Abstract
Breast surgery has evolved from mastectomy to breast-conserving surgery (BCS). Breast oncoplastic surgery later emerged with the inclusion and development of techniques used in plastic surgery for breast neoplasms. Recently, a new paradigm has been considered for mastectomy candidates with large multifocal and multicentric tumours, designated extreme oncoplasty (EO), which has allowed new techniques to be applied to tumours that would have been ineligible for BCS before. There are few publications and no uniform descriptions grouping all the technical possibilities and new indications together. We performed this a review with the objective of evaluating the indications and surgeries performed in the EO context, representing a new perspective for BCS. We observed new indications as extensive microcalcifications, locally advanced breast carcinoma with partial response to chemotherapy, small to moderate-sized non-ptotic central tumours and extreme ptosis. Small breasts are able for EO since the presence of ptosis. New surgeries are reported as disguised geometric compensation, perforators flaps, local/regional flaps, latissimus dorsi miniflap and partial breast amputation. It is important to decrease barriers to oncoplastic surgery if we want to increase the use of EO and BCS rates.

Survival Outcomes of Breast-Conserving Surgery Versus Mastectomy in Locally Advanced Breast Cancer Following Neoadjuvant Chemotherapy: A Meta-Analysis. Technol Cancer Res Treat 2024; 23:15330338241265030. [PMID: 39043051 PMCID: PMC11271104 DOI: 10.1177/15330338241265030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 05/03/2024] [Accepted: 06/06/2024] [Indexed: 07/25/2024] Open
Abstract
BACKGROUND Mastectomy (MT) and breast conservation surgery (BCS) are two common surgical options for the treatment of locally advanced breast cancer (LABC). Neoadjuvant chemotherapy (NACT) is frequently administered before surgery to shrink tumors and improve surgical outcomes. However, there is a lack of consensus on the optimal surgical approach after NACT and its impact on survival outcomes. OBJECTIVE This meta-analysis aims to compare the survival outcomes between MT and BCS in patients treated with NACT. METHOD A PRISMA selection was used to identify studies across electronic database such as PubMed, and Cochrane Library from inception until 11th July, 2023. A total of 10 comparative studies involving a total of 5018 patients were included. Among them, 2898 patients underwent MT while 2120 underwent BCS after receiving NACT. The outcomes assessed were the 5-year overall survival (OS) and 5-year disease-free survival (DFS). The data from the included studies were pooled, and odds ratios (OR) with 95% confidence intervals (CI) were calculated to evaluate the differences between MT and BCS in terms of survival outcomes. Prospero: CRD42024496831. RESULT The meta-analysis revealed that patients who underwent MT after NACT had a higher 5-year OS compared to those who underwent BCS (OR 2.68, 95% CI [2.19-3.28; p < 0.00001]). Additionally, the 5-year DFS was significantly better for patients who underwent MT (OR 3.11, 95% CI [1.80-5.38; p < 0.0001]). CONCLUSION MT after NACT may be associated with better 5-year OS and DFS compared to BCS.

Abstract
Breast Oncoplastic Surgery (OS) has established itself as a safe procedure associated with the treatment of breast cancer, but the term is broad, encompassing procedures associated with breast-conserving surgeries (BCS), conservative mastectomies and fat grafting. Surgeons believe that OS is associated with an increase in quality of life (QOL), but the diversity of QOL questionnaires and therapeutic modalities makes it difficult to assess from the patient's perspective. To answer this question, we performed a search for systematic reviews on QOL associated with different COM procedures, and in their absence, we selected case-control studies, discussing the main results. We observed that: (1) Patients undergoing BCS or breast reconstruction have improved QoL compared to those undergoing mastectomy; (2) In patients undergoing BCS, OS has not yet shown an improvement in QOL, a fact possibly influenced by patient selection bias; (3) In patients undergoing mastectomy with reconstruction, the QoL results are superior when the reconstruction is performed with autologous flaps and when the areola is preserved; (4) Prepectoral implants improves QOL in relation to subpectoral implant-based breast reconstruction; (5) ADM do not improves QOL; (6) In patients undergoing prophylactic mastectomy, satisfaction is high with the indication, but the patient must be informed about the potential complications associated with the procedure; (7) Satisfaction is high after performing fat grafting. It is observed that, in general, OS increases QOL, and when evaluating the procedures, any preservation or repair, or the use of autologous tissues, increases QOL, justifying OS.

Abstract
BACKGROUND The Geometric Compensation Technique (GCT) and the Split Reduction Technique (SRT) enables breast conserving surgery (BCS) in selected patients with breast cancer initially candidates to mastectomy. METHODS Observational study of patients with breast cancer who underwent GCT consecutively treated. Evaluated retrospectively: indications, clinical characteristics, surgical features and recurrences. Cosmesis were evaluated prospectively by the BCCT.core software, Harris/Harvard and Garbay scales. Descriptive statistics were performed, chi-square test was used to compare aesthetic outcomes; Kappa and Weighted Kappa test was used to assess agreement between the postoperative evaluations; Kaplan-Meier model for follow-up and recurrence. A systematic review was carried out using PRISMA methodology. RESULTS Thirty-six patients were evaluated, 26 (72.2%) with medium/large breasts with or without ptosis, seven (19.4%) with small breasts with or without ptosis, a profile undergoing GCT not previously identified in the literature. The mean tumor clinical size was 3.65 ± 1.59 cm. 34 (94.4%) patients underwent GCT. Mean follow-up time was 36.6 ± 16.8 months, with no local recurrences. According to BCCT.core, the postoperative aesthetic was good in 17 (51.5%) patients and 11 (33.3%) was reasonable. In the systematic review, 3.584 articles were evaluated, 20 articles were selected, 243 patients undergoing GCT were found, with several indications for BCS instead of mastectomy, with high rates of free margins, low recurrence and good aesthetic outcomes. CONCLUSION GCT, an oncologically safe and aesthetically satisfactory option, has been extended to patients with small and medium breasts with ptosis, large tumors to breast volume or in unfavorable resection sites, initially candidates for mastectomy.

Abstract
BACKGROUND Circulating tumor cells (CTCs) have been shown to be associated with the response to neoadjuvant chemotherapy (NCT) and the prognosis of locally advanced breast cancer (LABC) patients. Our study aimed to investigate whether the change of CTC status during NCT could serve as a supplement to the Response Evaluation Criteria in Solid Tumors (RECIST) in the treatment and evaluation of LABC patients. METHODS 6 ml of blood samples were collected before NCT, after the first cycle of NCT and after the completion of NCT, respectively. According to the change of CTC number during NCT, the patients were divided into "CTC low-response (low-R)" group and "CTC high-response (high-R)" group. Survival data of each group of patients were obtained through long-term follow-up. RESULTS A total of 35 patients diagnosed with LABC were enrolled. The median follow-up for distant metastasis was 27 months (range 7-36 months). There was no significant difference in distant metastasis-free survival (DMFS) between PR/CR group and PD/SD group (P = 0.0914), while CTC low-R group had a worse DMFS than CTC high-R group (P = 0.0199). In PR/CR subgroup, patients with CTC low-R showed a lower DMFS compared with those with CTC high-R (P = 0.0159). However, in PD/SD subgroup, there was no significant difference in DMFS between CTC low-R and CTC high-R group (P = 0.7521). In terms of assessing response to NCT, CTC change or RECIST classification alone had an AUC of 0.533 (95% CI 0.277-0.790) and 0.700 (95% CI 0.611-0.789), respectively. When combining the two, the AUC slightly increased to 0.713 (95% CI 0.532-0.895). CONCLUSION The change of CTC number during NCT has a potential to serve as a supplement to RECIST in the assessment of NCT efficacy and the prognosis of LABC patients.

Abstract
Background Breast cancer patients with skin ulcerations, satellite nodules or Peau d'orange at presentation are classified with stage 4 breast cancer (T4b). Neoadjuvant chemotherapy (NACT), followed by mastectomy, is the commonly accepted treatment in such patients for fear of adverse outcomes with breast conservation surgery (BCS) and uncertainty over sparing initially involved skin irrespective of the response to chemotherapy. Identifying patients with skin resolution post-NACT can help surgeons in decision-making. Aim To assess skin response in T4b breast cancer patients post-NACT and find the correlation between various clinical and pathological factors associated with no skin involvement on final histology. Methodology Records of breast cancer patients managed at the Tata Medical Center, Kolkata, with NACT for T4b breast carcinoma patients who underwent mastectomy were reviewed between January 2014 and December 2018. Final histology was checked for dermal involvement with the tumour. The Mann-Whitney U test was used for continuous variables for descriptive data, and Pearson's chi-squared and Fischer's exact tests were applied for categorical data. p-value < 0.05 was taken as significant. Results A total of 285 records mentioning skin involvement were reviewed, out of which 111 patients fulfilled the AJCC criterion. The median age at diagnosis of T4b breast cancer was 50 years. The median clinical size pre-chemotherapy was 7 cm. Residual median tumour size on final histology was reported as 1 cm. 78/111 patients showed a post-NACT response of 50% or more, and 43/111 showed a response of more than 90%. 57 (51.4%) patients showed skin involvement on final histopathology, while 54 (48.6%) patients did not.ER negative tumours were more likely to show no dermal involvement (p = 0.006). Residual tumour size of less than 1 cm on final histology (p < 0.05) and nodal stage were significant predictors of dermal response. Conclusion Approximately half of the T4b breast cancer patients showed resolution of dermal skin involvement post-NACT. ER negative and those with residual tumour size less than 1 cm post-NACT are more likely to show dermal resolution. This can help surgeons plan a BCS or skin sparing mastectomy for such patients who usually end up having a mastectomy.

Abstract
Breast interventions primarily comprise of biopsy of the suspicious breast lesions to obtain accurate pathological diagnosis. Generally, image-guided breast biopsy is required for nonpalpable lesions, however, even in palpable lesions, image-guided biopsy should be performed as it improves the accuracy of diagnosis. Image-guided breast interventions have progressed well beyond biopsy, making the radiologist an important part of the multidisciplinary management of breast cancer. Preoperative localization of nonpalpable abnormalities guides optimal surgical excision to obtain negative margins without sacrificing the normal tissue. Ablative procedures for breast cancer treatment such as radiofrequency ablation (RFA) and high-intensity focused ultrasound ablation can sometimes replace surgery in older patients with comorbidities. This article enumerates and describes the expanding spectrum of image-guided interventions performed by breast radiologist.

Abstract
Background In a country where radiotherapy (RT) is not available, advocacy based on the relevance of surgery + adjuvant RT in locoregional control and survival is needed. Aim To evaluate the impact of surgery with RT on local control and survival compared to surgery alone in breast cancer (BC). Methods and results Between 2007 and 2016, 210 patients with BC were retrospectively reviewed, of which 90 patients underwent surgery with RT (group 1) and 120 patients' surgery (group 2). There were several treatment combinations, including surgery combined with neoadjuvant chemotherapy [ACT], RT, and ACT. The results showed 88 (41.9%) cases of relapse, including 31 (34.4%) (group 1) and 57 (47.5%) (group 2) (p = .046). Recurrence occurred after a mean time of 1.5 years in group 1 versus 0.66 years in group 2 (p = .006). The 5‐year overall and BC‐specific survivals were 49.5% and 62.5%, respectively. The 5‐year survival was 60.0% (group 1) and 40.0% (group 2) (p < .05). In a multivariate analysis by Cox model, we found that the risk of death was 1.90 81 (95% CI [1.17 09–3.0701]) higher in group 2 (p = .009022), 1.69 85 (95% CI 1.00087–23.86157) in obese patients and decreased by 0.21 (95% CI [0.129–0.368]) in patients who did not relapse (p < .001). Conclusion In this study with several combination therapies, we cannot confirm that RT improves mainly locally advanced BC prognosis regardless of systemic treatment. However, we found that the risk of death correlated with the absence of RT, overweight, and risk of recurrence. Consideration of combinations of locoregional and systemic therapies, clinicopathological and biological data could improve the relevance of these results with a large sample size.

Abstract
Introduction Breast Conserving Surgery (BCS) with whole breast radiation is now standard of care as a safer alternative to Mastectomy in terms of loco-regional recurrence and long-term survival. Despite this, a frequent pitfall of conventional BCS is positive surgical margins and need for second surgery with a reported frequency of 12-59 % in literature. Oncoplastic Surgery can be a safer, more cost effective alternate to conventional BCS owing to its higher rate of negative surgical margins (4-6% vs 12-59 %) and better cosmetic results. We aim to prove utility of Oncoplastic surgery for Low-Middle income countries. Objective The aim of this study was to determine Oncoplastic Surgery as a more appropriate alternative to Conventional Breast Conserving Surgery for Low-Middle Income countries in terms of its lower positive margins and re-excision rates. Methodology A retrospective comparative single center study by reviewing patient's medical records from August 2016 to June 2020 was conducted. Rate of positive margins and re-excisions along with mean volume of resection specimen, mean tumor size and quadrant dealt by both surgical procedures were compared. Results Out of 421 patients 249 patients underwent oncoplastic surgery and were compared with 173 patients who had conventional breast conserving surgery. Positive margins were seen in 5 patients (2 %) in OPS group whereas in 31 (17.9 %) patients in BCS group (p value < 0.001). Therefore, 2 from OPS group and 17 from BCS group underwent re-excision (p value < 0.002).None in OPS group while 7 out of 17 patients in BCS group underwent mastectomy as second procedure. Mean tumor size in OPS group was 2.26 cm ± SD 1.66 and in BCS group was 1.94 cm ± SD 1.28. Majority of Lobular carcinoma and Ductal carcinoma in-situ, multifocal, upper inner and central quadrant tumors and those unresponsive to neo-adjuvant therapy were treated by Oncoplastic techniques. Conclusion Oncoplastic surgery has shown promising results as a safer tool to deal with large, complex tumors, lesions in difficult anatomical locations, multifocal or progressing on neo-adjuvant therapy. With its low Re-excision rates, it is a better alternative to traditional Breast Conserving approach for overburdened and resource limited health care system of Low-Middle Income countries. Multi-center, prospective trials are needed to determine its feasibility.

Abstract
BACKGROUND Breast-conserving treatment (BCT) provides better quality of life (QL) than mastectomy without reconstruction. Oncoplastic surgery (OS) encompasses a series of surgical techniques, increasing the indications for BCT, but few studies have evaluated the impact on QL in patients who undergo BCT with OS. MATERIALS AND METHODS A prospective, cross-sectional study was conducted in women who underwent BCT. We evaluated the characteristics of patients who underwent BCT with and without OS and the associated QL. QL was assessed through the EORTC QLQ-30, EORTC QLQ-BR23, and Breast Cancer Treatment Outcome Scale (BCTOS) questionnaires. RESULTS A total of 300 patients underwent BCT, 72 underwent breast OS, and 37 underwent bilateral surgery. Patients who underwent OS were younger (p = 0.004), had a higher level of education (p = 0.01), had a smaller time interval since the end of treatment (p = 0.02), had tumours with greater dimensions (p = 0.003), and were more likely to receive neoadjuvant chemotherapy (p = 0.05). Based on the QL questionnaires, no difference was observed between the groups. Breast symmetry was not associated with high patient satisfaction (p = 0.55). CONCLUSION Despite the fact that OS was performed in patients with worse tumour conditions and in more demanding patients, OS allowed similar cosmetic results to classical BCT.

Abstract
Abstract
Objective The aim of this study was to evaluate the efficacy and cardiotoxicity profile, and to reduce the extend of breast cancer surgery in primary systemic therapy (PST) HER2/neu–positive operable breast cancer patients.
Materials and Methods A total of 152 patients diagnosed from 2010 to 2015 were included in the study. The PST consisted of a sequential regimen of taxanes and anthracyclines plus trastuzumab. The clinical and pathological responses and the type of breast cancer surgery were evaluated and correlated with clinical and biological factors. The cardiotoxicity profile and long-term benefits were analyzed.
Results The median patient age was 47 (37–67) years, with T2 and T3 67 (44.1%) and 85 (55.9%), respectively. Axillary lymph node breast cancer at diagnosis N0 was 104 (68.4%) and N1 and N2 were 28.9% and 2.6%, respectively. A total of 95.7% of patients had nonspecific type of breast cancer, 67% of tumors were hormonal receptor–negative, 75.5% were grade III, 100% Ki67 > 20%, and 90% of tumors were confirmed to be HER2/neu–positive through immunohistochemistry. Following PST, pathological complete response (pCR) rate was achieved in 44.7% evaluable patients. The pCR rate was higher in HR-negative (93.1% vs. 6.9%) cancer and in grade III (86.2%) than in grade I and II (13.8%) cancer; only 75.5% of complete response (CR) on ultrasound and magnetic resonance imaging were also CR on pathology results. Breast conserving surgery was performed in 41.4%. Regarding type of chemotherapy, there were no significant differences between chemotherapy with anthracycline backbone or taxanes to achieved pathological complete response. Despite that, we were unable to demonstrate an association between pCR and better DFS with p = 0.096; HR 5.7 95.0% CI (0.73–45.52). Patients who are hormonal receptor positive tend to have lower disease-free survival (DFS) than those who are hormonal receptor negative; HR = 6.34, 95.0% CI (1.54–26.00) and p = 0.010. Five years DFS was higher for those who achieved pCR compare with those who did not. Even in this research we failed to show it is statistically significant.
Conclusion A sequential regimen of taxanes and anthracyclines plus trastuzumab was effective with high pCR rates and increases the possibility to do breast conservation surgery and had tolerable cardiotoxicity profile.

Abstract
PURPOSE The extended role of breast-conserving surgery (BCS) in the neoadjuvant setting may raise concerns on the oncologic safety of BCS compared to mastectomy. This study compared long-term outcomes after neoadjuvant chemotherapy (NAC) between patients treated with BCS and mastectomy. METHODS All breast cancer patients treated with NAC from 2008 until 2017 at the Amphia Hospital (the Netherlands) were included. Disease-free and overall survival were compared between BCS and mastectomy with survival functions. Multivariable Cox proportional hazard regression was performed to determine prognostic variables for disease-free survival. RESULTS 561 of 612 patients treated with NAC were eligible: 362 (64.5%) with BCS and 199 (35.5%) with mastectomy. Median follow-up was 6.8 years (0.9-11.9). Mastectomy patients had larger tumours and more frequently node-positive or lobular cancer. Unadjusted five-year disease-free survival was 90.9% for BCS versus 82.9% for mastectomy (p = .004). Unadjusted five-year overall survival was 95.3% and 85.9% (p < .001), respectively. In multivariable analysis, clinical T4 (cT4) (HR 3.336, 95% CI 1.214-9.165, p = .019) and triple negative disease (HR 5.946, 95% CI 2.703-13.081, p < .001) were negative predictors and pathologic complete response of the breast (HR 0.467, 95% CI 0.238-0.918, p = .027) and axilla (HR 0.332, 95% CI 0.193-0.572, p = .001) were positive predictors for disease-free survival. Mastectomy versus BCS was not a significant predictor for disease-free survival when adjusted for the former variables (unadjusted HR 2.13 (95%CI: 1.4-3.24), adjusted HR 1.31 (95%CI: 0.81-2.13)). In the BCS group, disease-free and overall survival did not differ significantly between cT1, cT2 or cT3 tumours. CONCLUSION BCS does not impair disease-free and overall survival in patients treated with NAC. Tumour biology and treatment response are significant prognostic indicators.

Abstract
BACKGROUND Therapeutic reduction mammoplasty (TRM) is a safe and effective surgical technique that has oncologic outcomes comparable with those achieved by mastectomy. This study aimed to compare surgical and patient-reported outcomes between breast cancer patients treated with TRM and those who had mastectomy with immediate reconstruction (MIR). METHODS A 4-year, single-institution, retrospective cohort study analyzed breast cancer patients undergoing TRM and MIR. Patient characteristics and perioperative data were collected from electronic records. Patient-reported outcome data were collected via BREAST-Q questionnaires preoperatively, then 3 months and 12 months postoperatively. A subgroup analysis was performed on locally advanced breast cancer (LABC) patients for TRM and MIR. RESULTS The study included 249 breast reconstructions, of which 77 (31%) were TRM and 172 (69%) were MIR. The mean follow-up time was 2.4 ± 1.2 years. Compared with MIR, TRM had significantly lower major complication rates (9% vs 21%; p = 0.02) and fewer revisionary surgeries (5% vs 37%; p < 0.0001). At 1 year postoperatively, TRM had a significantly greater change in satisfaction with breasts, (+ 27.7 vs + 4.6; p < 0.01) and sexual well-being (+ 20.0 vs - 5.5; p = 0.02) than MIR. CONCLUSION For select breast cancer patients, TRM continues to be a safe and effective alternative to mastectomy. The current study demonstrated that TRM patients had fewer major complications and revisionary surgeries, as well as better patient-reported outcomes than MIR.

Abstract
BACKGROUND Breast conservative treatment (BCT) is safe when it is performed in association with radiotherapy. The number of referral for BCT has increased, and it has become an important treatment modality. Patients who undergo BCT present some characteristics that are associated with better quality of life compared with patients who undergo mastectomy without reconstruction. Instruments that measure the quality of life specifically used in cases of BCT are limited. One of these instruments is the Breast Cancer Treatment Outcome Scale (BCTOS), which has not yet been translated into Brazilian Portuguese. It contains 22 questions and four domains (functional, aesthetic, breast sensitivity and oedema). METHODS We performed the translation and cultural adaptation process using Beaton's and EORTC translations process. In summary, the translation process is based on Portuguese translation, translation summary, reverse translation into English, expert committee, pre-test (10 patients), questionnaire review and test of the final version (6 patients). RESULTS All 16 patients were submitted to quadrantectomy and mammary radiotherapy. Lymphedema was present in 4, altered strength in 5, and altered shoulder mobility in 6 patients. Considering the questionnaire, the reconciled version determined change in 2 items. Pre-test evaluation showed difficulties in 3 patients, but the questionnaire did not change. Test evaluation showed no problems. CONCLUSION The translation of BCTOS into Portuguese will help us to evaluate the quality of life in BCT patients evaluating treatment-related sequelae and may be useful for oncoplastic surgery evaluation.

Abstract
Chemotherapy is an important comprehensive treatment for breast cancer, which targets micro-environment of tumors as well as their characterisitcs. A previous microarray analysis revealed that matrix metalloproteinase (MMP)-1 was highly upregulated in carcinoma-associated fibroblasts (CAFs) prior to and following treatment with Taxotere under co-culture conditions. However, whether the chemotherapeutic effects of Taxotere were influenced by the changes in MMP-1 remained unclear. The purpose of the present study was to investigate the impact and mechanism of CAFs in regulating the efficacy of Taxotere on breast cancer cells. CAFs isolated from primary invasive ductal human breast tumors following surgical resection, were used in co-culture with MDA-MB-231 cells to simulate the tumor micro-environment. Following the addition of Taxotere, changes in MMP-1 gene and protein expression were assessed by reverse transcription-quantitative polymerase chain reaction and western blot analysis, respectively. Proliferation, invasion and apoptosis assays revealed that when MMP-1 was upregulated in CAFs, the therapeutic efficacy of Taxotere was reduced in breast cancer cells. Chemosensitivity was significantly increased when MMP-1 expression was inhibited by GM6001. In addition, Collagen IV was upregulated in CAFs following chemotherapy and protected breast cancer cells against chemotherapeutic side effects. Collagen IV expression significantly decreased, as well as MMP-1 expression when GM6001 was added. Proliferation and invasion assays demonstrated that the exogenous addition of Collagen IV weakend the chemotherapeutic effect of Taxotere on breast tumor cells. Overall, the results revealed that in CAFs, MMP-1 synergized with Collagen IV as a key gene in regulating the chemotherapeutic effect of Taxotere on breast tumor cells and served an important role in reducing the efficacy of Taxotere on breast cancer, potentially via the transforming growth factor-β signaling pathway. These fidings provide a theoretical basis for the mechanism of CAFs in reducing the chemotherapeutic effect of Taxotere on breast cancer cells and a novel approach for enhancing the chemosensitivity of tumors.

Abstract
Acyl-CoA binding domain containing 3 (ACBD3) is involved in the maintenance of Golgi structure and function through its interaction with the integral membrane protein. However, the clinical significance and biological role of ACBD3 in breast cancer remain unclear. Herein, we found that the mRNA and protein levels of ACBD3 were markedly up-regulated in breast cancer cells and tissues. Immunohistochemical analysis of breast cancer tissues demonstrated that ACBD3 overexpression was significantly associated with advanced clinicopathological features. Univariate and multivariate analysis indicated that ACBD3 overexpression correlates with poor prognosis in breast cancer. Furthermore, overexpressing ACBD3 promoted, while silencing ACBD3 inhibited, self-renewal and tumorigenesis in breast cancer cells in vitro and in vivo respectively. Importantly, upregulating ACBD3 promoted the self-renewal and tumorigenesis of breast cancer cells via activating the Wnt/beta-catenin signaling, and the pro-self-renewal effect of ACBD3 in breast cancer was antagonized by the Wnt signaling inhibitor TCF4-siRNA and Lef1-siRNA.These findings indicate that ACBD3 may represent candidate therapeutic targets to enable the elimination of breast cancer stem cells, providing the preclinical proof-of-concept for the prevention and treatment of breast cancer.

Abstract
Purpose Neoadjuvant chemotherapy (NACT) is increasingly used in breast cancer treatment. One of the main goals of NACT is to reduce the extent of local surgery of the breast and axilla. The aim of this study was to determine surgical outcomes for patients receiving breast-conserving therapy (BCT) after NACT, including margin status plus secondary surgeries, excision volumes, and cosmetic outcomes. Methods A systematic review was performed in accordance with PRISMA principles. Pubmed, MEDLINE, Embase, and the Cochrane Library were searched for studies investigating the results of BCT following NACT. The main study outcomes were margin status, additional local therapies, excision volumes, and cosmetic outcomes. Non-comparative studies on NACT were also included. Exclusion criteria were studies with less than 25 patients, and studies excluding secondary mastectomy patients. Findings Of the 1219 studies screened, 26 studies were deemed eligible for analysis, including data from 5379 patients treated with NACT and 10,110 patients treated without NACT. Included studies showed wide ranges of tumor-involved margins (2–39.8%), secondary surgeries (0–45.4%), and excision volumes (43.2–268 cm3) or specimen weight (26.4–233 g) after NACT. Most studies were retrospective, with a high heterogeneity and a high risk of bias. Cosmetic outcomes after NACT were reported in two single-center cohort studies. Both studies showed acceptable cosmetic outcomes. Interpretation There is currently insufficient evidence to suggest that NACT improves surgical outcomes of BCT. It is imperative that clinical trials include patient outcome measures in order to allow monitoring and meaningful comparison of treatment outcomes in breast cancer.

Abstract
Background Breast conserving surgery (BCS) after neoadjuvant chemotherapy (NC) in patients with locally advanced breast cancer (LABC) is an infrequent procedure. In these patients the association with BCS and oncoplastic surgery (OS) is reported as a possible procedure in case-series, but there are limited case-control studies. Methods A matched case-control study evaluated LABC submitted to NC and BCS. We evaluated 78 patients submitted to doxorubicin-cyclophosphamide regimen followed by paclitaxel regimen. The match case-control proportion was 2:1 and the patients were selected by tumor size, clinical T stage and year of diagnosis. Results 52 underwent classic BCS and 26 OS. The average size tumor was 5.25 cm and 88.5% of the tumors were larger than 3 cm. The clinical and pathological group characteristics were similar, except the weight of surgical specimens (p = 0.004), and surgical margins (p = 0.06), which were higher in OS group. The rate of complete pathologic response was 26.9%. 97.4% received postoperative radiotherapy. At 67.1 months of follow up, 10.2% had local recurrence (LR) and 12.8% locoregional recurrence (LRR) and 19.2% died because disease progression. The overall survival at 60 months was 81.7%. After surgery the disease free-survival at 60 months was 76.5%. The was no difference between groups related to pathologic response (p = 0.42), LR (p = 0.71), LRR (p = 1.00), overall survival (p = 0.99) and disease specific survival (p = 0.87). Conclusion This study corroborates the fact that OS is a safety procedure for LABC, offering the similar oncologic results observed in patients submitted to classic BCS. A matched case-control study evaluates oncoplastic techniques for locally advanced breast cancer. The size of tumors were bigger than other series. The matched case-control study was selected base on tumor size and year of diagnosis to decrease possible bias selection. The security of this procedure was evaluated based a long follow up. Oncoplastic surgery has the same results than conventional breast conserving surgery for locally advanced breast tumors.
