Oncological Safety of Autologous Fat Grafting for Breast Reconstruction.

BACKGROUND: Autologous fat grafting has become a vital component of breast reconstruction. However, concerns remain regarding the safety of fat grafting after oncological resection and breast reconstruction. The purpose of the study was to evaluate the association of fat grafting after breast reconstruction with metastasis and death in breast cancer patients. METHODS: A retrospective, population-based cohort study was conducted using deidentified claims data from 2001 to 2018 and included privately insured patients with breast cancer who underwent breast reconstruction after surgical resection. Breast reconstruction patients who underwent fat grafting were compared with those not undergoing fat grafting, evaluating metastasis and death up to 15 years after reconstruction. One-to-one propensity score matching was used to account for selection bias on patient risk factors comparing those with and without fat grafting. RESULTS: A total of 4709 patients were identified who underwent breast reconstruction after lumpectomy or mastectomy, of which 368 subsequently underwent fat grafting. In the propensity score-matched patients, fat grafting was not associated with an increased risk of lymph node metastasis (9.7% fat-grafted vs 11.4% in non-fat-grafted, P = 0.47) or distant metastasis (9.1% fat-grafted vs 10.5% in non-fat-grafted, P = 0.53). There was no increased risk of all-cause mortality after fat grafting for breast reconstruction (3.9% fat-grafted vs 6.6% non-fat-grafted, P = 0.10). CONCLUSIONS: Among breast cancer patients who subsequently underwent fat grafting, compared with no fat grafting, no significant increase was observed in distant metastasis or all-cause mortality. These findings suggest that autologous fat grafting after oncologic resection and reconstruction was not associated with an increased risk of future metastasis or death.

Towards Patient-centered Decision-making in Breast Cancer Surgery: Machine Learning to Predict Individual Patient-reported Outcomes at 1-year Follow-up.

OBJECTIVE: We developed, tested, and validated machine learning algorithms to predict individual patient-reported outcomes at 1-year follow-up to facilitate individualized, patient-centered decision-making for women with breast cancer. SUMMARY OF BACKGROUND DATA: Satisfaction with breasts is a key outcome for women undergoing cancer-related mastectomy and reconstruction. Current decision-making relies on group-level evidence which may lead to suboptimal treatment recommendations for individuals. METHODS: We trained, tested, and validated 3 machine learning algorithms using data from 1921 women undergoing cancer-related mastectomy and reconstruction conducted at eleven study sites in North America from 2011 to 2016. Data from 1921 women undergoing cancer-related mastectomy and reconstruction were collected before surgery and at 1-year follow-up. Data from 10 of the 11 sites were randomly split into training and test samples (2:1 ratio) to develop and test 3 algorithms (logistic regression with elastic net penalty, extreme gradient boosting tree, and neural network) which were further validated using the additional site's data.AUC to predict clinically-significant changes in satisfaction with breasts at 1-year follow-up using the validated BREAST-Q were the outcome measures. RESULTS: The 3 algorithms performed equally well when predicting both improved or decreased satisfaction with breasts in both testing and validation datasets: For the testing dataset median accuracy = 0.81 (range 0.73-0.83), median AUC = 0.84 (range 0.78-0.85). For the validation dataset median accuracy = 0.83 (range 0.81-0.84), median AUC = 0.86 (range 0.83-0.89). CONCLUSION: Individual patient-reported outcomes can be accurately predicted using machine learning algorithms, which may facilitate individualized, patient-centered decision-making for women undergoing breast cancer treatment.

BMI is Not Associated with Chest-Specific Body Image, Complications or Revisions in Gender-Affirming Mastectomy: A Single-Center Cross-Sectional Study.

OBJECTIVE: To analyze the impact of Body Mass Index (BMI) on clinical and patient-reported outcomes following gender-affirming mastectomy (GM). BACKGROUND: BMI is a barrier for obese patients seeking GM despite increasing evidence that it is safe in this population. Currently little is known about the impact of BMI on chest-specific body image and satisfaction following GM. METHODS: This single-center, cross-sectional study included individuals 18 years and older who underwent GM between 1990-2020 and were at least 2 years post-operative. Patient-reported chest-specific body image was measured using the BODY-Q and Gender Congruence and Life Satisfaction (GCLS) chest subscales. Satisfaction was measured using the Holmes-Rovner Satisfaction with Decision (SWD) scale. Clinical and demographic variables were identified from chart review. Bivariate analysis was performed to determine if BMI was associated with chest-specific body image, satisfaction, complications within 30 days or revisions in GM. RESULTS: Two hundred twenty-seven individuals meeting eligibility criteria were contacted to participate and one hundred thirty-seven responded (60.4% response rate). The mean age was 29.1 (SD=9.0) and mean BMI was 30.9 (SD=8.0), with 26.4% (N=60) of the cohort having a BMI>35. Chest-specific body image, and satisfaction with decision did not vary by BMI or breast resection weight. Complications and revisions were not associated with BMI. CONCLUSION: Individuals undergoing GM reported high rates of satisfaction following GM regardless of BMI. Complication and revision rates did not vary significantly by BMI or breast resection weight. Surgeons should re-evaluate the role BMI plays in patient selection and counseling for GM.

Gender Affirming Mastectomy Improves Quality of Life in Transmasculine Patients: A Single-center Prospective Study.

OBJECTIVE: To determine the impact of gender-affirming mastectomy on depression, anxiety, and body image. BACKGROUND: There are many cross-sectional and ad-hoc studies demonstrating the benefits of gender-affirming surgery. There are few prospective investigations of patient-reported outcomes in gender-affirming surgery using validated instruments. METHODS: In this prospective study, patients presenting to the University of Michigan for gender-affirming Mastectomy were surveyed preoperatively and 6-months postoperatively. Primary outcomes were patient-reported measurements of anxiety measured by General Anxiety Disorder-7, depression measured by Patient Health Questionnaire-9, body image measured by BODY-Q and Body Image Quality of Life Index, psychosocial and sexual functioning measured by BREAST-Q, and satisfaction with decision measured by BREAST-Q. Linear regression analysis was used to control for presence of complication and existing history of mental health conditions. RESULTS: A total of 70 patients completed the study. The average age of participants was 26.7. The mean Patient Health Questionnaire-9 score pre-operatively was 7.8 and postoperatively was 5.4 ( P =0.001). The mean preoperative and postoperative General Anxiety Disorder-7 scores were 7.6 and 4.6, respectively ( P <0.001). There were significant improvements in both psychosocial (35 to 79.2, P <0.001) and sexual (33.9 to 67.2, P< 0.001) functioning related to chest appearance as measured by the BREAST-Q and global psychosocial functioning (-15.6 to +32, P <0.001) as measured by the Body Image Quality of Life Index. Satisfaction with chest contour (14.3 to 93.8, P <0.001) and nipple appearance (29.3 to 85.9, P <0.001) measured by the BODY-Q significantly improved. Patients had a mean satisfaction with outcome score of 93.1. CONCLUSIONS: Patients undergoing gender-affirming mastectomy in this single-center prospective study reported significant improvements in anxiety, depression, body image, psychosocial, and sexual functioning after this procedure. Patients were extremely satisfied with the decision to undergo this operation.

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.

Comparing Nipple-sparing Mastectomy to Secondary Nipple Reconstruction: A Multi-institutional Study.

OBJECTIVE: The primary aim of this study was to compare patient-reported outcomes (PROs) of women who underwent immediate implant-based breast reconstruction (IBBR) after receiving either: (1) nipple-sparing mastectomy (NSM) or (2) simple mastectomy with subsequent nipple reconstruction (SNR). BACKGROUND: The goal of post-mastectomy breast reconstruction is to restore body image and quality-of-life after mastectomy, but removal of the nipple-areolar complex may have its own negative psychosocial consequences. NSM may have increased in popularity due to its perceived oncologic safety in many women and to reports of superior aesthetic results with this technique. Despite the increased utilization of NSM, few studies have evaluated the impact of NSM on PROs and complications in women undergoing immediate IBBR. METHODS: We performed a secondary analysis of the Mastectomy Reconstruction Outcomes Consortium study, a multicenter, prospective cohort study that recruited patients between February 2012 and July 2015. The primary aim of this study was to compare PROs as measured by BREAST-Q scores between women who underwent IBBR after NSM versus SNR. The secondary aim was to compare complication rates. Mixed-effects regression models controlled for demographic and clinical covariates. RESULTS: Of the 600 women in the study, 286 (47.7%) underwent NSM. After controlling for baseline patient characteristics, we found no significant differences in satisfaction with breast, psychosocial well-being, physical well-being or sexual well-being between women undergoing NSM versus SNR. Mastectomy type was not a significant predictor of complications or reconstructive failure. CONCLUSIONS: Despite reports of superior aesthetics for NSM over simple mastectomy with nipple reconstruction in immediate IBBR, we found no significant differences at 2 years after reconstruction in patient satisfaction, quality-of-life, or complication rates.

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.

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.

Complications in Postmastectomy Breast Reconstruction: One-year Outcomes of the Mastectomy Reconstruction Outcomes Consortium (MROC) Study.

OBJECTIVE: In postmastectomy reconstruction, procedure choice is heavily influenced by the relative risks of the various options. This study sought to evaluate complications in a large, multicenter patient population. SUMMARY OF BACKGROUND DATA: Previous studies have reported widely varying complication rates, but have been limited by their single center designs and inadequate controlling for confounders in their analyses. METHODS: Eleven sites enrolled women undergoing first time, immediate, or delayed reconstruction following mastectomy for cancer treatment or prophylaxis. Procedures included expander/implant, latissimus dorsi (LD), pedicle transverse rectus abdominis musculocutaneous (PTRAM), free TRAM (FTRAM), and deep inferior epigastric perforator (DIEP) techniques. Data were gathered pre- and postoperatively from medical records. Separate logistic regressions were conducted for all complications and major complications (those requiring rehospitalization and/or reoperation) within 1 year. Odds ratios (ORs) were calculated for procedure type, controlling for site, demographic, and clinical variables. RESULTS: Complication rates for 2234 patients were analyzed. Compared with expander/implant reconstructions, LD (OR) 1.95, P = 0.026), PTRAM (OR 1.89, P = 0.025), FTRAM (OR 1.94, P = 0.011), and DIEP (OR 2.22, P < 0.001) procedures were associated with higher risks of complications. Significantly higher risks were also associated with older age, higher body mass index (BMI), immediate reconstruction, bilateral procedures, and radiation. For major complications, regression showed significantly greater risks for PTRAM (OR 1.86, P = 0.044) and DIEP (OR 1.75, P = 0.004), than expander/implant reconstructions. Failure rates were relatively low, ranging from 0% for PTRAM to 5.9% for expander/implant reconstructions. CONCLUSION: In this multicenter analysis, procedure choice and other patient variables were significant predictors of 1-year complications in breast reconstruction. These findings should be considered in counseling patients on reconstructive options.

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.

Nonresponse bias in survey research: lessons from a prospective study of breast reconstruction.

BACKGROUND: Survey-based research is essential for evaluating the outcomes of health care in an era of patient-centered care. However, many such studies are hampered by poor response rates in completion of study questionnaires, thus limiting the generalizability of any findings. The objectives of this analysis were to identify independent variables associated with nonresponse to surveys following breast reconstruction to improve future patient-reported outcomes research. MATERIALS AND METHODS: The Mastectomy Reconstruction Outcomes Consortium is a prospective cohort study involving 11 leading medical centers from the United States and Canada. Nonresponse rates for surveys assessing satisfaction with breast, satisfaction with care (BREAST-Q), depression (Patient Health Questionnaire-9), and anxiety (Generalized Anxiety Disorder-7) were measured at 1 y and 2 y postoperatively. Clinical complication rates were compared between responders and nonresponders, and multivariable models were used to assess predictors of nonresponse. RESULTS: Among 2856 women in the analytic cohort, 1882 (65.9%) underwent implant-based, 817 (28.6%) received autologous, and 157 (5.5%) underwent latissimus dorsi myocutaneous flap breast reconstructions. Nonresponse rates to surveys at 1 y and 2 y were 27.8% and 34.4%, respectively. Race, ethnicity, and annual household income were associated with nonresponse to surveys. Women who underwent implant-based procedures were less likely to complete long-term surveys. CONCLUSIONS: As survey-based research plays an increasingly prominent role in evaluating the outcomes of breast reconstruction, we found socioeconomic and procedure-related differences in survey response rates. Investigators must consider systematic differences in response rates among particular groups of women on the generalizability and validity of findings and perform rigorous nonresponse bias analyses.

Radiotherapy in the setting of breast reconstruction: types, techniques, and timing.

As the use of breast reconstruction and postmastectomy radiotherapy (PMRT) has increased over the past decade, the typical approach to integrating radiotherapy with breast reconstruction has provoked intense controversy in the management of breast cancer. PMRT can lead to an increased frequency of complications in the reconstructed breast. Conversely, the reconstructed breast can increase the complexity of radiotherapy delivery. How to minimise the frequency of complications without compromising oncological or cosmetic outcomes of the reconstructed breast is an important shared multidisciplinary goal for oncologists and their patients. Several questions remain, however, regarding the type of reconstruction that should be used with PMRT, when reconstruction should be done relative to PMRT and whether radiotherapy treatment should be directed towards the tissue expander or the implant for women who opt for a two-stage expander-implant reconstruction. Following advances in the planning of radiotherapy treatment, new questions about the application of these technologies in the setting of breast reconstruction have arisen. In this Review, we address these questions by reviewing contemporary evidence on the optimal integration of radiotherapy and breast reconstruction in the management of breast cancer.

Tradeoffs Associated With Contralateral Prophylactic Mastectomy in Women Choosing Breast Reconstruction: Results of a Prospective Multicenter Cohort.

OBJECTIVE: Assess postoperative morbidity and patient-reported outcomes after unilateral and bilateral breast reconstruction in patients with unilateral breast cancer. BACKGROUND: Relatively little is known about the morbidity associated with and changes in quality of life experienced by patients who undergo contralateral prophylactic mastectomy (CPM) and breast reconstruction. This information would be valuable for decision making in patients with unilateral breast cancer. METHODS: Women undergoing mastectomy and breast reconstruction for unilateral breast cancer were recruited for this prospective observational study. Postoperative complications after implant and autologous breast reconstruction in patients undergoing unilateral or bilateral mastectomy were recorded. Preoperative and 1 year patient-reported outcomes were measured. Univariate tests and logistic regression analyses were performed, studying the effects of reconstructive method, laterality, and risk factors on surgical complication rates, patient satisfaction, and anxiety. RESULTS: We identified 1144 women who underwent either unilateral (47.2%) or bilateral (52.8%) mastectomies with reconstruction. Bilateral autologous (odds ratio 1.73, 95% confidence interval 1.07-2.81) and implant reconstructions (odds ratio 1.73, 95% confidence interval 1.22-2.47) were associated with a higher risk of complications compared with unilateral reconstructions. Baseline anxiety was greater in women who chose bilateral compared with unilateral implant reconstructions (P = 0.001). There was no difference in anxiety levels between groups postoperatively. Postoperatively, women who chose CPM with implant reconstructions were more satisfied with their breasts than women with unilateral reconstructions (P = 0.034). CONCLUSIONS: Although higher postoperative complications were observed after CPM and reconstruction, these procedures were associated with decreased anxiety levels and improved satisfaction with breasts for women who underwent implant reconstructions.

Autologous Fat Grafting After Breast Reconstruction in Postmastectomy Patients: Complications, Biopsy Rates, and Locoregional Cancer Recurrence Rates.

BACKGROUND: Autologous fat grafting is widely used for refinements in postmastectomy breast reconstruction. However, there are few studies evaluating outcomes in this patient population. The purpose of this study was to assess outcomes of autologous fat grafting after breast reconstruction in postmastectomy patients. METHODS: We retrospectively reviewed the records of consecutive postmastectomy patients who underwent autologous fat grafting after breast reconstruction at a university center over a 5-year period. Patients with at least 6 months of follow-up were included. Medical records were reviewed for demographics, operative details, complications, incidence of palpable masses, and/or suspicious breast imaging findings requiring biopsy, and locoregional cancer recurrence. Descriptive statistics were generated. RESULTS: Between January 2008 and July 2013, 108 women and a total of 167 breast reconstructions underwent autologous fat grafting for revision of postmastectomy breast reconstruction. Their ages ranged from 22 to 71 years (mean, 48 years). Fat grafts were harvested, processed, and injected using the Coleman technique. The mean number of fat grafting procedures was 1.3 (range, 1-4) per breast. Follow-up ranged from 6 to 57 months (mean, 20.2 months). Fifty-three (31.7%) breasts underwent imaging after autologous fat grafting. Suspicious imaging findings requiring biopsy were discovered in 4 (2.4%) breasts, and clinically palpable lesions combined with suspicious imaging findings requiring biopsy were present in another 4 (2.4%) breasts. All 8 biopsies showed fat necrosis, scar, or oil cysts without evidence of malignancy. One (0.6%) local complication (a wound infection at the recipient site requiring oral antibiotics) after autologous fat grafting was reported. During the limited follow-up period, there were no locoregional cancer recurrences. CONCLUSIONS: Autologous fat grafting in conjunction with breast reconstruction resulted in a biopsy rate of 4.8%, and no cases of locoregional cancer recurrence were observed. Based on these preliminary findings, autologous fat grafting appears to be a relatively safe procedure for refinement of the reconstructed breast in postmastectomy patients.

Understanding and Optimizing the Patient Experience in Breast Reconstruction.

BACKGROUND: Optimizing the patient experience is a central pillar in healthcare quality. Although this may be recognized as important in breast reconstruction, surgeons are often unaware of how well they and members of their team achieve this goal. The objective of our study was to evaluate patient satisfaction with the experience of care in a multicenter, prospective cohort of patients undergoing breast reconstruction. Specifically, we sought to determine which aspects of the care experience might be most amenable to quality improvement. METHODS: As part of the Mastectomy Reconstruction Outcomes Consortium Study, 2093 patients were recruited from 11 centers in North America. Of these, 1534 (73.3%) completed the BREAST-Q Satisfaction with Care scales (satisfaction with information, surgeon, medical team, and office staff) at 3 months after reconstruction and were included in the analysis. RESULTS: Patients scored lowest on 'Satisfaction with Information' (mean = 72.8) compared to all other Satisfaction with Care scales (mean, 89.5-95.5). Patients with immediate reconstruction were less satisfied with their plastic surgeon compared to those with delayed reconstruction. The racial category, "Other" (Asians, Pacific Islanders, Hawaiians, American Indians), was the least satisfied group across all Satisfaction with Care scales. CONCLUSIONS: Patients undergoing breast reconstruction perceive significant gaps in their knowledge and understanding of expected outcomes. Immediate reconstruction patients and minority racial groups may require additional resources and attention. As a means to improve quality of care, these findings highlight an important unmet need and suggest that improving patient education may be central to providing patient-centered care.

Quantifying Nipple-Areolar Complex Shape and Location After Transmasculine Top Surgery: A Study of Postoperative Photographs Posted on Social Media and Surgeons' Professional Websites.

Purpose: The transgender community utilizes online platforms to view and share postoperative masculinizing top surgery photographs. However, the quantitative and qualitative nature of these photographs is unknown. We aimed to conduct an analysis of postoperative online photographs for nipple-areolar complex (NAC) shape and location, and compare social media platforms to World Professional Association for Transgender Health (WPATH) surgeons' websites and published cis-male chest proportions. Methods: In a cross-sectional analysis (April to May 2019), social media (Instagram and Reddit) and WPATH surgeon website postoperative top surgery photographs were analyzed. Areola height (AH):areola width (AW), NAC horizontal (inter-nipple distance [IND]:chest width [CW]) and vertical placement (sternal notch to nipple line [SN-NL]:sternal notch to umbilicus [SN-U]), and vertical scar placement (sternal notch to scar line [SN-SL]:SN-U) ratios were assessed on MATLAB. Data were compared to published cis-male proportions. Photograph skin color, soft tissue redundancy, and scar location were also analyzed. Results: We analyzed 304 social media and 192 surgeons' website photographs qualitatively, and 139 social media and 189 surgeons' photographs quantitatively. Means (standard deviation) for postoperative photographs were AH:AW 1.12±0.24, IND:CW 0.68±0.07, SN-NL:SN-U 0.37±0.06. Most ratios significantly differed from published cis-male ratios (p<0.001). Photographs from WPATH surgeons' websites differed from social media platforms in SN-NL:SN-U and SN-SL:SN-U (p<0.001), and in scar location and soft tissue redundancy (p=0.012). Conclusion: Postoperative top surgery photographs on online platforms showed more vertically oval, caudally positioned, and in many cases wider-spaced NACs than cis-male proportions. Our study highlights variability in results of masculinizing top surgery as it relates to an emerging source of information; online photographs.

Outcomes of breast reconstruction in patients with stage IV breast cancer.

BACKGROUND: Patients with Stage IV breast cancer are living longer but breast reconstruction in this setting remains controversial. There is limited research evaluating the benefits of breast reconstruction in this patient cohort. STUDY DESIGN: Drawing from the Mastectomy Reconstruction Outcomes Consortium (MROC) dataset, a prospective cohort study that involved 11 leading medical centers in the US and Canada, we compared patient-reported outcomes (PROs) assessed utilizing the BREAST-Q, a condition-specific, validated patient-reported outcome measure (PROM) for mastectomy reconstruction, as well as complications between a cohort of patients with Stage IV disease undergoing reconstruction and a control group of women with Stage I-III disease also receiving reconstruction. RESULTS: Among the MROC population, 26 patients with Stage IV and 2613 women with Stage I-III breast cancer underwent breast reconstruction. Preoperatively, the Stage IV cohort reported significantly lower baseline scores for satisfaction with breast (p = 0.004), psychosocial well-being (p = 0.043) and sexual well-being (p = 0.001), compared with Stage I-III women. Following breast reconstruction, Stage IV patients' mean PRO scores improved over baseline and were not significantly different from those of Stage I-III reconstruction patients. There were also no significant differences in overall/any (p = 0.782), major (p = 0.751) or minor complication (p = 0.787) rates between the two groups at two years following reconstruction. CONCLUSIONS: The findings in this study suggest that breast reconstruction offers significant quality-of-life benefits for women with advanced breast cancer with no increase in postoperative complications and thus may be a reasonable option in this clinical setting.

Long-Term Regret and Satisfaction With Decision Following Gender-Affirming Mastectomy.

Importance: There has been increasing legislative interest in regulating gender-affirming surgery, in part due to the concern about decisional regret. The regret rate following gender-affirming surgery is thought to be approximately 1%; however, previous studies relied heavily on ad hoc instruments. Objective: To evaluate long-term decisional regret and satisfaction with decision using validated instruments following gender-affirming mastectomy. Design, Setting, and Participants: For this cross-sectional study, a survey of patient-reported outcomes was sent between February 1 and July 31, 2022, to patients who had undergone gender-affirming mastectomy at a US tertiary referral center between January 1, 1990, and February 29, 2020. Exposure: Decisional regret and satisfaction with decision to undergo gender-affirming mastectomy. Main Outcomes and Measures: Long-term patient-reported outcomes, including the Holmes-Rovner Satisfaction With Decision scale, the Decision Regret Scale, and demographic characteristics, were collected. Additional information was collected via medical record review. Descriptive statistics and univariable analysis using Fisher exact and Wilcoxon rank sum tests were performed to compare responders and nonresponders. Results: A total of 235 patients were deemed eligible for the study, and 139 responded (59.1% response rate). Median age at the time of surgery was 27.1 (IQR, 23.0-33.4) years for responders and 26.4 (IQR, 23.1-32.7) years for nonresponders. Nonresponders (n = 96) had a longer postoperative follow-up period than responders (median follow-up, 4.6 [IQR, 3.1-8.6] vs 3.6 [IQR, 2.7-5.3] years, respectively; P = .002). Nonresponders vs responders also had lower rates of depression (42 [44%] vs 94 [68%]; P < .001) and anxiety (42 [44%] vs 97 [70%]; P < .001). No responders or nonresponders requested or underwent a reversal procedure. The median Satisfaction With Decision Scale score was 5.0 (IQR, 5.0-5.0) on a 5-point scale, with higher scores noting higher satisfaction. The median Decision Regret Scale score was 0.0 (IQR, 0.0-0.0) on a 100-point scale, with lower scores noting lower levels of regret. A univariable regression analysis could not be performed to identify characteristics associated with low satisfaction with decision or high decisional regret due to the lack of variation in these responses. Conclusions and Relevance: In this cross-sectional survey study, the results of validated survey instruments indicated low rates of decisional regret and high levels of satisfaction with decision following gender-affirming mastectomy. The lack of dissatisfaction and regret impeded the ability to perform a more complex statistical analysis, highlighting the need for condition-specific instruments to assess decisional regret and satisfaction with decision following gender-affirming surgery.
