findings and stereotactic biopsy histology.Objectives: To describe the mammographic findings and histological diagnosis in patients who underwent stereotactic breast biopsy at a referral hospital. In addition, to evaluate the proportion of malignancy in each Breast Imaging Reporting and Data System (BI-RADS) category.Method: A retrospective review of stereotactic breast biopsies was performed. Imaging characteristics (including BI-RADS category) and histological diagnosis were recorded. Using histopathology, cases were classified as benign, high-risk or malignant.Results: A total of 131 biopsies, from 123 patients, were included in the study. Most biopsies were performed on asymptomatic patients (79.3%, 104/131). The majority were categorised as BI-RADS 4 and demonstrated calcifications. Histology revealed a malignant diagnosis in 40 (30.5%) patients, a high-risk lesion in 8 (6.1%) patients and a benign diagnosis in 83 (63.4%) patients. There was a stepwise increase in the proportion of malignancy from BI-RADS category 3 to 5. When compared with surgical histology, the stereotactic biopsies demonstrated an overall ductal carcinoma in situ (DCIS) underestimation rate of 10.3%.Conclusion: Despite resource restrictions, stereotactic breast biopsies performed in a South African context produce radiological-pathological concordance in keeping with BI-RADS guidelines, as well as with local and international studies.

Abstract
BACKGROUND Technical advances have improved the detection of small mammographic lesions. In the context of mammographic screening, accurate sampling of these lesions by percutaneous biopsy is crucial in limiting diagnostic surgical biopsies, many of which show benign results. METHODS Women undergoing core biopsy between January 1997 and December 2007 for <10-mm lesions are included. Patient demographics, imaging features and final histology were tabulated. Performance indices were evaluated. RESULTS This audit includes 803 lesions <10 mm. Based on core histology, 345 women (43.0%) were immediately cleared of malignancy and 300 (37.4%) were referred for definitive cancer treatment. A further 157 women (19.6%) required diagnostic surgical biopsy because of indefinite or inadequate core results or radiological-pathological discordance, and one woman (0.1%) needed further imaging in 12 months. The open biopsies were malignant in 46 (29.3%) cases. The positive predictive value of malignant core biopsy was 100%. The negative predictive value for benign core results was 97.7%, and the false-negative rate was 2.6%. The lesion could not be visualized after core biopsy in 5.1% of women and in 4.0% of women with malignant core biopsies excision specimens did not contain residual malignancy. Excessive delays in surgery because of complications of core biopsy were not reported. CONCLUSION Even at this small size range, core biopsy evaluation of screen-detected breast lesions is highly effective and accurate. A lesion miss rate of 3.1% and under-representation of lesions on core samples highlight the continued need for multidisciplinary collaboration and selective use of diagnostic surgical biopsy.

Abstract
OBJECTIVE The topic of imaging-guided breast interventions spans more than 30 years. Radiologists pioneered procedures such as needle or wire localization and ultrasound and stereotactic-guided biopsy. Using recently developed devices and technology, the opportunity exists to treat lesions of the breast with minimally invasive imaging-guided techniques. CONCLUSION Breast imagers and interventional radiologists, along with our surgical and oncologic colleagues, are best qualified to participate together in the research and development of these procedures.

Abstract
OBJECTIVE The purpose of our study was to evaluate tissue sampling methods used for MRI-detected suspicious contralateral breast lesions in the American College of Radiology Imaging Network (ACRIN) 6667 trial. MATERIALS AND METHODS Breast MRI was performed at 25 institutions in 969 women who had a recent diagnosis of unilateral breast cancer and negative contralateral mammography and clinical breast examinations. Biopsy was recommended for MRI findings in 135 women, and 121 underwent sampling. Frequencies and positive biopsy rates of sampling methods used for initial diagnosis and imaging guidance techniques were calculated and compared. RESULTS Sampling yielded 30 malignant and 91 benign results. Initial sampling used needle biopsy in 88 of 121 (72.7%) and surgical biopsy in 30 of 121 (24.8%) women. Surgical biopsy was excisional biopsy in 28 of 30 (93.3%) and mastectomy in two of 30 (6.7%). The remaining three of 121 (2.5%) women underwent mastectomy, but it was not documented whether this represented initial tissue sampling. Of imaging-guided procedures, 56 of 106 (52.8%) used MRI; 49 of 106 (46.2%), ultrasound; and one of 106 (1.0%), stereotaxis. MRI-guided sampling was with needle biopsy rather than wire-localized surgical biopsy in 33 of 56 (58.9%) women, whereas ultrasound used needle biopsy in 47 of 49 (95.9%). Positive biopsy rates of sampling methods were 20.5% for needle biopsy, 46.2% for excisional biopsy, and 0% for mastectomy. CONCLUSION The majority of initial biopsies for MRI-detected contralateral breast lesions used needle biopsy rather than surgical biopsy. Contralateral surgery could have been avoided in most cases had needle biopsy been performed because most excisional biopsy and all mastectomy results were benign. MRI-guided biopsy was significantly more likely than ultrasound-guided sampling to use wire-localized surgical biopsy rather than needle biopsy.

Abstract
Screening mammography performed annually on all women beginning at age 40 years has reduced breast cancer deaths by 30% to 50%. The cost per year of life saved is well within the range for other commonly accepted medical interventions. Various studies have estimated that reduction in treatment costs through early screening detection may be 30% to 100% or more of the cost of screening. Magnetic resonance imaging (MRI) screening is also cost-effective for very high-risk women, such as BRCA carriers, and others at 20% or greater lifetime risk. Further studies are needed to determine whether MRI is cost-effective for those at moderately high (15%-20%) lifetime risk. Future technical advances could make MRI more cost-effective than it is today. Automated whole-breast ultrasonography will probably prove cost-effective as a supplement to mammography for women with dense breasts.

Abstract
BACKGROUND Because benign postoperative changes may overlap those of malignancy, the utility of breast MRI following an excisional biopsy is unclear. We sought to investigate the ability of MRI to predict residual disease following an excisional biopsy for breast cancer. MATERIALS AND METHODS We reviewed 93 patients who underwent surgical treatment for stage 0-III breast cancer at our institution from January 2005 to May 2008. All patients had previously undergone excisional biopsy with subsequent MRI. Patient, tumor, and treatment characteristics were collected. Descriptive statistics were utilized for data summary and data were compared using Fisher's exact or χ(2) tests. RESULTS The mean age of the 84 patients who had additional surgery following MRI was 51 ± 7 y. Thirteen (15%) patients had only postoperative changes on MRI; six had residual disease on final pathology. Of 71 patients with MRI findings suspicious for residual disease, 54 (76%) had pathologic confirmation, while 17 (24%) had only benign pathology. The sensitivity and specificity of MRI following excisional biopsy were 90% and 29%, respectively. Overall, 49 (58%) of the 84 patients underwent mastectomy, including 11 of 24 (46%) with negative final pathology. Patient age, tumor size, tumor grade, biomarker profile, nodal status, and MRI findings were not predictive of surgical treatment type (P > 0.05). CONCLUSION Although excisional biopsy decreases the specificity of breast MRI, its sensitivity remains high. Nearly 50% of patients with a suspicious MRI and negative final pathology underwent mastectomy, suggesting that additional biopsy of all suspicious MRI findings is necessary to avoid surgical overtreatment.

Abstract
The purpose of this study was to analyze cases undergoing imaging guided localization prior to surgical excisional biopsy of abnormalities in the breast and to describe the methodology utilized to perform such presurgical localization procedures. Presurgical localization of non palpable breast abnormalities is a simple, safe and effective procedure; it is now used more selectively for this indication due to availability of minimally invasive percutaneous biopsy procedures that can be performed under ultrasound or stereotactic guidance.

Abstract
RATIONALE AND OBJECTIVES The aim of this study was to determine the sonographic visibility of implanted collagen-based breast biopsy marker clips in the clinic and operating room. MATERIALS AND METHODS Female patients aged > or =18 years who presented for preoperative surgical evaluation within 4 weeks of ultrasound-guided breast biopsy and collagen-based marker clip placement were eligible for this pilot study. The sonographic visibility of the marker clips was rated from 1 (not visible) to 5 (clearly visible) by surgeons at the preoperative appointment, by radiologists at wire localization, and by surgeons in the operating room. Visibility was considered inadequate for values of 1 or 2 and adequate for values of 3, 4, or 5. The data were compared using Wilcoxon's signed-rank test for paired differences across physician (radiologist vs surgeon), time (preoperative visit vs day of surgery), and target (lesion vs clip). RESULTS Twenty-five patients with 26 lesions were enrolled, and 19 patients returned for all imaging procedures. The mean lesion size was 12 mm (range, 5-24 mm). Adequate marker clip visibility assessed by the surgeons decreased from 80% (20 of 25) at the preoperative appointment to 65% (11 of 17) in the operating room, but the difference was not significant (P=.27). Visibilities of the lesions and clips were similar at the preoperative appointment (P=.61), but the clips were significantly less visible on the day of operation (P=.03). CONCLUSION The sonographic visibility of collagen-based marker clips is variable and likely decreases over time but may be adequate to guide intraoperative surgical excision in many cases.

Abstract
INTRODUCTION Obtaining negative margins for patients undergoing breast-conserving surgery (BCS) for invasive lobular carcinoma (ILC) can be difficult because of the unique histologic pattern of ILC. Our goal was to determine whether any specific patient- or disease-related factors influenced margin status. PATIENTS AND METHODS We retrospectively reviewed 211 patients with ILC treated from 1994 through 2004 to determine if specific clinical and pathologic factors influenced the ability to obtain negative margins. RESULTS We identified 110 patients (52%) who underwent total mastectomy and 101 (48%) who underwent BCS. Among patients who underwent BCS, 50 (50%) had close or positive margins. Patients with close or positive margins were more likely to have architectural distortion on ultrasonography (vs. mass or calcifications; P = .049), to have undergone excisional biopsy (vs. core or fine-needle aspiration; P = .008), and to have associated ductal carcinoma in situ (P = .021). On multivariate analysis, only biopsy method retained significance (P = .006). CONCLUSION Core needle biopsy is the preferred method of diagnostic biopsy before surgical intervention. With appropriate patient selection, most patients with early-stage ILC can undergo successful BCS.

Abstract
BACKGROUND Despite the advent of guidelines recommending core needle biopsy (CNB) for diagnosis of breast abnormalities, it is underused in some jurisdictions. We sought to determine those factors influencing surgeons' choices of breast biopsy techniques. METHODS We surveyed 385 general surgeons in Ontario to first determine factors influencing the choice of fine-needle aspiration biopsy (FNAB), CNB, both or neither for diagnosis of breast abnormalities in six clinical scenarios with varying risk of malignancy. Second, respondents were asked to rate 15 patient, organizational, and system factors for their impact on choice of biopsy technique. Third, surgeons were asked to describe their three greatest barriers to provision of cancer care. RESULTS Response rate was 44%, and 126 provided answers to the survey questions. When there was a high risk of malignancy, CNB and/or FNAB were favored over surgical biopsy (83% to 97% compared with 41% for presumed benign lesions), and CNB was preferred for percutaneous biopsy over FNAB (58% to 79% compared with 1% to 18%). Patient and clinical factors (46% FNAB, 42% CNB), patient preference for biopsy technique (34%, 31%), and delayed access to CNB, rather than lack of equipment (11% FNAB, 8% CNB) or expertise for CNB or FNAB (15%, 12%), had the greatest reported impact on choice of biopsy technique. CONCLUSIONS Surgeon preference for CNB is higher than actual use. Further research is needed to establish whether or how CNB use could be improved by support for shared decision making or facilitating access.

Abstract
BACKGROUND Ductal carcinoma in situ (DCIS) often requires some method of localization to achieve breast-conserving therapy. The purpose of this study was to compare the efficacy of intraoperative ultrasound versus mammographic needle localization (MNL) for partial mastectomy in DCIS. MATERIALS AND METHODS Data were collected from a Breast Cancer Surgery Database. All DCIS cases undergoing partial mastectomy (PM) were identified. Margin status, re-excision rates, and cost were determined for both groups. RESULTS A total of 155 patients undergoing PM for DCIS were identified from the database. In the 96 patients undergoing ultrasound-guided PM (Group 1), the positive margin rate was 10.4%, and close margins (<1 mm) were observed in 22.9% after initial surgery. There were 59 patients who underwent MNL (Group 2); the positive margin rate was 11.9%, and close margins were observed in 27.1%. The difference between positive and close margins in Group 1 versus Group 2 was not statistically significant. The rate of re-excision was 20.8% for Group 1 and 30.5% for Group 2, resulting in 1.23 and 1.37 operations per patient, respectively. The average cost of an intraoperative ultrasound at our institution was $933 and $1858 for MNL (excluding cost of radiologic interpretation), a difference of $925 per case. CONCLUSION Our study showed equivalent rates of positive margins and re-excision between intraoperative ultrasound and MNL when performing PM for nonpalpable DCIS. Considering the more invasive nature and increased cost of MNL, we consider surgeon-performed intraoperative ultrasound, when possible, the more cost-effective and practical procedure for patients with DCIS.

Abstract
BACKGROUND Preoperative diagnosis of breast cancer is a standard of care. We conducted a population-based study to determine the factors associated with the use of percutaneous needle biopsy to diagnose breast cancer in Ontario. METHODS We identified a total of 3644 women who underwent breast tissue sampling (percutaneous needle biopsy or surgical excision) that yielded a diagnosis of cancer between Apr. 1, 2002, and Dec. 31, 2002, and for whom we were able to obtain complete data. We performed univariate and multivariate analyses to examine the association between a number of variables and the use of percutaneous biopsy or surgery for diagnosis and the performance of biopsy with or without image guidance. The variables were age, local health integration network (LHIN), income quintile, urban or rural residence, access to a primary care provider, prior mammogram, prior regular screening mammography, screen-initiated biopsy, and surgeon and radiologist specialization in breast disease. RESULTS A total of 2374 women (65%) underwent percutaneous biopsy to diagnose breast cancer. The use of percutaneous biopsy varied from 22% to 81% among LHINs. On multivariate analysis, no patient variables were associated with the use of percutaneous biopsy for diagnosis. Only the LHIN and surgeon and radiologist specialization were predictive of whether a woman received a percutaneous biopsy. These 2 variables, along with income quintile and screen-initiated biopsy, were associated with the use of image-guided biopsy as the method of choice. CONCLUSION Geographic variation in the use of percutaneous biopsy, particularly image-guided biopsy, for the diagnosis of breast cancer exists across Ontario. The frequency of such biopsies may be a useful quality indicator. Strategies to improve uptake of organized evidence-based care may increase the use of percutaneous biopsy.

Quality assurance initiative at one institution for minimally invasive breast biopsy as the initial diagnostic technique. J Am Coll Surg 2008; 208:75-8. [PMID: 19228506 DOI: 10.1016/j.jamcollsurg.2008.09.008] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2008] [Revised: 08/23/2008] [Accepted: 09/09/2008] [Indexed: 10/21/2022]
Abstract
BACKGROUND In 2005, the American College of Surgeons Consensus Conference issued a statement about the diagnostic workup of image-detected breast abnormalities. Guidelines include use of image-guided percutaneous needle biopsy as the gold standard for diagnosing image-detected breast abnormalities. In this study, we evaluate a method to audit use of excisional biopsy among different breast surgeons at our institution. STUDY DESIGN From March to September 2007, 465 patients undergoing breast operation for benign or malignant lesions at our institution were interviewed by a surgical resident or physician's assistant. If an excisional biopsy was scheduled for initial diagnosis, the patient and surgeon were asked whose preference it was to perform the operation. Three attending groups were designated: academic breast surgeons, private practice breast surgeons on clinical faculty, and general surgeons who perform breast operations in addition to other procedures. Use of excisional biopsy was compared between these groups. RESULTS Compliance for preoperative interview completion was 79%, differing substantially between surgeon groups with rates of 91%, 74%, and 58% for the academic breast, private practice, and general surgeons, respectively. Excisional biopsy for diagnosis made up 10%, 35%, and 37% of the case load for academic breast, private practice, and general surgeons, respectively. Patient and surgeon agreed 85% of the time for preference of performing diagnostic excisional biopsies. CONCLUSIONS Excisional biopsies continue to be performed as the initial diagnostic procedure for 40% of patients. Tracking biopsy practices by surgeon can improve adherence with current recommendations.

Abstract
BACKGROUND Although breast-conserving therapy (BCS) is considered the standard of care for early-stage breast cancer, up to 20% of patients are dissatisfied. The effect of treatment-related factors on patient satisfaction with their healthcare experiences is unclear. METHODS All BCS patients at the University of Michigan Medical Center who were treated between January 2002 and May 2006 were surveyed (n=714; response rate, 79.5%). Patients were queried regarding 4 aspects of their decision for surgery: satisfaction with the decision, decision regret, decisional conflict, and trust in surgeons. Independent variables included the number of re-excisions, the occurrence of postoperative complications, and postoperative breast appearance, which was assessed by using the Breast Cancer Treatment and Outcomes scale. Multiple logistic regression was used to assess the effect of the independent variables on each outcome controlling for demographic and clinical characteristics. RESULTS Breast asymmetry after BCS was correlated significantly with patient satisfaction with their treatment experiences and patient distrust in surgeons. Women who reported pronounced asymmetry were significantly less likely to be satisfied with the decision for surgery compared with women who reported minimal asymmetry (odds ratio [OR], 0.43; 95% confidence interval [95% CI], 0.21-0.89). Women with pronounced asymmetry were less likely to be certain about their surgical decision (OR, 0.36; 95% CI, 0.21-0.60) and to believe that they were prepared to make the decision for surgery (OR, 0.25; 95% CI, 0.14-0.43). Increasing breast asymmetry was associated with higher surgeon distrust scores (2.14 vs 2.30 vs 2.35; P= .04) and with the occurrence of postoperative complications (distrust score: 2.23 vs 2.35; P= .03). Reoperation after BCS was not associated with patient satisfaction or trust in providers. CONCLUSIONS Esthetic result after BCS was associated more profoundly with aspects of satisfaction than either surgical therapy or the occurrence of postoperative complications. The current findings indicated that surgeons who care for patients with breast cancer should identify the women at an increased risk for breast asymmetry preoperatively to effectively address their expectations of treatment outcomes.

Abstract
OBJECTIVE The purpose of this study was to compare histologic underestimations at stereotactic 11- and 9-gauge vacuum-assisted breast biopsy. MATERIALS AND METHODS The reports of 1,223 consecutive stereotactic vacuum-assisted breast biopsies were retrospectively reviewed. An 11-gauge device was used to perform 828 and a 9-gauge device to perform 395 biopsies. The pathologic results were reviewed for all cases. Biopsy results of atypical ductal hyperplasia and ductal carcinoma in situ were compared with the pathologic results after surgical excision. Underestimation was defined as the need to upgrade atypical ductal hyperplasia to ductal carcinoma in situ or invasive carcinoma at surgery and to upgrade ductal carcinoma in situ to invasive carcinoma. Statistical significance was determined with the chi-square test and 95% CI. RESULTS In the 11-gauge group, 12 (26%) of 46 cases of atypical ductal hyperplasia were upgraded to ductal carcinoma in situ and one (2%) of the cases to invasive carcinoma. In the 9-gauge group, six (22%) of 27 cases of atypical ductal hyperplasia were upgraded to ductal carcinoma in situ and two (7%) of the cases to invasive carcinoma. In the 11-gauge group, 35 (28.7%) of 122 cases of ductal carcinoma in situ were upgraded to invasive carcinoma. In the 9-gauge group, 10 (23%) of 44 cases of ductal carcinoma in situ were upgraded to invasive carcinoma. CONCLUSION There was no statistically significant difference between 11-gauge biopsy and 9-gauge biopsy in underestimation of atypical ductal hyperplasia and ductal carcinoma in situ.

Abstract
Needle core biopsy (NCB), as part of triple assessment for preoperative evaluation and diagnosis of breast cancer, is now considered as an established, highly accurate method for diagnosing breast cancer that has replaced either fine needle aspiration cytology or excisional biopsy as the initial diagnostic biopsy procedures in many institutions. In addition to its primary role in establishing an accurate histological diagnosis, NCB can potentially provide important additional pathological prognostic information which may be of direct clinical value in certain situations, such as patients being considered for preoperative (neoadjuvant) therapy. With this background in mind we briefly review the current role of NCB in breast cancer diagnosis and then concentrate this review on the usefulness and issues relating to use of this technique in providing accurate, reliable and clinically relevant preoperative prognostic and predictive information in patients with breast cancer.

Abstract
BACKGROUND Preoperative diagnosis of breast abnormalities is currently the standard of care. A population-based study to determine the use of percutaneous needle biopsy for breast diagnosis in Ontario was performed. METHODS A total of 17,068 women undergoing breast tissue sampling (percutaneous needle biopsy or surgical excision) for diagnosis between April 1, 2002, and December 31, 2002, and without a previous cancer diagnosis were identified. Univariate and multivariate analyses examined the association of age, residence in a particular local health integration network (LHIN), income quintile, urban or rural residence, primary care provider, any prior mammogram, and prior regular screening mammography, as well as whether the biopsy was initiated by a screening mammogram with different methods of tissue diagnosis. RESULTS A total of 10,459 women (61%) underwent percutaneous biopsy for diagnosis. A total of 10,131 women underwent surgery, of whom 6,637 received a benign diagnosis and 3,494 had cancer, for a benign-to-malignant ratio of 1.9:1. Women with cancer were slightly more likely to undergo percutaneous biopsy than women without (64.7% vs. 60.3%). There was variation among LHINs in the use of percutaneous biopsy (range, 24%-72%). Women with the highest incomes, urban residence, a primary care provider, or history of any prior mammography were more likely to receive percutaneous biopsy. On multivariate analysis, age 50 to 69 years, LHIN, urban residence, primary care provider, and screen-initiated evaluation were associated with percutaneous biopsy. CONCLUSIONS Variation in the use of percutaneous biopsy by factors unrelated to indications for biopsy indicate that strategies to identify and overcome barriers to its use are needed.

Abstract
PURPOSE To evaluate the impact of preoperative diagnosis in obtaining negative lumpectomy margins. MATERIALS AND METHODS Five hundred and thirty five patients who underwent breast conserving therapy for stage I/II cancer from 1971 to 1996 were included in this IRB-approved retrospective analysis. Three hundred and ninety five patients had a defined inked margin status after initial excision. The following factors were evaluated for correlation with margins at initial excision: age (< or >45), grade (3/1 or 2), family history (present/absent), histology (lobular/other), estrogen receptor (ER) status, presence of extensive intraductal carcinoma (EIC), presence of lymphovascular invasion (LVI), and biopsy type (excisional/preoperative). RESULTS Biopsy type (P < 0.0001), EIC (P = 0.002), ER status (P = 0.02), lobular histology (P = 0.02) and age (P = 0.02) were significantly correlated with initial margin status among the entire group. For patients who underwent preoperative diagnostic biopsy, 52% (35/67) had negative initial margins as compared to 29% (94/328) for excisional biopsy. Among patients who underwent preoperative biopsy, only lobular histology (P = 0.04) and LVI (P = 0.04) were related to initial margin status. The rate of re-excision was 34% for patients diagnosed preoperatively versus 61% with excisional biopsy (P < 0.0001). The percentage of patients with negative final margin status was similar with either core/needle or excisional biopsy (79 and 78%, respectively). CONCLUSIONS Preoperative diagnosis is the most significant predictor of initial margin status in patients undergoing breast conservation. Patients with lobular histology may require improved preoperative and/or intraoperative assessment to increase the rate of negative margins at initial excision.

Abstract
BACKGROUND Although much data support the National Quality Forum recommendation that breast cancers should be diagnosed by needle biopsy before surgical resection, the exclusion criteria for those that may not be suitable have yet to be defined. METHODS We reviewed all patients treated over the past 3 years at the Yale Breast Center to determine the percentage of patients not diagnosed by needle biopsy, and why. RESULTS Reasons for the 17% of 630 patients who were not diagnosed by needle biopsy were as follows: inability to cooperate (1%); small or superficial lesion less than 1 cm that technically was easier to excise in the office (4%); bloody discharge without clinical or mammographic mass (1%); lesion adjacent to implant (.5%); a mammographic lesion that was too posterior, too superficial, or too faint to be performed stereotactically (5%); or patient preference (5%). CONCLUSIONS Needle biopsy is the preferred method of diagnosis in most cases, but there are valid reasons why all breast cancers will not be diagnosed in this fashion.

Abstract
OBJECTIVE The objective of our study was to retrospectively review our experience regarding the value of sonography in identifying a nonpalpable mass within a surgically excised specimen and in assessing the surgical margins in cases of malignancy. MATERIALS AND METHODS One hundred four lumpectomies were performed in 99 consecutive patients with 131 nonpalpable breast lesions after sonographically guided needle localization. All 104 surgical specimens were scanned on sonography, and 86 specimen radiographs were obtained. Visualization of the lesion on sonography was compared with specimen radiographs and histologic findings. Sonographic margin status was classified as negative (shortest distance between tumor and specimen margin, > 0.2 cm) or positive (shortest distance between tumor and specimen margin, 0.2 cm) and was compared with pathology results. RESULTS Specimen sonography showed 95.4% (125/131) of the excised abnormalities; nonfatty background and a lesion size of greater than 0.5 cm contributed significantly to the success of specimen sonography. Four of six lesions missed on sonography were identified on specimen radiography. Among 81 malignant specimens, sonography identified 38 specimens with positive margins and 43 with negative margins. Pathologic examination revealed eight false-positive and 10 false-negative results (21% false-positive rate and 23.2% false-negative rate). CONCLUSION Specimen sonography is an effective procedure for identifying the presence of the lesion within the specimen; however, it is of limited value in cases of small hypoechoic lesions against a fatty background. Assessment of margins is limited by both false-positive and false-negative results.

Abstract
AIM To assess the impact of mammotome biopsy on preoperative diagnosis rate. METHODS A prospective study was undertaken to examine the referral patterns, radiological abnormalities, sensitivity, specificity and outcome of the first 150 patients undergoing mammotome biopsy at our institution. Most of the referrals were from the NHS Breast Screening Programme (85/100). RESULTS The commonest radiological abnormality was microcalcification (87%). The accuracy of this biopsy technique for the target lesion was over 99%. Post-biopsy, 11 patients needed to proceed to a diagnostic surgical biopsy (7%). Forty-two malignancies were identified at final histology; 41 were diagnosed preoperatively. The positive predictive of mammotome biopsy was 98% for the present study. The present results for mammotome biopsy with regard to predicting invasion were: sensitivity 71.4% (10/14); specificity 100% (0/0); positive predictive value 100% (10/10); and negative predictive value 87% (27/31). CONCLUSION Prone mammotome biopsy has proven to be highly accurate, considerably improving the preoperative diagnosis within our unit, and obviating the majority of diagnostic excision biopsies.

Abstract
The Breast Imaging Reporting And Data System (BI-RADS) categorization of mammograms is useful in estimating the risk of malignancy, thereby guiding management decisions. However, in Asian women, in whom breast density is increased, the sensitivity of mammography is correspondingly lower. We sought to determine the positive predictive value of BI-RADS categorization for malignancy in our Asian population and, hence, its value in helping us to choose between the various modalities for breast biopsy. We retrospectively reviewed all patients with occult breast lesions detected on mammography or ultrasound who underwent needle-localization open breast biopsy (NLOB) in our institution over a 6-year period. There were 470 biopsies in 427 patients; 16% of lesions were malignant. The positive predictive value of BI-RADS 4 and 5 lesions for cancer was 0.27 and 0.84, respectively. While most BI-RADS 5 mass lesions were invasive cancers, the majority of calcifications in this category were in situ carcinomas. We conclude that BI-RADS remains useful in aiding decision-making for biopsy in our Asian population. Based on positive predictive values, we recommend percutaneous breast biopsy for initial evaluation of lesions categorized as BI-RADS 4 or less. For BI-RADS 5 lesions with microcalcifications, open surgical biopsy as a diagnostic and therapeutic procedure may be more appropriate. In the case of a BI-RADS 5 lesion associated with a mass, initial percutaneous biopsy may be useful for diagnosis, followed by a planned single-stage surgical procedure as necessary.

Abstract
INTRODUCTION Breast core needle biopsy (CNB) allows evaluation of histological, prognostic, and predictive factors in invasive mammary carcinomas (IMC). We tested the CNB accuracy on typing and grading of invasive breast carcinomas. MATERIALS AND METHODS A histological review of 120 CNBs and their related surgical specimens was carried out in a double-blind fashion. Tumor type and grade were assigned according to the World Health Organization classification and the Nottingham grading system. RESULTS The sum of CNB fragment lengths varied from 4 mm to 38 mm (mean 16.7 mm), and tumor sample size varied from 1 mm to 26 mm (mean 11.1 mm). Histological type matched surgical specimen evaluation in 80 of 120 cases (66.6%). Of the cases, 17 (14.2%) were changed to a different prognostic category. Histological grade comparison was accurate in 56 of 95 cases (59.0%, kappa=0.35). Histological grade components (tubule formation, nuclear grade, and mitotic index) agreed, respectively, in 54.7%, 58.9%, and 62.1% (kappa index 0.30, 0.36, and 0.28). DISCUSSION Typing IMC on CNB can be routinely assessed based on good correlation with surgical specimens, especially considering prognostic categories for IMC. Grading IMC based on CNB is not as accurate, and its evaluation should be delayed until the surgical specimen examination. Tumor heterogeneity seems to be the most important factor for disagreement.

Abstract
We report our experience with excision of hooked-wire bracketed breast carcinomas in a community hospital setting. The mammographic and pathology reports from 36 nonpalpable or minimally palpable breast cancers were retrieved from a single surgical oncologist's office records and a number of factors that might influence a successful initial surgical excision were examined. The median lesion size was 1 cm. The radiographic abnormalities were microcalcifications only in 14 cases (39%), combined mass/density and microcalcifications in 9 cases (25%), and mass/density without microcalcifications in 13 cases (36%). The median number of bracketing wires placed was two. A prior fine-needle aspiration (FNA) or core biopsy was performed in 29 of the 36 cases (81%). Of these, 27 were positive for malignancy. The tumor was considered to be inadequately excised if it was present within 5 mm of any surgical margin; this outcome occurred in 21 of the 36 cases (58%). Fifteen cases (42%) had tumor involving either the margin or extending to within 1 mm of the margin. Inadequately excised lesions were more commonly seen with increasing tumor size, a radiographic appearance of microcalcifications without an associated mass, and a pathologic diagnosis of ductal carcinoma in situ (DCIS). An intraoperative consult led to taking additional marginal tissue in 23 cases and was successful in achieving final clear histologic margins in 8 of these (35%). Our experience suggests that there are at least two ways to optimize the adequacy of conservative excision of nonpalpable or difficult-to-palpate breast cancers using standard modalities presently available in most community hospitals. These are (a) having the pathologist and radiologist available for intraoperative consultation and (b) obtaining a tissue diagnosis of malignancy preoperatively. The use of bracketing wires to better delineate the margins of tissue to be excised may also be helpful, but this needs to be further evaluated in a randomized study.

Abstract
This paper describes the B-mode, colour and spectral Doppler appearances of breast pseudoaneurysm - a rare vascular complication of ultrasound-guided needle core biopsy. Previously reported cases of spontaneous and iatrogenic pseudoaneurysm of the breast are reviewed. The significance of this potentially serious complication is discussed with reference to the increasing use of imaging and image guided techniques in the diagnosis of breast disease.

Abstract
INTRODUCTION Due to screening mammography, more nonpalpable mammographic lesions warrant histological evaluation. Stereotactic large-core needle biopsy (SLCNB) has been shown to be as effective in diagnosing these lesions as diagnostic surgical excision, and has become the preferred diagnostic procedure for most mammographic lesions. Since radiologically malignant BI-RADS 5 lesions are almost always carcinoma, some centers advocate prompt diagnostic surgical excision for these lesions instead of SLCNB. For some patients this diagnostic surgical intervention may serve as definitive treatment. We set out to find a subgroup of mammographic BI-RADS 5 lesions for which surgical biopsy might be preferable. METHODS Of 1644 consecutive nonpalpable lesions referred for SLCNB between April 1997 and May 2002, 238 were classified as BI-RADS 5. We assessed the number of carcinomas and the surgical interventions performed. Outcomes were compared between various types of mammographic lesions: density with calcifications, density without calcifications, and calcifications only. Different theoretical strategies for diagnostic work-up of BI-RADS 5 lesions were explored. RESULTS Carcinoma was found in 229/238 lesions (96%). Most mammographic densities were invasive cancer (97%), while calcifications only showed the highest risk for DCIS (51%). In our study (current practice) all lesions were scheduled to first undergo SLCNB. A scenario was proposed where all lesions with only a density would be scheduled directly for sentinel node biopsy (SNB) and tumour excision (n = 154; 65%), while other lesions would still be scheduled for SLCNB. When we compared this scenario to current practice, four out of 238 patients (< 2%) would be 'overtreated' with SNB. CONCLUSIONS Our findings confirm a high predictive value of malignancy for BI-RADS 5 lesions (96%). Surgical excision is therefore imperative for all BI-RADS 5 lesions, irrespective of SLCNB results. For BI-RADS 5 lesions presenting as mammographic densities only, we propose to consider surgical excision with SNB to be the first diagnostic and therapeutic procedure. SLCNB is preferred in all other cases.

Abstract
PURPOSE To describe the clinical and economic consequences of image-guided core biopsy versus surgical excisional biopsy of mammographically identified breast lesions. PATIENTS AND METHODS Clinical and economic data were collected for 1121 patients undergoing core biopsies and 501 patients undergoing surgical biopsies between 1996 and 1998. Lesions were classified according to mammographic degree of suspicion and type of radiographic abnormality. Costs were measured from the societal perspective. A decision analytic model was constructed, with probabilistic sensitivity analysis. RESULTS Lesions diagnosed via core versus surgical biopsy were less likely to be masses (39% v 55%), less likely to be classified as high cancer suspicion (17% v 26%), and less likely to be treated with a single procedure (74% v 81%; P <.001 for each). Cancers diagnosed by a surgical biopsy were less likely to have had a single operative procedure (33% v 84%) and were associated with higher total costs whether mastectomy (US dollars 2775 v US dollars 1849) or lumpectomy (US dollars 2112 v US dollars 1365) was used. Sensitivity analysis showed core biopsy optimal in 95.4% of trials. Core biopsy was favored for low-suspicion lesions, calcifications, and masses, and overall for patients who underwent lumpectomy alone. CONCLUSION Image-guided core biopsy can be cost-saving compared with surgical biopsy, particularly when the mammographic abnormality is classified as low suspicion or consists of calcifications or masses. Moving to a policy in which core biopsy is the preferred approach in these settings has the potential to result in significant cost savings.

Abstract
OBJECTIVE This study was undertaken to compare patient perceptions of 2 common image-guided breast biopsy procedures on 3 main outcomes: decision making about which procedure to undergo, its convenience, and its side effects. METHODS Women who had either an excisional or ultrasound-guided core needle breast biopsy in 1997 for a screen-detected lesion had telephone interviews 1 to 3 months after the biopsy. Bivariate associations were tested by using chi(2) and t test statistics. Mulitvariate analyses were used to control for effects of demographic characteristics. RESULTS Most women (66%) could not remember being offered a choice of procedures, and of those who did have a choice, a higher proportion had an excisional biopsy. Only 2% reported being told the cost of the biopsy procedure. Women who had an excisional biopsy compared with those who had undergone a core needle biopsy reported statistically more hours and days off from work and reported more side effects 1 to 3 days after the biopsy (P<.05). Associations between side effects and type of biopsy procedure were unchanged when adjustment was made for demographic characteristics. CONCLUSION Women who had the ultrasound-guided needle biopsy reported significantly fewer side effects and needed less time off from work. When a suspicious lesion is noticed on a screening mammogram, it is important that women and their physicians discuss the benefits and risks of the various biopsy procedures before deciding how to proceed, allowing for informed choice.

Abstract
This paper reports a descriptive study of the costs and quality of life (QoL) outcome of treatments for early stage breast cancer in a cohort of Australian women, one year after initial surgical treatment. Mastectomy without breast reconstruction is compared to breast conserving surgery and radiotherapy (breast conservation). Of the 397 women eligible for the study, costing data were collected for 81% and quality of life data for 73%. The cost differences between treatment groups were mainly accounted for by adjuvant therapies, the more expensive being radiotherapy. When compared to women treated by mastectomy, those treated by breast conservation reported better body image but worse physical function. The negative impact of breast cancer and its treatment was greater for younger women, across a number of dimensions of quality of life (regardless of treatment type). While this study shows that breast conservation is more expensive than mastectomy, the QoL results reinforce the importance of patient participation in treatment decisions.

Abstract
BACKGROUND Vacuum-assisted breast biopsy (VAB) can replace surgical biopsy for the diagnosis of breast carcinoma. The authors evaluated the accuracy and clinical utility of VAB in a multicenter setting using a strict quality assurance protocol. METHODS In the current study, VABs were performed successfully for 2874 patients at 5 sites. Benign lesions were verified by follow-up. Surgery was recommended for malignant and borderline lesions. VAB was performed on patients with lesions rated as highly suspicious (6%), intermediate to suspicious (85%), or probably benign (9%). Fifty-eight percent of the lesions were < 10 mm and 70% had microcalcifications. RESULTS The authors identified 7% of patients with invasive carcinomas, 15% with ductal carcinomas in situ (DCIS), 5% with atypical ductal hyperplasias (ADH), and 0.6% with lobular carcinomas in situ. The results of the VAB necessitated an upgrade of 24% of patients with ADH to DCIS or DCIS and invasive carcinoma. Twelve percent of patients with DCIS proved to have invasive carcinoma. Seventy-three percent of the patients had benign lesions. Only 1 false-negative result was encountered (negative predictive value, 99.95%). Minor side effects were reported to occur in 1.4% of patients and 0.1% of patients required a subsequent intervention. Scarring relevant for mammography was rare among patients (i.e., 0.3% of patients had relevant scarring). CONCLUSIONS Quality-assured VAB was found to be highly reliable. VAB effectively identified patients with benign lesions and assisted therapeutic decisions. Most important, only a single case of malignancy was missed. A close interdisciplinary approach assured optimal results.

Abstract
BACKGROUND Screen-detected ductal carcinoma in situ (DCIS) usually presents as clinically impalpable microcalcification. Although core biopsy is well established as a diagnostic modality for invasive breast cancers, few reports address its impact on the management of screen-detected DCIS. We examined the sensitivity of core biopsy in diagnosing screen-detected DCIS, as well as its role in facilitating one-step surgery in the community, especially a breast-conserving approach. METHODS Through the Monash BreastScreen database, we reviewed the management of 148 patients diagnosed with pure DCIS over a 4-year period. Particular attention was paid to the sensitivity and surgical margin status of 63 patients who underwent initial assessment with core biopsy, compared to patients who underwent excisional biopsy or fine needle aspiration cytology (FNAC). RESULTS Core specimens in 63 patients yielded positive histology in 57 (90%), allowing for breast-conserving surgery in 45 and mastectomy in 12. Negative margins were obtained in 73% of those treated by breast-conserving surgery, compared to 51% negative margins among those who underwent excisional biopsy initially. Overall, 45 of 57 patients with a positive core biopsy histology (79%) underwent one-step surgery. Those assessed by FNAC had a 48% incidence of non-diagnostic/benign cytology. CONCLUSIONS Core biopsy facilitates one-step surgery for screen-detected DCIS, and potentially reduces the number of surgical procedures. Stereotactic core biopsy for suspicious microcalcifications should replace hookwire-guided excisional biopsy and FNAC as the diagnostic modality of choice.

Abstract
BACKGROUND Wire localization (WL) is the current standard for surgical diagnosis of nonpalpable breast lesions. Many disadvantages inherent to WL are solved with radioactive seed localization (RSL). This trial investigated the ability of RSL to reduce the need for specimen radiographs and operating room delays associated with WL. METHODS A total of 134 women were entered onto an institutional review board-approved study. RSL was performed by placing a titanium seed containing.29 to 20 mCi of iodine-125 to within 1 cm of the suggestive breast lesion. The surgeon used a handheld gamma detector to locate and excise the iodine-125 seed and the lesion. RESULTS Specimen radiographs were eliminated in 98 (79%) of 124 patients. Surgical seed retrieval was 100% in 124 patients. No seed migration occurred after correct radiographical placement. A total of 26 (21%) of 124 patients required a specimen radiograph; 22 (85%) of these 26 were performed for microcalcifications. CONCLUSIONS After surgical removal, RSL can eliminate specimen radiographs when the radiologist accurately places the seed and the pathologist grossly identifies the lesion. If small microcalcifications are noted before surgery, then specimen radiographs may be necessary. RSL reduced requirements for specimen radiographs, decreased OR time, improved incision placement, and improved resections to clear margins.

Abstract
Until recently little advance in the diagnosis and excision of breast cancer has been made since the inception of needle localization breast biopsy (NLBB). Stereotactic core needle breast biopsy (SCNBB) can avoid most NLBB especially for calcifications. However, when open biopsy is necessary NLBB has been the standard of care. As many as 50 per cent of nonpalpable lesions can be seen by ultrasound (US) to avoid the unpleasantness and complications associated with NLBB. Further SCNBB leaves a blood-filled cavity that can be easily seen by US. Intraoperative US can be used to direct the excision while improving margin negativity. MRI has improved sensitivity in detecting suspicious breast lesions and techniques such as hematoma-directed US-guided breast biopsy can facilitate excision of such masses. Clearly new technologies have improved the ability to diagnosis and excise breast cancer. The onus on the surgeon is to incorporate them into standard practice to improve outcomes.

Abstract
AIMS With the increasing use of screening mammography, more and more non-palpable lesions are found. As less invasive techniques like core needle biopsy are introduced, we evaluated our experience with the well-known standard procedure of surgical excision after wire localization. METHODS We retrospectively evaluated the results of 479 wire localizations for non-palpable breast lesions between 1992 and 1999 in 465 patients. Feasibility and reliability of the procedure and the incidence of complications are reported. RESULTS The mean age of these patients was 57 years (range 22-81 years). The mammographic finding with the highest rate of malignancy was density combined with architectural distortion (72%). The removal of the lesion was radiologically confirmed in 93%; if the lesion appeared to be not removed, after 3 months mammography was repeated, in 14 patients a second localization procedure was done and in 10 patients still a malignancy was found. In 79%, the excision after initial fine-wire localization was irradical. Twenty-five patients developed a haematoma and five patients had a wound infection. The overall malignancy rate was 50%. With a mean follow-up of 18 months in 11 patients with a diagnosis of benign disease after an adequate procedure, still a malignancy was found at the original excision site. CONCLUSION In selected cases, especially as a part of the therapeutic procedure in breast-conserving therapy, there will remain a place for wire localization and excision biopsy. However, we have to reconsider its place as a diagnostic procedure as the results of less invasive procedures are promising.

Abstract
BACKGROUND The objective was to compare the safety and effectiveness of a new localization device to traditional flexible wires. Safety variables included blood loss, procedure time, pain and complications. Effectiveness variables included placement accuracy, lesion retrieval, histological diagnosis, procedural enhancements, and margin status. METHODS Twelve sites enrolled 120 patients between June 2000 and June 2001, with 58 randomized to treatment and 62 to control. RESULTS The two groups were equivalent in device placement accuracy, lesion retrieval, histological diagnosis, blood loss, pain, and complications. There was a significant difference favoring the treatment group for procedural enhancements, (ie, use as a palpable guide and retractor) and operating time. There were significantly fewer positive margins in the treatment group. CONCLUSIONS This multicenter trial demonstrated equivalent safety and improved effectiveness for the treatment group. The new device demonstrated greater surgeon utility, reduced operative time, and fewer positive margins than the current wires.

Abstract
BACKGROUND Needle localization breast biopsy (NLBB) is the standard for removal of breast lesions after vacuum assisted core biopsy (VACB). Disadvantages include a miss rate of 0% to 22%, a positive margin rate of approximately 50%, and vasovagal reactions (approximately 20%). We hypothesized that clip migration after VACB is clinically significant and may contribute to the positive margin rates seen after NLBB. METHODS We performed a retrospective review of postbiopsy films in patients who had undergone VACB with stereotactic clip placement for abnormal mammograms. We measured the distance between the clip and the biopsy site in standard two view mammograms. The location of the biopsy air pocket was confirmed using the prebiopsy calcification site. The Pythagorean Theorem was used to calculate the distance the clip moved within the breast. Pathology reports on NLBB or intraoperative hematoma-directed ultrasound-guided breast biopsy (HUG, which localizes by US the VACB site) were reviewed to assess margin status. RESULTS In all, 165 postbiopsy mammograms on patients who had VACB with clip placement were reviewed. In 93 evaluable cases, the mean distance the clip moved was 13.5 mm +/- 1.6 mm, SEM (95% CI = 10.3 mm to 16.7 mm). Range of migration was 0 to 78.3 mm. The median was 9.5 mm. In 21.5% of patients the clip was more than 20 mm from the targeted site. Migration of the clip did not change with the age of the patient, the size of the breast or location within the breast. In the subgroup of patients with cancer, margin positivity (including those with close margins) after NLBB was 60% versus 0% in the HUG group. CONCLUSIONS Significant clip migration after VACB may contribute to the high positive margin status of standard NLBBs. Surgeons cannot rely on needle localization of the clip alone and must be cognizant of potential clip migration. HUG as an alternative biopsy technique after VACB eliminates operator dependency on clip location and may have superior results in margin status.
