Trends in Immediate Postmastectomy Breast Reconstruction in the United Kingdom

A combination of fat grafting with inferior dermal flap in breast reconstruction following prophylactic mastectomy: A cohort study

BACKGROUND

Breast reconstruction following prophylactic mastectomy in women with ptotic or hypertrophic breasts often poses challenges. We describe a combined technique of large-volume fat grafting (>100 mL) and an inferior dermal flap, aiming to improve aesthetic outcomes and patient satisfaction.

METHODS

We conducted a retrospective analysis of 21 patients undergoing immediate breast reconstruction with the described technique. All patients were asked to complete the BREAST-Q questionnaire preoperatively and at least 12 months postoperatively (median interval: 20 months). Statistical analysis (Wilcoxon signed-rank test) was used to assess changes in satisfaction and well-being; aesthetic outcomes were scored by an independent, multidisciplinary team.

RESULTS

Among 13 patients with complete BREAST-Q data, satisfaction with the breasts increased significantly from a median score of 38-85 (p = 0.002), psychosocial well-being from 57-70 (p = 0.045), and physical well-being (chest) from 68 to 81 (p = 0.045). Sexual well-being rose from 47-63 (p = 0.023). Aesthetic evaluation by an independent panel showed notable improvements in breast symmetry, shape, and overall appearance. Minimal and asymptomatic fat necroses or oil liponecrotic pseudocysts were observed.

CONCLUSIONS

Combining large-volume fat grafting with an inferior dermal flap appears promising for women with ptotic breasts, yielding high satisfaction and low complication rates. Despite requiring multiple operative stages, this autologous reconstruction technique may offer a less invasive alternative for high-risk patients seeking natural outcomes without implants.

Increasing Rates but Persistent Variability of Immediate Breast Reconstruction: Real-Time Data from a Population-Based Study (2012-2022)

INTRODUCTION

Preserving the breast contour after mastectomy is proven to be beneficial for the quality of life of a large group of patients with breast cancer (BC). The aim of the present study is to provide an up-to-date overview of immediate breast reconstruction (IBR) in hospitals in the Netherlands over the past 10 years.

PATIENTS AND METHODS

Nationwide data of patients with BC who underwent a mastectomy for ductal carcinoma in situ (DCIS) or invasive BC between January 2012 and September 2022 were requested from the Dutch Breast Cancer Audit (NBCA). Primary outcome was the incidence and trend in application of IBR. Secondary outcomes were factors associated with the use of IBR and the variation among Dutch hospitals.

RESULTS

In total, 56,164 patients underwent a mastectomy for DCIS (n = 8334) or invasive BC (n = 47,830) (2012-2022). The use of IBR for DCIS increased from 39 in 2012 to 48% in 2022 (2012-2017; range 0-85% and 2018-2021; range 0-83%). For DCIS, age < 50 years and lower DCIS grade were positively associated with IBR. The use of IBR for invasive BC increased from 16 in 2012 to 29% in 2022 (2012-2017; range 0-74%, 2018-2022; range 0-77%). For invasive BC, age < 40 years, neoadjuvant chemotherapy, and no adjuvant radiotherapy were positively associated with IBR.

CONCLUSION

Despite an overall increase of IBR, national variations remain. Further prospective research is initiated ( www.decidestudie.com ) to investigate this variation, which may lead to a more even distribution of IBR use among hospitals in the Netherlands.

Three and twelve-month analysis of the PROM-Q study: comparison of patient-reported outcome measures using the BREAST-Q questionnaire in pre- vs. sub-pectoral implant-based immediate breast reconstruction

PURPOSE

Implant-based breast reconstruction (IBR) is being increasingly performed with implant placed above the pectoral muscle (pre-pectoral), instead of below the pectoral muscle (sub-pectoral). Currently, there is a lack of comparative data on clinical and patient-perceived outcomes between pre- vs. sub-pectoral IBR. We investigated whether this difference in surgical approach influenced clinical or patient-perceived outcomes.

METHODS

This prospective non-randomised longitudinal cohort study (ClinicalTrials.gov identifier: NCT04842240) recruited patients undergoing immediate IBR at the Leeds Breast Unit (Sep 2019-Sep 2021). Data collection included patient characteristics and post-operative complications. Patient-Reported Outcome Measures were collected using the BREAST-Q questionnaire at baseline, 2 weeks, 3- and 12-months post-surgery.

RESULTS

Seventy-eight patients underwent IBR (46 patients pre-pectoral; 59% vs. 32 patients sub-pectoral; 41%). Similar complication rates were observed (15.2% pre-pectoral vs. 9.4% sub-pectoral; p = 0.44). Overall implant loss rate was 3.8% (6.5% pre-pectoral vs. 0% sub-pectoral; p = 0.13). Respective median Breast-Q scores for pre- and sub-pectoral IBR at 3 months were: breast satisfaction (58 vs. 48; p = 0.01), psychosocial well-being (60 vs. 57; p = 0.9), physical well-being (68 vs. 76; p = 0.53), and Animation Q scores (73 vs. 76; p = 0.45). Respective Breast-Q scores at 12 months were: breast satisfaction (58 vs. 53; p = 0.3), psychosocial well-being (59 vs. 60; p = 0.9), physical well-being (68 vs. 78; p = 0.18), and Animation Q scores (69 vs. 73; p = 0.4).

CONCLUSIONS

This study demonstrates equivalent clinical and patient-perceived outcomes between pre- and sub-pectoral IBR. The study findings can be utilised to aid informed decision making regarding either surgical option.

Latissimus dorsi flap for breast reconstruction: a large single-institution evaluation of surgical outcome and complications

PURPOSE

The use of autologous tissues is considered gold standard for patients undergoing breast reconstruction and is the preferred method in the post-radiation setting. Although the latissimus dorsi flap (LDF) has been replaced by abdominal flaps as technique of choice, it remains a valuable option in several specific clinical situations and its use has been regaining popularity in recent years. In this work, we present an 18-year retrospective analysis of a single-institution single-surgeon experience with LDF-based reconstruction with focus on early complications and reconstructive failures.

METHODS

Hospital records of all patients undergoing breast surgery for any reason in the Certified Breast Cancer Center, Regio Klinikum Pinneberg, Germany between April, 1st 2005 and October, 31st 2022 were reviewed. 142 consecutive LDF-based reconstructive procedures were identified. Detailed information was gathered on patient characteristics, treatment-related factors, and complications.

RESULTS

One hundred forty patients (139 female, 1 male) received 142 LDF-based surgeries. The flap was used mainly for immediate breast reconstruction with or without implant (83% of patients), followed by defect coverage after removal of a large tumor (7%), implant-to-flap conversion with or without placement of a new implant (6%), and delayed post-mastectomy reconstruction (4%). The use of LDF decreased between 2005 and 2020 (2005: 17, 2006: 13, 2007: 14, 2008: 16, 2009: 5, 2010: 9, 2011: 8, 2012: 3, 2013: 10, 2014: 8, 2015: 8, 2016: 7, 2017: 7, 2018: 4, 2019: 4, 2020: 2, 2021: 6, 2022: 4). Surgery was performed for invasive breast cancer in 78%, ductal carcinoma in situ in 20% and other reasons such as genetic mutation in 1% of patients. Ipsilateral radiation therapy was received by 12% of patients prior to LDF surgery and by 37% after the surgery. 25% of patients were smokers. The median duration of surgery, including all procedures conducted simultaneously such as e.g., mastectomy, axillary surgery, or implant placement, was 117 min (range 56-205). Patients stayed in the hospital for a median of 7 days (range 2-23 days). The most common complication was seroma (26%), followed by wound dehiscence (8%), surgical site infection (7%), partial skin and/or nipple necrosis of any size (7%) and hematoma requiring surgical evacuation (2%). 19% of all patients required seroma aspiration or drainage, mostly at the donor site and performed under ultrasound guidance in the ambulatory setting. Flap loss due to necrosis occurred in 2% of patients.

CONCLUSIONS

Latissimus dorsi flap is a well-established surgical technique commonly used for immediate breast reconstruction as well as defect coverage in locally advanced breast cancer. To the best of our knowledge, this is one of the largest single-surgeon analyses of early complications in patients receiving LDF. As expected, seroma was the most common complication observed in nearly one third of patients and requiring a therapeutic intervention in every fifth patient. Serious adverse events occurred rarely, and flap loss rate was very low.

Rising age-specific rates of immediate breast reconstruction after mastectomy: Report from an Italian Breast Unit

BACKGROUND AND OBJECTIVES

Immediate breast reconstruction (IBR) represents a fundamental part in the management of patients receiving mastectomy. In recent years, there has been an increasing trend in the use of IBR in all age groups. The study aims were to evaluate the age-specific trend of IBR, and to discuss its effects in work organization at an Italian Breast Unit.

METHODS

We searched for women diagnosed with breast cancer between 2010 and 2019, focusing on IBR rates in patients who received mastectomy. Age-specific trends were assessed using the Cochrane-Armitage test. Differences in operative times and hospital stay between women undergoing mastectomy + IBR (Ma + IBR) or mastectomy alone (Ma) were evaluated by Student's t test or χ2 test.

RESULTS

Among 1915 patients, 62.4% underwent breast conserving surgery (BCS), and 37.6% mastectomy. Overall, rates of Ma + IBR increased from 32% in 2010 to 58% in 2019 (p < 0.001). Although rates of IBR rose in all age groups, the trend was significantly increased among patients aged 50-59 (p < 0.001), 60-69 (p < 0.0001), and 70-79 (p < 0.05).

CONCLUSIONS

Rates of Ma + IBR have increased over years, especially among older women. Ma + IBR resulted in longer operative times and hospital stay than Ma alone. These findings imply that, in the near future, resources should be implemented to improve and strengthen the surgical activity of Breast Units, to support the increasing use of IBR in women of all age groups.

Return to Activities of Daily Living after Breast Cancer Surgery: An Observational Prospective Questionnaire-Based Study of Patients Undergoing Mastectomy with or without Immediate Reconstruction

Background

Patients often ask about the time taken to return to activities of daily living (ADLs) after breast surgery, but there is a lack of data to give accurate guidance. We aimed to assess the feasibility of a study to determine the time taken to return to ADLs after mastectomy with or without breast reconstruction.

Materials and Methods

A prospective multicentre, self-reported questionnaire-based feasibility study of women who had undergone mastectomy ± reconstruction was performed, between Jan 2017 and Dec 2019. Women were asked to self-report when they returned to 15 ADLs with a 5-option time scale for "return to activity."

Results

The questionnaire was returned by 42 patients (median [range] age: 64 [31-84]). Of these, 22 had simple mastectomy, seven mastectomy and implant reconstruction, seven mastectomy and autologous reconstruction (DIEP), and six did not specify. Overall, over 90% could manage stairs and brush hair by two weeks and 84% could get in and out of the bath by four weeks. By 1-2 months, 92% could do their own shopping and 86% could drive. 68% of women employed returned to work within four months. Compared to simple mastectomy, patients undergoing reconstruction took a longer time to return to getting in/out of bath (<2 vs. 2-4 weeks), vacuuming (2-4 weeks vs. 1-2 months), and fitness (1-2 vs. 3-4 months). There was a slower return to shopping (1-2 months vs. 2-4 weeks), driving and work (both 3-4 vs. 1-2 months), and sports (3-4 vs. 1-2 months) in autologous reconstruction compared to implant reconstruction.

Conclusion

This study is feasible. It highlights slower return to specific activities (particularly strength-based) in reconstruction patients, slower in autologous compared with implant reconstruction. The impact on return to ADLs should be discussed as part of the preoperative counselling as it will inform patients and help guide their decision making. A larger study is required to confirm these results.

Oncoplastic and reconstructive breast surgery

This article provides an overview of the principles and techniques of oncoplastic and reconstructive breast surgery for patients with early-stage breast cancer. Oncoplastic breast surgery (OPBS) with partial breast reconstruction is a natural evolution in the application of breast conserving surgery and permits wide surgical resection of tumours that might otherwise mandate mastectomy and whole breast reconstruction. These reconstructive techniques must be optimally selected and integrated with ablative breast surgery together with non-surgical treatments such as radiotherapy and chemotherapy that may be variably sequenced with each other. A multidisciplinary approach with shared decision-making is essential to ensure optimal clinical and patient-reported outcomes that address oncological, aesthetic, functional and psychosocial domains. Future practice of OPBS must incorporate routine audit and comprehensive evaluation of outcomes.

Implant-Based Breast Reconstruction after Risk-Reducing Mastectomy in BRCA Mutation Carriers: A Single-Center Retrospective Study

Women with BRCA gene mutations have a higher lifetime risk of developing breast cancer. Furthermore, cancer is usually diagnosed at a younger age compared to the wild-type counterpart. Strategies for risk management include intensive surveillance or risk-reducing mastectomy. The latter provides a significant reduction of the risk of developing breast cancer, simultaneously ensuring a natural breast appearance due to the preservation of the skin envelope and the nipple-areola complex. Implant-based breast reconstruction is the most common technique after risk-reducing surgery and can be achieved with either a submuscular or a prepectoral approach, in one or multiple stages. This study analyzes the outcomes of the different reconstructive techniques through a retrospective review on 46 breasts of a consecutive, single-center case series. Data analysis was carried out with EpiInfo version 7.2. Results of this study show no significant differences in postoperative complications between two-stage tissue expander/implant reconstruction and direct-to-implant (DTI) reconstruction, with DTI having superior aesthetic outcomes, especially in the prepectoral subgroup. In our experience, the DTI prepectoral approach has proven to be a safe and less time-consuming alternative to the submuscular two-stage technique, providing a pleasant reconstructed breast and overcoming the drawbacks of subpectoral implant placement.

The Duration of Postoperative Antibiotics in Autologous Breast Reconstruction: A Systematic Review and Meta-Analysis

Although prophylactic antibiotic use following autologous breast reconstruction post-mastectomy is a common practice, there is no consensus in the literature regarding its duration. Antibiotic stewardship is important to minimise multi-resistant organisms as well as mitigate the associated side effects. Currently, there are no published guidelines regarding the duration of prophylactic antibiotics in autologous breast reconstruction surgery following mastectomy. The authors searched the online literature regarding the administration of antibiotics for autologous breast reconstruction surgery post-mastectomy. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed. The primary outcome measure was the incidence of surgical site infections (SSIs). Three studies met the inclusion criteria and included a total of 1,400 patients. Overall, 101 (7.2%) SSIs were observed. There was no significant difference in the rate of SSIs when comparing the use of antibiotics for less than or longer than 24 hours postoperatively (odds ratio = 1.434, p = 0.124). There is no significant difference between SSIs with the use of antibiotics for longer than 24 hours when compared to less than 24 hours. Further studies in the form of randomised controlled trials are required to assess the effects of prophylactic antibiotic duration in autologous breast reconstruction following mastectomy.

Pre-operative Radiotherapy And Deep Inferior Epigastric Artery Perforator (DIEP) flAp study (PRADA): Aesthetic outcome and patient satisfaction at one year

INTRODUCTION

The optimal combination of radiotherapy and breast reconstruction has not yet been defined. Post-mastectomy radiotherapy (PMRT) has deleterious effects on breast reconstruction, leading to caution amongst surgeons. Pre-operative radiotherapy (PRT) is a growing area of interest, is demonstrated to be safe, and spares autologous flaps from radiotherapy. This study evaluates the aesthetic outcome of PRT and deep inferior epigastric artery perforator (DIEP) flap reconstruction within the Pre-operative Radiotherapy And Deep Inferior Epigastric artery Perforator (DIEP) flAp (PRADA) cohort.

METHODS

PRADA was an observational cohort study designed to evaluate the feasibility and safety of PRT for women undergoing neoadjuvant chemotherapy and DIEP reconstruction. Panel evaluation of 3D surface images (3D-SIs) and patient-reported outcome measures (BREAST-Q) for a subset of women in the study were compared with those of a DIEP-PMRT cohort who had undergone DIEP reconstruction and PMRT.

RESULTS

Seventeen out of 33 women from the PRADA study participated in this planned substudy. Twenty-eight women formed the DIEP-PMRT cohort (median follow-up 23 months). The median (inter-quartile range [IQR]) 'satisfaction with breasts' score at 12 months for the PRADA cohort was significantly better than the DIEP-PMRT cohort (77 [72-87] versus 64 [54-71], respectively), p=0.01). Median [IQR] panel evaluation (5-point scale) was also significantly better for the PRADA cohort than for the DIEP-PMRT cohort (4.3 [3.9-4.6] versus 3.6 [2.8-4] p=0.003).

CONCLUSIONS

Aesthetic outcome for the PRADA cohort was reported to be 'good' or 'excellent' in 93% of cases using a bespoke panel assessment with robust methodology. Patient satisfaction at one year is encouraging and superior to DIEP-PMRT at 23 months. Switching surgery-radiotherapy sequencing leads to similar breast aesthetic outcomes and warrants further large-scale, multi-centre evaluation in a randomised trial.

Direct-to-Implant Subcutaneous Breast Reconstruction: A Systematic Review of Complications and Patient's Quality of Life

BACKGROUND

The use of direct-to-implant subcutaneous breast reconstruction has increased over the last years. The goal of this systematic review is to deliver an updated review of the safety of this technique and its impact on quality of life. We also compare subcutaneous vs submuscular complications, through meta-analysis.

METHODS

Literature review through PubMed and Cochrane Library databases were performed by PRISMA criteria. Thirty-nine studies met inclusion criteria for subcutaneous review and 15 studies met inclusion criteria for meta-analysis. All included studies were evaluated for complications and answers to the BREAST-Q. Data were analysed using Microsoft Excel, IBM SPSS, and Cochrane RevMan.

RESULTS

In 2863 patients and 3988 breasts that undergone direct to implant subcutaneous breast reconstruction, 8,21% had rippling, 5,64% seroma, 1,74% hematoma, 3,40% infection, 3,01% wound dehiscence, 3,93% skin necrosis, 3,34% nipple-areolar-complex (NAC) necrosis, 3,07% capsular contracture, 0,00% animation deformity, and 3,83% an implant removal. Meta-analysis showed a statistically significant decrease in the odds ratio of animation deformity, a but statistically significant higher odds ratio of rippling. Subcutaneous and submuscular reconstructions had similar BREAST-Q scores.

CONCLUSIONS

Direct-to-implant subcutaneous breast reconstruction does not harm the patient's quality of life, comparatively with submuscular, saving the pectoral muscle from dissection and preventing animation deformity, but increasing the risk of rippling.

A Comparative Study of Secondary Procedures after Subpectoral and Prepectoral Single-Stage Implant-Based Breast Reconstruction

BACKGROUND

Implant-based breast reconstruction (IBR) is the most commonly used procedure to reconstruct the breast after mastectomy. The advantages and disadvantages of subpectoral versus prepectoral implant placement remain a matter of debate. This study compares the need for secondary aesthetic procedures between prepectoral and subpectoral IBR.

METHODS

This is a retrospective cohort study of consecutive patients who underwent subpectoral or prepectoral IBR between 2015 and 2018 under a single surgeon at a tertiary breast unit. The primary endpoint was the number of secondary procedures performed to improve the aesthetic outcome. Secondary endpoints included the number of secondary procedures during the first year.

RESULTS

A total of 271 one-stage IBRs were performed (subpectoral, n = 128 in 74 patients; prepectoral, n = 143 in 84 patients). Overall, more patients required secondary procedures in the subpectoral group (36.5% versus 19%; P = 0.014), although through longer follow-up. The most common procedures were pocket revision and implant exchange [11.7% versus 3.5% ( P = 0.010); 11.7% versus 4.2% ( P = 0.021)], whereas fat grafting was similar between the two groups (46% versus 40.5%; P = 0.777). When adjusted for follow-up time, there was no significant difference in the number of secondary procedures undertaken in the subpectoral versus the prepectoral group (21% versus 16%, respectively; P = 0.288) at 1 year.

CONCLUSIONS

The requirement for secondary procedures at 1 year was not different between groups. The need for fat grafting was not increased following prepectoral IBR.

Comparison of Outcomes Following Prepectoral and Subpectoral Implants for Breast Reconstruction: Systematic Review and Meta-Analysis

(1) Background: Implant-based breast reconstruction following mastectomy helps to restore quality of life while aiming at providing optimal cosmetic outcomes. Both prepectoral (PP) and subpectoral (SP) breast implants are widely used to fulfill these objectives. It is, however, unclear which approach offers stronger postoperative benefits. (2) Methods: We performed a systematic review of the literature through PubMed, Cochrane Library, and ResearchGate, following the PRISMA guidelines. Quantitative analysis for postoperative pain as the primary outcome was conducted. Secondary outcomes included patient satisfaction and postoperative complications such as seroma, implant loss, skin necrosis, wound infection, and hematoma. (3) Results: Nine articles involving 1119 patients were retrieved. Our results suggested increased postoperative pain after SP implants and significantly higher rates of seroma following PP implants (p < 0.05). Patient satisfaction was found to be similar between the two groups; however, the heterogeneity of measurement tools did not allow us to pool these results. The rates of implant loss, skin necrosis, wound infection, and hematoma showed no significant differences between the two cohorts. (4) Conclusion: Our data suggest that both implant placements are safe and effective methods for breast reconstruction following mastectomy. However, homogeneity in outcome measurements would allow one to provide stronger statistical results.

Physical Characteristics of SurgiMend Meshed Biological ADM in Immediate Prepectoral Implant Breast Reconstruction

With increasing acceptance of prepectoral implant breast reconstruction, there has been a requirement for biological acellular dermal matrices with conformational properties, high tensile strength, and rapid integration. SurgiMendPRS Meshed is a biological acellular dermal matrix derived from fetal calf with these specific characteristics for prepectoral implant breast reconstruction. The aim of this study was to test the performance of this mesh by recreating its surgical use ex-vivo using a variety of implants in an effort to define its physical properties. The mesh is usually attached with a number of interrupted sutures to the implant periphery, the variable being at the inferior border, where it can be attached as a snug fit at the level of the inframammary crease (“tent” technique) or sewn behind the implant, cradling the lower pole (“hammock” technique). The results show mesh elasticity to stretch with increasing implant weight. When used as a “hammock,” greater stretch was demonstrated compared with the “tent” technique, allowing greater degrees of ptosis to be achieved. The suture points demonstrated lines of tension that progress evenly over the anterior implant surface. The mesh performed better when used at maximum stretch, but should not be forcibly stretched over an implant as the lines of stress show uneven distribution of lines of tension. These data provide a structural basis on optimum clinical use of this acellular dermal matrix in prepectoral implant breast reconstruction.

Prepectoral immediate breast reconstruction with polyurethane foam-coated implants: Feasibility and early results in risk-reducing and therapeutic mastectomies

BACKGROUND

There is a renewed interest for prepectoral reconstruction. We aimed to describe the feasibility and the early complications associated with immediate one-stage direct-to-implant (DTI) reconstruction using prepectoral anatomical polyurethane (PU) foam-coated implants alone, for women with breast cancer or mutation carriers undergoing risk-reducing surgery.

METHODS

We performed a single-center, retrospective review of 50 patients (mean age of 49 years), who underwent skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM) and immediate prepectoral PU implant-based reconstruction. All procedures were performed by the same senior operator, from July 2018 to March 2020.

RESULTS

A total of 64 mastectomies (25 SSMs and 39 NSMs) with one-stage prepectoral PU foam-coated implant reconstruction were performed. Out of 50 patients, 6 required surgical revision within 30 days, because of hematoma (2), wound dehiscence (2) infection (1), and full thickness nipple-areolar complex (NAC) necrosis (1). Four patients developed a cutaneous rash with spontaneous resolution. Statistical analysis showed a significant influence of hypothyroidism and previous radiotherapy on the risk of complications. The association with prior radiotherapy (pRT) was not significant using binary logistic regression. When excluding oncological reasons and patient's wish for NAC excision, our decision to perform an NSM was influenced by breast cup size, preoperative measurements, and breast weight.

CONCLUSIONS

Early experience with immediate prepectoral DTI reconstruction with PU-covered implants alone suggests that it is a reliable procedure. Prior breast irradiation does not increase postoperative complication rates in our series. NAC preservation was decided according to preoperative lower breast measurements.

Pre-pectoral one-stage breast reconstruction with anterior biological acellular dermal matrix coverage

Background

Pre-pectoral implant breast reconstruction (IBR) is gaining popularity. Several techniques using different types of meshes and methods of placement have been described, but no method is currently considered standard. The aim of this study was to evaluate the outcomes of pre-pectoral IBR using acellular dermal matrix (ADM) for anterior implant cover.

Methods

Retrospective cohort study of consecutive patients who underwent pre-pectoral IBR between November 2016 to August 2018. Data on demographics, adjuvant therapies and operative technique was collected. Postoperative complications, length of hospital stay and secondary cosmetic procedures were recorded. Statistical analysis was performed using descriptive statistics, non-parametric tests and logistic regression.

Results

One hundred and eleven pre-pectoral IBR were performed in 65 patients. Median age was 41 [interquartile range (IQR), 35-51.5] years, and BMI 22 (IQR, 20.4-24.4) kg/m². Therapeutic mastectomy was performed in 33 procedures with nipples preservation in 78 cases. The median mastectomy weight and implant volume was 360 (IQR, 220-533) gr, and 445 (IQR, 400-475) cc respectively. At a median follow-up of 18 (IQR, 12-22.5) months, 37 mastectomies had at least 1 complication, but only 12 required surgery. The implant loss rate was 4.5% (5 cases). Lipofilling as secondary procedure was performed in 10.8% of cases. Factors associated with post-operative complications on univariate analysis were nipple preservation (P=0.028), BMI (P=0.01) and implant volume (P=0.027) but these did not remain significant on multivariate analysis.

Conclusions

Pre-pectoral IBR using ADM for anterior implant cover is associated with low complication and reconstructive failure rate. Patient selection and meticulous surgical technique are important for successful outcome.

Adipose tissue-derived mesenchymal stem cells for breast tissue regeneration

With an escalating incidence of breast cancer cases all over the world and the deleterious psychological impact that mastectomy has on patients along with several limitations of the currently applied modalities, it's plausible to seek unconventional approaches to encounter such a burgeoning issue. Breast tissue engineering may allow that chance via providing more personalized solutions which are able to regenerate, mimicking natural tissues also facing the witnessed limitations. This review is dedicated to explore the utilization of adipose tissue-derived mesenchymal stem cells for breast tissue regeneration among postmastectomy cases focusing on biomaterials and cellular aspects in terms of harvesting, isolation, differentiation and new tissue formation as well as scaffolds types, properties, material-host interaction and an in vitro breast tissue modeling.

Long-term outcomes of latissimus dorsi flap breast reconstructions: A single-centre observational cohort study with up to 12 years of follow up

INTRODUCTION

The Latissimus Dorsi Myocutaneous Flap (LDMF) is used in post-mastectomy reconstruction. This study has evaluated long-term (up to 12 years) surgical- and patient-reported outcomes from LDMF procedures.

METHOD

A retrospective analysis of consecutive LDMF procedures in two UK hospitals, performed between 2006 and 2016. Case notes were reviewed for indications and outcomes. Patients were sent the BREAST-Q^Ⓡ survey by post. Outcomes, including surgical adverse events, revision, and implant loss rates, were correlated with patient risk factors.

RESULTS

A BREAST-Q was posted to 199/248 LDMF patients in 2018, (excluding 49 patients due to death, reduced cognitive function and incorrect coding) of whom 77 patients responded (38.7%). In 188 cases (representing 208 LDMFs), surgical outcomes were assessable. Median time since LDMF surgery was 7 years (range 2-12). Rates of acute implant loss were 9/139 (6.4%), flap necrosis 7/208 (3.4%), shoulder stiffness 4/208 (1.9%), chronic pain 24/208 (11.5%) and unplanned revision surgery 13/208 (7%). Median satisfaction levels were high with 78% of patients satisfied with treatment outcomes, 65% of patients satisfied with their breasts, 71% of patients satisfied psychosocially and 75% of patients satisfied with their chest. Receipt of radiotherapy was not associated with a higher risk of flap necrosis or capsule formation.

CONCLUSION

Long-term follow-up of a large cohort of LDMF reconstruction patients show relatively low levels of adverse events and unplanned revision surgery and high patient satisfaction, which demonstrates how temporally robust the technique is. With the rise in popularity of acellular dermal matrix reconstructions, the LDMF has relatively fallen out of favour but its potential in primary and delayed reconstruction is demonstrated.

Patient-Reported Outcomes of Three Different Types of Breast Reconstruction with Correlation to the Clinical Data 5 Years Postoperatively

BACKGROUND

The aim of this study was to compare long-term clinical and patient-reported outcomes in terms of satisfaction and health-related quality of life (HRQoL) following postmastectomy breast reconstruction using BREAST-Q in patients undergoing implant-based reconstruction, abdominal-based autologous reconstruction, and combined reconstruction (with implant and LD flap or implant and TDAP flap).

METHODS

A cross-sectional study was conducted. Patients had undergone delayed postmastectomy breast reconstruction and completed the BREAST-Q reconstruction module. The results were related to the clinical data obtained from the clinic's patient record system. A 5-year examination was included. Mean scores and standard deviations were calculated. Kruskal-Wallis test, Chi-square goodness of fit test and Chi-square test were used for the statistical analysis.

RESULTS

Overall, 110 patients (n = 24 implant, n  = 38 autologous, n = 48 combination) were included. Patients with autologous reconstruction reported greater postoperative satisfaction with breasts (p < 0.001), satisfaction with outcome (p < 0.001), psychosocial well-being (p = 0.001), and sexual well-being (p = 0.051).

CONCLUSION

This study represents a comprehensive long-term examination of postmastectomy breast reconstruction. Autologous reconstruction patients had higher postoperative satisfaction and HRQoL than patients receiving other types of reconstruction despite having more intense oncological therapy and the highest mean number of follow-up surgical procedures.

Complication Rate of Prepectoral Implant-based Breast Reconstruction Using Human Acellular Dermal Matrices

Implant-based breast reconstruction (IBR) is currently the most frequently performed reconstructive technique post mastectomy. Even though submuscular IBR continues to be the most commonly used technique, mastectomy technique optimization, the possibility to check skin viability with indocyanine green angiography, the enhanced propensity of patients undergoing prophylactic mastectomies, and the introduction of acellular dermal matrices (ADMs) have paved the way to the rediscovery of the subcutaneous reconstruction technique. The aim of this article is to update the complication rate of immediate and delayed prepectoral IBR using human ADMs (hADMs).

METHODS

A literature search, using PubMed, Medline, Cochrane, and Google Scholar database according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, was conducted to evaluate complication rates of prepectoral implant-based reconstructions using hADMs. The following MeSH terms were used: "prepectoral breast reconstruction acellular dermal matrix," "prepectoral breast reconstruction ADM," "human ADM breast reconstruction," and "human acellular dermal matrix breast reconstruction" (period: 2005-2020; the last search took place on April 2, 2020).

RESULTS

This meta-analysis includes 1425 patients (2270 breasts) who had undergone immediate or delayed prepectoral IBR using different types of hADMs. The overall complication rate amounted to 19%. The most frequent complication was represented by infection (7.9%), followed by seroma (4.8%), mastectomy flap necrosis (3.4%), and implant loss (2.8%).

CONCLUSIONS

The overall complication rate was 19%. The most frequent complications were infection, seroma, and mastectomy flap necrosis, while capsular contracture was rare.

Prepectoral implant pocket conversion in breast reconstruction

Introduction

While many authors have reported their experience in immediate prepectoral breast reconstruction (BR), implant pocket conversion from a submuscular to a prepectoral plane is less well described. The aim of this study is to provide a comprehensive review on plane conversion in implant-based BR, including the indications, surgical techniques, functional, and esthetic results.

Materials and Methods

A literature search via PubMed, Medline, Google Scholar, and Cochrane databases was performed using the following MeSH terms: “prepectoral pocket conversion”, “subcutaneous pocket conversion”, “prepectoral plane conversion”, “subcutaneous plane conversion”, and “prepectoral breast reconstruction”.

Results

Ten articles in which 504 breasts were studied were deemed eligible for inclusion. The indications to perform plane conversion were animation deformity (AD), chronic pain, and implant malposition. Seven studies described complete or partial capsulectomy. The use of acellular dermal matrices (ADM) was reported in all cases except for three studies. The mean follow-up was 10.64 months. There was resolution of AD in 100% of cases. Three studies reported complete resolution of chronic pain. The overall complication rate was 12.102% and capsular contracture (CC) was the most frequent complication. Cosmetic revisions were reported in six studies (9.52%). The use of ADMs and fat grafting appeared to decrease the rate of subsequent CC formation and cosmetic revisions.

Conclusions

The current article represents the first review about implant pocket conversion from a submuscular to a prepectoral plane, delineating its indications, surgical technique, postoperative complications, and functional and esthetic outcomes.

Negative Pressure Wound Therapy Reduces Wound Breakdown and Implant Loss in Prepectoral Breast Reconstruction

Background:

Single-use negative pressure wound therapy (NPWT) has been shown to encourage wound healing. It is often used when patient factors impair wound healing, or in more complex wounds, such as in implant-based breast reconstruction. We report the findings of a prospective cohort study comparing the use of NPWT with standard dressings in prepectoral breast reconstruction.

Methods:

A prospective database of implant-based reconstruction from a single institution was mined to identify patients who underwent prepectoral reconstruction. Patient demographics, operative data, surgical complications, and 90-day outcomes were compared between patients who had NPWT and those who had standard dressings.

Results:

Prepectoral implant-based breast reconstruction was performed on 307 breasts. NPWT dressings were used in 126 cases, with standard dressings used in 181 cases. Wound breakdown occurred in 10 cases after standard dressings versus 1 where NPWT was utilized. Of the standard dressing cases, only 3 implants were salvaged, while 7 cases led to implant loss. The 1 case of wound breakdown in the NPWT cohort settled with conservative measures. The cost of a reconstructive failure was £14,902, and the use of NPWT resulted in a cost savings of £426 per patient.

Conclusions:

The utilization of single-use NPWT reduces the rate of wound breakdown and implant loss in prepectoral implant-based reconstruction. In addition to the significant clinical benefits, this approach is cost-saving compared with standard dressings. These data suggest that prepectoral implant reconstruction should be considered as an indication for the use of NPWT.

Acellular dermal matrices as an adjunct to implant breast reconstruction: Analysis of outcomes and complications

PURPOSE

Acellular dermal matrices (ADM) are increasingly used in implant-based breast reconstruction (IBR). Uncertainty remains with regard to their efficacy and complications. The aim of this study was to evaluate the outcomes and complication rates associated with the use of ADMs in IBR.

METHODS

Retrospective cohort study of patients undergoing ADM-assisted IBR between 2008 and 2013. Cases were identified from a prospectively collected database. Simple descriptive statistics and logistic regression analysis were performed.

RESULTS

A total of 110 patients (175 mastectomies) were included in the analysis. The median age was 46 (19-75) years and the median BMI was 22.2 (16.2-41.5). Seventy nine mastectomies were performed for therapeutic purposes. The median mastectomy weight was 244 (185-335) gr. The majority of reconstructions were performed with fixed volume (n = 115, 66%) or permanent expandable implants (n = 53, 30%) as one-stage procedures. Forty mastectomies were associated with at least one complication. The infection rate was 2.3% (n = 4). Post-operative haematoma developed in 5 cases (2.9%), but only 2 required surgical interventions. Three mastectomies were complicated by nipple necrosis (3.6%), 3 with skin necrosis (1.7%) and 9 with wound dehiscence (5.1%). The capsule formation rate was 2.3% (n = 4). Reconstruction failure with implant loss occurred in 3 cases (1.7%).

CONCLUSIONS

The complication rates following ADM-assisted IBR can be very low with appropriate patient selection and meticulous surgical technique. This supports the safety of using ADM in carefully selected patients. Further research is warranted to assess the health economics of ADM use in IBR.

The future application of nanomedicine and biomimicry in plastic and reconstructive surgery

Plastic surgery encompasses a broad spectrum of reconstructive challenges and prides itself upon developing and adopting new innovations. Practice has transitioned from microsurgery to supermicrosurgery with a possible future role in even smaller surgical frontiers. Exploiting materials on a nanoscale has enabled better visualization and enhancement of biological processes toward better wound healing, tumor identification and viability of tissues, all cornerstones of plastic surgery practice. Recent advances in nanomedicine and biomimicry herald further reconstructive progress facilitating soft and hard tissue, nerve and vascular engineering. These lay the foundation for improved biocompatibility and tissue integration by the optimization of engineered implants or tissues. This review will broadly examine each of these technologies, highlighting areas of progress that reconstructive surgeons may not be familiar with, which could see adoption into our armamentarium in the not-so-distant future.

Association of sociodemographic and oncological features with decision on implant-based versus autologous immediate postmastectomy breast reconstruction in Chinese patients

Background and objectives

Immediate postmastectomy breast reconstruction (IPBR) has gained wide popularity in China. We sought to clarify the prevalence and predictors of implant‐based vs autologous IPBR among Chinese patients.

Methods

A retrospective cohort study was performed using a prospectively maintained database. Women who underwent IPBR during 2001‐2017 were included. The modality‐specific trends were deciphered by curve fitting analysis. The association of sociodemographic and oncological features with the decision for implant‐based vs autologous IPBR was investigated using multivariate logistic regression and structural equation modeling.

Results

Among 905 patients included in the study, 479 underwent implant‐based IPBR and 426 underwent autologous procedures. The implant/autologous ratio has increased exponentially over time. Multivariate analysis demonstrated that unmarried patients with BMI ≤ 24 kg/m², earlier clinical tumor stage, and preoperative pathological diagnosis of noninvasive lesion are more likely to choose implant‐based IPBR compared to autologous procedures. The indirect effects of age, mastectomy type, and neoadjuvant chemotherapy were further demonstrated by the structural equations.

Conclusions

The sociodemographic and oncological features are directly or indirectly associated with the decision on type of IPBR. The findings may facilitate both patients and physicians to make a high‐quality decision by holistic evaluation of the sociodemographic and oncological features.

Immediate and Long-term Complications of Direct-to-implant Breast Reconstruction after Nipple- or Skin-sparing Mastectomy

Background:

Traditionally, breast reconstruction options after mastectomy comprise an autologous flap or staged expander/implant reconstruction, or a combination of both. Recent introduction of skin or nipple-sparing mastectomies have led to much interest in direct-to-implant immediate breast reconstructions. We performed a retrospective review of our initial experience.

Methods:

Between June 1998 and December 2010, 31 of 671 patients (4.6%) who received implant-only breast reconstruction underwent direct-to-implant immediate breast reconstruction after mastectomy for primary or recurrent cancers, or risk reduction. Their files were audited, and the primary factor examined was the failure of reconstruction with loss of prosthesis. Other complications, revision surgery, and aesthetic result are also recorded.

Results:

The mean follow-up period for the 31 patients was 49.5 months. A total of 45 mastectomies were performed for 21 primary and 4 recurrent breast cancers after previous conservation surgery and radiotherapy (RT), and 20 for risk reduction. Ten patients received RT (4 before mastectomy and 6 afterward). Average size of implants was 380.0 g (range, 205–620 g). The most common postoperative complications were seromas (20%); only 1 implant was lost (2.22%). Nineteen breasts required revision surgery after 6 months with 1 more implant lost. Despite the high revision rate, 28 (90.3%) had excellent or good aesthetic result.

Conclusions:

Immediate single-stage direct-to-implant breast reconstruction has a high rate of both immediate postoperative complications and revisions after 6 months, especially after RT. However, most complications are manageable and do not necessarily result in implant loss. Most cases can have a successful outcome without implant loss with excellent or good cosmetic results.

A Prospective Comparison of Short-Term Outcomes of Subpectoral and Prepectoral Strattice-Based Immediate Breast Reconstruction

BACKGROUND

Prepectoral acellular dermal matrix-assisted immediate implant-based breast reconstruction is gaining popularity, involving complete implant coverage with acellular dermal matrix. The authors aimed to compare pain, patient-reported outcome measures (including implant rippling), and safety of prepectoral and subpectoral Strattice-assisted implant-based breast reconstruction.

METHODS

Consecutive patients were recruited prospectively, having either therapeutic or risk-reducing mastectomy. Patients scored their pain three times per day for the first 7 postoperative days on a Likert scale, and completed the BREAST-Q reconstruction module 3 months postoperatively. Clinical records and the authors' prospective complications database were used to compare the early morbidity of the two procedures.

RESULTS

Forty patients were recruited into the study. There was no significant difference in pain scores between the prepectoral group (mean, 1.5) and the subpectoral cohort (mean, 1.5; p = 0.45) during the first 7 days. Thirty-one BREAST-Q questionnaires were returned; mean Q scores were similar for both prepectoral and subpectoral (72 and 71, respectively; p = 0.81) groups. Patients reported significantly more visible implant rippling in the prepectoral group than in the subpectoral group (seven of 13 versus two of 17; p = 0.02). There was no significant difference in length of stay or early morbidity, with implant loss being 4.7 percent in the prepectoral group compared with 0 percent in the subpectoral group.

CONCLUSIONS

Early postoperative pain and quality of life at 3 months are equivalent between groups. Early experience of prepectoral implant placement with complete acellular dermal matrix coverage suggests this is safe and provides good quality of life for patients. Further studies are required to compare short- and long-term outcomes with the current standard forms of reconstruction.

A novel technique for large and ptotic breast reconstruction using a latissimus dorsi myocutaneous flap set at the posterior aspect, combined with a silicone implant, following tissue expander surgery

Large and ptotic breast reconstruction in patients who are not candidates for a transverse rectus abdominalis myocutaneous flap and revision surgery for the contralateral breast remains challenging. We developed a novel breast reconstruction technique using a latissimus dorsi myocutaneous (LD m-c) flap set at the posterior aspect of the reconstructed breast, combined with an anatomical silicone breast implant (SBI), following tissue expander surgery. We performed the proposed technique in four patients, in whom the weight of the resected tissue during mastectomy was >500 g and the depth of the inframammary fold (IMF) was >3 cm. After over-expansion of the lower portion of the skin envelope by a tissue expander, the LD m-c flap was transferred to cover the lower portion of the breast defect and to achieve a ptotic contour, with the skin paddle set at the posterior aspect of the reconstructed breast. An SBI was then placed in the rest of the breast defect after setting the LD m-c flap. No major complications were observed during the follow-up period. The proposed technique resulted in symmetrical and aesthetically satisfactory breasts with deep IMFs, which allowed proper fitting of the brassiere, following large and ptotic breast reconstruction.

Natural History of Seroma Following the Immediate Latissimus Dorsi Flap Method of Breast Reconstruction

BACKGROUND

The latissimus dorsi (LD) flap procedure remains a popular and useful breast reconstruction tool in China and Western countries, and donor site seroma formation is the main complication. This study was conducted in Chinese patients to determine whether stable cases of seromas would resolve without treatment.

METHODS

A.

retrospective review of 45 consecutive cases of immediate breast reconstruction with LD flap from April 2012 to February 2017 was conducted. The scope of the seroma was demarcated with a marker pen, and cases that remained stable over time (i.e. the size of the seroma did not increase) were observed without treatment. The measured outcomes included the incidence of seromas, the volume and duration of postoperative wound drainage, and other demographic characteristics.

RESULTS

Twenty-four patients (53.3%) developed a seroma at the donor site. Of these, 21 patients (87.5%) did not require treatment, and the seroma resolved over time. The mean duration of a sustained seroma was 6.8 ± 1.4 weeks (range: 4-9 weeks).

CONCLUSIONS

This study observed the scope and progression of the seromas and found that seromas at the LD donor sites resolved over time without treatment.

Trends in breast reconstruction: Implications for the National Health Insurance Service

Background

Breast reconstruction has become more common as mastectomy has become more frequent. In Korea, the National Health Insurance Service (NHIS) began covering breast reconstruction in April 2015. This study aimed to investigate trends in mastectomy and breast reconstruction over the past 10 years and to evaluate the impact of NHIS coverage on breast reconstruction.

Methods

Nationwide data regarding mastectomy and breast reconstruction were collected from the Korean Breast Cancer Society registry database. Multiple variables were analyzed in the records of patients who underwent breast reconstruction from January 2005 to March 2017 at a single institution.

Results

At Seoul National University Hospital, the total number of reconstruction cases increased 13-fold from 2005 to 2016. The proportion of immediate breast reconstruction (IBR) cases out of all cases of total mastectomy increased from 4% in 2005 to 52.0% in 2016. The proportion of delayed breast reconstruction (DBR) cases out of all cases of breast reconstruction and the overall number of DBR cases increased from 8.8% (20 cases) in 2012 to 18.3% (76 cases) in 2016. After NHIS coverage was initiated, the proportions of IBR and DBR showed statistically significant increases (P<0.05). Among the IBR cases, the percentage of prosthesis-based reconstructions increased significantly (P<0.05), but this trend was not found with DBR. Total mastectomy became significantly more common after the expansion of NHIS coverage (P<0.05).

Conclusions

Over the last decade, there has been an increase in mastectomy and breast reconstruction, and the pace of increase accelerated after the expansion of NHIS coverage. It is expected that breast reconstruction will be a routine option for patients with breast cancer under the NHIS.

Adherence to best practice consensus guidelines for implant-based breast reconstruction: Results from the iBRA national practice questionnaire survey

INTRODUCTION

The 2008 National Mastectomy and Breast Reconstruction Audit demonstrated marked variation in the practice and outcomes of breast reconstruction in the UK. To standardise practice and improve outcomes for patients, the British professional associations developed best-practice guidelines with specific guidance for newer mesh-assisted implant-based techniques. We explored the degree of uptake of best-practice guidelines within units performing implant-based reconstruction (IBBR) as the first phase of the implant Breast Reconstruction Evaluation (iBRA) study.

METHODS

A questionnaire developed by the iBRA Steering Group was completed by trainee and consultant leads at breast and plastic surgical units across the UK. Simple summary statistics were calculated for each survey item to assess compliance with current best-practice guidelines.

RESULTS

81 units from 79 NHS Trusts completed the questionnaire. Marked variation was observed in adherence to guidelines, especially those relating to clinical governance and infection prevention strategies. Less than half (n = 28, 47%) of units obtained local clinical governance board approval prior to offering new mesh-based techniques and prospective audit of the clinical, cosmetic and patient-reported outcomes of surgery was infrequent. Most units screened for methicillin-resistant staphylococcus aureus prior to surgery but fewer than 1 in 3 screened for methicillin-sensitive strains. Laminar-flow theatres (recommended for IBBR) were not widely-available with less than 1 in 5 units having regular access. Peri-operative antibiotics were widely-used, but the type and duration were highly-variable.

CONCLUSIONS

The iBRA national practice questionnaire has demonstrated variation in reported practice and adherence to IBBR guidelines. High-quality evidence is urgently required to inform best practice.

Postmastectomy Breast Reconstruction With the Totally Autologous Latissimus Dorsi Flap in the Thin, Small-Breasted Woman: Give It More Thought!

Introduction: Thin women have fewer autologous tissue breast reconstructive options than their higher body mass index counterparts-due to a lack of adequate donor sites. They are therefore usually offered expander/implant techniques. The total autologous latissimus dorsi flap is generally used in "well-padded" individuals, as they have enough fat on their back on which a completely autologous reconstruction could be based. When implant-based reconstruction is contraindicated (for instance due to planned adjuvant radiotherapy) or unacceptable to the patient, the total autologous latissimus dorsi flap can provide adequate tissue volume by utilizing the additional back fat deposits even in the thin, small-breasted patient. This option is often overlooked by many surgeons. Our case series assesses indications and patient and surgeon satisfaction with the cosmetic outcome of this technique. Methods: The oncological and clinical details of 6 patients with breast cancer who underwent total autologous latissimus dorsi myocutaneous flap immediate breast reconstruction by a single surgeon over an 8-year period were reviewed. An objective assessment of satisfaction with the cosmetic result was made by whether any additional surgical interventions (ipsilateral fat grafting/implant augmentation or contralateral liposuction/ reduction) were needed or not. A subjective assessment of breast symmetry by the surgeon using photographic records was also undertaken. The aesthetic outcomes were also objectively quantified using the BCCT.core software, initially developed for assessing the results of breast conservation surgery. Results: All 6 patients had small breasts and a low or normal body mass index. The mastectomies were performed for invasive carcinoma (n = 3) and extensive high-grade ductal carcinoma in situ (n = 3). Four had axillary surgery (2 sentinel lymph node biopsies and 2 axillary clearances), and 3 received adjuvant radiotherapy. All were happy with their reconstructive outcomes, and none suffered major postoperative complications or disease recurrence. None requested or needed any subsequent ipsilateral adjustment or contralateral symmetrizing procedures. Subjectively, the reconstructions provided acceptable or excellent cosmetic results. The cosmetic results were categorized as excellent or good on the BCCT.core scoring system. Conclusion: This underutilized method of totally autologous breast reconstruction in thinner patients with lower body mass indexes yielded good, well-accepted cosmetic results without recourse to adjustment procedures, contralateral balancing surgery, or complex microvascular surgery. We recommend that the total autologous latissimus dorsi flap should be given more consideration when planning immediate breast reconstruction in this challenging group of thin, small-breasted patients.

Radiation Therapy and Immediate Breast Reconstruction: Novel Approaches and Evidence Base for Radiation Effects on the Reconstructed Breast

Patients who undergo breast reconstruction experience higher complication rates if they have had a history of radiotherapy. However, implant-based reconstruction confers significantly higher complication and reconstruction failure rates compared with autologous reconstruction. This article analyses the factors that contribute to the complications of the different breast reconstruction modalities and the strategies described to mitigate these problems.

Measuring the patient perspective on latissimus dorsi donor site outcomes following breast reconstruction

BACKGROUND

There is little evidence about the long-term donor site outcome of latissimus dorsi breast reconstruction and no patient-reported outcome measures designed specifically for the procedure.

METHODS

A prospective cohort of breast cancer patients having latissimus dorsi reconstruction after a mastectomy was recruited from 270 hospitals in the United Kingdom. An 18-month follow up questionnaire containing two novel scales was sent to consenting patients. The prevalence of aesthetic and functional morbidity at the donor site was described. The two new scales were refined using the Rasch measurement model and subsequently validated.

RESULTS

1,096 women completed the new scales. 78% of patients reported that no back appearance issues had bothered them "most of the time" or "all of the time" in the past two weeks. The equivalent figure for functional morbidity was 60%. Four items were eliminated following initial psychometric testing. This produced an 8-item Back Appearance scale and an 11-item Back and Shoulder Function scale. Both scales showed adequate fit to the Rasch measurement model. Higher levels of aesthetic and functional bother were observed for completely autologous procedures versus those where latissimus dorsi reconstruction was used to cover an implant (p <0.05). Higher levels of aesthetic bother were observed in women who had suffered a perioperative complication at the donor site (p = 0.003).

CONCLUSION

These results can inform patients of the morbidity associated with latissimus dorsi reconstruction. The new scales can be used to compare groups undergoing different variations of the procedure and to monitor individual patients.

Adipose-Derived Stem Cells in Novel Approaches to Breast Reconstruction: Their Suitability for Tissue Engineering and Oncological Safety

Adipose-derived stem cells (ADSCs) are rapidly becoming the gold standard cell source for tissue engineering strategies and hold great potential for novel breast reconstruction strategies. However, their use in patients with breast cancer is controversial and their oncological safety, particularly in relation to local disease recurrence, has been questioned. In vitro, in vivo, and clinical studies using ADSCs report conflicting data on their suitability for adipose tissue regeneration in patients with cancer. This review aims to provide an overview of the potential role for ADSCs in breast reconstruction and to examine the evidence relating to the oncologic safety of their use in patients with breast cancer.

Infection Prophylaxis for Breast Implant Surgery: Could We Do Better?

Objective: Infective complications following breast implant surgery may result in implant removal. This causes patient distress and is costly to treat. A range of precautions is undertaken at the time of surgery to reduce infection, with varying levels of supporting evidence. This study aimed to determine how frequently and consistently infection prevention precautions are used during breast implant surgery. Methods: Multicenter observational study of surgical practice with real-time data collection during breast implant surgery. Results: From 7 NHS breast units, 121 implant procedures were assessed in 94 patients under the care of 22 consultant surgeons. The commonest procedure was immediate reconstruction (58%; 70/121). All patients were methicillin-resistant Staphylococcus aureus (but not methicillin-sensitive Staphylococcus aureus) screened. Antibiotics were given at surgery in all cases; 92% (85/94) received postoperative antibiotics. Other precautions included closed glove technique (67%; 63/94), door signs to reduce theater traffic (72%; 68/94), glove changing prior to implant handling (98%; 119/121), laminar air flow theaters (55%; 52/94), disposable drapes (94%; 88/94) and gowns (74%; 70/94), and cavity washing (89%; 108/121). Among the 14 consultants evaluated on more than 1 procedure (range, 2-22; median = 5), only 1 consistently used exactly the same precautions when siting an implant. Conclusion: Despite national guidance, infection prevention measures are not applied consistently during breast implant surgery, with variability between surgeons and within individual surgeon's practice. The introduction of an infection prevention checklist for all breast implant procedures could improve the reliability with which these precautions are undertaken.

Subcutaneous implant breast reconstruction: Time to reconsider?

Improvements in breast surgery techniques such as skin and nipple preserving mastectomy and innovative prosthetics (implants, acellular dermal matrices and meshes) is renewing interest in subcutaneous (pre-pectoral) implant reconstruction. The aim of this paper is to review the current literature in an attempt to provide a rationale that may support a return to subcutaneous implant placement, so minimising the pain and functional problems resulting from submuscular breast reconstruction.

Over surgery in breast cancer

Breast surgery remains the original and most effective 'targeted' therapy: excision of early cancer is curative and for more advanced disease surgery improves local disease control. However in well intentioned pursuit of cure and local disease control, some cancers are over-treated resulting in major physical and emotional morbidity. Less breast surgery is safe, as evidenced by steady reductions in mortality and local recurrence; earlier diagnosis and widespread use of systemic therapies and radiotherapy have allowed more conservative surgery. As tumour biology dictates cancer outcomes not surgery extent, surgery can safely be 'minimum required' rather than 'more is better' with the focus on removal of disease rather than healthy tissue. Surgeons can reduce the burden of surgery further but it is important that less surgery is not over-compensated by more radical or unnecessary systemic therapies and/or radiotherapy with their own toxicities and morbidity. We all need to be alert to the potential drivers of over treatment and over surgery such as failure to work within a multidisciplinary team, failure to design a multimodality treatment plan at diagnosis or overuse of novel assessment technologies of uncertain clinical utility. Pursuit of wide margins and the removal of the contra-lateral healthy breast for marginal risk-reduction gains are also to be discouraged as is routine local/regional surgery in stage 4 disease. The surgeon has a pivotal role in minimizing breast surgery to what is required to achieve the best oncological, functional and aesthetic outcomes.

Infection prevention in breast implant surgery - A review of the surgical evidence, guidelines and a checklist

INTRODUCTION

As a result of increasing use of implant-based breast reconstruction, complications such as infection are being encountered more frequently. Surgical Site Infections (SSIs) cause morbidity for the patient, can lead to capsular contracture or implant loss and are costly to healthcare systems. National Guidelines suggesting methods to reduce SSI related complications have been produced, but are limited in the scope of interventions covered and underlying evidence presented.

METHODS

We performed a literature review encompassing a wide variety of possible SSI prevention strategies. We aimed to present summaries of the available evidence and give pragmatic recommendations as to their validity to use as guidelines for infection prevention strategies for implant-based breast reconstruction.

RESULTS

A lack of high quality data relating to the benefit of SSI prevention strategies in implant-based breast reconstruction exists. Many papers relate to orthopaedic implant surgery, or clean surgery in general. Following review of the evidence, sufficient data exists to support use of perioperative antibiotics at implant-based breast reconstruction, with continuation for an extended period in "high risk" patients. Alcohol containing skin preparations should be used over aqueous solutions. Laminar air flow use is suggested. Theatre traffic should be kept to a minimum, as should duration of operative procedure. The implant pocket should be washed prior to implantation. Double gloving and conductive warming are also endorsed.

CONCLUSIONS

We have produced a perioperative "Theatre Implant Checklist" for SSI prevention in implant-based breast surgery, with a set of pragmatic up to date guidelines, which allows the reader to evaluate the evidence upon which our recommendations are based.
