Nipple-sparing mastectomy and immediate breast reconstruction by prepectoral implant for the management of giant phyllodes tumors: A case series.

Phyllodes tumor is an uncommon breast neoplasm that is present in variable sizes. Giant phyllodes are those larger than 10 cm in diameter. Clinically, giant phyllodes tumors present as a visible, rapidly growing mass distorting the breast contour. Such tumors with large size and rapid growth rate suggest a phyllode diagnosis of fibroadenoma. Planning a standard treatment strategy for these tumors is quite challenging. While adequate surgical excision with tumor-free resection margins is the standard of care for most giant phyllodes cases, borderline and malignant giant phyllodes tumors might require wider resections given their high recurrence rates. Some authors described total mastectomy as the treatment option for giant borderline and malignant phyllodes to obtain wide, clear margins. Between March 2022 and September 2023, our surgical oncology department presented and operated on three cases of giant phyllodes. They underwent a nipple-sparing mastectomy and immediate breast reconstruction using pre-pectoral silicone implants. We think that with such a procedure, we can benefit from the wide, safe margins of mastectomy that have been proven to decrease local recurrence rates while considering the aesthetic outcome.

Chatting Up the Next Big Thing: Generating Novel Ideas for Systematic Reviews in Breast Reconstruction Research Using Chat-GPT.

BACKGROUND: In reconstructive plastic surgery, the need for comprehensive research and systematic reviews is apparent due to the field's intricacies, influencing the evidence supporting specific procedures. Although Chat-GPT's knowledge is limited to September 2021, its integration into research proves valuable for efficiently identifying knowledge gaps. Therefore, this tool becomes a potent asset, directing researchers to focus on conducting systematic reviews where they are most necessary. METHODS: Chat-GPT 3.5 was prompted to generate 10 unpublished, innovative research topics on breast reconstruction surgery, followed by 10 additional subtopics. Results were filtered for systematic reviews in PubMed, and novel ideas were identified. To evaluate Chat-GPT's power in generating improved responses, two additional searches were conducted using search terms generated by Chat-GPT. RESULTS: Chat-GPT produced 83 novel ideas, leading to an accuracy rate of 83%. There was a wide range of novel ideas produced among topics such as transgender women, generating 10 ideas, whereas acellular dermal matrix (ADM) generated five ideas. Chat-GPT increased the total number of manuscripts generated by a factor of 2.3, 3.9, and 4.0 in the first, second, and third trials, respectively. While the search results were accurate to our manual searches (95.2% accuracy), the greater number of manuscripts potentially diluted the quality of articles, resulting in fewer novel systematic review ideas. CONCLUSION: Chat-GPT proves valuable in identifying gaps in the literature and offering insights into areas lacking research in breast reconstruction surgery. While it displays high sensitivity, refining its specificity is imperative. Prudent practice involves evaluating accomplished work and conducting a comprehensive review of all components involved.

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

PURPOSE: Implant-based breast reconstruction (IBR) is being increasingly performed with implant placed above the pectoral muscle (pre-pectoral), instead of below the pectoral muscle (sub-pectoral). Currently, there is a lack of comparative data on clinical and patient-perceived outcomes between pre- vs. sub-pectoral IBR. We investigated whether this difference in surgical approach influenced clinical or patient-perceived outcomes. METHODS: This prospective non-randomised longitudinal cohort study (ClinicalTrials.gov identifier: NCT04842240) recruited patients undergoing immediate IBR at the Leeds Breast Unit (Sep 2019-Sep 2021). Data collection included patient characteristics and post-operative complications. Patient-Reported Outcome Measures were collected using the BREAST-Q questionnaire at baseline, 2 weeks, 3- and 12-months post-surgery. RESULTS: Seventy-eight patients underwent IBR (46 patients pre-pectoral; 59% vs. 32 patients sub-pectoral; 41%). Similar complication rates were observed (15.2% pre-pectoral vs. 9.4% sub-pectoral; p = 0.44). Overall implant loss rate was 3.8% (6.5% pre-pectoral vs. 0% sub-pectoral; p = 0.13). Respective median Breast-Q scores for pre- and sub-pectoral IBR at 3 months were: breast satisfaction (58 vs. 48; p = 0.01), psychosocial well-being (60 vs. 57; p = 0.9), physical well-being (68 vs. 76; p = 0.53), and Animation Q scores (73 vs. 76; p = 0.45). Respective Breast-Q scores at 12 months were: breast satisfaction (58 vs. 53; p = 0.3), psychosocial well-being (59 vs. 60; p = 0.9), physical well-being (68 vs. 78; p = 0.18), and Animation Q scores (69 vs. 73; p = 0.4). CONCLUSIONS: This study demonstrates equivalent clinical and patient-perceived outcomes between pre- and sub-pectoral IBR. The study findings can be utilised to aid informed decision making regarding either surgical option.

Tissue perfusion in DIEP flaps using Indocyanine Green Fluorescence Angiography, Hyperspectral imaging, and Thermal imaging.

Flap necrosis continues to occur in skin free flap autologous breast reconstruction. Therefore, we investigated the benefits of indocyanine green angiography (ICGA) using quantitative parameters for the objective, perioperative evaluation of flap perfusion. In addition, we investigated the feasibility of hyperspectral (HSI) and thermal imaging (TI) for postoperative flap monitoring. A single-center, prospective observational study was performed on 15 patients who underwent deep inferior epigastric perforator (DIEP) flap breast reconstruction (n=21). DIEP-flap perfusion was evaluated using ICGA, HSI, and TI using a standardized imaging protocol. The ICGA perfusion curves and derived parameters, HSI extracted oxyhemoglobin (oxyHb) and deoxyhemoglobin (deoxyHb) values, and flap temperatures from TI were analyzed and correlated to the clinical outcomes. Post-hoc quantitative analysis of intraoperatively collected data of ICGA application accurately distinguished between adequately and insufficiently perfused DIEP flaps. ICG perfusion curves identified the lack of arterial inflow (n=2) and occlusion of the venous outflow (n=1). In addition, a postoperatively detected partial flap epidermolysis could have been predicted based on intraoperative quantitative ICGA data. During postoperative monitoring, HSI was used to identify impaired perfusion areas within the DIEP flap based on deoxyHb levels. The results of this study showed a limited added value of TI. Quantitative, post-hoc analysis of ICGA data produced objective and reproducible parameters that enabled the intraoperative detection of arterial and venous congested DIEP flaps. HSI appeared to be a promising technique for postoperative flap perfusion assessment. A diagnostic accuracy study is needed to investigate ICGA and HSI parameters in real-time and demonstrate their clinical benefit.

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.

Postoperative outcomes of minimally invasive versus conventional nipple-sparing mastectomy with prosthesis breast reconstruction in breast cancer: a meta-analysis.

Breast cancer is the most common malignant tumor worldwide, and mastectomy remains the primary strategy for treating early stage breast cancer. However, the complication rates, surgical variables, and oncologic safety of minimally invasive nipple-sparing mastectomy (MINSM) have not been fully addressed. We systematically searched PubMed, Web of Science, Embase, and the Cochrane Library for randomized-controlled trials (RCTs) and non-RCTs that compared MINSM with conventional nipple-sparing mastectomy (CNSM), both followed by Prosthesis Breast Reconstruction (PBR). The main outcomes observed included overall complications, (Grade III) complications, skin and nipple necrosis, wound dehiscence, infection, seroma, hematoma, implant loss, and oncologic safety (positive margins and recurrence). Secondary outcomes included operation time, blood loss, hospital stay, cost-effectiveness, and patient satisfaction. Binary and continuous variables were compared using odds ratios (OR) and mean differences (MD) with 95% confidence intervals (CI). A total of 10 studies involving 2,166 patients were included. There were no statistically significant differences between MINSM and CNSM in terms of skin necrosis, wound dehiscence, infection, seroma, hematoma, implant loss, or oncologic safety. However, MINSM significantly reduced overall complications (OR = 0. 74, 95% CI [0. 58, 0. 94], p = 0. 01) and (Grade III) complications (OR = 0. 47, 95% CI [0. 31, 0. 71], p = 0. 0003). Nipple necrosis events were also significantly reduced in the MINSM group (OR = 0. 49, 95% CI [0. 30, 0. 80], p = 0. 005). Patient satisfaction improved notably in the MINSM group. Additionally, compared with the CNSM group, the MINSM group had longer operating times (MD = 46. 88, 95% CI [19. 55, 74. 21], p = 0. 0008) and hospital stays (MD = 1. 39, 95% CI [0. 65, 2. 12], p < 0. 001), while intraoperative blood loss was significantly reduced (MD = -29. 05, 95% CI [-36. 20, -21. 90], p < 0. 001). Compared with CNSM, MINSM offers advantages in reducing complications and intraoperative blood loss, as well as improving aesthetic outcomes and patient satisfaction. Therefore, MINSM may become a viable option for breast surgery. Nevertheless, a long-term evaluation of the oncologic safety of this approach is necessary to ensure its efficacy and safety for patients.

Effectiveness of extended antibiotic prophylaxis in implant-based breast reconstruction surgery: A meta-analysis.

INTRODUCTION: Considerable research has been carried out on the postoperative benefits of extended antibiotic prophylaxis (EAP) in different surgical contexts, generating various results regarding its effectiveness. Some studies indicate positive outcomes, whereas others indicate no significant advantages. Our approach involves conducting a comprehensive systematic review and meta-analysis to provide a more nuanced understanding of the role of extended antibiotic use because of the lack of a consistent consensus. METHODS: A thorough search of the Cochrane Library, Embase, and MEDLINE electronic databases was conducted to identify relevant studies. The metafor package in R software was used for meta-analysis. We collected risk ratios (RRs) for surgical site infection (SSI) in the EAP versus non-EAP groups from the included studies to assess the effects of EAP on reducing the risk of SSI. The meta-analysis used a random-effects model, and effect sizes were presented with their corresponding 95% confidence intervals (CIs). RESULTS: Fourteen studies, involving 12,572 patients who underwent implant-based reconstruction postmastectomy, were included. Pooling the results of the studies that used EAP until drain removal revealed no protective effect of EAP against SSI risk (RR = 0.84; 95% CI: 0.60-1.18). Similarly, our analysis revealed no significant benefit of EAP in studies where EAP was not contingent on drain removal (RR = 0.70; 95% CI: 0.46-1.07). CONCLUSIONS: EAP administration did not decrease the incidence of SSI in individuals undergoing implant-based breast reconstruction surgery postmastectomy.

Unforeseen Complications of Pembrolizumab in Breast Reconstruction Post-Mastectomy.

A 53-year-old post-menopausal Indian female presented with invasive ductal carcinoma, treated with neoadjuvant chemotherapy and pembrolizumab due to a PD-L1 combined positive score of 5. Following a right mastectomy and axillary dissection, she received a breast expander and AlloDerm™ graft. After resuming pembrolizumab and paclitaxel postoperatively, she developed severe breast redness and high-grade fever, necessitating expander removal due to suspected pembrolizumab-induced complications. This case underscores the unique and severe adverse effects of pembrolizumab on breast reconstruction, highlighting the need for careful monitoring and management in patients undergoing similar treatments. LEARNING POINTS: Among patients with early triple-negative breast cancer, the combination of pembrolizumab with neoadjuvant chemotherapy enhances outcomes compared to chemotherapy alone.Early recognition is essential for managing pembrolizumab-induced complications, as demonstrated by the need for expander removal and debridement in this case.The unique adverse effects observed in this case underscore the importance of tailoring cancer treatment plans to individual patients, taking into account the potential risks associated with immunotherapy in the context of reconstructive surgery.

The effect of a local anesthetic cocktail in a serratus anterior plane and PECS 1 block for implant-based breast reconstruction.

Introduction: Enhanced recovery after surgery (ERAS) protocols have been implemented to decrease opioid use and decrease patient hospital length of stay (LOS, days). Serratus anterior plane (SAP) blocks anesthetize the T2 through T9 dermatomes of the breast and can be applied intraoperatively. The purpose of this study was to compare postoperative opioid (OME) consumption and LOS between a control group, an ERAS group, and an ERAS/local anesthetic cocktail group in patients who underwent implant-based breast reconstruction. Methods: In this study, 142 women who underwent implant-based breast reconstruction between 2004 and 2020 were divided into Group A (46 patients), a historical cohort; Group B (73 patients), an ERAS/no-block control group; and Group C (23 patients), an ERAS/anesthetic cocktail study group. Primary outcomes of interest were postanesthesia care unit (PACU), inpatient and total hospital OME consumption, and PACU LOS. Results: A significant decrease was observed from Group A to C in PACU LOS (103.3 vs. 80.2 vs. 70.5; p = 0.011), OME use (25.1 vs. 11.4 vs. 5.7; p < 0.0001), and total hospital OME (120.3 vs. 95.2 vs. 35.9; p < 0.05). No difference was observed in inpatient OMEs between the three groups (95.2 vs. 83.8 vs. 30.8; p = 0.212). Despite not reaching statistical significance, Group C consumed an average of 50-60 % less opioids per patient than did Group B in PACU, inpatient, and total hospital OMEs. Conclusion: Local anesthetic blocks are important components of ERAS protocols. Our results demonstrate that a combination regional block with a local anesthetic cocktail in an ERAS protocol can decrease opioid consumption in implant-based breast reconstruction.

Automatic segmentation of MRI in prospective breast volume evaluation: Comparison of different assessments for immediate breast reconstruction.

BACKGROUND: Assessment of breast volume is essential in preoperative planning of immediate breast reconstruction (IBR) surgery to achieve satisfactory cosmetic outcome. This study introduced a breast volume measurement tool that can be used to perform automatic segmentation of magnetic resonance images (MRI) and calculation of breast volume. We compared the accuracy and reliability of this measurement method with four other conventional modalities. METHODS: Patients who were scheduled to undergo mastectomy with IBR between 2016 and 2021 were enrolled in the study. Five different breast volume assessments, including automatic segmentation of MRI, manual segmentation of MRI, 3D surface imaging, mammography, and the BREAST-V formula, were used to evaluate different breast volumes. The results were validated using water displacement volumes of the mastectomy specimens. RESULTS: In this pilot study, a total of 50 female patients met the inclusion criteria and contributed 54 breast specimens to the volumetric analysis. There was a strong linear association between the MRI and water displacement methods (automatic segmentation: r = 0.911, p < 0.001; manual segmentation: r = 0.924, p < 0.001), followed by 3D surface imaging (r = 0.858, p < 0.001), mammography (r = 0.841, p < 0.001), and Breast-V formula (r = 0.838, p < 0.001). Breast volumes measured using automatic and manual segmentation of MRI had lower mean relative errors (30.3% ± 22.0% and 28.9% ± 19.8, respectively) than 3D surface imaging (38.9% ± 31.2), Breast-V formula (44.8% ± 25.8), and mammography (60.3% ± 37.6). CONCLUSION: Breast volume assessment using the MRI methods had better accuracy and reliability than the other methods used in our study. Breast volume measurement using automatic segmentation of MRI could be more efficient compared to the conventional methods.

Comparison of Nefopam-Based Patient-Controlled Analgesia with Opioid-Based Patient-Controlled Analgesia for Postoperative Pain Management in Immediate Breast Reconstruction Surgery: A Randomized Controlled Trial.

Background/Objectives: Immediate breast reconstruction surgery (BRS) often leads to significant postoperative pain, necessitating effective analgesia. This study aimed to compare the analgesic efficacy of patient-controlled analgesia (PCA) containing nefopam with that of PCA containing opioids alone in patients undergoing BRS. Methods: A prospective, double-blind, randomized controlled trial was conducted on 120 patients undergoing immediate BRS after mastectomy. Patients were randomly allocated to receive PCA with fentanyl alone (Group F: fentanyl 10 mcg/kg), fentanyl and nefopam (Group FN: fentanyl 5 mcg/kg + nefopam 1 mg/kg), or nefopam alone (Group N: nefopam 2 mg/kg). Pain intensity (expressed in VASr and VASm), opioid consumption, and opioid-related complications were assessed. Results: PCA with nefopam, either alone or in combination with opioids, demonstrated non-inferior analgesic efficacy compared to PCA with fentanyl alone. At 24 h postoperatively, the VASr scores were 2.9 ± 1.0 in Group F, 3.1 ± 1.2 in Group FN, and 2.8 ± 0.9 in Group N (p = 0.501). At the same timepoint, the VASm scores were 4.1 ± 1.2 in Group F, 4.5 ± 1.5 in Group FN, and 3.8 ± 1.4 in Group N (p = 0.129). Significant differences among the three groups were observed at all timepoints except for PACU in terms of the total opioid consumption (p < 0.0001). However, there were no significant differences in opioid-related complications among the three groups. Conclusions: PCA with nefopam, whether alone or in combination with opioids, offers non-inferior analgesic efficacy compared to PCA with fentanyl alone in patients undergoing immediate BRS.

Shifting toward total drainless approach in DIEP flap-based breast reconstruction: Evaluation of safety.

With increasing interest in swift postoperative recovery, there has been a trend toward omitting drains in deep inferior epigastric perforator (DIEP) flap-based breast reconstruction, ideally aiming to avoid drains in the breasts and abdomen. This study evaluated our transition toward total drainless reconstruction, focusing specifically on the safety of omitting drains in the breasts. Patients who underwent breast reconstruction with DIEP flap from 2018 to 2023 were reviewed. They were divided into 3 groups: group A (with drains in the abdomen and breast), group B (drains only in the breast), and group C (total drainless). For group C, routine ultrasound examinations were performed to check for fluid accumulation. Complication profiles were compared among the groups. In total, 294 cases were included, comprising 77 in group A, 112 in group B, and 105 in group C. Chronologically, a gradual increase in the proportion of cases in group C was observed, with the complication rates remaining stable. On comparing the complication profiles of the recipient and donor sites among the 3 groups, no significant differences were found. Breast seroma, persisting 1 month postoperatively, was exclusively detected in 6 (5.7%) cases within group C, all of whom were treated with outpatient clinic-based aspiration. When restricting the analysis to group C, a greater weight of mastectomy specimen and axillary lymph node dissections exhibited an independent association with breast seroma development. Smooth transition to total drainless DIEP breast reconstruction appears safe, without significantly increasing the risks of complication.

Surgical and Patient-Reported Outcomes After Mastectomy and Implant-Based Prepectoral Reconstruction Using TIGR® Synthetic Mesh.

Background Single-stage direct-to-implant (DTI) breast reconstruction after mastectomy has gained popularity over the last decade, thanks to the wide use of biological matrices and synthetic meshes. Despite their high cost, there is no evidence of superior outcome from the biological matrices compared to the synthetic meshes. In this study, we aimed to evaluate our experience with TIGR, a synthetic, long-term absorbable mesh, in mastectomy and immediate breast reconstruction (MIBR) with a focus on patient-reported outcomes (PROMs). Methods This was a single-trust prospective quality improvement study conducted between 2017 and 2019. The main objectives were complication rates including infection, implant loss, and other surgical complications in patients undergoing TIGR mesh-assisted MIBR in the prepectoral plane for either cancer or risk reduction. PROMs were measured using the validated European Organisation for Research and Treatment of Cancer (EORTC) breast questionnaire module. Clinical evaluations were conducted at one week, three weeks, and 12 months postoperatively. All patients provided written consent, and the audit was registered with the Quality Improvement Department of the organization. Results One hundred and twelve meshes were used in 93 patients with a mean age of 49 (24-75) years and a body mass index (BMI) of 23.4 (19.1-29.6). During the follow-up period, complications occurred in 26 patients (28%), including infection in four (4.3%), complete skin flap necrosis in one (1%), partial flap necrosis in three (3.2%), and implant loss in four (4.3%) patients. PROM data from 41 individuals indicated a moderate overall quality of life (82.7%), with high functional domain scores with relatively lower emotional functioning scores. Symptom domains generally scored poorly except for body image and sexual functioning. Conclusion Mastectomy and immediate prepectoral breast reconstruction using TIGR mesh is safe with low major complication rates. It is associated with high functional and quality of life scores but low scores in symptom domains which could be multifactorial. However, limitations due to study type and follow-up duration suggest caution in generalizing findings.

National trends in revision procedures in post-mastectomy breast reconstruction: Autologous vs implant-based approaches.

BACKGROUND: Breast reconstruction involves collaborative decision-making between patients and surgeons, but the need for multiple revisions after the initial reconstructive surgery process can burden patients and the healthcare system. This study explored how the type of breast reconstruction (autologous [ABR], immediate implant-based reconstruction [IBR], or two-stage IBR) impacts postreconstruction revision rates. METHOD: Using MarketScan Databases, a retrospective database study (2007-2021) was conducted, identifying revision procedures through Current Procedural Terminology codes. Statistical analysis with linear models, adjusted for patient characteristics and surgical factors, used a significance threshold of p < 0.05. RESULTS: Among 58,264 patients, 6.2% of ABR patients, 3.8% of immediate IBR patients, and 3.6% of two-stage IBR patients underwent future revisions. IBR had a 51% lower incidence rate of revision operations than ABR (incidence rate ratio = 0.49, p < 0.001). Within IBR, there was no significant difference in the number of operations between immediate IBR (0.06 ± 0.32) and two-stage IBR (0.05 ± 0.32, p = 0.95). Immediate IBR demonstrated 12% (OR = 0.88, p = 0.0022) and 70% (OR = 0.30, p < 0.001) lower odds of requiring breast revision and fat grafting compared to ABR, respectively. Two-stage reconstruction had 66 % lower odds of requiring only fat grafting than ABR (OR = 0.34, p < 0.001). CONCLUSION: ABR necessitated a higher number of total revision procedures after completion of the initial reconstruction. These findings will better equip providers and patients to counsel patients in understanding their reconstructive journey, planning their reconstructions and timing, and provide more accurate estimates of the number of procedures that will be required to reach their aesthetic goals and final outcome.

Surgical delay in abdominal based flap surgery: a scoping review.

Background: The abdominal donor site is the most common flap used for breast reconstruction, with flap necrosis a feared complication. The technique of surgical 'delay' involves the inducing of relative ischemia to promote neovascularisation, amongst other metabolic adaptations, and has been used to augment flap vascularity and reduce this complication. There is significant variability in the manner in which flap surgery and surgical delay may be performed, such as the vessels ligated, the presence and degree of flap elevation, and the decision to harvest muscle with the flap, amongst other factors. A formal review of techniques, however, has not yet been performed, and there is no consensus as to the optimal technique for surgical delay. Methods: A scoping review of the current literature was undertaken to determine the optimal surgical delay technique in abdominal-based flap surgery. A literature search was conducted across PubMed, Embase, Cochrane, and Medline databases. Data regarding the type of flap surgery, delay techniques, and corresponding clinical outcomes was collected and categorised by technique type. Results: Nine studies met the inclusion criteria and were included for review. Levels of evidence and rates of complications were compared. The range of surgical delay techniques reported in the literature was described. Surgical delay was found to reduce overall complication rates, and the available data suggests it may be particularly beneficial in high-risk patients. Conclusions: The current data support delay as a viable method for reducing rates of complications. Further studies and data are required to compare surgical delay techniques and determine the benefit delay may pose to patients with risk factors.

Management of skin necrosis and wound dehiscence following brown recluse spider bite in the course of breast reconstruction: A case report.

Background: Breast reconstruction following mastectomy is a critical component of breast cancer treatment, aimed at improving patient quality of life. However, the management is fraught with potential complications, including skin necrosis and wound dehiscence, which can significantly impact clinical outcomes. Case Presentation: We report a unique case of a patient, 5 years post-breast reconstruction following mastectomy and radiation therapy, who developed severe skin necrosis and wound dehiscence due to a brown recluse spider bite on the reconstructed breast. The complication necessitated the debridement of skin, removal of the implant, and further reconstruction with a latissimus flap. Discussion: The case underscores the unusual etiology of spider bite-induced necrosis in breast reconstruction and highlights the challenges and strategic considerations in managing such complications. Upon presentation, the patient's affected breast area showed signs of extensive necrosis and wound dehiscence, directly attributed to the cytotoxic effects of the brown recluse spider's venom. The venom's pathophysiology involves a complex cascade, leading to local and systemic effects. The local effects, marked by dermonecrosis, com- promised skin integrity in this instance. Systemic effects, not observed in this patient but potentially severe, can include hemolysis, coagulopathy, and acute renal failure, highlighting the seriousness of brown recluse spider bites. Conclusion: In conclusion, this case illustrates the complexities of managing breast reconstruction post-mastectomy complications, particularly those caused by external factors such as brown recluse spider bites. It highlights the need for meticulous attention to unusual etiologies of necrosis and dehiscence, demonstrating the importance of adaptable surgical strategies and a thorough understanding of venom pathophysiology in ensuring successful patient outcomes.

Locally advanced breast cancer patients should be cautious about the immediate breast reconstruction after mastectomy: a pooling analysis of safety and efficacy.

BACKGROUND: The purpose of this study was to compare safety and efficacy outcomes between immediate breast reconstruction (IBR) and mastectomy alone in locally advanced breast cancer patients. METHODS: We conducted a comprehensive literature search of PUBMED, EMBASE, and Cochrane databases. The primary outcomes evaluated were overall survival, disease-free survival, and local recurrence. The secondary outcome was the incidence of surgical complications. All data were analyzed using Review Manager 5.3. RESULTS: Sixteen studies, involving 15,364 participants were included in this meta-analysis. Pooled data demonstrated that patients underwent IBR were more likely to experience surgical complications than those underwent mastectomy alone (HR: 3.96, 95%CI [1.07,14.67], p = 0.04). No significant difference was found in overall survival (HR: 0.94, 95%CI [0.73,1.20], p = 0.62), disease-free survival (HR: 1.03, 95%CI [0.83,1.27], p = 0.81), or breast cancer specific survival (HR: 0.93, 95%CI [0.71,1.21], p = 0.57) between IBR group and Non-IBR group. CONCLUSIONS: Our study demonstrates that IBR after mastectomy does not affect the overall survival and disease-free survival of locally advanced breast cancer patients. However, IBR brings with it a nonnegligible higher risk of complications and needs to be fully evaluated and carefully decided.

Quality of Life after Mastectomy with or without Breast Reconstruction and Breast-Conserving Surgery in Breast Cancer Survivors: A Cross-Sectional Study at a Tertiary Hospital in Ghana.

(1) Background: Breast cancer is the leading malignancy worldwide, and in Ghana, it has a poor overall survival rate. However, approximately 50% of cases are cases of early-stage disease, and with advances in breast cancer treatment and improvements in survival, quality of life (QOL) is becoming as important as the treatment of the disease. (2) Methodology: This was a cross-sectional study of survivors who had breast-conserving surgery (BCS), mastectomy only (M) and mastectomy with breast reconstruction (BRS) from 2016 to 2020 at a tertiary hospital in Ghana, comparatively assessing their QOL using EORTC QLQ C-30 and EORTC QLQ BR-23. (3) Results: The study participants had an overall global health status (GHS) median score of 83.3 [IQR: 66.7-91.7] with no significant differences between the surgery types. The BRS group had statistically significant lower median scores for the functional scale (82.8 and 51.0) and the highest scores for the symptomatic scale (15.7 and 16.5). Body image was significantly lowest for the BRS group (83.3) [68.8-91.7] and highest (100) [91.7-100] for the BCS group (p < 0.001). (4) Conclusion: There is a need to develop support systems tailored at improving the QOL of breast cancer survivors taking into consideration the type of surgery performed.

African Americans have worse in-hospital outcomes in autologous and implant-based breast reconstruction: a population-based study from the National Inpatient Sample from 2015 to 2020.

African Americans have a long history of disparities in healthcare. However, whether their racial disparity exists in breast reconstruction outcomes is less clear. This study compared short-term outcomes of African Americans and Caucasians who underwent autologous (ABR) and implant-based breast reconstruction (IBR). Patients having ABR or IBR were identified in the National Inpatient Sample from Q4 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between African Americans and Caucasians, adjusted for demographics, socioeconomic status, comorbidities, and hospital characteristics. In ABR, there were 8296 (63.89%) Caucasians and 1809 (13.93%) African Americans. In IBR, there were 12,258 (68.24%) Caucasians and 1847 (10.28%) African Americans. During the same period, 32,406 (64.87%) Caucasians and 7702 (15.42%) African Americans underwent mastectomy, indicating a lower reconstruction rate in African Americans, particularly in IBR. African Americans presented with significant preoperative differences, including younger age, higher comorbid burden, and pronounced socioeconomic disadvantages. After accounting for preoperative differences, in ABR, African Americans had higher renal complications (aOR = 1.575, 95 CI = 1.024-2.423, p = 0.04) hemorrhage/hematoma (aOR = 1.355, 95 CI = 1.169-1.571, p < 0.01), and transfer rate (aOR = 2.176, 95 CI = 1.257-3.768, p = 0.01). In IBR, African Americans had higher superficial wound complications (aOR = 1.303, 95 CI = 1.01-1.681, p = 0.04), flap revision (aOR = 4.19, 95 CI = 1.229-14.283, p = 0.02), and hemorrhage/hematoma (aOR = 1.791, 95 CI = 1.401-2.291, p < 0.01). In both ABR and IBR, African Americans had longer hospital length of stay (p < 0.01). These results highlight evident racial disparities in breast reconstruction for African Americans. Targeted interventions are needed to guarantee equitable access to breast reconstruction services and to address postoperative complications in African Americans.

Conceptualizing Scaffold Guided Breast Tissue Regeneration in a Preclinical Large Animal Model.

Scaffold-guided breast tissue regeneration (SGBTR) can transform both reconstructive and cosmetic breast surgery. Implant-based surgery is the most common method. However, there are inherent limitations, as it involves replacement of tissue rather than regeneration. Regenerating autologous soft tissue has the potential to provide a more like-for-like reconstruction with minimal morbidity. Our SGBTR approach regenerates soft tissue by implanting additively manufactured bioresorbable scaffolds filled with autologous fat graft. A pre-clinical large animal study was conducted by implanting 100 mL breast scaffolds (n = 55) made from medical-grade polycaprolactone into 11 minipigs for 12 months. Various treatment groups were investigated where immediate or delayed autologous fat graft, as well as platelet rich plasma, were added to the scaffolds. Computed tomography and magnetic resonance imaging were performed on explanted scaffolds to determine the volume and distribution of the regenerated tissue. Histological analysis was performed to confirm the tissue type. At 12 months, we were able to regenerate and sustain a mean soft tissue volume of 60.9 ± 4.5 mL (95% CI) across all treatment groups. There was no evidence of capsule formation. There were no immediate or long-term post-operative complications. In conclusion, we were able to regenerate clinically relevant soft tissue volumes utilizing SGBTR in a pre-clinical large animal model.
