RESUMO
INTRODUCTION: Although nipple-sparing mastectomy (NSM) and immediate breast reconstruction (IBR) have long been praised for excellent cosmetic results and the resultant psychosocial benefits, the feasibility and safety of these procedures in patients older than 60 years have yet to be demonstrated in a large population. METHODS: Patients undergoing NSM with or without IBR at the MedStar Georgetown University Hospital between 1998 and 2017 were included. Patient demographics, surgical intervention, and complication and recurrence events were retrieved from electronic medical records. Primary outcomes were recurrence and complication rates by age groups older and younger than 60 years. RESULTS: There were 673 breasts from 397 patients; 58 (8.6%) older than 60 years and 615 (91.4%) younger than 60 years with mean follow-up of 5.43 (0.12) years. The mean age for those older than 60 was 63.9 (3.3) years, whereas that for those younger than 60 was 43.1 (7.9) years (P < 0.001). The older than 60 group had significantly higher prevalence of diabetes, rates of therapeutic (vs prophylactic) and unilateral (vs bilateral) NSM, and mastectomy weight. However, there were no significant differences by age group in complication rates or increased risk of locoregional or distant recurrence with age. CONCLUSIONS: Based on similar complication profiles in both age groups, we demonstrate safety and feasibility of both NSM and IBR in the aging population. Despite increased age and comorbidity status, appropriately selected older women were able to achieve similar outcomes to younger women undergoing NSM with or without IBR.

BACKGROUND: Mesh infection is one of the most devastating complications after ventral hernia repair. To date, no clear consensus exists on the optimal timing of definitive abdominal wall reconstruction (AWR) after excision of infected mesh. We evaluated outcomes of immediate multistaged AWR in patients with mesh infection. METHODS: We performed a retrospective review of patients with mesh infection who underwent immediate, multistaged AWR, which consisted of exploratory laparotomy with debridement and mesh explantation, followed by definitive AWR during the same admission. Primary outcomes included hernia recurrence and surgical site occurrences, defined as wound dehiscence, surgical site infection, hematoma, and seroma. RESULTS: Forty-seven patients with infected mesh were identified. At mean follow-up of 9.5 months, 5 patients (10.6%) experienced hernia recurrence. Higher body mass index (P = 0.006), bridge repair (P = 0.035), and postoperative surgical site infection (P = 0.005) were associated with hernia recurrence. CONCLUSION: Immediate multistaged AWR is an effective surgical approach in patients with infected mesh.

INTRODUCTION: Nipple-sparing mastectomy (NSM) offers improved, patient-centered outcomes with demonstrated oncologic safety ( Ann Surg Oncol 2020;27:344-351). Indications for NSM continue to expand to patients outside of the traditional eligibility criteria, including those with prior breast-conserving therapy (BCT) with radiotherapy. Currently, limited data exist evaluating both short- and long-term outcomes in patients proceeding to NSM after prior BCT. METHODS: All patients undergoing bilateral NSM in a single institution from 2002 through 2017 with history of prior BCT were included in the final cohort, without exclusions. A retrospective chart review was performed to identify patient demographics, operative details, and complications. Outcomes assessed included early complications (<30 days from NSM), late complications (>30 days), rates of prosthetic failure, unplanned reoperations, and reconstructive failures, as well as oncologic safety. Student t , χ 2 , and Fisher exact tests were used to analyze outcomes of paired (BCT vs non-BCT) breasts within each patient. RESULTS: A total of 17 patients undergoing 34 NSMs were included. Each had a history of BCT and either ipsilateral breast recurrence (64.7%), risk-reducing NSM (23.5%), or a new contralateral primary cancer (11.8%). The cohort had a mean age of 51.1 years. With regard to acute complications (ischemia, infection, nipple-areolar complex or flap ischemia or necrosis, and wound dehiscence), there was no significant difference noted between breasts with prior BCT versus no prior BCT overall (41.2% vs 35.3%, respectively; P = 0.724). Complications occurring after 30 days postoperatively (capsular contracture, contour abnormality, animation deformity, bottoming out, rotation, and rippling) in prior BCT breasts versus no prior BCT had no significant differences overall (58.8% vs 41.2% respectively; P = 0.303). The mean follow-up was 5.5 years, during which no patients had a reported locoregional or distant recurrence in either breast. CONCLUSIONS: No significant differences in early or late complications were identified between breasts in patients undergoing bilateral NSM with a history of unilateral BCT and XRT. In the 5.5 years of follow-up, there were no recurrences, lending support to NSM for management of recurrent disease in addition to National Comprehensive Cancer Network-recommended total mastectomy. We propose that NSM should not be contraindicated in patients exposed to radiation with BCT.

BACKGROUND: Nipple-sparing mastectomy (NSM) offers improved aesthetics without compromising oncologic safety. Subpectoral breast reconstruction has long been standard practice, although prepectoral reconstruction has recently resurged in popularity. Due to this recent paradigm shift, studies comparing long-term outcomes by reconstructive plane are lacking. METHODS: A retrospective review was conducted on consecutive NSMs with implant-based reconstruction in either the prepectoral or subpectoral plane from 2014 to 2018. Patient demographics, implant specifications, and operative details were collected to evaluate primary outcomes of prosthetic failure and unplanned reoperations by reconstructive plane. Secondary outcomes included animation deformity, capsular contracture, rippling, plane change, and minor revisions, including fat grafting. Bivariate and multivariate analyses were performed to assess outcomes. RESULTS: Overall, 405 NSMs were performed on 228 women (subpectoral = 202, prepectoral = 203), with a mean follow-up of 2.1 years (standard deviation 1.1). During the study period (2014-2018), a shift from subpectoral to predominantly prepectoral mastectomies occurred in 2017. Prepectoral reconstructions were more often direct-to-implant (DTI) compared with subpectoral (73.9% vs. 33.2%, p < 0.001). Prepectoral reconstruction demonstrated significantly reduced prosthetic failure (odds ratio [OR] 0.30, 95% confidence interval [CI] 0.14-0.65) and unplanned reoperations (OR 0.43, 95% CI 0.24-0.77) compared with subpectoral reconstruction after controlling for implant characteristics and other possible confounders. Prepectoral patients experienced decreased animation deformity overall (19.7% vs. 0.0%, p < 0.001), with plane changes seen in 10.6% of subpectoral reconstructions for animation deformity correction. Prepectoral patients experienced an increase in rippling (15.3% vs. 6.1%, p = 0.003) without a significant increase in fat grafting (subpectoral = 11.6% vs. prepectoral = 12.3%, p = 0.829). CONCLUSIONS: This single-institution experience compares late complications of prepectoral and subpectoral implant-based reconstruction following NSM. Prepectoral reconstruction can be safely performed with improved understanding of mastectomy planes, readily affords DTI reconstruction, and reduces animation deformity at the expense of rippling.

Understanding the risk factors that contribute to post-mastectomy complications can better inform preoperative discussions. Here, we assess the impact of the 5-Factor Frailty Index Score (mFI-5) in predicting 30-day postoperative complications in patients undergoing mastectomy. A retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) data base was conducted for patients older than 65 undergoing mastectomy between 2010 and 2015. We assessed each patient's Frailty Index Score using the mFI-5. Primary outcomes included wound complications and overall complications. Multivariate logistic and linear regression analyses were used to determine the ability of the mFI-5 to predict postoperative outcomes. A total of 13,783 patients were analyzed. The rate of wound complications was 3.0%, while the rate of overall complications was 6.0%. An mFI-5 score greater than 2 was an independent risk factor for wound complications and overall complications. Overall, patients undergoing mastectomy with an mFI-5 of 2 or greater experienced higher rates of postoperative complications. The mFI-5 is an accessible tool that can be used to risk-stratify patients undergoing mastectomy and can positively contribute to the informed consent and shared decision-making process.

BACKGROUND: The operating microscope is used in many centers for microvascular hepatic arterial reconstruction in living as well as deceased donor liver transplantation in adult and pediatric recipients. To date, a systematic review of the literature examining this topic is lacking. METHODS: This systematic review of the literature was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Three different electronic databases (PubMed, Embase OVID, and Cochrane CENTRAL) were queried. RESULTS: A total of 34 studies were included. The rate of hepatic artery thrombosis (HAT) in noncomparative studies (28) ranged from 0% to 10%, with 8 studies reporting patient deaths resulting from HAT. Within comparative studies, the rate of HAT in patients who underwent arterial reconstruction using the operating microscope ranged from 0% to 5.3%, whereas the rate of HAT in patients who underwent arterial reconstruction using loupe magnification ranged from 0% up to 28.6%, and 2 studies reported patient deaths resulting from HAT. Two comparative studies did not find statistically significant differences between the 2 groups. CONCLUSIONS: Our comprehensive systematic review of the literature seems to suggest that overall, rates of HAT may be lower when the operating microscope is used for hepatic arterial reconstruction in liver transplantation. However, matched comparisons are lacking and surgical teams need to be mindful of the learning curve associated with the use of the operating microscope as compared with loupe magnification, as well as the logistical and time constraints associated with setup of the operating microscope.

Opioid-free anesthesia (OFA) is being implemented in breast surgery due to increased awareness of adverse effects and the national opioid crisis. The objective of this study was to examine the effect of OFA on postoperative pain and postoperative nausea and vomiting (PONV) in mastectomy patients. A single-institution matched-cohort study was conducted from 2014 to 2017 on 48 women undergoing mastectomy, with the majority also undergoing immediate prosthetic-based reconstruction. Patients received either conventional anesthesia (CA) or a novel OFA regimen. Primary outcomes included postoperative pain scores, opioid use, and need for antiemetics that were evaluated both in the PACU and on the hospital floors. No significant differences were found in PACU opioid or antiemetic use between OFA and CA. Pain scores in PACU and on POD0 were not significantly different. There was a significant but modest decrease on POD1 in OFA patients (3.9 vs. 5.1, P = .046). Additionally, patients with higher intraoperative opioid regimens experienced significantly increased PONV (P = .023). This study demonstrated the efficacy of OFA in controlling postoperative pain and nausea compared to a traditional opioid-based regimen. Regardless of intraoperative opioids, patients experienced similar postoperative opioid requirements and PONV with decreased pain scores. Thus, OFA is feasible in mastectomy patients and should be further evaluated in select patients.

BACKGROUND: Cross-sex vascularized composite allotransplantation has been performed in cadaveric facial transplantation and clinical extremity transplantation. Understanding the challenge of appropriate donor-recipient matching, this study sought to characterize the public's perception of cross-sex vascularized composite allotransplantation. METHODS: Participants were surveyed in New York City. Data collected included demographics and willingness to donate vascularized composite allografts (VCAs) of various types. Similar questions were asked in the context of same-sex and cross-sex donation. RESULTS: A total of 101 participants (male: 56.4%; age ≤35 years: 62.4%) were surveyed. The majority expressed willingness to donate to recipients of a different sex (hand: 78.2%, face: 56.4%, penis or uterus: 69.3%, lower limb: 81.2%, abdominal wall: 80.2%, larynx: 81.2%, and solid organs: 85.2%). Among VCAs, willingness to donate facial allografts was significantly different in same-sex versus cross-sex contexts (64.4% vs 56.4%; P = 0.008). Participants were also significantly more likely to donate VCAs to same-sex recipients on behalf of themselves versus loved ones (P < 0.05). There was significantly lower willingness to receive cross-sex versus same-sex facial (P = 0.022) and genital allografts (P = 0.022). Education on the preservation of recipient masculinity or femininity in cross-sex facial transplantation increased participants' willingness to receive a cross-sex face transplant from 56.4% to 71.3% (P = 0.001). CONCLUSIONS: This study highlights the urban public's acceptance of VCA donation or reception regardless of sex mismatch. There is increased willingness to receive a cross-sex face transplant after education, highlighting opportunities for future focused interventions to increase public awareness and ultimately the donor pool.

BACKGROUND: As the demand for nipple-sparing mastectomy (NSM) increases and surgeons expand the eligibility criteria, a subset of patients may become candidates following neoadjuvant chemotherapy (NACT). However, the impact of NACT on postoperative complications remains unclear as the current literature is discordant. METHODS: A single-institution, retrospective chart review was performed on patients undergoing NSM from 1989 to 2017. Patient demographics, surgical intervention, systemic treatment, and complication rates were collected. Primary outcomes were 30-day postoperative complications, including nipple-areolar necrosis, skin flap necrosis, infection, wound dehiscence, hematoma, and seroma. Secondary outcomes included characterization of the timing between chemotherapy and surgical intervention, and the impact on complication rates. Each breast was considered independently for analysis, and breasts undergoing either NACT or primary surgery (PS) were compared. RESULTS: Of the 832 breasts included, 88 (10.6%) received NACT and 744 (89.4%) underwent PS. Baseline complication rates were not significantly different between the NACT group and the PS group (5.7% vs. 10.6%; p = 0.119). When controlling for age, body mass index (BMI), smoking, and prior radiation, NACT was not a predictor of complications. Time from completion of NACT to PS occurred at a median of 40.5 days (interquartile range 31.3-55.3), and decreased intervals were not associated with increased complication rates. CONCLUSIONS: Postoperative complications following NSM in patients completing NACT are comparable with those receiving PS. Patients undergoing NACT do not have a significantly increased risk of necrosis, unintended reoperations, or nipple loss. NACT should not be considered a contraindication for NSM.

PURPOSE: Periorbital injuries are common in face transplantation (FT) candidates. It is therefore essential that the ophthalmologist play a central role in the multidisciplinary treatment of these patients. In this study, the authors perform a comprehensive review of all procedures involving periorbital components, provide an update for the ophthalmology community regarding the current state of the field, and present 2 cases. METHODS: A comprehensive review of the literature for all FT procedures including periorbital components was performed. The authors also present 2 patients who received FT including periorbital components for extensive facial disfigurement. One patient sustained high-energy avulsive ballistic injury and underwent a total face, double jaw, and tongue transplant in 2012. The second patient received a total face, eyelids, ears, and skeletal subunits transplant for extensive facial burns in 2015. RESULTS: Literature review demonstrated that 22 (54%) of the 41 patients undergoing FT received allografts containing periorbital components. Only 14 cases (64%) reported on the presence of ocular and periocular complications. The most common complications consisted of lower eyelid ectropion and lagophthalmos, and nearly all required revisional procedures. Both patients presented with significant periorbital scarring and demonstrated good visual acuity and aesthetic outcomes at postoperative follow up between 6 and 28 months. CONCLUSIONS: Face transplantation can address extensive facial and periorbital disfigurement with satisfactory functional and aesthetic outcomes. The majority of FT performed to date have included periorbital components, and postoperative ocular and periocular complications are common. It is critical for ophthalmologists to play a central role in the care of these patients.

INTRODUCTION: The number of patients who may benefit from evaluation for face transplantation in the United States (US) remains largely unknown. The goal of our study was to better delineate the pool of patients who might benefit from face transplant evaluation based on the characteristics and mechanisms of injury of previously reported face transplant recipients. METHODS: The authors utilized data from the National Electronic Injury Surveillance System-All Injury Program in this study. The US Census Bureau data were used for population estimates. Inclusion and exclusion criteria were determined based on the characteristics of face transplant recipients to date, and the mechanisms of injury they sustained ultimately necessitating face transplantation. Statistical significance was reached if Pâ<0.05. RESULTS: The estimated annual incidence of preventable craniofacial injuries from firearms (44,266-58,299; 31.7% increase), burns (5712-19,433; 240.2% increase), and animal attacks (5355-14,666; 173.9% increase) increased from 2005 to 2014, whereas the estimated annual incidence of craniofacial injuries from machinery (3927-2933; 25.3% decrease) decreased between 2005 and 2014. The authors estimate the annual incidence rate to fall between 32.1 per 100,000 and 58.1 per 100,000 among individuals aged 20 to 64 in the US. CONCLUSION: In this study, the authors estimate the annual incidence rate of individuals aged 20 to 64 in the US who may benefit from face transplant evaluation and believe that this quantification has the potential to initiate actionable discussions regarding geographical and financial factors affecting access to care in this patient population.

BACKGROUND: The aim of this study is to describe a less aggressive approach to management of positive nipple margin following nipple-sparing mastectomy (NSM), allowing for preservation of the nipple-areolar complex (NAC). STUDY DESIGN: A single-institution retrospective chart review was performed for patients undergoing NSM from 1989 to 2017. Positive nipple margin was defined as any residual invasive carcinoma or ductal carcinoma in situ (DCIS) within the additional nipple margin. Management included complete NAC removal, subareolar shave biopsy, or observation alone. Primary outcomes included rates of positive nipple margin and local recurrence. RESULTS: A total of 819 breasts underwent NSM, yielding a total of 32 breasts (3.9%) with positive nipple margin. Management included 11 (34.4%) subareolar shave biopsies, 15 (46.9%) complete NAC excisions, and 5 (15.6%) with observation alone, plus 1 (3.1%) lost to follow-up. Final pathology after subareolar shave biopsy did not reveal any residual disease, and no patients developed NAC necrosis or required NAC removal. Final pathology after NAC excision revealed 3 of 15 with additional disease (1 invasive ductal carcinoma, 2 DCIS). Of the five patients who had no subsequent intervention, tumor pathology was DCIS in all cases. One patient received adjuvant radiation therapy. Mean time to intervention was 3.7 ± 1.9 with mean follow-up of 2.9 years. CONCLUSIONS: Management of positive nipple margin after NSM with subareolar shave biopsy is a safe alternative to preserve the NAC.

The aim of this study is to assess the complication profile and impact on patient-reported quality of life in those undergoing nipple-sparing mastectomy (NSM) with immediate breast reconstruction and subsequent prosthetic reconstruction in patients with prior breast radiation therapy (pRT) vs those receiving adjuvant post-mastectomy radiation therapy (PMRT). An IRB-approved, retrospective analysis was performed from 2002 to 2014 to identify NSM patients that underwent pRT or PMRT. A 22-item Likert scale questionnaire was administered by a third party to register patient-reported quality of life. Forty patients met criteria for outcomes analysis, and 30 patients answered the questionnaire. Mean age was 45.6 years old and mean follow-up was 3.8 years. Complication rates for the PMRT cohort were 61.9% vs 31.6% in the pRT cohort, P = .067, and those requiring operative intervention were PMRT 38.1% vs pRT 5.3%, P = .021. Nipple-areolar complex survival was 100% in the pRT vs 85.7% in the PMRT, P = .233. Breast-related quality of life scores were superior in the pRT group within multiple domains. Patients are more likely to develop complications requiring an operative intervention and have decreased breast-related quality of life when undergoing NSM with PMRT compared to patients undergoing NSM having received pRT.

Clostridium septicum is a rare organism, accounting for approximately 1.3% of clostridial infections and is associated with synchronous colonic malignancy. This case report describes a patient successfully treated for a mycotic aortic aneurysm secondary to C. septicum bacteremia. Subsequent evaluation confirmed a colonic malignancy, prompting early intervention. A systematic literature review revealing a rate of gastrointestinal malignancy in this patient population is 71%, and hematologic malignancy is 3.9%, with the remaining cohort of patients having an unknown source. Infectious involvement of the aorta and associated vascular structures portends a poor prognosis with a 57% mortality rate. Our case and updated review demonstrates the implications of C. septicum vascular seeding and subsequent treatment outcomes.

Reconstructing auricular deformities for bilateral microtia is a demanding challenge especially after failed autologous reconstruction. This case report presents a novel application of virtual surgical planning, computer-assisted design, and intraoperative surgical navigation to preplan and execute placement of custom-tailored silicone auricular prostheses and titanium osseointegrated implants for a bone-anchored hearing aid system in a patient with Treacher Collins syndrome in whom autologous reconstruction had previously failed. Through a collaborative approach between the reconstructive surgeon and anaplastologist, the implementation of advanced digital technologies may offer a superior esthetic and functional outcome to patients with previously failed reconstruction.

BACKGROUND: The purpose of this study was to investigate whether lymphatic reconstitution and regeneration occurs after clinical facial transplantation using indocyanine green lymphography and immunohistochemical markers. METHODS: Allograft skin biopsies at multiple posttransplant time points were stained with Lyve1 lymphatic antibody and other endothelial antibodies. Staining intensity was interpreted on a scale of none, mild, moderate, and strong by 2 investigators and consolidated by a third party for final interpretation. Standardized real-time lymphography was performed at various posttransplant time points to evaluate lymphatic reconstitution and regeneration. RESULTS: Forty-two biopsies were evaluated at 15 different time points from posttransplant days 7 to 420. Strong Lyve1 staining was observed in 52.4%, moderate staining in 14.3%, and weak staining in 33.3% of biopsies. Strong staining was present on days 7, 10, 44, 79, 269, 402, and 420. Three lymphographic studies were conducted at 8.5, 30, and 35 months posttransplant. Initial drainage via distinct lymphatic channels with abrupt dermal splash and lymphostasis was observed at 8.5-month posttransplant. At 30- and 35-month posttransplant, communication of multiple lymphatic channels between donor tissue and recipient tissue was evident with distinct drainage into native recipient cervical lymph nodes. This correlated with ongoing clinical resolution of facial edema and was unaffected by 3 episodes of acute rejection. CONCLUSIONS: These findings support ongoing lymphatic reconstitution between the donor facial allograft and recipient native tissue. Donor lymphatic regeneration begins after facial transplantation and continues long term. This mechanism may be responsible for the temporal and spatial process of lymphatic reconstitution with recipient lymphatic channels.

Clinical face transplantation, only 10 years old, has evolved into a safe and preferred reconstructive option for the most severe facial defects, in which traditional reconstructive methods have yielded poor outcomes. The ability to simultaneously restore facial function and aesthetics has shown to improve patient's quality of life. Its applicability to post-oncologic resection, however, remains guarded given the current international experience with respect to long term outcomes. J. Surg.

BACKGROUND: The purpose of this study was to conduct a systematic review and pooled analysis of vascularized toe-to-hand transfer to determine functional donor site morbidity among different techniques. METHODS: Pubmed MEDLINE, EMBASE, and Cochrane databases search yielded 302 citations, with 56 meeting inclusion criteria. Pooled outcomes and analysis are reported based on donor site morbidity, specific toe transferred, technique used, and foot biomechanical changes. RESULTS: A total of 802 digit transfers (418 isolated great toe transfers, 324 isolated second toe transfers, and 153 toes classified as "other") were included for analysis. Sex was reported in 510 patients (80.2 % men, 19.8% women). The mean patient age was 28.5 ± 8.4 years. Functional impairment analysis found 23.7% (97 digit transfers) experienced gait impairment. Great toe transfer versus second toe transfer versus the "other" group demonstrated morbidity rates of 21.8%, 14.5%, and 23% (P = 0.001), respectively. Donor site reoperative intervention occurred in 11.8% of cases (95 digits): 4.5%, 16.6%, and 16.0% (P < 0.001), respectively. Mean follow-up time was 62.6 months. CONCLUSIONS: Functional foot impairment can occur after various toe transfer procedures due to altered biomechanics of weight distribution and gait. Rigorous biomechanical foot evaluation of this subset of patients is lacking. Great toe transfer appears to have the highest morbidity rate, but lower reoperative intervention as compared to second toe transfer. Preserving ray projection does not prevent biomechanical changes to the foot, but may delay functional impairment leading to favorable functional interpretation by patients and surgeons.

Surgical techniques such as lymphaticovenous anastomosis and vascularized lymph node (VLN) transfer are gaining momentum in the treatment of lymphedema. Although surgeons may be technically capable of performing these complex procedures, understanding the normal physiology of the lymphatic system and the pathophysiology of lymphedema is critical to the patient selection process, determining which specific procedure to perform, considering the specific anatomic location of surgery, and optimization of outcomes. To familiarize the plastic surgeon with the pathophysiological principles of lymphatic surgery for lymphedema, this review focuses on lymphatic anatomy, histology, physiology, disease progression, and staging in the context of lymphaticovenous anastomosis and VLN transfer.
RESUMO
BACKGROUND AND OBJECTIVES: The impact of adjuvant therapy on the surgical outcomes following breast reconstruction is poorly understood. The purpose of this systematic review was to evaluate surgical outcomes following autologous and prosthetic reconstruction in the setting of post-mastectomy radiation therapy (PMRT) and adjuvant chemotherapy. METHODS: A systematic review of the English literature published from 2000 to 2015 in the Pubmed/MEDLINE database was performed to identify all manuscripts reporting outcome of breast reconstruction in patients receiving PMRT and/or adjuvant chemotherapy. RESULTS: Sixty-two manuscripts met the criteria for inclusion. This included 56 manuscripts (5437 patients) evaluating patients treated with PMRT and 11 manuscripts (820 patients) evaluating patients treated with chemotherapy. Pooled analysis of the PMRT cohort revealed significantly higher weighted incidences of re-operation (P < 0.0001), total complications (P < 0.0001), and reconstructive failure (P < 0.0001) in prosthetic reconstruction compared to autologous. There was little evidence to suggest that postoperative chemotherapy is associated with poorer overall outcomes. CONCLUSIONS: PMRT was associated with an increased incidence of adverse events when compared to chemotherapy. There was little evidence to suggest that adverse events following breast reconstruction were related to adjuvant chemotherapy. Manipulating the method and timing of reconstruction may mitigate some of the undesirable outcomes associated with PMRT.
