Oncoplastic breast surgery (OBS) arose to decrease the deformity following breast-conserving surgery (BCS) for breast cancer. In this meta-analysis (MA), we pool BREAST-Q questionnaire data to compare quality of life (QOL) in breast cancer patients who received BCS alone or in combination with level I or II oncoplastic breast surgery (BCS + OBS). All relevant databases were searched following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and QUOROM (Quality of Reporting of Meta-Analyses) guidelines. All prospective or retrospective studies with a BCS or BCS + OBS cohort that reported QOL as assessed with the BREAST-Q questionnaire were eligible. Fifty-five studies (75 distinct patient cohorts; 11,186 patients) were included in the MA, with 12 studies reporting both preoperative and postoperative values and eligible for a pair-wise MA. The pair-wise MA showed a significant postoperative improvement in the overall satisfaction with the breast (mean difference [MD] +8.0%, P = .003) and in the psychosocial well-being (MD +9.2%, 3.5-14.8, P = .001) of the entire cohort (BCS and BCS + OBS). A subgroup MA of proportions highlighted a superiority of BCS + OBS to BCS in overall satisfaction with the breast (72.0%, 68.0-76.1, vs 62.9%, 58.3-67.5; P = .02) and psychosocial well-being (78.9%, 71.5-86.4, vs 73.3%, 67.3-76.5, P = .0001). A leave-1-out sensitivity analysis confirmed the results of the pair-wise MA and the MA of proportions. Oncoplastic breast surgery effectively improves QOL and patient satisfaction based on the patient-reported outcomes assessed with the BREAST-Q questionnaire. The improvements were associated with acceptable complication rates, further supporting BCS followed by OBS when mastectomy would otherwise be necessary., (© The Author(s) 2024.

Background: Oncoplastic surgery is an expanding approach for managing breast conservation because it offers improved cosmetic outcomes while maintaining oncological safety., Objectives: This study aimed to assess the oncological and surgical outcomes of patients who underwent oncoplastic procedures at a single institution., Methods: The study population includes all consecutive breast cancer patients who underwent lumpectomy followed by immediate oncoplastic breast reconstruction with contralateral breast adjustment between 2010 and 2021. Following IRB approval, patient demographics, tumor characteristics, surgical details, complications, and follow-up were evaluated for this group. Quality of life (QOL) and patient-reported outcome measures were assessed through questionnaires., Results: Following multidisciplinary tumor board discussion, 77 patients (82 breasts) underwent oncoplastic surgery. Of these, 92.2% underwent breast MRI prior to surgery with mean mass enhancement of 2.35 cm (range, 0-8.5 cm) and non-mass enhancement of 5.77 cm (range, 0-14 cm), and 44% presented with multifocal disease. The final positive surgical margin rate was 2.4%, and all conserved breasts received adjuvant radiation therapy. The 5-year local recurrence rate for invasive tumors was 4.1%. QOL scores were generally high, with most patients reporting good to excellent cosmetic outcomes and high personal satisfaction with breast appearance and softness. Physicians reported breast symmetry in 89.5%., Conclusions: The findings suggest that oncoplastic surgery with contralateral breast adjustment is safe, effective, and an excellent option for breast cancer patients wishing for breast conservation even for large or multifocal masses, with favorable oncologic and cosmetic outcomes. The QOL analysis indicates high patient satisfaction. These results support the use of oncoplastic surgery in the management of breast cancer., (© The Author(s) 2024.

Objective: The Food and Drug Administration approved the MRI-compatible wireless SCOUT localization system in April 2022. The purpose of this study was to evaluate feasibility of SCOUT localization under MRI guidance. We present our initial experience adopting MRI-guided SCOUT localization and compare it to MRI-guided wire localization., Methods: Electronic medical records and imaging were retrospectively reviewed for all patients who underwent MRI-guided SCOUT or wire localization at our institution between October 2022 and July 2023. Statistical analysis was performed using 2-sample proportion and Wilcoxon rank-sum tests., Results: There were 14 MRI-guided SCOUT and 23 MRI-guided wire localization cases during the study period. All SCOUTs were placed without complication and were considered to be in adequate proximity to the target. There was no significant difference in complication rate (P = .25) or days lapsed from MRI-detected abnormality to surgery (P = .82) between SCOUT and wire cases. SCOUT was placed at time of biopsy for 71% (10/14) of cases. 57% (8/14) of SCOUT cases were used for breast conservation surgery (BCS) compared to 100% (23/23) of wire cases (P <.01), with all 6 SCOUTs not used for BCS placed at time of biopsy., Conclusion: MRI-guided SCOUT localization is feasible and offers an alternative to MRI-guided wire localization, with no SCOUT complications reported. SCOUT placement at time of biopsy obviates the need for an additional procedure, but predicting appropriateness is challenging, with 60% (6/10) of SCOUTs placed at time of MRI-guided biopsy not used for subsequent localization surgery., (© Society of Breast Imaging 2024.

Background: Oncoplastic breast-conserving surgery may allow women with early breast cancer to avoid a mastectomy, but many women undergo more extensive surgery, even when breast-conserving options are offered. The aim of the ANTHEM qualitative study was to explore factors influencing women's surgical decision-making for and against oncoplastic breast-conserving surgery., Methods: Semi-structured interviews were conducted with a purposive sample of women who had received either oncoplastic breast-conserving surgery or a mastectomy with or without immediate breast reconstruction to explore their rationale for procedure choice. Interviews were transcribed verbatim and analysed thematically. Trial registration number: ISRCTN18238549., Results: A total of 27 women from 12 centres were interviewed. Out of these, 12 had chosen oncoplastic breast-conserving surgery and 15 had chosen a mastectomy with or without immediate breast reconstruction. Overwhelmingly, women's decisions were guided by their surgical teams. Decision-making for and against oncoplastic breast-conserving surgery was influenced by three key inter-related factors: perceptions of oncological safety; the importance of maintaining/restoring femininity and body image; and practical issues. Oncological safety was paramount. Women who reported feeling reassured that oncoplastic breast-conserving surgery was oncologically safe were happy to choose this option. Those who were not reassured were more likely to opt for a mastectomy, as a perceived 'safer' option. Most women wished to maintain/restore femininity, with the offer of immediate breast reconstruction essential to make a mastectomy an acceptable option. Practical issues such as the perceived magnitude of the surgery were a lesser concern., Conclusion: Decision-making is complex and heavily influenced by the surgical team. High-quality, accurate information about surgical options, including appropriate reassurance about the short- and long-term oncological safety of oncoplastic breast-conserving surgery is vital if women are to make fully informed decisions., (© The Author(s) 2024.

Introduction: Different intraoperative techniques with varying levels of evidence are available to decrease positive surgical margins during breast conserving surgery. The aim of this review is to assess the effectiveness of the MarginProbe® device as an intraoperative adjunct tool in reducing positive surgical margins, and subsequently exploring the effect on patient re-excision rates., Methodology: A systematic review of the available medical literature was conducted from 2007 to March 2022. A literature search of Cochrane, PubMed and Embase by two independent reviewers reviwers was performed to identify eligible articles looking at the primary outcome of percentage reduction in patient re-excision rates using MarginProbe®. Secondary outcomes analysed were comparison of tissue volume removed, absolute and relative reduction in re-excision rate, cosmetic outcome, as well as MarginProbe® sensitivity and specificity., Results: A total of 12 full text articles were identified. An independent samples t-test using a total of 2680 patients found a 54.68 per cent reduction in re-excision rate with the use of MarginProbe®, which was statistically significant with a large effect size (P < 0.001; d = 1.826). Secondary outcomes showed a relatively higher sensitivity of the MarginProbe® device, at the expense of decreased specificity, and no significant impact on cosmesis and volume of breast tissue excised., Conclusion: MarginProbe® is an effective intraoperative adjunct in breast-conservation surgery that reduces patient re-excision rates, with no adverse effects relating to breast cosmesis or increase in volume of excised tissue., (© The Author(s) 2023.

Background: Oncoplastic procedures allow excision of larger breast tumours, or unfavourable tumour/breast ratio lesions while achieving a good cosmetic outcome. This increases the pool of patients eligible for breast conservation over mastectomy, reducing the need for more extensive surgery in older women and potentially improving their quality of life. Nonetheless, studies to date suggest a poor uptake of oncoplastic breast surgery in the older group. This review aimed to establish whether a disparity in uptake of oncoplastic breast surgery exists between older and younger women, and to explore the underlying reasons for this., Methods: A literature search was conducted on 17 January 2022 using MEDLINE and Embase. Eligible studies comprised full-text articles of patients who underwent oncoplastic breast surgery for primary invasive breast cancer, and included those aged at least 65 years., Results: Ten published studies were identified. One study was ranked as providing level 2 evidence, and the remainder were level 3. A total of 567 women underwent oncoplastic breast surgery for primary breast cancer, of whom only 61 (10.8 per cent) were aged 65 years or older. None of the studies directly compared younger with older women, or explored the underlying factors contributing to this discrepancy in uptake., Conclusion: This review has demonstrated a lower uptake of oncoplastic breast surgery in older compared with younger women. Given the increasing number of older women living with breast cancer who may be eligible for breast-conserving surgery, further research into this area is required., (© The Author(s) 2023.

Background: Postoperative complications may activate prometastatic systemic pathways through tissue damage, wound healing, infection, and inflammation. Postoperative complications are associated with inferior survival in several types of cancer. The aim was to determine the association between postoperative complications and survival in breast cancer., Methods: This population-based cohort included women operated for T1-3 N0-3 M0 invasive breast cancer in Sweden from 2008 to 2017. Only major surgical postoperative complications leading to readmission and/or reoperation within 30 days were considered. Main outcomes were overall survival (OS) and breast cancer-specific survival (BCSS). Prospectively collected nationwide register data were used. Multivariable Cox models were adjusted for clinical and socioeconomic confounders and co-morbidity., Results: Among 57 152 women, major surgical postoperative complications were registered for 1854 patients. Median follow-up was 6.22 (0.09-11.70) years. Overall, 9163 patients died, and 3472 died from breast cancer. Major surgical postoperative complications were more common after mastectomy with or without immediate reconstruction (7.3 and 4.3 per cent respectively) than after breast-conserving surgery (2.3 per cent). Unadjusted 5-year OS and BCSS rates were 82.6 (95 per cent c.i. 80.8 to 84.5) and 92.1 (90.8 to 93.5) per cent respectively for women with a major surgical postoperative complication, and 88.8 (88.6 to 89.1) and 95.0 (94.8 to 95.2) per cent for those without a complication (P < 0.001). After adjustment, all-cause and breast cancer mortality rates remained higher after a major surgical postoperative complication (OS: HR 1.32, 95 per cent c.i. 1.15 to 1.51; BCSS: HR 1.31, 1.04 to 1.65). After stratification for type of breast surgery, this association remained significant only for women who had mastectomy without reconstruction (OS: HR 1.41, 1.20 to 1.66; BCSS: HR 1.36, 1.03 to 1.79)., Conclusion: Major surgical postoperative complications are associated with inferior survival, especially after mastectomy. These results underline the importance of surgical de-escalation., (© The Author(s) 2022. Published by Oxford University Press on behalf of BJS Society Ltd.)

Background: Reduction of positive margin rate (PMR) in breast-conserving surgery (BCS) of non-palpable breast cancer remains a challenge. The efficacy of intraoperative specimen radiography (SR) is unclear. This randomized trial evaluated whether the PMR was reduced by the use of devices that allow precise localization of the affected margins., Methods: Patients with microcalcification-associated breast cancer undergoing planned BCS were enrolled. Study participants were randomized to receive either SR with radiopaque tissue transfer and X-ray system (KliniTrayTM) or the institutional standard procedure (ISO). In all patients with a radiological margin less than 5 mm, an immediate re-excision was conducted. The primary outcome was the PMR. Risk factors for positive margins and the effect of immediate re-excision on final surgery were secondary analyses., Results: Among 122 randomized patients, 5 patients were excluded due to the extent of primary surgery and 117 were available for analysis. Final histopathology revealed a PMR of 31.7 per cent for the KliniTrayTM group and 26.3 per cent for the ISO group (P = 0.127). Independent factors for positive margins were histological tumour size more than 30 mm (adjusted OR (aOR) 10.73; 95 per cent c.i. 3.14 to 36.75; P < 0.001) and specimen size more than 50 mm (aOR 6.65; 95 per cent c.i. 2.00 to 22.08; P = 0.002). Immediate re-excision due to positive SR led to an absolute risk reduction in positive margins of 13.6 per cent (from 42.7 to 29.1 per cent)., Conclusion: Specimen orientation with a radiopaque tissue transfer and X-ray system did not decrease the PMR in patients with microcalcification-associated breast cancer; however, SR and immediate re-excision proved to be helpful in the reduction of PMR., Registration Number: DRKS00011527 (https://www.drks.de)., (© The Author(s) 2022.

Background: Following therapeutic mammoplasty (TM), the contralateral breast may require a later balancing procedure to optimize shape and symmetry. The alternative is to offer patients simultaneous TM with immediate contralateral symmetrization via a dual-surgeon approach, with the goal of reducing costs and minimizing the number of subsequent hospital appointments in an era of COVID-19 surges. The aim of this cost-consequence analysis is to characterize the cost-benefit of immediate bilateral symmetrization dual-operator mammoplasty versus staged unilateral single operator for breast cancer surgery., Method: A prospective single-centre observational study was conducted at an academic teaching centre for breast cancer surgery in the UK. Pseudonymized data for clinicopathological variables and procedural care information, including the type of initial breast-conserving surgery and subsequent reoperation(s), were extracted from the electronic patient record. Financial data were retrieved using the Patient-Level Information and Costing Systems., Results: Between April 2014 and March 2020, 232 women received either immediate bilateral (n = 44), staged unilateral (n = 57) for breast cancer, or unilateral mammoplasty alone (n = 131). The median (interquartile range (i.q.r.)) additional cost of unilateral mammoplasty with staged versus immediate bilateral mammoplasty was €5500 (€4330 to €6570) per patient (P < 0.001), which represents a total supplementary financial burden of €313 462 to the study institution. There was no significant difference between groups in age, Charlson comorbidity index, operating minutes, time to adjuvant radiotherapy in months, or duration of hospital stay., Conclusion: Synchronous dual-surgeon immediate bilateral TM can deliver safe immediate symmetrization and is financially beneficial, without delay to receipt of adjuvant therapy, or additional postoperative morbidity., (© The Author(s) 2022.

Background: Wire localization is historically the most common method for guiding excision of non-palpable breast lesions, but there are limitations to the technique. Newer technologies such as magnetic seeds may allow some of these challenges to be overcome. The aim was to compare safety and effectiveness of wire and magnetic seed localization techniques., Methods: Women undergoing standard wire or magnetic seed localization for non-palpable lesions between August 2018 and August 2020 were recruited prospectively to this IDEAL stage 2a/2b platform cohort study. The primary outcome was effectiveness defined as accurate localization and removal of the index lesion. Secondary endpoints included safety, specimen weight and reoperation rate for positive margins., Results: Data were accrued from 2300 patients in 35 units; 2116 having unifocal, unilateral breast lesion localization. Identification of the index lesion in magnetic-seed-guided (946 patients) and wire-guided excisions (1170 patients) was 99.8 versus 99.1 per cent (P = 0.048). There was no difference in overall complication rate. For a subset of patients having a single lumpectomy only for lesions less than 50 mm (1746 patients), there was no difference in median closest margin (2 mm versus 2 mm, P = 0.342), re-excision rate (12 versus 13 per cent, P = 0.574) and specimen weight in relation to lesion size (0.15 g/mm2versus 0.138 g/mm2, P = 0.453)., Conclusion: Magnetic seed localization demonstrated similar safety and effectiveness to those of wire localization. This study has established a robust platform for the comparative evaluation of new localization devices., (© The Author(s) 2022. Published by Oxford University Press on behalf of BJS Society Ltd.)

Background: There is a transition from wire-guided localization (WGL) of non-palpable breast cancer to other localization techniques. Multiple prospective studies have sought to establish superior clinical outcomes for radioactive-seed localization (RSL), but consistent and congruent evidence is missing., Methods: In this study, female patients with breast cancer operated with breast-conserving surgery after tumour localization of a non-palpable breast cancer or ductal carcinoma in situ (DCIS) were included. The cohort was identified from the nationwide Netherlands Breast Cancer Audit conducted between 2013 and 2018. Trends in localization techniques were analysed. Univariable and multivariable analyses were performed to assess the association between the localization technique and the probability of a reoperation., Results: A total of 28 370 patients were included in the study cohort. The use of RSL increased from 15.7 to 61.1 per cent during the study years, while WGL decreased from 75.4 to 31.6 per cent. The localization technique used (RSL versus WGL) was not significantly associated with the odds of a reoperation, regardless of whether the lesion was DCIS (odds ratio 0.96 (95 per cent c.i. 0.89 to 1.03; P = 0.281)) or invasive breast cancer (OR 1.02 (95 per cent c.i. 0.96 to 1.10; P = 0.518))., Conclusion: RSL is rapidly replacing WGL as the preoperative localization technique in breast surgery. This large nationwide registry study found no association between the type of localization technique and the odds of having a reoperation, thus confirming the results of previous prospective cohort studies., (© The Author(s) 2021.

Background: Future innovations in science and technology with an impact on multimodal breast cancer management from a surgical perspective are discussed in this narrative review. The work was undertaken in response to the Commission on the Future of Surgery project initiated by the Royal College of Surgeons of England., Methods: Expert opinion was sought around themes of surgical de-escalation, reduction in treatment morbidities, and improving the accuracy of breast-conserving surgery in terms of margin status. There was emphasis on how the primacy of surgical excision in an era of oncoplastic and reconstructive surgery is increasingly being challenged, with more effective systemic therapies that target residual disease burden, and permit response-adapted approaches to both breast and axillary surgery., Results: Technologies for intraoperative margin assessment can potentially half re-excision rates after breast-conserving surgery, and sentinel lymph node biopsy will become a therapeutic procedure for many patients with node-positive disease treated either with surgery or chemotherapy as the primary modality. Genomic profiling of tumours can aid in the selection of patients for neoadjuvant and adjuvant therapies as well as prevention strategies. Molecular subtypes are predictive of response to induction therapies and reductive approaches to surgery in the breast or axilla., Conclusion: Treatments are increasingly being tailored and based on improved understanding of tumour biology and relevant biomarkers to determine absolute benefit and permit delivery of cost-effective healthcare. Patient involvement is crucial for breast cancer studies to ensure relevance and outcome measures that are objective, meaningful, and patient-centred., (© The Author(s) 2021.

Background: In patients with triple-negative breast cancer (TNBC), oncological and survival outcomes based on locoregional treatment are poorly understood. In particular, the safety of breast-conserving surgery (BCS) for TNBC has been questioned., Methods: A meta-analysis was performed to evaluate locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) rates in patients with TNBC who had breast-conserving surgery versus mastectomy. Estimates were pooled in random-effects analysis. The effect of study-level co-variables was assessed by univariable metaregression., Results: Fourteen studies, including 19 819 patients operated for TNBC met the inclusion criteria; 9828 patients (49.6 per cent) underwent BCS and 9991 (50.4 per cent) had a mastectomy. Patients with smaller tumours were more likely to be selected for BCS (pooled odds ratio (OR) for T1 tumours 1.95, 95 per cent c.i. 1.64 to 2.32; P < 0.001). The pooled OR for LRR was 0.64 (0.48 to 0.85; P = 0.002), indicating a statistically significantly lower odds of LRR among women who had BCS relative to mastectomy. The pooled OR for DM was 0.70 (0.53 to 0.94; P = 0.02), indicating a lower odds of DM among women who had BCS; however, this difference diminished with increasing study-level age and follow-up time. A pooled hazard ratio of 0.78 (0.69 to 0.89; P < 0.001) showed a significantly lower hazard for all-cause mortality among women undergoing BCS versus mastectomy., Conclusion: These results should be interpreted cautiously owing to likely differences in selection for BCS or mastectomy in the included studies. Patients with TNBC selected for BCS do not, however, have a worse prognosis than those treated with mastectomy, and breast conservation can be offered when feasible clinically., (© The Author(s) 2021.

Background: The aim was to determine the cost-effectiveness of radioguided occult lesion localization using 125I-labelled seeds (125I seeds) versus hookwire localization in terms of incremental cost per reoperation avoided for women with non-palpable breast cancer undergoing breast-conserving surgery., Methods: This study was based on a multicentre RCT with eight study sites comprising seven public hospitals and one private hospital. An Australian public health system perspective was taken. The primary effectiveness outcome for this study was reoperations avoided. Cost-effectiveness was expressed as an incremental cost-effectiveness ratio (ICER). One-way and probabilistic sensitivity analyses were used to explore uncertainty. The willingness to pay (additional cost of localization using 125I seeds justified by reoperation cost avoided) was set at the weighted, top-down cost of reoperation. Costs were in 2019 Australian dollars ($1 was equivalent to €0.62)., Results: The reoperation rate was 13.9 (95 per cent confidence interval 10.7 to 18.0) per cent for the 125I seed group and 18.9 (14.8 to 23.8) per cent for the hookwire localization group. The ICER for 125I seed versus hookwire localization was $4474 per reoperation averted. The results were most sensitive to uncertainty around the probability of reoperation. Accounting for transition probability and cost uncertainty for 125I seed localization, there was a 77 per cent probability that using 125I seeds would be cost-effective, with a willingness to pay of $7693 per reoperation averted., Conclusion: Radioguided occult lesion localization using 125I seeds is likely to be cost-effective, because the marginal (additional) cost compared with hookwire localization is less than the cost of reoperations avoided., (© The Author(s) 2021.

Background: Previous studies have suggested improved efficiency and patient outcomes with 125I seed compared with hookwire localization (HWL) in breast-conserving surgery, but high-level evidence of superior surgical outcomes is lacking. The aim of this multicentre pragmatic RCT was to compare re-excision and positive margin rates after localization using 125I seed or hookwire in women with non-palpable breast cancer., Methods: Between September 2013 and March 2018, women with non-palpable breast cancer eligible for breast-conserving surgery were assigned randomly to preoperative localization using 125I seeds or hookwires. Randomization was stratified by lesion type (pure ductal carcinoma in situ (DCIS) or other) and study site. Primary endpoints were rates of re-excision and margin positivity. Secondary endpoints were resection volumes and weights., Results: A total of 690 women were randomized at eight sites; 659 women remained after withdrawal (125I seed, 327; HWL, 332). Mean age was 60.3 years in the 125I seed group and 60.7 years in the HWL group, with no difference between the groups in preoperative lesion size (mean 13.2 mm). Lesions were pure DCIS in 25.9 per cent. The most common radiological lesion types were masses (46.9 per cent) and calcifications (28.2 per cent). The localization modality was ultrasonography in 65.5 per cent and mammography in 33.7 per cent. The re-excision rate after 125I seed localization was significantly lower than for HWL (13.9 versus 18.9 per cent respectively; P = 0.019). There were no significant differences in positive margin rates, or in specimen weights and volumes., Conclusion: Re-excision rates after breast-conserving surgery were significantly lower after 125I seed localization compared with HWL.

Background: Oncoplastic techniques in breast-conserving surgery (BCS) are used increasingly for larger tumours. This large cohort study aimed to assess oncological outcomes after oncoplastic BCS (OPS) versus standard BCS., Methods: Data for all women who had BCS in three centres in Stockholm during 2010-2016 were extracted from the Swedish National Breast Cancer Register. All patients with T2-3 tumours, all those receiving neoadjuvant treatment, and an additional random sample of women with T1 tumours were selected. Medical charts were reviewed for local recurrences and surgical technique according to the Hoffman-Wallwiener classification. Date and cause of death were retrieved from the Swedish Cause of Death Register., Results: The final cohort of 4178 breast cancers in 4135 patients was categorized into three groups according to surgical technique: 3720 for standard BCS, 243 simple OPS, and 215 complex OPS. Median duration of follow up was 64 (range 24-110) months. Node-positive and large tumours were more common in OPS than in standard BCS (P < 0.001). There were 61 local recurrences: 57 (1.5 per cent), 1 (0.4 per cent) and 3 (1.4 per cent) in the standard BCS, simple OPS and complex OPS groups respectively (P = 0.368). Overall, 297 patients died, with an unadjusted 5-year overall survival rate of 94.7, 93.1 and 92.6 per cent respectively (P = 0.350). Some 102 deaths were from breast cancer, with unadjusted 5-year cancer-specific survival rates of 97.9, 98.3 and 95.0 per cent respectively (P = 0.056)., Discussion: Oncoplastic BCS is a safe surgical option, even for larger node-positive tumours, with low recurrence and excellent survival rates., (© The Author(s) 2021.

Accelerated partial breast irradiation (APBI) delivers a short course of adjuvant RT after breast conserving surgery to only a limited part of the breast where the tumor was located. This procedure requires expertise, good communication, and close collaboration between specialized surgeons and attending radiation oncologists with adequate intraoperative tumor bed clip marking. However, APBI offers several intrinsic benefits when compared with whole breast irradiation (WBIR) including reduced treatment time (1 versus 4-6 weeks) and better sparing of surrounding healthy tissues. The present publication reviews the APBI level 1-evidence provided with various radiation techniques supplemented by long-term experience obtained from large multi-institutional phase II studies. Additionally, it offers an outlook on recent research with ultra-short or single-fraction APBI courses and new brachytherapy sources. Mature data from three randomized controlled trials (RCTs) clearly prove the noninferiority of APBI with 'only two techniques-1/MIBT (multicatheter interstitial brachytherapy) (two trials) and 2/intensity modulated radiotherapy (one trial)'-in terms of equivalent local control/overall survival to the previous standard 'conventionally fractionated WBIR'. However, MIBT-APBI techniques were superior in both toxicity and patient-reported outcomes (PROs) versus WBIR at long-term follow-up. Currently, in RCT-setting, alternative APBI techniques such as intraoperative electrons, 50-kV x-rays and three-dimensional conformal external beam radiotherapy (3D-CRT) failed to demonstrate noninferiority to conventionally fractionated WBIR. However, 3D-CRT-APBI compared noninferior to hypo-fractionated WBIR in preventing ipsilateral breast tumor recurrence (randomized RAPID-trial) but was associated with a higher rate of late radiation toxicity. Ultimately, MIBT remains the only APBI modality with noninferior survival/superior toxicity/PROs at 10-years and therefore should be prioritized over alternative methods in patients with breast cancer considered at low-risk for local recurrence according to recent international guidelines., (© The Author(s) 2020.

Although phase III trials have been published comparing whole breast irradiation (WBI) with accelerated partial breast irradiation (APBI) using intraoperative radiotherapy (IORT), long-term follow-up results are lacking. We report the 10-year follow-up results of a prospective phase I/II clinical trial of IORT. The inclusion criteria were as follows: (i) tumor size <2.5 cm, (ii) desire for breast-conserving surgery, (iii) age >50 years, (iv) negative margins after resection and (v) sentinel lymph node-negative disease. A single dose of IORT (19-21 Gy) was delivered to the tumor bed in the operation room just after wide local excision of the primary breast cancer using a 6-12 MeV electron beam. Local recurrence was defined as recurrence or new disease within the treated breast and was evaluated annually using mammography and ultrasonography. A total of 32 patients were eligible for evaluation. The median patient age was 65 years and the median follow-up time was 10 years. Two patients experienced local recurrence just under the nipple, out of the irradiated field, after 8 years of follow-up. Three patients had contralateral breast cancer and one patient experienced bone metastasis after 10 years of follow-up. No patient experienced in-field recurrence nor breast cancer death. Eight patients had hypertrophic scarring at the last follow-up. There were no lung or heart adverse effects. This is the first report of 10-year follow-up results of IORT as APBI. The findings suggest that breast cancer with extended intraductal components should be treated with great caution., (© The Author(s) 2020.

Many patients with positive margins following breast-conserving surgery (BCS) undergo re-excisions that aim to remove residual disease from the breast, which brings a tremendous emotional burden in addition to financial consequences. We sought to determine whether re-excisions could be safely avoided without compromising local control and survival by using whole-breast radiation therapy (WBRT) with a tumor bed boost in patients with early-stage breast cancer with focally positive, tumor-exposed margins after BCS. All patients with ductal carcinoma in situ (DCIS) and/or invasive breast cancer (IBC) who had pathologically tumor-exposed margins following BCS, without re-excision and treated with WBRT with tumor bed boost between March 2005 and December 2011, were included. The radiotherapy consisted of WBRT at a dose of 50 Gy in 25 fractions, followed by a tumor bed boost with an additional dose of 16 Gy in eight fractions. A total of 125 patients fulfilled the eligibility criteria; of the 125 patients, 1 had bilateral breast cancer, resulting in 126 cases. Invasive disease was found in 102 (81%) cases and purely ductal carcinoma in situ (DCIS) disease in 24 (19%) cases. The 10-year ipsilateral breast tumor recurrence (IBTR) -free survival, progression-free survival (PFS), and 10-year overall survival (OS) rates were 95%, 92.5% and 96%, respectively. Patients with early-stage breast cancer who receive BCS and have focally positive, tumor-exposed margins can avoid re-excision by undergoing WBRT followed by a sufficient dose of tumor bed boost, without negatively impacting local control and survival., (© The Author(s) 2020.

Deep inspiration breath hold (DIBH) is a common method used worldwide for reducing the radiation dose to the heart. However, few studies have reported on the relationship between dose reduction and patient-specific parameters. The aim of this study was to compare the reductions of heart dose and volume using DIBH with the dose/volume of free breathing (FB) for patients with left-sided breast cancer and to analyse patient-specific dose reduction parameters. A total of 85 Asian patients who underwent whole-breast radiotherapy after breast-conserving surgery were recruited. Treatment plans for FB and DIBH were retrospectively generated by using an automated breast planning tool with a two-field tangential intensity-modulated radiation therapy technique. The prescribed dose was 50 Gy in 25 fractions. The dosimetric parameters (e.g., mean dose and maximum dose) in heart and lung were extracted from the dose-volume histogram. The relationships between dose-volume data and patient-specific parameters, such as age, body mass index (BMI), and inspiratory volume, were analyzed. The mean heart doses for the FB and DIBH plans were 1.56 Gy and 0.75 Gy, respectively, a relative reduction of 47%. There were significant differences in all heart dosimetric parameters (p < 0.001). For patients with a high heart dose in the FB plan, a relative reduction of the mean heart dose correlated with inspiratory volume (r = 0.646). There was correlation between the relative reduction of mean heart dose and BMI (r = -0.248). We recommend considering the possible feasibility of DIBH in low BMI patients because the degree of benefit from DIBH varied with BMI., (© The Author(s) 2020.

In 2013, the American Society for Radiation Oncology recommended against the routine use of intensity-modulated radiation therapy (IMRT) in breast cancer patients. We evaluated trends in the use of IMRT before and after the release of the recommendation. Using Surveillance, Epidemiology, and End Results Medicare data, we identified 13 457 breast cancer patients diagnosed between 2012 and 2015 who received breast-conserving surgery and postsurgery, whole-breast, IMRT, or three-dimensional conformal radiotherapy. We find that the use of IMRT decreased by 4.6 (95% confidence interval [CI] = 3.6 to 5.6; two-sided P < .001) percentage points in hospital-based clinics. In freestanding radiotherapy clinics, which had baseline rates of IMRT use that were more than 20 percentage points higher than in hospital-based clinics, use of IMRT declined by 6.1 (95% CI = 3.5 to 8.7; two-sided P < .001) percentage points. Use of IMRT declined following the release of the recommendation, but a large share of patients treated in freestanding clinics continue to receive IMRT., (© The Author(s) 2019.

Background: High rates of reoperation following breast-conserving surgery (BCS) for positive margins are associated with costs to healthcare providers. The aim was to assess the quality of evidence on reported re-excision costs and compare the direct patient-level costs between patients undergoing successful BCS versus reoperations after BCS., Methods: The study used data from women who had BCS with or without reoperation at a single institution between April 2015 and March 2016. A systematic review of health economic analysis in BCS was conducted and scored using the Quality of Health Economic Studies (QHES) instrument. Financial data were retrieved using the Patient-Level Information and Costing Systems (PLICS) for patients. Exchange rates used were: US $1 = £0·75, £1 = €1·14 and US $1 = €0·85., Results: The median QHES score was 47 (i.q.r. 32·5-79). Only two of nine studies scored in the upper QHES quartile (score at least 75). Costs of initial lumpectomy and reoperation were in the range US $1234-11786 and $655-9136 respectively. Over a 12-month interval, 153 patients had definitive BCS and 59 patients underwent reoperation. The median cost of reoperations after BCS (59 patients) was £4511 (range 1752-18 019), representing an additional £2136 per patient compared with BCS without reoperation (P < 0·001)., Conclusion: The systematic review demonstrated variation in methodological approach to cost estimates and a paucity of high-quality cost estimate studies for reoperations. Extrapolating local PLICS data to a national level suggests that getting BCS right first time could result in substantial savings., (© 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.)

Background: Breast-conserving treatment (BCT) for breast cancer can lead to deformation of the treated breast, resulting in patient dissatisfaction with the final cosmetic outcome. Currently, literature on the specific information needs of patients concerning the cosmetic effects of BCT is lacking. The aim of the present study was to investigate the information needs of breast cancer patients regarding the long-term cosmetic outcome after BCT., Subjects, Materials, and Methods: The data from 115 women who had undergone BCT in a general teaching hospital breast cancer unit in The Netherlands were studied. Structured questionnaires and semi-structured interviews were conducted between October 2012 and April 2013. A mixed model of quantitative and qualitative research was used to explore patient-reported information needs. A phenomenological approach was used to analyze the qualitative data., Results: This study shows that women undergoing BCT want to discuss long-term cosmetic effects. Most patients appreciate such information immediately after the diagnosis. Patients indicated that it is also important to pay attention to the cosmetic effects during the follow-up visits, because deformation of the breast can also occur at a later stage. Furthermore, half the patients indicated that they would not likely raise the subject of cosmetic effects of the treatment themselves., Conclusion: Breast cancer patients have a need for long-term attention for cosmetic outcome of BCT, which should be tailored during the treatment and follow-up process., Implications for Practice: Currently, no literature exists concerning patients' needs for information regarding the cosmetic effects of breast-conserving therapy (BCT). Bringing up the cosmetic effects of BCT by health care professionals does not appear to be a standard part of treatment and follow-up. It is expected that the quality of care and life will be improved by providing information and guidance regarding the cosmetic outcome of BCT within the existing structure of the breast cancer pathway. Discussion and visualization of the cosmetic effects prior to treatment will lead to more realistic expectations, and as a result, secondary interventions, such as partial prostheses and plastic surgery, may be easier to discuss and accept., Competing Interests: Disclosures of potential conflicts of interest may be found at the end of this article., (© AlphaMed Press 2018.)

Background: Society of Surgical Oncology and American Society for Radiation Oncology guidelines define clear margins in breast-conserving therapy (BCT) as 'no ink on tumour', in contrast to the attainment of margins of at least 1 mm widely practised in the UK. The primary aim of this study was to explore clinical, surgical and tumour-related factors associated with local recurrence after BCT, with a secondary aim of assessing the impact of margin re-excision on the risk of local recurrence., Methods: Patient demographics, surgical details, tumour characteristics and local recurrence were recorded for consecutive women with BCT undergoing surgery between January 1997 and January 2007. Margins were defined as clear (greater than 1 mm), close (less than 1 mm but no ink on tumour), reaches (ink on tumour) and clear after re-excision., Results: A total of 1045 women of median age 54 (range 18-86) years were studied. Median follow-up was 89 (range 4-196) months. Local recurrence occurred in 52 patients (5·0 per cent). Ink on tumour was associated with local recurrence (hazard ratio (HR) 4·86, 95 per cent c.i. 1·49 to 15·79; P  = 0·009). Risk of local recurrence was the same for close and clear margins (HR 1·03, 0·40 to 2·62; P  = 0·954). In women with involved margins, re-excision was still associated with an increased local recurrence risk (HR 2·50, 1·32 to 4·72; P  = 0·005). Oestrogen receptor negativity increased risk (HR 2·28, 1·28 to 4·06; P  = 0·005)., Conclusion: Adequately excised margins, even when under 1 mm, provide equivalent outcomes to wider margins in BCT. Achieving complete excision at primary surgery achieves the lowest rates of local recurrence.

Background: The prognostic equivalence between mastectomy and breast-conserving surgery (BCS) followed by radiotherapy was shown in pivotal trials conducted decades ago. Since then, detection and treatment of breast cancer have improved substantially and recent retrospective analyses point towards a survival benefit for less extensive breast surgery. Evidence for the association of such survival data with locoregional recurrence rates is largely lacking., Methods: The Swedish Multicentre Cohort Study prospectively included clinically node-negative patients with breast cancer who had planned sentinel node biopsy between 2000 and 2004. Axillary lymph node dissection was undertaken only in patients with sentinel node metastases. For the present investigation, adjusted survival analyses were used to compare patients who underwent BCS and postoperative radiotherapy with those who received mastectomy without radiotherapy., Results: Of 3518 patients in the Swedish Multicentre Cohort Study, 2767 were included in the present analysis; 2338 had BCS with postoperative radiotherapy and 429 had mastectomy without radiotherapy. Median follow-up was 156 months. BCS followed by whole-breast irradiation was superior to mastectomy without irradiation in terms of both overall survival (79·5 versus 64·3 per cent respectively at 13 years; P < 0·001) and breast cancer-specific survival (90·5 versus 84·0 per cent at 13 years; P < 0·001). The local recurrence rate did not differ between the two groups. The axillary recurrence-free survival rate at 13 years was significantly lower after mastectomy without irradiation (98·3 versus 96·2 per cent; P < 0·001)., Conclusion: The present data support the superiority of BCS with postoperative radiotherapy over mastectomy without radiotherapy. The axillary recurrence rate differed significantly, and could be one contributing factor in a complex explanatory model., (© 2018 The Authors.

Background: The application of heparinoid moisturizer for 2 weeks following whole-breast radiotherapy (WBRT) was previously reported to significantly increase skin water content (WC) and help improve skin dryness and desquamation. The prospective open-label, randomized trial included an exploratory arm to investigate the preventive efficacy of heparinoid moisturizer for acute radiation dermatitis (ARD)., Methods: Between April 2011 and April 2013, patients receiving WBRT were assigned (1:2:2) to receive either: moisturizer for prophylaxis (group P), moisturizer starting 2 weeks after WBRT for treatment (group M), and no moisturizer (group C). This paper presents the results of comparison between the exploratory arm and no moisturizer group. Skin WC was measured prior to WBRT, on the last day of WBRT, and 2 weeks, 4 weeks and 3 months following WBRT. Signs and symptoms were also assessed., Results: Comparing two groups, WC values were significantly higher in group P until 4 weeks following WBRT. At 2 weeks following WBRT, mean WC values in group P and C were 38.5 ± 6.1 arbitrary units (a.u.) and 30.2 ± 7.8 a.u., respectively (P < 0.001). In group C, dryness was more severe at 2 and 4 weeks following WBRT and desquamation more severe until 3 months following WBRT. However, the erythema score showed no difference between the two groups. Regarding symptoms, group C pain scores on the last day of WBRT were significantly higher than in group P (P < 0.030)., Conclusions: The preventive application of heparinoid moisturizer has the potential of reducing skin desquamation and dryness in patients receiving WBRT.

Background: Neoadjuvant therapy (NAT) for operable breast cancer may facilitate more breast-conserving surgery (BCS). It seems, however, that this benefit is not being realized fully., Methods: A systematic review of the literature was performed. RCTs were included. The criteria for inclusion were: documentation of surgical assessment before and after NAT, surgery performed (BCS or mastectomy), and clinical and pathological responses., Results: A total of 1452 patients from seven RCTs met the inclusion criteria. After NAT, the feasibility of BCS increased from 43·3 to 60·4 per cent (P < 0·001), but BCS was performed in only 51·8 per cent (P = 0·04). Only 31 per cent of patients who became eligible for BCS (assessed on clinical response) underwent BCS (pooled rate ratio 0·31, 95 per cent c.i. 0·22 to 0·44; P < 0·001). Of the mastectomy candidates who achieved a pathological complete response after NAT, only 41 per cent underwent BCS (pooled rate ratio 0·41, 0·23 to 0·74; P = 0·003). The main factors that influenced the decision not to shift to BCS, even though it was feasible, were clinical assessment before NAT, multicentricity and tumour size at presentation., Conclusion: Breast surgery performed after NAT does not reflect tumour response, resulting in potentially unnecessary radical surgery, especially mastectomy. The barriers to maximizing the surgical benefits of NAT need to be better understood and explored., (© 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.)

Background: Breast cancer is the most common female malignancy worldwide. The aim of this study was to investigate the influence of surgical procedures and quality-of-care (QoC) on quality-of-life (QoL) among breast cancer survivors who underwent breast-conserving therapy (BCT) or mastectomy, and to identify provider- and patient-related factors pertaining to QoL., Method: In this cross-sectional study, structured-questionnaires were distributed among breast cancer survivors in 19 hospitals. QoL was evaluated using the European Organization for Research and Treatment of Cancer core questionnaire (EORTC QLQ-C30) and the breast cancer specific module (EORTC QLQ-BR23). QoC is indicated by adherence to the core measures stipulated for the treatment of breast cancer. Multiple regression and hierarchical linear modeling were used for multivariate analysis., Results: A total of 544 female survivors of Stage 0-III breast cancer were included, among whom 217 (39.9%) underwent BCT and 327 (60.1%) underwent mastectomy. Surgical modality does not appear to have a notable impact on any QoL domains except body image; i.e. patients who underwent BCT reported better body image (diff = 11.20, P < 0.001), particularly at 1-5 years after the initial treatment. Independent factors including age, education, employment, marital status, income, chemotherapy, duration since treatment, recurrence status, primary hospital accreditation level and location all appear to be correlated to QoL., Conclusion: Patients with breast cancer should be informed of differences in QoL when discussing treatment options. Furthermore, physicians should recognize that the impact of surgical treatment modality on QoL may vary according to patients' sociodemographic and clinical characteristics., (© The Author 2017.

Background: Breast-conserving surgery for isolated non-palpable ductal carcinoma in situ (DCIS) is associated with high rates of incomplete surgical resection in comparison with unifocal invasive breast cancer. Therefore, accurate preoperative localization of the lesion is very important to facilitate adequate resection. Wire-guided localization (WGL) remains the standard for localization of DCIS. Recently, iodine-125 seed-guided localization (I-125 GL) was introduced as an alternative localization technique. The aim of this study was to compare the efficacy of these localization techniques in the resection of DCIS by breast-conserving surgery., Methods: Between March 2006 and June 2013, 169 patients with non-palpable DCIS were treated with breast-conserving surgery. Only patients with pure DCIS on both preoperative core biopsy and definitive pathology were included., Results: WGL was performed in 78 patients and I-125 GL in 91 patients. The groups did not differ with respect to age, size of DCIS or type of imaging used. Patients in the I-125 GL group had a significantly lower risk of extensively involved resection margins than those in the WGL group (4 versus 13 per cent respectively; P = 0·048)., Conclusion: In patients treated with breast-conserving surgery for non-palpable DCIS, localization with iodine-125 seeds is superior to the WGL technique in reducing the risk of extensively involved resection margins., (© 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.)

Background: Incidence rates of breast cancer continue to rise in the People's Republic of China. The purpose of this study was to describe Chinese trends in radical surgical modalities and influential imaging and demographic factors for breast malignancies., Materials and Methods: This study was a hospital-based, multicenter, 10-year (1999-2008), retrospective study. Descriptive statistical tests were used to illustrate information regarding radical surgical trends for the treatment of breast malignancies. Chi-square tests were used to assess effect of demographic factors in addition to imaging and pathological data on the specific surgical method., Results: A total of 4,211 patients were enrolled in the survey. Among them, 3,335 patients with stage 0 to stage III disease undergoing mastectomy or breast-conserving surgery (BCS) were included in the final analysis. The rate of BCS increased from 1.53% in 1999 to 11.88% in 2008. The rate of mastectomy declined over this time period, from 98.47% in 1999 to 88.12% in 2008, with increasing use of diagnostic imaging methods and pathological biopsies. A significantly greater percentage of patients with office work, high education levels, unmarried status, younger age, and early pathological stages preferred BCS compared with mastectomy., Conclusion: Rates of mastectomy in China remain elevated due to diagnosis at higher stages; however, because of increased use of diagnostic imaging, improvement of biopsy methods, and patient education, rates of less invasive lumpectomy are increasing and rates of mastectomy have decreased in China., Implications for Practice: In this study, 4,211 cases were collected from 1999 to 2008 through a multicenter retrospective study of varying geographic and socioeconomic areas to illustrate trends of surgeries in the People's Republic of China. The correlations between demographic and tumor characteristics and among methods of surgical treatment were explored. This study shows that the rate of breast-conserving surgery (BCS) increased and the rate of mastectomy declined over this time period with increasing use of diagnostic imaging methods and pathological biopsies. Patients with office work, high education levels, unmarried status, younger age, and early pathological stages preferred BCS compared with mastectomy in China., (©AlphaMed Press.)

The increasing use of chemotherapy before surgery has affected a number of local-regional treatment decisions including surgical and radiation management of the breast, management of axillary lymph nodes, and the indications for postmastectomy radiation. In this monograph, we will focus on surgical and radiation management as components of breast conservation therapy. The early randomized trials that compared neoadjuvant to adjuvant chemotherapy in breast cancer demonstrated that rates of breast conservation can be increased when chemotherapy is sequenced first. This was a direct consequence of high response rates seen with neoadjuvant treatment, which permitted downstaging of a large primary tumor to a volume that permitted breast-conserving surgery. Some initial studies found higher rates of breast recurrences with this approach but over time, with improved multidisciplinary coordination and proper patient selection, rates of breast recurrences have improved to the excellent levels achieved when surgery is performed first. New clinical trials are also ongoing to define the role of sentinel lymph node surgery and regional lymph node radiation., (© The Author 2015. Published by Oxford University Press.

Neoadjuvant chemotherapy has several appealing potential benefits compared with classic adjuvant chemotherapy. Of these, the only proven benefit is to facilitate the surgical approach, either by converting an inoperable cancer to one that is operable, or by converting a patient who is felt to be a candidate for mastectomy to one who might be treated successfully with breast conserving therapy. Randomized trials comparing neoadjuvant chemotherapy with postoperative chemotherapy have failed to demonstrate prolongation of overall survival. The benefits of monitoring apparent response during neoadjuvant chemotherapy have not been proven. Conduct of phase II drug development trials in the neoadjuvant setting may be advantageous compared with performing such trials in the metastatic setting. However, such trials raise concerns that are not unavoidable but need to be addressed., (© The Author 2015. Published by Oxford University Press. All rights reserved.

Radiotherapy (RT) is standard following neoadjuvant chemotherapy (NCT) and breast-conserving surgery. NCT leads to pathologic down-staging, allowing some patients to undergo breast-conserving therapy (BCT) instead of mastectomy. BCT can also be considered in select stage III patients who respond well to NCT. Clearly-negative surgical margins should be obtained in all patients undergoing BCT. RT is used selectively following NCT and mastectomy. Indications for RT have not been fully established; retrospective data and results from National Surgical Adjuvant Breast and Bowel Project B-18 and B-27 currently form the basis for recommending RT. Patients with locally advanced breast cancer should receive postmastectomy RT (PMRT). Patients with residual nodal involvement require PMRT. Stage I-II patients with a pathologic complete response do not require PMRT. Patients without residual nodal involvement, but with residual breast involvement represent an intermediate-risk group. NCT also provides down-staging in the axilla. The role of axillary RT in the setting of NCT is under investigation in ongoing randomized trials., (© The Author 2015.

Background: The recommendations of the UK All Party Parliamentary Group on Breast Cancer (2013) have been endorsed recently by the UK Association of Breast Surgeons and are in line with the 2007 Cancer Reform Strategy, which states that treatment in older British women should be equivalent to that in younger patients unless precluded by co-morbidity or patient choice. Oncoplastic and reconstructive techniques are increasingly available to women with breast cancer. A review of the literature was carried out to investigate use of these techniques in older patients., Methods: A MEDLINE search was conducted to identify studies relating to oncoplastic and reconstructive surgery in the elderly., Results and Conclusion: Nine studies were identified and included in the review. Older patients undergoing reconstruction, particularly autologous reconstruction, have outcomes that are at least as good as those achieved in younger patients, yet are far less likely to be offered these techniques. Issues influencing oncoplastic and reconstructive surgery in the elderly include: lack of standard pathways of care, concerns regarding higher operative risk, lack of evidence regarding outcomes, preconceptions regarding body image and lack of engagement with the decision-making process. A minority of older women are likely to accept reconstruction, but those who do are pleased with the results and experience good quality of life. There is now a range of safe oncoplastic and reconstructive options that could be considered as an alternative to standard mastectomy or wide local excision in older patients., (© 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.)

Background: Reduction mammaplasty during lumpectomy allows more generous resection and minimizes potential for poor cosmesis as compared with breast conservation therapy alone., Objectives: The authors assessed the benefits of oncoplastic reduction for margin status in patients with breast cancer by conducting a retrospective review of cases of tumor resection alone vs tumor resection with oncoplastic reduction., Methods: Patients with breast cancer who underwent lumpectomy performed by a single oncologic surgeon between 2009 and 2013 were included. Patients were stratified into 2 groups based on surgical procedure: tumor resection with oncoplastic reduction (group 1) vs tumor resection alone (group 2). Patient demographics including risk factors, diagnosis, cancer stage, and procedure type were recorded. Tumor size, specimen weight, width of narrowest margin, and receptor status were determined. Outcome variables included margin positivity (≤1 mm), need for re-excision, and conversion to completion mastectomy., Results: A total of 222 breasts from 207 patients were included in the study: 83 in group 1 and 139 in group 2. The patients in group 1 had a lower incidence of positive margins and wider free surgical margins, required re-excision less often, and went on to completion mastectomy less often. Patients in group 1 were younger and had cancer that was more advanced. When controlling for these variables on multivariate regression analysis, the oncoplastic technique was independently associated with fewer positive margins and fewer instances of re-excision., Conclusions: The oncoplastic reduction technique achieves wider free margins and less often necessitates re-excision or subsequent mastectomy. The long-term oncologic effect of this approach deserves further study., Level of Evidence: 4., (© 2014 The American Society for Aesthetic Plastic Surgery, Inc.)

Objectives: A prior study at our institution showed a marked reduction in reoperation for margin reexcision following the development of an intraoperative frozen section evaluation of margins (FSM) practice on lumpectomy specimens from patients undergoing breast-conserving therapy (BCT). This study aimed to examine the frequency of FSM utilization, FSM pathology performance, and outcomes for BCT patients undergoing margin reexcision only., Methods: Consecutive reexcision-only specimens were reviewed from a 40-month period following the development of the FSM practice. Clinicopathologic features and patient outcomes were assessed., Results: FSM was performed in 46 (30.7%) of 150 reexcision-only operations. Of the 46 operations with FSM, there were 28 (60.9%) true-negative, 12 (26.1%) true-positive, six (13.0%) false-negative, and no false-positive cases. There was no difference in further reexcision, total operations, or conversion to mastectomy among patients with and without FSM. Need for further reexcision was significantly associated with tumor multifocality (P = .008)., Conclusions: Despite overall good pathology performance for FSM in reexcision-only specimens, use of FSM did not affect patient outcome. Rather, underlying disease biology appeared most significant in predicting whether adequate surgical margins could be attained., (Copyright© by the American Society for Clinical Pathology.)

Background: Neoadjuvant chemotherapy (NACT) is a standard treatment option for primary operable breast cancer when adjuvant chemotherapy is indicated., Methods: This article reviews the use of NACT in breast cancer treatment., Results: Pathological complete response (pCR) rates of up to 60 per cent have been reached for certain breast cancer subgroups. Patients achieving a pCR have a lower locoregional recurrence rate. Nevertheless, the rate of breast-conserving surgery seems to be stable at around 65-70 per cent, although more than 80 per cent of patients respond to NACT. The risk of local relapse does not appear to be higher after NACT, which supports the recommendation to operate within the new margins, as long as there is no tumour in the inked area of the surgical specimen. However, tumours do not shrink concentrically and the re-excision rate is higher after NACT. Mastectomy rates for lobular carcinomas remain high irrespective of tumour response. The role of sentinel lymph node biopsy (SLNB) in the context of NACT has been studied in recent years, and it is not yet completely clear which type of axillary staging is the most suitable. SLNB before NACT in clinically node-negative patients has been the preferred option. However, this practice is currently changing, and it seems advisable to have the SLNB after NACT to reduce the risk of a false-negative SLNB., Conclusion: Overall, patients do benefit from NACT, especially those with human epidermal growth factor receptor 2-positive and triple-negative breast cancer, but surgical/local procedures need to be adapted., (© 2014 BJS Society Ltd.

Since December 2009, after breast-conserving surgery for Stage 0-I cancer of the left breast, 21 women with relatively pendulous breasts underwent computed tomography prone and supine simulations. The adjuvant radiotherapy was 50 Gy in 25 fractions to the left breast alone. Four plans--conventional wedged tangents and forward intensity-modulated radiotherapy (fIMRT) in supine and prone positions--were generated. fIMRT generated better homogeneity in both positions. Prone position centralized the breast tissue by gravity and also shortened the breast width which led to better conformity in both planning techniques. Prone fIMRT significantly reduced doses to left lung, Level I and Level II axilla. The mean cardiac doses did not differ between positions. Among the four plans, prone fIMRT produced the best target dosimetry and normal organ sparing. In subgroup analysis, patients with absolute breast depth > 7 cm in the prone position or breast depth difference > 3 cm between positions had significant cardiac sparing with prone fIMRT. Sixteen patients with significant cardiac sparing in prone position were treated using prone fIMRT and the others using supine fIMRT. All patients received a supine electron tumor bed boost of 10 Gy in 5 fractions. No patients developed Grade 2 or worse acute or late toxicities. There was no difference in the number of segments or beams, monitor units, treatment time, or positioning reproducibility between prone and supine positions. At a median follow-up time of 26.8 months, no locoregional or distant recurrence or death was noted.

Intraoperative frozen section (FS) margin evaluation is not common practice for patients undergoing breast conservation therapy (BCT), but offers a significant reduction in reoperation. In this study, a technique to allow for more effective freezing of breast tissue was developed to perform FS evaluation of lumpectomy margins (FSM) for all patients undergoing BCT at an ambulatory surgery center. FS evaluation of sentinel lymph node biopsy specimens was performed concurrently. One hundred eighty-one study and 188 control patients, with and without FS evaluation, were compared. Reexcision was reduced 34% (from 48.9% to 14.9%) and reoperation was reduced 36% (from 55.3% to 19.3%) with FS evaluation. Most of the decrease in reoperative rate was because of a decrease in the need for margin reexcision. The number of patients requiring 1, 2, or 3 operations to complete therapy was 84, 92, and 12, respectively, in the control group, and 146, 33, and 2, respectively, in the study group. Lobular subtype, multifocal disease, and larger tumor size (≥2 cm) were significantly associated with failure of FSM to prevent reoperation, but reoperation rates were still significantly decreased in this subgroup of patients (from 75.5% to 43.8%) with FSM. This study highlights an innovative yet simple and adaptable FS approach that resulted in a nearly 3-fold reduction in reoperation for patients undergoing BCT.

Breast-conserving therapy (BCT) and mastectomy have equal survival outcomes. Rates of local recurrence after BCT have declined steadily, largely as a result of the widespread use of systemic therapy. Sentinel node biopsy has replaced axillary dissection for staging the axilla, and in women undergoing BCT with whole-breast irradiation (WBI), axillary dissection is not needed for local control or survival in those with fewer than three involved sentinel nodes. Alternatives to 6 weeks of WBI have been shown to be safe and effective for subsets of breast cancer patients, and the use of preoperative chemotherapy allows BCT in some women who require mastectomy if surgery is the initial step in treatment. The combination of the smaller cancers detected with screening and the routine use of multimodality therapy has resulted in a decrease in the morbidity of local therapy and improved cancer treatment outcomes.
