Background There is no consensus on axillary management after neoadjuvant therapy (NAT) in patients with clinically node-positive (cN+) breast cancer. To investigate current clinical practice, an international survey was conducted among breast surgeons and radiation oncologists. The aim of the first part of the survey was to provide a snapshot of international discrepancies regarding axillary surgery in this context. Methods The European Breast Cancer Research Association of Surgical Trialists (EUBREAST) developed a web-based survey containing 39 questions describing clinical scenarios in the setting of axillary management in patients with cN1 disease converting to ycN0 after NAT. The survey was then distributed to breast surgeons and radiation oncologists via 14 breast cancer societies between April and October 2021. Results Responses from 349 physicians in 45 countries were recorded. The most common post-NAT axillary surgery in patients with cN1 disease converting to ycN0 was targeted axillary dissection (54.2 per cent), followed by sentinel lymph node biopsy (SLNB) alone (20.9 per cent), level 1-2 axillary lymph node dissection (ALND) (18.4 per cent), level 1-3 ALND (4 per cent), and targeted lymph node biopsy (2.5 per cent). For SLNB alone, dual tracers were most commonly used (62.3 per cent). Management varied widely in patients with ambiguous axillary status before initiation of treatment or a residual metastatic burden in the axilla after NAT. In patients with ycN+ tumours, ALND was the preferred surgical approach for 66.8 per cent of respondents. Conclusion These results highlight the wide heterogeneity in surgical approaches to the axilla after NAT. To standardize the guidelines, further data from clinical research are urgently needed, which underlines the importance of the ongoing AXSANA (EUBREAST-3) study. Several discrepancies in the surgical approach to the axilla in patients with cN+ disease converting to ycN0 exist. The most common axillary surgical approaches in patients with cN1 tumours converting to ycN0 are targeted axillary dissection (TAD) and sentinel lymph node biopsy. In targeted lymph node biopsy/TAD, there was a wide heterogeneity with regard to localization techniques.

Purpose: To evaluate the feasibility, early toxicity, and clinical outcomes of early-breast cancer patients in a single-arm, phase I/II study of an ultra-accelerated, four-fraction schedule of minimal breast irradiation (4f-AMBI) using a multicatheter, minimally-invasive, intraoperative tumor bed implant (MITBI) during breast-conserving surgery (BCS).
Methods and materials: Eligible women aged >40 years with clinically and radiologically confirmed, unifocal invasive or in situ ¿3 cm tumors were considered as potential candidates for MITBI during BCS. After the pathology report, patients who met APBI criteria received ultra-accelerated four-fractions irradiation (6.2 Gy BID x 4fx over 2 days) with perioperative HDR-brachytherapy (PHDRBT). Early complications, toxicity, clinical outcomes, and cosmetic results were analyzed.
Results: Of 89 patients initially implanted, 60(67.4%) were definitively included in the 4f-AMBI-protocol. The median age was 64.4 years; the median CTV was 32.1 cc (6.9-75.4 cc), and the external-V100 was 43.1 cc (12.87-107 cc), representing 5% of the breast tissue irradiated with a median CTV D90 of 6.2 Gy (5.6-6.28 Gy). The entire local treatment (BCS&MITBI-4f-AMBI) was completed at a median of 8 days (4-10 days). The rate of early complications was 11%. There were no major complications. Acute skin-subcutaneous G1 toxicity was reported in 11.7%, and late G1 toxicity on 36.7%. After a median follow-up of 27 months (11-51 months), the local, elsewhere, locoregional and distant-control rates were 100%, 98.3%, 100%, and 100% respectively. The early-cosmetic evaluation was excellent-good in 94.5% of patients evaluated.
Conclusions: Ultra-accelerated, four-fraction, minimal breast irradiation (4f-AMBI) using a minimally-invasive tumor bed implant procedure is safe, dosimetrically feasible, and shows small irradiated volumes. This program provides low toxicity rates and excellent short-term clinical and cosmesis outcomes.

Introduction Nipple-sparing mastectomy (NSM) with immediate breast reconstruction (IBR) is increasingly used for both breast cancer (TNSM) and risk reduction (RRNSM). The aim of the study is to report the results of the INSPIRE registry assessing health-related quality of life (HRQoL) comparing baseline and 1-year follow-up, regarding surgical indications and chemotherapy (CT) received. Methods INSPIRE is a prospective database including women undergoing NSM and IBR from 18 countries. HRQoL was measured using EORTC QLQC30 and QLQ-BR23 before surgery and after 1 year. Results A total of 677 women were included, of whom 537 (79.3%) underwent TNSM and 140 (21.6%) RRNSM: in total, 806 NSM (556 TNSM and 250 RRNSM). Nipple involvement was present in 7.73% of TNSM and incidental carcinoma in 1.2% of the RRNSM group. Out of the overall 537 patients with systemic treatment, 177 (32.96%) received neoadjuvant chemotherapy (NCT) and 118 (21.92%) adjuvant chemotherapy (CT). A total of 227 patients (28.16%) developed at least one complication postoperatively, 164 (29.5%) in the TNSM group and 63 (25.2%) in the RRNSM group. The TNSM group improved in global health status and emotional functioning after 1 year. No differences were found when comparing HRQoL at 1 year between patients who received NCT and those who received adjuvant CT. The RRNSM group showed improvement in HRQoL, with better emotional functioning and fatigue after 1 year. Conclusions This registry reports HRQoL findings after NSM. The impact of CT on worse HRQoL is independent from its timing. Patients with RRNSM showed an improved HRQoL at 1-year follow-up. Discussion of HRQoL outcomes with patients will facilitate the informed decision-making when considering NSM.

Neoadjuvant treatment (NAT) has become an option in early stage (stage I-II) breast cancer (EBC). New advances in systemic and targeted therapies have increased rates of pathologic complete response increasing the number of patients undergoing NAT. Clear benefits of NAT are downstaging the tumor and the axillary nodes to de-escalate surgery and to evaluate response to treatment. Selection of patients for NAT in EBC rely in several factors that are related to patient characteristics (i.e, age and comorbidities), to tumor histology, to stage at diagnosis and to the potential changes in surgical or adjuvant treatments when NAT is administered. Imaging and histologic confirmation is performed to assess extent of disease y to confirm diagnosis. Besides mammogram and ultrasound, functional breast imaging MRI has been incorporated to better predict treatment response and residual disease. Contrast enhanced mammogram (CEM), shear wave elastography (SWE), or Dynamic Optical Breast Imaging (DOBI) are emerging techniques under investigation for assessment of response to neoadjuvant therapy as well as for predicting response. Surgical plan should be delineated after NAT taking into account baseline characteristics, tumor response and patient desire. In the COVID era, we have witnessed also the increasing use of NAT in patients who may be directed to surgery, unable to have it performed as surgery has been reserved for emergency cases only.

Aim: Demand for nipple-and skin-sparing mastectomy (NSM/SSM) with immediate breast reconstruction (BR) has increased at the same time as indications for post-mastectomy radiation therapy (PMRT) have broadened. The aim of the Oncoplastic Breast Consortium initiative was to address relevant questions arising with this clinically challenging scenario. Methods: A large global panel of oncologic, oncoplastic and reconstructive breast surgeons, patient advocates and radiation oncologists developed recommendations for clinical practice in an iterative process based on the principles of Delphi methodology. Results: The panel agreed that surgical technique for NSM/SSM should not be formally modified when PMRT is planned with preference for autologous over implant-based BR due to lower risk of long-term complications and support for immediate and delayed-immediate reconstructive approaches. Nevertheless, it was strongly believed that PMRT is not an absolute contraindication for implant-based or other types of BR, but no specific recom-mendations regarding implant positioning, use of mesh or timing were made due to absence of high-quality evidence. The panel endorsed use of patient-reported outcomes in clinical practice. It was acknowledged that the shape and size of reconstructed breasts can hinder radiotherapy planning and attention to details of PMRT techniques is important in determining aesthetic outcomes after immediate BR. Conclusions: The panel endorsed the need for prospective, ideally randomised phase III studies and for surgical and radiation oncology teams to work together for determination of optimal sequencing and techniques for PMRT for each patient in the context of BR

Aims: We analysed the impact of the SARS-CoV-2 pandemic (COVID-19) on the quality of breast cancer care in certified EUSOMA (European Society of Breast Cancer Spe-cialists) breast centres.Materials and methods: The results of the EUSOMA quality indicators were compared, based on pseudonymised individual records, for the periods 1 March 2020 till 30 June 2020 (first COVID-19 peak in most countries in Europe) and 1 March 2019 till 30 June 2019. In addition, a questionnaire was sent to the participating Centres for investigating the impact of the COVID-19 pandemic on the organisation and the quality of breast cancer care.Results: Forty-five centres provided data and 31 (67%) responded to the questionnaire. The total number of new cases dropped by 19% and there was a small significant higher tumour (p = 0.003) and lymph node (p = 0.011) stage at presentation. Comparing quality indicators (12,736 patients) by multivariable analysis showed mostly non-significant differences. Surgery could be performed in a COVID-free zone in 94% of the centres, COVID testing was per-formed before surgery in 96% of the centres, and surgical case load was reduced in 55% of the centres. Modifications of the indications for neoadjuvant endocrine therapy, chemo-therapy, and targeted therapy were necessary in 23%, 23%, and 10% of the centres; changes in indications for adjuvant endocrine, chemo-, targeted, immune, and radiotherapy in 3%, 19%, 3%, 6%, and 10%, respectively.Conclusion: Quality of breast cancer care was well maintained in EUSOMA breast centres during the first wave of the COVID-19 pandemic. A small but significantly higher tumour and lymph node stage at presentation was observed. 2022 Elsevier Ltd. All rights reserved.

Background The MINDACT trial showed excellent 5-year distant metastasis-free survival of 94.7% (95% CI 92.5-96.2) in patients with breast cancer of high clinical and low genomic risk who did not receive chemotherapy. We present long-term follow-up results together with an exploratory analysis by age. Methods MINDACT was a multicentre, randomised, phase 3 trial done in 112 academic and community hospitals in nine European countries. Patients aged 18-70 years, with histologically confirmed primary invasive breast cancer (stage T1, T2, or operable T3) with up to three positive lymph nodes, no distant metastases, and a WHO performance status of 0-1 were enrolled and their genomic risk (using the MammaPrint 70-gene signature) and clinical risk (using a modified version of Adjuvant! Online) were determined. Patients with low clinical and low genomic risk results did not receive chemotherapy, and patients with high clinical and high genomic risk did receive chemotherapy (mostly anthracycline-based or taxane-based, or a combination thereof). Patients with discordant risk results (ie, patients with high clinical risk but low genomic risk, and those with low clinical risk but high genomic risk) were randomly assigned (1:1) to receive chemotherapy or not based on either the clinical risk or the genomic risk. Randomisation was done centrally and used a minimisation technique that was stratified by institution, risk group, and clinical-pathological characteristics. Treatment allocation was not masked. The primary endpoint was to test whether the distant metastasis-free survival rate at 5 years in patients with high clinical risk and low genomic risk not receiving chemotherapy had a lower boundary of the 95% CI above the predefined non-inferiority boundary of 92%. In the primary test population of patients with high clinical risk and low genomic risk who adhered to the treatment allocation of no chemotherapy and had no change in risk post-enrolment. Here, we present updated follow-up as well as an exploratory analysis of a potential age effect (<= 50 years vs >50 years) and an analysis by nodal status for patients with hormone receptor-positive and HER2-negative disease. These analyses were done in the intention-to-treat population. This study is registered with ClinicalTrials.gov, NCT00433589, and the European Clinical Trials database, EudraCT2005-002625-31. Recruitment is complete and further long-term follow-up is ongoing. Findings Between Feb 8, 2007, and July 11, 2011, 6693 patients were enrolled. On Feb 26, 2020, median follow-up was 8.7 years (IQR 7.8-9.7). The updated 5-year distant metastasis-free survival rate for patients with high clinical risk and low genomic risk receiving no chemotherapy (primary test population, n=644) was 95.1% (95% CI 93.1-96.6), which is above the predefined non-inferiority boundary of 92%, supporting the previous analysis and proving MINDACT as a positive de-escalation trial. Patients with high clinical risk and low genomic risk were randomly assigned to receive chemotherapy (n=749) or not (n=748); this was the intention-to-treat population. The 8-year estimates for distant metastasis-free survival in the intention-to-treat population were 92.0% (95% CI 89.6-93.8) for chemotherapy versus 89.4% (86.8-91.5) for no chemotherapy (hazard ratio 0.66; 95% CI 0.48-0.92). An exploratory analysis confined to the subset of patients with hormone receptor-positive, HER2-negative disease (1358 [90.7%] of 1497 randomly assigned patients, of whom 676 received chemotherapy and 682 did not) shows different effects of chemotherapy administration on 8-year distant metastasis-free survival according to age: 93.6% (95% CI 89.3-96.3) with chemotherapy versus 88.6% (83.5-92.3) without chemotherapy in 464 women aged 50 years or younger (absolute difference 5.0 percentage points [SE 2.8, 95% CI -0.5 to 10.4]) and 90.2% (86.8-92.7) versus 90.0% (86.6-92.6) in 894 women older than 50 years (absolute difference 0.2 percentage points [2.1, -4.0 to 4.4]). The 8-year distant metastasis-free survival in the exploratory analysis by nodal status in these patients was 91.7% (95% CI 88.1-94.3) with chemotherapy and 89.2% (85.2-92.2) without chemotherapy in 699 node-negative patients (absolute difference 2.5 percentage points [SE 2.3, 95% CI -2.1 to 7.2]) and 91.2% (87.2-94.0) versus 89.9% (85.8-92.8) for 658 patients with one to three positive nodes (absolute difference 1.3 percentage points [2.4, -3.5 to 6.1]). Interpretation With a more mature follow-up approaching 9 years, the 70-gene signature shows an intact ability of identifying among women with high clinical risk, a subgroup, namely patients with a low genomic risk, with an excellent distant metastasis-free survival when treated with endocrine therapy alone. For these women the magnitude of the benefit from adding chemotherapy to endocrine therapy remains small (2.6 percentage points) and is not enhanced by nodal positivity. However, in an underpowered exploratory analysis this benefit appears to be age-dependent, as it is only seen in women younger than 50 years where it reaches a clinically relevant threshold of 5 percentage points. Although, possibly due to chemotherapy-induced ovarian function suppression, it should be part of informed, shared decision making. Further study is needed in younger women, who might need reinforced endocrine therapy to forego chemotherapy. Copyright (C) 2021 Esevier Ltd. All rights reserved.

Introduction Breast conservative surgery (BCS) and sentinel lymph node biopsy (SLNB) after neoadjuvant treatment (NAT) is safe and effective for selected patients. This aim of this study is to evaluate the impact of anatomic site of response on outcomes and to assess the real population who may benefit from nonsurgical approaches after NAT. Material and Methods From a prospectively maintained database, patients with T1-4 N0-2 breast cancer undergoing NAT were identified. Clinicopathological and survival rates were compared in relation to response and anatomic site of response. Results Six hundred and forty-six patients were included in the study. Pathologic complete response (pCR) was an independent factor for BCS and SLN. HER2 positive and TN tumors with cN0 achieving a breast pCR remain ypN0 (p = .002). Residual axillary disease was associated with breast residual tumor (p = .05) and subtype (p = .001). With a median follow up of 35.25 months, patients with any pCR had improved survival when compared with partial response, but not significant differences between pCR, axillary pCR, or breast pCR. Conclusion Achieving a pCR increases BCS and SLN. In selected subgroups, sparing any axillary surgery after NAT maybe feasible. In cN+ patients, any pCR was associated with survival, but not the anatomic site of response.

Introduction: The non-radioactive method that uses the magnetic tracer (SPIO/Sienna) has shown to be a feasible technique for the SLN detection in breast cancer patients. The aim of this study is to assess the efficacy of different doses of a new magnetic tracer Sienna XP (Magtrace) compared to Tc-99 m and to evaluate its non-inferiority. Methods: Patients diagnosed with early-stage breast cancer cT1-3 N0, from October 2016 to August 2018 were eligible and consecutively randomized to three different doses of new SPIO used: group 1 (1 mL), group 2 (1.5 mL) and group 3 (2 mL). Results: A total of 135 patients were included in the study, 45 in each group. Detection of SLNs with the three doses of Sienna XP (1 mL, 1.5 mL and 2 mL) showed non-inferior rates compared to the conventional technique with radiotracer (p = 0.654). Concordance by patients with SLN positive was 100% for all groups. 83 (70.3%) patients reported skin staining at one month postoperatively, significantly lower in group 1 (p = 0.042). At 6 months follow up, group 1 remains with significantly lower skin discoloration (p = 0,01). In multivariate analysis, dose of 2 mL showed statistically significant for the skin staining. The majority of patients (70%) felt that skin discoloration does not represent a problem. Conclusion: The use of the Sienna XP magnetic tracer at 1 mL is not inferior to higher doses of magnetic tracer neither is inferior to radiotracer. 1 mL of magnetic tracer resulted in significantly less skin discoloration compared to higher doses.

Introduction: Axillary staging (pN) is a strong predictor of outcome in early stage breast cancer yet following the publication of the Z0011 trial there has been an increasing tendency to spare lymph node dissection. Automated molecular detection of cytokeratin 19mRNA by one-step nucleic acid amplification (OSNA) has been demon-strated to be an accurate method to assess sentinel lymph node (SLN) metastasis. In this study we compare histological and molecular methods following complete axillary lymph node dissection (cALND), determine whether molecular axillary staging affects survival, and evaluate the predictive and prognostic value of total tumor load in ALND (AD-TTL) and in all positive nodes (G-TTL). Material and methods: Axillary lymph nodes were collected from 102 patients with primary breast cancer with histological confirmation of axillary involvement (cN+) or positive SLN. The central 1-mm portion of each nonSLN was processed for hematoxylin-eosin staining and the remaining tissue was analyzed by OSNA. Results: Non-SLNs were diagnosed as positive in 72 out of 102 patients (70.6 %) on OSNA compared with only 53 (52 %) on histology (p < 0.01). Thirteen patients would have changed staging if the diagnoses provided had been by molecular methods (p < 0.01), but without a change in prognosis. AD-TTL and G-TTL were predictive of recurrence and mortality. Conclusions: Compared to molecular detection, histological examination significantly underestimates the frequency of axillary node metastases. However, the increase in pN did not show a clinical effect on survival in those patients.

Breast cancer is the cancer with the most incidence and mortality in women. microRNAs are emerging as novel prognosis/diagnostic tools. Our aim was to identify a serum microRNA signature useful to predict cancer development. We focused on studying the expression levels of 30 microRNAs in the serum of 96 breast cancer patients vs. 92 control individuals. Bioinformatic studies provide a microRNA signature, designated as a predictor, based on the expression levels of five microRNAs. Then, we tested the predictor in a group of 60 randomly chosen women. Lastly, a proteomic study unveiled the overexpression and downregulation of proteins differently expressed in the serum of breast cancer patients vs. that of control individuals. Twenty-six microRNAs differentiate cancer tissue from healthy tissue, and 16 microRNAs differentiate the serum of cancer patients from that of the control group. The tissue expression of miR-99a, miR-497, miR-362, and miR-1274, and the serum levels of miR-141 correlated with patient survival. Moreover, the predictor consisting of miR-125b, miR-29c, miR-16, miR-1260, and miR-451 was able to differentiate breast cancer patients from controls. The predictor was validated in 20 new cases of breast cancer patients and tested in 60 volunteer women, assigning 11 out of 60 women to the cancer group. An association of low levels of miR-16 with a high content of CD44 protein in serum was found. Circulating microRNAs in serum can represent biomarkers for cancer prediction. Their clinical relevance and the potential use of the predictor here described are discussed.

Purpose: To evaluate our institutional experience of minimally invasive tumor bed implantation (MITBI) during breast-conserving surgery (BCS) for ductal carcinoma in situ (DCIS) to deliver peri-operative high-dose-rate brachytherapy (PHDRBT) as accelerated minimal breast irradiation (AMBI) or anticipated boost (A-PHDRBT-boost).
Material and methods: Patients older than 40, with clinical and radiological unifocal DCIS < 3 cm were considered potential candidates for accelerated partial breast irradiation (APBI) and were implanted during BCS using MITBI-technique. Patients who in final pathology reports showed free margins and no other microscopic tumor foci, received AMBI with PHDRBT (3.4 Gy BID in 5 days). Patients with adverse features received A-PHDRBT-boost with post-operative external beam radiotherapy (EBRT).
Results: Forty-one patients were implanted, and 36 were treated and analyzed. According to final pathology, 24 (67%) patients were suitable for AMBI and 12 (33%) were qualified for A-PHDRBT-boost. Reoperation rate for those with clear margins was 16.6% (6/36); this rate increased to 33% (4/12) for G3 histology, and 66% (4/6) were rescued using AMBI. Early complications were documented in 5 patients (14%). With a median follow-up of 97 (range, 42-138) months, 5-year rates of local, elsewhere, locoregional, and distant control were all 97.2%. 5-year ipsilateral breast tumor recurrence rates (IBTR) were 5.6% (2/36), 8.3% (2/24) for AMBI, and 0% (0/12) for A-PHDRBT-boost patients. Both instances of IBTR were confirmed G3 tumors in pre-operative biopsies; no IBTR was documented in G1-2 tumors. Cosmetic outcomes were excellent/good in 96% of AMBI vs. 67% in A-PHDRBT-boost (p = 0.034).
Conclusions: The MITBI-PHDRBT program allows selection of patients with excellent prognoses (G1-2 DCIS with negative margins and no multifocality), for whom AMBI could be a good alternative with low recurrence rate, decrease of unnecessary radiation, treatment logistics improvement, and over-treatment reduction. Patients whose pre-operative biopsy showed G3 tumor, presents with inferior local control and more risk of reoperation due to positive margins.

The onset of the COVID-19 pandemic has changed the face of the treatment of breast cancer and breast reconstruction globally. Mastectomy with immediate implant-based breast reconstruction was on the rise due to advances in meshes and implants. However, due to the prioritisation of the critically ill and diversion of the work force, breast cancer treatment has drastically changed. This is an opinion paper written by the authors with experience and importance in the scenario of breast reconstructive surgery. The authors are from different countries with the COVID-19 pandemic in different stages.

This article is an update of the requirements of a specialist breast centre, produced by EUSOMA and endorsed by ECCO as part of Essential Requirements for Quality Cancer Care (ERQCC) programme, and ESMO. To meet aspirations for comprehensive cancer control, healthcare organisations must consider the requirements in this article, paying particular attention to multidisciplinarity and patient-centred pathways from diagnosis, to treatment, to survivorship. The centrepiece of this article is the requirements section, comprising definitions; multidisciplinary structure; minimum case, procedure and staffing volumes; and detailed descriptions of the skills of, and resources needed by, members and specialisms in the multidisciplinary team in a breast centre. These requirements are positioned within narrative on European breast cancer epidemiology, the standard of care, challenges to delivering this standard, and supporting evidence, to enable a broad audience to appreciate the importance of establishing these requirements in specialist breast centres.

As part of its mission to promote the best surgical care for cancer patients, the European Society of Surgical Oncology (ESSO) has been developing multiple programmes for clinical research along with its educational portfolio. This position paper describes the different research activities of the Society over the past decade and an action plan for the upcoming five years to lead innovative and high quality surgical oncology research. ESSO proposes to consider pragmatic research methodologies as a complement to randomised clinical trials (RCT), advocates for increased funding and operational support in conducting research and aims to enable young surgeons to be active in research and establish partnerships for translational research activities.

Background: Intraoperative ultrasound guided surgery (IOUS) is an effective surgical technique for breast cancer with advantages over wire localization guided surgery (WL), enabling smaller lumpectomies without compromising margins. Nevertheless, it has had a slow implementation, maybe due to lacking a learning curve. Also differences in costs are not clearly reported. The aim of the study is to assess differences in volume of healthy breast tissue excised, to establish a learning curve and to prove it is cost saving. Patients and methods: From February 2009 to April 2013, women diagnosed with invasive breast cancer eligible for IOUS or WL breast conserving surgery were recorded into a prospectively maintained database. Both groups were compared for differences in margin status, second surgeries and excess of healthy tissue resected, defined by the calculated resection ratio (CRR). A raw cost study was assessed. IOUS learning curve was analyzed using Cumulative sum control chart (CUSUM). Results: The study included 214 patients, 148 (69.16%) in the IOUS group and 66 (30.84%) in the WL group. IOUS showed significantly smaller surgical volumes (p = 0.02), smaller CRR (p = 0.006), higher rate of negative margins (p = 0.017) and less surgical time (p = 0.006) than WL. Learning curves based on complete tumor excision and no need for second surgeries showed that 11 cases were enough to master the technique. Around 900(sic) per surgery was saved using IOUS vs. WL. Conclusion: IOUS decreases excision of healthy breast tissue while increasing negative margin rates compared to WL. IOUS can be easily implemented; 11 cases are enough to acquire skills for performing the technique. Savings can be up to 900(sic) per surgery.

Objective: To evaluate the efficacy and learning curve of ultrasoundguided vacuum-assisted excision (US-VAE) of benign breast lesions, and to assess characteristics associated with residual lesion. Methods: This was a retrospective study with institutional review board-approval. Sonographic and clinical follow-up were performed 6 months after intervention. Effectiveness and safety of the technique were analyzed. The cumulative summation (CUSUM) graphs were used to evaluate learning curves concerning complete excision and hematoma. Results: 152 ultrasound-VAEs in 143 patients were included. Initial complete resection was achieved in 90.8 % (138 of 152). 6-month follow-up was completed for 143 (94%) of cases and complete resection was observed in 72 % (100 of 143). Mean maximum size without residual tumor was 16.9 mm, while with residual lesion it was 21.9 mm (p = < 0.001), with a volume of 1.53 and 3.39 cm(3), respectively (p = < 0.001). Increase in lesion size and volume was associated with less effectiveness (p = 0.05), clinical control (p = 0.05), and higher risk of clinically significant hematoma (p = 0.05). Receiver operating characteristic analysis demonstrate a volume threshold of 2.6 cm(3) (r = 0.71, specificity 84.5%) for leaving no residual lesion. Cumulative summation graphs demonstrate that, on average, 11 excisions were required to acquire skills to perform complete excision in more than 80% at the end of the ultrasound-VAE and 18 excisions at 6 months. Conclusion: Ultrasound-VAE is an effective treatment for benign breast lesions. Breast lesion volume should be considered when assessing for percutaneous treatment. Advances in knowledge: A follow-up of the learning process of ultrasound-VAE will be a valuable tool to assess the efectiveness and safety of the technique i

With the European Parliament elections having taken place in May 2019 and a new European Commission (EC) taking office in November 2019, this year is critical for European policymakers, as goals and priorities of the European Union (EU) for the next five years will be discussed and agreed upon.
This Manifesto issued by the Transforming Breast Cancer Together initiative calls upon policymakers to improve services for patients in an area still of high unmet need and reduce the societal impact of breast cancer by elevating it as a health policy priority to improve breast cancer prevention, diagnosis and care across Europe.

Preoperative systemic therapy (PST) has become an accepted treatment not only for locally advanced but also for early stage breast cancer patients. Clinical trials have demonstrated that the use of PST is equally to adjuvant treatments in terms of overall survival, and has the advantage of increasing rates of breast conservative surgery and rates of pathologic complete response, a surrogate endpoint for the effectiveness of systemic therapy. Initial studies have suggested higher rates of locoregional recurrence with this approach. However, the optimization of systemic and targeted therapy and the multidisciplinary care is key to achieving optimal outcomes in this setting. (C) 2018 Published by Elsevier Ltd.
