Comparison of surgical complication between immediate implant and autologous breast reconstruction after mastectomy: A multicenter study of 426 cases

Oncoplastic breast reconstruction with single-port laparoscopically harvested omental flap: insights from a ten-year tertiary center experience

PURPOSE

To evaluate the 10-year functional and oncological outcomes of single-port laparoscopically harvested omental flap (SLOF) for immediate breast reconstruction after breast cancer surgery. The technical feasibility and oncologic safety of breast reconstruction using a laparoscopically harvested omental flap remain controversial.

METHODS

We examined 236 patients with breast cancer (including 2 patients with malignant phyllodes tumors) who underwent nipple-sparing mastectomy or breast-conserving surgery followed by immediate SLOF reconstruction between February 2015 and March 2024 at our institution. Short- and long-term outcomes were assessed. Cosmetic outcomes were evaluated using a three-panel assessment and the Seoul Breast Esthetic Scoring Tool and compared with those of a matched cohort of patients who underwent deep inferior epigastric perforator (DIEP) flap breast reconstruction.

RESULTS

The rate of clinically significant complications of Clavien-Dindo grade IIIa or greater was 3.8% (9/236). Two patients with flap failure required flap removal and conversion to other reconstruction procedures. The cosmetic satisfaction rates were 82.5% and 76.4% in the SLOF and DIEP groups, respectively (P = 0.467). Over a median 59-month follow-up, the local, regional, and systemic recurrence rates were 3%, 2.1%, and 3%, respectively. All patients underwent annual screening for gastric cancer via esophagogastroduodenoscopy, and there were no cases of delayed flap removal due to gastrectomy.

CONCLUSIONS

Oncoplastic breast reconstruction using SLOF is safe and feasible. The natural contour and texture of the reconstructed breast and the nearly invisible scar at the abdominal single-port incision provide excellent cosmetic outcomes that are superior to those of other reconstruction methods.

Implants versus autologous tissue flaps for breast reconstruction following mastectomy

BACKGROUND

Women who have a mastectomy for breast cancer treatment or risk reduction may be offered different options for breast reconstruction, including use of implants or the woman's own tissue (autologous tissue flaps). The choice of technique depends on factors such as the woman's preferences, breast characteristics, preoperative imaging, comorbidities, smoking habits, prior chest or breast irradiation, and planned adjuvant therapies.

OBJECTIVES

To assess the effects of implants versus autologous tissue flaps for postmastectomy breast reconstruction on women's quality of life, satisfaction, and short- and long-term surgical complications.

SEARCH METHODS

We searched the Cochrane Breast Cancer Group's Specialised Register, CENTRAL, MEDLINE, Embase, and two trials registries in July 2022.

SELECTION CRITERIA

We included studies that compared implant-based reconstruction with autologous tissue-based reconstruction following mastectomy for breast cancer treatment or risk reduction. The minimum eligible sample size was 100 participants.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed risk of bias and extracted data using standard Cochrane procedures. We used GRADE to assess the certainty of the evidence.

MAIN RESULTS

Thirty-five non-randomised studies with 57,555 participants met our inclusion criteria. There were nine prospective cohort studies and 26 retrospective cohort studies. We judged 26 studies at serious overall risk of bias and the remaining studies at moderate overall risk of bias. Some studies measured quality of life and satisfaction using the BREAST-Q (scale of 0 to 100, higher is better). Implants may reduce postoperative psychosocial well-being compared with autologous tissue flaps (mean difference (MD) -4.26 points, 95% confidence interval (CI) -4.91 to -3.61; I² = 0%; 6 studies, 3335 participants; low-certainty evidence). Implants may reduce or have little to no effect on postoperative physical well-being compared with autologous tissue flaps, but the evidence is very uncertain (MD -1.92 points, 95% CI -4.44 to 0.60; I² = 87%; 6 studies, 3335 participants; very low-certainty evidence). Implants may reduce postoperative sexual well-being compared with autologous reconstruction (MD -6.63 points, 95% CI -7.55 to -5.72; I² = 0; 6 studies, 3335 participants; low-certainty evidence). Women who undergo breast reconstruction with implants versus autologous tissue flaps may be less satisfied with the breast, but the evidence is very uncertain (MD -8.17 points, 95% CI -11.41 to -4.92; I² = 90%; 6 studies, 3335 participants; very low-certainty evidence). This outcome refers to a woman's satisfaction with breast size, bra fit, appearance in the mirror (clothed or unclothed), and how the breast feels to touch. Women who undergo breast reconstruction with implants versus autologous tissue flaps may be less satisfied with the reconstruction (MD -5.96 points, 95% CI -10.24 to -1.68; I² = 62%; 4 studies, 1196 participants; low-certainty evidence). This outcome refers to whether the aesthetic outcome has met the woman's expectations, the impact surgery has had on her life, and whether she thinks she made the right decision to have the reconstruction. Implants may reduce or have little to no effect on the risk of short-term complications compared with autologous tissue flaps, but the evidence is very uncertain (risk ratio (RR) 0.80, 95% CI 0.63 to 1.03; I² = 91%; 22 studies, 34,244 participants; very low-certainty evidence). Implants may increase long-term complications compared with autologous tissue flaps, but the evidence is very uncertain (RR 1.56, 95% CI 1.09 to 2.22; I² = 94%; 17 studies, 26,930 participants; very low-certainty evidence). Implants may have little to no effect on the need for reintervention compared with autologous tissue flaps, but the evidence is very uncertain (RR 1.23, 95% CI 0.91 to 1.68; I² = 93%; 15 studies, 14,171 participants; very low-certainty evidence). Implants may reduce the duration of surgery compared with autologous tissue flaps, but the evidence is very uncertain (MD -125.04 minutes, 95% CI -131.41 to -118.67; I² = 0; 2 studies, 836 participants; very low-certainty evidence).

AUTHORS' CONCLUSIONS

The findings of this review show that autologous tissue-based reconstruction compared with implant-based reconstruction may improve participant-reported outcomes such as psychosocial well-being, sexual well-being, and satisfaction with the reconstruction. There is also very uncertain evidence to suggest that autologous tissue-based reconstruction increases satisfaction with the breast and reduces the risk of long-term complications compared with implants. Implant-based reconstruction may be a shorter procedure, but the evidence is very uncertain. Despite the growing demand for breast reconstruction, the best technique has not been adequately studied in randomised controlled trials (RCTs), and the evidence provided by non-randomised studies is often unsatisfactory. There is no superior breast reconstruction technique for all women. Future research should focus on the definition of decisional drivers to guide an evidence-based shared decision-making process in reconstructive breast surgery.

National Trends and In-Hospital Outcomes for Immediate Implant-Based Versus Autologous-Based Breast Reconstruction: A Propensity Score-Matched Analysis

BACKGROUND

Breast reconstruction consists primarily of two methods: autologous breast reconstruction (ABR) and implant-based breast reconstruction (IBR). Each of these methods has its advantages and disadvantages. The current study used the National Inpatient Sample (NIS), the largest inpatient database in the United States, to explore the trends, complications, and disparities in the use of IBR and ABR.

METHODS

The current study used the NIS database from 2016 to 2020, including the International Classification of Diseases, 10th version (ICD-10) codes. A propensity score-matching (1:1) analysis was used to match the IBR and ABR groups.

RESULTS

The percentage of breast reconstruction increased from 58.8% in 2016 to 63.4% by 2020. The trend of ABR was upward, and the trend of IBR was downward. In addition, the ABR group had significantly higher rates of cardiovascular complications (odds ratio [OR], 1.29), respiratory complications (OR, 4.26), vascular complications requiring surgery (OR, 7.82), blood transfusions (OR, 3.44), vasopressor need (OR, 1.409), and acute kidney injury (OR, 1.68). However, the ABR group had significantly lower rates of wound infection (OR, 0.430), wound dehiscence (OR, 0.213), wound seroma (OR, 0.602), and sepsis (OR, 0.252). A significant disparity was found in using ABR for different subgroups based on age, hospital teaching status, racial background, socioeconomic status, and hospital bed size.

CONCLUSION

The current study showed an upward trend in the utilization of ABR and a downward trend for IBR. Although ABR had a higher rate of pulmonary, cardiovascular, vascular, and bleeding complications, it had a lower rate of wound-related complications.

Autologous breast reconstruction in low- and middle-income countries (LMICs): a systematic review of current practices and challenges

INTRODUCTION

Efforts to improve global healthcare persist, yet LMICs face challenges accessing surgical care, especially breast reconstruction amidst rising breast cancer cases. This review evaluates the present state and challenges of autologous breast reconstruction in low- and middle-income countries (LMICs).

EVIDENCE ACQUISITION

Utilizing the PRISMA guidelines and the Cochrane Collaboration's standards, databases such as EMBASE, MEDLINE, Cochrane, PubMed, and Google Scholar were examined for studies on breast reconstruction in LMICs (based on the World Bank's 2022-2023 definitions) up to August 2022. Articles and case reports focusing on autologous reconstruction following breast cancer surgery in these regions were incorporated.

EVIDENCE SYNTHESIS

From an initial 288 articles, 19 met the criteria after thorough assessment. These articles documented 4899 patient cases from LMICs, with the breakdown being: 11 on LD flaps, nine on TRAM flaps, eight on DIEP flaps, two on TDAP flaps, and one on TMG flap. Flap necrosis emerged as the prevalent complication in four studies.

CONCLUSIONS

While autologous breast reconstruction presents superior aesthetic benefits without notable long-term economic setbacks, its adoption in LMICs is limited. This is partly due to the domination of implant-based methods among patients and surgeons, selected due to convenience. The scarcity of concrete evidence and standardized metrics in LMICs clouds the understanding of this procedure. Despite its advantages, awareness is low, necessitating more training and awareness campaigns. Uniform reporting, quality data, and financial analysis can provide a comprehensive LMIC understanding, aiding future research.

Effect of Perioperative Prophylactic Intravenous Antibiotic Use in Immediate Implant-Based Breast Reconstruction: A Retrospective Matched Cohort Study

Background  Among breast reconstruction methods, implant-based breast reconstruction has become the mainstream. However, periprosthetic infection is still an unresolved problem. Although published articles have revealed that limited use of antibiotics is sufficient to reduce infection rates, the number of surgeons still preferring elongated usage of antibiotics is not less. The aim of our study is to validate the appropriate duration of antibiotic use to reduce infection rate after implant-based breast reconstruction. Methods  A retrospective study reviewed medical record of 235 patients (274 implants for reconstruction) who underwent prepectoral direct to implant breast reconstruction using acellular dermal matrix wrapping technique. Infection rates were analyzed for the patients administered postoperative prophylactic antibiotics until drain removal and those who received only perioperative prophylactic antibiotics for 24 hours. Results  Of the 274 implants, 98 who were administered prophylactic antibiotics until drain removal had an infection rate of 3.06% (three implants) and 176 who received prophylactic antibiotics no longer than 24 hours postoperatively had an infection rate of 4.49% (eight implants). A total of 11 patients diagnosed with postoperative infection clinically, 8 were salvaged by antibiotic treatment, and 3 had implant removal and replacement with autologous flap. Postoperative antibiotic prophylaxis duration had no statistically significant effects in the risk of infection ( p  = 0.549). Conclusion  The duration of prophylactic antibiotics after surgery was not related to infection risk. Further study with a large number of patients, randomized control study, and route of antibiotics is needed.

Abdominal-Based Microsurgical Breast Reconstruction: How to Inset the Flap to Maximize the Aesthetic Result-A Systematic Review

Nowadays, the ultimate goal of microsurgical breast reconstruction is not merely the effective transfer of vascularized tissue but the achievement of a natural, symmetric appearance. The aim of this present study was to systematically summarize the published evidence on abdominal-based free flap inset for breast reconstruction in order to provide principles and classification that could guide the surgeon in choosing the most appropriate inset technique based on patient and flap characteristics. A comprehensive review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, looking for articles on the insetting technique for free flap breast reconstruction. After screening 306 publications, 24 papers (published from 1994 to 2020) were included in the study. We identified four main breast anatomical features on which the papers reviewed focused when describing their insetting technique: breast width, breast ptosis, breast projection, and upper pole fullness. Patient body type, type of mastectomy, and reported complications are also discussed. Flap shaping and inset during breast reconstruction are fundamental steps in any reconstructive procedure. Despite the low evidence in the current literature, this systematic review provides a framework to guide the surgeon's decision-making and optimize the aesthetic outcomes of abdominal-based free flap breast reconstruction.

Direct-to-implant versus autologous tissue transfer: A meta-analysis of patient-reported outcomes after immediate breast reconstruction

BACKGROUND

The effect of immediate implant and autologous breast reconstruction on complication rates has been studied extensively; however, the patient-reported outcomes for these procedures during immediate, one-stage reconstruction has yet to be comprehensively investigated.

OBJECTIVE

This study compared the patient-reported outcomes for immediate implant reconstruction with those associated with immediate autologous reconstruction to determine the advantages and disadvantages for each modality from the patient's perspective.

METHODS

A literature search of PubMed between 2010 and 2021 was performed, and 21 studies containing patient-reported outcomes were selected for the analysis. A meta-analysis of patient-reported outcome scores was performed separately for immediate breast reconstruction using autologous tissue transfer and synthetic implants.

RESULTS

Nineteen manuscripts were included, representing data on a total of 1342 patients across all studies. The pooled mean of patients' satisfaction with their breasts was 70.7 (95% CI, 69.4-72.0) after immediate autologous reconstruction and 68.5 (95% CI, 67.1-69.9) after immediate implant reconstruction, showing a statistically significant difference in outcomes (p < 0.05). The pooled mean of patients' sexual well-being was 59.3 (95% CI, 57.8-60.8) after immediate autologous reconstruction and 62.8 (95% CI, 60.7-64.8) after immediate implant reconstruction (p < 0.01). The pooled mean of patients' satisfaction with their outcome was 78.8 (95% CI, 76.2-81.3) after immediate autologous reconstruction and 82.3 (95% CI, 80.4-84.1) after immediate implant reconstruction (p < 0.05). The results of each meta-analysis were summarized on forest plots depicting the distribution of patient-reported outcome scores from each study.

CONCLUSIONS

Immediate reconstruction with implants may have a similar or greater capacity to achieve patient satisfaction and improve patients' QoL compared to those associated with immediate reconstruction with autologous tissue transfer when both procedures are available.

Longitudinal analysis of long-term outcomes of abdominal flap-based microsurgical reconstruction and two-stage prosthetic reconstruction

Two-stage tissue expander/implant (TE/I) and deep inferior epigastric perforator (DIEP) flaps are the two main pillars of breast reconstruction. This study aimed to conduct a longitudinal analysis of long-term outcomes after immediate DIEP- and TE/I-based reconstruction. This retrospective cohort study included patients with breast cancer who underwent immediate DIEP- or TE/I-based reconstruction between 2012 and 2017. The cumulative incidence of major complications, defined as unplanned reoperation/readmission due to complications, was analyzed by the reconstruction modality and its independent association. In total, 1,474 cases (1,162 TE/I and 312 DIEP cases) were analyzed, with a median follow-up of 58 months. The 5-year cumulative incidence of major complications was significantly higher in the TE/I group (10.3% vs. 4.7%). On the multivariable analyses, the use of DIEP flap was associated with a significantly reduced risk of major complications compared to that of TE/I. A more prominent association was observed in the analysis of patients who received adjuvant radiotherapy. Restricting analysis to those who received adjuvant chemotherapy revealed no differences between the two groups. The rate of reoperation/readmission for improving aesthetic outcomes was similar in the two groups. Long-term risks for unexpected reoperation/readmission may differ between DIEP- and TE/I-based immediate reconstruction.

Investigating the Severity of Complications following Mastectomy and Prepectoral Implant-Based versus Autologous Reconstruction

BACKGROUND

Several clinical studies have reported autologous breast reconstruction (ABR) to be associated with a higher postoperative complication rate; however, few have investigated the impact of reconstructive modality on complication severity. This study examines the impact of reconstructive modality on complication severity in a matched cohort of patients who underwent ABR versus implant-based breast reconstruction (IBR).

METHODS

A retrospective study of patients who underwent nipple-sparing mastectomy with immediate reconstruction was performed. Propensity score matching ensured adequate matching of patients who underwent ABR and staged prepectoral IBR, respectively. Patient demographics, breast measurements, and postoperative outcomes (including the incidence and severity of complications) were analyzed. Multivariable logistic regression analysis was performed. P < 0.05 was considered significant.

RESULTS

One hundred twenty-eight patients (214 breast reconstructions) were included for analysis (ABR, n = 64; IBR, n = 64). No difference in overall complication rate was noted ( P = 0.61). However, a significant association of IBR with major complications was noted ( P = 0.02). In contrast, minor complications were significantly more frequent following ABR ( P = 0.04).

CONCLUSIONS

Although the reconstructive modality did not appear to have an effect on the overall complication rate, it did significantly affect the severity of postoperative complications, with major and minor complications being associated with IBR and ABR, respectively. These findings are relevant to patient-centered decision-making, as they provide further granularity regarding postoperative complications and address the issue of complication severity.

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

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

Methods

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

Results

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

Conclusion

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

Single Institution Evolution in Defining an Algorithm for Prevention and Management of Severe Complications in Direct-to-Implant Breast Reconstruction

BACKGROUND

Complications including infection and wound dehiscence are major concerns for direct-to-implant (DTI) breast reconstruction. However, the risk factors associated with severe complications and implant salvage remain unclear.

METHODS

Retrospective study of all patients undergoing unilateral DTI breast reconstruction from 2014 through 2019. The risk factors associated with complications and prosthesis explantation were identified using multivariate logistic regression modeling and interaction analyses.

RESULTS

Among 1027 patients enrolled, 90 experienced severe complications, 41of which underwent prosthesis explantation, while 49 were successfully salvaged. Multivariate analysis demonstrated that patients with larger implant size (p=0.003), use of bovine mesh (p<0.001), adjuvant radiotherapy (p=0.047), low plasma albumin (p=0.013), and elevated blood glucose (p=0.006) were significantly more likely to suffer complications. Adjuvant radiation (OR: 7.44; 95%CI, 1.49-37.18; p = 0.014) and obesity (OR, 4.17; 95%CI, 1.17-14.88; p = 0.028) had significantly lower rates of implant salvage as well as surgical site infection (SSI) and wound dehiscence, while mastectomy skin flap necrosis was not associated with device explanation. There were no differences in complication and explantation rates between nipple-sparing and skin-sparing mastectomies. However, the combined impact of SSI and wound dehiscence added over fourteen-fold higher risk of prosthesis explantation (95%CI, 9.97-19.53).

CONCLUSION

Success in direct-to-implant breast reconstruction is multifactorial. Larger implant size, adjuvant radiation therapy, diabetes, and malnutrition demonstrate increased risk of complications in the DTI approach. Surgical site infections and wound dehiscence should be treated aggressively, but the combination of both complications portends poor salvage rates.

Robot-Assisted Minimally Invasive Breast Surgery: Recent Evidence with Comparative Clinical Outcomes

In recent times, robot-assisted surgery has been prominently gaining pace to minimize overall postsurgical complications with minimal traumatization, due to technical advancements in telerobotics and ergonomics. The aim of this review is to explore the efficiency of robot-assisted systems for executing breast surgeries, including microsurgeries, direct-to-implant breast reconstruction, deep inferior epigastric perforators-based surgery, latissimus dorsi breast reconstruction, and nipple-sparing mastectomy. Robot-assisted surgery systems are efficient due to 3D-based visualization, dexterity, and range of motion while executing breast surgery. The review describes the comparative efficiency of robot-assisted surgery in relation to conventional or open surgery, in terms of clinical outcomes, morbidity rates, and overall postsurgical complication rates. Potential cost-effective barriers and technical skills were also delineated as the major limitations associated with these systems in the clinical sector. Furthermore, instrument articulation of robot-assisted surgical systems (for example, da Vinci systems) can enable high accuracy and precision surgery due to its promising ability to mitigate tremors at the time of surgery, and shortened learning curve, making it more beneficial than other open surgery procedures.

Implant-based versus Autologous Reconstruction after Mastectomy for Breast Cancer: A Systematic Review and Meta-analysis

For women undergoing breast reconstruction after mastectomy, the comparative benefits and harms of implant-based reconstruction (IBR) and autologous reconstruction (AR) are not well known. We performed a systematic review with meta-analysis of IBR versus AR after mastectomy for breast cancer.

Methods

We searched Medline, Embase, Cochrane CENTRAL, CINAHL, and ClinicalTrials.gov for studies from inception to March 23, 2021. We assessed the risk of bias of individual studies and strength of evidence (SoE) of our findings using standard methods.

Results

We screened 15,936 citations and included 40 studies (two randomized controlled trials and 38 adjusted nonrandomized comparative studies). Compared with patients who undergo IBR, those who undergo AR experience clinically significant better sexual well-being [summary adjusted mean difference (adjMD) 5.8, 95% CI 3.4-8.2; three studies] and satisfaction with breasts (summary adjMD 8.1, 95% CI 6.1-10.1; three studies) (moderate SoE for both outcomes). AR was associated with a greater risk of venous thromboembolism (moderate SoE), but IBR was associated with a greater risk of reconstructive failure (moderate SoE) and seroma (low SoE) in long-term follow-up (1.5-4 years). Other outcomes were comparable between groups, or the evidence was insufficient to merit conclusions.

Conclusions

Most evidence regarding IBR versus AR is of low or moderate SoE. AR is probably associated with better sexual well-being and satisfaction with breasts and lower risks of seroma and long-term reconstructive failure but a higher risk of thromboembolic events. New high-quality research is needed to address the important research gaps.

Autologous Fat Grafting as a Stand-alone Method for Immediate Breast Reconstruction After Radical Mastectomy in a Series of 15 Patients

OBJECTIVE

To date, breast reconstruction after mastectomy essentially uses flap- or prosthetic-based surgery. Autologous fat grafting (AFT) largely used in breast conservative surgery is considered an additional technique in breast reconstruction. The aim of this retrospective study was to report our experience of AFT as a stand-alone method for immediate breast reconstruction.

PATIENTS AND METHODS

Fifteen patients requiring a radical mastectomy underwent AFT for immediate reconstruction since 2014. Previous breast irradiation was not a contraindication. Procedures, complications, and cosmetic results were retrospectively analyzed.

RESULTS

Fifteen patients with an average age of 60.5 (43-78) years were included in this retrospective study. They had a body mass index ranging from 19 to 40. Fourteen had a mastectomy for cancer and 1 for prophylaxis. Nine received breast irradiation (7 before surgery and 2 adjuvant). A mean of 3 (2-6) AFT procedures were required to achieve total breast reconstruction. Except for the first transfer, others were performed as outpatient surgeries. Only 2 minor complications (1 hematoma and 1 abscess) not impairing results were reported. The results after a mean follow-up of 26 months were considered by the patients and surgeon as highly satisfactory even in previously irradiated breast, as assessed using a qualitative scoring analysis.

CONCLUSIONS

Autologous fat grafting as a stand-alone method for immediate breast reconstruction after radical mastectomy is a safe procedure with very consistent results even for patients requiring radiation therapy.

Efficacy of da Vinci robot-assisted lymph node surgery than conventional axillary lymph node dissection in breast cancer - A comparative study

BACKGROUND

da Vinci robot-assisted axillary lymph node dissection (dVALND) can be a minimally invasive technique to minimize post-operative complications.

OBJECTIVE

To explore the clinical efficacy of dVALND in breast cancer (BC) patients for mitigating the postoperative complications than conventional ALND.

METHODS

Total 60 female patients with BC were admitted to our hospitals since September 2018, and these patients segregated into two groups of 30 patients each. Modified radical mastectomy for BC was performed to the patients in both groups. In Group 1 (control group), ALND was performed using conventional mode of axillary lymph node surgery. In Group 2 (Test group), the dVALND was performed using da Vinci robot-assisted surgery. Wound healing, aesthetic effect and patient's satisfaction were evaluated after conventional method and dVALND.

RESULTS

Postoperative complications viz., wound infection (1/30 (3.33%), p < 0.05), fat necrosis (3/30 (10%), p < 0.05) and lymphedema of upper limbs (2/30 (6.67%), p < 0.05) were observed in dVALND than conventional surgery. Local recurrence or metastasis was minimized and overall aesthetic effect not observed during follow-up.

CONCLUSION

dVALND improved the overall patient's quality of life by mitigating postoperative complications than ALND.

Effect of surgical complications on outcomes in breast cancer patients treated with mastectomy and immediate reconstruction

BACKGROUND

Operative complications affect recurrence in non-breast malignancies. Rising rates of mastectomy with immediate reconstruction and their increased post-operative complications fuel concerns for poorer outcome in breast cancer (BC). We sought to determine the effect of complications on recurrence in BC patients.

METHODS

A single-institution retrospective review was conducted of incident BC treated with mastectomy and immediate reconstruction. Overall survival and recurrence were compared between patients with complications to those without.

RESULTS

Of 201 patients (350 mastectomies, 86 nipple-sparing), 62 (30.8%) had a surgical complication. Patients with complications were older, but groups were similar for type of reconstruction, tobacco use, hormone receptor status, HER2, lymphovascular invasion, and pathologic stage (all p > 0.05). Twenty-two complications (10.9%) were infection, 5 (2.5%) dehiscence, 14 flap necrosis (7%), 21 hematomas (10.4%), and 8 nipple necroses (9%). Recurrence occurred in 18 (8.9%) patients: 4 local, 2 regional, and 12 distant. After 8.9 years of median follow-up, patients with complications trended towards higher recurrence (hazard ratio (HR) 2.23, log-rank p = 0.08, Cox regression p = 0.05), particularly with nipple necrosis (HR 3.28, log-rank p = 0.09, regression p = 0.06). Patients with other complications had similar recurrence-free survival to those without (all p > 0.05). Higher stage (HR 13.66, log-rank p = 0.03) and adjuvant radiation (HR 2.78, log-rank p = 0.04) cases were more likely to recur. Patients with complications had similar overall survival to those without (log-rank p > 0.05).

CONCLUSION

BC patients with surgical complications do not have lower overall survival. This finding may be due to the improved prognosis compared to non-breast malignancies.

Multi-center investigation of breast reconstruction after mastectomy from Chinese Society of Breast Surgery: A survey based on 31 tertiary hospitals (CSBrS-004)

Objective

Multi-center data on the current status and trends of breast reconstruction after mastectomy in China are lacking. Herein, we conducted a cross-sectional survey to investigate the current clinical practice pattern of postmastectomy breast reconstruction among Chinese female patients with breast cancer.

Methods

A standardized questionnaire used to collect information on breast reconstruction among females diagnosed with breast cancer was distributed by 31 members of the Chinese Society of Breast Surgery between January 1, 2018 and December 31, 2018. Information was collected on tumor characteristics, treatment, mesh application, nipple-areola complex (NAC) preservation, postoperative complications, bilateral reconstruction, patient satisfaction and local recurrence. The overall rate of breast reconstruction was assessed, and the characteristics were compared across patient groups with different reconstruction approaches.

Results

A total of 1,554 patients underwent breast reconstruction after total mastectomy, with a reconstruction rate of 9.6%. Among them, 1,190 were implant-based, and 262 underwent autologous reconstructions, while 102 cases underwent a combination of both. Patients who underwent implant-based reconstruction were younger than those who received autologous reconstruction (40.1±4.6 vs. 45.0±5.9, P=0.004). Compared to patients with autologous reconstruction, mesh application (25.5% vs. 6.5%), NAC preservation (51.8% vs. 40.5%) and reconstruction failure (1.8% vs. 0) were more frequently reported among those with implant-based reconstruction. There was no significant difference in general satisfaction across three reconstruction approaches, though patients with autologous reconstruction reported the highest aesthetic satisfaction among the three groups (P=0.044).

Conclusions

Implant-based breast reconstruction remains the dominant choice among patients, while autologous reconstruction was associated with higher aesthetic satisfaction. Our multi-center investigation based on the findings of the tertiary hospitals of Chinese Society of Breast Surgery may guide a future series of clinical studies on breast reconstruction in China.

Breast Implants for Mammaplasty: An Umbrella Review of Meta-analyses of Multiple Complications

BACKGROUND

The association of breast implants and complications after mammaplasty has been extensively researched. The aim of this study is to summarize all available results in meta-analysis investigating the association between implants and the incidence of various complications.

METHODS

An umbrella review for breast implants and associated complications was performed by searching related reviews from electronic databases including Pubmed, Ovid and CINAHL. We collected and reviewed evidence across meta-analyses of observational and interventional studies of implants and any health outcome. The quality of the reviews was assessed using the AMSTAR tool (A measurement tool to assess systematic reviews).

RESULTS

The research included 92 meta-analyses of 609 studies concerning various areas. Capsular contracture was the most investigated outcome. Radiotherapy, human acellular dermal matrix application, direct-to-implant reconstruction, smooth implant, silicone-filled implant and periareolar incision were significantly associated with higher rates of some of the complications.

CONCLUSIONS

This umbrella review provides surgeons with summarized evidence of the association between the complications and implant-related factors in mammaplasty surgery to help surgeons make informed choices in the future.

Post-mastectomy radiation therapy in breast reconstruction: a patterns of care study of the Korean Radiation Oncology Group

PURPOSE

The details of breast reconstruction and radiation therapy (RT) vary between institutions; therefore, we sought to investigate the practice patterns of radiation oncologists who specialize in breast cancer.

MATERIALS AND METHODS

We identified the practice patterns and inter-hospital variations from a multi-center cohort of women with breast cancer who underwent post-mastectomy RT (PMRT) to the reconstructed breast at 16 institutions between 2015 and 2016. The institutions were requested to contour the target volume and produce RT plans for one representative case with five different clinical scenarios and answer questionnaires which elicited infrastructural information. We assessed the inter-institutional variations in RT in terms of the target, normal organ delineation, and dose-volume histograms.

RESULTS

Three hundred fourteen patients were included; 99% of them underwent immediate reconstruction. The most irradiated material was tissue expander (36.9%) followed by transverse rectus abdominis musculocutaneous flap (23.9%) and silicone implant (12.1%). In prosthetic-based reconstruction with tissue expander, most patients received PMRT following partial deflation. Conventional fractionation and hypofractionation RT were used in 66.6% and 33.4% patients, respectively (commonest: 40.05 Gy in 15 fractions [17.5%]). Furthermore, 15.6% of the patients received boost RT and 53.5% were treated with bolus. Overall, 15 physicians responded to the questionnaires and six submitted their contours and RT plans. There was a significant variability in target delineations and RT plans between physicians, and between clinical scenarios.

CONCLUSION

Adjuvant RT following post-mastectomy reconstruction has become a common practice in Korea. The details vary significantly between institutions, which highlights an urgent need for standard protocol in this clinical setting.

Complications and Patient-reported Outcomes after TRAM and DIEP Flaps: A Systematic Review and Meta-analysis

Supplemental Digital Content is available in the text.

Transverse rectus abdominis myocutaneous (TRAM) and deep inferior epigastric artery perforator (DIEP) flaps are the most common abdominally based breast reconstruction procedures. Each technique has its advantages and disadvantages; however, how morbidity relates to satisfaction is not well-understood. Our aim was to compare complications and patient-reported outcomes following pedicled TRAM (pTRAM), free TRAM (fTRAM), and DIEP flaps to guide flap selection.

Robotic Surgery: A Novel Approach for Breast Surgery and Reconstruction

Supplemental Digital Content is available in the text.

Background:

Breast cancer is the most prevalent cancer and second leading cause of cancer-related deaths in both the US and UK female population, a prominent cause of morbidity and cost to both health services. All surgically fit patients are offered breast reconstruction following the initial surgery, and this is traditionally an open approach: either implant-based or an autologous tissue flap. Both lead to scarring that is difficult to conceal. This paper aims to evaluate the novel minimally invasive technique of robotic-assisted surgery.

Methods:

A systematic review was conducted using Medline (OvidSP) and Embase (OvidSP) to evaluate the current application of robotic-assisted surgery in breast surgery and reconstruction.

Results:

Twenty-one articles were identified and discussed, composing of level 4 and 5 evidence comparing different surgeons' experiences, techniques, and outcomes. To date, the robotic system has been utilized to harvest the latissimus dorsi muscle for use as a tissue flap (total harvest time of 92 minutes), to perform nipple-sparing mastectomy with immediate breast reconstruction (total operation time 85 minutes) and lately to harvest a deep inferior epigastric perforator flap via an intraabdominal approach.

Conclusions:

Robotic-assisted surgery can successfully and reproducibly perform a nipple-sparing mastectomy with breast reconstruction. It can minimize the size of scarring and is superior to the laparoscopic technique, with improved 3-dimensional visualization, dexterity, and range of motion able to guide around the curvature of the breast. The main limiting factors are the lack of the US Food and Drug Administration approval, cost of the robot, and specialized skills required.
