Complications After Prepectoral Versus Subpectoral Breast Reconstruction in Patients Receiving Postmastectomy Radiation Therapy: A Systematic Review and Meta-Analysis.

Outcomes of immediate breast reconstructions can be influenced by postoperative radiotherapy. However, there is no clarity on the use of prepectoral or subpectoral breast reconstruction in the setting of postmastectomy radiation therapy (PMRT). We reviewed evidence on the complication rates of prepectoral and subpectoral breast reconstruction in women undergoing PMRT. PubMed, Web of Science, and Embase databases were scanned for studies comparing complication rates of prepectoral and subpectoral breast reconstruction with PMRT. All complications were pooled in a random-effect meta-analysis to obtain odds ratio (OR). Eight observational studies were included. Meta-analysis showed no difference in the risk of infections (OR: 1.22 95% CI 0.79, 1.88 I2=0%), implant loss (OR: 0.86 95% CI 0.50, 1.50 I2=14%), seroma (OR: 1.01 95% CI 0.43, 2.34 I2=50%), hematoma (OR: 0.44 95% CI 0.12, 1.71 I2=0%), wound dehiscence (OR: 0.95 95% CI 0.42, 2.17 I2=0%), and skin necrosis (OR: 0.61 95% CI 0.21, 1.75 I2=36%), contracture (OR: 0.46 95% CI 0.15, 1.48 I2=54%) and the need for revision surgeries (OR: 0.85 95% CI 0.45, 1.60 I2=15%) between the prepectoral and subpectoral groups. Data from observational studies indicates that in appropriately selected patients there may not be any difference in the risk of early complications with prepectoral or subpectoral breast reconstruction with PMRT. Current evidence is limited by the small number of studies, short follow-up and selection bias. There is a need for randomized controlled trials comparing the two approaches to obtain robust evidence on long-term outcomes.

Bilateral Implant-based Breast Reconstruction with Unilateral Radiotherapy: A Matched Cohort Study Comparing Nipple-sparing Mastectomy and Skin-sparing Mastectomy.

Nipple-sparing mastectomy (NSM) preserves the natural nipple-areola complex and entire native breast skin, with the goal of better cosmetic outcomes in breast reconstruction. In bilateral TE/implant-based reconstruction requiring unilateral postmastectomy radiotherapy (PMRT), progressive radiation-induced fibrosis can lead to increasing nipple asymmetry with cosmetic dissatisfaction. Thus, PMRT may ultimately negate the intended positive cosmetic value of NSM compared with skin-sparing mastectomy (SSM). This study compares (1) surgical complications, (2) patient satisfaction, and (3) aesthetic outcomes between NSM versus SSM in bilateral implant-based reconstruction with unilateral PMRT. This retrospective matched cohort study included consecutive NSM patients with bilateral TE/implant breast reconstruction + unilateral PMRT matched 1:2 to SSM group. Patients completed PMRT and TE exchange to implants. Demographics, oncologic stage, comorbidities, and complications were collected. Patient satisfaction was evaluated by BREAST-Q. Aesthetic outcomes were assessed by blinded reviewers with a five-point Likert scale. Among 58 patients who underwent bilateral TE/implant reconstruction with unilateral PMRT, 17 NSM patients were matched to 41 SSM patients by age, body mass index, and comorbidities. No significant differences existed in overall surgical complications and individual BREAST-Q questionnaire scores between cohorts. However, aesthetic outcomes scores were higher in SSM compared with NSM. Although NSM is generally associated with superior cosmetic outcomes compared with SSM, it has far less impact in bilateral implant-based breast reconstruction with unilateral PMRT due to the negative postradiotherapy effect on nipple symmetry.

A Scoping Review of Innervated Breast Reconstruction.

After breast surgery, patients experience significant alterations to breast sensation, which can diminish quality of life. Nerve coaptation technique, introduced in the 1990s, has gained traction in recent years. We performed a scoping review of the literature to determine the available outcomes in sensate breast reconstruction. The review was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews statement guidelines. EMBASE and PubMed databases were queried using standardized terminology. Studies were included if they reported original sensory outcomes following innervation techniques during breast reconstruction and were published from January 1, 1990, to April 18, 2022. Data extraction and analyses were performed on Microsoft Excel. From 602 screened articles, 27 studies met the inclusion criteria. Innervated autologous reconstructive procedures were described in 24, whereas the remaining 3 (all published after 2019) described direct reinnervation of the nipple-areola complex. Most (88.9%) of the studies comparing innervated versus noninnervated reconstruction reported improved sensory outcomes in at least 1 modality. Two studies investigated patient-reported outcomes using validated questionnaires, both of which reported improvement with innervated reconstruction. Sensate breast reconstruction has the potential to improve outcomes for patients. There is a recent progressive increase in studies involving direct nipple-areolar reinnervation. Larger, prospective studies are needed to better characterize the quality-of-life outcome using validated scales, as well as evaluate sensory and patient-reported outcomes with implant and autologous reconstruction.

Association of Neoadjuvant Chemotherapy With Postoperative Outcomes in Immediate Prepectoral Prosthetic Breast Reconstruction.

Neoadjuvant chemotherapy (NACT) followed by total mastectomy and immediate reconstruction has become an important strategy in the treatment of breast cancer. Although the safety of subpectoral implant-based breast reconstruction with NACT has been extensively evaluated, the safety in prepectoral reconstruction has not been clearly elucidated. We aimed to evaluate the association of NACT with immediate prepectoral breast reconstruction outcomes. A retrospective review of patients who underwent total mastectomy and immediate implant-based prepectoral breast reconstruction between May and December 2021 was conducted. Patients were categorized into 2 groups: those receiving NACT and those not receiving it. Postoperative complication rates were compared between the 2 groups. The independent association between NACT and the complication profiles was evaluated. Propensity score matching was also conducted. We analyzed 343 cases, including 85 who received NACT treatment and 258 who did not. Compared with the non-NACT group, the NACT group was younger, had a higher body mass index, and a higher rate of adjuvant radiotherapy. There were no differences in the rates of overall complications or type of complication between the 2 groups. In the multivariable logistic analyses, NACT did not show a significant association with the development of adverse outcomes. Similar results were observed in propensity score matching analyses. Our results suggest that receiving NACT may not have a significant detrimental effect on the postoperative outcomes of immediate prepectoral prosthetic reconstructions. Conducting prepectoral implant-based reconstruction in the setting of NACT might be safe and provide acceptable outcomes.

Abdominal closure with different oblique planes in island TRAM flaps: a method for achieving a better scar and contour of the donor site

Background An autologous abdominal flap can provide an aesthetically pleasing breast with a natural feel. However, contracted scars and hourglass contour deformities at the abdominal donor site can sometimes occur. These complications can reduce patient satisfaction and quality of life. Therefore, we performed different oblique plane closure of the abdominal donor site and evaluated the aesthetic scores in comparison with the conventional vertical single plane closure.Methods The procedures begin with a beveled incision down to the fascia level during transverse rectus abdominis muscle flap elevation. At the time of donor site closure, Scarpa’s fascia and the subcutaneous layers are sutured while being pulled downward. Sixty patients were divided into two groups: group A (single vertical plane closure) and group B (different oblique plane closure). Abdominal scars were scored by five reviewers using the scar scale.Results There were no significant differences in scores for vascularization, dog-ear presence, and umbilical shape of the scar between the two groups. However, group B showed marked improvements in flatness, contracture, and thickness of the scar surface. Notably, the different oblique plane closure in group B achieved much higher scores for the abdominal contour than group A.Conclusions The vertical single plane suture of the abdominal donor site may result in depressive contracture with poor cosmetic outcomes. The different oblique plane closure technique markedly improved the appearance of scars on the abdomen. This technique is likely to enhance patient satisfaction with both the breast and abdominal outcomes of breast reconstruction using an abdominal flap.

One versus two vein anastomoses in breast reconstruction with a profunda artery perforator flap-does it make a difference.

The profunda artery perforator (PAP) flap has gained popularity as a reliable alternative in breast reconstruction. Extensive research has focused on its vascular supply, dissection techniques, and broader applications beyond breast reconstruction. This study aims to investigate the correlation between the number of veins anastomosed for the PAP flap and postoperative complications. A retrospective study was conducted to evaluate the outcomes of breast reconstructions with PAP flaps at our institution between 2018 and 2022. A total of 103 PAP flaps in 88 patients were included. Statistical analysis was performed to compare outcomes between flaps with one vein anastomosis and those with two vein anastomoses. Patient characteristics, intra and postoperative parameters were analysed. One vein anastomosis was used in 36 flaps (35.0%), whereas two vein anastomoses were used in 67 flaps (65.0%). No significant differences were found in patient characteristics between the one vein and two vein groups. The comparison of ischemia times between flaps with one versus two veins revealed no statistically significant difference, with mean ischemia times of 56.2 ± 36.8 min and 58.7 ± 33.0 min, respectively. Regarding outcomes, there were no statistically significant differences in secondary lipofilling, revision of vein anastomosis, or total flap loss between the two groups. Fat necrosis was observed in 5 (13.9%) one vein flaps and 5 (7.5%) two vein flaps, indicating no statistically significant difference between the two groups (p = .313). In the one vein group, the most frequently employed coupler ring had a diameter of 2.5 mm. In the two vein group, the most prevalent combination consisted of a 2.0 mm diameter with a 2.5 mm diameter. Based on our study results, both one vein anastomosis and two vein anastomoses are viable options for breast reconstruction with PAP flap. The utilization of either one or two veins did not significantly affect ischemia time or flap loss. Fat necrosis exhibited a higher incidence in the single-vein group; however, this difference was also not statistically significant. These findings underscore the effectiveness of both approaches, providing surgeons with flexibility in tailoring their surgical techniques based on patient-specific considerations and anatomical factors.

Analyzing mastectomy and reconstruction weight in immediate autologous breast reconstruction: A preliminary study.

This study aims to explore the ideal breast size by assessing the relationship between mastectomy to free flap weight ratio and complications as well as patient-reported outcomes in autologous breast reconstruction (ABR). A retrospective review of patients undergoing bilateral immediate ABR with mastectomy and flap weights available was completed. Patients were divided into three groups based on the ratio of mastectomy to flap weights. The patients were grouped as "maintained" if the flap weight was within 10% of the mastectomy weight. Patients with a weight difference greater than 10% were used to declare "downsized" or "upsized." Outcomes included complications and four domains of the BREAST-Q at 1-year postoperatively. Three hundred and fifty-ninepatients were included in the analysis, of which 112 were downsized, 91 maintained, and 156 upsized, respectively. Presence of complications did not significantly differ among the groups. At 1-year postoperatively, Sexual Well-being significantly differed (p = 0.033). Between preoperative and 1 year, patients who upsized experienced an improvement in Satisfaction with Breasts by 16 points (p < 0.001), while patients who downsized experienced a decline in Physical Well-being of the Chest by 7 points (p = 0.016). Multivariable linear regression model showed that Sexual Well-being was 13 points lower in the downsized cohort than in the maintained cohort (β = -13, 95% confidence interval: -21to -5.4; p = 0.001). Although complication rates do not significantly differ between the three cohorts, patients who downsize may have lower Sexual Well-being postoperatively. Surgeons should consider our preliminary findings to counsel patients preoperatively about the predicted breast size and the impact of downsizing on sexual health.

Impact of post-operative infection on revision procedures in breast reconstruction: A marketscan database analysis

BackgroundEsthetic complications, such as capsular contracture and soft-tissue contour defects, hinder the desired outcomes of breast reconstruction. As subclinical infection is a prevailing theory behind capsular contracture, we investigated the effects of post-operative infections on these issues and revision procedures. MethodsWe conducted a retrospective database study (2007–2021) on breast reconstruction patients from the MarketScan® Databases. Esthetic complications were defined by their associated revision procedures and queried via CPT codes. Severe capsular contracture (Grade 3–4) was defined as requiring capsulotomy or capsulectomy with implant removal or replacement. Moderate and severe soft-tissue defects were determined by the need for fat grafting or breast revision, respectively. Generalized linear models were used, adjusting for comorbidities and surgical factors (p < 0.05). ResultsWe analyzed the data on 62,510 eligible patients. Post-operative infections increased the odds of capsulotomy (OR 1.59, p < 0.001) and capsulectomy (OR 2.30, p < 0.001). They also raised the odds of breast revision for severe soft-tissue defects (OR 1.21, p < 0.001). There was no significant association between infections and fat grafting for moderate defects. Patients who had post-operative infections were also more likely to experience another infection after fat grafting (OR 3.39, p = 0.0018). In two-stage reconstruction, infection after tissue expander placement was associated with greater odds of infection after implant placement. ConclusionPost-operative infections increase the likelihood of developing severe soft-tissue defects and capsular contracture requiring surgical revision. Our data reinforce the role of infections in the pathophysiology of capsular contracture. Additionally, infections elevate the risk of subsequent infections after fat grafting for moderate defects, further increasing patient morbidity.

Balancing Innovation and Patient Care in Breast Cancer: Integrating Hypofractionated Proton Therapy With Breast Reconstruction Outcomes.

This review aims to assess the application of hypofractionated proton therapy in breast cancer reconstruction, analyzing its advantages, challenges, and broader implications for patient care. The goal is to comprehensively understand how this innovative approach can be integrated into breast cancer treatment. Proton therapy exhibits superior target coverage and safety, reducing radiation-induced complications and sparing critical organs, but skin toxicity outcomes differ from photon therapy. Tissue expanders are vital in breast reconstruction, employing innovative planning for positive long-term outcomes and highlighting the importance of balancing cancer treatment effectiveness with cosmetic outcomes. Hypofractionated proton therapy and breast cancer reconstruction present promising innovations with notable advantages in target coverage and organ sparing. However, variations in skin toxicity outcomes and the need for a careful balance between treatment effectiveness and cosmetic outcomes underscore ongoing challenges. Future directions should focus on refining treatment protocols, optimizing patient selection criteria, and integrating emerging technologies to enhance therapeutic outcomes while minimizing adverse effects.

The Impact of Radiation on Nipple Symmetry After Bilateral Nipple-Sparing Mastectomy and Implant-Based Reconstruction: An Objective Analysis.

Radiation therapy can adversely affect outcomes of implant-based breast reconstruction, potentially complicating procedures like nipple-sparing mastectomy (NSM), which is increasingly popular in breast cancer management. This study aims to evaluate the impact of radiation on nipple symmetry in patients undergoing bilateral NSM with implant-based reconstruction. We conducted a retrospective analysis using data from an Emory University review board-approved database. This encompassed bilateral NSMs coupled with immediate implant-based reconstructions. The BCCT.core software was employed to objectively measure nipple asymmetry preoperatively and postoperatively. Metrics, such as Breast Retraction Assessment values, upper nipple retraction, lower breast contour, and nipple to midline (NML) discrepancies were quantified. The study included 80 patients with a minimum of 1 year of follow-up; among them, 15 received radiation therapy (RT) while 65 did not. The reconstructions were divided into tissue expander, used in 39 cases (48.8%), and direct-to-implant (DTI), employed in 41 cases (51.2%). The DTIs were further categorized based on the location of the implant: 22 subpectoral and 19 prepectoral. Radiation was applied to 15 breasts, distributed among prepectoral DTI (4), subpectoral DTI (6), and tissue expander (5). Breast Retraction Assessment scores significantly differed between the nonirradiated and irradiated groups (1.49 vs 2.64, P < 0.0004). Nipple to midline differences and Upper Nipple Retraction also significantly varied postradiation, especially when comparing subpectoral and prepectoral implant placements. Radiation therapy has a detrimental effect on nipple symmetry after bilateral NSM and implant-based reconstruction, with variations seen regardless of the implant's placement or the reconstructive technique utilized. Specifically, subpectoral reconstructions irradiated were prone to lateral nipple displacement, likely related to radiation-induced pectoralis muscle changes, while prepectoral irradiated reconstructions tended to have increased vertical displacement. These insights are crucial for patient education and surgical planning in the context of radiation and breast reconstruction.

Optimizing Aesthetic Outcomes in Autologous Breast Reconstruction: 20 Pearls for Practice.

Autologous breast reconstruction with a deep inferior epigastric artery perforator (DIEP) flap is an excellent option for many patients proceeding with mastectomy for surgical management of their breast cancer. As microsurgical techniques and results improve and ensure consistent flap survival, optimizing aesthetic outcomes may become a primary focus. This article outlines 20 tips that can improve aesthetic results in DIEP flap breast reconstruction, based on our senior author's 8-year career in microsurgical breast reconstruction, with an emphasis on enhanced cosmesis. We highlight tips on preoperative planning, intraoperative, and revision stages of the reconstruction and provide a schematic for integrating the tips into a reader's microsurgical breast reconstruction practice.

The Impact of Marijuana Use on Postoperative Outcomes in Abdominal-based Free Flap Breast Reconstruction.

There is an increasing prevalence of marijuana use in the general population yet clinical studies on marijuana's effect on surgical outcomes remain limited. Marijuana's effect on wound healing, venous thromboembolism (VTE) due to endothelial inflammation, and bleeding due to inhibited platelet function have been cited based on animal models but have not been evaluated clinically in patients undergoing microsurgical reconstruction. Retrospective chart review was performed on all patients who underwent abdominal-based free flap breast reconstruction in a single institute from August 2018 to December 2022. Patient self-reported marijuana use, demographics, total narcotic use during hospitalization converted to oral morphine milligram equivalent (MME), and 90-day complications were collected and compared. A total of 162 patients were included and 13 patients (8.5%) had reported marijuana use on presurgical history. Marijuana users are more likely to be younger and report concurrent nicotine smoking. Marijuana users were also at a significantly elevated risk of developing symptomatic VTE (15 vs. 1%; odds ratio (OR) 13.4 [95% confidence interval (CI) 1.71-104.2]; p = 0.01) and marijuana use remained a significant risk factor with multivariate analysis. On postoperative 90-day complications, there was no increased risk of flap loss, reoperation, postoperative transfusion, or hematoma associated with marijuana use, and no significantly increased risk for overall donor or recipient site complications. Marijuana users required significantly more narcotics for pain control during hospitalization (100 ± 77 vs. 49 ± 45 MME; p = 0.0003), although they had similar lengths of stay, achievement of mobilization on post operative day (POD)1, and maximal pain scores. Marijuana use increases the risks of postoperative VTE and increased postoperative narcotic requirements in patients who underwent abdominal-based free flap breast reconstruction. Future prospective cohort study is required to further understand marijuana-associated risks in microsurgical procedures.

The Oncological and Surgical Outcomes of Immediate Oncoplastic Breast Reconstruction With Contralateral Breast Adjustment.

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

In hospital outcomes of autologous and implant-based breast reconstruction in patients with chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is a common comorbid condition that can be associated with postoperative mortality and morbidity. However, the outcome profile of patients with COPD after breast reconstruction has yet to be established. Therefore, this study aimed to assess the postoperative outcomes in patients with COPD who underwent autologous (ABR) and implant-based breast reconstruction (IBR). National Inpatient Sample was used to identify patients who underwent ABR or IBR from Q4 2015 to 2020. Multivariable logistic regressions were used to compare inhospital outcomes between COPD and non-COPD patients while adjusting for demographics, primary payer status, hospital characteristics, and comorbidities. There were 1288 (9.92%) COPD and 11,696 non-COPD patients who underwent ABR. Meanwhile, 1742 (9.70%) COPD and 16,221 non-COPD patients underwent IBR. In both ABR and IBR, patients with COPD had higher rates of seroma (ABR, aOR=1.863, 95% CI=1.022-3.397, and p=0.04; IBR, aOR=1.524, 95% CI=1.014-2.291, and p=0.04), infection (ABR, aOR=1.863, 95% CI=1.022-3.397, andp=0.04; IBR, aOR=1.956, 95% CI=1.205-3.176, and p=0.01), and prolonged LOS (p<0.01). Specifically, patients with COPD in ABR had higher risks of respiratory complications (aOR=1.991, 95% CI=1.291-3.071, and p<0.01) and incurred higher total hospital charges (p<0.01). Meanwhile, patients with COPD undergoing IBR had elevated risks of renal complications (aOR=3.421, 95% CI=2.108-5.55, and p<0.01), deep wound complications (aOR=3.191, 95% CI=1.423-7.153, and p<0.01), and a higher rate of transfers out (aOR=1.815, 95% CI=1.081-3.05, and p=0.02). COPD is an independent risk factor associated with distinct adverse outcomes in ABR and IBR. These findings can be valuable for preoperative risk stratification, determining surgical candidacy, and planning postoperative management in patients with COPD.
