The significance of risk stratification through nomogram-based assessment in determining postmastectomy radiotherapy for patients diagnosed with pT1 - 2N1M0 breast cancer.

OBJECTIVE: To explore the high-risk factors affecting the prognosis of pT1 - 2N1M0 patients after mastectomy, establish a nomogram prediction model, and screen the radiotherapy benefit population. METHOD: The clinical data of 936 patients with pT1 - 2N1M0 who underwent mastectomy in the fourth hospital of Hebei Medical University from 2010 to 2016 were retrospectively analyzed. There were 583 patients received postmastectomy radiotherapy(PMRT), and 325 patients without PMRT. Group imbalances were mitigated using the propensity score matching (PSM) method, and the log-rank test was employed to compare overall survival (OS) and disease-free survival (DFS) between the cohorts. The efficacy of PMRT across various risk groups was evaluated using a nomogram model. RESULT: The median follow-up period was 98 months, Patients who received PMRT demonstrated significantly improved 5-year and 8-year OS and DFS compared to those who did not (P < 0.001). Multivariate analysis revealed that age, primary tumor site, positive lymph node, stage, and Ki-67 level independently influenced OS, while age, primary tumor site, and stage independently affected DFS. PMRT drastically enhanced OS in the high-risk group (P = 0.001), but did not confer benefits in the low-risk and intermediate risk groups (P = 0.057, P = 0.099). PMRT led to a significant improvement in disease-free survival (DFS) among patients in the intermediate and high-risk groups (P = 0.036, P = 0.001), whereas the low-risk group did not experience a significant benefit (P = 0.475). CONCLUSION: Age ≤ 40 years, tumor located in the inner quadrant or central area, T2 stage, 2-3 lymph nodes metastasis, and Ki67 > 30% were the high-risk factors affecting the prognosis of this cohort of patients. In OS nomogram, patients with a risk score of 149 or higher who received PMRT exhibited improved OS. Similarly, in DFS nomogram, patients with a risk score of 123 or higher who received PMRT demonstrated enhanced DFS.

Iranian Muslim women's adaptation after mastectomy.

BACKGROUND: Breast cancer is the most common malignancy among women. Women with breast cancer need to adapt all aspects of their life following their diagnosis. AIM: To investigate how women with breast cancer make adaptations in their lives to cope with the condition. METHODS: A directed content analysis was used for this study and 23 participants were interviewed. The participants included women undergoing a mastectomy and their husbands, oncologists, oncology ward nurses and psychologists. Questions were asked regarding the participants' experiences of their adaptation to a mastectomy and cancer. RESULTS: Data analysis led to the emergence of four dimensions; the physical dimension, self-concept, role-playing and interdependence. These four dimensions consisted of 21 main categories, 59 subcategories and 111 codes. CONCLUSION: The present study showed that despite the emergence of different coping approaches, women undergoing mastectomy have had various physical and mental problems that lead to role disruption. It is recommended that solutions be adopted to increase the adaptation of these patients.

Comparison of the Preoperative MRI Evaluation of Glandular Tissue in Subcutaneous Mastectomy and its Influence on the Implant Volume.

Background/Aim: This study examined the influence of preoperative MRI on the choice of implant volume in patients undergoing subcutaneous mastectomy with immediate breast reconstruction. It was postulated that preoperative MRI scans can adequately estimate glandular tissue, which in turn correlates with implant size. Patients and Methods: Preoperative and postoperative MRI scans were used in oncological and prophylactical subcutaneous mastectomy scenarios in 67 cases at the Department of Gynaecology, Breast Cancer Center, University of Cologne, Germany. The preoperative MRI was used to estimate the resected tissue and the postoperative MRI was used to scan for residual glandular tissue. In addition, a correlation found by Malter et al. in 2021 was evaluated with the available data. Results: Preoperative MRIs result in an adequate estimation of resected tissue. This in turn correlates with implant volume. The correlation by Malter et al. also holds when estimating implant volume. The likelihood of residual gland was low if the preoperatively estimate volume was removed. Conclusion: Our results indicate that the use of preoperative and postoperative MRI scans for subcutaneous mastectomies is advantageous. We suggest a routine estimation of glandular tissue, especially for small breasts.

Sexual Health in Pre-menopausal Breast Cancer Survivors.

Sexual health is often a neglected issue and affects the quality of life after treatment completion in breast cancer patients. The aim of the study was to find the incidence of sexual dysfunction and impact of mastectomy, breast conservation surgery (BCS), and hormone therapy in eligible patients on female sexuality in breast cancer survivors. It is a prospective study of 150 non-metastatic pre-menopausal BC survivors. Each participant answered the Female Sexual Function Index (FSFI) questionnaire at 4 weeks and at 3 months after completion of all therapy. Scores were compared between mastectomy and BCS patients and on hormonal therapy versus non-hormonal therapy. Chemotherapy was given to all patients and > 90% received adjuvant radiotherapy. Patients underwent both mastectomy (n = 104; 70%) and BCS (n = 46), based on imaging, staging, and patients' choice. Of the patients, 82.6% (n = 124) had sexual dysfunction at 3 months post-treatment (cutoff of 26.55). BCS survivors had significantly better scores in comparison to mastectomy survivors at 3-month interval evaluation (median 22.85 ± 2.19 versus 21.75 ± 2.09, p = 0.002). There was statistically non-significant reduction in arousal, lubrication, orgasm, pain in mastectomy survivors, and in desire, arousal, and pain in hormonal group survivors, at 3 months follow-up. Overall sexual dysfunction is high in breast cancer survivors irrespective of therapy (82.6%); however, it is more in patients undergoing mastectomy in comparison to patients undergoing conservative surgery in short-term follow-up. Sexual dysfunction issues needs to be addressed during survivorship programs, and longer follow-up is necessary to assess effect of various treatment modalities.

Phyllodes Tumors of the Breast-Experience in a Tertiary Care Center.

Phyllodes tumors (PTs) are rare neoplasms of the breast that are a challenge in clinical practice. Though mostly benign, they are notorious for local recurrence, requiring adjuvant treatments. This study was planned to report the clinicopathological features and outcomes of patients with PT treated at our center. Details of all patients who underwent surgery for PT in the last 6 years (December 2017-December 2023) were obtained from our prospectively maintained database. The demographic, clinical, radiological, pathological, and follow-up details were recorded and analyzed. Statistical analyses were carried out with Jamovi version 2.3.18. Out of 61 suspected PTs by triple assessment, 9 were excluded due to a non-phyllodes diagnosis on histopathology. We included 52 women with a mean age of 38.2 ± 11.0 years, most of whom were premenopausal (57.7%). BI-RADS 4 was the most common finding on radiological assessment (65.4%). Core needle biopsy (CNB) was the most frequently employed modality for histological diagnosis preoperatively (65.4% of cases). Wide local excisions (WLE) and mastectomies were done in 63.5% and 36.5% of patients, respectively. Benign, borderline, and malignant phyllodes constituted 67.3%, 15.4%, and 17.3% of tumors, respectively. Patients undergoing breast conservation surgery (BCS) had a significantly smaller mean tumor diameter than those who underwent a mastectomy (p < 0.001). Overall, the margin positivity rate was 34.6%. Patients undergoing mastectomy developed more local recurrence compared to WLE, although the difference was not significant (p = 0.400). The outcome following surgical excisions of large PTs in terms of margin positivity and local recurrence is the same, irrespective of whether BCS or mastectomy is done. A negative pathological margin width of > 1 mm appears acceptable. Malignant phyllodes with positive margins are associated with a higher rate of recurrence but positive margins in patients with other subtypes may not translate into recurrence, at least in the short term.

The Effects of Radiotherapy on the Sequence and Eligibility of Breast Reconstruction: Current Evidence and Controversy.

Immediate breast reconstruction (IBR) following a mastectomy, combined with radiotherapy, presents a multifaceted approach to breast cancer treatment, balancing oncological safety and aesthetic outcomes. IBR, typically involving the use of implants or autologous tissue, aims to restore breast morphology directly after a mastectomy, minimizing the psychological and physical impacts. However, integrating radiotherapy with IBR is complex due to the potential adverse effects on reconstructed tissues. Radiotherapy, essential for reducing local recurrence, can induce fibrosis, capsular contracture, and compromised aesthetic results. This narrative review covers the current trends in the sequencing of breast reconstruction and radiotherapy. We discuss patient selection, timing of radiotherapy, and reconstructive techniques, with special attention paid to quality-of-life outcomes that are increasingly reported in clinical trials. Emerging evidence supports the feasibility of IBR with careful patient selection and tailored therapeutic approaches, although ongoing research is necessary to refine protocols and enhance outcomes. Overall, IBR in the context of radiotherapy remains a promising but intricate treatment modality, requiring a nuanced balance between cancer control and aesthetic restoration.

Factors influencing prophylactic surgical intervention in women with genetic predisposition for breast cancer.

INTRODUCTION: In the United States, 5%-10% of breast cancer cases are due to genetic predisposition. Among this population, prophylactic mastectomy is viable risk-reducing option. OBJECTIVE: The objective of this study is to understand the timing to prophylactic mastectomy in patients with genetic predisposition to breast cancer and uncover factors influencing this decision. METHODS: This study is a retrospective review of patients diagnosed with genetic predisposition for breast cancer from 2010 to 2020. RESULTS: In a cohort of 506 patients with genetic predisposition for breast cancer, 154 (30.4%) underwent prophylactic mastectomy, the remainder opted for surveillance alone. The median time from diagnosis to mastectomy was 1.1 years (IQR, 0.5-3.1 years). During the surveillance period, 118 patients (33.5%) underwent breast biopsy. Of the patients with benign or atypical findings, 35 (36.8%) pursued prophylactic mastectomy, a median of 0.5 years (IQR, 0.2-1.6 years) after their gene diagnosis. The most common factor impacting the decision to undergo prophylactic mastectomy was having a family member with cancer (54.7%) followed by a personal diagnosis of other cancer(s) (27.5%). CONCLUSION: Understanding the factors influencing the decision to undergo prophylactic surgery will allow for more effective shared decision-making for primary care providers, breast surgeons, and reconstructive surgeons.

Risk-reducing surgeries for breast cancer in Brazilian patients undergoing multigene germline panel: impact of results on decision making.

PURPOSE: To assess the behavior change of high-risk breast cancer patients regarding the intention to undergo risk-reducing mastectomies (RRM) before and after genetic testing results and to identify the main influencing factors in decision-making. METHODS: Prospective cohort study conducted between November 2021 and October 2022 with women under follow-up at the high-risk outpatient clinic of the State University of Campinas (UNICAMP). Patients were referred for genetic testing, followed by counseling according to the test result. RESULTS: A total of 373 women were included. In the pre-genetic testing analysis, 54.1% of patients intended to undergo RRMs. After testing, 42.2% opted for the procedure. Behavior change occurred in 26.2%, mainly from "yes" to "no/don't know" (72,6%) (p < 0.001). The genetic test result was positive (LPV or PV) in 29.7% of patients. Among the 90 patients with positive results, 62 (68.9%) agreed to RRM, while 22 (24.4%) remained unwilling to accept RRM, regardless of the positive test. Significant influencing factors for behavior change pre- and post-genetic testing (in favor of surgery) in multivariate analysis were: positive genetic test result (OR 2.94, p < 0.001), personal cancer history (OR 2.7, p = 0.008), and ages between 40 and 49 years (OR 2.07, p = 0.008) and ≥ 50 years (OR 3.47, p < 0.001). CONCLUSION: In a Brazilian population at high-risk for breast cancer and users of the public health system, it was observed that most desired RRM, however, when genetic testing and counseling were performed, behavior change was observed, especially when the result was positive.

A surgical site abscess caused by an ant bite on foot 7 years after mastectomy: A case report.

Key Clinical Message: Abscess at a previous surgical site induced by an insect bite has rarely been reported. Here we report a case of abscess at the breast surgical site, which occurred 7 years after mastectomy following an ant bite. Abstract: Surgical site abscess generally occurs following operation within 30 days. However, surgical site abscess induced by an insect bite, which occurs several years after surgery, has rarely been reported. Here, we report a 65-year-old female patient with a history of breast cancer presenting with an abscess at the site of her mastectomy and ipsilateral arm lymphedema. Her left foot was bitten by an ant 25 days earlier and itchy red bumps with whiteheads were raised. After antibiotic treatment and abscess incision and drainage, the abscess healed, but the ipsilateral arm lymphedema persisted. This unique case demonstrates that surgical procedures can alter the susceptibility of tissues to allergic or infectious cues long after the operation.

Retrospective Analysis: Preserving More Subcutaneous Tissue Shows no Increase the Risk of Breast Cancer Recurrence.

BACKGROUND: Radical mastectomy remains the cornerstone procedure for the treatment of breast cancer (BC). However, traditional radical surgeries often lead to complications such as local numbness, pulling sensations, and atrophy of the pectoralis major muscle. In contrast, BC radical surgeries that preserve more tissue have shown potential in reducing these complications. This retrospective study aims to analyze case data from our institution, focusing on the methods of surgeries that preserve more tissue and evaluating the safety and reliability of the follow-up results. METHODS: A retrospective observational study was conducted on cases diagnosed with BC between May 2018 and July 2019 at our institution. The cases were divided into three different surgical groups and followed up for a period of 5 years. The follow-up results were then discussed within each group. RESULTS: A total of 315 cases diagnosed with BC underwent regular follow-ups. The statistical analysis revealed an average age of 45 years and an average tumor size slightly over 2.2 cm, with early-stage BC (Stage I and II) accounting for 90.2% of the cases. The overall survival (OS) and disease-free survival times in the group undergoing total mastectomy with tissue preservation were comparable to those in the traditional radical mastectomy group and the breast-conserving plus radiotherapy group. Moreover, the complication rate, particularly the incidence of chest wall numbness and pulling sensations, was lower in the total mastectomy with tissue preservation group compared to the traditional radical mastectomy group. The overall average follow-up time was 64.4 months, with a recurrence and metastasis rate of 15.6% and an OS rate of 92.7%. CONCLUSION: Based on our follow-up results, total mastectomy with more tissue preservation demonstrates comparable efficacy to breast-conserving surgery and traditional radical mastectomy. It can reduce some complications associated with traditional radical mastectomy and is beneficial for subsequent immediate and delayed breast reconstruction. This approach may be suitable for most patients with early to mid-stage breast cancer who do not wish to undergo breast-conserving surgery.

Differentiating Primary and Recurrent Lesions in Patients with a History of Breast Cancer: A Comprehensive Review.

Breast cancer (BC) recurrence remains a concerning issue, requiring accurate identification and differentiation from primary lesions for optimal patient management. This comprehensive review aims to summarize and evaluate the current evidence on methods to distinguish primary breast tumors from recurrent lesions in patients with a history of BC. Also, we provide a comprehensive understanding of the different imaging techniques, including mammography, ultrasound, magnetic resonance imaging, and positron emission tomography, highlighting their diagnostic accuracy, limitations, and potential integration. In addition, the role of various biopsy modalities and molecular markers was explored. Furthermore, the potential role of liquid biopsy, circulating tumor cells, and circulating tumor DNA in differentiating between primary and recurrent BC was emphasized. Finally, it addresses emerging diagnostic modalities, such as radiomic analysis and artificial intelligence, which show promising potential in enhancing diagnostic accuracy. Through comprehensive analysis and review of the available literature, the current study provides an up-to-date understanding of the current state of knowledge, challenges, and future directions in accurately distinguishing between primary and recurrent breast lesions in patients with a history of BC.

Acellular Dermal Matrix: Imaging Features With Histopathology Correlation.

Acellular dermal matrix (ADM) is an immunologically inert graft, typically from cadaveric skin, often used in postmastectomy breast reconstruction. Created from decellularized dermal tissues that have been treated to remove DNA and antigenic donor cells (leaving extracellular matrix), ADM is often used as a structural scaffold or sling to reinforce and support the structure and position of a breast implant during postoperative integration in implant-based breast reconstruction; ADM can also be used to fill cosmetic defects. Advantages of ADM use include improved cosmesis and reduced capsular contracture rates. On US, ADM can be seen as a subtle band with variable echogenicity adjacent to the implant. When folded on itself or redundant, ADM may present as a palpable oval mass with indistinct or circumscribed margins and variable echogenicity. On mammography, ADM can be seen as a circumscribed oval equal density mass when redundant and folded on itself; a layered appearance may be evident on tomosynthesis. On MRI, presence and absence of enhancement have been documented. Imaging findings likely vary depending on the degree of host tissue remodeling and incorporation, and when biopsied, histopathologically, ADM may be difficult to distinguish from scarring. Successful imaging diagnosis of ADM is aided by clinical knowledge of the intraoperative use and configuration of ADM, which may help differentiate ADM from new or recurrent malignancy and avoid unnecessary biopsy.

Skin Staining After Injection of Superparamagnetic Iron Oxide for Sentinel Lymph Node Dissection: A Retrospective Study of Two Protocols for Injection and Long-Term Follow-Up.

OBJECTIVE: Sentinel lymph node (SLN) dissection is a highly accurate surgical procedure allowing detection of lymph node invasion in patients with clinically negative axilla in early breast cancer. Superparamagnetic iron oxide (SPIO) is a marker used during SLN procedure, allowing the same detection rate as isotopes (Tc-99). A drawback of SPIO is skin staining that can occur around the injection site. The goal of this retrospective study was to assess the frequency of skin staining after oncological breast surgery with SPIO, and the impact of two different injection protocols on the rate of skin staining. MATERIALS AND METHODS: Data from breast cancer patients undergoing magnetic tracer SLN detection (SLND) procedure in a single department between 2020 and 2022 was reviewed. Injection protocol P1 consisted of retro-areolar injection of Magtrace 0.8 mL. Injection protocol P2, consisted of retro-tumoral injection with 1 mL. Presence of skin staining was assessed at day 10 after surgery. The evolution and satisfaction of the patients was assessed at six and 12 months. RESULTS: In total 175 sentinel lymph node biopsy procedures were performed (P1: 141/P2: 34), consisting of breast conservative surgery (BCS) (P1: 70%/P2: 53%) or mastectomy (P1: 30%/P2: 47%) with SLN. SLN detection rate was 97.7%. Skin staining was reported in 23% and occurred more often after BCS (31.6%) compared to mastectomy (6.8%). When BCS was performed, peritumoral injection was associated with a decreased risk of skin staining compared with retro-areolar injection (22.2% vs. 33.3%, respectively). When present skin staining persisted for 12 months, but most of the patients described only a slight discomfort. The low rate of discoloration after mastectomy, as previously reported, can be explained by the removal of skin and glandular tissue in which the tracer accumulates. Less skin staining in P2 may be because of a shorter interval between injection and surgery and the removal of the excess of SPIO during the lumpectomy. CONCLUSION: SPIO injection is a safe surgical technique. After mastectomy, the rate of discoloration was low. Despite the persistent skin discoloration in 58.6% in our study, patient satisfaction was high. Deeper injection, reduced doses, massage of the injection site and peritumoral injection may reduce skin staining.

Surgical treatment after augmentation mammoplasty with polyacrylamide hydrogel.

Polyacrylamide hydrogel mammoplasty is a simple and relatively affordable surgery. However, this procedure is associated with a significant frequency of late complications, prompting its suspension in 2006. Despite this, patients continue facing long-term consequences. These include hydrogel migration, changes in breast shape and volume, granulomas, fistulas, and abscess formation. The clinical case described here presents the surgical treatment after augmentation mammoplasty with polyacrylamide hydrogel performed 35 years ago.

Infiltrating Ductal Breast Carcinoma in a Male Patient With Associated BARD1 Mutation.

Male breast cancer is an uncommon diagnosis with limited research on management and prognosis due to its rarity. We discuss a case of a 55-year-old male with a non-contributory past medical history who presented with an enlarging palpable mass of his right breast tissue at the 10:00 position. The ultrasound of the right breast showed a 2.8 cm heterogenous mass with irregular borders highly suspicious for malignancy. The follow-up sonogram-guided core biopsy was performed, and the pathology of the mass confirmed high-grade infiltrating ductal carcinoma. A modified radical mastectomy of the right breast with extensive axillary lymph node excision was performed. Genetic testing of the excised tumor revealed a MUTYH gene mutation and a BARD1 (BRCA1-associated RING domain 1) gene mutation of unknown significance. Histopathological analysis confirmed a Grade 2, ER/PR-positive, KI 67-positive, and HER2-negative tumor.

Breast cancer-related lymphedema: A critical review on recent progress.

Lymphedema is a chronic and debilitating condition characterized by an abnormal buildup of protein-rich fluid in the interstitial tissue, leading to the development of edema and tissue structural alterations. Breast cancer-related lymphedema (BCRL) remains a significant healthcare burden because it can develop within days and up to 11-years after the surgery. Specifically, axillary lymph node dissection leads to 30-50 % upper limb lymphedema, which involves the accumulation of protein-rich fluid. In this article, we provide a comprehensive/critical overview of post-mastectomy lymphedema, focusing on key aspects as diagnosis, prevention, and treatment methods. Beginning with clinical condition, the article explores the pathophysiology and risk factors associated with post-mastectomy lymphedema. It further delves into various diagnostic modalities available, highlighting the importance of early detection for optimal management of BCRL. We also examine preventive strategies, emphasizing the role of patient education, lifestyle modifications, and proactive measures in reducing the risk of lymphedema development. In terms of treatment, the article covers a wide array of interventions ranging from conservative approaches like manual lymphatic drainage and compression therapy to surgical techniques such as lymph node transfer and lymphaticovenular anastomosis. Thus, through a comprehensive synthesis of current evidence and clinical practices updates, the review aims to guide healthcare professionals in delivering preventive and effective care while improving outcomes for individuals affected by post-mastectomy lymphedema.

Immediate Psychological Implications of Risk-Reducing Mastectomies in Women With Increased Risk of Breast Cancer: A Comparative Study.

BACKGROUND: Risk-reducing mastectomy is recommended for high-risk patients but may have significant psychological consequences. This study aimed to determine the differences in anxiety, depressive symptomatology, body image and quality of life in women with an increased risk of breast cancer immediately before and after undergoing risk-reducing mastectomy. METHODS: Eighty-eight women with an increased risk of breast cancer due to BRCA1/2 mutations or a previous cancer diagnosis participated in this study. Instruments used were the Hospital Anxiety and Depression Scale, Body Image Scale and the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire Core 30 and Breast 23, administered 15-30 days before and after surgery. RESULTS: Following surgery, there was an immediate and significant worsening in anxiety, depressive symptomatology and body image. There was a significant deterioration in global, physical, role, and social functioning, as well as in body image and sexual enjoyment scales. Additionally, there were increases in fatigue, nausea and vomiting, constipation, dyspnoea, insomnia, appetite loss, perceived financial difficulties, pain, systemic therapy side effects, and breast and arm symptoms. However, there was an improvement in future perspective. These changes occurred independently of whether participants had a cancer diagnosis or BRCA1/2 mutation. CONCLUSION: Risk-reducing mastectomies have immediate psychological consequences. While these procedures improve future health perspective, they increase anxiety and depressive symptomatology and decrease body image and quality of life, regardless of cancer diagnosis or BRCA1/2 mutation. These findings highlight the psychological consequences of such surgical procedures, emphasizing the need for comprehensive psychological interventions both before and after surgery.

Comparative study of muscle-sparing latissimus dorsi vs breast implants following total mastectomy.

INTRODUCTION: With 60,000 cases per year, breast cancer is the most frequent type of cancer in France, and a quarter of these cases require mastectomy. Following the surgery, breast reconstruction can be indicated. Two of the available techniques are breast implants (BIs) and muscle-sparing latissimus dorsi (MSLD). The aim of this study was to compare postoperative complications of each approach and thus help the surgeon and the patient in making an informed decision before surgery. MATERIALS AND METHODS: This descriptive, retrospective and single-centre study was conducted in the Croix Rousse hospital in Lyon (France) between 1 July 2018 and 1 July 2023. It included women aged ≥18 years who underwent mastectomy followed by (immediate or delayed) breast reconstruction with MSLD or BI. Complications were recorded and evaluated using the Clavien-Dindo classification. RESULTS: Over the course of the study, 92 patients were managed with MSLD reconstruction and 63 patients with BI. We observed a complication rate of 62% in the BI group and 39% in the MSLD group (odds ratio [OR]=0.16; p < 0.005). Body mass index (BMI) significantly impacted this rate (OR=1.11; p = 0.01), whereas smoking status and diabetes did not. No complication occurred more predominantly than others. A second surgery was required more often in the BI group (p < 0.005). There were no severe complications (>Grade 4). CONCLUSION: MSLD predicted fewer complications and was associated with a shorter hospital stay compared with implants, suggesting that it may be a preferable option for breast reconstruction.

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

BACKGROUND: The 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. METHODS: Between 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. RESULTS: A 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. CONCLUSION: These findings underscore the profound impact of MIS on the strategic choices made in DIEP flap-based breast reconstruction. TRIAL REGISTRATION: This study is retrospectively registered on ClinicalTrials.gov (NCT06321549).
