Multimodal treatment of patients with advanced pelvic malignancies (APM) is challenging and surgical expertise is usually concentrated in highly specialised centres. Given significant regional variation in APM surgery, surgical training represents a cornerstone in standardising and future-proofing of this complex therapy. The aim of this study was to describe the availability and current satisfaction levels with surgical training for APM.An online questionnaire was developed and distributed through the Redcap© platform with 32 questions addressing participant and institution demographics, and training in APM surgeries. The survey was electronically disseminated in 2021 to surgical networks across Europe including all specialities treating APM via the European Society of Surgical Oncology (ESSO). All statistical analysis were performed using R.The survey received 280 responses from surgeons across 49 countries, representing general surgery (36%), surgical oncology (30%), gynaeoncology (15%), colorectal surgery (14%) and urology (5%). Fifty-three percent of participants report performing25 APM procedures/year. Respondents were departmental chiefs (12%), consultants (34%), specialist surgeons (40%) and fellows (15%). 34% were happy/very happy with their training with 70% satisfaction about their exposure to surgical procedures. Respondents reported a lack of standardised training (72%), monitoring tools (41%) and mentorship (56%). 57% rated attended courses as useful for training, while 80% rated visiting expert centres as useful.This study has identified a learning need for improved structured training in APM, with low current satisfaction levels with exposure to APM training. Organisations such as ESSO provide an important platform for visiting expert centres, courses, and structured training.

This study aims to compare patient-reported outcomes (PROs) after different types of oncoplastic surgery (OPS) procedures and correlate the results with previously published normative data from women with no prior history of breast cancer (BC) and breast surgery.Cross-sectional study of patients with stage I-II BC undergoing a specific selection of OPS procedures from 04/2012 to 12/2018 by three breast surgeons at a single tertiary referral hospital in Switzerland. PROs were evaluated using the postoperative BREAST-Q questionnaire.One hundred twenty-seven patients met the inclusion criteria and were surveyed. All OPS techniques achieved comparably elevated scores in satisfaction with breasts, psychosocial, and sexual well-being. Compared to normative data of healthy women, all OPS groups postoperatively achieved significantly better satisfaction with breasts, psychosocial, and sexual well-being.This study shows high PROs across all types of OPS, which were superior to normative data from healthy women. Our findings confirm that OPS is associated with high quality of life and patient satisfaction.

RxPONDER showed no benefit of adjuvant chemotherapy in postmenopausal women with estrogen receptor (ER) positive/human epidermal growth factor receptor 2 (HER2) negative breast cancer and limited nodal burden (pN1) with a recurrence score ≤ 25, suggesting that axillary staging could be omitted in cN0 patients if significant numbers of such women do not have pN2-3 disease. Here we evaluate the pN2-3 disease rate in a large cohort of postmenopausal women presenting with cN0 breast cancer.Consecutive postmenopausal patients presenting with T1-2N0 breast cancer who underwent axillary surgery from February 2006 to December 2011 were identified. Clinicopathologic characteristics associated with pN2-3 disease were examined using chi-square or Fisher's exact tests.Of 3363 postmenopausal women with cT1-2N0 breast cancer (median age 58 years, IQR 48-67 years), median tumor size was 1.3 cm (IQR 0.90-1.90cm). Post-axillary staging, 2600 (77.3%) were pN0, 643 (19.1%) were pN1, and 120 (3.6%) were pN2-3. The pN2-3 disease rate did not differ across subtypes (4.4% HER2In postmenopausal women with cN0 disease, pN2-3 nodal burden is uncommon; omitting axillary staging would not miss a significant number of patients who might benefit from adjuvant chemotherapy. Information available preoperatively indicating a higher risk of nodal disease such as younger age and large, multifocal tumors should be considered in the multidisciplinary management of the axilla.

Background and objectives The oncological benefit of axillary surgery (AS), with sentinel lymph node biopsy (SLNB) or axillary dissection (ALND), in elderly women affected by breast cancer (BC) is controversial. We evaluated AS trends over a 10-year follow-up period as well as locoregional and survival outcomes in this subset of patients. Methods Patients aged 70 years or older, treated between 1994 and 2008, were selected and divided in two groups, depending on whether or not AS was performed. A (1:1) matched analysis for all relevant clinicopathological features was performed. Outcomes were analyzed using the Kaplan–Meier method and univariate Cox-proportional hazard ratio analysis. Results A total of 1.748 patients were identified and stratified by age (70–74, 75–79, 80–84). A matched analysis was performed for 252 patients: 122 who underwent AS and 122 who did not. At 10-year follow-up, ipsilateral breast tumor recurrence, distant metastasis and contralateral BC were similar, p = 0.83, p = 0.42 and p = 0.28, respectively. In the no-AS group, a significant increased risk of axillary lymph-node recurrence was identified at 5- and confirmed at 10-years (p = 0.038), without impact on overall survival at 5- and 10-years (p = 0.52). In the non-AS group, higher rate of axillary recurrence at 10-years was observed in patients with poorly differentiated (24.1%, 95% CI 7.2–46.2), highly proliferative (Ki67 ≥ 20%: 17.1%, 95% CI 0.6–33.3) and luminal B tumors (16.8%, 95% CI 5.9–35.5). Conclusions Axillary staging in elderly women does not impact long-term survival. Tailoring surgery according to tumor biology and age may improve locoregional outcome.

Introduction The potential advantages of oncoplastic breast conserving surgery (BCS) have not been validated in robust studies that constitute high levels of evidence, despite oncoplastic techniques being widely adopted around the globe. There is hence the need to define the precise role of oncoplastic BCS in the treatment of early breast cancer, with consensual recommendations for clinical practice. Methods A panel of world-renowned breast specialists was convened to evaluate evidence, express personal viewpoints and establish recommendations for the use of oncoplastic BCS as primary treatment of unifocal early stage breast cancers using the GRADE approach. Results According to the results of the systematic review of literature, the panelists were asked to comment on the recommendation for use of oncoplastic BCS for treatment of operable breast cancer that is suitable for breast conserving surgery, with the GRADE approach. Based on the voting outcome, the following recommendation emerged as a consensus statement: Oncoplastic breast conserving surgery should be recommended versus standard breast conserving surgery for the treatment of operable breast cancer in adult women who are suitable candidates for breast conserving surgery (with very low certainty of evidence). Discussion This review has revealed a low level of evidence for most of the important outcomes in oncoplastic surgery with lack of any randomized data and absence of standard tools for evaluation of clinical outcomes and especially patients’ values. Despite areas of controversy, about one-third (36%) of panel members expressed a strong recommendation in support of oncoplastic BCS. Presumably, this reflects a synthesis of views on the relative complexity of these techniques, associated complications, impact on quality of life and costs.

Purpose Some studies have indicated age-specific differences in quality of life (QoL) among breast cancer (BC) patients. The aim of this study was to compare patient-reported outcomes after conventional and oncoplastic breast surgery in two distinct age groups. Methods Patients who underwent oncoplastic and conventional breast surgery for stage I-III BC, between 6/2011–3/2019, were identified from a prospectively maintained database. QoL was prospectively evaluated using the Breast-Q questionnaire. Comparisons were made between women Results One hundred thirty-three patients were included. Seventy-three of them were ≥ 60 years old. 15 (20.5%) of them received a round-block technique (RB) / oncoplastic breast-conserving surgeries (OBCS), 10 (13.7%) underwent nipple-sparing mastectomies (NSM) with deep inferior epigastric perforator flap (DIEP) reconstruction, 23 (31.5%) underwent conventional breast-conserving surgeries (CBCS), and 25 (34.2%) received total mastectomy (TM). Sixty patients were younger than 60 years, 15 (25%) thereof received RB/OBCS, 22 (36.7%) NSM/DIEP, 17 (28.3%) CBCS, and 6 (10%) TM. Physical well-being chest and psychosocial well-being scores were significantly higher in older women compared to younger patients (88.05 vs 75.10; p p = 0.002, respectively). In multivariate linear regression, longer time intervals had a significantly positive effect on the scales Physical Well-being Chest (p = 0.014) and Satisfaction with Breasts (p = 0.004). No significant results were found concerning different types of surgery. Conclusion Our findings indicate that age does have a relevant impact on postoperative QoL. Patient counseling should include age-related considerations, however, age itself cannot be regarded as a contraindication for oncoplastic surgery.

Funder: Amgen, Funder: Roche, Funder: Universitätsspital Basel, Funder: Merck, Funder: AstraZeneca, Funder: Pfizer, 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 recommendations 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.

In cN1 patients rendered cN0 with neoadjuvant chemotherapy, the false-negative rate of sentinel lymph node biopsy (SLNB) is 10% when ≥ 3 sentinel lymph nodes (SLNs) are removed. The added value of nodal clipping in this scenario is unknown. Here we determine how often the clipped node is a sentinel node when ≥ 3 SLNs are retrieved.We identified cT1-3N1 patients treated between 02/2018 and 10/2021 with a clipped lymph node at presentation. SLNB was performed with a standardized approach of dual-tracer mapping and retrieval of ≥ 3 SLNs. Clipped nodes were not localized; SLNs were X-rayed intraoperatively to determine clip location. Axillary lymph node dissection (ALND) was performed for any residual disease or retrieval of 3 SLNs.Of 269 patients, 251 (93%) had ≥ 3 SLNs. Median age was 51 years; the majority (92%) had ductal histology; 46% were HR+/HER2-. The median number of SLNs removed was 4 (IQR 3,5). The clipped node was an SLN in 88% (220/251) of cases. Of the 31 where the clipped node was not, 13 had a positive SLN mandating ALND, and the clip was identified in the ALND specimen. In the remaining 18, where ≥ 3 negative SLNs were retrieved and an ALND was not performed, the clip was not retrieved, with no axillary failures in this group (median follow-up: 55 months).When the SLNB procedure is optimized with dual tracer and retrieval of ≥ 3 SLNs, the clipped node is an SLN in the majority of cases, suggesting that failure to retrieve the clipped node should not be an indication for ALND.

Introduction: The majority of cancer patients report malnutrition, with a significant impact on patient's outcome. This study aimed to compare how nutritional assessment is conducted across different surgical oncology sub-specialties.Methods: Survey modules were designed for breast, hepato-pancreato-biliary (HPB), upper-gastrointestinal (UGI), sarcoma, peritoneal and surface malignancies (PSM) and colorectal cancer (CRC) surgeries to describe 4 domains: participants' setting, evaluation of clinical factors, use of screening tools and clinical practice. Results were compared among sub-specialties and according to human development index (HDI) in the largest cohorts.Results: Out of 457 answers from 377 global participants (62% European), 35.0% were from breast and 28.9% were from CRC surgeons. Although MDTs management is consistently reported (64-88%), the presence of a nutritionist/dietician ranges from 14.1% to 44.2%. Breast surgeons seldom evaluate albumin (25.6%) and weight loss (30.6%), opposite to HPB, PSM and UGI groups (>70%, p 0.044). Overall, responders declared that the use of screening tools is largely neglected, that nutritional status is often assessed by the surgeons and that nutrition is not consistently modified according to risk factors (range among groups respectively: 1.9%-25.6%, 33.1%-51.4%, 33.1%-60.5%). Less than 20% of breast surgeons assess patients before/after surgery, comparing to >60% of PSM surgeons. However, no statistical differences were documented comparing groups for the majority of the items of the 4 domains. Nutritional evaluation is more often conducted by breast surgeons in medium/low HDI countries comparing very high/high HDI (p 0.04).Conclusions: Nutritional assessment is largely neglected. These results identify target-issues for the implementation of clinical practice.

Axillary lymph node dissection (ALND) can be avoided in node-positive patients who receive neoadjuvant chemotherapy (NAC) if three or more negative sentinel lymph nodes (SLNs) are retrieved. We evaluate how often node-positive patients avoid ALND with NAC, and identify predictors of identification of three or more SLNs and of nodal pathological complete response (pCR). From November 2013 to July 2019, all patients with cT1-3, biopsy-proven N1 tumors who converted to cN0 after NAC received SLN biopsy (SLNB) with dual mapping and were identified from a prospectively maintained database. 630 consecutive N1 patients were eligible for axillary downstaging with NAC; 573 (91%) converted to cN0 and had SLNB, and 531 patients (93%) had three or more SLNs identified. Lymphovascular invasion (LVI; odds ratio [OR] 0.46, 95% confidence interval [CI] 0.24–0.87; p = 0.02) and increasing body mass index (BMI; OR 0.77, 95% CI 0.62–0.96 per 5-unit increase; p = 0.02) were significantly associated with failure to identify three or more SLNs. 255/573 (46%) patients achieved nodal pCR; 237 (41%) had adequate mapping. Factors associated with ALND avoidance included high grade (OR 2.51, 95% CI 1.6–3.94, p = 0.001) and receptor status (HR+/HER2− [referent]: OR 1.99, 95% CI 1.15–3.46 [p = 0.01] for HR−/HER2−, OR 3.93, 95% CI 2.40–6.44 [p

INTRODUCTION: The contralateral prophylactic mastectomy (CPM) rate in the U.S. has been steadily increasing. This is of particular concern because many women who undergo this procedure are candidates for breast-conserving surgery. AREAS COVERED: CPM’s medical benefit is related to the risk of contralateral cancer development and whether CPM provides a survival benefit. Contralateral cancer rates have decreased, and CPM does not provide a survival benefit. Other potential benefits of the procedure may be improved quality of life; these data are reviewed. Research efforts have been undertaken to better understand the decision-making process of patients who consider, and ultimately undergo, this procedure. EXPERT OPINION: Decisional traits, personal values, the desire for peace of mind, and the desire to obtain breast symmetry are important factors that drive a woman’s decision to undergo CPM. Additionally, many patients lack knowledge on how different types of breast surgery impact outcomes. To improve the shared decision-making process, a stepwise approach to address possible misconceptions, and clarify the real risks/benefits of this procedure should be utilized. A clear recommendation (for/against) should be made for every patient with newly diagnosed breast cancer who considers CPM. Communication tools to assist patients and surgeons in this process are sorely needed.

Introduction Recent data suggest that margins ≥2 mm after breast-conserving surgery may improve local control in invasive breast cancer (BC). By allowing large resection volumes, oncoplastic breast-conserving surgery (OBCII; Clough level II/Tübingen 5-6) may achieve better local control than conventional breast conserving surgery (BCS; Tübingen 1-2) or oncoplastic breast conservation with low resection volumes (OBCI; Clough level I/Tübingen 3-4). Methods Data from consecutive high-risk BC patients treated in 15 centers from the Oncoplastic Breast Consortium (OPBC) network, between January 2010 and December 2013, were retrospectively reviewed. Results A total of 3,177 women were included, 30% of whom were treated with OBC (OBCI n = 663; OBCII n = 297). The BCS/OBCI group had significantly smaller tumors and smaller resection margins compared with OBCII (pT1: 50% vs. 37%, p = 0.002; proportion with margin p < 0.001). There were significantly more re-excisions due to R1 (“ink on tumor”) in the BCS/OBCI compared with the OBCII group (11% vs. 7%, p = 0.049). Univariate and multivariable regression analysis adjusted for tumor biology, tumor size, radiotherapy, and systemic treatment demonstrated no differences in local, regional, or distant recurrence-free or overall survival between the two groups. Conclusions Large resection volumes in oncoplastic surgery increases the distance from cancer cells to the margin of the specimen and reduces reexcision rates significantly. With OBCII larger tumors are resected with similar local, regional and distant recurrence-free as well as overall survival rates as BCS/OBCI.

Oncoplastic techniques allow resection of larger tumors, permitting breast conservation in cases otherwise requiring mastectomy. We sought to prospectively compare quality of life (QoL) in patients undergoing oncoplastic surgery as compared to conventional breast conservation (CBC) or mastectomy is lacking.Patients diagnosed with BIRADS IV-VI lesion were eligible if resection of ≥10% of the breast volume was planned. Patients were allowed to decide whether they wanted to undergo CBC or oncoplastic breast conservation (OBC). Patients who underwent mastectomy and immediate breast reconstruction (IBR) were also included for comparison. The primary endpoint was breast self-esteem using the Breast Image Scale (BIS) at 12 months, secondary endpoints were perioperative morbidity and QoL using the BREAST-Q questionnaire.From 2011 to 2016, 205 patients were included in the study. 116 patients (56.6%) received CBC, 46 (22.4%) OBC and 43 (21%) MIBR. Women in the OBC group were more likely to have tumors ≥ 2 cm than those in the CBC group (34.7% vs. 17.5%, respectively). Women who underwent MIBR were more likely to have tumors5 cm than those in the CBC and OBC groups (23% vs 1% and 10%, respectively). The BIS and BREAST-Q improved in each group after 12 months but did not differ significantly between groups at any time point. Surgical complications (seroma, bleeding, infection, necrosis) were numerically more likely in the OBC and MIBR groups.OBC and the MIBR allow for resection of larger tumors with a similar quality of life as CBC.

Patients often fear axillary lymph node dissection (ALND) because of its associated complications; however, its effect on quality of life (QOL) is not well described. We aimed to evaluate the effect of ALND on QOL over time and to identify predictors of worse QOL.Breast cancer patients undergoing ALND were enrolled in a prospective lymphedema screening study. Arm volumes were measured and QOL questionnaires completed at baseline, postoperatively, and at 6-month intervals. The upper limb lymphedema-27 questionnaire was used to assess the effect of upper extremity symptoms on QOL in three domains (physical, psychological, and social). Predictors of QOL were identified by univariate and multivariable regression analyses.From November 2016 through March 2020, 304 ALND patients were enrolled; 242 patients with at least two measurements and 6 months of follow-up were included. Median age was 48 years, and median follow-up was 1.2 years. The 18-month lymphedema rate was 18%. Overall, QOL scores in all three domains decreased postoperatively and improved over time. On multivariable analysis, after adjusting for baseline scores, symptoms necessitating lymphedema therapy referral (p = 0.006) were associated with worse physical QOL. Younger age (p = 0.005) and lymphedema therapy referral (p = 0.006) were associated with worse psychological QOL. Arm volume was not correlated with QOL.QOL scores initially decreased after ALND but improved by 6 months post-surgery. Decreases in QOL were independent of arm volume. Patients with worse QOL more often sought lymphedema therapy, although the effect of therapy on QOL remains unknown.

One of the most important news occurring in axillary surgery since the last St. Gallen Conference in 2017 was the publication of confirmatory long-term follow-up data from several large multicenter phase III non-inferiority trials, which clearly showed that axillary dissection can no longer be considered standard practice in all node-positive patients. Several groups are currently investigating the most accurate method to reliably determine axillary pathologic complete response after neoadjuvant chemotherapy to omit axillary dissection in initially clinically node-positive patients. Concerning breast surgery, after publication of the broadly endorsed definition of “no ink on tumor” for negative margins, many groups have demonstrated the expected decrease in re-excision rates. More evidence is needed to evaluate the adequate margin width in the neoadjuvant setting, where an increased risk of local recurrence has been shown compared to the upfront surgery setting. Besides narrowing margins and local down-staging by neoadjuvant therapy, another potential way to increase breast conservation rates is eliminating multicentricity as a contraindication. This requires high-volume tumorectomy, which has been demonstrated to be oncologically safe in a large series of oncoplastic reduction mammoplasties. However, the beneficial impact of oncoplastic surgery on quality of life still needs to be confirmed. The Oncoplastic Breast Consortium (OPBC) is a rapidly growing global non-profit organization that is committed to identifying and prioritizing knowledge gaps in this field. Currently, the OPBC focuses on research projects that address the major heterogeneity in breast reconstruction practice after nipple-sparing mastectomy.

Breast cancer patients with local and/or locoregional recurrence (LR) are at higher risk of developing distant metastases (DM) at a later time. Once LR has been confirmed, some international interdisciplinary guidelines recommend performing radiological examinations for DM to determine the course of further therapy (curative or palliative approach). This study analyzed the metastatic patterns of patients with LR with particular regard to the frequency of concurrent diagnosis of LR and DM; in other words: are radiological staging procedures actually justified for DM at the time of diagnosis of LR? This study included all patients (n = 1368) who were diagnosed and treated for nonmetastatic breast cancer (Stage I–III) at the University Women’s Hospital Basel, Switzerland between 1990 and 2009. In 137 patients, LR was diagnosed without a history of DM: in-breast/thoracic wall only, n = 90 (65.7%); involvement of axillary/supra-/infraclavicular lymph nodes, n = 47 (34.3%). DM was found at the time of diagnosis of LR in 44 patients (32.1%). Concurrent diagnosis of LR and DM occurred significantly more often in patients with lymph node recurrence compared with those with in-breast/chest wall recurrence (48.9% vs. 23.3%; p = 0.004). Approximately one-third of patients with a LR had synchronous DM at the time of their local/locoregional event. For this reason, routine systemic staging imaging at the time of LR should be an absolute requirement for planning further therapy. Confirmation of DM may spare the patients radical surgical interventions with questionable impact on survival in the face of an incurable disease.

Breast cancer (BC) is the most frequent cancer in women and the leading cause of cancer death in females worldwide. Rapid research advancements add to the complexity of treatment options for this disease. It is known that the quality of patients’ care is deeply affected by healthcare professionals following these advancements. There is a growing need for academic education to increase clinical knowledge and skills of physicians treating BC patients. The certificate of Competence in Breast Cancer Program (CCB) is a Certificate in Advanced Studies (CAS) organized by the European School of Oncology in cooperation with Ulm University (Germany), which focuses on both the clinical and scientific competence required for improving quality in the management of BC patients. This paper describes the experience of the second CCB cohort (CCB2), which brought together 24 physicians from four continents who shared the common will to improve their competence and skills in BC treatment.

Postoperative complications after breast cancer surgery may be associated with decreased quality of life. It remains unclear whether oncoplastic breast-conserving surgery or mastectomy with reconstruction lead to more postoperative complications than conventional breast surgery (CBS). As delayed wound healing (DWH) is one of the most frequent minor complications, we sought to investigate the significance of DWH for patient-reported outcomes after oncoplastic, reconstructive, and CBS.Our study is a retrospective cohort study of consecutive patients with stage I-II breast cancer who underwent oncoplastic or CBS performed by three breast surgeons at a single tertiary referral hospital from June 2011 until May 2019. Patient-reported outcomes were evaluated postoperatively using the BREAST-Q questionnaire. Comparisons were made between patients with and without DWH.A total of 229 patients who met the inclusion criteria and 28 (12%) of them developed DWH, 27/158 (17%) in the oncoplastic breast-conserving surgery and reconstruction group and 1/71 (1%) in the CBS group. The mean time from surgery to BREAST-Q assessment was comparable in both groups (29 months in the DWH vs. 33 months in the normal wound healing group). No statistically significant difference for any BREAST-Q scale was detected between patients with and without DWH. This includes physical (p = 0.183), psychosocial (p = 0.489), sexual well-being (p = 0.895), and satisfaction with breasts (p = 0.068).Our study confirms that oncoplastic breast-conserving surgery and mastectomy with reconstruction lead to significantly more DWH than CBS. However, neither quality of life nor patient-reported outcomes following state-of-the-art reconstructive or oncoplastic breast-conserving surgery at a specialized center seem to be compromised.

Neoadjuvant endocrine therapy (NET) is effective in downstaging large hormone receptor-positive (HR+) breast cancers and increasing rates of breast-conserving surgery (BCS), but data regarding nodal pathologic complete response (pCR) are sparse. We reported nodal and breast downstaging rates with NET, and compared axillary response rates following NET and neoadjuvant chemotherapy (NAC). Consecutive stage I–III breast cancer patients treated with NET and surgery from January 2009 to December 2019 were identified from a prospectively maintained database. Nodal pCR rates were compared between biopsy-proven node-positive patients treated with NET, and HR+/HER2- patients treated with NAC from November 2013 to July 2019. 127 cancers treated with NET and 338 with NAC were included. NET recipients were older, more likely to have lobular and lower-grade tumors, and higher HR expression. With NET, the nodal pCR rate was 11% (4/38) of biopsy-proven cases, and the breast pCR rate was 1.6% (2/126). Nodal-dowstaging rates with NET and NAC were not significantly different (11% vs 18%; P = 0.37). Patients achieving nodal pCR with NET versus NAC were older (median age 70 vs 50, P = 0.004) and had greater progesterone receptor (PR) expression (85% vs 13%, P = 0.031), respectively. Of patients not candidates for BCS due to a large tumor relative to breast size, 36/47 (77%) became BCS-eligible with NET (median PR expression 55% vs 5% in those remaining ineligible, P

Background: The aim of this study was to compare the risk of complications and recurrence between oncoplastic and conventional breast surgery. Methods: This is a retrospective analysis of a consecutive series of 436 patients with stage I–III breast cancer who underwent surgery at the University Hospital of Basel between 2011 and 2018. Results: The nipple/skin-sparing mastectomy (NSM/SSM) group showed significantly more delayed wound healing (32.7 vs. 5.8%, p < 0.001) and skin necrosis (13.9 vs. 1.9%, p = 0.020) compared to conventional mastectomy (CM), which corresponded to significantly higher odds of short-term complications (OR 2.34, 95% CI 1.02–5.35, p = 0.044). The incidence rate of long-term morbidity in oncoplastic breast-conserving surgery (OBCS) was significantly higher compared to conventional breast-conserving surgery (CBCS; 25.5 vs. 11.3 per 100 patient years [PY], p < 0.001), in particular concerning chronic pain (13.3 vs. 6.6, p = 0.011) and lymphedema (4.1 vs. 0.4, p = 0.003). Seroma as a long-term morbidity occurred more often in the CM group compared to the NSM/SSM group (5.8 vs. 0.5 per 100 PY, p = 0.004). Patients received adjuvant treatment earlier after CM compared to NSM/SSM (HR 1.83, 95% CI 1.05–3.19, p = 0.034). There were no significant differences in the incidence of positive margins nor in the odds of recurrence after OBCS versus CBCS and after NSM/SSM versus CM. Conclusions: Even though the present study confirmed expected differences in complications and morbidity, it suggested that oncoplastic surgery is oncologically safe. Patients undergoing NSM/SSM should be followed closely to allow early detection and treatment of frequently associated complications and ensure timely start of adjuvant therapy.

Neoadjuvant chemotherapy (NAC) has been proven to increase breast-conserving surgery (BCS) rates, but data are limited on conversion rates from BCS-ineligible (BCSi) to BCS-eligible (BCSe), specifically, in patients with large tumors. Consecutive patients with stage I–III breast cancer treated with NAC from November 2013 to March 2019 were identified. BCS eligibility before and after NAC was prospectively determined. Patients deemed BCSi before NAC due to large tumor size were studied. Statistical analyses were conducted using Student’s t-test, Wilcoxon rank sum test, Chi-square test, Fisher’s test, and logistic regression. In this study, 600 of 1353 cancers were BCSi with large tumors; 69% were non-BCS candidates, 31% were borderline-BCS (bBCS) candidates. Of non-BCS candidates, 69% became BCSe after NAC; 66% chose BCS, and 90% were successful. Among bBCS candidates, 87% were BCSe after NAC, 73% chose BCS, and 96% were successful. On univariate analysis, bBCS candidacy, lower cT stage, cN0 status, absence of calcifications, human epidermal growth factor receptor 2 positive (HER2+)/triple negative (TN) receptor status, poor differentiation, ductal histology, and breast pCR were associated with conversion to BCS eligibility. On multivariable analysis, receptor status (hormone receptor positive [HR+]/HER2– ref; odds ratio [OR] HER2+ 1.63, P = 0.047; HR–/HER2– OR, 2.26, P = 0.003) and breast pCR (OR 2.62, P

Background: We challenge the concept of metastatic breast cancer (MBC) as a chronic disease. Methods: We analyzed an unselected cohort of 367 patients who were diagnosed with MBC over a 22-year period (1990–2011). Results: In order to create a “chronic disease subgroup”, we separated those patients from the entire cohort in whom systemic therapy was not applied after the diagnosis of MBC (n = 53; 14.4%). Three hundred fourteen patients (85.6%) comprised the “chronic disease subgroup”. The vast majority of those patients (89.8%) died of progressive disease after a median metastatic disease survival (MDS) of 25 months. Twenty patients (6.4%) died of non-MBC-related causes (MDS 38.5 months). Approximately 1 in 4 patients (26.8%) died within the first year after the MBC diagnosis. The 3- and 5-year MDS rates were 35.4 and 16.2%, respectively. Only 12 patients (3.8%) were exceptional survivors (MDS >10 years). Conclusion: The term “chronic disease” might be appropriate in selected MBC cases, bringing MBC into alignment with “classical” chronic diseases such as diabetes and hypertension. However, most cases display fundamental differences with regard to temporal progression and above all the case fatality rate. More than 90% of patients in the “chronic disease subgroup” died of the disease with a MDS of 2–3 years (even those who underwent systemic palliative therapies). Doctors and patients might understand the term “chronic disease” differently. The term must be used sparingly and explained carefully in order to create a common level of communication based on a shared understanding which avoids awakening false hopes and fostering misleading expectations.

Since its introduction nearly 30 years ago, sentinel lymph node biopsy (SLNB) has become the standard technique to stage the axilla for the great majority of patients with early breast cancer. While the accuracy of SLNB in clinically node-negative patients who undergo neoadjuvant chemotherapy (NAC) is similar to the upfront surgery setting, modifications of the technique to improve the false negative rate are necessary in node-positive patients at presentation. Currently, patients who present with matted nodes, cN1 patients who fail to downstage to cN0 with NAC and those with pathological residual disease have an indication to undergo axillary lymph node dissection. Ongoing trials will confirm if extensive nodal irradiation can replace surgery in patients with residual nodal disease after NAC and if nodal radiotherapy can be omitted in patients who achieve nodal pathological complete response. The aim of this review was to focus on the open questions on the management of the axilla after NAC.

Introduction Delay between clinical presentation and treatment of breast cancer (BC) can significantly impact mortality. We aimed at drawing a picture of women with locally advanced breast cancer (LABC) treated at our Breast Unit and at investigating factors associated with treatment delay. Material and methods A retrospective descriptive analysis, using a specific 28-item semi-structured questionnaire, was conducted in 67 patients diagnosed with T4 BC. Results Nearly a third of our patients had at least one known predisposing factor for LABC. 42% of patients did not perform routine medical breast checks, 49% reported indifference as the first feeling and 47% waited at least 3 months before seeking medical attention. The reasons for diagnostic delay were different in the various age groups. Doctor's delay in making the right diagnosis occurred in 60% of younger patients (≤40 years, n = 5), whereas among women aged 41–69years (n = 34) 50% suffered from psychiatric comorbidities. In patients ≥70 years (n = 28) social factors such as isolation, being widowed and living in a retirement home were present in most of the cases. Delay in seeking medical care was also associated with increasing age. Across all age groups, coping factors such as denial and indifference were also associated with an increase in the odds of delayed presentation, as opposed to fear. Conclusions Factors possibly explaining late medical consultation seem to differ according to age. Psychological factors are crucial in patients' delay whereas age and social factors are relevant in doctors' and system's delay.

The Breast Surgery theoretical and practical knowledge curriculum comprehensively describes the knowledge and skills expected of a fully trained breast surgeon practicing in the European Union and European Economic Area (EEA). It forms part of a range of factors that contribute to the delivery of high quality cancer care. It has been developed by a panel of experts from across Europe and has been validated by professional breast surgery societies in Europe. The curriculum maps closely to the syllabus of the Union of European Medical Specialists (UEMS) Breast Surgery Exam, the UK FRCS (breast specialist interest) curriculum and other professional standards across Europe and globally (USA Society of Surgical Oncology, SSO). It is envisioned that this will serve as the basis for breast surgery training, examination and accreditation across Europe to harmonise and raise standards as breast surgery develops as a separate discipline from its parent specialties (general surgery, gynaecology, surgical oncology and plastic surgery). The curriculum is not static but will be revised and updated by the curriculum development group of the European Breast Surgical Oncology Certification group (BRESO) every 2 years.

Ductal carcinoma in situ (DCIS) is a heterogenous disease. The mainstay of its management is surgery, and lumpectomy with or without radiation therapy (RT) or mastectomy are standard options. Endocrine therapy may be given to maximize risk reduction. With standard treatment, the longterm breast cancer-specific survival is excellent and exceeds 95%. Currently, management strategies are based on standard clinicopathological features. Genomic tools to predict local recurrence have been developed, and prospective studies to evaluate their impact on RT recommendations and outcomes are ongoing. Because of concerns regarding overtreatment of DCIS, there has been much enthusiasm for de-escalating locoregional therapy. RT halves the risk of local recurrence but does not affect survival, and its omission can be considered in low-risk groups. Active surveillance for lowrisk DCIS is being evaluated in 4 prospective trials. The concern regarding these trials is whether the selected "low-risk" cases are truly at low risk, and what threshold of recurrence is considered acceptable. Additionally, it is unclear whether patients will be willing to trade short outpatient procedures for more biopsies, more imaging, and possibly increased concern about recurrence. The clinical relevance and the safety of this approach are yet to be determined.
