Objective: Image-guided percutaneous biopsy is the recommended initial diagnostic procedure for suspicious mammographic lesions. This study was conducted to determine the accuracy of the Intact(®) breast lesion excision system (BLES) and to identify predictive factors for complete excision and underestimation. Material and Methods: A prospective study was conducted between January 28, 2008 and April 30, 2009 on 166 biopsy procedures using Intact(®) biopsy device. Diagnoses obtained from biopsy specimen were compared with to final diagnosis on surgical excision specimen. Results: Of the 166 patients, 15 (9%) displayed lesions with cell atypia, 28 (17%) had an intra ductal carcinoma (IDC) and 9 (5%) had an invasive carcinoma. Eight of 15 patients with cell atypia had open surgical excision, and none showed underestimation. All patients with IDC underwent surgical excision: we found an invasive carcinoma in 6 cases (21.4% underestimation) and a complete removal of the lesion by the Intact(®) BLES in 11 cases (39%). All 9 patients with invasive carcinoma had a surgical excision, with 1 complete removal of the lesion by Intact(®) BLES. Multivariate analyses did not identify predictive factors for underestimation; clear margins ≥1mm on biopsy specimen was the only independent predictive factor of complete excision (OR=8.51, p=0.02). Conclusions: Intact(®) BLES provides a safe alternative to vacuum assisted core needle biopsy (VACNB) with an underestimation rate comparable to those previously reported for VACNB. The high rate of complete removal of the lesions, particularly ISC, offers an interesting perspective of avoiding subsequent excisional surgery for small lesions and thus requires further confirmational study.

Breast cancer is the most common female cancer in the world. Numerous studies have shown that the risk of metastatic disease increases with tumor volume. In this context, it is useful to assess whether the regular practice of formal breast self-examination (BSE) as opposed to breast awareness has an impact on the number of cancers diagnosed, their stage, the treatments used and mortality., Design: The Commission of Senology (CS) of the Collège National de Gynécologie et Obstétrique Français (CNGOF) respected and followed the Grading of Recommendations Assessment, Development and Evaluation method to assess the quality of the evidence on which the recommendations were based., Methods: The CS studied 16 questions individualizing four groups of women (general population, women aged over 75, high-risk women, and women previously treated for breast cancer). For each situation, it was determined whether the practice of BSE versus abstention from this examination led to detection of more breast cancers and/or recurrences and/or reduced treatment and/or increased survival., Results: BSE should not be recommended for women in the general population, who otherwise benefit from clinical breast examination by practitioners from the age of 25, and from organized screening from 50 to 74 (strong recommendation). In the absence of data on the benefits of BSE in patients aged over 75, for those at high risk and those previously treated for breast cancer, the CS was unable to issue recommendations. Thus, if women in these categories wish to undergo BSE, information on the benefits and risks observed in the general population must be given, notably that BSE is associated with a higher number of referrals, biopsies, and a reduced quality of life., Competing Interests: Declaration of competing interest The members of the steering committee, the redactors and the reviewers declare that they have no link of interest that could interfere with this work., (Copyright © 2023.

Background: Lipomodelling (LM) is an increasingly used technique to reconstruct or correct an aesthetic defect linked to a loss of substance. In France, the Haute Autorité de santé (HAS) published recommendations in 2015 and 2020 concerning the conditions of use of LM on the treated and contralateral breast. These appear to be inconsistently followed., Methods: Twelve members of the Senology Commission of the Collège national des gynécologues-obstétriciens français (French College of Gynecologists and Obstetricians) reviewed the carcinological safety of LM and the clinical and radiological follow-up of patients after breast cancer surgery, based on French and international recommendations and a review of the literature. The bibliographic search was conducted via Medline from 2015 to 2022, selecting articles in French and English and applying PRISMA guidelines., Results: A total of 14 studies on the oncological safety of LM, 5 studies on follow-up and 7 guidelines were retained. The 14 studies (6 retrospective, 2 prospective and 6 meta-analyses) had heterogeneous inclusion criteria and variable follow-up, ranging from 38 to 120 months. Most have shown no increased risk of locoregional or distant recurrence after LM. A retrospective case-control study (464 LMs and 3100 controls) showed, in patients who had no recurrence at 80 months, a subsequent reduction in recurrence-free survival after LM in cases of luminal A cancer, highlighting the number of lost to follow-up (more than 2/3 of luminal A cancers). About follow-up after LM, the 5 series showed the high frequency after LM of clinical mass and radiological images (in ¼ of cases), most often corresponding to cytosteatonecrosis. Most of the guidelines highlighted the uncertainties concerning oncological safety of LM, due to the lack of prospective data and long-term follow-up., Discussion and Perspectives: The members of the Senology Commission agree with the conclusions of the HAS working group, in particular by advising against LM "without cautionary periods", excessively, or in cases of high risk of relapse, and recommend clear, detailed information to patients before undergoing LM, and the need for postoperative follow-up. The creation of a national registry could address most questions regarding both the oncological safety of this procedure and the modalities of patient follow-up., (Copyright © 2023 Elsevier Masson SAS.

Objective: Based on an updated review of the international literature covering the different surgical techniques and complications of risk reducing mastectomies (RRM) in non-genetic context, the Commission of Senology (CS) of the College National des Gynécologues Obstétriciens Français (CNGOF) aimed to establish recommendations on the techniques to be chosen and their implementation., Design: The CNGOF CS, composed of 24 experts, developed these recommendations. A policy of declaration and monitoring of links of interest was applied throughout the process of making the recommendations. Similarly, the development of these recommendations did not benefit from any funding from a company marketing a health product. The CS adhered to and followed the AGREE II (Advancing guideline development, reporting and evaluation in healthcare) criteria and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method to assess the quality of the evidence on which the recommendations were based. The potential drawbacks of making recommendations in the presence of poor quality or insufficient evidence were highlighted., Methods: The CS considered 6 questions in 4 thematic areas, focusing on oncologic safety, risk of complications, aesthetic satisfaction and psychological impact, and preoperative modalities., Results: The application of the GRADE method resulted in 7 recommendations, 6 with a high level of evidence (GRADE 1±) and 1 with a low level of evidence (GRADE 2±)., Conclusion: There was significant agreement among the CS members on recommendations for preferred surgical techniques and practical implementation., (Copyright © 2021 Elsevier Masson SAS.

Objective: To determine the value of performing a risk-reducting mastectomy (RRM) in the absence of a deleterious variant of a breast cancer susceptibility gene, in 4 clinical situations at risk of breast cancer., Design: The CNGOF Commission of Senology, composed of 26 experts, developed these recommendations. A policy of declaration and monitoring of links of interest was applied throughout the process of making the recommendations. Similarly, the development of these recommendations did not benefit from any funding from a company marketing a health product. The Commission of Senology adhered to the AGREE II (Advancing guideline development, reporting and evaluation in healthcare) criteria and followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method to assess the quality of the evidence on which the recommendations were based. The potential drawbacks of making recommendations in the presence of poor quality or insufficient evidence were highlighted., Methods: The Commission of Senology considered 8 questions on 4 topics, focusing on histological, familial (no identified genetic abnormality), radiological (of unrecognized cancer), and radiation (history of Hodgkin's disease) risk. For each situation, it was determined whether performing RRM compared with surveillance would decrease the risk of developing breast cancer and/or increase survival., Results: The Commission of Senology synthesis and application of the GRADE method resulted in 11 recommendations, 6 with a high level of evidence (GRADE 1±) and 5 with a low level of evidence (GRADE 2±)., Conclusion: There was significant agreement among the Commission of Senology members on recommendations to improve practice for performing or not performing RRM in the clinical setting., (Copyright © 2021 Elsevier Masson SAS.

Objective: Breast cysts are common, often discovered incidentally or subsequently to pain or palpable mass. The purpose of these recommendations is to describe the sonographic findings for classifying breast cystic lesions, to analyze the value and contribution of various imaging techniques and sampling and to provide a management strategy., Materials and Methods: Literature review conducted by a small group and then reviewed and validated by the group designated by the Collège national des gynécologues et obstétriciens français (CNGOF) to make recommendations for clinical practice for benign breast lesions., Results: Breast cysts are classified in 3 categories: simple cysts, complicated cysts and complex cysts. For simple cysts, after ultrasound, no further imaging is necessary, cytology is to consider only as analgesic. For complicated cysts, a control at 4-6 months is recommended; the use of cytology depends on the context (familial risk, difficulty of follow-up). In case of complex cyst, sampling by cytology or biopsy is recommended. More assessments of other imaging tests are reported., Conclusion: The sonographic characterization is essential for management of breast cyst., (Copyright © 2015 Elsevier Masson SAS.

Background: Large-core needle biopsy of the breast (LCNB) and vacuum-assisted breast biopsy (VABB) are widely used as alternatives to open surgical biopsy (OSB) for initial diagnosis of mammographic abnormalities. Between 18% and 80% of cases in which such specimens show atypical lobular hyperplasia (ALH) or atypical ductal hyperplasia (ADH) are found to be malignant at surgery., Design: From 1999 to 2005, 68 women with mammographic abnormalities were sampled by stereotactic VABB and presented atypical epithelial hyperplasia. Immunohistochemical staining with anti-cytokeratin 5/6 and anti-E-cadherin antibodies was performed. All women underwent a lumpectomy. Clinical, radiological or histological factors predictive of the risk of finding malignancy at surgery were sought., Results: VABB initially showed 28 cases of ADH, 32 cases of ALH, one case of flat epithelial atypia, five cases of mixed atypia, and two cases of Lobular Carcinoma In Situ (LCIS). After slide review with immunohistochemical staining, two cases of ADH were reclassified as simple hyperplasia and two cases of ALH were reclassified as mixed atypia. Seven lesions (10.3%) that appeared to be benign on VABB were found to be malignant on OSB (Ductal Carcinoma In Situ (DCIS) in six cases and invasive ductal carcinoma in one case). ADH was the only predictive factor of malignancy on OSB (p=0.04 versus ALH)., Conclusion: ADH diagnosed by vacuum-assisted breast biopsy frequently corresponds to cancer on open surgical biopsy. Surgical excision of all breast lesions containing atypical hyperplasia on percutaneous biopsy can be recommended., (Copyright (c) 2009 Elsevier Ltd. All rights reserved.)

Interventional imaging permits the logical management of possibly malignant abnormalities, on condition that good guidance techniques and good sampling tools appropriate to the target image are available. Aspiration is a simple and effective technique well suited to abnormalities detected after screening and unlikely to be malignant. Microbiopsy of possibly nodular abnormalities makes it possible to confirm the diagnosis and to improve management strategy. Biopsy by an image-guided minimally invasive aspiration device is an essential tool for management of microcalcifications because it can avoid nearly half of the surgical interventions for benign lesions. For malignancies, it improves the rate of useful surgical biopsy and facilitates an appropriate surgical strategy. Ultrasound-guided biopsy should become increasingly important in breast care, but its indications must be carefully defined.

Unlabelled: The objective of this prospective study of a 115-case series cases was to delineate the specific usefulness of this technique for the diagnosis and management of patients with microcalcifications., Materials and Methods: Patients with probably benign ACRII and III (n = 87) or suspicious ACRIV (n = 14) and high suspicious lesion ACRV (n = 7) lesions. The microcalcification sites were blopsied with a dedicated table and a vacuum assisted aspiration system (Mammotome). The results were correlated either with the results of any surgery or, for the lesions with benign histology findings, with the results of the six-month follow-up mammography., Results: These results concern a series with a follow-up longer than one year. The patients' mean age was 53 years. The procedure was possible in 108 of 115 cases (feasibility). There were two failures. We studied 87 patients with ACRII or III findings; the mean size of the microcalcification cluster was 8.3 +/- 6 mm. For 67, it was less than or equal to 10 mm. The mean size for the 21 patients initially staged as ACRIV or V was 18 +/- 9 mm, and for 15 of them, it was less than or equal to 10 mm. Microcalcifications were found on the radiographs of 96% of the biopsies specimens. Excision was complete in 59 of 73 cases for the clusters less than or equal to 10 mm and in only 12 of 35 cases for the larger clusters. The correlation between the ACR staging and the histology results was excellent., Conclusion: Vacuum-aspirated biopsies are indicated especially among patients with an ACRIII finding and a cluster smaller than 10 mm. Surgery was avoided in more than 60% of these cases. When surgery was performed, it most often resulted in the discovery of malignant lesions. This procedure was also useful for the very small ACRIV clusters, which were totally benign and completely excised. Finally it can be useful for obtaining a preoperative diagnosis in the case of extensive ACRIV or ACRV lesions (strategic biopsies).

We assessed the accuracy with which stereotactic core biopsy of breast microcalcifications helps to justify follow-up or indicate required surgical planning. Eighty-nine patients underwent stereotactic breast biopsy performed with large core needles. Histopathologic findings of microbiopsies were correlated with radiological findings, with follow up and with surgical findings. Agreement between radiological and histopathologic findings on biopsies was obtained in 86% for benign results. Even in the case of benign radiological findings, the histological results of microbiopsies required a surgical biopsy justified in 10% of cases. Radiologically suspicious or malignant microcalcifications were correlated with 35% benign and 65% malignant histologies on biopsies. The positive predictive value, negative predictive value and accuracy were respectively 93%, 86% and 95%. Invasive lesions were found on microbiopsies in 39% of excised malignant lesions. Multifocal lesions were proved on microbiopsies in 50% of all excised carcinomas. Microbiopsies help to disclose malignant lesions undetected on radiological analysis, and may obviate diagnostic surgical biopsy in many cases.

The increase of mammographies has lead to the discovery of more frequent mammary microcalcifications. Presently, about 30% of breast tumors are discovered from infraclinics lesions. Instead of the different classifications, the microcalcifications are the omnious sign with bad specificity. It is in the aim to improve the diagnostic etiology and the choice of therapy, that the directed microbiopsies on microcalcifications had been realized. After an orthogonal location and under local anesthesia, we performed at least six biopsies with a 2.1 mm (14 gauge) needle. This allowed recovery of malignant lesions during the control of microcalcifications and permitted considerable early operative treatment. In fact, a diagnostic and therapeutic advancement of 12 months as compared to a clinical diagnosis, permitting a 30% reduction of metastasis.
