RESUMEN

OBJECTIVE: To implement the BREASTChoice decision tool into the electronic health record and evaluate its effectiveness. BACKGROUND: BREASTChoice, is a multilevel decision tool that: 1) educates patients about breast reconstruction; 2) estimates personalized risk of complications; 3) clarifies patient preferences; and 4) informs clinicians about patients' risk and preferences. METHODS: A multisite randomized controlled trial enrolled adult women with stage 0-III breast malignancy undergoing mastectomy. Participants were randomized to BREASTChoice or a control website. A survey assessed knowledge, preferences, decisional conflict, shared decision-making, preferred treatment, and usability. We conducted intent-to-treat (ITT), per-protocol (PP) analyses (those randomized to BREASTChoice who accessed the tool), and stratified analyses. RESULTS: 23/25 eligible clinicians enrolled. 369/761 (48%) contacted patients enrolled and were randomized. Patients' average age was 51 years; 15% were older than 65. BREASTChoice participants had higher knowledge than control participants (ITT: mean 70.6 vs. 67.4, P=0.08; PP: mean 71.4 vs. 67.4, P=0.03), especially when stratified by site (ITT: P=0.04, PP: P=0.01), age (ITT: P=0.04, PP: P=0.02), and race (ITT: P=0.04, PP: P=0.01). BREASTChoice did not improve decisional conflict, match between preferences and treatment, or shared decision-making. In PP analyses, fewer high-risk patients using BREASTChoice chose reconstruction. BREASTChoice had high usability. CONCLUSIONS: BREASTChoice is a novel decision tool incorporating risk prediction, patient education, and clinician engagement. Patients using BREASTChoice had higher knowledge; older adults and those from racially minoritized backgrounds especially benefitted. There was no impact on other decision outcomes. Future studies should overcome implementation barriers and specifically examine decision outcomes among high-risk patients.

RESUMEN

Implanted medical devices are widely used across various medical specialties for numerous applications, ranging from cardiovascular supports to orthopedic prostheses and cosmetic enhancements. However, recent observations have raised concerns about the potential of these implants to induce malignancies in the tissues surrounding them. There have been several case reports documenting the occurrence of cancers adjacent to these devices, prompting a closer examination of their safety. This review delves into the epidemiology, clinical presentations, pathological findings, and hypothesized mechanisms of carcinogenesis related to implanted devices. It also explores how the surgical domain and the intrinsic properties and biocompatibility of the implants might influence the development of these rare but serious malignancies. Understanding these associations is crucial for assessing the risks associated with the use of medical implants, and for developing strategies to mitigate potential adverse outcomes.

RESUMEN

BACKGROUND: Direct-to-implant (DTI) breast reconstruction after mastectomy has gained increasing popularity. While concerns over ischemic complications related to tension on the mastectomy flap persist, newer techniques and technologies have enhanced safety of this technique. OBJECTIVES: To compare clinical and patient-reported outcomes of DTI and two-stage tissue expander (TE) reconstruction. METHODS: A prospective cohort design was utilized to compare the incidence of reconstructive failure among patients undergoing DTI and TE reconstruction via unadjusted bivariate and adjusted multivariable logistic regression analyses. Secondary clinical outcomes of interest included specific complications requiring intervention (infection, seroma, hematoma, mastectomy flap necrosis, incisional dehiscence, device exposure) and time to final drain removal. Patient-reported outcomes (PROs) via BREAST-Q were also compared. RESULTS: A total of 134 patients (257 breasts) underwent DTI reconstruction and 222 patients (405 breasts) received TEs. DTI patients were significantly younger with lower BMIs, less diabetes, hypertension, and smoking, and smaller breast sizes, and underwent more nipple-sparing mastectomies with prepectoral reconstructions. Rates of any complication (18% DTI vs 24% TE, p=0.047), reconstructive failure (5.1% vs 12%, p=0.004), and seroma (3.9% vs 11%, p<0.001) were significantly lower in the DTI cohort on unadjusted analyses; however, there were no significant differences in adjusted regressions. Patient-reported satisfaction with breasts, psychosocial well-being, and sexual well-being were more substantively improved with DTI reconstruction. CONCLUSIONS: Prepectoral DTI reconstruction is a viable option for post-mastectomy reconstruction in carefully selected patients, with no significant increase in reconstructive failure or other complications.

RESUMEN

BACKGROUND: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare malignancy originating from the periprosthetic capsule of a textured, most often macrotextured, breast implant. Identified in women whose indications for breast implants can be either aesthetic or reconstructive, the genomic underpinnings of this disease are only beginning to be elucidated. OBJECTIVES: The aim of this study was to evaluate the exomes, and in some cases the entire genome, of patients with BIA-ALCL. Specific attention was paid to copy number alterations, chromosomal translocations, and other genomic abnormalities overrepresented in patients with BIA-ALCL. METHODS: Whole-exome sequencing was performed on 6 patients, and whole-genome sequencing on 3 patients, with the Illumina NovaSeq 6000 sequencer. Data were analyzed with the Illumina DRAGEN Bio-IT Platform and the ChromoSeq pipeline. The Pathseq Genome Analysis Toolkit pipeline was used to detect the presence of microbial genomes in the sequenced samples. RESULTS: Two cases with STAT3 mutations and 2 cases with NRAS mutations were noted. A critically deleted 7-Mb region was identified at the 11q22.3 region of chromosome 11, and multiple nonrecurrent chromosomal rearrangements were identified by whole-genome sequencing. Recurrent gene-level rearrangements, however, were not identified. None of the samples showed evidence of potential microbial pathogens. CONCLUSIONS: Although no recurrent mutations were identified, this study identified mutations in genes not previously reported with BIA-ALCL or other forms of ALCL. Furthermore, not previously reported with BIA-ALCL, 11q22.3 deletions were consistent across whole-genome sequencing cases and present in some exomes.

RESUMEN

BACKGROUND AND AIMS: Insulin resistance is a key factor in the pathogenesis of nonalcoholic fatty liver disease (NAFLD). We evaluated the importance of subcutaneous abdominal adipose tissue (SAAT) inflammation and both plasma and SAAT-derived exosomes in regulating insulin sensitivity in people with obesity and NAFLD. METHODS: Adipose tissue inflammation (macrophage and T-cell content and expression of proinflammatory cytokines), liver and whole-body insulin sensitivity (assessed using a hyperinsulinemic-euglycemic clamp and glucose tracer infusion), and 24-hour serial plasma cytokine concentrations were evaluated in 3 groups stratified by adiposity and intrahepatic triglyceride (IHTG) content: (1) lean with normal IHTG content (LEAN; N = 14); (2) obese with normal IHTG content (OB-NL; N = 28); and (3) obese with NAFLD (OB-NAFLD; N = 28). The effect of plasma and SAAT-derived exosomes on insulin-stimulated Akt phosphorylation in human skeletal muscle myotubes and mouse primary hepatocytes was assessed in a subset of participants. RESULTS: Proinflammatory macrophages, proinflammatory CD4 and CD8 T-cell populations, and gene expression of several cytokines in SAAT were greater in the OB-NAFLD than the OB-NL and LEAN groups. However, with the exception of PAI-1, which was greater in the OB-NAFLD than the LEAN and OB-NL groups, 24-hour plasma cytokine concentration areas-under-the-curve were not different between groups. The percentage of proinflammatory macrophages and plasma PAI-1 concentration areas-under-the-curve were inversely correlated with both hepatic and whole-body insulin sensitivity. Compared with exosomes from OB-NL participants, plasma and SAAT-derived exosomes from the OB-NAFLD group decreased insulin signaling in myotubes and hepatocytes. CONCLUSIONS: Systemic insulin resistance in people with obesity and NAFLD is associated with increased plasma PAI-1 concentrations and both plasma and SAAT-derived exosomes.

RESUMEN

PURPOSE: Breast cancer is diagnosed at a median age of 62 years in the USA. At the same time, mortality rates for breast cancer continue to decrease, falling by 40% from 1989 to 2016. In the coming decades, the number of elderly patients with breast cancer, potentially seeking reconstruction, is expected to increase. METHODS: A retrospective chart review of 309 patients, aged 60 years or older, undergoing immediate or delayed breast reconstruction, was conducted. Patient characteristics, clinical information and major complications requiring reoperation were evaluated. Multivariate analyses identified factors contributing to complications such as BMI, comorbidities, smoking status, history of previous breast conservation therapy (BCT), total expander volume, radiotherapy, and chemotherapy. RESULTS: 26.7% of patients had at least one complication requiring reoperation, and 6.9% of patients suffered reconstructive failure. Logistic regression analysis of all patients (n = 309) found a statistically significant relationship between major complication and history of ipsilateral BCT (p = 0.026) and adjuvant chemotherapy (p = 0.005). Logistic regression analysis in patients undergoing tissue expander (TE) reconstruction (n = 215) showed that major complications were related to BMI over 35 kg/m2 (p = 0.04), history of ipsilateral BCT (p = 0.048), and adjuvant chemotherapy (p = 0.033). CONCLUSION: Breast reconstruction in women over 60 years old was not independently associated with higher major complication rates in our series.

RESUMEN

BACKGROUND: A greater proportion of patients with surgical risk factors are undergoing immediate breast reconstruction after mastectomy, resulting in the need for better risk prediction to inform decisions about the procedure. The objective of this study was to leverage clinical data to restructure a previously developed risk model to predict serious infectious and noninfectious wound complications after mastectomy alone and mastectomy plus immediate reconstruction for use during a surgical consultation. METHODS: The study established a cohort of women age 21 years or older treated with mastectomy from 1 July 2010 to 31 December 2015 using electronic health records from two hospitals. Serious infectious and non-infectious wound complications, defined as surgical-site infection, dehiscence, tissue necrosis, fat necrosis requiring hospitalization, or surgical treatment, were identified within 180 days after surgery. Risk factors for serious wound complications were determined using modified Poisson regression, with discrimination and calibration measures. Bootstrap validation was performed to correct for overfitting. RESULTS: Among 2159 mastectomy procedures, 1410 (65.3%) included immediate implant or flap reconstruction. Serious wound complications were identified after 237 (16.8%) mastectomy-plus-reconstruction and 30 (4.0%) mastectomy-only procedures. Independent risk factors for serious wound complications included immediate reconstruction, bilateral mastectomy, higher body mass index, depression, and smoking. The optimism-corrected C statistic of the risk prediction model was 0.735. CONCLUSIONS: Immediate reconstruction, bilateral mastectomy, obesity, depression, and smoking were significant risk factors for serious wound complications in this population of women undergoing mastectomy. Our risk prediction model can be used to counsel women before surgery concerning their individual risk of serious wound complications after mastectomy.

RESUMEN

Despite advances in medical therapy, the foundation of breast cancer treatment is surgery. The landscape of operative intervention for breast cancer has shifted toward less invasive techniques, resulting in improved cosmesis and lower morbidity while maintaining oncologic integrity. In this article, we review the body of literature contributing to landmark advances in mastectomy for the treatment of breast cancer.

RESUMEN

BACKGROUND: En bloc capsulectomy has recently increased in prominence as a potential surgical therapy for patients with breast implant illness (BII). However, this procedure has chiefly been recommended for treating breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). OBJECTIVES: This study aimed to review the current literature and evaluate the public understanding of treatment options for BII via social media to characterize any potential communication disconnect between clinicians and patients. METHODS: An electronic literature review was performed to identify all available publications mentioning evidence-based support for en bloc capsulectomy as treatment for BII and BIA-ALCL. Twitter social media posts referencing BII or BIA-ALCL were analyzed from 2010 to 2019. Author identity and any mention of surgical treatment were assessed. RESULTS: A total of 115 publications on the subject of BII and 315 articles on BIA-ALCL were identified. En bloc resection was recommended only for patients with a diagnosis of BIA-ALCL. A total of 6419 tweets referencing BII and 6431 tweets referencing BIA-ALCL were identified. Tweets referencing BIA-ALCL were significantly more likely to be authored by physicians (25.9% vs 5.3%, P < 0.001), and tweets referencing BII were significantly more likely to mention any surgical treatment (7.8% vs 1.9%, P < 0.001) and en bloc capsulectomy (1.4% vs 0.3%, P < 0.001). CONCLUSIONS: This study demonstrates that a communication disconnect exists between the scientific literature and social media regarding treatment options for BII and BIA-ALCL. Physicians should be aware of these potential misconceptions to empathetically address patient concerns in a patient-centered manner.

RESUMEN

OBJECTIVE: To evaluate a web-based breast reconstruction decision aid, BREASTChoice. SUMMARY AND BACKGROUND DATA: Although postmastectomy breast reconstruction can restore quality of life and body image, its morbidity remains substantial. Many patients lack adequate knowledge to make informed choices. Decisions are often discordant with patients' preferences. METHODS: Adult women with stages 0-III breast cancer considering postmastectomy breast reconstruction with no previous reconstruction were randomized to BREASTChoice or enhanced usual care (EUC). RESULTS: Three hundred seventy-six patients were screened; 120 of 172 (69.8%) eligible patients enrolled. Mean age = 50.7 years (range 25-77). Most were Non-Hispanic White (86.3%) and had a college degree (64.3%). Controlling for health literacy and provider seen, BREASTChoice users had higher knowledge than those in EUC (84.6% vs. 58.2% questions correct; P < 0.001). Those using BREASTChoice were more likely to know that reconstruction typically requires more than 1 surgery, delayed reconstruction lowers one's risk, and implants may need replacement over time (all ps < 0.002). BREASTChoice compared to EUC participants also felt more confident understanding reconstruction information (P = 0.009). There were no differences between groups in decisional conflict, decision process quality, shared decision-making, quality of life, or preferences (all ps > 0.05). There were no differences in consultation length between BREASTChoice and EUC groups (mean = 29.7 vs. 30.0 minutes; P > 0.05). BREASTChoice had high usability (mean score = 6.3/7). Participants completed BREASTChoice in about 27 minutes. CONCLUSIONS: BREASTChoice can improve breast reconstruction decision quality by improving patients' knowledge and providing them with personalized risk estimates. More research is needed to facilitate point-of-care decision support and examine BREASTChoice's impact on patients' decisions over time.

RESUMEN

PURPOSE: We explored the impact of the relative volume of a tumor versus the entire breast on outcomes in patients undergoing breast conservation therapy (BCT) versus mastectomy and reconstruction (M + R). We hypothesized that there would be a threshold tumor:breast ratio (TBR) below which patient-reported outcomes (PRO) would favor BCT and above which would favor M + R. METHODS: We conducted a prospective cohort study of patients with ductal carcinoma in situ (DCIS) or invasive breast cancers undergoing BCT or M + R. A prerequisite for inclusion, analysis of tumor and breast volumes was conducted from three-dimensional magnetic resonance imaging reconstructions to calculate the TBR. Three-dimensional photography was utilized to calculate pre- and postoperative volumes and assess symmetry. Oncologic, surgical, and patient-reported outcome data were obtained from relevant BREAST-Q modules administered pre- and postoperatively. RESULTS: The BCT cohort had significantly smaller tumor volumes (p = 0.001) and lower TBRs (p = 0.001) than patients undergoing M + R overall. The M + R group, however, comprised a broader range of TBRs, characterized at lower values by patients opting for contralateral prophylactic mastectomy. Postoperative satisfaction with breasts, psychosocial, and sexual well-being scores were significantly higher in the BCT cohort, while physical well-being significantly favored the M + R cohort 480.2 ± 286.3 and 453.1 ± 392.7 days later, respectively. CONCLUSIONS: Relative to BCT, M + R was used to manage a broad range of TBRs. The relative importance of oncologic and surgical risk reduction, symmetry, and number of procedures can vary considerably and may limit the utility of TBR as a guide for deciding between BCT and M + R. Clinical Trial StatementThis study was registered with clinicaltrials.gov as "A Prospective Trial to Assess Tumor:Breast Ratio and Patient Satisfaction Following Lumpectomy Versus Mastectomy With Reconstruction", Identifier: NCT02216136.

RESUMEN

Breast implant-associated anaplastic large T-cell lymphoma (BIA-ALCL) was first recognized by the World Health Organization in 2016. The total number of cases worldwide continues to increase, with >800 cases confirmed through a combination of Food and Drug Administration data, verified reports, and registries. To date, 33 deaths have been reported. Typical presentation includes a late seroma containing monoclonal T cells that are CD30 positive and anaplastic lymphoma kinase negative. We present a review of the current literature and report on 3 cases of BIA-ALCL at our institution, which serve to illustrate our approach to diagnosis and management of this disease. In 2 cases, the diagnosis of BIA-ALCL was not initially confirmed due to an incomplete workup but was recognized upon explantation. The seroma fluid was sent for flow cytometry. Initially, the cells were reported as morphologically suspicious for malignancy with phenotypically normal T cells based on standard CD3+ T-cell gating. Subsequent cytology specimens were reported as consistent with recurrent adenocarcinoma. However, upon regating of flow-cytometry data, a population of CD30+, CD3- T cells was noted and the diagnosis of BIA-ALCL was confirmed by immunohistochemical stains of the excised breast capsule specimen. Given the increasing incidence of this disease, as plastic surgeons we must stay informed to order the correct workup to avoid misdiagnosis and be prepared to appropriately refer affected patients to centers with multidisciplinary teams experienced in the management of BIA-ALCL.

RESUMEN

BACKGROUND: Staphylococcus epidermidis and Pseudomonas aeruginosa are the most common causes of Gram-positive and Gram-negative breast implant-associated infection. Little is known about how these bacteria infect breast implants as a function of implant surface characteristics and timing of infection. OBJECTIVES: The aim of this work was to establish a mouse model for studying the impact of various conditions on breast implant infection. METHODS: Ninety-one mice were implanted with 273 breast implant shells and infected with S. epidermidis or P. aeruginosa. Smooth, microtextured, and macrotextured breast implant shells were implanted in each mouse. Bacterial inoculation occurred during implantation or 1 day later. Implants were retrieved 1 or 7 days later. Explanted breast implant shells were sonicated, cultured, and colony-forming units determined or analyzed with scanning electron microscopy. RESULTS: P. aeruginosa could be detected on all device surfaces at 1- and 7- days post infection (dpi), when mice were implanted and infected concurrently or when they were infected 1- day after implantation. However, P. aeruginosa infection was more robust on implant shells retrieved at 7 dpi and particularly on the macrotextured devices that were infected 1 day post implantation. S. epidermidis was mostly cleared from implants when mice were infected and implanted concurrently. Other the other hand, S. epidermidis could be detected on all device surfaces at 1 dpi and 2 days post implantation. However, S. epidermdis infection was suppressed by 7 dpi and 8 days post implantation. CONCLUSIONS: S. epidermidis required higher inoculating doses to cause infection and was cleared within 7 days. P. aeruginosa infected at lower inoculating doses, with robust biofilms noted 7 days later.

RESUMEN

BACKGROUND: Staphylococcus epidermidis is a primary cause of breast implant-associated infection. S epidermidis possesses several virulence factors that enable it to bind both abiotic surfaces and host factors to form a biofilm. In addition S epidermidis colocalizes with matrix proteins coating explanted human breast implants. OBJECTIVES: The authors sought to identify matrix proteins that S epidermidis may exploit to infect various breast implant surfaces in vitro. METHODS: A combination of in vitro assays was used to characterize S epidermidis strains isolated from human breast implants to gain a better understanding of how these bacteria colonize breast implant surfaces. These included determining the (1) minimum inhibitory and bactericidal concentrations for irrigation solutions commonly used to prevent breast implant contamination; (2) expression and carriage of polysaccharide intercellular adhesin and serine-aspartate repeat proteins, which bind fibrinogen (SdrG) and collagen (SdrF), respectively; and (3) biofilm formation on varying implant surface characteristics, in different growth media, and supplemented with fibrinogen and Types I and III collagen. Scanning electron microscopy and immunofluorescence staining analyses were performed to corroborate findings from these assays. RESULTS: Textured breast implant surfaces support greater bacterial biofilm formation at baseline, and the addition of collagen significantly increases biomass on all surfaces tested. We found that S epidermidis isolated from breast implants all encoded SdrF. Consistent with this finding, these strains had a clear affinity for Type I collagen, forming dense, highly structured biofilms in its presence. CONCLUSIONS: The authors found that S epidermidis may utilize SdrF to interact with Type I collagen to form biofilm on breast implant surfaces.

RESUMEN

BACKGROUND: Despite growing demand for breast reconstruction, financial disincentives to perform breast reconstruction in patients with government-sponsored insurance plans may lead to longer wait times and decreased access to care. We identify the variation in reimbursement for implant and autologous reconstruction as a step toward understanding these financial implications, to develop safeguards to minimize effects on access to care. METHODS: Billing data were collected over a 10-year period for patients undergoing implant-based (19357) or free-flap (19364) breast reconstruction. Patients were placed into cohorts according to insurance type-Medicare, Medicaid, or private insurance, and these were directly compared. RESULTS: A total of 2691 women underwent breast reconstruction between 2003 and 2013; 71.2% had private insurance, 13.3% had Medicaid, and 14.49% had Medicare. For implant-based reconstructions, the average reimbursement of total charges was 16.3% for Medicaid, 28.3% for Medicare, and 67.2% for private insurance. For autologous reconstruction, average reimbursement was 12.37% for Medicaid, 22.9% for Medicare, and 35.35% for private insurance. Hourly reimbursement estimates for Medicaid patients undergoing autologous reconstruction were lowest. The highest hourly reimbursement estimate was for privately insured patients undergoing implant-based reconstruction. Over time, reimbursement for autologous reconstruction has declined significantly for all payor types, whereas implant-based reimbursement disparities are narrowing. CONCLUSIONS: We found that wide variations in reimbursement for breast reconstruction procedures exist and may preclude some surgeons from offering certain reconstructive options to a subset of patients. Understanding these discrepancies is a key first step in minimizing a potential care delivery disparity for this patient population.

RESUMEN

Nonsurgical vulvovaginal rejuvenation (NVR) is growing in popularity as a treatment for restoration of youthful female genitalia. Numerous radiofrequency (RF) and laser devices have entered the market claiming improvement in vaginal laxity and genitourinary syndrome of menopause. There is a paucity of evidence existing concerning the effectiveness of these devices for both pre- and postmenopausal women with laxity and/or atrophy at the histologic and clinical level. Therefore, the goal of this review is to scrutinize the peer-reviewed data on NVR with RF and laser devices, identify gaps in existing literature, and propose opportunities for further investigation.

RESUMEN

Mastopexy and mastopexy-augmentation are aesthetic breast surgeries that seek to create youthful, beautiful appearing breasts. Age, hormonal changes, or weight loss can lead to alterations that require addressing the skin envelope and breast parenchyma. Many surgical approaches have been described including periareolar, vertical, and Wise pattern techniques, but most modern mastopexies include manipulation of the breast parenchyma to improve the longevity of breast ptosis correction. Mesh support of the ptotic breast is an extension of this paradigm shift and seeks to restore the lost strength of the support structures of the breast. Despite initial controversy, single stage mastopexy-augmentation has been demonstrated to be a safe option for appropriately selected and informed patients who desire both correction of shape and volume. Revisions may still be necessary based on patient and surgeon goals for correction. Evolving technologies will likely continue to enhance the ability of aesthetic plastic surgeons to provide pleasing, durable correction of breast ptosis.

RESUMEN

BACKGROUND: Sexual health issues can be characterized by vaginal laxity (VL), sexual distress, and sexual dysfunction. The epidemiology of these issues in plastic surgery patients, and especially breast cancer survivors, remains poorly understood. OBJECTIVES: To prospectively assess sexual health issues in a plastic surgery patient population with and without breast cancer. METHODS: A prospective cohort study was created in our practice from June to August 2017 with administration of a survey including the vaginal laxity questionnaire (VLQ), female sexual distress scale-revised (FSDS-R), and female sexual function index (FSFI). Multivariate logistic regression identified the controlled effect of patient variables on development of sexual health issues. RESULTS: Of 291 patients solicited, 239 completed the survey (37.7% breast cancer survivors vs 62.3% without). Prevalence of VL was nearly 1 in 6 women. Of these, 46.0% met criteria for sexual distress (FSDS-R ≥ 11.0) and 64.8% had sexual dysfunction (FSFI ≤ 26.5). Breast cancer survivors exhibited significantly greater overall sexual dysfunction (P < 0.001) and greater dysfunction within all FSFI domains of desire, arousal, lubrication, orgasm, satisfaction, and pain (all P < 0.02). On multivariate regression, number of vaginal deliveries predicted development of VL (OR 1.87, P < 0.001), presence of VL predicted sexual distress (OR 3.01, P = 0.007), while history of breast cancer predicted sexual dysfunction (OR 1.87, P < 0.05). CONCLUSIONS: Sexual health issues are prevalent amongst plastic surgery patients. Aesthetic practices can improve patients' quality of life by focusing on these areas. Potential therapeutic options to address sexual health issues should consider addressing vaginal laxity.

RESUMEN

BACKGROUND: Implant-based breast reconstruction (IBR) after nipple-sparing mastectomies (NSM) can have complications that require explantation of a tissue expander or permanent prosthesis. When complications occur, preservation of the nipple-areola complex (NAC) remains critical to ensure aesthetic breast reconstruction. To date, there are minimal data on outcomes for patients experiencing unplanned explantations in IBR after NSM. OBJECTIVES: To evaluate final reconstructive outcomes for NSM patients who undergo IBR and have an unplanned explanation and to separately analyze the outcome of the NAC aesthetic subunit. METHODS: We analyzed a prospectively maintained database of NSM patients undergoing IBR reconstruction at a single institution to identify patients who had complications resulting in unplanned explanation. Demographics, covariates, and reconstructive outcomes, including salvage with IBR or autologous flaps, were assessed. Final outcomes of the NAC were also evaluated. RESULTS: A total of 213 patients underwent 382 NSM with IBR with either direct-to-implant (DTI) or tissue expander/implant (TE/I) reconstructions. The complication rate was 15.2% (N = 58) and 33 (8.6%) unplanned explantations occurred: 23 (69.8%) of whom ultimately completed reconstruction with either IBR (30.4%) or autologous flaps (69.6%). NACs were preserved in 62.5% of breasts with unplanned explantations. Only 8 NACs were lost in the entire cohort (2.1%). CONCLUSIONS: Following unplanned explantations in IBR after NSM, salvage can be performed with either IBR or autologous flaps. However, the majority of salvage procedures in IBR after NSM will be with autologous flaps that bring in healthy soft tissue to restore location specific defects caused by complications. The NAC can ultimately be preserved as an aesthetic subunit in most patients despite the occurrence of initial complications.

RESUMEN

PURPOSE: Tamoxifen therapy is integral in the treatment of patients with hormone receptor-positive breast cancer. However, there is an association between tamoxifen and thromboembolic events. Flap and systemic thromboembolic events have devastating consequences in microvascular breast reconstruction. Currently, there are conflicting data on the association between tamoxifen therapy and thromboembolic complications for patients undergoing microvascular breast reconstruction. The objective of this study is to determine if perioperative tamoxifen therapy modifies the risk of complications and thromboembolic events for patients with breast cancer undergoing microvascular breast reconstruction. METHODS: A comprehensive literature search was performed across six databases from January 2003 to February 2016. Pooled estimates and relative risk (RR) were calculated using a random-effects model, confounding was examined with meta-regression, and risk of bias was evaluated. Primary outcomes were thrombotic flap complications and total flap loss. Study quality was assessed using Downs and Black criteria. RESULTS: Of 95 studies reviewed, 4 studies comprising 1700 patients and 2245 procedures were included for analysis. Compared to non-recipients, patients on tamoxifen were at increased risk of developing thrombotic flap complications (pooled RR 1.5; 95% CI 1.14-1.98) and total flap loss (pooled RR 3.35; 95% CI 0.95-11.91). There was no significant heterogeneity present in either outcome and no evidence of publication bias. CONCLUSIONS: Perioperative tamoxifen therapy may increase the risk of thrombotic flap complications and flap loss for patients with breast cancer undergoing microvascular reconstruction. These findings further the ability of providers to make evidence-based recommendations in the perioperative management of patients with breast cancer.
