Choosing breast-conserving therapy or mastectomy and subpectoral implant breast reconstruction: implications for pectoralis major function.

BACKGROUND: An increasing number of women are choosing mastectomy and subpectoral implant (SI) breast reconstruction over breast-conserving therapy (BCT). It is unclear to what extent these procedures differ in their effect on the pectoralis major (PM). The purpose of this study was to assess the impact of choosing BCT or SI breast reconstruction on PM function. METHODS: Ultrasound shear wave elastography images were acquired from the PM fiber regions and surface electromyography obtained activity from six shoulder muscles, while 14 BCT participants, 14 SI participants, and 14 age-matched controls remained at rest or generated submaximal shoulder torques. RESULTS: BCT and SI participants were significantly weaker in shoulder adduction, while BCT participants were also weaker in internal and external rotation (all p ≤ 0.003). PM function was altered following either BCT or SI. In all treatment groups, the clavicular fiber region contributed primarily to flexion, and the sternocostal primarily contributed to adduction. However, healthy participants utilized the clavicular region more during adduction and the sternocostal region more during flexion when compared to BCT or SI participants (all p ≤ 0.049). The still intact clavicular region increased its contributions to flexion torques in SI participants compared to controls (p = 0.016). Finally, BCT and SI participants compensated for changes in PM function using synergistic shoulder musculature. CONCLUSION: Both BCT and SI breast reconstruction result in significant long-term upper extremity strength deficits. Our results suggest changes to the underlying function of the PM and the adoption of unique but inadequate neuromuscular compensation strategies drive these deficits.

Simultaneous Co-surgeon Deep Inferior Epigastric Perforator (DIEP) Flap Breast Reconstructions: Feasibility and Clinical Outcomes.

BACKGROUND: A co-surgeon model is known to be favorable in microvascular breast reconstruction, but simultaneous co-surgeon deep inferior epigastric perforator (DIEP) flap cases have not been well-studied. The authors hypothesize that performing two simultaneous co-surgeon bilateral DIEP flap reconstructions results in non-inferior clinical outcomes and may improve patient access to care. METHODS: A single-institution, retrospective cohort study was performed utilizing record review to identify all cases of co-surgeon free-flap breast reconstructions over a 38-month period. Patients who underwent simultaneous bilateral DIEP flap breast reconstructions with the same two co-surgeons were identified. The control group consisted of subjects who underwent non-simultaneous reconstruction by the same co-surgeons within the same, preceding, or following month of those in the study group. Primary outcome variables were 90-day postoperative complications, while secondary outcomes were operating time, ischemia time, and length of stay. Descriptive statistics, univariate and multivariable regression analyses were performed. RESULTS: Overall, 137 subjects were identified and 64 met the inclusion criteria (n = 28 study, n = 36 control). There were no statistically significant differences between groups in body mass index, radiation, trainee experience, flap perforator number, immediate/delayed reconstruction, or length of stay. There were also no statistically significant differences in complications, including flap loss, anastomosis revision, take-back to the operating room, or re-admission. Operative time was longer in the simultaneous DIEP group (540.5 vs. 443.5 min, p < 0.01), but ischemia time was shorter in the simultaneous group (64.0 vs. 80.5 min, p < 0.01). CONCLUSIONS: A simultaneous co-surgeon approach to bilateral DIEP flap reconstruction may improve access to care and does not result in a higher complication rate compared with non-simultaneous bilateral DIEP flaps.

A Multi-institutional Analysis of a Textbook Outcome Among Patients Undergoing Microvascular Breast Reconstruction.

BACKGROUND: Individual outcomes may not accurately reflect the quality of perioperative care. Textbook outcomes (TOs) are composite metrics that provide a comprehensive evaluation of hospital performance and surgical quality. This study aimed to investigate the prevalence and predictors of TOs in a multi-institutional cohort of patients who underwent breast reconstruction with deep inferior epigastric artery perforator flaps. METHODS: For autologous reconstruction, a TO was previously defined as a procedure without intraoperative complications, reoperation, infection requiring intravenous antibiotics, readmission, mortality, systemic complications, operative duration ≤12 hours for bilateral and ≤10 hours for unilateral/stacked reconstruction, and length of stay (LOS) ≤5 days. We investigated associations between patient-level factors and achieving a TO using multivariable regression analysis. RESULTS: Of 1000 patients, most (73.2%) met a TO. The most common reasons for deviation from a TO were reoperation (9.6%), prolonged operative time (9.5%), and prolonged LOS (9.2%). On univariate analysis, tobacco use, obesity, widowed/divorced marital status, and contralateral prophylactic mastectomy or bilateral reconstruction were associated with a lower likelihood of TOs (P < 0.05). After adjustment, bilateral prophylactic mastectomy (odds ratio [OR], 5.71; P = 0.029) and hormonal therapy (OR, 1.53; P = 0.050) were associated with a higher likelihood of TOs; higher body mass index (OR, 0.91; P = <0.001) was associated with a lower likelihood. CONCLUSION: Approximately 30% of patients did not achieve a TO, and the likelihood of achieving a TO was influenced by patient and procedural factors. Future studies should investigate how this metric may be used to evaluate patient and hospital-level performance to improve the quality of care in reconstructive surgery.

The Impact of Timing of Delayed Autologous Breast Reconstruction following Postmastectomy Radiation Therapy on Postoperative Morbidity.

BACKGROUND: The ideal time to perform reconstruction after the completion of postmastectomy radiation therapy (PMRT) in patients with locally advanced breast cancer is currently unknown. We evaluate the association between the timing of delayed autologous breast reconstruction following PMRT and postoperative complications. METHODS: Patients who underwent mastectomy, PMRT, and then delayed autologous breast reconstruction from 2009 to 2016 were identified from the Truven Health MarketScan Research Databases. Timing of reconstruction following PMRT was grouped 0-3, 3-6, 6-12, 12-24, and after 24 months. Multivariable models were used to assess associations between timing of reconstruction following PMRT and key measures of morbidity. RESULTS: A total of 1,039 patients met inclusion criteria. The rate of any complications for the analytic cohort was 39.4%, including 13.3% of patients who experienced wound complications and 11.3% of patients requiring additional flaps. Unadjusted rates of complications increased from 23.4% between 0 and 3 months to 49.4% between 3 and 6 months and decreased thereafter. Need for additional flaps was highest within 3 to 6 months (14.0%). Multivariate analysis revealed higher rates of any complications when reconstruction was performed between 3 and 6 months (odds ratio [OR]: 3.04, p < 0.001), 6 and 12 months (OR: 2.66, p < 0.001), or 12 and 24 months (OR: 2.13, p = 0.001) after PMRT. No difference in complications were noted in reconstructions performed after 24 months compared with those performed before 3 months (p > 0.05). However, rates of wound complications were least likely in reconstructions after 24 months (OR: 0.34, p = 0.035). CONCLUSION: These findings suggest plastic surgeons may consider performing autologous breast reconstruction early for select patients, before 3 months following PMRT without increasing postoperative morbidity.

Assessing shoulder muscle stretch reflexes following breast cancer treatment and postmastectomy breast reconstruction.

Muscle stiffness is altered following postmastectomy breast reconstruction and breast cancer treatment. The exact mechanisms underlying these alterations are unknown; however, muscle stretch reflexes may play a role. This work examined short- (SLR) and long-latency (LLR) shoulder muscle stretch reflexes in breast cancer survivors. Forty-nine patients who had undergone postmastectomy breast reconstruction, 17 who had undergone chemoradiation, and 18 healthy, age-matched controls were enrolled. Muscle activity was recorded from the clavicular and sternocostal regions of the pectoralis major and anterior, middle, and posterior deltoids during vertical ab/adduction or horizontal flex/extension perturbations while participants maintained minimal torques. SLR and LLR were quantified for each muscle. Our major finding was that following postmastectomy breast reconstruction, SLR and LLR are impaired in the clavicular region of the pectoralis major. Individuals who had chemoradiation had impaired stretch reflexes in the clavicular and sternocostal region of the pectoralis major, anterior, middle, and posterior deltoid. These findings indicate that breast cancer treatments alter the regulation of shoulder muscle stretch reflexes and may be associated with surgical or nonsurgical damage to the pectoral fascia, muscle spindles, and/or sensory Ia afferents.NEW & NOTEWORTHY Shoulder muscle stretch reflexes may be impacted following postmastectomy breast reconstruction and chemoradiation. Here, we examined short- and long-latency shoulder muscle stretch reflexes in two experiments following common breast reconstruction procedures and chemoradiation. We show impairments in pectoralis major stretch reflexes following postmastectomy breast reconstruction and pectoralis major and deltoid muscle stretch reflexes following chemoradiation. These findings indicate that breast cancer treatments alter the regulation of shoulder muscle stretch reflexes.

A Prospective Evaluation of the Quality of Life and Mental Health Implications of Mastectomy Alone on Women in sub-Saharan Africa.

OBJECTIVE: Assess quality of life and mental health implications of mastectomy for breast cancer on sub-Saharan African women. BACKGROUND: Mortality rates amongst women diagnosed with breast cancer in sub-Saharan Africa (SSA) are high, with disparities in survival relative to women in high income countries partly attributed to advanced disease at presentation. Fears of the sequelae of mastectomy are a prominent reason for presentation delays. There is a critical need to better understand the effects of mastectomy on women in SSA to inform preoperative counseling and education for women with breast cancer. METHODS: Women with breast cancer in Ghana and Ethiopia undergoing mastectomy were followed prospectively. Breast related quality-of-life and mental health measures were evaluated preoperatively, 3 and 6 months postoperatively, using BREAST-Q, PHQ-9, and GAD-7. Bivariate and logistic regression analyses evaluated changes in these measures for the total cohort and between sites. RESULTS: A total of 133 women from Ghana and Ethiopia were recruited. The majority of women presented with unilateral disease (99%) and underwent unilateral mastectomy (98%) with axillary lymph node dissection. Radiation was more common in Ghana ( P <0.001). Across most BREAST-Q subscales, women from both countries reported significantly decreased scores at 3 months postoperative. At 6 months, the combined cohort reported decreased scores for breast satisfaction (mean difference, -3.4). Women in both countries reported similar improvements in anxiety and depression scores postoperatively. CONCLUSIONS: Women from Ghana and Ethiopia who underwent mastectomy experienced a decline in breast-related body image while also experiencing decreased levels of depression and anxiety.

Textbook outcomes in DIEP flap breast reconstruction: a Delphi study to establish consensus.

PURPOSE: Composite measures, like textbook outcomes, may be superior to individual metrics when assessing hospital performance and quality of care. This study utilized a Delphi process to define a textbook outcome in DIEP flap breast reconstruction. METHODS: A two-round Delphi survey defined: (1) A textbook outcome, (2) Exclusion criteria for a study population, and (3) Respondent opinion regarding textbook outcomes. An a priori threshold of ≥ 70% agreement among respondents established consensus among the tested statements. RESULTS: Out of 85 invitees, 48 responded in the first round and 41 in the second. A textbook outcome was defined as one that meets the following within 90 days: (1) No intraoperative complications, (2) Operative duration ≤ 12 h for bilateral and ≤ 10 h for unilateral/stacked reconstruction, (3) No post-surgical complications requiring re-operation, (4) No surgical site infection requiring IV antibiotics, (5) No readmission, (6) No mortality, (7) No systemic complications, and (8) Length of stay < 5 days. Exclusion criteria for medical and surgical characteristics (e.g., BMI > 40, HgbA1c > 7) and case-volume cut-offs for providers (≥ 21) and institutions (≥ 44) were defined. Most agreed that textbook outcomes should be defined for complex plastic surgery procedures (75%) and utilized to gauge hospital performance for microsurgical breast reconstruction (77%). CONCLUSION: This Delphi study identified (1) Key elements of a textbook outcome for DIEP flap breast reconstruction, (2) Exclusion criteria for future studies, and (3) Characterized surgeon opinions regarding the utility of textbook outcomes in serving as quality metric for breast reconstruction care.

Perceived financial decline related to breast reconstruction following mastectomy in a diverse population-based cohort.

BACKGROUND: Despite mandated insurance coverage for breast reconstruction following mastectomy, health care costs are increasingly passed on to women through cost-sharing arrangements and high-deductible health plans. In this population-based study, the authors assessed perceived financial and employment declines related to breast reconstruction following mastectomy. METHODS: Women with early-stage breast cancer (stages 0-II) diagnosed between July 2013 and May 2015 who underwent mastectomy were identified through the Surveillance, Epidemiology, and End Results registries of Georgia and Los Angeles and were surveyed. Primary outcome measures included patients' appraisal of their financial and employment status after cancer treatment. Multivariable models evaluated the association between breast reconstruction and primary outcomes. RESULTS: Among 883 patients with breast cancer who underwent mastectomy, 44.2% did not undergo breast reconstruction, and 55.8% underwent reconstruction. Overall, 21.9% of the cohort reported being worse off financially since their diagnosis (25.8% with reconstruction vs 16.6% without reconstruction; P = .002). Women who underwent reconstruction reported higher out-of-pocket medical expenses (32.1% vs 15.6% with expenses greater than $5000; P < .001). Reconstruction was independently associated with a perceived decline in financial status (odds ratio, 1.92; 95% confidence interval, 1.15-3.22; P = .013). Among women who were employed at the time of their diagnosis, there was no association between reconstruction and a perceived decline in employment status (P = .927). CONCLUSIONS: In this diverse cohort of women who underwent mastectomy, those who elected to undergo reconstruction experienced higher out-of-pocket medical expenses and self-reported financial decline. Patients, providers, and policymakers should be aware of the potential financial implications related to reconstruction despite mandatory insurance coverage.

Financial Toxicity in Breast Reconstruction: A National Survey of Women Who have Undergone Breast Reconstruction After Mastectomy.

BACKGROUND: Despite awareness regarding financial toxicity in breast cancer care, little is known about the financial strain associated with breast reconstruction. This study aims to describe financial toxicity and identify factors independently associated with financial toxicity for women pursuing post-mastectomy breast reconstruction. METHODS: A 33-item electronic survey was distributed to members of the Love Research Army. Women over 18 years of age and at least 1 year after post-mastectomy breast reconstruction were invited to participate. The primary outcome of interest was self-reported financial toxicity due to breast reconstruction, while secondary outcomes of interest were patient-reported out-of-pocket expenses and impact of financial toxicity on surgical decision making. RESULTS: In total, 922 women were included (mean age 58.6 years, standard deviation 10.3 years); 216 women (23.8%) reported financial toxicity from reconstruction. These women had significantly greater out-of-pocket medical expenses. When compared with women who did not experience financial toxicity, those who did were more likely to have debt due to reconstruction (50.9% vs. 3.2%, p < 0.001). Younger age, lower annual household income, greater out-of-pocket expenses, and a postoperative major complication were independently associated with an increased risk for financial toxicity. If faced with the same decision, women experiencing financial toxicity were more likely to decide against reconstruction (p < 0.001) compared with women not experiencing financial toxicity. CONCLUSIONS: Nearly one in four women experienced financial toxicity from breast reconstruction. Women who reported higher levels of financial toxicity were more likely to change their decisions about surgery. Identified factors predictive of financial toxicity could guide preoperative discussions to inform decision making that mitigates undesired financial decline.

Determinants of telemedicine adoption among financially distressed patients with cancer during the COVID-19 pandemic: insights from a nationwide study.

PURPOSE: Telemedicine use during the COVID-19 pandemic among financially distressed patients with cancer, with respect to the determinants of adoption and patterns of utilization, has yet to be delineated. We sought to systematically characterize telemedicine utilization in financially distressed patients with cancer during the COVID-19 pandemic. METHODS: We conducted a cross-sectional analysis of nationwide survey data assessing telemedicine use in patients with cancer during the COVID-19 pandemic collected by Patient Advocate Foundation (PAF) in December 2020. Patients were characterized as financially distressed by self-reporting limited financial resources to manage out-of-pocket costs, psychological distress, and/or adaptive coping behaviors. Primary study outcome was telemedicine utilization during the pandemic. Secondary outcomes were telemedicine utilization volume and modality preferences. Multivariable and Poisson regression analyses were used to identify factors associated with telemedicine use. RESULTS: A convenience sample of 627 patients with cancer responded to the PAF survey. Telemedicine adoption during the pandemic was reported by 67% of patients, with most (63%) preferring video visits. Younger age (19-35 age compared to ≥ 75 age) (OR, 6.07; 95% CI, 1.47-25.1) and more comorbidities (≥ 3 comorbidities compared to cancer only) (OR, 1.79; 95% CI, 1.13-2.65) were factors associated with telemedicine adoption. Younger age (19-35 years) (incidence rate ratios [IRR], 1.78; 95% CI, 24-115%) and higher comorbidities (≥ 3) (IRR; 1.36; 95% CI, 20-55%) were factors associated with higher utilization volume. As area deprivation index increased by 10 units, the number of visits decreased by 3% (IRR 1.03, 95% CI, 1.03-1.05). CONCLUSIONS: The rapid adoption of telemedicine may exacerbate existing inequities, particularly among vulnerable financially distressed patients with cancer. Policy-level interventions are needed for the equitable and efficient provision of this service.

The Global Macroeconomic Burden of Breast Cancer: Implications for Oncologic Surgery.

OBJECTIVE: In this study, we quantified the global macroeconomic burden of breast cancer to underscore the critical importance of improving access to oncologic surgical care internationally. SUMMARY BACKGROUND DATA: Breast cancer mortality in many low and middle-income countries (LMICs) is dramatically higher than in high-income countries. Prior to identifying solutions, however, it is important to first define the burden of disease. METHODS: Data from the Institute of Health Metrics and Evaluation (2005-2015) were used to assess epidemiologic trends for 194, middle, and low-income countries. Economic burden defined by Welfare Loss (WL) was calculated by measuring disability-adjusted-life-years lost to breast cancer alongside the dollar equivalent of a value of statistical life year and as a function of each country's gross domestic product (GDP). RESULTS: Annual mortality rates among breast cancer patients were significantly greater in LMICs in South Asia (3.06 per 100 women) and Sub-Saharan Africa (2.76 per 100 women), compared with high-income countries like the United States (1.69 per 100 women). From 2005-2015, mortality in South Asia increased by 8.20% and decreased by 6.45% in Sub-Saharan Africa; mortality rates in 2015 were observed as 27.9 per 100,000 in South Asia and 18.61 per 100,000 in Sub-Saharan Africa. Countries in South Asia demonstrated the greatest rise in WL due to breast cancer, from 0.05% to 0.08% of GDP. CONCLUSIONS: The burden of disease and economic impact of breast cancer is intensifying in LMICs. Global efforts to improve access to surgical care for women with breast cancer could reduce mortality and mitigate the social and financial impact of this disease in LMICs.

Persistent Disparities in Postmastectomy Breast Reconstruction and Strategies for Mitigation.

For many women, breast reconstruction is an essential component of the breast cancer care continuum after mastectomy. Despite postmastectomy breast reconstruction now being a standard of care, numerous studies over the past decade have documented persistent racial disparities in breast reconstruction rates, physician referral patterns, and patient knowledge of their reconstructive options. These disparities have disproportionately impacted women of color-most specifically, African American women. Recent data have revealed racial differences in patient comorbidities, informed decision-making satisfaction, and clinical outcomes after breast reconstruction. Explicitly, African American women have significantly more risk factors for complications and less baseline knowledge regarding reconstructive options than white women. With a recent heightened attention focused on social determinants of health, studies designed to improve these racial differences have demonstrated promising results through educational outreach to underserved communities, implementation of tailored legislation promoting inclusion, diversity, and equity, and encouragement of additional recruitment of ethnically underrepresented-in-medicine surgeons. This study uses a targeted review of the literature to provide a summary of racial disparities in breast reconstruction for African American women, with our perspective on opportunities for improvement.

Hospital Variations in Clinical Complications and Patient-reported Outcomes at 2 Years After Immediate Breast Reconstruction.

OBJECTIVE: Our objectives were to investigate case-mix adjusted hospital variations in 2-year clinical and patient-reported outcomes following immediate breast reconstruction. BACKGROUND: Over the past few decades, variations in medical practice have been viewed as opportunities to promote best practices and high-value care. METHODS: The Mastectomy Reconstruction Outcomes Consortium Study is an National Cancer Institute-funded longitudinal, prospective cohort study assessing clinical and patient-reported outcomes of immediate breast reconstruction after mastectomy at 11 leading medical centers. Case-mix adjusted comparisons were performed using generalized linear mixed-effects models to assess variation across the centers in any complication, major complications, satisfaction with outcome, and satisfaction with breast. RESULTS: Among 2252 women in the analytic cohort, 1605 (71.3%) underwent implant-based and 647 (28.7%) underwent autologous breast reconstruction. There were significant differences in the sociodemographic and clinical characteristics, and distribution of procedure types at the different Mastectomy Reconstruction Outcomes Consortium Study centers. After case-mix adjustments, hospital variations in the rates of any and major postoperative complications were observed. Medical center odds ratios for major complication ranged from 0.58 to 2.13, compared with the average major complication rate across centers. There were also meaningful differences in satisfaction with outcome (from the lowest to highest of -2.79-2.62) and in satisfaction with breast (-2.82-2.07) compared with the average values. CONCLUSIONS: Two-year postoperative complications varied widely between hospitals following post-mastectomy breast reconstruction. These variations represent an important opportunity to improve care through dissemination of best practices and highlight the limitations of extrapolating single-institution level data and the ongoing challenges of studying hospital-based outcomes for this patient population.

The influence of reconstruction choice and inclusion of radiation therapy on functional shoulder biomechanics in women undergoing mastectomy for breast cancer.

PURPOSE: The functional implications of reconstructing the breast mound with a latissimus dorsi (LD) flap or placing an implant under the pectoralis major (PM) muscle is complicated by potential comorbidities from disinserting these muscles and adjuvant radiotherapy. We utilized novel robot-assisted measures of shoulder stiffness and strength to dissociate how breast reconstruction choice and inclusion of radiation therapy impact shoulder morbidity in post-mastectomy reconstruction patients. METHODS: Shoulder strength and stiffness were collected from 10 irradiated LD flap breast reconstruction patients, 14 two-stage subpectoral implant reconstruction patients (subpectoral), and 10 irradiated deep inferior epigastric perforator (DIEP) flap patients an average of 659 days post-reconstruction. Univariate ANOVAs examined surgical group differences in strength and stiffness. RESULTS: There were main effects of surgical group on vertical adduction, vertical abduction, and internal rotation strength. The LD flap group was significantly weaker than the subpectoral group in all measures and significantly weaker than the DIEP group during vertical adduction. There was also a main effect of surgical group on vertical adduction stiffness, where the LD group exhibited significantly reduced stiffness while producing vertical adduction torque. No significant differences between the subpectoral and DIEP groups existed for any measure of shoulder strength or stiffness. CONCLUSIONS: Disinsertion of the LD, not the disinsertion of the PM or radiotherapy, contributes to strength deficits following LD flap breast reconstructions. The combined disinsertion of the PM and LD compromises shoulder stability in the vertical plane. Shoulder function should be a focal point of the surgical decision-making process and postsurgical care.

Pathology Evaluation of Reduction Mammaplasty Specimens and Subsequent Diagnosis of Malignant Breast Disease: A Claims-Based Analysis.

BACKGROUND: This study aimed to measure the use of pathology evaluation of breast specimens among patients undergoing reduction mammaplasty and assess rates of new diagnoses of breast disease and associated cost. METHODS: We analyzed the Truven MarketScan Databases from 2009 to 2015 to identify adult female patients undergoing reduction mammaplasty for macromastia. We recorded patient age, rates of obtaining pathology evaluation, new diagnoses of benign or malignant breast disease after pathology evaluation, and total cost for the surgery encounter. RESULTS: Among 17,738 macromastia patients undergoing reduction mammaplasty, 91.3% (n = 16,193) received pathology evaluation. Pathology evaluation rates were clinically similar across age groups <70 years (90.8-92.1%) and slightly lower for patients ≥70 (85.0%). Among 6987 patients less than 40 years who received pathology evaluation, 0.06% (n = 4) were subsequently diagnosed with malignant breast disease within 3 months, compared to 0.23% in the entire cohort (n = 37/16,193). Pathology claims resulted in an added $307 (SD 251) on average for the breast reduction surgery encounters. CONCLUSIONS: Breast tissue after reduction mammaplasty is routinely submitted for pathology evaluation, without consideration of age-based risk for breast cancer. Routine pathology evaluation of breast tissue in patients in lower risk age groups (less than 40 years) required an additional $536,000 on average to detect a single occult breast cancer compared to an added $85,600 to detect a new malignancy in patients 40 years and older. Clinicians and policy makers should consider whether routine pathology evaluation of breast tissue should be individualized based on risk factors for breast cancer.

Radiation-Induced Skin Changes after Postmastectomy Radiation Therapy: A Pilot Study on Indicators for Timing of Delayed Breast Reconstruction.

BACKGROUND: Delayed autologous breast reconstruction is commonly recommended in patients requiring postmastectomy radiation. This study examines gross and histologic changes in the breast skin of patients who have undergone postmastectomy radiation to help determine when radiation-induced skin changes begin to stabilize. METHODS: A prospective pilot study was conducted on eight patients with invasive breast cancer who required mastectomy and radiotherapy. At the time of mastectomy and 2, 4, 6, 8, and 12 months after completion of radiotherapy, a punch biopsy was taken from the radiated mastectomy skin of each patient. Serial standardized photographs were taken before and after radiotherapy to evaluate the degree of hyperpigmentation and graded by three blinded plastic surgeons. Skin biopsies were processed for histologic assessment of inflammation, elastin organization, and vascularity. RESULTS: Grading of patient photographs revealed an increase in hyperpigmentation after radiotherapy compared with baseline with a gradual improvement over time. SMAD3 immunostaining demonstrated a trend toward an increase in inflammation over 12 months. The elastin distribution within samples showed an increase in fiber disorganization, thickening, and clumping, with no improvement throughout the study period. The average number of vessels per high powered field decreased steadily through the duration of the study. CONCLUSION: Histologic changes in dermal inflammation, elastin organization, and vascularity do not appear to correspond with the gradual improvement of hyperpigmentation, resulting from postmastectomy radiation. These histologic changes persist beyond the 12 month observation period and will require clinical correlation to determine the potential impact on postoperative outcomes.

Autologous fat grafting to lumpectomy defects: complications, imaging, and biopsy rates.

BACKGROUND: Autologous fat grafting is emerging as a promising reconstructive technique after breast conservation therapy (BCT). Recent evidence suggests that autologous fat grafting does not increase the risk of cancer recurrence; however, women may still be subject to unnecessary biopsies secondary to suspicious radiologic findings. The purpose of this study was to assess surgical complications and biopsy rates in these patients. METHODS: We retrospectively reviewed the records of women who underwent autologous fat grafting after BCT at a single institution over a 6-y period. Independent variables included demographic and operative details. Outcome variables included complications, and incidence of palpable masses and/or suspicious breast imaging findings requiring biopsy. Descriptive statistics were generated. RESULTS: Between June 2008 and February 2015, 37 women aged 41 to 74 y (mean 54.4 y) underwent a total of 56 fat grafting sessions for correction of contour deformities after BCT. The mean number of fat grafting procedures was 1.5 (range 1-4) per breast. Follow-up ranged from 1 to 99 mo (mean 29.5 mo). Imaging data were available for 31 (83.7%) breasts after autologous fat grafting. Biopsy was recommended in four cases after suspicious imaging findings or palpable masses (10.8%), with benign pathology in all cases. There was one incidence of a local wound infection. No other local or systemic complications were noted. CONCLUSIONS: Our study demonstrated a risk of unnecessary biopsies after autologous fat grafting. Complication rates were low, and it appears to be a safe reconstructive option for the correction of contour deformities after BCT.

An Evaluation of the Choice for Contralateral Prophylactic Mastectomy and Patient Concerns About Recurrence in a Reconstructed Cohort.

BACKGROUND: Rising contralateral prophylactic mastectomy rates are a subject of national concern. This study assessed (1) factors critical to patients when deciding on contralateral prophylactic mastectomy and (2) patients' quality of life related to concerns about recurrence after unilateral or bilateral breast reconstruction. METHODS: Patients with stage 0 to III breast cancer who underwent unilateral mastectomy or contralateral prophylactic mastectomy and breast reconstruction at a single institution between 2000 and 2012 were identified. Demographic and clinical data were extracted by chart review. Women's fears about breast cancer recurrence were assessed using the Concerns About Recurrence Scale, and motivational factors for contralateral prophylactic mastectomy were identified using the Decisions for Contralateral Prophylactic Mastectomy Survey. RESULTS: Survey responses were received from 157 patients (59%) who underwent unilateral reconstruction and 109 (41%) who underwent bilateral reconstruction. The top 3 reasons for choosing contralateral prophylactic mastectomy were (1) decreasing the risk of contralateral breast disease (97%), (2) peace of mind (96%), and (3) improved survival (93%). Women who chose contralateral prophylactic mastectomy reported significantly greater overall fear and worry compared with the unilateral group, specifically, greater fears of dying and worries about adequately fulfilling roles of daily life (P < 0.05). CONCLUSIONS: Despite no proven survival benefit, women chose contralateral prophylactic mastectomy primarily to optimize oncologic outcomes. Among breast reconstruction patients, women who underwent contralateral prophylactic mastectomy had greater anxiety and overall fear of breast cancer recurrence compared with those who chose unilateral mastectomy. These findings are important to consider when counseling women contemplating contralateral prophylactic mastectomy.

Simplifying Arterial Coupling in Microsurgery-A Preclinical Assessment of an Everter Device to Aid with Arterial Anastomosis.

BACKGROUND: A novel arterial everter device was engineered to simplify microvascular coupling of arteries by reliably securing the stiff, muscular wall of arteries over coupler pins. We compare microvascular coupling with the everter device to manual suturing for arterial anastomoses in a live large animal model. MATERIALS AND METHODS: In this preliminary study, bilateral external femoral arteries of five male swine were exposed and sharply divided. Arteries were anastomosed using either interrupted sutures (n = 5) or the everter device and Synovis Coupler (n = 5). The efficiency in engaging coupler pins, the time taken to perform the anastomosis, and vessel patency immediately post-op and at 1-week postanastomosis were evaluated. Vessel wall injury and luminal stenosis were compared between groups using histomorphometric analyses. RESULTS: On an average, 80% of coupler pins engaged the vessel walls after a single pass of the everter. The average time to perform the anastomosis was significantly less when using the everter/coupler compared with manual suturing (6:35 minutes versus 25:09 minutes, p < 0.001). Immediately post-op, 100% patency was observed in both groups. At 1 week post-op, four of five (80%) of coupled arteries and all five (100%) of hand-sewn arteries were patent. The degree of arterial wall injury, neointimal formation, and luminal stenosis for patent arteries were similar between groups. CONCLUSIONS: Successful arterial anastomoses using the everter device with the Synovis Coupler was easier and significantly more efficient when compared with a standard hand-sewn technique. Both techniques had acceptable patency rates and similar effects on the vessel wall and intima.
