Diagnostic accuracy of intraoperative methods for margin assessment in breast cancer surgery: A systematic review & meta-analysis. Breast 2024; 76:103749. [PMID: 38759577 PMCID: PMC11127275 DOI: 10.1016/j.breast.2024.103749] [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: 01/25/2024] [Revised: 04/23/2024] [Accepted: 05/10/2024] [Indexed: 05/19/2024] Open
Abstract
PURPOSE There are a wide variety of intraoperative techniques available in breast surgery to achieve low rates for positive margins of excision. The objective of this systematic review was to determine the pooled diagnostic accuracy of intraoperative breast margin assessment techniques that have been evaluated in clinical practice. METHODS This study was performed in accordance with PRISMA guidelines. A systematic search of the literature was conducted to identify studies assessing the diagnostic accuracy of intraoperative margin assessment techniques. Only clinical studies with raw diagnostic accuracy data as compared with final permanent section histopathology were included in the meta-analysis. A bivariate model for diagnostic meta-analysis was used to determine overall pooled sensitivity and specificity. RESULTS Sixty-one studies were eligible for inclusion in this systematic review and meta-analysis. Cytology demonstrated the best diagnostic accuracy, with pooled sensitivity of 0.92 (95 % CI 0.77-0.98) and a pooled specificity of 0.95 (95 % CI 0.90-0.97). The findings also indicate good diagnostic accuracy for optical spectroscopy, with a pooled sensitivity of 0.86 (95 % CI 0.76-0.93) and a pooled specificity of 0.92 (95 % CI 0.82-0.97). CONCLUSION Pooled data indicate that optical spectroscopy, cytology and frozen section have the greatest diagnostic accuracy of currently available intraoperative margin assessment techniques. However, long turnaround time for results and their resource intensive nature has prevented widespread adoption of these methods. The aim of emerging technologies is to compete with the diagnostic accuracy of these established techniques, while improving speed and usability.

[PMID: 37991190 PMCID: PMC10776367 DOI: 10.1093/bjs/znad335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Revised: 08/21/2023] [Accepted: 09/28/2023] [Indexed: 11/23/2023]
Abstract
INTRODUCTION Different intraoperative techniques with varying levels of evidence are available to decrease positive surgical margins during breast conserving surgery. The aim of this review is to assess the effectiveness of the MarginProbe® device as an intraoperative adjunct tool in reducing positive surgical margins, and subsequently exploring the effect on patient re-excision rates. METHODOLOGY A systematic review of the available medical literature was conducted from 2007 to March 2022. A literature search of Cochrane, PubMed and Embase by two independent reviewers reviwers was performed to identify eligible articles looking at the primary outcome of percentage reduction in patient re-excision rates using MarginProbe®. Secondary outcomes analysed were comparison of tissue volume removed, absolute and relative reduction in re-excision rate, cosmetic outcome, as well as MarginProbe® sensitivity and specificity. RESULTS A total of 12 full text articles were identified. An independent samples t-test using a total of 2680 patients found a 54.68 per cent reduction in re-excision rate with the use of MarginProbe®, which was statistically significant with a large effect size (P < 0.001; d = 1.826). Secondary outcomes showed a relatively higher sensitivity of the MarginProbe® device, at the expense of decreased specificity, and no significant impact on cosmesis and volume of breast tissue excised. CONCLUSION MarginProbe® is an effective intraoperative adjunct in breast-conservation surgery that reduces patient re-excision rates, with no adverse effects relating to breast cosmesis or increase in volume of excised tissue.

Conventional specimen radiography in breast-conserving therapy: a useful tool for intraoperative margin assessment after neoadjuvant therapy? Breast Cancer Res Treat 2023:10.1007/s10549-023-06976-2. [PMID: 37302085 DOI: 10.1007/s10549-023-06976-2] [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: 02/22/2023] [Accepted: 05/06/2023] [Indexed: 06/13/2023]
Abstract
PURPOSE A previous study in our breast unit showed that the diagnostic accuracy of intraoperative specimen radiography and its potential to reduce second surgeries in a cohort of patients treated with neoadjuvant chemotherapy were low, which questions the routine use of Conventional specimen radiography (CSR) in this patient group. This is a follow-up study in a larger cohort to further evaluate these findings. METHODS This retrospective study included 376 cases receiving breast-conserving surgery (BCS) after neoadjuvant chemotherapy (NACT) of primary breast cancer. CSR was performed to assess potential margin infiltration and recommend an intraoperative re-excision of any radiologically positive margin. The histological workup of the specimen served as gold standard for the evaluation of the accuracy of CSR and the potential reduction of second surgeries by CSR-guided re-excisions. RESULTS 362 patients with 2172 margins were assessed. The prevalence of positive margins was 102/2172 (4.7%). CSR had a sensitivity of 37.3%, a specificity of 85.6%, a positive predictive value (PPV) of 11.3%, and a negative predictive value (NPV) of 96.5%. The rate of secondary procedures was reduced from 75 to 37 with a number needed to treat (NNT) of CSR-guided intraoperative re-excisions of 10. In the subgroup of patients with clinical complete response (cCR), the prevalence of positive margins was 38/1002 (3.8%), PPV was 6.5% and the NNT was 34. CONCLUSION This study confirms our previous finding that the rate of secondary surgeries cannot be significantly reduced by CSR-guided intraoperative re-excisions in cases with cCR after NACT. The routine use CSR after NACT is questionable, and alternative tools of intraoperative margin assessment should be evaluated.

Abstract
INTRODUCTION Up to 30% of patients undergoing lumpectomy for breast cancer are in need for re-excision due to either close or involved margins. We evaluated the yield of Margin Probe© (MP; Dilon Technologies, USA) in a cohort of patients undergoing lumpectomy for both palpable and non-palpable tumors. METHODS Following lumpectomy, margins were evaluated with MP and readings were compared to the lumpectomies' pathological evaluation irrespective of whether additional margins were removed during surgery. Involved margins or the presence of DCIS within 1 mm of the resection margins were considered as positive margins. RESULTS 48 patients with 51 tumors underwent lumpectomy. Thirteen of the 51 lumpectomies had pathological close or involved margins. MP identified 3 out of the 13 positive margins. False-positive readings were recorded in 97 out of 287 margins. The sensitivity, specificity, positive predictive value and negative predictive value were 23.1% (95%CI 5.0% 53.8%), 66.4% (95%CI 60.7%-71.9%), 3% (95%CI 0.6%-8.5%), and 95.1% (95%CI 91.1%-97.6%) respectively. CONCLUSIONS MP cancer detection rate is relatively low while high false-positive rate leads to unnecessary shavings in almost all patients. Evaluation of MP performance should be based on comparing MP read to pathology report.

Abstract
OBJECTIVE We intend to provide an informative and up-to-date summary on the topic of intraoperative assessment of margins in breast conserving surgery (BCS). Conventional methods as well as cutting-edge technologies are analyzed for their advantages and limitations in the hope that clinicians can turn to this for reference. This review can also offer guidance for technicians in the future design of intraoperative margin assessment tools. BACKGROUND Achieving negative margins during BCS is one of the vital factors for preventing local recurrence. Conducting intraoperative margin assessment can ensure negative margins to a large extent and possibly relieve patients of the anguish of re-interventions. In recent years, innovative methods for margin assessment during BCS are advancing rapidly. And there is a lack of summary regarding the development of intraoperative margin assessment in BCS. METHODS A PubMed search with keywords "intraoperative margin assessment" and "breast conserving surgery" was conducted. Relevant publications were screened manually for its title, abstract and even full text to determine its true relevance. Publications on neo-adjuvant therapy and intraoperative radiotherapy were excluded. References from the searched articles and other supplementary articles were also looked into. CONCLUSIONS Conventional methods for margin assessment yields stable outcome but its use is limited because of the demand on pathology staff and the trade-off between time and precision. Conventional imaging techniques pass the workload to radiologists at the cost of a significantly low duration of time. Involving artificial intelligence for image-based assessment is a further improvement. However, conventional imaging is inherently flawed in that occult lesions can't show on the image and the showing ones are ambiguous and open to interpretation. Unconventional techniques which base their judgment on cellular composition are more reassuring. Nonetheless, unconventional techniques should be subjected to clinical trials before putting into practice. And studies regarding comparison between conventional methods and unconventional methods are also needed to evaluate their relative efficacy.

Abstract
INTRODUCTION Oncological surgery must follow some fundamental principles to be truly curative, one of which is the resection of the tumor with surgical margins free of neoplasia. In breast cancer, surgery with positive margins should be expanded immediately. There are probably different intensities, between the stages and molecular subtypes of operable breast cancer, of worsening prognosis due to the surgical margin compromised by the neoplasia in women not submitted to the necessary enlargement of the positive surgical margin. MATERIALS AND. METHODS Seven hundred and forty-seven women with invasive ductal carcinoma of the breast, analyzing anatomical-pathological information, types of surgery, molecular subtypes, and the presence or absence of the surgical margin compromised by neoplasia. RESULTS Sixty-one (8.2%) patients had positive surgical margin, causing 2.85 times more risk of locoregional relapse compared to negative surgical margin by multivariate analysis. In subgroup analysis, among stages I, II and III, stage II was the most negatively impacted, with those patients presenting 2.42 times more risk of distant metastasis and 4.94 times more risk of locoregional relapses compared to negative surgical margin by multivariate analysis. Among the molecular subtypes, Triple Negative tumors with a positive surgical margin had 3.56 times more risk of death, 4.98 times more risk of distant metastasis and 5.55 times more risk of locoregional relapse compared to negative surgical margin by multivariate analysis. CONCLUSIONS The positive surgical margin, especially in Stage II and Triple-Negative breast cancer patients negatively impact the patient's evolution, increasing risk of distant metastasis and death.

Abstract
SIGNIFICANCE Re-excision rates for women with invasive breast cancer undergoing breast conserving surgery (or lumpectomy) have decreased in the past decade but remain substantial. This is mainly due to the inability to assess the entire surface of an excised lumpectomy specimen efficiently and accurately during surgery. AIM The goal of this study was to develop a deep-ultraviolet scanning fluorescence microscope (DUV-FSM) that can be used to accurately and rapidly detect cancer cells on the surface of excised breast tissue. APPROACH A DUV-FSM was used to image the surfaces of 47 (31 malignant and 16 normal/benign) fresh breast tissue samples stained in propidium iodide and eosin Y solutions. A set of fluorescence images were obtained from each sample using low magnification (4 × ) and fully automated scanning. The images were stitched to form a color image. Three nonmedical evaluators were trained to interpret and assess the fluorescence images. Nuclear-cytoplasm ratio (N/C) was calculated and used for tissue classification. RESULTS DUV-FSM images a breast sample with subcellular resolution at a speed of 1.0 min / cm2. Fluorescence images show excellent visual contrast in color, tissue texture, cell density, and shape between invasive carcinomas and their normal counterparts. Visual interpretation of fluorescence images by nonmedical evaluators was able to distinguish invasive carcinoma from normal samples with high sensitivity (97.62%) and specificity (92.86%). Using N/C alone was able to differentiate patch-level invasive carcinoma from normal breast tissues with reasonable sensitivity (81.5%) and specificity (78.5%). CONCLUSIONS DUV-FSM achieved a good balance between imaging speed and spatial resolution with excellent contrast, which allows either visual or quantitative detection of invasive cancer cells on the surfaces of a breast surgical specimen.
