Geographic variation in breast reconstruction surgery after mastectomy for females with breast cancer in Alberta, Canada.

BACKGROUND: Breast cancer is the most common cancer affecting females in Canada, and about half of females with breast cancer are treated with mastectomy. We sought to evaluate geographic variation in breast reconstruction surgery in Alberta, Canada. METHODS: Using linked population-based administrative databases, we extracted data on all Alberta females aged 18 years and older who were diagnosed with breast cancer and treated with mastectomy during 2004-2017. Analyses included regression modelling of odds of reconstruction at 1 year and a spatial scan to identify geographic clusters of lower numbers of reconstruction. RESULTS: A total of 16 198 females diagnosed with breast cancer were treated with a mastectomy, and 1932 (11.9%) had reconstruction within 1 year postmastectomy. Those with reconstruction were more likely to be younger (adjusted odds ratio [OR] 16.7, 95% confidence interval [CI] 13.7-20.3; aged 21-44 yr v. ≥ 65 yr) and were less likely to be from lower-income neighbourhoods. They were more likely to have at least 1 comorbidity and were more likely to have advanced stages of cancer and to require chemotherapy (adjusted OR 0.55, 95% CI 0.47-0.65) or radiotherapy after mastectomy (adjusted OR 0.59, 95% CI 0.39-0.87) than females without reconstruction. We identified rural northern and southeastern clusters with frequencies of reconstruction that were 69.6% and 41.6% of what was expected, respectively. CONCLUSION: We found an overall postmastectomy rate of breast reconstruction of 11.9%, and we identified geographic variation. Predictors of reconstruction in Alberta were similar to those previously described in the literature, specifically with patients in rural communities having lower rates of reconstruction than their urban counterparts. These results suggest that further interventions are required to identify the specific barriers to reconstruction within rural communities and to create strategies to ensure equitable access to all residents.

Return of the Flap; The Empire State Mandate: A Multi-decade Multi-institutional Analysis of the 2010 New York State Legislature's Impact on Postmastectomy Immediate Flap-Based Reconstruction.

PURPOSE: Immediate postmastectomy breast reconstruction plays an integral role in patient care because of its psychosocial benefits. New York State (NYS) passed the 2010 Breast Cancer Provider Discussion Law with the aim of increasing patient awareness of reconstructive options through mandating plastic surgery referral at the time of cancer diagnosis. Short-term analysis of the years surrounding implementation suggests the law increased access to reconstruction, especially for certain minority groups. However, given the continued presence of disparities in access to autologous reconstruction, we aimed to investigate the longitudinal effects of the bill on access to autologous reconstruction along various sociodemographic cohorts. METHODS: Retrospective review identified demographic, socioeconomic, and clinical data for patients undergoing mastectomy with immediate reconstruction at Weill Cornell Medicine and Columbia University Irving Medical Center from 2002 to 2019. Primary outcome was receiving implant or autologous-based reconstruction. Subgroup analysis was based on sociodemographic factors. Multivariate logistic regression identified predictors of autologous reconstruction. Interrupted time series modeling analyzed differences in reconstructive trends for subgroups before and after the 2011 implementation of the NYS law. RESULTS: We included 3178 patients; 2418 (76.1%) and 760 (23.9%) patients underwent implant and autologous-based reconstruction, respectively. Multivariate analysis indicated that race, Hispanic status, and income were not predictors of autologous reconstruction. Interrupted time series showed that with each year leading up to 2011 implementation, patients were 19% less likely to receive autologous-based reconstruction. Following implementation, there was a 34% increase in the odds of receiving autologous-based reconstruction with each passing year. Following implementation, Asian American and Pacific Islander patients experienced a 55% greater increase in the rate of flap reconstruction than White patients. Following implementation, the highest-income quartile experienced a 26% greater increase in the rate of autologous-based reconstruction compared with the lowest-income quartile. After implementation, Hispanic patients experienced a 30% greater decrease in the rate of autologous-based reconstruction compared with non-Hispanic patients. CONCLUSIONS: Our data indicate the long-term efficacy of the NYS Breast Cancer Provider Discussion Law in increasing access to autologous-based reconstruction, especially for certain minority groups. These findings underscore the importance of this bill and encourage its adoption into other states.

Racial Disparities in the Cost of Unplanned Hospitalizations after Breast Reconstruction.

BACKGROUND: Given the national attention to disparities in health care, understanding variation provided to minorities becomes increasingly important. This study will examine the effect of race on the rate and cost of unplanned hospitalizations after breast reconstruction procedures. METHODS: The authors performed an analysis comparing patients undergoing implant-based and autologous breast reconstruction in the Healthcare Cost and Utilization Project. The authors evaluated the rate of unplanned hospitalizations and associated expenditures among patients of different races. Multivariable analyses were performed to determine the association among race and readmissions and health care expenditures. RESULTS: The cohort included 17,042 patients. The rate of an unplanned visit was 5%. The rates of readmissions among black patients (6%) and Hispanic patients (7%) in this study are higher compared with white patients (5%). However, after controlling for patient-level characteristics, race was not an independent predictor of an unplanned visit. In our expenditure model, black patients [adjusted cost ratio, 1.35 (95% CI, 1.11 to 1.66)] and Hispanic patients [adjusted cost ratio, 1.34 (95% CI, 1.08 to 1.65)] experienced greater cost for their readmission compared with white patients. CONCLUSIONS: Although race is not an independent predictor of an unplanned hospital visit after surgery, racial minorities bear a higher cost burden after controlling for insurance status, further stimulating health care disparities. Adjusted payment models may be a strategy to reduce disparities in surgical care. In addition, direct and indirect measures of disparities should be used when examining health care disparities to identify consequences of inequities more robustly.

Oncological Safety of Autologous Fat Grafting in Breast Reconstruction after Mastectomy for cancer: A case-control study.

OBJECTIVE: The use of autologous fat grafting in the context of breast reconstruction is still a matter of controversy. The objective of this study was to compare the local relapse rate in women who had a fat grafting session in the context of breast reconstruction after breast cancer management, to those who had breast reconstruction without fat grafting. METHODS: We performed a retrospective, monocentric, case-control study from January 2007 to December 2017 in our hospital. The cases included women who underwent breast reconstruction with autologous fat grafting and controls, undergoing breast reconstruction without fat grafting. We compared survival and local recurrence between the two groups. RESULTS: 412 women were included: 109 (26.5%) in the lipofilling group and 303 women (73.5%) in the "no lipofilling" group. In the overall study population, lipofilling did not appear to be a predictive factor for recurrence, HR = 1.39 [0.63 - 3.06], p = 0.41; or a predictive factor for overall survival, HR = 0.84 [0.23 - 3.02], p = 0.79, or for distant metastases, HR = 1.10 [0.43 - 2.79], p = 0.84. In contrast, in the subgroup of women treated for invasive cancer, the multivariate analysis showed that lipofilling in this context was an independent predictive factor for local recurrence (HR= 5.06 [1.97 - 10.6], p = 0.04). CONCLUSION: we found an increased risk of local recurrence after lipofilling in women who were managed for invasive breast cancer. This suggests that special consideration should be given to women who have had invasive breast cancer before lipofilling.

Effect of health care disparities on procedure selection of autologous breast reconstruction in Florida.

INTRODUCTION: Disparities in access to reconstructive surgery after breast cancer have been reported. We aim to evaluate demographic and socioeconomic factors influencing type of autologous breast reconstruction in Florida. METHODS: We queried the Florida Inpatient Discharge Dataset to evaluate disparities in type of autologous breast reconstructive surgery between January 1, 2013, and September 30, 2017. Patients 18 years of age or older were included. Women younger than 65 years old on Medicare were excluded. Patients were categorized into three groups according to type of autologous reconstruction: latissimus dorsi pedicled flap (pedicled flap), free flap, or pedicled flap with implant (combined flap). Demographic and socioeconomic variables were evaluated. 𝜒2 and Mann-Whitney tests were used to estimate statistical significance. A multivariate logistic regression was performed to find independent associations. RESULTS: Our results showed higher odds of reconstruction with free flap in Hispanic patients (odds ratio (OR), 1.66; 95% CI, 1.32-2.09; P < 0.0001) and patients with comorbidities (OR, 1.45; 95% CI, 1.23-1.71; P < 0.0001). However, patients treated in Central and South Florida were less likely to undergo free flap than combined and pedicled flap reconstructions compared with those treated in North Florida (P < 0.05). Patients insured by Medicaid and Medicare were less likely to undergo free flap than combined or pedicled flap reconstruction compared to patients with private insurance (P < 0.05). CONCLUSIONS: Our study identified that race, region, insurance, and comorbidity are factors associated with type of autologous breast reconstruction in Florida.

Representation of African American Patients in Social Media for Breast Reconstruction.

BACKGROUND: Social media use by plastic surgeons may contribute to the overall increase in breast reconstruction in the United States. However, recent data show a concerning decrease in breast reconstruction in African American women. The purpose of this study was to analyze the inclusion of African American women in social media posts for breast reconstruction, with the premise that this may be a possible contributing factor to decreasing rates of breast reconstruction in this population. METHODS: Data from several social media platforms were obtained manually on December 1, 2019. Each image was analyzed using the Fitzpatrick scale as a guide. RESULTS: A total of 2580 photographs were included that met the authors' criteria. Only 172 photographs (6.7 percent) were nonwhite. This study surveyed 543 surgeons, 5 percent of whom were nonwhite. The analysis of the results from the random sample of the top plastic surgery social media influencers showed that only 22 (5 percent) of the photographs uploaded were nonwhite patients. Furthermore, 30 percent of surgeons did not have any photographs of nonwhite patients uploaded. CONCLUSIONS: Numerous factors can contribute to the disparity between the growing trend of white patients seeking reconstructive surgery compared to the decreasing trend of African American patients, one of which may be the disparity in their representation in social media, particularly among common platforms and social media influencers. This study highlights the evolving factors that may impair African American breast cancer patients' access to safe, effective breast reconstruction, which must be identified and resolved.

Effect of Immediate Implant-Based Breast Reconstruction After Mastectomy With and Without Acellular Dermal Matrix Among Women With Breast Cancer: A Randomized Clinical Trial.

Importance: The use of acellular dermal matrix (ADM) in implant-based breast reconstructions (IBBRs) is established practice. Existing evidence validating ADMs proposed advantages, including improved cosmetics and more single-stage IBBRs, is lacking. Objective: To evaluate whether IBBR with ADM results in fewer reoperations and increased health-related quality of life (HRQoL) compared with conventional IBBR without ADM. Design, Setting, and Participants: This was an open-label, multicenter, randomized clinical trial of women with primary breast cancer who planned for mastectomy and immediate IBBR, with a 2-year follow-up for all participants. Participants were enrolled at 5 breast cancer units in Sweden and the United Kingdom between 2014 and May 2017. Exclusion criteria included previous radiotherapy and neo-adjuvant chemotherapy. Data were analyzed until August 2017. Interventions: Participants were allocated to immediate IBBR with or without ADM. Main Outcomes and Measures: The primary trial end point was number of reoperations at 2 years. HRQoL, a secondary end point, was measured as patient-reported outcome measures using 3 instruments from the European Organization for Research and Treatment of Cancer Quality of life Questionnaire. Results: From start of enrollment on April 24, 2014, to close of trial on May 10, 2017, a total of 135 women were enrolled (mean [SD] age, 50.4 [9.5] years); 64 were assigned to have an IBBR procedure with ADM and 65 to the control group who had IBBR without ADM. There was no statistically significant difference between groups for the primary outcome. Of 129 patients analyzed at 2-year follow-up, 44 of 64 (69%) had at least 1 surgical event in the ADM group vs 43 of 65 (66%) in the control group. In the ADM group, 31 patients (48%) had at least 1 reoperation on the ipsilateral side vs 35 (54%) in the control group. The overall number of reoperations on the ipsilateral side were 42 and 43 respectively. Within the follow-up time of 24 months, 9 patients (14%) in the ADM group had the implant removed compared with 7 (11%) in the control group. We found no significant mean differences in postoperative patient-reported HRQoL domains, including perception of body image (mean difference, 3; 99% CI, -11 to 17; P = .57) and satisfaction with cosmetic outcome (mean difference, 8; 99% CI, -6 to 20; P = .11). Conclusions and Relevance: Immediate IBBR with ADM did not yield fewer reoperations compared with conventional IBBR without ADM, nor was IBBR with ADM superior in terms of HRQoL or patient-reported cosmetic outcomes. Patients treated for breast cancer contemplating ADM-supported IBBR should be informed about the lack of evidence validating ADM's suggested benefits.

Outcomes after mastectomy with immediate breast reconstruction for breast cancer in a multiethnic, middle-income Asian setting.

BACKGROUND: Although immediate breast reconstruction is increasingly becoming popular worldwide, evidence from resource-limited settings is scarce. We investigated factors associated with immediate breast reconstruction in a multiethnic, middle-income Asian setting. Short-term surgical complications, timing of initiation of chemotherapy, and survival outcomes were compared between women undergoing mastectomy alone and their counterparts receiving immediate breast reconstruction. METHODS: This historical cohort study included women who underwent mastectomy after diagnosis with stage 0 to stage IIIa breast cancer from 2011 to 2015 in a tertiary hospital. Multivariable regression analyses were used to assess factors associated with immediate breast reconstruction and to measure clinical outcomes. RESULT: Out of 790 patients with early breast cancer who had undergone mastectomy, only 68 (8.6%) received immediate breast reconstruction. Immediate breast reconstruction was independently associated with younger age at diagnosis, recent calendar years, Chinese ethnicity, higher education level, and invasive ductal carcinomas. Although immediate breast reconstruction was associated with a higher risk of short-term local surgical complications (adjusted odds ratio: 3.58 [95% confidence interval 1.75-7.30]), there were no significant differences in terms of delay in initiation of chemotherapy, 5-year disease-free survival, and 5-year overall survival between both groups in the multivariable analyses. CONCLUSION: Although associated with short-term surgical complications, immediate breast reconstruction after mastectomy does not appear to be associated with delays in initiation of chemotherapy, recurrence, or mortality after breast cancer. These findings are valuable in facilitating shared surgical decision-making, improving access to immediate breast reconstruction, and setting priorities for surgical trainings in middle-income settings.

Impact of insurance payer and socioeconomic status on type of autologous breast reconstruction.

INTRODUCTION: Autologous breast reconstruction has evolved from more morbid procedures that sacrificed the abdominal muscle (the TRAM or transverse rectus abdominus muscle flap) to "perforator" flaps. Commercial insurers recognized the higher technical demand of perforator flaps by creating procedural codes with higher professional fees. This study examined whether procedure code discrepancies between insurance payers disproportionally incentivize perforator flaps among the commercially insured. METHODS: Autologous breast reconstructions identified from the National Inpatient Sample (NIS) were subdivided into microvascular perforator (85.74, 85.75, 85.76), microvascular TRAM (85.73), and pedicled TRAM flaps (85.72). Demographics, comorbidities and access to care were compared. A logistic regression comparing microvascular reconstructions only was used to identify predictors for perforator flap reconstruction. RESULTS: A total of 66,968 cases of autologous breast reconstruction were identified. Perforator flaps were more likely among the commercially insured (p < 0.001) and higher insurance quartiles (p < 0.001).When comparing microvascular reconstruction, perforator flaps were 1.72 (p < 0.001) times more likely among the commercially insured. As compared to the lowest income quartile, the fourth quartile had an odds ratio of 1.36 (p < 0.001) for perforator flap reconstruction. CONCLUSION: The presence of a separate perforator flap billing code among the commercially insured may be exacerbating existing socioeconomic disparities in breast cancer reconstruction.

Perceived versus Patient-Reported Significance of Surgeon Gender in Breast Reconstruction.

BACKGROUND: Previous investigators demonstrated that female patients often prefer female providers. However, these studies have not determined whether there are gender preferences for breast reconstruction surgeons or whether the effects of surgeon gender impacts patient-reported outcomes. METHODS: Adult women were crowdsourced using Amazon Mechanical Turk to characterize societal preferences for the gender of breast and plastic surgeons in a hypothetical scenario. The authors also used data from the Mastectomy Reconstruction Outcomes Consortium to determine the association between surgeon gender and patient satisfaction after breast reconstruction. The BREAST-Q questionnaire was used to assess patient-reported outcomes at 3 months and 2 years following reconstruction. Regression analyses were performed to investigate the effects of surgeon gender on patient-reported outcomes. RESULTS: In total, 1413 surveys were collected. Forty-two percent preferred female plastic surgeons, 5 percent preferred male surgeons, and 53 percent reported no preference. The Mastectomy Reconstruction Outcomes Consortium analysis included 2236 patients of 55 male and nine female plastic surgeons. In this cohort, 1921 patients (82.2 percent) had male surgeons, whereas 415 patients (17.8 percent) had female surgeons. Regression analysis at 2 years revealed no differences in satisfaction with surgeon, outcome, or psychosocial well-being. Only satisfaction with information differed, as patients of female surgeons reported greater satisfaction in this category, with an adjusted mean difference of 2.82 (p = 0.018). CONCLUSIONS: Although nonpatient women hypothetically prefer female providers, surgeon gender makes little difference in actual patient satisfaction with breast reconstruction. More investigation is needed to determine whether the difference in information delivery is clinically significant and whether it reflects variations in practices between male and female surgeons.

A Matched Comparison of the Benefits of Breast Reduction on Health-Related Quality of Life.

BACKGROUND: Breast reduction surgery has consistently fallen within the top 10 surgical procedures performed by plastic surgeons. This is because of its capability to relieve the physical and psychological impact of macromastia. Although numerous women pursue consultation, many never undergo the procedure. The authors aim to quantify the impact of breast reduction surgery on quality of life by comparing patients who underwent breast reduction surgery with those who did not. METHODS: Patients seeking breast reduction surgery between 2016 and 2019 were identified. As standard-of-care, patients are surveyed during the consultation visit and postoperative visits using the BREAST-Q. The preoperative survey was readministered a second time for those who did not undergo breast reduction surgery. Propensity score matching, based on patient demographics, comorbidities, and breast examination, was used to balance baseline characteristics. RESULTS: A total of 100 propensity-matched patients were identified (operative, n = 78; nonoperative, n = 22). Mean participant age was 39.5 ± 25 years and mean body mass index was 31.1 ± 7.4 kg/m2. Quality of life significantly improved in each domain for those in the operative group (p < 0.05). Those who did not undergo breast reduction surgery realized no improvement in quality of life and had a downward trend in quality of life across two of the four domains. CONCLUSIONS: Breast reduction surgery offers a significant improvement in quality of life for macromastia. This matched study demonstrates that patients who are able to undergo breast reduction surgery have a statistically significant improvement in all aspects of quality of life, whereas nonsurgical patients experience no benefit with time, with a trend toward deterioration in specific domains.

The Incidence of Occult Malignant and High-Risk Pathologic Findings in Breast Reduction Specimens.

BACKGROUND: The goal of this study was to determine the incidence of occult malignancy and high-risk breast pathologic findings in patients who undergo breast reduction procedures. METHODS: Medical records of consecutive patients who underwent reduction mammaplasty performed by the senior authors (A.L. and G.W.C.) at Emory University Hospital between 1997 and 2018 were reviewed. Data regarding patient demographics, personal or family history of malignancy, operative technique, pathologic findings, and follow-up were extracted. Patients were categorized into two groups, those with and those without breast cancer. Group A patients underwent reduction for symptomatic macromastia, and group B underwent contralateral reduction for unilateral breast cancer treated with oncoplastic partial or total breast cancer reconstruction. Pathologic findings were divided into four groups; normal, benign, high-risk, and malignant. RESULTS: A total 1014 patients (1419 breast reductions) were included in the study. Comparing groups A and B, mean age was 37.8 ± 16.2 years versus 54.5 ± 11.1 years (p < 0.001), mean body mass index was 34.1 ± 7.6 kg/m2 versus 33.3 ± 7.4 kg/m2 (p = 0.2), and average reduction weight was 875.6 ± 491 g versus 723.7 ± 438 g (p < 0.001). The incidence of high-risk or malignant lesions was 1.8 percent (n = 15) in group A and 8 percent (n = 49) in group B (p < 0.001). On multivariable logistic regression analysis, age and personal history of breast cancer were positive predictors for high-risk and malignant lesions. CONCLUSIONS: The incidence of abnormal pathologic findings in breast reduction specimens is not uncommon, and occult malignancy or high-risk lesions can be found, especially in patients with contralateral breast cancer. Appropriate specimen orientation, diligence with checking the pathologic findings, and open communication with the pathologist are crucial. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Impact of COVID-19 Pandemic on Surgical Breast Cancer Patients Undergoing Neoadjuvant Therapy: A Multicentric Study.

BACKGROUND/AIM: Due to the SARS-CoV-2 pandemic, many scientific committees proposed neoadjuvant therapy (NACT) bridging treatment as a novel strategy and indication. The aim of the study was to evaluate the impact of COVID-19 pandemic on breast cancer patients undergoing NACT. PATIENTS AND METHODS: All breast cancer patients referred to two Breast Units during COVID-19-pandemic were enrolled. RESULTS: Out of 814 patients, 43(5.3%) were enrolled in the COVID-19-group and compared with 94 (7.9%) similar Pre-COVID-19 patients. We observed a reduction in the number of patients undergoing NACT, p=0.0019. No difference was reported in terms of clinical presentation, indications, and tumor response. In contrast, a higher number of vascular adverse events was reported (6.9% vs. 0% p=0.029). Immediate breast cancer reconstructions following invasive surgery suffered a significant slowdown (5.9% vs. 47.7%, p=0.019). CONCLUSION: COVID-19 caused a reduction in the number of patients undergoing NACT, with no changes in terms of indications, clinical presentation, and tumor response. Furthermore, there was an increased incidence of vascular events.

Factors Associated With State-Specific Medicaid Expansion and Receipt of Autologous Breast Reconstruction Among Patients Undergoing Mastectomy.

Importance: Despite demonstrated psychosocial benefits, autologous breast reconstruction remains underutilized. An analysis of the association between Medicaid expansion and autologous breast reconstruction has yet to be performed. Objective: To compare autologous breast reconstruction rates and determine the association between Medicaid expansion and breast reconstruction. Design, Setting, and Participants: A retrospective cross-sectional study was performed using the State Inpatient Database from January 1, 2012, through September 30, 2015, and included 51 340 patients. Patients were identified using the International Classification of Diseases, Ninth Revision, codes for breast cancer, mastectomy, and autologous breast reconstruction. Data from states that expanded Medicaid (New Jersey, New York, and Washington) were compared with states that did not expand Medicaid (Florida, North Carolina, and Wisconsin). Data were analyzed from June 1, 2020, through February 28, 2021. Exposures: The Patient Protection and Affordable Care Act's Medicaid expansion was implemented in 2014; the preexpansion period ranged from 2012 to 2013 (2 years), whereas the postexpansion period ranged from 2014 to 2015 quarter 3 (1.75 years). Main Outcomes and Measures: Primary outcomes included use of autologous breast reconstruction before and after expansion. Independent covariates included patient demographics, comorbidities, and state of residence. Results: Among 45 850 patients who underwent mastectomy and 9215 patients who received autologous breast reconstruction, 36 777 (67%) were White and 32 205 (59%) had private insurance. The use of immediate or delayed autologous reconstruction increased from 18.1% (4951 of 27 290) to 23.0% (4264 of 18 560) throughout the study period. Compared with 2012, the odds of reconstruction were 64% higher in 2015 (odds ratio [OR], 1.64; 95% CI, 1.48-1.80; P < .001). African American (OR, 1.43; 95% CI, 1.33-1.55; P < .001) and Hispanic (OR, 1.44; 95% CI, 1.31-1.60; P < .001) patients had higher odds of reconstruction compared with White patients regardless of state of residence. However, Medicaid expansion was associated with a 28% decrease in the odds of reconstruction (OR, 0.72; 95% CI, 0.61-0.87; P < .001) for African American patients, a 40% decrease (OR, 0.60; 95% CI, 0.50-0.74; P < .001) for Hispanic patients, and 20% decrease (OR, 0.80; 95% CI, 0.67-0.96; P = .01) for patients with Asian, Native American, or other minority race/ethnicity. Medicaid expansion was not associated with changes in the odds of reconstruction for White patients. Conclusions and Relevance: In this cross-sectional study, although the odds of receiving autologous breast reconstruction increased annually, Medicaid expansion was associated with decreased odds of reconstruction for African American patients, Hispanic patients, and other patients of color.

Case Volume-Dependent Changes in Operative Morbidity following Free Flap Breast Reconstruction: A 15-Year Single-Center Analysis.

BACKGROUND: Operative morbidity is a common yet modifiable feature of complex surgical procedures. With increasing case volume, improvement in morbidity has been reported through designated procedural processes and greater repetition. Defined as a volume-outcome association, improvement in breast reconstruction morbidity with increasing free flap volume requires further characterization. METHODS: A retrospective analysis was conducted among consecutive free flap patients using a two-microsurgeon model between January of 2002 and December of 2017. Patient demographics and operative characteristics were obtained from medical records. Complications including unplanned surgical intervention (take-back) and flap loss were obtained from prospectively kept databases. Individual surgeon operative volume was estimated by considering overall practice volume and correcting for the number of surgeons at any given time. RESULTS: During the study period, 3949 patients met inclusion criteria. A total of 6607 breasts underwent reconstruction with 6675 free flaps. Mean patient age was 50 ± 9.4 years and mean body mass index was 28.8 ± 5.0 kg/m2. Bilateral reconstruction was performed on 2633 patients (66.5 percent), with 4626 breasts (70.5 percent) reconstructed in the immediate setting. Overall, breast and donor-site complications were reported in 507 breasts (7.7 percent) and 607 cases (15.4 percent), respectively. Take-back was required in 375 cases (9.5 percent), with complete flap loss occurring in 57 cases (0.9 percent). Based on annual flaps per surgeon, the incidence of complications decreased with increasing volume (slope = -0.12; p = 0.056). CONCLUSION: Through procedural efficiency and execution of defined clinical processes using a two-microsurgeon model, increases in microsurgical breast reconstruction case volume result in decreased morbidity. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

A Comparison of Surgical Complications in Patients Undergoing Delayed versus Staged Tissue-Expander and Free-Flap Breast Reconstruction.

BACKGROUND: Patients undergoing mastectomy may not be candidates for immediate free-flap breast reconstruction because of medical comorbidities or postmastectomy radiation therapy. In this setting, flap reconstruction may be intentionally delayed or staged with tissue expander placement ("delayed-immediate" reconstruction). The optimal reconstructive choice and incidence of complications for these approaches remain unclear. METHODS: The authors retrospectively identified patients who underwent delayed [n = 140 (72 percent)] or staged [n = 54 (28 percent)] abdominal free-flap breast reconstruction between 2010 and 2018 and compared the incidence of postoperative complications. RESULTS: Patients undergoing staged reconstruction had a higher overall incidence of perioperative complications, including surgical-site infection (40.7 percent versus 6.5 percent; p < 0.001), wound healing complications (29.6 percent versus 12.3 percent; p = 0.004), hematoma (11.1 percent versus 0.7 percent; p < 0.001), and return to the operating room (27.8 percent versus 4.4 percent; p < 0.0001). These complications occurred predominately during the expansion stage, resulting in an 18.5 percent (n = 10) rate of tissue expander failure. Mean time from mastectomy to flap reconstruction was 476.8 days (delayed, 536.4 days; staged, 322.4 days; p < 0.001). At the time of flap reconstruction, there was no significant difference in the incidence of complications between the staged cohort versus the delayed cohort, including microsurgical complications (1.9 percent versus 4.3 percent; p = 0.415), total flap loss (0 percent versus 2.1 percent; p = 0.278), or fat necrosis (5.6 percent versus 5.0 percent; p = 0.875). CONCLUSIONS: The aesthetic and psychosocial benefits of staged free-flap breast reconstruction should be balanced with the increased risk of perioperative complications as compared to a delayed approach. Complications related to definitive flap reconstruction do not appear to be affected by the approach taken at the time of mastectomy. . CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Changes in Korean National Healthcare Insurance Policy and Breast Cancer Surgery Trend in Korea.

BACKGROUND: Since April 2015, the Korean National Health Insurance (NHI) has reimbursed breast cancer patients, approximately 50% of the cost of the breast reconstruction (BR) procedure. We aimed to investigate NHI reimbursement policy influence on the rate of immediate BR (IBR) following total mastectomy (TM). METHODS: We retrospectively analyzed breast cancer data between April 2011 and June 2016. We divided patients who underwent IBR following TM for primary breast cancer into "uninsured" and "insured" groups using their NHI statuses at the time of surgery. Univariate analyses determined the insurance influence on the decision to undergo IBR. RESULTS: Of 2,897 breast cancer patients, fewer uninsured patients (n = 625) underwent IBR compared with those insured (n = 325) (30.0% vs. 39.8%, P < 0.001). Uninsured patients were younger than those insured (median age [range], 43 [38-48] vs. 45 [40-50] years; P < 0.001). Pathologic breast cancer stage did not differ between the groups (P = 0.383). More insured patients underwent neoadjuvant chemotherapy (P = 0.011), adjuvant radiotherapy (P < 0.001), and IBR with tissue expander insertion (P = 0.005) compared with those uninsured. CONCLUSION: IBR rate in patients undergoing TM increased after NHI reimbursement.

Patient Satisfaction Increases with Nipple Reconstruction following Autologous Breast Reconstruction.

BACKGROUND: Nipple reconstruction has been linked to patient satisfaction; however, there is debate about the validity of these findings in autologous breast reconstruction patients. This study hypothesized that satisfaction would increase with nipple reconstruction following autologous breast reconstruction. METHODS: A comparison study was performed of autologous breast reconstruction patients. Patients completed a survey that included BREAST-Q and nipple satisfaction measures. A chart review identified reconstructive details. RESULTS: A total of 191 patients completed the survey (48 percent response rate), with an average age of 53.7 ± 10.0 years and follow-up time of 2.8 ± 1.5 years. Nipple-areola complex reconstruction was completed in 33 percent of patients (63 of 191). Nipple-areola complex tattoos were used most frequently [n = 37 (58 percent)], followed by local flaps [n = 10 (16 percent)], free nipple-areola complex grafts [n = 9 (14 percent)], and a combination of local flaps and tattoos [n = 7 (11 percent)]. In comparison to women who did not undergo nipple-areola complex reconstruction, women who underwent any type of nipple reconstruction had a statistically higher BREAST-Q score for Sexual Well-Being (60 ± 24 versus 50 ± 22; p = 0.01), Postoperative Satisfaction with Breasts (65 ± 11 versus 61 ± 12; p = 0.01), and Satisfaction with Surgeon (97 ± 6 versus 93 ± 16; p = 0.009). The average nipple satisfaction score was 74 ± 19. There were correlations between the nipple satisfaction score and BREAST-Q scores for Sexual Well-Being (r = 0.50; p < 0.001), Psychosocial Well-Being (r = 0.43; p < 0.001), and Postoperative Satisfaction with Breasts (r = 0.43; p < 0.001). CONCLUSION: Reconstruction of the nipple-areola complex is an important part of autologous breast reconstruction, resulting in increased sexual well-being and satisfaction with reconstructed breasts.

Reconstruction in Women with T4 Breast Cancer after Neoadjuvant Chemotherapy: When Is It Safe?

BACKGROUND: Despite limited evidence regarding its safety, immediate reconstruction (IR) is increasingly offered to women with T4 breast cancer. We compared outcomes after IR, delayed reconstruction (DR), and no reconstruction (NR) in patients treated with neoadjuvant chemotherapy (NAC) and postmastectomy radiation therapy (PMRT) for T4 disease. STUDY DESIGN: We retrospectively identified consecutive women with T4 tumors treated with trimodality therapy from January 2007 through December 2019. Clinicopathologic characteristics, complications requiring reoperation, time to PMRT, and recurrence patterns were compared. The cumulative incidence of local recurrence (LR) was estimated using Kaplan-Meier methods. RESULTS: Of the 269 women identified, the median (IQR) age was 52 (45-62) years; 164 women (61%) had T4d disease. Forty-five women (17%) had IR, 41 (15%) had DR, and 183 (68%) had NR. IR was independently associated with T4a-c disease (odds ratio [OR], 5.75; 95% CI, 2.57-12.87; p < 0.001) and younger age (OR 0.91; 95% CI, 0.86-0.94; p < 0.001). The risk of complications after IR was 22% overall and 46% in T4d patients (6/13), compared with 4.4% overall for NR and 7.3% for DR (p < 0.001). IR was associated with >8-week interval to PMRT (p < 0.001). At a median (range) follow-up of 4.2 (0.2-13) years, the median time to first recurrence was 18 months and was similar between groups (p = 0.13). The cumulative incidence of LR was 16% for T4d disease and 2.2% for T4a-c disease (p < 0.001). CONCLUSIONS: After IR, women with T4 tumors, particularly T4d disease, experienced delayed initiation of adjuvant treatment and substantial morbidity, suggesting that an interval of >18 months between mastectomy and reconstruction is advisable.
