Breast reconstruction after mastectomy: A ten-year analysis of trends and immediate postoperative outcomes

Intraoperative Predictors of Salvage in Infected Breast Implants: A Retrospective Study

BACKGROUND

Infectious complications associated with implant-based breast reconstruction (IBBR) can be devastating and may lead to reconstructive failure. Although there are known demographic risk factors for reconstructive failure, few studies have identified intraoperative findings that predict failure after attempted salvage.

OBJECTIVES

The objective of this study was to identify intraoperative findings in infected breasts that might be predictive of implant failure.

METHODS

In total, 837 patients undergoing IBBR between January 2017 and July 2023 were included. Intraoperative records of patients who developed a major infection were reviewed. Reconstructive salvage denoted any intervention not resulting in explantation. Failure denoted explantation.

RESULTS

Of 837 patients, 8% developed a major infection (n = 71). Within this group, 8% had successful treatment with intravenous antibiotics alone, 38% were salvaged after operative intervention, 28.2% failed without salvage attempt, and 25.4% underwent salvage attempt but ultimately failed. Overall, the rate of reconstructive failure was 53.5% and the rate of implant salvage was 46.5%. A total of 51% of patients returning to operating room were found to have unincorporated acellular dermal matrix (ADM). Seventy-eight percent of patients undergoing intervention had a positive culture, most commonly methicillin-susceptible Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, Serratia, Enterobacter, Pseudomonas or Proteus. Unincorporated ADM was significantly associated with reconstructive failure (odds ratio 5.4, P = .003). Serratia infection, hematoma, and gram-negative infection were associated with implant failure, but these findings did not achieve statistical significance.

CONCLUSIONS

Presence of unincorporated ADM was associated with eventual implant failure. Surgeons should be aware that this finding may portend poor outcomes for patients. These results may be helpful to intraoperative decision-making.

Impact of Regional Surgeon Competition on Use, Cost, and Outcomes of Breast Reconstruction in the United States

BACKGROUND

Breast reconstruction following mastectomy is underused in the United States. Evidence suggests that more competitive hospital markets offer increased access to procedural care across specialties. This study aimed to determine the impact of regional plastic surgeon competition on use, outcomes, and cost of breast reconstruction following mastectomy for breast cancer.

METHODS

The authors conducted a retrospective cross-sectional analysis using MarketScan claims data from 2009 to 2020. The Herfindahl-Hirschman Index, a measure of market concentration, was calculated using the sum of squares of the proportion of breast reconstruction cases performed by each surgeon in a metropolitan statistical area. Multivariable logistic regression was used to identify differences in rates, outcomes, and costs of reconstruction by the Herfindahl-Hirschman Index.

RESULTS

Odds of receiving breast reconstruction within 2 years of mastectomy were higher for those in moderately competitive (OR, 1.51 [95% CI, 1.37 to 1.66]; P < 0.001) or competitive (OR, 1.71 [95% CI, 1.58 to 1.86]; P < 0.001) regions compared with noncompetitive regions. Patient out-of-pocket costs decreased when comparing moderately competitive regions with noncompetitive regions (-$67.38 [95% CI, -$88.65 to -$46.11]; P = 0.007), and decreased further when comparing competitive with noncompetitive regions (-$113.06 [95% CI, -$137.00 to -$89.12]; P = 0.02). No linear association between total, surgeon, or facility cost and market competition strata was identified.

CONCLUSIONS

Greater competition among surgeons is associated with improved access to reconstructive surgery, but no difference in cost. Application of this evidence may include system-level strategies to bolster care coordination, while targeting drivers of cost, such as hospitals and hospital systems, through policy.

Patient Satisfaction After 3D Nipple-Areolar Complex Tattooing: A Case Series of Hispanic Women Following Breast Reconstruction Surgery

BACKGROUND

Breast cancer is a prevalent cancer worldwide, leading many women to undergo mastectomy and breast reconstruction surgery. Nipple-areolar complex (NAC) reconstruction is critical in achieving aesthetic and psychological satisfaction. Recently, 3-dimensional (3D) NAC tattooing has become an option for this purpose.

OBJECTIVES

The aim of this study was to evaluate patient-reported outcomes for satisfaction among Hispanic women who underwent NAC reconstruction with 3D tattooing after breast reconstruction.

METHODS

Data were collected from a retrospective database covering a number of academic settings between 2014 and 2024. Participants were Hispanic women aged 32 to 60 years who had undergone various NAC reconstruction techniques. Follow-up was conducted no more than 6 months after surgery, utilizing the BREAST-Q version 2.0 questionnaire to measure satisfaction in 2 groups: Group 1, in which patients received alternative NAC reconstruction methods; and Group 2, which received 3D NAC tattooing.

RESULTS

Patients who underwent 3D NAC tattooing (Group 2) demonstrated increased psychosocial well-being, with a mean [standard deviation] score of 84.73 [8.56]. Regarding surgeon experience, Group 2 achieved a mean score of 86.21 [10.33], which was lower than the Group 1 mean of 88.70 [10.78]. Notably, Group 2 expressed greater satisfaction with nipple reconstruction, with a mean score of 3.73 [0.44] compared with the Group 1 mean score of 3.48 [0.65].

CONCLUSIONS

The findings indicate that 3D NAC tattooing may enhance aesthetic outcomes of the NAC and psychosocial well-being in Hispanic women. This highlights the importance of incorporating unique techniques in breast reconstruction and the need for a multidisciplinary approach.

Immediate Breast Reconstruction After Mastectomy for Cancer Among US Military Health System Beneficiaries

BACKGROUND

In the Military Health System (MHS), women with breast cancer may undergo surgical treatment in military hospitals (direct care) or in the civilian setting via the insurance benefit (private sector care). We conducted this study to determine immediate breast reconstruction rates among women undergoing mastectomy for cancer in the MHS by setting of care.

METHODS

Using the linked Department of Defense's Central Cancer Registry and MHS Data Repository, the Department of Defense's medical claims database, we identified adult women who underwent mastectomy for breast cancer from 1998 to 2014. Patients were then subgrouped by setting of care (direct vs private sector care). The primary outcome was the rate and type of immediate breast reconstruction. Regression models were constructed to determine factors associated with receipt of immediate breast reconstruction.

RESULTS

The final sample included 3251 women who underwent mastectomy for cancer in the direct (67.0%) or private sector care (32.6%) settings. The overall rate of immediate breast reconstruction was 29.9% with an upward trend noted throughout the study ( P < 0.001). Overall, implant-based reconstruction (81.4%) was more common than tissue-based reconstruction (18.6%). Compared with direct care, the immediate breast reconstruction rate was significantly higher in the private sector care setting (49.3% vs 20.5%, P < 0.001) despite accounting for differences in clinical characteristics (adjusted odds ratio = 4.51, 95% confidence interval [3.72-5.46]).

CONCLUSIONS

Immediate breast reconstruction in the direct care setting lags that in the civilian community during the study time period. Further research is needed to ascertain current immediate reconstruction rates and understand factors contributing to any differences in rates between care settings.

A study on the correlation between MRI-assessed breast volume asymmetry and patient satisfaction after immediate breast reconstruction in breast cancer patients

Immediate breast reconstruction provides breast cancer patients with a valuable opportunity to restore breast shape. However, post-reconstruction breast asymmetry remains a common issue that affects patient satisfaction. This study aims to quantify breast asymmetry after surgery using magnetic resonance imaging (MRI) and assess its impact on both breast satisfaction and overall outcome satisfaction, offering scientific evidence to guide improvements in preoperative evaluation. We retrospectively collected MRI images and demographic characteristics from 98 patients who underwent unilateral immediate breast reconstruction. All patients underwent breast MRI scans post-reconstruction, and the MRI images were converted into 3D models using 3D Slicer software. The implant volumes were measured and compared with the actual implant volumes inserted during surgery to assess the accuracy of the MRI measurements. Breast symmetry after surgery was quantified using MRI-measured breast volumes, and patient satisfaction was analyzed through BREAST-Q questionnaires to explore the relationship between breast symmetry, post-reconstruction breast satisfaction, and overall outcome satisfaction. The implant volumes measured in the 3D reconstructed MRI images exhibited high concordance with the volumes recorded during surgery (r = 0.980, p < 0.001). Breast asymmetry values were significantly higher in the high BMI group compared to the low BMI group (P = 0.013), while the asymmetry ratio was significantly lower in the high weight group compared to the low weight group (P = 0.006). The asymmetry ratio showed a weak correlation with breast satisfaction (r = - 0.341, P = 0.002) and outcome satisfaction (r = - 0.371, P = 0.004). When grouped by low asymmetry (asymmetry > 10%), there was no significant difference in breast satisfaction (P = 0.054) or outcome satisfaction scores (P = 0.23) between the groups. However, in cases of high asymmetry (asymmetry ratio > 40%), breast satisfaction (P = 0.003) and outcome satisfaction scores (P = 0.005) were significantly lower in the asymmetry group compared to the symmetry group. Breast volume asymmetry after immediate breast reconstruction is associated with patient satisfaction, with a significant decrease in satisfaction when asymmetry exceeds 40%. This suggests that preoperative evaluation should focus on breast symmetry to improve post-reconstruction patient satisfaction and surgical outcomes.

Orchiectomy after torsion testis: Simultaneous prosthesis placement versus staged procedures

BACKGROUND/PURPOSE

Testicular torsion(TT) with unsalvageable testis has a significant psychosocial impact. Orchiectomy can be performed with optional testicular prosthesis(TP) placement, commonly deferred(dTP). Orchiectomy and simultaneous testicular prosthesis placement(sTP) may be a feasible and safe option and has been implemented in our department since 2018.

AIM

The authors aim to perform a reflective analysis of the patient's experience and assess the feasibility, safety, and satisfaction of the sTP, by comparing it with the dTP.

METHODS

All patients with TT and unsalvageable testis submitted to orchiectomy were included in the study. An anonymous questionnaire assessed the patients' experience. Those submitted to orchiectomy and TP placement were divided in sTP and dTP groups and their clinical details, satisfaction and quality-of-life were analyzed and compared.

RESULTS

Scrotal exploration due to TT was performed in 185 patients, 54 were submitted to orchiectomy and 37 placed a TP(17 sTP, 20 dTP). All dTP patients and 66.7% of those without TP, would prefer having a prosthesis placed at the time of the orchiectomy. No significant differences in clinical details and outcomes were found, except prosthesis position (higher in dTP, p = 0.011) and operative time (13 min longer in sTP, p = 0.015). Both groups reported being satisfied with the prosthesis. Only one patient regretted placing a prosthesis(in dTP).

CONCLUSION

The sTP approach is as safe and effective as dTP. The patients preferred the sTP, as it avoids a second operation and possibly by having a lower psychological impact.

Temporal Sequencing of Multimodal Treatment in Immediate Breast Reconstruction and Implications for Wait Times: A Regional Canadian Cross-Sectional Study

Introduction: Treatment of breast cancer requires a multimodal approach with numerous independent specialists. Immediate breast reconstruction (IBR) adds another layer of coordination to comprehensive breast cancer care. To optimize health outcomes for patients seeking IBR, it is essential to efficiently coordinate the temporal sequence of care modalities inclusive of reconstruction. Methods: In this cross-sectional study, patients undergoing IBR following complete or partial mastectomy at one health centre from 2015 to 2021 were included. Patients were categorized into two main groups defined by the first treatment modality received, namely surgery first and Neoadjuvant Chemotherapy. Primary outcome measures were wait times for diagnostic investigations, initiation of treatment, and transitions between therapeutic modalities. Results: Of 195 patients, 158 underwent surgery first, and 37 underwent neoadjuvant chemotherapy. Median wait time from first consultation to first treatment initiated in the neoadjuvant cohort was shorter by 11.5 days as compared to the Surgery First cohort (21.5 +/- 19 vs 33.0 +/- 28 days; P = 0.001). Twenty-three (82%) of the surgery first and 11 (38%) of the neoadjuvant cohort patients waited longer than 8 weeks for initiation of radiotherapy (P = 0.001). Following surgical intervention, the majority of patients failed to meet target benchmarks for transition to chemotherapy (n = 25, 53%) and transition to radiotherapy (n = 26, 93%; P < 0.001). Conclusion: Patients undergoing IBR may incur delays in the setting of upfront surgery and in transitioning to adjuvant therapies. In the setting of breast reconstruction, further efforts are required to achieve target wait-times in multimodal breast cancer care.

The Metamorphosis of Patient Priorities Throughout the Breast Reconstruction Process

BACKGROUND

Breast reconstruction is a lengthy, multistage process guided by patients. It is vital to understand how their goals vary over time to achieve optimal outcomes.

OBJECTIVES

This study aimed to evaluate how breast reconstruction patients' priorities changed throughout the reconstructive process.

METHODS

Fifty women who underwent immediate breast reconstruction completed a quality of life survey at their preoperative appointment, 3, 6, and 12 months after surgery, and then again 10 years later. Scores on the survey's subsections corresponded to different patient priorities: survival, restitution, symmetry, and enhancement. The relationship between time and survey-measured patient priorities was analyzed with mixed-effects regression models and Tukey's HSD (honestly significant difference) tests were performed to make pairwise comparisons between time points.

RESULTS

Survival scores decreased between 3 and 12 months after surgery (P < .001) before returning to baseline at long-term follow-up. Restitution scores were decreased only at 12 months postoperatively (T3 vs T0, T1, and T2, P < .001; T3 vs T4, P = .003). Symmetry scores increased from preoperatively to 6 months postoperatively (P < .001), and then fell back to baseline by month 12 (P < .001) and remained at that level at long-term follow-up. Enhancement scores increased from preoperatively to 12 months after surgery (P < .001), before returning to baseline at 10-year follow-up (T0 vs T4, P > .99; T3 vs T4, P < .001). Time had an overall significant effect on each subsection score (P < .001), but this relationship was restricted to certain time points.

CONCLUSIONS

In the year following immediate breast reconstruction, patients' concern over their physical health decreases while they become increasingly focused on enhancing the appearance of their reconstructed breasts. However, by 10 years after surgery, patients' priorities were virtually unchanged from their preoperative desires.

Treatment of Capsular Contracture in Previously Irradiated Breasts Implants and Expanders with the Use of Porcine Acellular Dermal Matrices: Outcomes and Complications

Background: Radiation therapy is a crucial component of breast cancer treatment. However, it is well known to increase the risk of unsatisfactory cosmetic outcomes and higher complication rates. The aim of this study is to provide further insight into the use of acellular dermal matrices (ADMs) for the prevention of capsular contracture. Materials and Methods: This single-center, retrospective study analyzed irradiated patients who underwent post-mastectomy, ADM-assisted implant reconstructions. Of the 60 patients included, 26 underwent expander-to-implant substitution after radiotherapy (Group A), while 34 required implant replacement due to capsular contracture following radiotherapy (Group B). The primary objective was to evaluate the effectiveness of ADMs in reducing reconstructive failures, complications, and capsular contracture after breast irradiation. Results: We recorded a total of 15 complications and four implant losses. Reconstructive failures were attributed to implant exposure in two cases, full-thickness skin necrosis in one case, and severe Baker grade IV contracture in one case. Both Group A and Group B showed a significant decrease in postoperative Baker grades. US follow-up was used to demonstrate ADM integration with host tissues over time. Conclusions: Based on our findings, the use of ADM in selected cases appears to be a viable option for treating and preventing capsular contracture in irradiated breasts. This approach is associated with relatively low complication rates, a low rate of reconstructive failure, and satisfactory cosmetic outcomes and can be applied both in breast reconstructed with implants and with expanders.

Risk of Bleeding Versus Venous Thromboembolism After Surgery for Breast Cancer: A National Surgical Quality Improvement Program Analysis

INTRODUCTION

Patients who undergo surgery for breast cancer are at risk for venous thromboembolism (VTE) and bleeding, which can lead to significant consequences on outcomes. This study examined factors related to VTE and bleeding risk in breast cancer surgery, with and without reconstruction. We also investigated the relationship between operative time and resident involvement on bleeding and VTE risk.

METHODS

Using the ACS-NSQIP database, patients who underwent mastectomy, implant, pedicled, or free flap reconstruction from 2005 to 2021 were identified. Resident involvement was available from 2007 to 2010. We fitted two logistic regressions to model the log odds of bleeding occurrence and VTE as linear functions of procedure type, controlling for age, body mass index, and comorbidities.

RESULTS

Implant reconstruction had significantly reduced 30-d incidence of bleeding, compared to those who underwent transverse rectus abdominus muscle flap (P < 0.001). Free flap was associated with a significant increase in bleeding but not VTE risk (P < 0.001; P = 0.132). Increase in operative time significantly increased the risk of bleeding and VTE (P < 0.001). For surgeries with resident involvement coded, there was no significantly increased risk of bleeding or VTE (P = 0.600; P = 0.766).

CONCLUSIONS

Implant reconstruction remains the procedure with the lowest risk of both bleeding and VTE. Free flap reconstruction did not show a significantly increased risk of VTE, potentially expanding reconstruction options for patients previously excluded from autologous reconstruction. Surgeons should be mindful of operative time, with re-evaluation of risk factors with each additional hour of surgery, irrespective of reconstruction type. Resident involvement in surgeries should continue to be encouraged by faculty.

Impact of Tissue Expander Surface Texture on Two-Stage Breast Reconstruction Outcomes: A Combined Analysis

BACKGROUND

With ongoing investigations of the impact of device texturing on breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL), studies have begun comparing complication profiles of tissue expanders. However, there is a paucity of timing and severity data of complications. The aim of this study was to provide a comparative survival analysis of postoperative complications between smooth (STEs) and textured tissue expanders (TTEs) in breast reconstruction.

METHODS

A single-institution experience with tissue expander breast reconstruction was reviewed for complications up to 1 year after second-stage reconstruction from 2014 to 2020. Demographics, comorbidities, operation-related variables, and complications were evaluated. Kaplan-Meier curves, Cox proportional hazard models, and a consensus-based ordinal logistic regression model were used to compare complication profiles.

RESULTS

Of 919 total patients, 600 (65.3%) received TTEs and 319 (34.7%) received STEs. There was increased risk of infection ( P < 0.0001), seroma ( P = 0.046), expander malposition ( P < 0.0001), and wound dehiscence ( P = 0.019) in STEs compared with TTEs. However, there was also a decreased risk of capsular contracture ( P = 0.005) in STEs compared with TTEs. Failure of breast reconstruction ( P < 0.001) and wound dehiscence ( P = 0.018) occurred significantly earlier in STEs compared with TTEs. Predictors for significantly higher severity complications included the following: smooth tissue expander use ( P = 0.007), shorter time to complication ( P < 0.0001), higher body mass index ( P = 0.005), smoking history ( P = 0.025), and nipple-sparing mastectomy ( P = 0.012).

CONCLUSIONS

Differences in the timing and severity of complications contribute to the safety profiles of tissue expanders. STEs are associated with increased odds of higher severity and earlier complications. Therefore, tissue expander selection may depend on underlying risk factors and severity predictors.

The influence of a previous implant-based breast reconstruction on postoperative sensation of the deep inferior epigastric artery perforator flap

BACKGROUND

Implants and DIEP flaps have different outcomes regarding postoperative breast sensation. When compared to the preoperative healthy breast, implant-based breast reconstruction (IBBR) negatively influences postoperative breast sensation. However, it is currently unknown whether a prior IBBR also influences postoperative sensation of a replacing DIEP flap. The goal of this cohort study is to evaluate the influence of an IBBR on the postoperative sensation of a replacing DIEP flap.

METHODS

Women were included if they received a DIEP flap reconstruction after mastectomy, with or without prior tissue expander (TE) and/or definitive breast implant. Sensation was measured at four intervals in 9 areas of the breast with Semmes-Weinstein monofilaments: T0 (preoperative, implant/no reconstruction), T1 (2-7 months postoperative, DIEP), T2 (± 12 months postoperative, DIEP), Tmax (maximum follow-up, DIEP). Linear mixed-effects models were used to investigate the relationship between an implant/TE prior to the DIEP flap and recovery of breast sensation.

RESULTS

142 women comprising 206 breasts were included. 48 (23.3%) breasts did, and 158 (76.7%) breasts did not have a TE/IBBR prior to their DIEP. No statistically significant or clinically relevant relationships were found between a prior implant/TE and recovery of DIEP flap breast sensation for the flap skin, native skin, or total breast skin at T1, T2, or Tmax. There were also no relationships found after adjustment for the confounders radiation therapy, BMI, diabetes, age, flap weight, follow-up, and nerve coaptation.

CONCLUSIONS

An implant/TE prior to a DIEP flap does not influence the recovery of postoperative breast sensation of the DIEP flap.

Screening chest wall ultrasound in the mastectomy patient

BACKGROUND

While there are clear guidelines regarding chest wall ultrasound in the symptomatic patient, there is conflicting evidence regarding the use of ultrasound in the screening of women post-mastectomy.

OBJECTIVE

To assess the utility of screening chest wall ultrasound after mastectomy and to assess features of detected malignancies.

METHODS

This IRB approved, retrospective study evaluates screening US examinations of the chest wall after mastectomy. Asymptomatic women presenting for screening chest wall ultrasound from January 2016 through May 2017 were included. Cases of known active malignancy were excluded. All patients had at least one year of clinical or imaging follow-up. 43 exams (8.5 %) were performed with a history of contralateral malignancy, 465 exams (91.3 %) were performed with a history of ipsilateral malignancy, and one exam (0.2 %) was performed in a patient with bilateral prophylactic mastectomy.

RESULTS

During the 17-month period, there were 509 screening US in 389 mastectomy patients. 504 (99.0 %) exams were negative/benign. Five exams (1.0 %) were considered suspicious, with recommendation for biopsy, which was performed. Out of 509 exams, 3 (0.6 %) yielded benign results, while 2 (0.39 %) revealed recurrent malignancy, with a 95 % confidence interval (exact binomial) of 0.05 % to 1.41 % for screening ultrasound. Both patients who recurred had previously recurred, and both had initial cancer of lobular histology.

CONCLUSION

Of 509 chest wall screening US exams performed in mastectomy, 2 malignancies were detected, and each patient had history of invasive lobular carcinoma and at least one prior recurrence prior to this study, suggesting benefit of screening ultrasound in these populations.

Risk factors for severe complications and salvage management in direct-to-implant immediate breast reconstruction: A retrospective study

Controversies regarding the risk factors affecting direct-to-implant (DTI) immediate breast reconstruction still exist. This study aimed to evaluate the risk factors for severe complications in DTI breast reconstruction and explore potential salvage management strategies. We conducted a retrospective review of 238 patients (240 breasts) who underwent DTI immediate breast reconstruction between 2011 and 2020. Multivariate logistic regression analyses were used to identify the risk factors predicting severe complications. Seventeen (7.08%) reconstructed breasts experienced severe complications, of which only 5 were successfully salvaged through surgical revision, while the others failed and resulted in implant removal. Multivariate analyses demonstrated that mesh use [odds ratio (OR) = 4.054, 95% confidence interval: 1.376-11.945, P = .011] and post-mastectomy radiotherapy (odds ratio = 4.383, 95% confidence interval 1.142-16.819, P = .031) were independent predictors of severe complications. Mesh use and post-mastectomy radiotherapy for breast reconstruction increase the risk of severe complications. Despite positive surgical treatment, the successful salvage rate was poor.

Testicular prostheses - impact on quality of life and sexual function

Orchiectomy is the recommended treatment for many testicular conditions. However, testicular prosthesis placement is not always performed for different reasons. In this study, we aimed to evaluate patients' opinions and the impact on sexual function and quality of life. This retrospective observational single-center study included patients who underwent orchiectomy between January 2014 and December 2020 at the Department of Urology, Braga's Hospital (Braga, Portugal), where testicular implants were always available and the decision to undergo the procedure was made fully independent of cost. Patients completed four questionnaires that assessed demographic data, satisfaction, self-esteem, and sexual function. Of the 96 patients who underwent orchidectomy, 59 replied to the questionnaires, and of these patients, 86.4% decided to undergo silicone-based testicular prostheses implantation. The remaining 13.6% refused the implant based on concerns about complications (37.5%), because they felt that it was unnecessary (37.5%), or because it was not offered by the doctor (25.0%). Overall, 96.1% of these patients were satisfied with the implant; however, 25.5% classified it as "too firm". No statistically significant differences were found in sexual function (all P > 0.05). However, it can be observed that there are more patients with prostheses presenting normal sexual activity compared to patients without prostheses (74.0% vs 50.0%), and none of them reported severe erectile dysfunction (0 vs 16.7%). Regarding self-esteem, both patients with and without prostheses present very similar average scores with no statistically significant differences. The present study highlights the highest level of satisfaction among patients who received testicular prostheses. Testicular prostheses implantation is a safe procedure that does not hamper sexual function after orchiectomy.

Postmastectomy radiotherapy in breast reconstruction: Current controversies and trends

Breast cancer is the most common cancer among women worldwide. Postmastectomy radiotherapy (PMRT) is an essential component of combined therapy for early-stage, high-risk breast cancer. Breast reconstruction (BR) is often considered for patients with breast cancer who have undergone mastectomy. There has been a considerable amount of discussion about the optimal approach to combining PMRT with BR in the treatment of breast cancer. PMRT may increase the risk of complications and prevent good aesthetic results after BR, while BR may increase the complexity of PMRT and the radiation dose to surrounding normal tissues. The purpose of this review is to give a broad overview and summary of the current controversies and trends in PMRT and BR in the context of the most recent literature available.

Machine Learning to Predict the Need for Postmastectomy Radiotherapy after Immediate Breast Reconstruction

Background

Post mastectomy radiotherapy (PMRT) is an independent predictor of reconstructive complications. PMRT may alter the timing and type of reconstruction recommended. This study aimed to create a machine learning model to predict the probability of requiring PMRT after immediate breast reconstruction (IBR).

Methods

In this retrospective study, breast cancer patients who underwent IBR from January 2017 to December 2020 were reviewed and data were collected on 81 preoperative characteristics. Primary outcome was recommendation for PMRT. Four algorithms were compared to maximize performance and clinical utility: logistic regression, elastic net (EN), logistic lasso, and random forest (RF). The cohort was split into a development dataset (75% of cohort for training-validation) and 25% used for the test set. Model performance was evaluated using area under the receiver operating characteristic curve (AUC), precision-recall curves, and calibration plots.

Results

In a total of 800 patients, 325 (40.6%) patients were recommended to undergo PMRT. With the training-validation dataset (n = 600), model performance was logistic regression 0.73 AUC [95% confidence interval (CI) 0.65-0.80]; RF 0.77 AUC (95% CI, 0.74-0.81); EN 0.77 AUC (95% CI, 0.73-0.81); logistic lasso 0.76 AUC (95% CI, 0.72-0.80). Without significantly sacrificing performance, 81 predictive factors were reduced to 12 for prediction with the EN method. With the test dataset (n = 200), performance of the EN prediction model was confirmed [0.794 AUC (95% CI, 0.730-0.858)].

Conclusion

A parsimonious accurate machine learning model for predicting PMRT after IBR was developed, tested, and translated into a clinically applicable online calculator for providers and patients.

Key factors in the decision-making process for mastectomy alone or breast reconstruction: A qualitative analysis

Breast cancer is the most common cancer to affect New Zealand women. Women diagnosed face several decisions regarding surgical treatment, including whether to undergo lumpectomy, mastectomy, or breast reconstruction. Reconstructive surgery adds an additional layer of complexity, with several reconstructive options, each associated with differing surgical and recovery times. Furthermore, surgical decisions are often made under time-pressure and significant diagnostic distress, therefore provision of good information to support decision-making is crucial to adequately inform women of their options. We interviewed 24 women who had undergone breast surgery within the preceding 12 months to assess the key factors leading to their decision to opt for their chosen surgical procedure. Interviews revealed that decision-making was complex and involved multiple factors. Women were ultimately confronted with assessing feminine identity versus survival. Whether opting for breast reconstruction or not, women were fearful of what surgery would involve and how their reconstructed breast or mastectomy scar might look following surgery. Shared decision-making between patient and clinician can mitigate this fear and provide women with a sense of autonomy over their health decisions. Provision of visual depictions of surgical outcomes was not routinely provided to those interviewed but was expressed as important to help women manage surgical expectations. Therefore our findings support the multi-modal presentation of diagnostic and treatment information to support decision-making. Likewise, women reported feeling unsupported in their decision not to undergo breast reconstruction, suggesting a need to develop resources to provide women with positive discussions about 'going flat'.

Impact of Adjuvant Radiotherapy on Free Flap Volume in Autologous Breast Reconstruction: A Scoping Review

In autologous breast reconstruction, a sufficient flap volume is fundamental to restore breast shape and ensure an aesthetic outcome. After mastectomy, postoperative irradiation is regularly indicated in the oncological treatment algorithm. When administering radiation therapy after autologous reconstruction, the tissue transferred is inherently irradiated. Although there is evidence that points to a reduction in flap volume after adjuvant radiotherapy, the data have been contradicting and inconclusive. To address this anecdotal evidence, we performed a scoping review of the current literature that addresses the effect of radiotherapy on breast flap volume. Six two-armed studies, comprising a total of 462 patients, reported on the effect of adjuvant radiotherapy on free flap volume changes. Of those, two studies found a significant negative impact of radiotherapy on free flap volume, while the other four studies did not. Reported flap volume changes ranged from no change to a reduction of 26.2%, measured up to two years postoperatively. The selected studies contain varying patient numbers, follow-up timepoints, types of flaps, and measuring methods, contributing to a relatively high heterogeneity. While we present some evidence suggesting a significant impact of adjuvant radiotherapy on breast flap volume, future studies are needed to further investigate this potential correlation.

Importance of Breast Sensation After Mastectomy: Evidence from Three Sources

Background

Every year, more than 90,000 U.S. women undergo mastectomy. More than 40% have reconstruction. Following reconstruction, most women experience persistent partial or complete numbness of the reconstructed breasts, and many experience pain. Yet, breast reconstruction procedures focus largely on esthetic outcomes with mixed impact on sensory outcomes and little attention to pain. This study examines whether and how breast sensation is important to women.

Materials and Methods

Conventional content analysis of extant qualitative data from a clinical registry (29 women with prior breast surgery for cancer, 2008-2022), a volunteer community sample (qualitative interviews with 6 women with and 5 without breast cancer, 2019), and from a Twitter social media survey (N = 32, 2022).

Results

Functions of the breast identified by women with and without cancer include breastfeeding, sexual function, and femininity. Five interrelated themes on the importance of breast sensation emerged among women with breast cancer history: sexual function, experience of partnered sex or relationship with one's sexual partner, breast embodiment, effect of breast pain on sexual function, and importance to psychological wellbeing. Women, advocates, and clinicians described a lack of patient-physician communication in this domain that exacerbates the negative impact of breast sensation loss on health and wellbeing.

Conclusions

Breast sensation is important to women following mastectomy, yet a gap exists in patient-physician communication about the impact of mastectomy and reconstruction on breast sensory function. Lessons for physicians, scientists, and skeptics are conveyed about why the basic integrity of women's bodies matters for practice and science.

Prophylactic Use of Negative Pressure Wound Therapy in High-risk Patients Undergoing Oncoplastic and Reconstructive Breast Surgery

Background

Negative pressure wound therapy (NPWT) has emerged as an adjunct to reduce wound complication rates in many surgical domains. This study investigated the prophylactic use of PICO NPWT in high-risk patients undergoing oncoplastic and reconstructive breast surgery.

Methods

This was a prospective multicenter national audit. The findings were compared against Association of Breast Surgery/British Association of Plastic, Reconstructive and Aesthetic Surgeons (ABS/BAPRAS) Oncoplastic Guidelines for best practice.

Results

Data from 267 patients were included from seven centers. All patients had at least one high-risk factor for postoperative wound complications, whereas 78 patients (29.2%) had more than one. Thirty-six patients (13.5%) developed postoperative wound complications. An estimated 16 (6%) developed skin flap necrosis, wound dehiscence occurred in 13 patients (4.9%), and 15 patients (5.6%) developed postoperative wound infection. Eleven patients (4.1%) required further surgery due to wound complications. In total, 158 patients underwent mastectomy with immediate implant reconstruction. Postoperative wound complication rate was comparable in this subgroup (n = 22; 13.9%). Implant loss rate was 3.8%, which was within the 5% target mentioned in the ABS/BAPRAS guidelines. The estimated total cost saving was US $105,600 (£84,613) and US $395.50 (£316.90) per patient. Wound infection rate (5.6%) was much lower than the 25% reported by both iBRA study and National Mastectomy and Breast Reconstruction Audit.

Conclusions

Our study suggests that prophylactic use of NPWT in oncoplastic and reconstructive breast surgery results in low rates of wound-related complications with associated healthcare cost benefits in patients with high-risk factors for wound-related complications. However, a prospective randomized control trial is required.

Bovine Acellular Dermal Matrix-Based Breast Reconstruction in Previously Irradiated Breasts: Complications and Outcomes From a Single-Center Experience

ABSTRACT

Radiation therapy is considered today an integral part of the management of breast cancer. However, radiotherapy significantly increases the incidence of total complications in breast reconstruction. Several procedures have been adopted to reduce complication rates in irradiated fields, including the use of acellular dermal matrices (ADMs). We conducted a retrospective analysis of our single-center experience with ADM-assisted implant-based reconstruction or revision surgeries for capsular contracture treatment in irradiated breasts. We divided our population into 4 groups based on prior surgical history: group A (previous quadrantectomy), group B (previous mastectomy and expander reconstruction), group C (previous mastectomy and implant reconstruction), and group D (prior quadrantectomy followed by mastectomy and implant reconstruction). At the European Oncology Institute in Milan, Italy, between June 2017 and April 2019, we identified 84 patients for a total of 86 irradiated breasts reconstructed with implant and ADM. We observed a total of 12 reconstructive failure, with the highest rate of failure in group B (16.6%) and in group D (15.38%). Overall, we recorded 22 total complications (24.4%): 12 major complications and 10 minor complications. The most common complication was infection, with 9 cases (10.4%), 6 of which were classified as severe and required implant removal. In group B, we observed the highest complication rate, both major and minor, with 7 of 42 patients (16.6%) experiencing each. Before reconstruction with ADM, the Baker grade ranged from 3 to 4, with a mean of 3.25. At the 2-year follow-up, the Baker grade ranged from 1 to 4, with a mean of 1.9. Surgeons were highly satisfied with the aesthetic result in 72.1% of cases, moderately in 8.1% and unsatisfied in 5.81%, and in 13.9%, the outcome was not assessable because of reconstructive failure. The worst aesthetic result was in group B. We observed significant reduction in capsular contracture in revision surgeries despite a moderately high rate of complications in previous quadrantectomy and radiotherapy. In our experience, breast reconstruction with implant and ADM is not the primary surgical indication in case of prior irradiation, but it can be considered as a valid alternative with reasonable safety profile, to be used in selected cases.

Deliberate Practice in DIEP Flap Breast Reconstruction: An Immediate and Sustained Decrease in Morbidity and Operative Time

BACKGROUND

Deep inferior epigastric perforator (DIEP) flaps are nuanced, multistep, complex procedures. Recent studies have hinted that operational flow can be a sensitive barometer for safety, efficiency, and overall outcomes. The authors critically assess the utility of implementing deliberate practice and process mapping as a research tool in the context of morbidity and operative time.

METHODS

Co-surgeons at a university hospital implemented deliberate practice and performed two prospective process analysis studies evaluating critical steps in DIEP flap reconstruction. During the 9-month period (June of 2018 to February of 2019), the flap harvest and microsurgery steps were assessed. During the 8-month period (January to August of 2020), the analysis was expanded to encompass the entire operation. To evaluate the immediate and sustained impact of process analysis, 375 bilateral DIEP flap patients were divided into eight consecutive 9-month intervals completed before, during, and after the two studies. Using risk-adjusted multivariate regressions, morbidity and operative time were compared between groups.

RESULTS

Time intervals completed before the first study had comparable morbidity and operative time. During the first study, there was an immediate 83.8% ( P < 0.001) decreased risk in morbidity. Operative time during the second study decreased by 2.19 hours ( P < 0.001). Morbidity and operative time continued to decrease until the end of data collection [62.1% decreased risk in morbidity ( P = 0.023) and decreased operative time of 2.22 hours ( P < 0.001)].

CONCLUSIONS

Deliberate practice and process analysis are powerful tools. Implementation of these tools can generate immediate and sustained decreases in morbidity and operative time for patients undergoing procedures such as DIEP flap breast reconstruction.

A comparison of presentations and outcomes of salvage versus non-salvage abdominal free flap breast reconstructions-Results of a 15-year tertiary referral centre review

INTRODUCTION

Salvage breast reconstruction with autologous tissue is becoming more prevalent due to a resurgence in implant-based procedures. The latter has caused a commensurate rise in failed or treatment-resistant prosthetic cases requiring conversion to free tissue transfers. Salvage reconstruction is often considered more challenging, owing to patient presentation, prior treatments and intraoperative difficulties. The aim of the study was to test this hypothesis by comparing outcomes of salvage versus non-salvage autologous microsurgical breast reconstructions in a retrospective matched cohort study.

METHODS

The demographics, risk factors, operative details and outcomes of patients who underwent free flap salvage of implant-based reconstructions by a single operator (2005-2019) were retrospectively evaluated. For each salvage reconstruction, the consecutive non-salvage abdominal free flap reconstruction was selected for comparison. The clinical outcomes including intraoperative blood loss, operative time, flap survival and complication rates were compared.

RESULTS

Of 442 microsurgical patients, 35 (8.0%) had salvage reconstruction comprising 41 flap transfers (29 unilateral, 6 bilateral) and 42 flaps (28 unilateral, 7 bilateral) in nonsalvage reconstruction. Deep inferior epigastric perforator (DIEP) flaps comprised the commonest autologous tissue used in both groups at 74% and 71% respectively. Most patients (83%) underwent salvage reconstruction for severe capsular contractures. There was a significant difference in radiation exposure between groups (salvage reconstruction 89%, non-salvage reconstruction 26%; p<0.00001). All 83 flaps were successful with similar reoperation rates and intraoperative blood losses. Unilateral salvage reconstruction took on average two hours longer than non-salvage reconstruction (p = 0.008). Overall complication rates were similar (p>0.05).

CONCLUSION

This 15-year study shows that despite salvage autologous free flap breast reconstruction requiring longer operation times, its intra and postoperative outcomes are generally comparable to non-salvage cases. Therefore, salvage breast reconstruction with free flaps provides a reliable option for failed or suboptimal implant-based reconstructions.

Blue-Blood Pig Thorax Model Increases Residents' Confidence in Internal Mammary Dissection

BACKGROUND

 Preparation of the recipient vessels is a crucial step in autologous breast reconstruction, with limited opportunity for resident training intraoperatively. The Blue-Blood-infused porcine chest wall-a cadaveric pig thorax embedded in a mannequin shell, connected to a saline perfusion system-is a novel, cost-effective ($55) simulator of internal mammary artery (IMA) dissection and anastomosis intended to improve resident's comfort, safety, and expertise with all steps of this procedure. The purpose of this study was to assess the effect of the use of this chest wall model on resident's confidence in performing dissection and anastomosis of the IMA, as well as obtain resident's and faculty's perspectives on model realism and utility.

METHODS

 Plastic surgery residents and microsurgery faculty at the University of Wisconsin were invited to participate. One expert microsurgeon led individual training sessions and performed as the microsurgical assistant. Participants anonymously completed surveys prior to and immediately following their training session to assess their change in confidence performing the procedure, as well as their perception of model realism and utility as a formal microsurgical training tool on a five-point scale.

RESULTS

 Every participant saw improvement in confidence after their training session in a minimum of one of seven key procedural steps identified. Of participants who had experience with this procedure in humans, the majority rated model anatomy and performance of key procedural steps as "very" or "extremely" realistic as compared with humans. 100% of participants believed practice with this model would improve residents' ability to perform this operation in the operating room and 100% of participants would recommend this model be incorporated into the microsurgical training curriculum.

CONCLUSION

 The Blue-Blood porcine chest wall simulator increases trainee confidence in performing key steps of IMA dissection and anastomosis and is perceived as valuable to residents and faculty alike.

Cost minimization in breast conserving surgery: a comparative study of radiofrequency spectroscopy and full cavity shave margins

BACKGROUND

In an effort to minimize positive margins and subsequent re-excision after breast conserving surgery (BCS), many providers and facilities have implemented either a Full Cavity Shave (FCS) approach or adding the MarginProbe Radiofrequency Spectroscopy System.

OBJECTIVE

We sought to create a functioning Pro-Forma for use by facilities and payers to evaluate and compare the cost savings of implementing FCS or MarginProbe based on personalized variable inputs.

METHODS

A decision tree demonstrating three possible surgical pathways, BCS, BCS + FCS, and BCS + MarginProbe was developed with clinical inputs for re-excision rate, mastectomy as 2nd surgery, rate of reconstruction, and rate of 3rd surgery derived by a literature review. A surgical pathway cost formula was created using the decision tree and financial inputs derived by utilizing the nation's largest database of privately billed health insurance claims and Medicare claims data (fairhealth.org). Using the surgical pathway formula and financial inputs, a customizable Pro-Forma was created for immediate cost savings analysis of BCS + FCS and BCS + Marginprobe using variable inputs. Costs are from the perspective of third-party payers.

RESULTS

Utilizing MarginProbe to reduce re-excisions for positive margins can be associated with better cost-savings than FCS due to the increased pathology processing costs by using an FCS approach. The reduction in re-excision provided by both FCS and MarginProbe offset their increased expense to various degrees with cost savings of each method improving as baseline re-excisions rates increase, until ultimately each may become cost-neutral or cost-prohibitive when compared to BCS alone. Our data suggest that in the privately insured population, MarginProbe provides a cost-savings over BCS alone when baseline re-excision rates are over 20% and that FCS becomes cost-saving when baseline re-excision rates are over 29%. For Medicare patients, MarginProbe provides a cost-savings when baseline re-excision rates exceed 34%, and FCS becomes cost-saving for re-excision rates over 52%. Our Pro-Forma allows an individual provider or institution to evaluate the cost savings of the FCS approach and/or utilization of the MarginProbe device such that the additional cost or cost-savings of utilizing one or both of these methods can be quickly calculated based on their facility's volume and baseline re-excision rate.

CONCLUSIONS

Our data suggest that utilizing either an FCS approach or the MarginProbe radiofrequency spectroscopy system may be a cost-saving solution to reducing the rate of re-excisions depending on a facility or practice's surgical volume and baseline re-excision rate. The degree to which each of these interventions provides an added cost or cost-savings to healthcare payers can be evaluated by utilizing the Pro-Forma outlined herein with customizable variable inputs.

Histologic and Immunohistochemical Evaluation of Human Breast Capsules Formed around Five Different Expander Surfaces

BACKGROUND

Polyurethane (PU) coating and implant texturization were designed to reduce the incidence of capsular contracture (CC), even if the link between surface type and CC remains unclear. To date, the etiopathogenetic aspects have not been fully clarified. The aim of this study was to evaluate capsules formed around five different breast expanders.

METHODS

Thirty patients were divided into randomized groups implanted with five different expanders: smooth, coated with PU foam (poly), with a low-microtextured, high-microtextured, and macrotextured surface (L-micro, H-micro, macro). Specimens of the capsules were removed at implant reconstruction and evaluated for morphology and immunohistochemistry expression of α-smooth muscle actin (α-SMA), collagen type I and III, CD68, CD34, and CD3. Remodeling Combined Index was also evaluated.

RESULTS

Expression of α-SMA was significantly increased in smooth capsules versus poly, low-microtextured, and high-microtextured groups ( P = 0.007; P = 0.010; P = 0.028), whereas the prevalence of collagen type I in smooth capsules and collagen type III in poly capsules identified a stable versus an unstable tissue. Remodeling Combined Index and α-SMA showed an inverted correlation. CD68 and CD34 cellular expression increased significantly in poly capsules with respect to smooth ( P < 0.001; P < 0.001) and macrotextured groups ( P < 0.001; P < 0.001). CD3 showed no significant difference among the groups.

CONCLUSION

In this human study, the authors observed that increased tissue remodeling and reduced myofibroblast activation, along with the inflammatory infiltration and neoangiogenesis, especially in the poly and low-microtextured groups, might promote the formation of an unstable and less fibrotic capsule, lowering the risk of CC.

Analysis of online materials regarding DIEP and TRAM flap autologous breast reconstruction

Online resources have become a mainstay for health information, and it is vital that such resources maintain accessible literacy levels to empower informed decision making. Previous studies have shown that the online resources regarding post-mastectomy breast reconstruction are of low readability; however, none have evaluated specific online resources regarding the most common procedures within autologous breast reconstruction, limiting analysis to the results of generic searches. This study sought to discover the readability of online, patient-directed resources regarding the Deep Inferior Epigastric Perforator (DIEP) and Transverse Rectus Abdominis Muscle (TRAM) flaps, the most utilized autologous flaps in breast reconstruction, using health literacy analysis. We hypothesized that the online materials regarding DIEP and TRAM flaps would yield literacy scores above the 6th-grade reading level, as recommended by the American Medical Association, despite previous literature and readability recommendations. Google searches for "DIEP breast reconstruction" and "TRAM breast reconstruction" were conducted. All patient-directed, non-sponsored websites found within the first three pages of the search underwent analysis using a variety of readability formulae. Both DIEP and TRAM resources were well above the 6th-grade reading level according to every metric used, and there was no significant difference in the reading level between the two procedures. Based on these results, significant work was needed to simplify the online resources to be more understandable for patients; these authors propose one method for such. In addition, the low readability of online resources suggests added emphasis on the need for surgeons to ensure that patients understand the medical information discussed during the presurgical consultations.

Patient Perspectives and Quality of Life after Breast Reconstruction and the Impact of Subsequent Revisions

There is limited research on the impact of revisional surgery after breast reconstruction on patient experience and postoperative quality of life (QoL).

Methods

Patients undergoing mastectomy with immediate implant-based or autologous free-flap breast reconstruction from 2008 to 2020 were reviewed. These patients were categorized by revisions (0-1, 2-3, and 4+) and surveyed on QoL metrics using BREAST-Q and Was It Worth It? (WIWI) questionnaires. BREAST-Q QoL, satisfaction, and WIWI metrics between revision groups were evaluated.

Results

Among 252 patients, a total of 150 patients (60%) underwent zero to one revisions, 72 patients (28%) underwent two to three revisions, and 30 patients (12%) underwent four or more revisions. Median follow-up was 6 years (range, 1-11 years). BREAST-Q satisfaction among patients with four or more revisions was significantly lower (P = 0.03), while core QoL domains (chest physical, psychosocial, and sexual well-being) did not significantly differ. Analysis of unplanned reoperations due to complications and breast satisfaction showed no significant difference in QoL scores between groups (P = 0.08). Regarding WIWI QoL metrics, four or more revisions were associated with a higher rate of worse QoL (P = 0.035) and worse overall experience (P = 0.001). Most patients in all revision groups felt it was worthwhile to undergo breast reconstruction (86%), would choose breast reconstruction again (83%), and would recommend breast reconstruction to others (79%).

Conclusions

Overall, a majority of patients undergoing revisions after breast reconstruction still have a worthwhile experience. Although reoperations after breast reconstruction do not significantly impact long-term BREAST-Q QoL domains, patients undergoing four or more revisions have significantly lower breast satisfaction, worse QoL, and a postoperative experience worse than expected.

Evidence for the use of peri- and post-operative antibiotic prophylaxis in autologous breast reconstruction: A systematic review

BACKGROUND

Autologous breast reconstruction has become standard of care, but there is no consensus on prophylactic antibiotic regimens for this surgical procedure. This review aims to present evidence on the best prophylactic antibiotic protocol to lower the risk of surgical site infections in autologous breast reconstructions.

METHODS

The search was performed in PubMed, EMBASE, Web of Science, and Cochrane Library on 25th of January 2022. Data on the number of surgical site infections, breast reconstruction type (pedicled or free flap) and reconstruction timing (immediate or delayed), as well as data on the type, dose, route of administration, timing, and duration of antibiotic treatment were extracted. All included articles were additionally assessed for potential risk of bias by using the revised RTI Item Bank tool.

RESULTS

12 studies were included in this review. No evidence is found that giving post-operative antibiotics for a prolonged period longer than 24 h after surgery is useful in lowering infection rates. This review could not distinguish between the best choice of antimicrobial agent.

DISCUSSION

Although this is the first study that collected current evidence on this topic, the quality of evidence is limited due to a small number of available studies (N = 12) with small study populations. The included studies have high heterogeneity, no adjustment for confounding, and interchangeably used definitions. Future research is highly recommended with predefined definitions, and a sufficient number of included patients.

CONCLUSION

Antibiotic prophylaxis up to a maximum of 24 h is useful in lowering infection rates in autologous breast reconstructions.

Postmastectomy breast reconstruction for women with hereditary gastric and breast cancer syndrome

Post mastectomy reconstruction is nowadays an integral part of breast cancer treatment, usually performed in the immediate setting. Among women with hereditary gastric and breast cancer syndromes, three different scenarios can be identified. First, healthy women seeking for prophylactic mastectomies. Second, cancer patients requiring mastectomy at the tumor site and simultaneous risk reducing mastectomy of the healthy breast. Third, cancer patients who have been treated for primary cancer requiring risk reducing mastectomies in a further stage. In this paper, we present a schematic guide for reconstruction for each subpopulation of subjects and their peculiarities.

Our Experience Using Round Nano-Surface Ergonomix Implants for Breast Reconstruction: A Single-Center Retrospective Study

BACKGROUND

Round nano-surface Ergonomix (Motiva, Establishment Labs; Alajuela, Costa Rica) implants were developed to address concerns regarding capsular contracture and textured anatomical breasts implants.

OBJECTIVES

The authors describe their early experience with Ergonomix implants in breast reconstruction.

METHODS

The authors retrospectively reviewed the charts of 212 patients (321 breasts) who underwent breast reconstruction employing round nano-surface Ergonomix implants between June 2017 and December 2020. Patients were followed for at least 12 months postoperatively. Demographics, surgical data, and postoperative surgical outcomes were recorded. Postoperative physical well-being and satisfaction with the breasts and implant were evaluated with Breast-Q questionnaires.

RESULTS

Of 211 patients, 75.4% had surgery due to cancer, and 24.6% underwent prophylactic surgery. Major complications occurred in 21 breasts (6.5%), of which 20 underwent revision operations. Reconstruction failed in 1 case (0.3%). Eleven breasts (3.4%) had minor complications. Immediate breast reconstruction, irradiated breasts, and smokers had higher rates of complications (P = 0.009, 0.02, 0.022, respectively). Rippling was more common in the pre-pectoral implant plane compared with sub-pectoral reconstruction (9% vs 1.2%, P = 0.001). Capsular contracture rate was 0.9% and occurred only in irradiated breasts. Implant malposition (inferiorly and laterally) occurred in 6.5% of the breasts, with no association between implant malposition and implant plane. Early follow-up demonstrated high patient satisfaction with the implant and breasts, and high scores in terms of patients' physical well-being.

CONCLUSIONS

Breast reconstruction employing the round nano-surface Ergonomix implant yielded low complication rates and high patient satisfaction. The transition from macro-textured to nano-surface implants has operative implications requiring a learning curve and surgical adjustments.

Using Clinical Measurements to Predict Breast Skin Necrosis: A Quantitative Analysis

BACKGROUND

Breast skin necrosis can lead to poor healing, reoperation, and unaesthetic reconstructive outcomes after mastectomy. Furthermore, the prolonged recovery can delay adjuvant oncologic regimens. This study aims to explore the role of breast surface area as a risk factor for mastectomy skin flap necrosis and to identify predictive clinical measurements.

METHODS

The authors retrospectively identified patients who underwent immediate breast reconstruction (N = 926 breasts) by 2 surgeons at a single institution between 2011 and 2021. Preoperative breast measurements such as nipple-notch (NN) distance, nipple-inframammary fold (NF) distance, chest width (CW), breast circumference (BC), and breast height (BH) were used to estimate breast surface area. Univariate analysis and receiver operating characteristic curves were used to determine predictive measurements and optimal cutoff values.

RESULTS

When approximated using either a cone without base or a half ellipsoid, larger surface area was a significant risk factor for mastectomy skin flap necrosis (P = 0.027 and P = 0.022, respectively). Larger NN, NF, CW, BC, and BH measurements were significant predictors of necrosis (P < 0.05). Surface area (cone without base) greater than 212 cm2, surface area (half ellipsoid) greater than 308 cm2, NN distance greater than 27 cm, NF greater than 8.5 cm, CW greater than 15 cm, BC greater than 29 cm, and BH greater than 10.5 cm are all values shown to increase the incidence of necrosis.

CONCLUSIONS

Larger breast surface area is an independent risk factor for breast skin necrosis. Preoperative breast measurements can be a useful adjunct for predicting necrosis in postmastectomy patients.

The Impact of Diabetes Mellitus on Breast Reconstruction Outcomes and Complications: A Systematic Literature Review and Meta-analysis

INTRODUCTION

As the incidence of breast cancer and diabetes rises, so does the number of patients with diabetes undergoing breast reconstruction (BR). Patients with diabetes are at a higher risk for post-operative complications. The current study examined the effects of diabetes on BR wound outcomes and overall complications post-operatively.

METHODS

This study followed the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. We conducted a systematic search and meta-analysis for published articles on the effects of DM on BR in January 2022 using the PubMed, MEDLINE, and Cochrane databases. Diabetes, breast reconstruction, and complications were used as keywords.

RESULTS

Forty-three studies were included in the qualitative synthesis, and five provided data to be included in the meta-analysis published between 2006 and 2020. A total of 19,731 patients (9.07%) had diabetes, whereas 197,812 patients had no diabetes. The results of the pooled outcomes revealed no differences in the risk of total flap loss (p = 0.892) and wound infection (p = 0.579,). Nevertheless, the risk of wound dehiscence was significantly higher among patients with diabetes than their non-diabetic counterparts (p < 0.0001).

CONCLUSION

Diabetic patients undergoing BR have a significantly higher risk of wound dehiscence. As a result of the adverse effects of diabetes status on BR outcomes, patients need to be counseled about optimizing their diabetes management before surgery. Because of the heterogeneity in our results, prospective randomized studies are needed to shed light on the consequences of diabetes mellitus in BR surgeries.

Long-Term Results after Autologous Breast Reconstruction with DIEP versus PAP Flaps Based on Quality of Life and Aesthetic Outcome Analysis

(1) Background: This work aimed to conduct a comparative study, providing long-term data about patient-reported outcome measures and donor site scar assessments, as well as an aesthetic evaluation of the reconstructed breasts in patients with DIEP versus PAP flap breast reconstruction. (2) Methods: This prospective, single-center, matched cohort study included a total of 36 patients after DIEP and PAP flap breast reconstruction. The evaluation was carried out using the Breast-Q and POSAS questionnaire, as well as the Breast Aesthetic Scale for cosmetic analysis, by four plastic surgeons. (3) Results: The postoperative Breast-Q evaluation revealed no significant differences between both patient groups for the categories of the physical well-being of the donor site, the physical well-being of the breast, and satisfaction with the breast. A scar evaluation of the donor site region showed equivalent results for the thigh and abdomen regions, concerning the overall opinion of the patients and the observers. There was no significant difference between both methods of reconstruction for all aspects of breast aesthetics. (4) Conclusions: Similar results for donor site morbidity, scar quality, and the aesthetic outcome of the breasts in both the DIEP and PAP patient groups have been demonstrated. Hence, in those cases suitable for both types of reconstruction, the decision can be based on factors such as patients' lifestyles, leisure activities, and preferences.

Predictors of Complications after Breast Reconstruction Surgery: A Systematic Review and Meta-analysis

Breast reconstruction (BR) is a unique surgical procedure that provides patients undergoing mastectomy with significant psychosocial and aesthetic benefits and has also become a crucial part of the treatment pathway for women with breast cancer. Due to methodological inadequacies and the absence of substantial risk factor analysis, no conclusion can be drawn about the correlation between risk variables and post-surgical complications in BR surgery. We aim to identify the potential risk factors associated with postoperative complications.

Methods

We queried MEDLINE and Cochrane CENTRAL from their inception to March 2022, for published randomized controlled trials and observational studies that assessed complications post-reconstruction procedure in breast cancer patients following mastectomy or evaluated at least one of the following outcomes of major or reoperative complications. The results from the studies were presented as odds ratios with 95% confidence intervals and were pooled using a random-effects model.

Results

Our pooled analysis demonstrated a significant correlation with BR postoperative complications and risk factors such as diabetes, hypertension, and obesity. Diabetes and the development of seroma were found to have a significant relationship. Risk variables such as age, radiotherapy, COPD, and smoking had no significant connection with 0-to-30-day readmission and 30-to-90-day readmission.

Conclusion

This meta-analysis shows that risk factors like age, smoking history, high blood pressure, and body mass index (BMI) have a big effect on complications after BR, and patients with risk factors have a high rate of developing infection.

The role of physical arm function and demographic disparities in breast cancer survivors’ ability to return to work

Purpose

Ability to return to work (RTW) is an important aspect of breast cancer that is limited for many survivors. With 90% survivorship in the USA, it is imperative that focus shifts toward the improvement of physical arm function to improve survivors’ ability to RTW. This narrative review discusses the role of physical arm function and demographic disparities in breast cancer survivor RTW.

Methods

Literature on physical function, arm function, and demographic disparities following breast cancer treatment and their implications for RTW is discussed.

Results

The ability to RTW is a key component of recovery for breast cancer survivors, but challenges and inequalities persist. Treatment effects can induce and prolong functional disability, affecting survivors’ ability to RTW. These effects may be compounded for survivors whose occupation requires physical arm function. The RTW landscape, including the occupations survivors have, the physical function required for job tasks, and availability of workplace accommodations, is also unclear. Additional demographic disparities (e.g., income, live in rural area) exist, but the extent to which these factors influence RTW is not well understood. More work is needed to understand the compounded impact of treatment effects, demographic disparities, and occupational factors on RTW. Multidisciplinary rehabilitation that includes occupational counseling and exercise is a promising approach, but widespread adoption in the US healthcare model presents an ongoing challenge. Areas for further research are highlighted.

Conclusion

There is an incomplete understanding of the effects of treatment on physical arm function and the role of demographic disparities on breast cancer survivor RTW.

Aesthetic Evaluation of Breast Reconstruction with Autologous Fat Transfer vs. Implants

Background

Autologous fat transfer (AFT) seems to be a new minimal invasive method for total breast reconstruction, yet how patients, surgeons, and laymen evaluate cosmesis is lacking. The aim of this study was to evaluate the aesthetic outcome of AFT (intervention group) for total breast reconstruction post-mastectomy, as compared to implant-based reconstruction (IBR) (control group).

Methods

A random and blinded 3D photographic aesthetic outcome study was performed on a selection of 50 patients, scored by three panels: plastic surgeons, breast cancer patients, and laymen. Secondary outcomes included agreement within groups and possible patient characteristics influencing scoring.

Results

Breast cancer patients and plastic surgeons did not differ in the aesthetic scores between the treatment groups. In contrast, the laymen group scored AFT patients lower than IBR patients (− 1.04, p < 0.001). Remarkably, mean given scores were low for all groups and overall agreement within groups was poor (ICC < 0.50). Higher scores were given when subjects underwent a bilateral reconstruction and if a mamilla was present.

Conclusion

Evaluation of aesthetic outcomes varies greatly. Hence, aesthetic outcome remains a very personal measure and this emphasizes the importance of thorough patient counseling including information on achievable aesthetic results before starting a reconstructive procedure.

Outcomes in Hybrid Breast Reconstruction: A Systematic Review

Background and Objectives: Lipofilling is a commonly performed procedure worldwide for breast augmentation and correction of breast contour deformities. In breast reconstruction, fat grafting has been used as a single reconstructive technique, as well as in combination with other procedures. The aim of the present study is to systematically review available studies in the literature describing the combination of implant-based breast reconstruction and fat grafting, focusing on safety, complications rate, surgical sessions needed to reach a satisfying reconstruction, and patient-reported outcomes. Materials and Methods: We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) throughout the whole review protocol. A systematic review of the literature up to April 2022 was performed using Medline, Embase, and Cochrane Library databases. Only studies dealing with implant-based breast reconstruction combined with fat grafting were included. Results: We screened 292 articles by title and abstract. Only 48 articles were assessed for full-text eligibility, and among those, 12 studies were eventually selected. We included a total of 753 breast reconstructions in 585 patients undergoing mastectomy or demolitive breast surgeries other than mastectomy (quadrantectomy, segmentectomy, or lumpectomy) due to breast cancer or genetic predisposition to breast cancer. Overall, the number of complications was 60 (7.9%). The mean volume of fat grafting per breast per session ranged from 59 to 313 mL. The mean number of lipofilling sessions per breast ranged from 1.3 to 3.2. Conclusions: Hybrid breast reconstruction shows similar short-term complications to standard implant-based reconstruction but with the potential to significantly decrease the risk of long-term complications. Moreover, patient satisfaction was achieved with a reasonably low number of lipofilling sessions (1.7 on average).

Donor-Site Morbidity and Quality of Life after Autologous Breast Reconstruction with PAP versus TMG Flap

The transverse myocutaneous gracilis (TMG) and the profunda artery perforator (PAP) flap are both safe choices for autologous breast reconstruction originating from the same donor region in the upper thigh. We aimed to compare the post-operative outcome regarding donor-site morbidity and quality of life. We included 18 patients who had undergone autologous breast reconstruction with a PAP flap (n = 27 flaps). Prospective evaluation of donor-site morbidity was performed by applying the same questionnaire that had already been established in a previous study evaluating TMG flap (n = 25 flaps) outcome, and results were compared. Comparison of the two patient groups showed equivalent results concerning patient-reported visibility of the donor-site scar and thigh symmetry. Still, the TMG group was significantly more satisfied with the scar (p = 0.015) and its position (p = 0.001). No difference was found regarding the ability to sit for prolonged periods. Donor-site wound complications were seen more frequently in the PAP group (29.6%) than in the TMG group (4.0%). Both groups expressed rather high satisfaction with their quality of life. Both flaps show minimal functional donor-site morbidity and high patient satisfaction. To minimize wound healing problems in PAP patients, thorough planning of the skin paddle is necessary.

Tissue Expander-Based Breast Reconstruction at a Major Safety-Net Hospital: Managing the Outsized Risk of Infection

Background

Immediate tissue expander (TE) breast reconstruction is reported to have the highest rate of postoperative infection among reconstructive modalities. The risk of infection is higher among patients treated at safety-net hospitals.

Objectives

The goal of this study was to identify significant contributing factors to the elevated infection risk at our major safety-net institution.

Methods

A retrospective chart review was conducted on all TE-based reconstruction patients with a diagnosis of postoperative infection between 2015 and 2019. Preoperative, perioperative, and postoperative risk factors for infection were determined and compared across patient and procedure demographics.

Results

Two hundred forty-three patients, for a total of 412 breast reconstructions, were included in our study. Significant preoperative selection factors were identified to contribute to the elevated risk of infection, including the following: older age, higher BMI, and diabetes. Significant intraoperative and postoperative contributing factors included greater mastectomy weight, larger TE's and intraoperative fill volume, and longer drain duration. Doxycycline treatment for infected patients resulted in a significantly higher rate of resolution.

Conclusions

Safety-net hospital population patients undergoing TE breast reconstruction are at higher risk for postoperative infection. Personal and procedural risk factors are identified. Balancing the benefits of immediate breast reconstruction with TEs with the elevated risk of postoperative infection remains challenging. Implementation of more stringent eligibility criteria may help mitigate the risk of infection.

Is There a Difference in the Diagnosis and Prognosis of Local Recurrence between Autologous Tissue and Implant-Based Breast Reconstruction?

Introduction

Breast reconstruction has become common after total mastectomy; however, certain types of breast reconstruction may be associated with delayed local recurrence or poor survival. Here, we investigated whether there are differences in the diagnosis and prognosis of local recurrence between autologous reconstruction and implant reconstruction.

Materials and Methods

A retrospective analysis was performed on patients undergoing breast cancer surgery with autologous tissue or immediate implant reconstruction in a single center (January 2003-December 2017). Patient data including the period from cancer surgery to local recurrence diagnosis, tumor size at the time of recurrence, and survival time after cancer surgery and recurrence detection were analyzed.

Results

There was a significant difference (p = 0.021) in the time from surgery to recurrence between the autologous tissue (1,246 days) and implant (909 days) groups. Recurrence tumor size did not differ (autologous: 1.00 cm² vs. implant: 0.90 cm²; p = 0.813). Survival time after surgery (p = 0.63) and recurrence detection (p = 0.74) did not statistically significant.

Conclusions

Statistical difference in the detection time was observed between autologous tissue and implant group. On the other hand, there is no difference in recurrence tumor size or survival time. A further study is necessary to identify the different detection time of local recurrence.

Breast Reconstruction: Necessity for Further Standardization of the Current Surgical Techniques Attempting to Facilitate Scientific Evaluation and Select Tailored Individualized Procedures Optimizing Patient Satisfaction

Background

Various breast cancer reconstruction methods and novel surgical techniques include autologous or allogenic procedures, which can increase patient's quality of life and provide options when dealing with patients seen as challenging clinical scenarios.

Summary

Our aim was to review the current literature and present published evidence on innovative standards in whole breast reconstruction. Advances in flap monitoring or newly published data regarding neurotization in breast reconstruction, arm lymphedema management, breast implant-associated anaplastic large cell lymphoma reconstruction treatment, and robotic surgery with regard to radiotherapy define innovative standards in the breast reconstruction setting. The role of meshes/acellular dermal matrix and fat grafting as well as optimal sequencing of postmastectomy radiotherapy in autologous and alloplastic breast reconstruction appear highly debatable also in expert panel meetings rendering further clinical research including RCTs imperative.

Key Messages

There is an abundance of novel available techniques, which mandate further standardization, facilitating scientific evaluation in an attempt to help surgeons select tailored procedures for each patient with the goal to promote informed decision-making in breast reconstruction.

The Failed Breast Implant in Postmastectomy Reconstruction: A Systematic Literature Review of Complications of Implant-Based Breast Reconstruction

BACKGROUND

Breast cancer is the most diagnosed malignant neoplasia of female patients worldwide in 2019. Survival has increased making it necessary to offer breast reconstructive procedures to improve quality of life and self-esteem. Implant-based breast reconstruction is the most common approach, making it necessary to quantify the associated complications.

METHODS

A systematic literature review of the PubMed, Cochrane, and Web of Science databases was performed. A total of 9608 citations were identified, and 44 studies met the inclusion criteria.

RESULTS

Studies included reported the incidence of complications either per patient or per breast leading consequently to 2 complication rates depending on the type of reporting. A total of 14.3% of patient-related and 28.8% of breast-related complications while undergoing implant-based reconstruction were reported.Among total complications reported, 72.6% of patient-related and 48.5% of breast-related complications were classified as major complications.A total of 37.6% of patients respectively 15.1% of breasts required prosthesis explantation due to severe complications. Depending on reporting, 9.7% of patients and 4% of breasts required autologous flap reconstruction due to reconstructive failure.

CONCLUSIONS

High complication and failure rates are associated with implant-based breast reconstruction. Lacking randomized controlled trials, the choice between implant-based and autologous breast reconstruction has to be made individually for each patient.
