Long-term Survival Outcomes in Locally Advanced Breast Cancer after Mastectomy with or without Breast Reconstruction.

There is ongoing debate about the safety of breast reconstruction for patients with locally advanced breast cancer (LABC) who have undergone total mastectomy (TM). More and more LABC patients are undergoing breast reconstruction after TM, but its long-term survival outcomes remain unclear. This study aims to compare the survival outcomes of LABC patients who underwent breast reconstruction after TM with those who did not, based on a large sample. We collected data for all LABC patients who underwent TM with or without breast reconstruction in the Surveillance, Epidemiology, and End Results (SEER) database. We divided patients into two groups: TM group and total mastectomy with reconstruction (TM+R) group. The primary outcomes were overall survival (OS) and breast cancer-specific survival (BCSS). Propensity score matching (PSM) analysis was used to eliminate imbalances of baseline data between the in tow groups. Data were analyzed using chi-square tests, Kaplan-Meier methods, and univariate and multivariate cox regression analyses. We identified 39,112 eligible patients (33,169 patients received TM and 5,943 received TM+R), and 8,680 patients were matched after PSM (4,340 patients received TM and 4,340 received TM+R). Patients with middle age, white, married, lived in urban, IIB-IIIA stage, invasive ductal carcinoma (IDC), pathological grade II-III, hormone receptor positive, and undergone chemotherapy were more likely to receive breast reconstruction. After PSM, Kaplan-Meier survival analysis showed better OS and BCSS in the TM+R group versus the TM group (OS:P<0.001; BCSS: P=0.008). Multivariate cox regression analysis showed that TM+R significantly improved OS and BCSS (OS: hazard ratio (HR) 0.73, 95% CI [0.68,0.79], P<0.001; BCSS: 95% CI [0.79,0.94], P=0.001). Subgroup analysis showed that patients with old age, white, and hormone receptor positive had better OS and BCSS by TM+R compared to TM. Breast reconstruction after total mastectomy is associated with better OS and BCSS in patients with LABC.

Impact of breast reconstruction on quality of life in women undergoing mastectomy for breast cancer: a systematic review and meta-analysis using the Breast-Q questionnaire

Introduction: Post-mastectomy breast reconstruction is crucial in breast cancer treatment; however, its impact on women’s quality of life (QOL) remains inadequately understood. The BREAST-Q questionnaire is used for assessing QOL related to breast surgery. Therefore, this study aimed to determine whether there are differences in QOL between women undergoing mastectomy with and without breast reconstruction using the BREAST-Q questionnaire. Methods: We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines and registered in PROSPERO. Articles in English, Portuguese, or Spanish were included, and studies on prophylactic mastectomy or breast-conserving surgery, duplicate studies, duplicate data, articles without original data (reviews, editorials, case reports, technical reports) and those without breast reconstruction were excluded. A comprehensive search was conducted across nine scientific databases. The defined search strategy was related to the terms standardized by the MeSH/PubMed controlled vocabularies, including Medical Subject Headings (MeSH), Embase subject headings (Emtree), and their synonyms. Statistical heterogeneity was assessed using the chi-squared and inconsistency tests. Statistical analyses were performed using the R software. A meta-analysis was performed for each BREAST-Q domain when data from multiple studies were available. Results: Of 1266 studies identified, three with 611 participants were included in the meta-analysis. Of these participants, 248 underwent mastectomy without reconstruction and 363 underwent post-mastectomy breast reconstruction. The meta-analysis revealed significantly higher scores in the domains “satisfaction with the breast,” “physical well-being of the chest,” “psychosocial well-being,” and “physical well-being” in women who underwent breast reconstruction compared with those who did not. Conclusion: This study demonstrates a positive association between breast reconstruction and enhanced QOL in women undergoing breast cancer treatment and mastectomy. Patient-reported outcome measures using questionnaires, such as Breast-Q, can elucidate satisfaction levels with the reconstruction, which will likely improve continuously with advances in modern plastic surgery.

"Legislative Impact and Persistent Disparities: Post-Mastectomy Breast Reconstruction Rates in the United States Among 224,506 Patients".

Breast reconstruction following mastectomy for the treatment of breast cancer restores form and enhances patient satisfaction. The Affordable Care Act (ACA) of 2010 aimed to impact trends in breast reconstruction, but recent information regarding racial and ethnic disparities is lacking. We analyzed National Surgical Quality Improvement Program (NSQIP) data spanning 2005-2022 to investigate the impact of ACA on racial and ethnic diversity in immediate breast reconstruction post-mastectomy. Patient demographics, including race and ethnicity, were considered. Statistical analyses included Pearson chi-square tests and multivariable logistic regressions to assess trends and disparities over time. In total, 224,506 patients met inclusion criteria. Analysis revealed that in the pre-ACA era, American Indian or Alaska Native, Asian, and Black or African American individuals underwent immediate breast reconstruction at lower rates compared to White patients (P < 0.001). Additionally, Hispanic patients were less likely to undergo breast reconstruction compared to non-Hispanic patients (28.0% vs 33.4%; P < 0.001). In the post-ACA period, this trend persisted with all racial groups undergoing immediate breast reconstruction at lower rates compared to White patients (P < 0.001). However, Hispanic patients were more likely to undergo immediate breast reconstruction compared to non-Hispanic patients (53.8% vs 47.9%, P < 0.001). Despite legislative efforts and a steady increase in immediate breast reconstruction rates over the years, racial disparities in breast reconstruction rates persist, highlighting the need for ongoing monitoring and targeted interventions to ensure equitable reconstructive care for all patients.

Breast Reconstruction in Patients with Prior Breast Augmentation: Searching for the Optimal Reconstructive Option.

Background and Objectives: Breast cancer in patients with prior breast augmentation poses unique challenges for detection, diagnosis, and management. Mastectomy rates are increasing, and patients with prior augmentation often have a lower body mass index, making autologous techniques unsuitable. This study aims to assess the best reconstructive option in patients with a history of subglandular or dual-plane breast augmentation. Materials and methods: A prospective analysis was conducted on patients who underwent breast reconstruction after mastectomy. Patients with subglandular or dual-plane breast augmentation were included. Patients were divided into submuscular breast reconstruction (Group 2) or prepectoral breast reconstruction (Group 1) groups. Demographic and surgical data were collected. Results: A total of 47 patients were included, with 23 in Group 1 and 24 in Group 2. Complications occurred in 11 patients (23.4%), with significant differences between groups. The most common complication was seroma formation. Implant loss occurred in 4.3% of cases in Group 1, while no implant loss was observed in Group 2. Patient-reported satisfaction scores were similar between groups at 12 months postoperatively. Conclusions: Subpectoral breast reconstruction with a tissue expander seems a safer and effective technique for patients with prior breast augmentation. It resulted in fewer complications. This approach should be considered as an option for breast reconstruction after mastectomy in this cohort of patients.

Intraoperative Hypothermia Versus Normothermia in Breast Reconstruction: A Systematic Review and Meta-Analysis.

Despite advancements in breast reconstruction, the precise impact of intraoperative hypothermia on postoperative complications remains unclear. Recent literature suggests that intraoperative hypothermia is a risk factor for impaired wound healing and increases the incidence of surgical site infections. This study examines the effect of intraoperative hypothermia on postoperative outcomes in breast reconstruction. We searched PubMed, Embase, and Cochrane Library for studies comparing hypothermia with normothermia in breast reconstruction. A meta-analytical method was employed to estimate the risk of postoperative complications among patients undergoing breast reconstruction. Data synthesis employed the random-effects models, presenting the results as risk ratio (RR) with corresponding 95% confidence intervals (CIs). Statistical analysis was performed using Review Manager 5.4 (Cochrane Collaboration), and heterogeneity was assessed using I2 statistics. Four studies meeting our inclusion criteria were included in the meta-analysis, comprising 871 participants. The average age and body mass index were 52.98 years and 27.76 kg/m2, with a follow-up duration of 3-6 months. In our analysis, intraoperative hypothermia was associated with an increase in the incidence of wound healing complications in breast reconstruction (RR 1.68; 95% CI 1.24 to 2.27; p = 0.0008). Despite lower incidence of infection, hematoma, seroma, and necrosis in the hypothermia group, no significant differences were observed. Our meta-analysis assessing intraoperative hypothermia in breast reconstruction indicates that hypothermia is a significant risk factor for wound healing complications.

8550 Processing Technique Affects Aromatase Expression in Fat Grafts for Breast Reconstruction

Abstract Disclosure: S. Arbuiso: None. Y. Chen: None. N.A. Vernice: None. A. Zhang: None. I.J. Rhodes: None. C.C. Alston: None. S. Hanif: None. S. Liu: None. P. Bhardwaj: None. D. Janhofer: None. G.G. Black: None. D.M. Otterburn: None. K.A. Brown: None. Introduction: Autologous fat grafting is commonly used in breast reconstruction as it is associated with good cosmetic outcomes, high patient satisfaction, and minimal risks. Adipose tissue is known to support cancer growth via the secretion of adipokines and the modulation of estrogen levels due to aromatase expressed in adipose stromal cells. A higher body mass index (BMI) and postmenopausal status are associated with higher levels of aromatase. With novel processing techniques being developed to increase fat graft retention, there is a need to better understand how these will affect the biology of lipoaspirates for women who have previously had breast cancer. This study aims to assess how different processing techniques used in fat grafting (1) impact aromatase gene expression, (2) affect breast cancer cell proliferation, and (3) affect the cellular composition of the engrafted lipoaspirate. Methods: Patients who underwent breast reconstruction for breast cancer treatment or for prophylactic measures, and were receiving autologous fat grafting, were enrolled in a prospective randomized controlled trial (NCT04891510). Patients were randomized to one of three processing techniques: standard decantation, active filtration, and low-pressure decantation. Conditioned media (CM) was created from each sample. Aromatase mRNA was measured in the lipoaspirate using qRT-PCR for aromatase (CYP19A1) and related to patient BMI or menopausal status. The effect of CM on the proliferation of MCF7 cells (estrogen receptor positive (ER+) breast cancer cell line) was measured using CyQUANT. Formalin-fixed lipoaspirate samples were embedded in HistoGel and paraffin. Adipocyte diameter was measured in hematoxylin and eosin (H&amp;E) stained sections using ImageJ. Results: Aromatase mRNA levels were correlated with BMI and were higher in postmenopausal women (p≤0.05), with the standard decantation group demonstrating a stronger correlation with BMI. Samples processed via active filtration were associated with weaker correlations between aromatase gene expression and BMI and menopausal status. CM induced MCF7 cell proliferation to a similar extent to cells plated in fetal bovine serum-containing media. There was no difference in proliferation patterns between treatment groups. Upon histological assessment, adipocytes were intact, and adipocyte diameter was significantly correlated with patient BMI. Conclusion: Lipoaspirate may contain factors that promote breast cancer cell proliferation, unaffected by processing technique. Caution should be used to ensure local control of the cancer has been achieved prior to reconstruction. Our data suggest that active filtration selects for a lower percentage of adipose stromal cells, which may be beneficial for patients who previously had ER+ breast cancer. Presentation: 6/1/2024

Nipple-Areola Complex Reconstruction Using FixNip NRI Implant after Mastectomy: An Innovative Technique.

Nipple-areolar complex reconstruction is the final stage of breast reconstruction, and it improves quality of life in patients with post-mastectomy breast cancer. We present a case of a patient with breast cancer underwent breast reconstruction and subsequent nipple-areolar complex reconstruction with an innovative biocompatible smooth silicone implant specially designed for a long-lasting restoration of the nipple-areola complex called FixNip NRI. However, to our knowledge, nipple-areolar complex reconstruction with FixNip was not previously reported. We present an emerging technique applied on a patient with breast cancer treated with skin-sparing mastectomy and with immediate breast reconstruction using an expander and then exchanged expander to breast implant. FixNip nipple reconstruction implant is implanted for the reconstruction of the areola-nipple complex with local-regional anaesthesia. She did not develop any postoperatively short-term or long-term complications, and her nipple slowly underwent to a gradual and better definition of its profile. This new approach regarding the reconstruction of the nipple-areola complex seems to be very promising in relation to both the degree of aesthetic satisfaction of patients and the ease of use by surgeons.

Quality of life in breast reconstruction: a comparison of lightweight and conventional breast implants.

Due to the declining mortality rates of breast carcinoma and the rising incidence of risk-reducing mastectomies, enhancing the quality of life after breast reconstructions has become an increasingly important goal. The advantages of lightweight breast implants (B-Lite®) may significantly contribute to achieving this objective. This study aims to investigate whether lightweight implants are suitable for patients undergoing breast reconstruction and could improve the quality of life in comparison to conventional implants. In this study, we retrospectively analyzed 48 patients (38 implants in each group) who underwent implant-based breast reconstruction with either B-Lite® or conventional breast implants between 2019 and 2022 at the University Center for Plastic Surgery in Regensburg. As part of the postoperative follow-up, a clinical examination and a survey using the Breast-Q® questionnaire were conducted to evaluate the postoperative quality of life. The implants used were similar in weight and shape. On average, the B-Lite® implants had a higher implant volume and patients in this group had a slightly higher BMI. Patients who received B-Lite® implants showed a significantly better result regarding the sensation of sensitivity in the surgical area and the scar formation also appeared to be more favorable. However, patients with B-Lite® implants perceived their implants as more uncomfortable than those with conventional breast implants. In other terms concerning quality of life, both groups appeared similar. In summary, there are confounding factors that could influence the outcome of some aspects in this study, which could not be avoided due to the retrospective study design and the temporary suspension of B-Lite implants. Nevertheless, as the first of its kind, this study demonstrated that B-Lite implants could also be suitable for usage in breast reconstructions, thus providing an important foundation for further prospective studies to build upon.

Finnish translation, validation, and reproducibility of BREAST-Q modules relevant to breast cancer treatment

Background and objective: Breast cancer and its treatments can have a marked impact on the patient health-related quality of life. The aim of this study was to produce and validate Finnish versions of the breast-conserving treatment, mastectomy and breast reconstruction modules of the BREAST-Q, a patient-reported outcome tool designed specifically for women undergoing treatment for breast cancer. Methods: The relevant BREAST-Q modules were translated to Finnish according to established guidelines. Altogether 777 preoperative women were recruited at the Breast Surgery Unit and the Plastic Surgery Unit of Helsinki University Hospital between December 2019 and March 2021. This included 541 patients scheduled for breast-conserving surgery, 86 for mastectomy, and 150 for breast reconstruction. Postoperative patients were recruited through a postal survey, approaching 500 women operated for breast cancer in 2017, including 250 women who had undergone breast-conserving surgery and 250 women who had undergone mastectomy, as well as 339 women who had undergone breast reconstruction between August 2017 and July 2019. The patients were invited to fill the BREAST-Q modules relevant to their treatment and the general health-related quality-of-life instrument SF-36. A repeat administration of the BREAST-Q was done 2 weeks later. Results: A total of 665 (41%) women participated in the study, 339 (44%) preoperatively and 326 (39%) postoperatively. The BREAST-Q subscales showed high internal consistency with most Cronbach’s alphas &gt; 0.8. The repeatability of the subscales was excellent with most intra-class correlation coefficients &gt; 0.75. Low or negligible correlation was observed between BREAST-Q subscales and SF-36 domains. Conclusions: The Finnish version of the BREAST-Q modules breast-conserving treatment, mastectomy, and breast reconstruction performs well in assessing the health-related quality of life of women undergoing surgery for breast cancer or breast reconstruction.

Noninvasive visualization of the midline-crossing arterial variation in the deep inferior epigastric artery perforator flap using photoacoustic tomography for application in patients with abdominal scars

BackgroundThe importance of the subcutaneous arterial network crossing the midline in transverse abdominal flaps has been reported. Photoacoustic tomography can be used to noninvasively visualize subcutaneous vascular networks. We applied this novel technology preoperatively in patients undergoing breast reconstruction to detect individual variations in the midline-crossing arteries. MethodsSix patients scheduled to undergo breast reconstruction using free deep inferior epigastric artery perforator flaps were examined. Each scan of the 12×8-cm region took approximately 8min. The accuracy of the tentative arteries evaluation defined by photoacoustic tomography was compared with the arterial phase detected by intraoperative indocyanine green angiography. The number of perforator vessels used for the flap, surgical time for flap elevation, and perfusion area ratio were compared with those of the control group. ResultsThe average match rate between tentative arteries prediction by photoacoustic tomography and arterial-phase assessment by intraoperative angiography in 5 patients was 79.8%. Each midline crossing artery showed individual variations. The photoacoustic tomography group (PAT-1 to 5) showed 1.8 perforators per flap, 163minutes for flap elevation, and 93% perfusion area, with no significant differences from the control group (N=5). A 63-year-old woman (PAT-6) with abdominal scars, including a midline abdominal incision, showed a preserved midline crossing artery. The planned single perforator deep inferior epigastric perforator flap was successfully applied to the contralateral perfusion area. ConclusionsPhotoacoustic tomography noninvasively visualizes the subcutaneous midline-crossing arterial networks. Understanding individual vascular variations can support preoperative planning and surgical indication of abdominal flaps, especially in patients with postsurgical scars.

Potential of the Thoracoepigastric Vein as a Drainage Vein in Breast Reconstruction With a Free Flap: An Anatomical Study Using Computed Tomography.

The recipient vessel choice is very important when performing free-flap breast reconstructions. Usually, the concomitant vein of the recipient artery is anastomosed, and mismatches in the diameter are occasionally observed. We consider the thoracoepigastric vein (TEV) as a potential useful recipient vein. The use of the TEV is not a novel technique. It has been used by surgeons for free-flap anastomoses in the axillary region, but usually as an anastomotic site for the second vein. However, anatomical findings such as TEV diameter, its deficiency rate, and influence on mastectomy are not clear. In this study, computed tomography (CT) was performed to evaluate the use of the TEV as a recipient vein for breast reconstruction. The medical records of patients who underwent breast reconstruction with free-flap transfer were retrospectively evaluated. In most cases, CT was performed using a tissue expander inserted after mastectomy. The TEV was considered suitable if its diameter on the mastectomy side was >1 mm and the vertical distance from the most distal slice level where the TEV could be seen at the third costal cartilage height of the parasternal region was <50 mm. Sixty-six sides of 33 patients were evaluated. The mean age of the patients was 49.3 ± 5.1 years. The TEV was used in five flaps. TEV diameters were not significantly different between the left and right sides (1.85 ± 0.53 vs. 1.82 ± 0.6, respectively, p = 0.836). On the mastectomy side, eight (25%) TEVs were injured, but only three (8.6%) were considered unavailable. On the healthy side, 96.4% TEVs were available. TEVs may be a good choice as vein anastomosis targets for breast reconstruction with a free flap because of their relatively large vessel diameter. UMIN-CTR: R000061573.

Cultural Influences on the Receipt of Breast Reconstruction: a Scoping Review.

Post-mastectomy breast reconstruction can provide breast cancer patients with lasting psychosocial, functional, and body image benefits. While sociodemographic factors affecting the receipt of breast reconstruction have been well studied, the cultural factors influencing patients' decisions to undergo breast reconstruction remain unclear. There are currently no reviews on cultural factors influencing breast reconstruction decision-making. This scoping review aimed to broadly evaluate the current literature on cultural factors that influence the receipt of breast reconstruction in breast cancer patients who have undergone mastectomies. A combination of keywords and subject headings was used to search for articles related to breast reconstruction and decision-making. Databases were searched from inception to November 20, 2023. Screening was performed according to PRISMA-ScR guidelines and quantitative studies examining the receipt of breast reconstruction in breast cancer patients following mastectomy were evaluated for inclusion. Of the 4,520 studies that underwent screening, 61 studies were included in the final review. The majority of studies included in the review were retrospective studies and studies in the United States. Included studies were evaluated for cultural influences on the receipt of breast reconstruction. Six themes emerged across the included studies: race and ethnicity, language and communication barriers, education and literacy, cultural competency, patient perceptions, and family and relationships. In addition to well-established influences on breast reconstruction like race and ethnicity, this review broadly identified additional cultural factors that influence patients' decisions to undergo breast reconstruction.

Strategically shifting paradigms: the new era of DIEP flaps with minimally invasive mastectomy: a retrospective cross-sectional study

BackgroundThe free deep inferior epigastric artery perforator (DIEP) flap is the gold standard in autologous breast reconstruction. Asian patients often present with a smaller body mass index with relatively insufficient tissue. To restore appropriate symmetry, a larger flap inset ratio must be transferred. Supercharging of the second vein or inclusion of bilateral pedicle is commonly required. Current paradigm shifts in mastectomy has also resulted in more minimally invasive surgeries (MIS) espousing smaller lateral incisions, leading to a significant change in available recipient vessels. This study aimed to demonstrate our experience in changing strategies of DIEP flaps following the evolution of mastectomy techniques.MethodsBetween October 2008 and March 2022, retrospective data was gathered for 278 patients who underwent breast reconstruction surgery utilizing DIEP flaps by a single plastic surgeon. These patients were divided into two distinct groups based on their operation dates, with November 2018 marking a pivotal moment when the first MIS, including endoscopic-assisted and robot-assisted mastectomy, was introduced.ResultsA total of 278 patients were included. Bipedicle vessel utilization for flap supercharge saw a significant increase (15.9% vs. 7%, p < 0.001), while the use of the superior inferior epigastric vein (SIEV) decreased (5.1% vs. 17.1%, p = 0.01). Preceding MIS, SIEV was the primary choice for flap supercharge (96.0%, p < 0.001), whereas post-introduction, the contralateral DIEP pedicle gained prominence (75.9%, p < 0.001). There was also an increased utilization of thoracodorsal artery and lateral thoracic artery following MIS.ConclusionThese findings underscore the profound impact of MIS on the strategic choices made in DIEP flap-based breast reconstruction.Trial registrationThis study is retrospectively registered on ClinicalTrials.gov (NCT06321549).

A case of BIA-ALCL in which postoperative chest wall recurrence was highly suspected: the third reported case of BIA-ALCL in Japan

BackgroundBreast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare malignancy. Many cases of BIA-ALCL are identified based on the presence of late-onset effusion and/or masses. Importantly, the United States Food and Drug Administration noted that in all cases diagnosed in patients with textured implants, the patients either had a history of mixed implantation of smooth and textured devices or no clinical history was supplied for review. In Japan, the first case of BIA-ALCL was reported in 2019, and we encountered the third case in Japan in December 2021. There have been a total of five cases of BIA-ALCL previously reported at Japanese academic conferences (Japan Oncoplastic Breast Surgery Society. http://jopbs.umin.jp/medical/index.html), of which only the first case has been published. Unlike the first case, this patient had clinical features that were highly suggestive of the postoperative chest wall recurrence of breast cancer, with a mass and rash on the skin.Case presentationThe patient was a 45-year-old woman who had undergone breast reconstruction after breast cancer surgery of the right breast 8 years previously. The patient presented with a mass and skin rash inside the inframammary area, and we suspected a damaged silicone breast implant (SBI) or chest wall recurrence. We examined the mass by a core needle biopsy and made a pathological diagnosis of BIA-ALCL. Imaging findings suggested internal thoracic lymph node swelling and lymphoma infiltration beyond the capsule but no metastatic lesions (cStage III). After en bloc resection of the SBI and lymphoma, adjuvant systemic therapy was performed.ConclusionWe encountered the third case of BIA-ALCL in Japan. This was a case with clinically advanced stage of disease; however, the BIA-ALCL was found to be in remission.

Less Is More: The Role of Mesh in Microsurgical Breast Reconstruction with Abdominal Flaps.

The use of mesh to reinforce the abdominal wall after abdominal flap harvest has been reported to decrease the risk of bulging and herniation. However, the impact of the plane of mesh placement in relation to the anterior rectus sheath (vs. no mesh) on postoperative abdominal complications remains unclear. We retrospectively analyzed the length of stay and clinical outcomes in 158 female patients who underwent breast reconstruction with 250 free abdominal flaps. Group 1 consisted of patients who underwent polypropylene sublay-onlay ("sandwich") mesh placement (N = 70) versus polypropylene sublay-only mesh (group 2; N = 54) versus primary fascial repair without mesh (group 3; N = 34). Patient demographics and comorbidities were comparable between study groups, except for rates of neoadjuvant chemotherapy (group 1: 53% vs. group 2: 33% vs. group 3: 24% [p < 0.01]), postoperative follow-up in months (group 1: 21.5; group 2: 11.5; group 3: 7.6 [p < 0.01]), and length of stay in days (group 1: 4.9 vs. group 2: 4.4 vs. group 3: 3.3 [p < 0.01]). No differences were observed in breast flap and donor-site complications between study groups. Patients in group 3 required significantly lower oral morphine equivalent units postoperatively compared with those in groups 1 and 2 (group 1:185.5 vs. group 2: 79.7 vs. group 3: 71.6 [p < 0.01]). Abdominal donor-site closure without mesh was associated with a shorter length of stay and less narcotic intake without an increase in donor-site complications. These findings should be considered when deciding to place mesh for donor-site closure after abdominal flap harvest.

The Combined Bra-Line Back-Lift Latissimus Flap (BLBL-LAT Flap) for Aesthetic Breast Reconstruction and Simultaneous Back Contouring.

The latissimus dorsi pedicled ('LAT') flap has been a workhorse flap for breast reconstruction for many decades. The asymmetric back scar has been a major source of complaint. In patients with excess back adiposity, we can utilize the skin paddle harvest to improve back contour. We combined the principles of the esthetic bra-line back-lift with the LAT flap to provide simultaneous improvement of both posterior upper trunk adiposity and skin excess, which together form 'back rolls', using a concealed scar. To establish a new surgical technique of combined bra-line back lift with latissimus dorsi flap ('BLBL-LAT flap') for esthetic breast reconstruction. This was an IRB-approved retrospective single-surgeon study performed in a national cancer center. We included patients undergoing breast reconstruction using combined BLBL-LAT flap between 2015 and 2023, with a minimum of 6 months follow up. 106 female patients underwent 110 breast reconstructions using BLBL-LAT flap. 75% of patients had prosthesis placement and 25% of patients were 100% autologous. Complication rates were low: 4/106 patients (3.8%) had seroma, needing surgery. Of the 78 reconstructions with implants, 3 (3.8%) had periprosthetic implant infection. One (<1%) patient had partial flap loss and no patients had complete flap loss. Four patients had bilateral BLBL-LAT flap reconstruction. Two unilateral breast reconstruction patients came back for successful symmetrizing bra-line back-lift (without LAT flap breast reconstruction). The BLBL-LAT flap allows breast reconstruction and simultaneous improvement in back contour, using a scar that can be concealed in a bra. This two-for-one procedure is of particular benefit for patients with high BMI who often have unwanted excess adiposity and laxity of the back. Since this patient population are high risk for free tissue transfer, we propose that the BLBL-LAT flap should be considered the first-line method of autologous breast reconstruction in higher BMI patients.

Patient reported outcome measures at a large district general hospital post-mastectomy and implant based reconstruction.

11 Background: Breast reconstruction surgery for cancer can be a debilitating and life changing experience for patients, with complex affects on physical and mental health throughout the rehabilitation journey. We conduct a study on a cohort of patients undergoing this procedure, with focus on patient reported outcome measures. Methods: We reviewed all patients who underwent breast reconstruction surgery at our hospital from 2017 to 20223. Demographic, diagnosis, pre- and post-operative adjuvant treatment, and implant characteristics were collected. Psychosocial well being, physical wellbeing, satisfaction with breasts scales of the BREAST-Q were used. Independent t-test was conducted to find differences between PROMs for each group, and linear regression of age and implant size on each score. Results: 69 patients were contacted and 39 PROMS collected. The average age of patients was 57.6 years old. 40% were previous or current smokers and 40.8% had BMI&gt;30. 29 had pre-pectoral placement and 40 sub-pectoral. 17 had smooth implants and 52 textured. The average size of implant was 330mm. Immediate reconstruction was associated with a lower psychosocial score (66.0vs86.9, p=0.02) compared to multi-stage implants. Sub pectoral placement was associated with a higher (75.7vs61.9 p=0.046) psychosocial score than pre pectoral placement. Textured surface was associated with lower physical score than smooth surface (34.7vs50.2 P=0.046). On linear regression, age was positively associated (p=0.007) with psychosocial score. Conclusions: These findings underscore the importance of personalized approaches in surgery, considering implant type, placement technique, and patient age. Surgeons should prioritize patient preferences and needs to optimize post-surgical satisfaction and well-being.

Hypofractionated vs Conventionally Fractionated Postmastectomy Radiation After Implant-Based Reconstruction

Postmastectomy radiation therapy (PMRT) improves local-regional disease control and patient survival. Hypofractionation (HF) regimens have comparable efficacy and complication rates with improved quality of life compared with conventional fractionation (CF) schedules. However, the use of HF after mastectomy in patients undergoing breast reconstruction has not been prospectively examined. To compare HF and CF PMRT outcomes after implant-based reconstruction. This randomized clinical trial assessed patients 18 years or older undergoing mastectomy and immediate expander or implant reconstruction for breast cancer (Tis, TX, or T1-3) and unilateral PMRT from March 8, 2018, to November 3, 2021 (median [range] follow-up, 40.4 [15.4-63.0] months), at 16 US cancer centers or hospitals. Analyses were conducted between September and December 2023. Patients were randomized 1:1 to HF or CF PMRT. Chest wall doses were 4256 cGy for 16 fractions for HF and 5000 cGy for 25 fractions for CF. Chest wall toxic effects were defined as a grade 3 or higher adverse event. The primary outcome was the change in physical well-being (PWB) domain of the Functional Assessment of Cancer Therapy-Breast (FACT-B) quality-of-life assessment tool at 6 months after starting PMRT, controlling for age. Secondary outcomes included toxic effects and cancer recurrence. Of 400 women (201 in the CF arm and 199 in the HF arm; median [range] age, 47 [23-79] years), 330 patients had PWB scores at baseline and at 6 months. There was no difference in the change in PWB between the study arms (estimate, 0.13; 95% CI, -0.86 to 1.11; P = .80), but there was a significant interaction between age group and study arm (P = .03 for interaction). Patients younger than 45 years had higher 6-month absolute PWB scores if treated with HF rather than CF regimens (23.6 [95% CI, 22.7-24.6] vs 22.0 [95% CI, 20.7-23.3]; P = .047) and reported being less bothered by adverse effects (mean [SD], 3.0 [0.9] in the HF arm and 2.6 [1.2] in the CF arm; P = .02) or nausea (mean [SD], 3.8 [0.4] in the HF arm and 3.6 [0.8] in the CF arm; P = .04). In the as-treated cohort, there were 23 distant (11 in the HF arm and 12 in the CF arm) and 2 local-regional (1 in the HF arm and 1 in the CF arm) recurrences. Chest wall toxic effects occurred in 39 patients (20 in the HF arm and 19 in the CF arm) at a median (IQR) of 7.2 (1.8-12.9) months. Fractionation was not associated with chest wall toxic effects on multivariate analysis (HF arm: hazard ratio, 1.02; 95% CI, 0.52-2.00; P = .95). Fewer patients undergoing HF vs CF regimens had a treatment break (5 [2.7%] vs 15 [7.7%]; P = .03) or required unpaid time off from work (17 [8.5%] vs 34 [16.9%]; P = .02). In this randomized clinical trial, the HF regimen did not significantly improve change in PWB compared with the CF regimen. These data add to the increasing experience with HF PMRT in patients with implant-based reconstruction. ClinicalTrials.gov Identifier: NCT03422003.

NIRO200NX: Reliable Monitoring System for Buried Deep Inferior Epigastric Perforator Flap.

The deep inferior epigastric perforator (DIEP) flap is a useful tool for breast reconstruction and tends to be transferred into the breast envelope as the buried flap from an aesthetic point of view. However, it is difficult to monitor the blood flow in the buried DIEP flap after reconstructive microsurgery. Near-infrared spectroscopy devices have recently been used for monitoring the blood flow of various organs. NIRO200NX (Hamamatsu Photonics) continuously measures the tissue oxygen index (TOI) and quickly reflects changes in flap blood flow. In this study, we investigated whether and how much the NIRO200NX applies to monitoring the blood flow of the buried flap. We included 156 patients who underwent breast reconstruction using a DIEP flap from October 2013 to May 2022, comprising 57 exposed and 99 buried-type DIEP flap cases. We measured TOI using NIRO200NX, in combination with conventional evaluation methods, including color check, pinprick test, and Doppler sound. A criterion of TOI 50 gave the best evaluations. All the 57 exposed-type flap cases showed no false evaluations, and NIRO200NX performed precise judgment. In 99 buried-type flap cases, NIRO200NX correctly evaluated 96 cases. For those buried-type cases, we found only two false-positive and one false-negative case. The misjudgments by NIRO200NX were likely caused by hematoma. We propose NIRO200NX as a reliable device for monitoring the blood flow of the DIEP flap and predicting the outcomes of breast reconstruction by the DIEP flap transfer.

Indocyanine Green Lymphography-guided Lymphatic Vessel Suture Ligation for Superficial Abdominal Flap Donor Site for Breast Reconstruction.

Autologous breast reconstruction using the abdominal flap based on the superficial system has the potential to minimize donor-site morbidity. Although efforts to improve its transfer have been focused, there have been scarce attempts to further reduce donor-site complications in the abdomen. Seroma formation is a significant complication after the superficial based abdominal flap harvest. The authors report our novel technique to address this issue. Using indocyanine green (ICG) lymphography, we identified lymphatic leakage sites in the abdominal donor site and repaired them by selective suture: ICG-guided lymphatic vessel suture ligation (ICG-LVSL). We performed ICG-LVSL for 10 patients who underwent breast reconstruction using the superficial abdominal flap and compared the incidence of seroma development between ICG-LVSL and non-LVSL groups. After propensity score matching, nine patients remained in each group. The ICG-LVSL group experienced lower incidence of seroma formation (0 versus 55%, P <0.01). The ICG-LVSL technique may be useful for reducing donor-site morbidity of the superficial abdominal flap.
