Cancers (Basel) 2024; 16:1813. [PMID: 38791892 PMCID: PMC11119905 DOI: 10.3390/cancers16101813] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Revised: 04/30/2024] [Accepted: 05/02/2024] [Indexed: 05/26/2024] Open
Abstract
This study aims to evaluate several defined specimen parameters that would allow to determine the surgical accuracy of breast-conserving surgeries (BCS) in a representative population of patients. These specimen parameters could be used to compare surgical accuracy when using novel technologies for intra-operative BCS guidance in the future. Different specimen parameters were determined among 100 BCS patients, including the ratio of specimen volume to tumor volume (resection ratio) with different optimal margin widths (0 mm, 1 mm, 2 mm, and 10 mm). Furthermore, the tumor eccentricity [maximum tumor-margin distance - minimum tumor-margin distance] and the relative tumor eccentricity [tumor eccentricity ÷ pathological tumor diameter] were determined. Different patient subgroups were compared using Wilcoxon rank sum tests. When using a surgical margin width of 0 mm, 1 mm, 2 mm, and 10 mm, on average, 19.16 (IQR 44.36), 9.94 (IQR 18.09), 6.06 (IQR 9.69) and 1.35 (IQR 1.78) times the ideal resection volume was excised, respectively. The median tumor eccentricity among the entire patient population was 11.29 mm (SD = 3.99) and the median relative tumor eccentricity was 0.66 (SD = 2.22). Resection ratios based on different optimal margin widths (0 mm, 1 mm, 2 mm, and 10 mm) and the (relative) tumor eccentricity could be valuable outcome measures to evaluate the surgical accuracy of novel technologies for intra-operative BCS guidance.

World J Surg Oncol 2024; 22:72. [PMID: 38419107 PMCID: PMC10902948 DOI: 10.1186/s12957-024-03354-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Accepted: 02/24/2024] [Indexed: 03/02/2024] Open
Abstract
BACKGROUND To explore the capability and clinical significance of chest thin-section computed tomography (CT) for localization of mammographically detected clustered microcalcifications. METHODS A total of 69 patients with 71 mammographically detected clustered microcalcifications received surgical biopsy under the guidance of mammography (MG), CT was used to localize calcifications combined with MG if calcifications can be seen on CT. Intraoperative mammography of the specimens were performed in all cases for identification of the resected microcalcifications. The clinical, imaging and pathological information of these patients were analyzed. RESULTS A total of 42 (59.15%) cases of calcifications were localized by CT + MG, 29 (40.85%) cases were guided only by the mammography. All suspicious calcifications on the mammography were successfully removed. Pathological results showed 42 cases were cancer, 23 cases were benign, and 6 cases were atypical hyperplasia. The mean age in the CT + MG group was older than that of the MG group (54.12 vs. 49.27 years; P = 0.014). The maximum diameter of clusters of microcalcifications on mammography in the CT + MG group was larger than that of the MG group [(cranio-caudal view, 1.52 vs. 0.61 mm, P = 0.000; mediolateral oblique (MLO) view, 1.53 vs. 0.62 mm, P = 0.000)]. The gray value ratio (calcified area / paraglandular; MLO, P = 0.004) and the gray value difference (calcified area - paraglandular; MLO, P = 0.005) in the CT + MG group was higher than that of the MG group. Multivariate analysis showed that the max diameter of clusters of microcalcifications (MLO view) was a significant predictive factor of localization by CT in total patients (P = 0.001). CONCLUSIONS About half of the mammographically detected clustered microcalcifications could be localized by thin-section CT. Maximum diameter of clusters of microcalcifications (MLO view) was a predictor of visibility of calcifications by CT. Chest thin-section CT may be useful for localization of calcifications in some patients, especially for calcifications that are only visible in one view on the mammography.

Abstract
The validation of newly developed optical tissue-sensing techniques for tumor detection during cancer surgery requires an accurate correlation with the histological results. Additionally, such an accurate correlation facilitates precise data labeling for developing high-performance machine learning tissue-classification models. In this paper, a newly developed Point Projection Mapping system will be introduced, which allows non-destructive tracking of the measurement locations on tissue specimens. Additionally, a framework for accurate registration, validation, and labeling with the histopathology results is proposed and validated on a case study. The proposed framework provides a more-robust and accurate method for the tracking and validation of optical tissue-sensing techniques, which saves time and resources compared to the available conventional techniques.

Abstract
During breast-conserving surgeries, it remains challenging to accomplish adequate surgical margins. We investigated different numbers of fibers for fiber-optic diffuse reflectance spectroscopy to differentiate tumorous breast tissue from healthy tissue ex vivo up to 2 mm from the margin. Using a machine-learning classification model, the optimal performance was obtained using at least three emitting fibers (Matthew's correlation coefficient (MCC) of 0.73), which was significantly higher compared to the performance of using a single-emitting fiber (MCC of 0.48). The percentage of correctly classified tumor locations varied from 75% to 100% depending on the tumor percentage, the tumor-margin distance and the number of fibers.

Abstract
Radio-frequency (RF) ablation is a reliable technique for the treatment of deep-seated malignant tumors, including breast carcinoma, using high ablative temperatures. The paper aims at a comparative analysis of the specific absorption rate and temperature distribution during RF ablation with regard to different female breast tumors. In the study, four tumor models equivalent to an irregular tumor were considered, i.e., an equivalent sphere and ellipsoid with the same surfaces and volumes as the irregular tumor and an equivalent sphere and ellipsoid inscribed in the irregular tumor. An RF applicator with a specific voltage, operating at 100 kHz inserted into the anatomically correct female breast, was applied as a source of electromagnetically induced heat. A conjugated Laplace equation with the modified Pennes equation was used to obtain the appropriate temperature gradient in the treated area. The levels of power dissipation in terms of the specific absorption rate (SAR) inside the naturalistically shaped tumor, together with the temperature profiles of the four simplified tumor models equivalent to the irregular one, were determined. It was suggested that the equivalent tumor models might successfully replace a real, irregularly shaped tumor, and the presented numeric methodology may play an important role in the complex therapeutic RF ablation process of irregularly shaped female breast tumors.

Abstract
OBJECTIVE During breast conserving surgery (BCS), magnetic resonance (MR) images aligned to accurately display intraoperative lesion locations can offer improved understanding of tumor extent and position relative to breast anatomy. Unfortunately, even under consistent supine conditions, soft tissue deformation compromises image-to-physical alignment and results in positional errors. METHODS A finite element inverse modeling technique has been developed to nonrigidly register preoperative supine MR imaging data to the surgical scene for improved localization accuracy during surgery. Registration is driven using sparse data compatible with acquisition during BCS, including corresponding surface fiducials, sparse chest wall contours, and the intra-fiducial skin surface. Deformation predictions were evaluated at surface fiducial locations and subsurface tissue features that were expertly identified and tracked. Among n = 7 different human subjects, an average of 22 ± 3 distributed subsurface targets were analyzed in each breast volume. RESULTS The average target registration error (TRE) decreased significantly when comparing rigid registration to this nonrigid approach (10.4 ± 2.3 mm vs 6.3 ± 1.4 mm TRE, respectively). When including a single subsurface feature as additional input data, the TRE significantly improved further (4.2 ± 1.0 mm TRE), and in a region of interest within 15 mm of a mock biopsy clip TRE was 3.9 ± 0.9 mm. CONCLUSION These results demonstrate accurate breast deformation estimates based on sparse-data-driven model predictions. SIGNIFICANCE The data suggest that a computational imaging approach can account for image-to-surgery shape changes to enhance surgical guidance during BCS.

Abstract
Wire-guided localization (WGL) is the most frequently used localization technique in non-palpable breast cancer (BC). However, low negative margin rates, patient discomfort, and the possibility of wire dislocation have been discussed as potential disadvantages, and re-operation due to positive margins may increase relapse risk. Intraoperative ultrasound (IOUS)-guided excision allows direct visualization of the lesion and the resection volume and reduces positive margins in palpable and non-palpable tumors. We performed a systematic review on IOUS in breast cancer and 2 meta-analyses of randomized clinical trials (RCTs). In non-palpable BC, 3 RCTs have shown higher negative margin rates in the IOUS arm compared to WGL. Meta-analysis confirmed a significant difference between IOUS and WGL in terms of positive margins favoring IOUS (risk ratio 4.34, p < 0.0001, I2 = 0%). 41 cohort studies including 3291 patients were identified, of which most reported higher negative margin and lower re-operation rates if IOUS was used. In palpable BC, IOUS was compared to palpation-guided excision in 3 RCTs. Meta-analysis showed significantly higher rates of positive margins in the palpation arm (risk ratio 2.84, p = 0.0047, I2 = 0%). In 13 cohort studies including 942 patients with palpable BC, negative margin rates were higher if IOUS was used, and tissue volumes were higher in palpation-guided cohorts in most studies. IOUS is a safe noninvasive technique for the localization of sonographically visible tumors that significantly improves margin rates in palpable and non-palpable BC. Surgeons should be encouraged to acquire ultrasound skills and participate in breast ultrasound training.

Abstract
Background Although the incidence of positive resection margins in breast-conserving surgery has decreased, both incomplete resection and unnecessary large resections still occur. This is especially the case in the surgical treatment of ductal carcinoma in situ (DCIS). Diffuse reflectance spectroscopy (DRS), an optical technology based on light tissue interactions, can potentially characterize tissue during surgery thereby guiding the surgeon intraoperatively. DRS has shown to be able to discriminate pure healthy breast tissue from pure invasive carcinoma (IC) but limited research has been done on (1) the actual optical characteristics of DCIS and (2) the ability of DRS to characterize measurements that are a mixture of tissue types. Methods In this study, DRS spectra were acquired from 107 breast specimens from 107 patients with proven IC and/or DCIS (1488 measurement locations). With a generalized estimating equation model, the differences between the DRS spectra of locations with DCIS and IC and only healthy tissue were compared to see if there were significant differences between these spectra. Subsequently, different classification models were developed to be able to predict if the DRS spectrum of a measurement location represented a measurement location with “healthy” or “malignant” tissue. In the development and testing of the models, different definitions for “healthy” and “malignant” were used. This allowed varying the level of homogeneity in the train and test data. Results It was found that the optical characteristics of IC and DCIS were similar. Regarding the classification of tissue with a mixture of tissue types, it was found that using mixed measurement locations in the development of the classification models did not tremendously improve the accuracy of the classification of other measurement locations with a mixture of tissue types. The evaluated classification models were able to classify measurement locations with > 5% malignant cells with a Matthews correlation coefficient of 0.41 or 0.40. Some models showed better sensitivity whereas others had better specificity. Conclusion The results suggest that DRS has the potential to detect malignant tissue, including DCIS, in healthy breast tissue and could thus be helpful for surgical guidance.

Abstract
Objective Positive margins remain a significant psychological and economic burden after breast conserving surgery. The aim of this study was to test the hypothesis that advanced oncoplastic techniques as well as intraoperative integrative imaging with intraoperative ultrasound and mobile digital specimen radiography decreases positive margin rate in breast conserving surgery. Methods A single-institution retrospective review of a prospectively collected database was performed. Patients with breast neoplasms who underwent lumpectomy with or without using intraoperative integrative imaging approaches and oncoplastic techniques were included. The primary outcome was positive margin rate for each technique. Results A total of 392 patients were included in the study. The median age of the cohort was 59 years. Overall positive margin rate was 15%. Ductal carcinoma in situ (DCIS) histology and larger tumor size were associated with higher positive margin rate. Intraoperative integrative imaging significantly decreased positive margin rate (9% vs. 18%, p=0.018). Oncoplastic techniques also decreased positive margin rate from 16% to 12%, however this was not significant. Conclusion Positive margin rate was significantly lower when intraoperative integrative imaging was used. Oncoplastic techniques also decreased positive margin rate in a selected group of patients with large tumor size. We suggest incorporating these techniques in all breast conserving surgery cases.

Am J Surg 2020; 220:1410-1416. [PMID: 32958157 DOI: 10.1016/j.amjsurg.2020.09.008] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Revised: 06/11/2020] [Accepted: 09/03/2020] [Indexed: 01/19/2023]
Abstract
BACKGROUND The oncologic goal of margin-negative breast conservation requires adequate localization of tumor. Intraoperative ultrasound remains most feasible but under-utilized method to localize the tumor and assess margins. METHODS A prospectively maintained breast cancer database over a decade was queried for margin status in breast cancer patients undergoing breast conservation. Techniques of tumor localization, margin re-excision and closest margins were analyzed. Rate of conversion to mastectomy was determined. RESULTS Of the 945 breast cancer patients treated at a university-based Breast Center of Excellence between January 1, 2009 and December 31, 2018, 149(15.8%) had ductal carcinoma in situ; 712(75.3%) had invasive ductal carcinoma, and 63(6.7%) had invasive lobular carcinoma. Clinical stage distribution was: T1 = 372(39.4%); T2 = 257(27.2%); T3 = 87(9.2%). Five hundred and eighty three (61.7%) patients underwent breast conservation. The median (25th -75th centile) closest margin was 6(2.5, 10.0) mm. Thirty five (6.0%) patients underwent margin re-excision, of which 9(25%) were converted to mastectomy. Tumor localization was achieved with ultrasound in 521(89.4%) patients and with wire localization in 62(10.6%) patients. The median (25th-75th centile) closest margin with wire localization was 5.0(2.0, 8.5) mm versus 5.0 (2.0, 8.0) mm with ultrasound guidance [p = 0.6635]. The re-excision rate with wire localization was 14.5% versus 4.9% with ultrasound guidance [p = 0.0073]. The unadjusted Odds Ratio (95% CI) for margin revision in wire localized group compared with ultrasound was 3.2 (7.14, 1.42) [p = 0.0045]; multivariate adjusted OR (95%) was 4(9.09, 1.7) [p = 0.0013]. CONCLUSIONS Ultrasound guidance for localization of breast cancer remains the most effective option for margin negative breast conservation.

Abstract
BACKGROUND The re-excision rates after breast-conserving surgery (BCS) are significantly varied, with surgeon case volume as one influential factor. Surgeons with higher case volumes have been shown to have lower reoperation rates. This study attempted to determine whether this may be attributable to excessive breast tissue removal during initial BCS. METHODS A retrospective study analyzed referrals to the authors' cancer center during 3 years. Patients undergoing initial BCS for ductal carcinoma in situ or T1-T3 breast cancers were included. Patient age, tumor factors, surgeon case volume, and the calculated resection ratio (CRR) were analyzed. The total resection volume was divided by the optimal resection volume to produce the CRR, which reflected the magnitude of excess tissue resected during initial BCS. Comparison of the mean CRR between surgeon case-volume categories was performed with a repeated measures analysis of variance. A multivariate regression model assessed the effects of the CRR and surgeon case volume on re-excision rates. RESULTS Larger tumor size, lobular histology, and lower CRR were associated with increased re-excision rates. The CRR was similar for each surgeon case-volume group. Surgeon case volume was not independently associated with re-excision rates, but surgeons with very high case volumes had lower odds of re-excision than surgeons with intermediate case volumes (odds ratio 0.44; 95% confidence interval 0.21-0.91). CONCLUSIONS When control was used for the CRR, apparent differences in re-excision rates between surgeon case-volume groups were observed, suggesting that surgeons with higher case volumes may be more accurate when performing BCS.

Abstract
BACKGROUND AND AIM Traditionally lumpectomy as a part of breast-conserving surgery (BCS) is performed by palpation-guided method leading to positive margins and large excision volumes. There is no evidence suggesting that wide margin excisions decrease intra-breast tumour recurrence. Various perioperative techniques are used for margin assessment. We aimed to compare three commonly used techniques, i.e., ultrasound-guided surgery, palpation-guided surgery and cavity shaving for attaining negative margins and estimating the extent of healthy breast tissue resection. METHOD A prospective comparative study was performed on 90 patients who underwent breast conservation surgery for early breast cancer between August 2018 and June 2019. Tumour excision with a minimum of 1 cm margin was done either using ultrasound, palpation or cavity shaving. Histopathological evaluation was done to assess the margin status and excess amount of resected normal breast tissue. Calculated resection ratio (CRR) defining the excess amount of the resected breast tissue was achieved by dividing the total resection volume (TRV) by optimal resection volume (ORV). The time taken for excision was also recorded. RESULTS Histopathology of all 90 patients (30 in each group) revealed a negative resection margin in 93.3% of 30 patients in palpation-guided surgery group and 100% in both ultrasound-guided surgery and cavity shaving groups. Two patients (6.7%) from the cavity shaving group had positive margins on initial lumpectomy but shave margins were negative. TRV was significantly less in the ultrasound-guided surgery group compared to the palpation-guided surgery group and cavity shaving group (76.9 cm3, 94.7 cm3 and 126.3 cm3 respectively; p < 0.0051). CRR was 1.2 in ultrasound group compared to 1.9 in palpation group and 2.1 in cavity shave group which was also statistically significant (p < 0.0001).Excision time was significantly less (p < 0.001) in palpation-guided surgery group (13.8 min) compared to cavity shaving group (15.1 min) and ultrasound-guided group (19.4 min). CONCLUSION Ultrasound-guided surgery is more accurate in attaining negative margins with the removal of least amount of healthy breast tissue compared to palpation-guided surgery and cavity shaving.

Abstract
For clinically low-volume breast cancer patients subjected to BCS, there is a concern regarding achieving microscopically negative margins and avoiding inadvertent resection of excessive volume of breast tissue. In this study, we utilized intraoperative ultrasound to guide resection in patients subjected to BCS. This was compared with palpation-guided resection. A total of 80 patients of invasive breast carcinoma (T1-2, N0-1, M0) (39 patients in USG-guided BCS (group A) and 41 patients in palpation-guided BCS (group B)) were enrolled. In group A, intraoperative localization was performed using a multifrequency 10-MHz linear array ultrasound probe and tumors were excised under USG guidance. In group B, tumor excision was guided by the palpation skills of the surgeon with the aim of achieving grossly negative margin circumferentially. Specimen volume was measured using water displacement technique. One out of 39 patients (2.56%) in group A and 5 out of 41(12.19%) in group B had positive margin in histopathology report. Mean of specimen volume in groups A and B was 42.67 and 57.97 ml respectively (P = 0.011). Mean of excess volume removed in study group was 4.19 ml and in control group, it was 24.11 ml (P = < 0.01). Mean of calculated resection ratio in study group was 1.1 and in control group was 1.73 (P = 0.01). Use of intraoperative ultrasound during BCS may help in improving margin clearance, reducing additional procedures, and preserving the normal breast parenchyma. The safety, ease, and effectivity of this technique may result in its wider application in future.

Radio-guided and clip-guided preoperative localization for malignant microcalcifications offer similar performances in breast-conserving surgery. Breast J 2019; 25:865-873. [PMID: 31187568 DOI: 10.1111/tbj.13354] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2018] [Revised: 01/07/2019] [Accepted: 01/09/2019] [Indexed: 11/30/2022]
Abstract
Obtaining a tailored breast resection is challenging in microcalcifications detected on screening mammography, and an accurate localization is required. The aim of this study was to compare the efficacy of radio-guided localization (ROLL) versus ultrasound localization of a titanium clip with collagen (TCC) in terms of clear margins, re-intervention rates, excess of resected breast tissue, and operative times in pure malignant microcalcifications detected on screening mammography. Two hundred and twenty-one consecutive patients with malignant microcalcifications detected on screening mammography from a tertiary breast unit were reviewed: 177 patients were localized by TCC and 44 patients by stereotactic ROLL. A propensity score-matched analysis was performed, followed by a logistic regression model, to avoid selection bias. Adequacy of resection was expressed as the calculated resection ratio considering lesion size. No differences were found in clear margins with ROLL versus TCC (77.3% vs 81.8%, adjusted OR 2, P = 0.27). Re-operation rates were similar, being 11.3% with ROLL and 7.4% with TCC (P = 0.627). Mean resection volume was 46.2 cm3 with ROLL versus 54.2 cm3 with TCC (P = 0.222). Adjusted mean calculated resection ratio was 1.8 with ROLL and 2.1 with TCC (P = 0.38). Surgery time was longer with TCC compared to ROLL (69.6 vs 52.7 minutes, P < 0.0001). ROLL and TCC are equally effective to excise malignant microcalcifications with clear margins, providing similar re-intervention rates and resection volumes.

Abstract
PURPOSE To evaluate the three-dimensional visualization technique (3DVT) in endoscopic breast-conserving surgery (EBCS) and pedicled omentum for immediate breast reconstruction. METHODS Clinical data of 256-slice multi-detector CT scanning from 52 patients (group A) were introduced into self-developed Medical Imaging 3D Visualization Systems (MI-3DVS) for individualized segmentation, 3D reconstruction and volume calculation. The surgical process was designed according to the 3D model. Next, the EBCS and pedicled omentum breast reconstruction were performed according to the preoperative design. Finally, the operating time, blood loss, length of postoperative hospital stay, complications and cosmetic outcomes in group A were compared to 44 patients in group B, who underwent the same operation without 3DVT. RESULTS The 3DVT can be used to analyze the location of the breast tumors and determine the excision extension of the breast precisely. Compared to group B, group A had the advantage of less bleeding, shortened operating time and earlier discharge (p < 0.05). The cosmetic results of group A were more satisfactory than those of group B (p < 0.05). After a postoperative follow-up of 6-30 months, none of the patients in either group showed any signs of recurrence. CONCLUSIONS 3DVT can be used to design the surgical process preoperatively and results in positive therapeutic and cosmetic outcomes in EBCS and pedicled omentum for immediate breast reconstruction.

Abstract
OBJECTIVE: There are several limitations with current methods of breast volume measurement; principally relating to assumption of fixed shape forms. This study, utilizing computer aided volume estimates, developed a new method using the digital mapping of breast area and compares results to existing techniques of breast volume measurement and actual breast volume. METHODS: 50 consecutive breast cancer patients had breast volume calculated from mammograms [craniocaudal (CC) and mediolateral oblique views]; using breast height, width, radius, area and compression thickness. Area was recorded using cursor measurement tool for AGFA® Impax™6 software. The new volumetric estimation is based on the basic formula for the volume of a solid. The technique was compared with three known breast volume estimation techniques. Subsequently, 15 patients undergoing mastectomy had pre-op breast volume calculated using this new method and 3 existing techniques; values were compared to fresh mastectomy weights/volumes. RESULTS: 50 patients, mean age 63.2 ± 14.4 (range 38-88) had breast volume estimation. The CC view appears to provide the best correlation with existing techniques. Scatterplots show a significant correlation of all the methods with the digital breast volume estimation method. Mastectomy volume compared with four breast volume techniques in n = 15, confined to the CC, shows good correlation between the digital technique and real volume. Scatterplots show significant correlation between digital breast volume estimation and mastectomy weight. CONCLUSION: This study provided a novel simple tool to estimate breast volume in patients. ADVANCES IN KNOWLEDGE: This may aid in planning cosmetic outcome and oncoplastic approaches in breast cancer and breast reduction surgery.

Abstract
Screening mammography increases detection of non-palpable breast lesions requiring image-guided localization prior to surgery. Accurate preoperative localization is crucial for successful surgical outcomes. Wire-guided localization is currently the most widely used localization method for non-palpable breast lesions; however, this technique has multiple disadvantages including patient discomfort, possible wire transection and migration, suboptimal surgical incision placement due to wire location and limited scheduling flexibility decreasing operating room efficiency. As a result, promising new techniques including radioactive seed localization, non-radioactive radar localization and magnetic seed localization have been developed as alternatives. In this article, we provide an overview of these techniques and discuss their advantages, drawbacks and currently available outcome data.

Abstract
Purpose Neoadjuvant chemotherapy (NACT) is increasingly used in breast cancer treatment. One of the main goals of NACT is to reduce the extent of local surgery of the breast and axilla. The aim of this study was to determine surgical outcomes for patients receiving breast-conserving therapy (BCT) after NACT, including margin status plus secondary surgeries, excision volumes, and cosmetic outcomes. Methods A systematic review was performed in accordance with PRISMA principles. Pubmed, MEDLINE, Embase, and the Cochrane Library were searched for studies investigating the results of BCT following NACT. The main study outcomes were margin status, additional local therapies, excision volumes, and cosmetic outcomes. Non-comparative studies on NACT were also included. Exclusion criteria were studies with less than 25 patients, and studies excluding secondary mastectomy patients. Findings Of the 1219 studies screened, 26 studies were deemed eligible for analysis, including data from 5379 patients treated with NACT and 10,110 patients treated without NACT. Included studies showed wide ranges of tumor-involved margins (2–39.8%), secondary surgeries (0–45.4%), and excision volumes (43.2–268 cm3) or specimen weight (26.4–233 g) after NACT. Most studies were retrospective, with a high heterogeneity and a high risk of bias. Cosmetic outcomes after NACT were reported in two single-center cohort studies. Both studies showed acceptable cosmetic outcomes. Interpretation There is currently insufficient evidence to suggest that NACT improves surgical outcomes of BCT. It is imperative that clinical trials include patient outcome measures in order to allow monitoring and meaningful comparison of treatment outcomes in breast cancer.

Abstract
This study aimed to determine the efficacy of intraoperative ultrasonography-guided wire localization guided breast-conserving surgery (BCS) for nonpalpable breast cancer and compare it to conventional preoperative wire localization (PWL) guided surgery.We retrospectively analyzed the medical charts of 214 consecutive nonpalpable breast cancer patients who underwent BCS using intraoperative ultrasonography-guided wire localization by a surgeon (IUWLS) and PWL, between April 2013 and March 2017. Positive surgical margins, reexcision rates, and resection volumes were investigated.Of the total cohort, 124 patients underwent BCS with IUWLS and 90 patients with PWL. The following did not differ between the IUWLS and PWL groups: positive margin status, re-excision rate, conversion rate, permanent positive margin status, reoperation rate, median optimal resection volume (ORV), median total resection volume (TRV), and median closest tumor-free margin. Rather, median (range) widest tumor-free margin was significantly smaller in the IUWLS group (9 mm [5-12]) than in the PWL group (14 mm [9-20]; P = .003]). Median (range) calculated resection ratio (CRR) was significantly lower in the IUWLS group (1.67 [0.87-9.38]) than in the PWL group (4.83 [1.63-21.04]; P = .02).In nonpalpable breast cancer patients undergoing BCS, IUWLS showed positive resection margins and reexcision rates equivalent to those of the conventional PWL method. Additionally, excision volume and widest tumor-free margin were smaller with IUWLS, confirming that healthy breast tissue is less likely to be resected with this method. Our results suggest that IUWLS offers an excellent alternative to PWL, while avoiding PWL-induced patient discomfort.

[PMID: 27916314 DOI: 10.1016/j.ejso.2016.11.004] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2016] [Revised: 10/18/2016] [Accepted: 11/03/2016] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND The multicenter randomized controlled COBALT trial demonstrated that ultrasound-guided breast-conserving surgery (USS) results in a significant reduction of margin involvement (3.1% vs. 13%) and excision volumes compared to palpation-guided surgery (PGS). The aim of the present study was to determine long term oncological and patient-reported outcomes including quality of life (QoL), together with their progress over time. METHODS 134 patients with T1-T2 breast cancer were randomized to USS (N = 65) or PGS (N = 69). Cosmetic outcomes were assessed with the Breast Cancer Conservative Treatment cosmetic results (BCCT.core) software, panel-evaluation and patient self-evaluation on a 4-point Likert-scale. QoL was measured using the EORTC QLQ-C30/-BR23 questionnaire. RESULTS No locoregional recurrences were reported after mean follow-up of 41 months. Seven patients (5%) developed distant metastatic disease (USS 6.3%, PGS 4.4%, p = 0.466), of whom six died of disease (95.5% overall survival). USS achieved better cosmetic outcomes compared to PGS, with poor outcomes of 11% and 21% respectively, a result mainly attributable to mastectomies due to involved margins following PGS. There was no difference after 1 and 3 years in cosmetic outcome. Dissatisfied patients included those with larger excision volumes, additional local therapies and worse QoL. Patients with poor/fair cosmetic outcomes scored significantly lower on aspects of QoL, including breast-symptoms, body image and sexual enjoyment. CONCLUSION By significantly reducing positive margin status and lowering resection volumes, USS improves the rate of good cosmetic outcomes and increases patient-satisfaction. Considering the large impact of cosmetic outcome on QoL, USS has great potential to improve QoL following breast-conserving therapy.

Abstract
Background Ultrasound-guided breast-conserving surgery (USS) results in a significant reduction in both margin involvement and excision volumes (COBALT trial). Objective The aim of the present study was to determine whether USS also leads to improvements in cosmetic outcome and patient satisfaction when compared with standard palpation-guided surgery (PGS). Methods A total of 134 patients with T1–T2 invasive breast cancer were included in the COBALT trial (NTR2579) and randomized to either USS (65 patients) or PGS (69 patients). Cosmetic outcomes were assessed by a three-member panel using computerized software Breast Cancer Conservative Treatment cosmetic results (BCCT.core) and by patient self-evaluation, including patient satisfaction. Time points for follow-up were 3, 6, and 12 months after surgery. Overall cosmetic outcome and patient satisfaction were scored on a 4-point Likert scale (excellent, good, fair, or poor), and outcomes were analyzed using a multilevel, mixed effect, proportional odds model for ordinal responses. Results Ultrasound-guided breast-conserving surgery achieved better cosmetic outcomes, with 20 % excellence overall and only 6 % rated as poor, whereas 14 % of PGS outcomes were rated excellent and 13 % as poor. USS also had consistently lower odds for worse cosmetic outcomes (odds ratio 0.55, p = 0.067) than PGS. The chance of having a worse outcome was significantly increased by a larger lumpectomy volume (ptrend = 0.002); a volume >40 cc showed odds 2.78-fold higher for a worse outcome than a volume ≤40 cc. USS resulted in higher patient satisfaction compared with PGS. Conclusion Ultrasound-guided breast-conserving surgery achieved better overall cosmetic outcomes and patient satisfaction than PGS. Lumpectomy volumes >40 cc resulted in significantly worse cosmetic outcomes.

Ultrasound-guided breast-conserving surgery for early-stage palpable and nonpalpable invasive breast cancer: decreased excision volume at unchanged tumor-free resection margin. Breast Cancer Res Treat 2016; 158:535-41.

Abstract
Ultrasound guidance (USG) during breast-conserving surgery improves tumor-free surgical resection margins. The objective of this study was to evaluate whether USG reduces resection volumes without compromising margin status. 134 patients with palpable or nonpalpable T1-2N0-1 invasive breast cancer were treated with USG and compared with a historical reference control group (CON) consisting of palpation-guided (PAG) or wire-guided localization (WIG) breast-conserving surgery. Primary outcomes were excess resection volume and clear margin status, and secondary outcome was re-excision rate. 66 patients underwent USG. In the CON group (n = 68), PAG was performed in 24 (35 %) and WIG in 44 (64 %) patients. Median excision volume [39 (IQR 20-66) vs 56 (38-94) cm(3); p = 0.001] and median calculated resection ratio [1.7 (1.0-2.9) vs 2.8 (1.4-4.6) (p = 0.005)] were significantly smaller in the USG than in the CON group. Median minimal distance to the resection margin [4 mm (IQR 2-5 mm) vs 2 mm (1-4 mm), p = 0.004] was significantly larger. Clear resection margins were achieved in 58 of the USG patients (88 %) and in 58 of the CON patients (86 %) (p = 0.91); this was true in patients with palpable as well as nonpalpable lesions. Reexcision was needed in 6.1 and 7.2 % respectively. Relative risk for re-excision in the USG group was 0.82 (95 % CI 0.23-2.93). In patients with palpable and nonpalpable breast cancers, USG allows for lower excision volume and reduced resection of healthy breast tissue, without increased re-excision rate.

Abstract
The primary goal of breast-conserving surgery (BCS) is to obtain tumour-free resection margins. Margins positive or focally positive for tumour cells are associated with a high risk of local recurrence, and in the case of tumour-positive margins, re-excision or even mastectomy are sometimes needed to achieve definite clear margins. Unfortunately, tumour-involved margins and re-excisions after lumpectomy are still reported in up to 40% of patients and additionally, unnecessary large excision volumes are described. A secondary goal of BCS is the cosmetic outcome and one of the main determinants of worse cosmetic outcome is a large excision volume. Up to 30% of unsatisfied cosmetic outcome is reported. Therefore, the search for better surgical techniques to improve margin status, excision volume and consequently, cosmetic outcome has continued. Nowadays, the most commonly used localization methods for BCS of non-palpable breast cancers are wire-guided localization (WGL) and radio-guided localization (RGL). WGL and RGL are invasive procedures that need to be performed pre-operatively with technical and scheduling difficulties. For palpable breast cancer, tumour excision is usually guided by tactile skills of the surgeon performing “blind” surgery. One of the surgical techniques pursuing the aims of radicality and small excision volumes includes intra-operative ultrasound (IOUS). The best evidence available demonstrates benefits of IOUS with a significantly high proportion of negative margins compared with other localization techniques in palpable and non-palpable breast cancer. Additionally, IOUS is non-invasive, easy to learn and can centralize the tumour in the excised specimen with low amount of healthy breast tissue being excised. This could lead to better cosmetic results of BCS. Despite the advantages of IOUS, only a small amount of surgeons are performing this technique. This review aims to highlight the position of ultrasound-guided surgery for malignant breast tumours in the search for better oncological and cosmetic outcomes.

A nationwide pathology study on surgical margins and excision volumes after breast-conserving surgery: There is still much to be gained. Breast 2015; 25:14-21. [PMID: 26801411 DOI: 10.1016/j.breast.2015.11.003] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2015] [Revised: 10/23/2015] [Accepted: 11/14/2015] [Indexed: 01/08/2023] Open
Abstract
AIM OF THE STUDY The current study aims to assess margin status in relation to amount of healthy breast tissue resected in breast-conserving surgery (BCS) on a nationwide scale. METHODS Using PALGA (a nationwide network and registry of histology and cytopathology in the Netherlands), all patients who underwent BCS for primary invasive carcinoma in 2012-13 were selected (10,058 excerpts). 9276 pathology excerpts were analyzed for a range of criteria including oncological margin status and distance to closest margin, specimen weight/volume, greatest tumor diameter, and with or without localization method. Calculated resection ratios (CRR) were assessed to determine excess healthy breast tissue resection. RESULTS Margins for invasive carcinoma and in situ carcinoma combined were tumor-involved in 498 (5.4%) and focally involved in 1021 cases (11.0%) of cases. Unsatisfactory resections including (focally) involved margins and margins ≤ 1 mm were reported in 33.8% of patients. The median lumpectomy volume was 46 cc (range 1-807 cc; SD 49.18) and median CRR 2.32 (range 0.10-104.17; SD 3.23), indicating the excision of 2.3 the optimal resection volume. CONCLUSION The unacceptable rate of tumor-involved margins as well as margins ≤ 1 mm in one third of all patients is also achieved at the expense of healthy breast tissue resection, which may carry the drawback of high rates of cosmetic failure. These data clearly suggest the need for improvement in current breast conserving surgical procedures to decrease tumor-involved margin rates while reducing the amount of healthy breast tissue resected.

Abstract
BACKGROUND The purpose of this study was to evaluate ultrasound-guided surgery for palpable breast cancer by comparing the standard palpation-guided surgery in terms of the extent of healthy breast tissue resection, the percentage of tumor-free margins, and cosmetic outcomes. METHODS This was a prospective, observational cohort study conducted from January 2009 to July 2011. Breast cancer patients, diagnosed via biopsy, were operated in guidance with either ultrasound or palpation. Patient demographics, tumor features, intraoperative findings, pathologic and cosmetic results, intraoperative-measured ultrasound margins, and pathology margins were compared. RESULTS Ultrasound (US)-guided lumpectomy was performed on 84 women and palpation-guided lumpectomy on 80 women. Patient demographics and tumor characteristics showed no differences. The rate of re-excision was 17 % for the palpation-guided surgery group, and 6 % for the US-guided group (p = 0.03). There was good correlation between the closest margins recorded by US and pathology margins (r = 0.76, p = 0.01). Volume of resection was significantly larger in the palpation-guided group despite the similar size of tumors (p = 0.048). Cosmetic outcome of surgery was equivalent between groups. CONCLUSIONS Intraoperative ultrasound guidance for excision of palpable breast cancers is feasible and gives results in terms of pathologic margins that are comparable with those achieved by standard palpation-guided excisions.

Abstract
BACKGROUND Radioactive Seed Localization with a radioactive iodine-125 seed (RSL) and Radioguided Occult Lesion Localization with 99mTechnetium colloid (ROLL) are both attractive alternatives to wire localization for guiding breast conserving surgery (BCS) of non-palpable breast cancer. The aim of this study was to evaluate and compare the efficacy of RSL and ROLL. METHODS We retrospectively analyzed 387 patients with unifocal non-palpable ductal carcinoma in situ (DCIS) or invasive carcinoma treated with BCS at the Netherlands Cancer Institute. In total 403 non-palpable lesions were localized either by RSL (N = 128) or by ROLL (N = 275). Primary outcome measures were positive margins and re-excision rates; the secondary outcome measure was weight of the specimen. RESULTS Pre-operative mammography or ultrasound showed similar sizes of DCIS and invasive tumours in both RSL and ROLL groups. In the RSL group, more lesions were DCIS (58%) than in the ROLL group, where 32% of the lesions were pure DCIS. The proportions of focally positive margins (11% vs. 10%) and more than focally positive margins (9% vs. 9%) were comparable between the RSL and the ROLL group, resulting in the same re-excision rate in both RSL and ROLL groups (9% vs. 10%). For DCIS lesions, the specimen weight was significantly lower in the RSL group than in the ROLL group after adjusting for tumour size on mammography (12 g; 95% CI 2.6-21). CONCLUSION Margin status and re-excision rates were comparable for RSL and ROLL in patients with non-palpable breast lesions. Because of the significant lower weight of the resected specimen in DCIS, the feasibility of position verification of the I-125 seed and more convenient logistics, we favour RSL over ROLL to guide breast-conserving therapy.

Abstract
BACKGROUND Preoperative objective predictions of cosmetic result after breast conserving surgery (BCS) has the potential to aid in surgical treatment decision making. Our aim was to investigate the predictive value of tumor volume in relation to breast volume (TV/BV ratio) for cosmetic result. METHODS Sixty-nine invasive breast cancer women with preoperative MRI and treated by BCS and radiotherapy in 2007-2012 were prospectively included. Simple excision or basic oncoplastic techniques were used, but no volume displacement. TV/BV ratio was measured in the MRI while 3D-projected in virtual reality environment (I-Space). Cosmetic result was assessed by patient questionnaire, panel evaluation, and breast retraction assessment (BRA). Quality-of-life was assessed by EORTC QLQ-C30 and BR23. RESULTS Intraobserver and interobserver correlation coefficients for tumor and breast volume were all >0.95. Increasing TV/BV ratio correlated with decreasing cosmetic result as determined by patient, panel, and BRA. TV/BV ratio was a significant independent predictor for the panel evaluation (P=0.028), as was tumor location (P<0.05), and together they constituted a good prediction model (AUC 0.83). CONCLUSIONS TV/BV ratio was a precise and independent predictor for cosmetic result determined by a panel and can be used as preoperative prediction tool to enable more informed surgical treatment decision making.

Cosmetic Outcome Assessment following Breast-Conserving Therapy: A Comparison between BCCT.core Software and Panel Evaluation. Int J Breast Cancer 2014; 2014:716860. [PMID: 25328712 PMCID: PMC4190270 DOI: 10.1155/2014/716860] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2014] [Accepted: 09/09/2014] [Indexed: 11/18/2022] Open
Abstract
Purpose. Over recent decades, no consensus has yet been reached on the optimal approach to cosmetic evaluation following breast-conserving therapy (BCT). The present study compared the strengths and weaknesses of the BCCT.core software with a 10-member panel from various backgrounds. Methods. Digital photographs of 109 consecutive patients after BCT were evaluated for 7 items by a panel consisting of 2 breast surgeons, 2 residents, 2 laypersons, and 4 plastic surgeons. All photographs were objectively evaluated using the BCCT.core software (version 20), and an overall cosmetic outcome score was reached using a four-point Likert scale. Results. Based on the mean BCCT.core software score, 41% of all patients had fair or poor overall cosmetic results (10% poor), compared with 51% (14% poor) obtained with panel evaluation. Mean overall BCCT.core score and mean overall panel score substantially agreed (weighted kappa: 0.68). By contrast, analysis of the evaluation of scar tissue revealed large discrepancies between the BCCT.core software and the panel. The analysis of subgroups formed from different combinations of the panel members still showed substantial agreement with the BCCT.core software (range 0.64-0.69), independent of personal background. Conclusions. Although the analysis of scar tissue by the software shows room for improvement, the BCCT.core represents a valid and efficient alternative to panel evaluation.

Abstract
Inaccuracies in intraoperative tumor localization and evaluation of surgical margin status result in suboptimal outcome of breast-conserving surgery (BCS). Optical imaging, in particular near-infrared fluorescence (NIRF) imaging, might reduce the frequency of positive surgical margins following BCS by providing the surgeon with a tool for pre- and intraoperative tumor localization in real-time. In the current study, the potential of NIRF-guided BCS is evaluated using tissue-simulating breast phantoms for reasons of standardization and training purposes. Breast phantoms with optical characteristics comparable to those of normal breast tissue were used to simulate breast conserving surgery. Tumor-simulating inclusions containing the fluorescent dye indocyanine green (ICG) were incorporated in the phantoms at predefined locations and imaged for pre- and intraoperative tumor localization, real-time NIRF-guided tumor resection, NIRF-guided evaluation on the extent of surgery, and postoperative assessment of surgical margins. A customized NIRF camera was used as a clinical prototype for imaging purposes. Breast phantoms containing tumor-simulating inclusions offer a simple, inexpensive, and versatile tool to simulate and evaluate intraoperative tumor imaging. The gelatinous phantoms have elastic properties similar to human tissue and can be cut using conventional surgical instruments. Moreover, the phantoms contain hemoglobin and intralipid for mimicking absorption and scattering of photons, respectively, creating uniform optical properties similar to human breast tissue. The main drawback of NIRF imaging is the limited penetration depth of photons when propagating through tissue, which hinders (noninvasive) imaging of deep-seated tumors with epi-illumination strategies.

Abstract
SUMMARY Breast cancer surgery has changed dramatically from the en bloc removal of the breast to the less invasive breast-conserving surgery. The recent COBALT trial comparing ultrasound-guided surgery with palpation-guided surgery for palpable breast cancer showed less margin involvement and decreased excision volumes with ultrasonography, which resulted in less additional therapy and possibly improved cosmetic outcome. Other surgical techniques pursuing these same aims have been developed over the past two decades and are referred to as oncoplastic surgery. Unfortunately oncoplastic surgery lacks sufficient evidence to corroborate its widespread implementation and should thereby solely be applied to selected cases. This review aims to highlight the position of ultrasound-guided surgery from a perspective of breast-conserving surgery in the search for better oncological and cosmetic outcomes.

Abstract
BACKGROUND To determine the therapeutic and cosmetic outcomes of patients with breast cancer treated with endoscopic axillary lymphadenectomy (EAL) combined with laparoscopically harvested pedicled omentum (LHPO) for immediate breast reconstruction. METHODS Forty patients with early breast cancer underwent EAL, followed by quadrantectomy and LHPO for immediate breast reconstruction. All patients were evaluated for operating time, blood loss, postoperative hospital stay, complications, etc. The cosmetic outcomes were evaluated 6 months after the surgery, according to the Harris criteria. RESULTS The average operating time was 308 min, including 39 min for EAL, 63 min for quadrantectomy, and 58 min for LHPO. The average blood loss was 70 ml, and was mainly incurred during breast resection. On average, the patients were discharged 9.5 days after the surgery. Partial graft necrosis and omental fat liquefaction occurred in one patient each. No other complications occurred after the surgery. No local recurrence or distant metastasis was found during the follow-up. The cosmetic results were mostly satisfactory. No size reduction of the reconstructed breast occurred after radiation therapy. Esthetic evaluation of the reconstructed breast showed that the cosmetic outcome was "excellent" in 35 patients, "good" in 4 patients, and "fair" in 1 patient. CONCLUSIONS EAL combined with LHPO for breast reconstruction is a viable, safe procedure that causes minimal surgical trauma and results in a soft, shapely breast postoperatively.

Abstract
The primary goal of breast conserving surgery or mastectomy is the prevention of recurrent breast cancer. The distinguishing goal of breast conserving surgery is preservation of a breast as normal in appearance as possible. If the margins of the excised breast cancer extend to the border of the excised specimen one cannot determine the amount of gross tumor that was not excised. Retrospective analyses of surgical series show a 2-3 fold increase in local recurrence of the breast tumor if the margin is positive under the microscope, even when the surgeon believed it to be clear on gross examination. This fact has led to a variety of techniques attempting to ensure that the margins of the excised specimen are free of obvious tumor including pre-operative and specimen imaging and mapping, neo-adjuvant therapy to shrink the primary tumor, touch-prep and frozen section of the specimen margins during the procedure, shaving additional margins about the specimen at the closest aspects grossly or on all six surfaces, and examinations of the in situ walls of the remaining breast with new instrumentation. An obvious approach to diminishing the likelihood of positive specimen margins is taking a wider margin of normal tissue. As the volume of resected breast increases by the cube of the radius of excised tissue, this tracks all too well with diminishing cosmetic results and patient approval of the conserved breast. The question posed regards the finding of a positive or close margin after the surgical procedure. The finding of a positive margin can be parsed to a microscopic focus of tumor at the margin vs. the margin inking on a tumor surface. The latter demands re-excision despite the morbidity involved barring an extraordinary contra-indication or patient refusal. It represents the very real possibility of sufficient residual gross tumor in the breast that even with systemic therapy and breast irradiation the tumor will be un-controlled. A microscopic focus separated from the bulk of the primary tumor and adjacent to a margin has not been shown to carry such risk. The margin of normal tissue beyond the primary tumor that significantly reduces the risk of local recurrence remains undefined. Sufficient data are available to say that in the era of systemic therapy, excellent radiation therapy techniques, and boost doses when indicated, no margin of normal breast tissue beyond the tumor has been shown to be clearly superior to a layer of cells between the ink and the tumor. The larger the tumor and the more aggressive its biology is judged to be the lower the confidence that a single layer of cells at the point of histologic study accurately represents a clear margin. As in all medical decisions wise judgment must integrate all of the known factors to reach the best recommendation. There are few circumstances that would warrant a second surgical procedure for a close but clear margin today.

Abstract
INTRODUCTION The aim of this study was to determine the efficacy of ultrasonography (US)-guided excision of palpable breast cancer and to compare it with the standard palpation-guided breast-conserving surgery (BCS). METHODS For this purpose, 335 women with palpable breast cancer who underwent BCS were retrospectively studied. The positive surgical margins and re-excision rates were investigated. RESULTS Of the total cohort, 137 patients were treated with palpation-guided BCS and 198 underwent US-guided tumor excision. The tumor and patient characteristics were similar in both groups. Patient age, postmenopausal status, tumor size, histological grade, intraductal tumor component, lobular histology, and palpation-guided tumor excision were associated with increased risk of positive margins. The shave margins were re-excised at the time of original operation more often by palpation-guided localization (28.5%) than by the US-guided procedure (11.1%) (P < .0001). A surgeon was able to correctly identify the "problematic" margin in 81.1% of cases via intraoperative US and in only 17.9% via palpation (P < .0001). The re-excision rate during a second operation was significantly reduced by US-guided tumorectomy (P = .004). Of 198 patients in the US-guided group, 23 (11.6%) underwent a second operation, as did 33 of 137 patients in the palpation group (24.1%). The sensitivity and specificity of US-guided excisions were 52.7% and 97.5%, respectively, whereas the sensitivity and the specificity of palpation-guided tumor excisions were 15.5% and 65.9%, respectively. CONCLUSION US-guided BCS is superior to palpation-guided excision in predicting the closest margins, obtaining clear surgical margins, and reducing re-operations.

Abstract
Purpose Margin status is one of the most important predictors of local recurrence after breast conserving surgery (BCS). Intraoperative ultrasound guidance (IOUS) has the potential to improve surgical accuracy for breast cancer. The purpose of the present meta-analysis was to determine the efficacy of IOUS in breast cancer surgery and to compare the margin status to that of the more traditional Guide wire localization (GWL) or palpation-guidance. Methods We searched the database of PubMed for prospective and retrospective studies about the impact of IOUS on margin status of breast cancer, and a meta-analysis was conducted. Results Of the 13 studies included, 8 were eligible for the impact of IOUS on margin status of non-palpable breast cancers, 4 were eligible for palpable breast cancers, and 1 was for both non-palpable and palpable breast cancers. The rate of negative margins of breast cancers in IOUS group was significantly higher than that in control group without IOUS (risk ratio (RR) = 1.37, 95% confidence interval (CI) = 1.18–1.59 from 7 prospective studies, odds ratio (OR) = 2.75, 95% CI = 1.66–4.55 from 4 retrospective studies). For non-palpable breast cancers, IOUS-guidance enabled a significantly higher rate of negative margins than that of GWL-guidance (RR = 1.26, 95% CI = 1.09–1.46 from 6 prospective studies; OR = 1.45, 95% CI = 0.86–2.43 from 2 retrospective studies). For palpable breast cancers, relative to control group without IOUS, the RR for IOUS associated negative margins was 2.36 (95% CI = 1.26–4.43) from 2 prospective studies, the OR was 2.71 (95% CI = 1.25–5.87) from 2 retrospective studies. Conclusion This study strongly suggests that IOUS is an accurate method for localization of non-palpable and palpable breast cancers. It is an efficient method of obtaining high proportion of negative margins and optimum resection volumes in patients undergoing BCS.

Abstract
Perfluoropentane gas filled iron-silica nanoshells have been developed as stationary ultrasound contrast agents for marking tumors to guide surgical resection. It is critical to establish their long-term imaging efficacy, as well as biodistribution. This work shows that 500 nm Fe-SiO2 nanoshells can be imaged by color Doppler ultrasound over the course of 10 days in Py8119 tumor bearing mice. The 500 nm nonbiodegradable SiO2 and biodegradable Fe-SiO2 nanoshells were functionalized with diethylenetriamine pentaacetic acid (DTPA) ligand and radiolabeled with (111)In(3+) for biodistribution studies in nu/nu mice. The majority of radioactivity was detected in the liver and kidneys following intravenous (IV) administration of nanoshells to healthy animals. By contrast, after nanoshells were injected intratumorally, most of the radioactivity remained at the injection site; however, some nanoshells escaped into circulation and were distributed similarly as those given intravenously. For intratumoral delivery of nanoshells and IV delivery to healthy animals, little difference was seen between the biodistribution of SiO2 and biodegradable Fe-SiO2 nanoshells. However, when nanoshells were administered IV to tumor bearing mice, a significant increase was observed in liver accumulation of SiO2 nanoshells relative to biodegradable Fe-SiO2 nanoshells. Both SiO2 and Fe-SiO2 nanoshells accumulate passively in proportion to tumor mass, during intravenous delivery of nanoshells. This is the first report of the biodistribution following intratumoral injection of any biodegradable silica particle, as well as the first report demonstrating the utility of DTPA-(111)In labeling for studying silica nanoparticle biodistributions.

Abstract
BACKGROUND The development of intraoperative sentinel node biopsy (SLNB) analysis methods, such as One-Step Nucleic Acid Amplification (OSNA), has made single-stage procedures possible. AIMS We investigated the incidence of OSNA-detected lymph node positivity, comparing it to conventional histopathology, the incidence of non-SLNB node disease for the OSNA positive patients, and the breast re-operation rate, to assess the benefit from single-stage procedures. METHODS This was a single-centre series of 573 consecutive patients undergoing SLNB (173 histopathology and 400 OSNA). RESULTS OSNA-detected SLNB macrometastasis was similar to routine histopathology, with more micrometastasis detected (p < 0.001). Non-SLNB involvement in the OSNA group was similar to documented histopathological series. 27.6% of OSNA patients avoided further surgery because of OSNA. The median time for OSNA results was 42 min. CONCLUSIONS OSNA is an effective method for detecting SLNB-metastasis. It is easily used in clinical practice, providing reliable results and negating the need for a second axillary operation.

Abstract
BACKGROUND Breast-conserving surgery for palpable breast cancer is associated with tumour-involved margins in up to 41% of cases and excessively large excision volumes. Ultrasound-guided surgery has the potential to resolve both of these problems, thereby improving surgical accuracy for palpable breast cancer. We aimed to compare ultrasound-guided surgery with the standard for palpable breast cancer-palpation-guided surgery-with respect to margin status and extent of healthy breast tissue resection. METHODS In this randomised controlled trial, patients with palpable T1-T2 invasive breast cancer were recruited from six medical centres in the Netherlands between October, 2010, and March, 2012. Eligible participants were randomly assigned to either ultrasound-guided surgery or palpation-guided surgery in a 1:1 ratio via a computer-generated random sequence and were stratified by study centre. Patients and investigators were aware of treatment assignments. Primary outcomes were surgical margin involvement, need for additional treatment, and excess healthy tissue resection (defined with a calculated resection ratio derived from excision volume and tumour diameter). Data were analysed by intention to treat. This trial is registered at http://www.TrialRegister.nl, number NTR2579. FINDINGS 134 patients were eligible for random allocation. Two (3%) of 65 patients allocated ultrasound-guided surgery had tumour-involved margins compared with 12 (17%) of 69 who were assigned palpation-guided surgery (difference 14%, 95% CI 4-25; p=0·0093). Seven (11%) patients who received ultrasound-guided surgery and 19 (28%) of those who received palpation-guided surgery required additional treatment (17%, 3-30; p=0·015). Ultrasound-guided surgery also resulted in smaller excision volumes (38 [SD 26] vs 57 [41] cm(3); difference 19 cm(3), 95% CI 7-31; p=0·002) and a reduced calculated resection ratio (1·0 [SD 0·5] vs 1·7 [1·2]; difference 0·7, 95% CI 0·4-1·0; p=0·0001) compared with palpation-guided surgery. INTERPRETATION Compared with palpation-guided surgery, ultrasound-guided surgery can significantly lower the proportion of tumour-involved resection margins, thus reducing the need for re-excision, mastectomy, and radiotherapy boost. By achieving optimum resection volumes, ultrasound-guided surgery reduces unnecessary resection of healthy breast tissue and could contribute to improved cosmetic results and quality of life.

Abstract
BACKGROUND We sought to determine the re-excision rate following lumpectomy for palpable breast cancers using intraoperative ultrasound (US). A secondary aim was to investigate the impact on surgical decision-making. METHODS We identified 73 women who underwent US-guided lumpectomy for palpable breast cancer between 2006 and 2010. A cohort of 124 women who underwent palpation-guided lumpectomy was used for a comparison group. Data included patient demographics, tumor characteristics, intraoperative findings, and pathologic outcomes. Descriptive statistics were used for data summary and compared by chi-square or t test, as appropriate. RESULTS A total of 73 women underwent US-guided lumpectomy, and 124 women underwent palpation-guided lumpectomy (median age 55 years). Patients undergoing palpation-guided lumpectomy had smaller tumors that were more likely to be HER2/neu amplified compared with patients undergoing US-guided lumpectomy (P < 0.05 for each). There were no differences between the 2 groups with respect to patient age, tumor grade, and estrogen/progesterone receptor status (P > 0.05 for each). Re-excision rates were similar in both groups [17 (23%) in the US group versus 31 (25%) in the palpation group; P > 0.05]. In the US group, 45 patients (62%) had additional shave margins taken based on US interrogation of the specimen, and 12 patients (16%) were spared a 2nd procedure based on the use of intraoperative US. CONCLUSIONS Although palpable breast cancers can be excised based on direct palpation or needle localization, we believe that US guidance provides an excellent tool to aid the breast surgeon. Only 10% of patients had a positive margin on final pathology as a result, and the overall re-excision rate was acceptable.
