ABSTRACT

BACKGROUND: The necessity of performing a sentinel lymph node biopsy in patients with clinically and radiologically node-negative breast cancer after neoadjuvant chemotherapy has been questioned. The aim of this study was to determine the rate of nodal positivity in these patients and to identify clinicopathological features associated with lymph node metastasis after neoadjuvant chemotherapy (ypN+). METHODS: A retrospective multicentre study was performed. Patients with cT1-3 cN0 breast cancer who underwent sentinel lymph node biopsy after neoadjuvant chemotherapy between 2016 and 2021 were included. Negative nodal status was defined as the absence of palpable lymph nodes, and the absence of suspicious nodes on axillary ultrasonography, or the absence of tumour cells on axillary nodal fine needle aspiration or core biopsy. RESULTS: A total of 371 patients were analysed. Overall, 47 patients (12.7%) had a positive sentinel lymph node biopsy. Nodal positivity was identified in 22 patients (29.0%) with hormone receptor+/human epidermal growth factor receptor 2- tumours, 12 patients (13.8%) with hormone receptor+/human epidermal growth factor receptor 2+ tumours, 3 patients (5.6%) with hormone receptor-/human epidermal growth factor receptor 2+ tumours, and 10 patients (6.5%) with triple-negative breast cancer. Multivariable logistic regression analysis showed that multicentric disease was associated with a higher likelihood of ypN+ (OR 2.66, 95% c.i. 1.18 to 6.01; P = 0.018), whilst a radiological complete response in the breast was associated with a reduced likelihood of ypN+ (OR 0.10, 95% c.i. 0.02 to 0.42; P = 0.002), regardless of molecular subtype. Only 3% of patients who had a radiological complete response in the breast were ypN+. The majority of patients (85%) with a positive sentinel node proceeded to axillary lymph node dissection and 93% had N1 disease. CONCLUSION: The rate of sentinel lymph node positivity in patients who achieve a radiological complete response in the breast is exceptionally low for all molecular subtypes.

ABSTRACT

Nipple-sparing mastectomy is an alternative to skin-sparing mastectomy in select patients. Increasing evidence supports its use in the setting of breast cancer, however concerns still exist regarding oncological safety. The aim of this systematic review was to evaluate long-term oncological outcomes of patients who underwent nipple-sparing mastectomy for breast cancer. A systematic review of the literature was performed to evaluate oncological outcomes in patients with breast cancer who underwent nipple-sparing mastectomy. Five major databases (PubMed, Embase, Scopus, Web of Science and Cochrane) were searched. The review included all original articles published in English reporting long-term oncological outcomes. 2334 studies were identified. After applying inclusion and exclusion criteria, 17 retrospective studies involving 7107 patients were included. The indication for nipple-sparing mastectomy was invasive carcinoma in 6069 patients (85.4%) and in situ disease in 1038 (14.6%). Median follow up was 48 months (range 25-94). The weighted mean rates of local recurrence and recurrence involving the nipple-areola complex were 5.4% (0.9-11.9) and 1.3% (0-4.9), respectively. The weighted mean distant failure rate was 4.8% (1.5-23.0). Therapeutic nipple-sparing mastectomy is oncologically safe in select patients with breast cancer.

ABSTRACT

BACKGROUND: The Clinical Treatment Score post-5 years (CTS5) integrates four clinicopathological variables to estimate the residual disease recurrence risk in hormone receptor-positive breast cancer patients who have been treated with five years of adjuvant endocrine therapy. This study aimed to determine the accuracy of the CTS5. METHODS: A systematic review was performed in accordance with the PRISMA statement. Studies relevant for inclusion in the current review were identified from The Cochrane Library, EBSCO, Ovid, PubMed, and Embase. RESULTS: Six papers reported on 30 354 postmenopausal patients (age range 42 to 91 years). The pooled hazard ratio (HR) of distant recurrence relative to the low-risk CTS5 category was 5.41 (95% c.i. 4.50 to 6.51; P < 0.05) for the high-risk CTS5 category and 2.32 (95% c.i. 1.90-2.84; P < 0.05) for the intermediate CTS5 category. Three papers reported on 10 425 premenopausal patients (age range 18 to 54 years). The pooled HR of distant recurrence relative to the low-risk CTS5 category was 5.42 (95% c.i. 2.26 to 13.01; P < 0.05) for the high-risk CTS5 category and 2.82 (95% c.i. 1.35 to 5.88; P < 0.05) for the intermediate CTS5 category. Relative to high-risk postmenopausal patients, the mean observed 10-year distant recurrence risk for the high CTS5 category was 13.83 per cent, which differs significantly from the CTS5 estimation of 10-year distant recurrence risk (20.3 per cent, 95% c.i. 17.2 to 24; P = 0.000). CONCLUSION: The CTS5 can predict late distant recurrence risk in pre- and postmenopausal hormone receptor-positive breast cancer patients. CTS5 overestimates the risk for high-risk patients and thus, its use in these patients warrants caution.

ABSTRACT

Axillary nodal status remains an important determinant of prognosis and of the therapeutic strategy in patients with a newly diagnosed breast cancer. The aim of this study was to assess the false-negative rate of ultrasound (US)-guided fine-needle aspiration cytology (FNAC) in axillary node staging at breast cancer diagnosis. All patients with a newly diagnosed breast cancer who had an indeterminate or suspicious axillary node sampled with an FNAC between 2007 and 2014 were included in the study. FNAC results were compared to the final histopathological results of surgically removed axillary lymph nodes. Patient demographics, tumor, and nodal characteristics were analyzed. Diagnostic accuracy tests were performed using IBM SPSS, version 22. A total of 3515 patients with breast cancer were identified, 675 of whom had ultrasound-guided FNAC of ipsilateral axillary lymph nodes (mean age: 55 years; Range: 26-84). A benign (C2) result was observed in 52% (n = 351) and a malignant (C5) result in 35% (n = 238). C1 was obtained in 11% (n = 76), C3 in 0.6% (n = 4), and C4 in 0.9% (n = 6). Of the 238 patients with a malignant (C5) FNAC, 99.6% had confirmed axillary lymph node metastatic disease on histopathology. Of the 351 patients with benign FNAC (C2), 31% (n = 108) of patients had a positive lymph node on histology. The false-negative rate of preoperative FNAC remains too high (31%) to omit definitive surgical staging of the axilla. The high diagnostic accuracy when a positive FNAC is obtained allows appropriate tailored decisions regarding definitive therapy.

ABSTRACT

BACKGROUND: The optimal timing of (neo)adjuvant trastuzumab initiation with respect to chemotherapy and surgery remains undefined. METHODS: Retrospective analysis of a large institutional database of HER2-positive patients who received anti-HER2 therapy. We included all Stage I to III patients treated with trastuzumab with a minimum follow up of 3 years. The date of first breast biopsy was recorded as initial diagnosis. RESULTS: A total of 506 patients [adjuvant: 386 (76%)-neo-adjuvant: 120 (24%)] were included. The median time-to-first-trastuzumab (TFT) from diagnosis was 12 weeks (range 1.9-122.3). Median follow-up is 73.3 months (range 1.4-176.3). TFT was significantly shorter in the neo-adjuvant than in the adjuvant cohort (median: 4.4 vs. 14 weeks, p < 0.00001). Despite the neo-adjuvant cohort having significantly more node-positive patients (75 vs. 53%, p < 0.0001), DFS rate (neo-adjuvant: 12.5 vs. adjuvant: 18%, p = 0.094) was numerically superior in neo-adjuvant patients. A TFT ≤ 12 weeks was associated with significantly superior DFS and OS over TFT > 12 weeks. Early concomitant regimens were associated with superior DFS over delayed-concomitant and sequential regimens. CONCLUSIONS: Initiating trastuzumab more than 12 weeks from diagnosis has a negative impact on clinical outcome. Neo-adjuvant anti-HER2 therapy could be the optimal strategy to treat early stage HER2-positive breast cancer.

ABSTRACT

BACKGROUND: Sentinel lymph node biopsy (SLNB) has become the gold standard for axillary staging. Debate remains as to the optimal method of SLN detection. OBJECTIVES: Determine whether patients undergoing an SLNB required the addition of isosulfan blue dye to radioisotope when an SLN was identified on a preoperative lymphoscintigram. METHODS: A prospective randomized controlled trial comparing the combination of radioisotope and blue dye versus radioisotope alone was performed between March 2010 and September 2012. The trial protocol was registered with Current Controlled Trials. Women with clinically and radiologically node-negative breast cancer with a positive preoperative lymphoscintigram were eligible for inclusion. RESULTS: A total of 667 patients were included in the analysis with 342 patients receiving the combination (blue dye and radioisotope) and 325 patients receiving radioisotope alone. The groups were evenly matched both demographically and pathologically. The mean age was 48 years (48.3 vs 47.7 years; P = 0.47), the mean tumour size was 24.2 mm (24.3 mm vs 24.1 mm; P = 0.7) and there was no statistically significant difference in the grade of the tumors between the 2 groups (P = 0.58). There was no difference in the identification rate, nor was that in the number of nodes retrieved between the 2 groups (P = 0.30). There was no difference in the number of positive lymph nodes that were identified between the 2 groups (23.8% vs 22.1%; P = 0.64). CONCLUSIONS: This study failed to demonstrate an advantage with the addition of isosulfan blue dye to radioisotope in the identification of the SLN in the presence of a positive preoperative lymphoscintigram.

ABSTRACT

Background: This study, using real-world data, assesses the impact of RS testing on treatment pathways and the associated economic consequences of such testing. This paper pertains to lobular breast cancer. Methods: A retrospective, observational study was undertaken between 2011 and 2019 on a cross-section of hormone receptor-positive (HR+), HER2-negative, lymph node-negative, early-stage breast cancer patients. All patients had ILC and had RS testing in Ireland. The patient population is representative of the national population. Patients were classified as low (RS ≤ 25) or high (RS > 25) risk. Patients aged ≤50 were stratified as low (RS 0-15), intermediate (RS 16-25), or high risk (RS > 25). Results: A total of 168 patients were included, most of whom had grade 2 (G2) tumors (n = 154, 92%). Overall, 155 patients (92.3%) had low RS (≤25), 12 (7.1%) had high RS (>25), and 1 (0.6%) had unknown RS status. In 29 (17.5%) patients aged ≤50 at diagnosis, RS was ≤15 in 16 (55%), 16-20 in 6 (21%), 21-25 in 5 (17%), >25 in 1 (3.5%), and unknown in 1 (3.5%). Post RS testing, 126 patients (78%) had a change in chemotherapy recommendation; all to hormone therapy. In total, only 35 patients (22%) received chemotherapy. RS testing achieved a 75% reduction in chemotherapy use, resulting in savings of €921,543.84 in treatment costs, and net savings of €387,283.84. Conclusions: The use of this test resulted in a 75% reduction in chemotherapy and a significant cost savings in our publicly funded health system.

ABSTRACT

BACKGROUND: Pathological complete response (pCR) following neo-adjuvant chemotherapy (NACT) for breast cancer is associated with improved disease-free and overall survival in certain breast cancer subtypes. Magnetic Resonance Imaging (MRI) is increasingly used as standard to assess treatment response in patients receiving NACT. The aim of this study was to determine the clinical utility of MRI in accurately predicting pCR post-NACT. METHODS: A single-centre, retrospective study was conducted in breast cancer patients, who received NACT between 2013 and 2020. Patients who had an MRI before and after NACT were included. Pathological and MRI radiological response rates to NACT were analyzed and MRI accuracy assessed in detecting pCR according to breast cancer subtype. RESULTS: One hundred and sixty-seven patients were included in the study. Forty-one of the 167 patients achieved pCR (24.6 %), with the highest proportion in HR- HER2+ subgroup (58.3 %), followed by triple negative breast cancer (TNBC) (35 %). Only 22.2 % and 10.5 % of patients with HR + HER2+ and HR + HER2-respectively achieved pCR. The overall accuracy of MRI in predicting pCR after NACT was 77.3 %. The greatest accuracy was in TNBC (87.5 %) with a specificity and positive predictive value (PPV) of 100 % and the highest number of correctly diagnosed complete responses (14 of 40). MRI was less accurate in predicting response rates in HR + HER2- (PPV 91.2 %) and HR + HER2+ groups (PPV 90.5 %). MRI performed significantly better in predicting complete response in TNBC compared to HR + HER2-subtype (p = 0.0057). CONCLUSION: MRI is a clinically useful adjunct in assessing pCR following NACT and appears to predict pathological response more accurately in TNBC compared to HR + HER2-breast cancer subtypes. This has significant clinical implications in terms of surgical planning, adjuvant treatment options and prognosis.

ABSTRACT

The objective of this study was to make an assessment of the utility of fine needle aspiration cytology (FNAC), in a "one-stop" symptomatic breast triple assessment clinic. Controversy surrounds the optimal tissue biopsy methodology in the diagnosis of symptomatic breast cancer and the identification of benign disease. FNAC in the context of a Rapid Assessment Breast Clinic (RABC) allows the same day diagnosis and early treatment of breast cancer, with the immediate reassurance and discharge of those with benign disease. We analyzed prospective data accrued at a RABC, over a 4-year period from 2004 to 2007. All patients were triple assessed, with FNACs performed on site by two consultant cytopathologists. Investigations were reported immediately, and clinical data were captured via a database using compulsory data field entry. There were 4487 attendances at our RABC, with 1572 FNACs were performed. The positive predictive value of FNAC with a C5 cancer diagnosis was 100%, 95.6% for a C4 report, with a complete sensitivity of 94%. The full specificity of correctly identified benign lesions was 77.4%, with a false negative rate of 3.85%. This enabled 66% of patients attending the RABC to receive a same day diagnosis of benign disease and discharge. FNAC is highly accurate in the diagnosis of symptomatic breast cancer in an RABC. FNAC allows accurate diagnosis of benign disease and immediate discharge of the majority of patients. In this era, when a large majority of patients have benign disease, we believe that FNAC provides an equivalent, if not better, method of evaluation of patients in a triple assessment RABC.

ABSTRACT

BACKGROUND: The significance of exogenous hormone manipulation as part of fertility treatment and its relationship to the development of breast cancer remains uncertain. Several historical reviews have been performed with conflicting results. This study is an updated meta-analysis to determine whether there is a causal relationship between different fertility treatments and breast cancer. METHODS: The study report is based on the guidelines of PRISMA and Meta-Analysis of Observational Studies in Epidemiology. Studies published within the last 20 years were included to reflect up to date in vitro fertilization (IVF) practice. This study was prospectively registered on PROSPERO on 07/04/2021, registration identification CRD42021247706. The primary outcome of the study was to determine whether there is an increased incidence of breast cancer in women treated with hormonal fertility treatment. The secondary outcomes were to determine whether fertility treatments were individually associated with excess breast-cancer risk. RESULTS: Overall, 25 studies, including 617 479 participants, were eligible for inclusion. There was no significant breast-cancer risk association with fertility treatment (compared with general and subfertility reference groups). Summary odds ratio of all included studies was 0.97 (95 per cent c.i. 0.90 to 1.04). Women who received six or more IVF cycles did not have an increased risk of breast cancer. Similarly, there was no excess breast-cancer risk associated with clomiphene, human chorionic gonadotropin, gonadotropin analogues and progesterone when examined individually. Comparably, there was no significant association between fertility treatment and excess breast-cancer risk in patients with more than 10 years' follow-up. Summary odds ratio was 0.97 (95 per cent c.i. 0.85 to 1.12). CONCLUSION: This meta-analysis did not find a significant association between fertility treatments and excess breast-cancer risk. Women considering IVF should be informed that it does not appear to increase breast-cancer risk.

ABSTRACT

The association between immediate breast reconstruction (IBR)-related wound complications and breast cancer recurrence (BCR) remains uncertain. This study aimed to investigate the oncological outcomes in patients with wound complications following mastectomy and IBR. A comprehensive search was undertaken for all studies describing complications in patients with breast cancer following IBR. Studies were included if they reported on complications and investigated their relationship with BCR. A meta-analysis was performed using a random-effects model, with data presented as odds ratios and 95% confidence intervals. A total of 1418 patients from five studies were included in the final analysis. The mean age of patients included was 47.2 years. A total of 382 (26.9%) patients had postoperative complications following a majority of implant-based IBR (929/1418). A total of 158 (11.1%) recurrences, which included 63 locoregional and 106 distant recurrences, was noted at a mean follow-up of 66 months. Although there was an increase in recurrence rates in the complication group (n = 66/382; 17.3% vs. n = 92/1036; 8.9%), there was no significant association between complications and BCR (17.3% vs. 8.9%; P = .18) or mortality (3.6% vs. 2.3%; P = .15). Time to adjuvant therapy was significantly increased in patients with complications (mean difference, 8.69 days; range, 1.18-16.21 days; P = .02; I2 = 0.02). This meta-analysis demonstrated a higher incidence of wound complications following IBR and a statistically significant increased time to adjuvant therapy. However, this did not translate into adverse oncological outcomes in patients with breast cancer undergoing IBR.

ABSTRACT

BACKGROUND: Administration of chemotherapy before breast surgery has the potential to reduce the risk of distant recurrence by targeting micrometastasis as well as allowing a more minimalistic approach to surgical intervention. We performed a systematic review to determine the optimum timing of surgery post breast cancer neoadjuvant chemotherapy (NACT). METHODS: The primary outcome was to determine whether the timing of surgery post NACT impacted overall survival (OS) and disease-free survival (DFS). We compared patient outcomes between those who had surgery within 8 weeks of completion of NACT to those that had surgery after 8 weeks. An outcome comparison between <4 weeks and 4-8 weeks was also performed. Secondary outcome included complete pathological response (pCR) post NACT. A meta-analysis was performed using the Mantel-Haenszel method. RESULTS: Five studies, including 8794 patients were eligible for inclusion. Patients that had surgery within 8 weeks of completion of NACT had a statistically significant improved OS(OR 0.47, 95% c. i 0.34-0.65) and DFS(OR 0.71 (95% c. i 0.52-0.98, P = 0.04). There were no survival advantages associated with having surgery less than 4 weeks post completion of NACT (OR 0.78, 95% c. i 0.46-1.33, P = 0.37). There was no difference in pCR rate between those that had surgery <4 weeks and 4-8 weeks (OR 1.01, 95% c. i 0.80-1.28, P = 0.93). CONCLUSION: This meta-analysis shows that the optimum timing of surgery post completion of NACT is 4-8 weeks as it is associated with increased OS and DFS.

ABSTRACT

BACKGROUND: Breast fibromatosis is a rare clinical entity, but poses significant diagnostic and therapeutic challenges. In light of recent changes in management practices, the aim was to review our institutional experience of breast fibromatosis and provide a review of current available literature on such management. METHODS: A search of pathological databases within two tertiary institutions for all patients diagnosed with fibromatosis of the breast over a 10-year period (2007-2016) was performed. Clinicopathological characteristics and modes of treatment were recorded for each patient. Concurrently a comprehensive literature search was performed and studies relating to breast fibromatosis and its management were identified and reviewed. RESULTS: Sixteen patients were identified. Median age at diagnosis was 42 (range 21-70) and all patients were diagnosed with core biopsy. The most useful imaging modality in diagnosis was ultrasonography and magnetic resonance imaging. 13/16 were treated surgically whilst 3/16 were treated using a watch-and-wait approach. 6/13 (46%) required re-excision of margins and 2/13 (15%) had recurrence after surgery. On review of the literature, there is no dedicated guideline in place for the management of breast fibromatosis. Currently a 'watch and wait' approach is favoured over surgical intervention due to high levels of recurrence and associated surgical morbidity. All cases should be discussed at a sarcoma multidisciplinary team meeting and tyrosine kinase inhibitors should be considered in advanced cases. CONCLUSIONS: Breast fibromatosis is rare but affects young patients. Active surveillance is now favoured over surgical resection due to high recurrence rates and extensive morbidity. Dedicated guidelines are required to ensure best outcomes.

ABSTRACT

Breast cancer is the most common cancer affecting European women and the leading cause of cancer-related death. A total of 15-20% of women who develop breast cancer have a family history and 5-10% a true genetic predisposition. The identification and screening of women at increased risk may allow early detection of breast cancer and improve prognosis. We established a family risk assessment clinic in May 2005 to assess and counsel women with a family history of breast cancer, to initiate surveillance, and to offer risk-reducing strategies for selected high-risk patients. Patients at medium or high risk of developing breast cancer according to NICE guidelines were accepted. Family history was determined by structured questionnaire and interview. Lifetime risk of developing breast cancer was calculated using Claus and Tyrer-Cuzick scoring. Risk of carrying a breast cancer-related gene mutation was calculated using the Manchester system. One thousand two hundred and forty-three patients have been referred. Ninety-two percent were at medium or high risk of developing breast cancer. Formal assessment of risk has been performed in 368 patients, 73% have a high lifetime risk of developing breast cancer, and 72% a Manchester score >or=16. BRCA1/2 mutations have been identified in 14 patients and breast cancer diagnosed in two. Our initial experience of family risk assessment has shown there to be a significant demand for this service. Identification of patients at increased risk of developing breast cancer allows us to provide individuals with accurate risk profiles, and enables patients to make informed choices regarding their follow-up and management.

Developed countries face significant population ageing in the near future. Within 20 years, the average age will approach 50 years and the largest population cohort will be those over 65 years. The incidence of breast cancer increases with age, with a risk in women of 0.44% by the age of 30, 3.82% by the age of 70 and 10% by the age of 80. Breast cancer is responsible for one out of every three cancer-related deaths. Elderly patients have higher mortality rates and most breast cancer-related deaths are observed in women over 65. There appears to be a trend that elderly patients with breast cancer receive less than the standard treatment compared to younger counterparts and this leads to poorer outcomes. The rationale for treating elderly breast cancer patients more conservatively is that breast cancers in this cohort are more commonly oestrogen receptor (ER) positive which gives the clinician the option to treat with hormonal manipulation alone. In addition, elderly patients present at a later stage compared to younger patients who frequently present with early (stages I and II) breast cancer. This review aims to give an overview of the diagnosis, treatment options and surveillance of breast cancer in elderly women (over 75 years) and to discuss the change in perception of the term 'elderly' and the reasons for undertreatment in the elderly patients.

ABSTRACT

INTRODUCTION: The rationalization of cancer services in Ireland saw all women with symptomatic breast problems referred to one of the eight regional cancer centers. A pilot triaging system was introduced in St Vincent's University Hospital to streamline these services. Women over 35 years who do not meet urgent referral criteria are referred for a mammogram prior to a clinic appointment ("image first"). The aim of this study was to retrospectively determine the recall rates, biopsy rates, and rate of breast cancer identification within this cohort of patients. This was compared to a screening population of patients. METHODS: Patients triaged into the "image first" group within a one-year period were identified. Results of the initial mammogram, further imaging and subsequent biopsies were recorded. Data relating to number of recalls, number of patients biopsied and number of cancers identified within the Merrion Unit of the National Breastcheck Screening Program was obtained for comparison. RESULTS: One thousand six hundred eighty-eight referrals were triaged as "image first" over this period. 185 (11%) of patients required a biopsy of an identified lesion. Breast cancer was diagnosed in 65 patients (3.9%). During the same study period, of the 42,099 women who were screened for breast cancer, 496 (1.8%) underwent biopsy and 267 (0.63%) were diagnosed with breast cancer. CONCLUSION: Image first patients, who represent a cohort of "symptomatic" non-urgent women, have a greater rate of breast cancer detection than an asymptomatic screening population. This may have an impact on the appropriate triaging of symptomatic women in a national cancer center.

ABSTRACT

Solid tumours contain regions of hypoxia, which may be a prognostic indicator and determinant of malignant progression, metastatic development and chemoradio-resistance. The degree of intra-tumoural hypoxia has been shown to be positively correlated with the expression of the transcription factor hypoxia-inducible factor 1. HIF-1 is composed of 2 sub-units, namely HIF-1alpha and HIF-1beta. The production of hypoxia inducible factor 1-alpha has been identified as a key element in allowing cells to adapt and survive in a hostile hypoxic environment via a variety of pathways. HIF-1alpha is stabilised by hypoxia at the protein level, and also by the oncogenes HER2neu, v-src and ras. There are over 60 target genes for HIF-1, many of which are activated in cancers in comparison to equivalent normal tissues. Chemotherapeutic modulation of HIF-1 pathways has shown promise for patients with chemo-radio resistant or recurrent tumours in Phase II clinical trials. We herein review the existing literature on hypoxia inducible factor-1alpha, particularly its role in carcinogenesis and clinical implications of its over-expression.

ABSTRACT

The 2nd International Consensus Conference for Breast Cancer in Young Women (BCY2) took place in November 2014, in Dublin, Ireland organized by the European School of Oncology (ESO). Consensus recommendations for the management of breast cancer in young women (BCYW) were updated from BCY1 with incorporation of new evidence to inform the guidelines, and areas of research priorities were identified. This manuscript summarizes these international consensus recommendations, which are also endorsed by the European Society of Breast Specialists (EUSOMA).
