TCF1-LEF1 co-expression identifies a multipotent progenitor cell (TH2-MPP) across human allergic diseases.

Repetitive exposure to antigen in chronic infection and cancer drives T cell exhaustion, limiting adaptive immunity. In contrast, aberrant, sustained T cell responses can persist over decades in human allergic disease. To understand these divergent outcomes, we employed bioinformatic, immunophenotyping and functional approaches with human diseased tissues, identifying an abundant population of type 2 helper T (TH2) cells with co-expression of TCF7 and LEF1, and features of chronic activation. These cells, which we termed TH2-multipotent progenitors (TH2-MPP) could self-renew and differentiate into cytokine-producing effector cells, regulatory T (Treg) cells and follicular helper T (TFH) cells. Single-cell T-cell-receptor lineage tracing confirmed lineage relationships between TH2-MPP, TH2 effectors, Treg cells and TFH cells. TH2-MPP persisted despite in vivo IL-4 receptor blockade, while thymic stromal lymphopoietin (TSLP) drove selective expansion of progenitor cells and rendered them insensitive to glucocorticoid-induced apoptosis in vitro. Together, our data identify TH2-MPP as an aberrant T cell population with the potential to sustain type 2 inflammation and support the paradigm that chronic T cell responses can be coordinated over time by progenitor cells.

Frail but Resilient: Frailty in Autologous Breast Reconstruction is Associated with Worse Surgical Outcomes but Equivalent Long-Term Patient-Reported Outcomes.

BACKGROUND: Frailty is associated with higher risk of complications following breast reconstruction, but its impact on long-term surgical and patient-reported outcomes has not been investigated. We examined the association of the five-item modified frailty index (MFI) score with long-term surgical and patient-reported outcomes in autologous breast reconstruction. PATIENTS AND METHODS: We conducted a retrospective cohort study of consecutive patients who underwent mastectomy and autologous breast reconstruction between January 2016 and April 2022. Primary outcome was any flap-related complication. Secondary outcomes were patient-reported outcomes and predictors of complications in the frail cohort. RESULTS: We identified 1640 reconstructions (mean follow-up 24.2 ± 19.2 months). In patients with MFI ≥ 2, the odds of surgical [odds ratio (OR) 2.13, p = 0.023] and medical (OR 17.02, p < 0.001) complications were higher than in nonfrail patients. We found no significant difference in satisfaction with the breast (p = 0.287), psychosocial well-being (p = 0.119), or sexual well-being (p = 0.314) according to MFI score. Chronic obstructive pulmonary disease was an independent predictor of infection (OR 3.70, p = 0.002). Tobacco use (OR 7.13, p = 0.002) and contralateral prophylactic mastectomy (OR 2.36, p = 0.014) were independent predictors of wound dehiscence. Dependent functional status (OR 2.36, p = 0.007) and immediate reconstruction (compared with delayed reconstruction; OR 3.16, p = 0.026) were independent predictors of skin flap necrosis. Dependent functional status was also independently associated with higher odds of reoperation (OR 2.64, p = 0.011). CONCLUSION: Frailty is associated with higher risk of complications in breast reconstruction, but there is no significant difference in long-term patient-reported outcomes. MFI should be considered in breast reconstruction to improve outcomes in high-risk frail patients.

Remote Symptom Monitoring with Clinical Alerts Following Mastectomy: Do Early Symptoms Predict 30-Day Surgical Complications.

BACKGROUND: Electronic patient-reported outcome measures (ePROMs) for real-time remote symptom monitoring facilitate early recognition of postoperative complications. We sought to determine whether remote, electronic, patient-reported symptom-monitoring with Recovery Tracker predicts 30-day readmission or reoperation in outpatient mastectomy patients. METHODS: We conducted a retrospective review of breast cancer patients who underwent outpatient (< 24-h stay) mastectomy with or without reconstruction from April 2017 to January 2022 and who received the Recovery Tracker on Days 1-10 postoperatively. Of 5,130 patients, 3,888 met the inclusion criteria (2,880 mastectomy with immediate reconstruction and 1,008 mastectomy only). We focused on symptoms concerning for surgical complications and assessed if symptoms reaching prespecified alert levels-prompting a nursing call-predicted risk of 30-day readmission or reoperation. RESULTS: Daily Recovery Tracker response rates ranged from 45% to 70%. Overall, 1,461 of 3,888 patients (38%) triggered at least one alert. Most red (urgent) alerts were triggered by pain and fever; most yellow (less urgent) alerts were triggered by wound redness and pain severity. The 30-day readmission and reoperation rates were low at 3.8% and 2.4%, respectively. There was no statistically significant association between symptom alerts and 30-day reoperation or readmission, and a clinically relevant increase in risk can be excluded (odds ratio 1.08; 95% confidence interval 0.8-1.46; p = 0.6). CONCLUSIONS: Breast cancer patients undergoing mastectomy with or without reconstruction in the ambulatory setting have a low burden of concerning symptoms, even in the first few days after surgery. Patients can be reassured that symptoms that do present resolve quickly thereafter.

Reducing Disparities: Regional Anesthesia Blocks for Mastectomy with Reconstruction Within Standardized Regional Anesthesia Pathways.

BACKGROUND: Recent data suggest disparities in receipt of regional anesthesia prior to breast reconstruction. We aimed to understand factors associated with block receipt for mastectomy with immediate tissue expander (TE) reconstruction in a high-volume ambulatory surgery practice with standardized regional anesthesia pathways. PATIENTS AND METHODS: Patients who underwent mastectomy with immediate TE reconstruction from 2017 to 2022 were included. All patients were considered eligible for and were offered preoperative nerve blocks as part of routine anesthesia care. Interpreters were used for non-English speaking patients. Patients who declined a block were compared with those who opted for the procedure. RESULTS: Of 4213 patients who underwent mastectomy with immediate TE reconstruction, 91% accepted and 9% declined a nerve block. On univariate analyses, patients with the lowest rate of block refusal were white, non-Hispanic, English speakers, patients with commercial insurance, and patients undergoing bilateral reconstruction. The rate of block refusal went down from 12 in 2017 to 6% in 2022. Multivariable logistic regression demonstrated that older age (p = 0.011), Hispanic ethnicity (versus non-Hispanic; p = 0.049), Medicaid status (versus commercial insurance; p < 0.001), unilateral surgery (versus bilateral; p = 0.045), and reconstruction in earlier study years (versus 2022; 2017, p < 0.001; 2018, p < 0.001; 2019, p = 0.001; 2020, p = 0.006) were associated with block refusal. CONCLUSIONS: An established preoperative regional anesthesia program with blocks offered to all patients undergoing mastectomy with TE reconstruction can result in decreased racial disparities. However, continued differences in age, ethnicity, and insurance status justify future efforts to enhance preoperative educational efforts that address patient hesitancies in these subpopulations.

Early Complications in Prepectoral Tissue Expander-Based Breast Reconstruction.

BACKGROUND: Prepectoral implant placement for postmastectomy breast reconstruction has increased in recent years. Benefits of prepectoral reconstruction may include lack of animation deformities and reduced postoperative pain, but its complication profile is currently unclear. This study aimed to examine the complication profile of prepectoral tissue expanders (TEs) to determine factors associated with TE loss. METHODS: A retrospective review was performed to identify all patients who underwent immediate prepectoral TE reconstruction from January 2018 to June 2021. The decision to use the prepectoral technique was based on mastectomy skin quality and patient comorbidities. Patient demographics, comorbidities, and operative details were evaluated. Outcomes of interest included TE loss, seroma, hematoma, infection/cellulitis, mastectomy skin flap necrosis requiring revision, and TE exposure. Logistic regression analysis was performed to identify factors associated with TE loss. RESULTS: The study identified 1225 TEs. The most frequent complications were seroma (8.7%, n = 106), infection/cellulitis (8.2%, n = 101), and TE loss (4.2%, n = 51). Factors associated with TE loss in the univariate analysis included ethnicity, history of smoking, body mass index, mastectomy weight, and neoadjuvant chemotherapy. In the multivariate regression analysis, only mastectomy weight had a positive association with TE loss (odds ratio, 1.001; p = 0.016). CONCLUSION: Prepectoral two-stage breast reconstruction can be performed safely with an acceptable early complication profile. The study data suggest that increasing mastectomy weight is the most significant factor associated with TE loss. Further research examining the quality of the soft tissue envelope and assessing patient-reported outcomes would prove beneficial.

The evolution of pediatric soft-tissue free flap reconstruction of the lower extremity after oncologic resection: A 30 year experience.

INTRODUCTION: Limb salvage has become the standard of care for lower extremity tumors because of improvements in adjuvant treatments and reconstructive techniques. While there is literature assessing pediatric lower extremity free flap reconstruction in the setting of trauma, there is a paucity of literature that analyzes oncologic free flap reconstruction in this patient population. We report our long-term experience and evolution of care for lower extremity oncologic free flap reconstruction in pediatric patients. METHODS: This is a retrospective case series of all patients ≤18 years of age who underwent oncologic soft-tissue microvascular reconstruction of the lower extremity, from 1992 to 2021. Data were collected for patient demographics, oncologic treatment, operative details, and post-operative outcomes. Functional outcomes were assessed by weight bearing status, ambulation, and participation in activities-of-daily-living (ADLs), and musculoskeletal tumor society (MSTS) scores. RESULTS: Over the 30-year study period, inclusion criteria were met by 19 patients (11 males, 8 females) with a mean age of 13.8 years and a mean follow-up of 5.3 years. At last follow-up, 13 patients (68.5%) were alive. The most common pathology was osteogenic sarcoma (13 patients, 68.5%). Sites of reconstruction were the hip (n = 1), thigh (n = 5), knee (n = 4), leg (n = 7), and the foot (n = 2). The most commonly used flaps were latissimus dorsi (n = 8), gracilis (n = 4), and anterolateral thigh ± vastus (n = 4). Postoperative complications occurred in nine patients (43%). Overall flap success rate was 95%. At latest follow-up, ambulation without assistive device was obtained in 11 patients (58%), full weight bearing was achieved by 13 patients (68.5%), and ADLs could be performed independently by 13 patients (68.5%). Mean MSTS score was 23.1/30. CONCLUSION: Microvascular reconstruction for oncological lower extremity defects in the pediatric population has high limb salvage rates and good functional outcomes.

Comparisons of Impact of Vein Grafting with Different Indications on Outcomes of Reconstruction with Free Flaps.

BACKGROUND: Prior studies have shown an increased risk of complications and flap loss with the use of vein grafts in microsurgery. We hypothesize that indication for use of a vein graft can affect flap complications and loss rates. METHODS: We performed a retrospective review of all patients at our institution from 2010 to 2020 who underwent free flap reconstruction and required use of a vein graft. Indications for vein grafting included: salvage of flap during primary operation after microvascular compromise, augmentation of flow during primary operation, lengthening of the flap pedicle during the primary operation, and salvage of the flap during a secondary salvage operation after microvascular compromise. RESULTS: A total of 79 patients met the study inclusion criteria. There were significant differences among the vein graft indication groups and the following: area of reconstruction (p = 0.002), vein graft length (p = 0.018), vessels grafted (p = 0.001), vein graft donor site (p = 0.011), and total flap loss (p = 0.047). Of the four indications for vein grafting, salvage of the flap during secondary salvage operation after microvascular compromise had the highest rate of total flap loss (26.7%). There were no significant associations between other flap complications and vein graft indications. CONCLUSION: Vein graft use in the primary reconstructive setting is efficacious, with low risk of thrombosis. Use in secondary procedures, however, is associated with higher rates of total flap loss, likely due to the thrombotic process, which was initiated prior to the use of the graft resulting in the salvage procedure and not secondary to the graft itself.

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.

Efficacy of Immediate Lymphatic Reconstruction to Decrease Incidence of Breast Cancer-related Lymphedema: Preliminary Results of Randomized Controlled Trial.

OBJECTIVE: To conduct a randomized controlled trial (RCT) on the efficacy of immediate lymphatic reconstruction (ILR) for decreasing the incidence of breast cancer-related lymphedema (BCRL) after axillary lymph node dissection (ALND). BACKGROUND: Despite encouraging results in small studies, an appropriately powered RCT on ILR has not been performed. METHODS: Women undergoing ALND for breast cancer were randomized in the operating room 1:1 to either ILR, if technically feasible, or no ILR (control). The ILR group underwent lymphatic anastomosis to a regional vein using microsurgical techniques; control group had no repair and cut lymphatics were ligated. Relative volume change (RVC), bioimpedance, quality of life (QoL), and compression use were evaluated at baseline and every 6 months postoperatively up to 24 months. Indocyanine green (ICG) lymphography was performed at baseline and 12 and 24 months postoperatively. The primary outcome was the incidence of BCRL, defined as ≥10% RVC from baseline in the affected extremity at 12-, 18-, or 24-month follow-up. RESULTS: Of 72 patients randomized to ILR and 72 to control from January 2020 to March 2023, our preliminary analysis includes 99 patients with 12-month follow-up, 70 with 18-month follow-up, and 40 with 24-month follow-up. The cumulative incidence of BCRL was 9.5% in the ILR group and 32% in the control group ( P =0.014). The ILR group had lower bioimpedance values, decreased compression usage, better lymphatic function on ICG lymphography, and better QoL than the control group. CONCLUSIONS: Preliminary results of our RCT show that ILR after ALND decreases BCRL incidence. Our goal is to finish the accrual of 174 patients with 24-month follow-up.

The Impact of Psychiatric Diagnoses on Patient-reported Satisfaction and Quality of Life in Postmastectomy Breast Reconstruction.

OBJECTIVE: The purpose of this study was to determine the prevalence of psychiatric diagnoses among a sample of breast reconstruction patients and measure the association between these diagnoses and reconstruction-related, patient-reported outcomes. BACKGROUND: The impact of psychiatric disorders in conjunction with breast cancer diagnosis, treatment, and reconstruction have the potential to cause significant patient distress but remains not well understood. METHODS: A retrospective review of postmastectomy breast reconstruction patients from 2007 to 2018 at Memorial Sloan Kettering Cancer Center was conducted. Patient demographics, comorbidities, cancer characteristics, psychiatric diagnoses, and BREAST-Q Reconstruction Module scores (measuring satisfaction with breast, well-being of the chest, psychosocial, and sexual well-being) at postoperative years 1 to 3 were examined. Mixed-effects models and cross-sectional linear regressions were conducted to measure the effect of psychiatric diagnostic class type and number on scores. RESULTS: Of 7414 total patients, 50.1% had at least 1 psychiatric diagnosis. Patients with any psychiatric diagnoses before reconstruction had significantly lower BREAST-Q scores for all domains at all time points. Anxiety (50%) and depression (27.6%) disorders were the most prevalent and had the greatest impact on BREAST-Q scores. Patients with a greater number of psychiatric diagnostic classes had significantly worse patient-reported outcomes compared with patients with no psychiatric diagnosis. Psychosocial (ß: -7.29; 95% confidence interval: -8.67, -5.91), and sexual well-being (ß: -7.99; 95% confidence interval: -9.57, -6.40) were most sensitive to the impact of psychiatric diagnoses. CONCLUSIONS: Mental health status is associated with psychosocial and sexual well-being after breast reconstruction surgery as measured with the BREAST-Q. Future research will need to determine what interventions (eg, screening, early referral) can help improve outcomes for breast cancer patients with psychiatric disorders undergoing breast reconstruction.

Enhanced Surgical Decision-Making Tools in Breast Cancer: Predicting 2-Year Postoperative Physical, Sexual, and Psychosocial Well-Being following Mastectomy and Breast Reconstruction (INSPiRED 004).

BACKGROUND: We sought to predict clinically meaningful changes in physical, sexual, and psychosocial well-being for women undergoing cancer-related mastectomy and breast reconstruction 2 years after surgery using machine learning (ML) algorithms trained on clinical and patient-reported outcomes data. PATIENTS AND METHODS: We used data from women undergoing mastectomy and reconstruction at 11 study sites in North America to develop three distinct ML models. We used data of ten sites to predict clinically meaningful improvement or worsening by comparing pre-surgical scores with 2 year follow-up data measured by validated Breast-Q domains. We employed ten-fold cross-validation to train and test the algorithms, and then externally validated them using the 11th site's data. We considered area-under-the-receiver-operating-characteristics-curve (AUC) as the primary metric to evaluate performance. RESULTS: Overall, between 1454 and 1538 patients completed 2 year follow-up with data for physical, sexual, and psychosocial well-being. In the hold-out validation set, our ML algorithms were able to predict clinically significant changes in physical well-being (chest and upper body) (worsened: AUC range 0.69-0.70; improved: AUC range 0.81-0.82), sexual well-being (worsened: AUC range 0.76-0.77; improved: AUC range 0.74-0.76), and psychosocial well-being (worsened: AUC range 0.64-0.66; improved: AUC range 0.66-0.66). Baseline patient-reported outcome (PRO) variables showed the largest influence on model predictions. CONCLUSIONS: Machine learning can predict long-term individual PROs of patients undergoing postmastectomy breast reconstruction with acceptable accuracy. This may better help patients and clinicians make informed decisions regarding expected long-term effect of treatment, facilitate patient-centered care, and ultimately improve postoperative health-related quality of life.

Interpreting the BREAST-Q for Breast-Conserving Therapy: Minimal Important Differences and Clinical Reference Values.

BACKGROUND: The BREAST-Q is an important tool for evaluating patient satisfaction and quality of life in breast-conserving therapy (BCT) patients, but its clinical utility is limited by the lack of guidance on score interpretation. This study determines reference values and the minimal important difference (MID) for the BREAST-Q BCT module. METHODS: A retrospective review of BCT patients at Memorial Sloan Kettering Cancer Center from January 2011 to December 2021 was performed. Descriptive statistics were used to summarize median BREAST-Q scores. Distribution-based analyses estimated MIDs based on 0.2 standard deviation of baseline BREAST-Q scores and 0.2 standardized response mean of the difference between baseline and 1-year postoperative BREAST-Q scores. MIDs for different clinical groupings based on body mass index, radiation, and reexcision also were estimated. RESULTS: Overall, 8060 patients were included for determining reference values, and 5673 patients were included for estimating MIDs. Median BREAST-Q scores trended upwards and stabilized by 2 years after surgery for all domains except Physical Well-Being of the Chest, which decreased and stabilized by 2 years. A score interpretation tool, the Real-Time Engagement and Communication Tool, was created based on 25th percentile, median, and 75th percentile scores trajectories. All MID estimates ranged from 3 to 5 points; 4 points was determined to be appropriate for use in clinical practice and research. CONCLUSIONS: Reference values and MIDs are crucial to BREAST-Q score interpretation, which can lead to improved clinical evaluation and decision making and improved research methodology. Future research should validate this study's findings in different patient cohorts.

The Impact of Lymphedema on Patient-Reported Outcomes After Breast Reconstruction: A Preliminary Propensity Score-Matched Analysis.

BACKGROUND: Studies on the impact of secondary lymphedema on patient-reported satisfaction and quality of life following postmastectomy breast reconstruction are limited by their heterogeneity. We aimed to reduce heterogeneity in study sample populations and compare BREAST-Q Reconstruction Module scores of patients with lymphedema matched to patients without lymphedema. METHODS: We identified patients who underwent postmastectomy breast reconstruction from 2009 to 2017 and performed a propensity score-matched analysis to compare patient-reported outcomes of patients who developed lymphedema with those who did not. Matched covariates included age, body mass index, race/ethnicity, smoking history, radiation or chemotherapy exposure, postoperative infection, and reconstruction modality and laterality. Outcomes of interest were pre- and postoperative BREAST-Q scores for Satisfaction with Breasts, Physical Well-being of the Chest, Sexual Well-Being, and Psychosocial Well-Being; the minimal clinically important difference (MCID) was four points. RESULTS: Matched cohorts included 322 patients per group. Preoperative BREAST-Q scores did not differ between lymphedema and non-lymphedema matched cohorts. Postoperative BREAST-Q scores were significantly lower in lymphedema patients: Physical Well-Being of the Chest (all time points), Satisfaction with Breast (at 1 and 2 years), Sexual Well-Being (at 2 years), and Psychosocial Well-Being (at 2 and 3 years). All significant differences in average scores were greater than the MCID. CONCLUSIONS: Patients with breast cancer-related lymphedema reported significantly lower Physical Well-Being of the Chest, Satisfaction with Breasts, Sexual Well-Being, and Psychosocial Well-Being at various time points. Our findings may prove useful for patient counseling and justify the need for further research on the prevention and treatment of this devastating disease.

Strategies to avoid mastectomy skin-flap necrosis during nipple-sparing mastectomy.

BACKGROUND: Nipple-sparing mastectomy is associated with a higher risk of mastectomy skin-flap necrosis than conventional skin-sparing mastectomy. There are limited prospective data examining modifiable intraoperative factors that contribute to skin-flap necrosis after nipple-sparing mastectomy. METHODS: Data on consecutive patients undergoing nipple-sparing mastectomy between April 2018 and December 2020 were recorded prospectively. Relevant intraoperative variables were documented by both breast and plastic surgeons at the time of surgery. The presence and extent of nipple and/or skin-flap necrosis was documented at the first postoperative visit. Necrosis treatment and outcome was documented at 8-10 weeks after surgery. The association of clinical and intraoperative variables with nipple and skin-flap necrosis was analysed, and significant variables were included in a multivariable logistic regression analysis with backward selection. RESULTS: Some 299 patients underwent 515 nipple-sparing mastectomies (54.8 per cent (282 of 515) prophylactic, 45.2 per cent therapeutic). Overall, 23.3 per cent of breasts (120 of 515) developed nipple or skin-flap necrosis; 45.8 per cent of these (55 of 120) had nipple necrosis only. Among 120 breasts with necrosis, 22.5 per cent had superficial, 60.8 per cent had partial, and 16.7 per cent had full-thickness necrosis. On multivariable logistic regression analysis, significant modifiable intraoperative predictors of necrosis included sacrificing the second intercostal perforator (P = 0.006), greater tissue expander fill volume (P < 0.001), and non-lateral inframammary fold incision placement (P = 0.003). CONCLUSION: Modifiable intraoperative factors that may decrease the likelihood of necrosis after nipple-sparing mastectomy include incision placement in the lateral inframammary fold, preserving the second intercostal perforating vessel, and minimizing tissue expander fill volume.

Reducing opioid prescribing after ambulatory breast reconstruction surgery.

BACKGROUND: The lack of evidence-based guidelines for postoperative opioid prescriptions following breast reconstruction contributes to a wide variation in prescribing practices and increases potential for misuse and abuse. METHODS: Between August and December 2019, women who underwent outpatient breast reconstruction were surveyed 7-10 days before (n = 97) and after (n = 101) implementing a standardized opioid prescription reduction initiative. We compared postoperative opioid use, pain control, and refills in both groups. Patient reported outcomes were compared using the BREAST-Q physical wellbeing of the chest domain and a novel symptom Recovery Tracker. RESULTS: Before changes in prescriptions, patients were prescribed a median of 30 pills and consumed three pills (interquartile range [IQR: 1,9]). After standardization, patients were prescribed eight pills and consumed three pills (IQR: 1,6). There was no evidence of a difference in the proportion of patients experiencing moderate to very severe pain on the Recovery Tracker or in the early BREAST-Q physical wellbeing of the chest scores (p = 0.8 and 0.3, respectively). CONCLUSION: Standardizing and reducing opioid prescriptions for patients undergoing reconstructive breast surgery is feasible and can significantly decrease the number of excess pills prescribed. The was no adverse impact on early physical wellbeing, although larger studies are needed to obtain further data.

Reconstruction of oncologic upper extremity defects with fibula free flaps has high union rates and excellent functional outcomes.

BACKGROUND: Limb salvage has better functional outcomes than amputation in the upper extremity. This can however be challenging after bony tumor resections. METHODS: This is a retrospective case series of patients who underwent humerus, ulna, or radius reconstruction with a fibula free flap. Data were collected on demographics, oncologic history, surgical details, and complications. Functional outcome measures included the patient's ability to perform activities of daily living (ADL), presence of pain, and musculoskeletal tumor society (MSTS) score. RESULTS: Over a 25-year period, 38 reconstructions were performed. The flap success rate was 97.5%. Bony union was obtained in 19 of 19 (100%) forearm reconstructions and in 15 of 19 (79%) humerus reconstructions (p = 0.10). All 19 forearm reconstruction patients and 18/19 humerus reconstruction patients were able to perform ADLs with no pain or only occasional pain. The MSTS scores were not significantly different between the humerus and forearm cohorts (27.1 vs. 27.3, p = 0.68). Functional outcomes were significantly better in limbs that achieved union (p < 0.001). Recipient and donor site complications occurred in 10 (26.3%) and 5 (13%) patients, respectively. CONCLUSIONS: Oncologic upper-extremity reconstruction with fibula free flaps has excellent functional outcomes. Bone union is a predictor of superior limb function.

Decreasing length of stay in breast reconstruction patients: A national analysis of 2019-2020.

BACKGROUND: The effects of COVID-19 on breast reconstruction included shifts toward alloplastic reconstruction methods to preserve hospital resources and minimize COVID exposures. We examined the effects of COVID-19 on breast reconstruction hospital length of stay (LOS) and subsequent early postoperative complication rates. METHODS: Using the National Surgical Quality Improvement Program, we examined female patients who underwent mastectomy with immediate breast reconstruction from 2019 to 2020. We compared postoperative complications across 2019-2020 for alloplastic and autologous reconstruction patients. We further performed subanalysis of 2020 patients based on LOS. RESULTS: Both alloplastic and autologous reconstruction patients had shorter inpatient stays. Regarding the alloplastic 2019 versus 2020 cohorts, complication rates did not differ (p > 0.05 in all cases). Alloplastic patients in 2020 with longer LOS had more unplanned reoperations (p < 0.001). Regarding autologous patients in 2019 versus 2020, the only complication increasing from 2019 to 2020 was deep surgical site infection (SSI) (2.0% vs. 3.6%, p = 0.024). Autologous patients in 2020 with longer LOS had more unplanned reoperations (p = 0.007). CONCLUSIONS: In 2020, hospital LOS decreased for all breast reconstruction patients with no complication differences in alloplastic patients and a slight increase in SSIs in autologous patients. Shorter LOS may lead to improved satisfaction and lower healthcare costs with low complication risk, and future research should examine the potential relationship between LOS and these outcomes.

Moving towards patient-reported outcomes in routine clinical practice: implementation lessons from the BREAST-Q.

PURPOSE: Longitudinal, routine utilization of patient-reported outcome measures (PROMs) in clinical care has been challenging. The purpose of this study is to describe a quality improvement initiative to improve patient engagement with the BREAST-Q, a gold-standard PROM for breast reconstruction. METHODS: In 2011, we implemented the BREAST-Q as part of routine care. In 2018, we began a quality improvement initiative to increase BREAST-Q patient participation. The BREAST-Q was administered at every clinic visit via an institutional patient portal or an in-clinic tablet; digital dashboard technologies were used to improve workflow integration, real-time accountability, and immediate data availability at clinic visits. High clinical staff engagement was encouraged by assigning "BREAST-Q Champions." BREAST-Q completion data and patient characteristics were examined to understand non-response to the assessment. RESULTS: Following quality improvement, the average annual BREAST-Q completion rate increased from 42.8% in 2011-2017 to 87.6% in 2019, the last full year of our study period. High completion rates were maintained January-July 2020; however, a significantly larger proportion of BREAST-Qs were completed at home in 2020 versus the same period in 2019 (49.7 vs. 38.8%, p < 0.001), potentially due to the COVID-19 pandemic. Compared with non-responders, responders were younger (49.7 vs. 52.2 years, p < 0.001), more likely to be white (76.9 vs. 73.6%, p < 0.001), and had private insurance (79.4 vs. 69.8%, p < 0.001). CONCLUSION: Our quality improvement initiative successfully increased routine completion of the BREAST-Q. Similar implementation techniques may prove beneficial at other institutions interested in incorporating PROMs into routine care.

Outcomes and Perioperative Risk Factors after Oncologic Free-Flap Scalp Reconstruction.

BACKGROUND: Little is known about the risk factors associated with complications after free flap scalp reconstruction. The purpose of this study was to identify patient, scalp defect, and flap characteristics associated with increased risk of surgical complications. METHODS: A retrospective study was performed of free-flap scalp reconstruction in oncologic patients at Memorial Sloan Kettering Cancer Center from 2002 to 2017. Data collection included patient, defect, flap, and complication characteristics. Complications were classified into major, defined as complications requiring surgical intervention, and minor, defined as complications requiring conservative treatment. Risk factors and outcome variables were compared using chi-square with Fisher's exact test. RESULTS: A total of 63 free flaps to the scalp in 58 patients were performed; average follow-up was 3.5 years. Most flaps were muscle-only or musculocutaneous. One-third of patients with free flaps experienced complications (n = 21, 15 major and 6 minor). Examining risk factors for complications, patients with cardiovascular disease were nearly three times more likely to have suffered a major complication than patients without cardiovascular disease (36.7 vs. 12.1%, p = 0.04). This was the only significant risk factor noted. Perioperative radiotherapy, prior scalp surgery, flap type, and recipient vessel selection were found to be nonsignificant risk factors. CONCLUSION: Cardiovascular disease may be a significant marker of risk for major complications in patients undergoing free-flap reconstruction of the scalp. This information should be used to help guide perioperative counseling and decision making in this challenging patient population.

The Skin Necrosis Conundrum: Examining Long-term Outcomes and Risk Factors in Implant-Based Breast Reconstruction.

BACKGROUND: Mastectomy skin flap necrosis (MSFN) is a common complication following mastectomy that causes significant distress to patients and physicians and also compromises oncologic, surgical, and quality-of-life outcomes. OBJECTIVES: We sought to investigate the long-term outcomes of MSFN following implant-based reconstruction (IBR) and determine the rates and predictors of post-MSFN complications. METHODS: This was a 20-year analysis of consecutive adult (>18 years) patients who developed MSFN following mastectomy and IBR from January 2001 to January 2021. Multivariable analyses were performed to identify factors associated with post-MSFN complications. RESULTS: We identified 148 reconstructions, with a mean follow-up time of 86.6 ± 52.9 months. The mean time from reconstruction to MSFN was 13.3 ± 10.4 days, and most cases (n = 84, 56.8%) were full-thickness injuries. Most cases (63.5%) were severe, 14.9% were moderate, and 21.6% were mild. Forty-six percent (n = 68) developed a breast-related complication, with infection being the most common (24%). An independent predictor of overall complications was longer time from reconstruction to MSFN (odds ratio [OR], 1.66; P = .040). Aging was an independent predictor of overall complications (OR, 1.86; P = .038); infection (OR, 1.72; P = .005); and dehiscence (OR, 6.18; P = .037). Independent predictors of dehiscence were longer interval from reconstruction to MSFN (OR, 3.23; P = .018) and larger expander/implant size (OR, 1.49; P = .024). Independent predictors of explantation were larger expander/implant size (OR, 1.20; P = .006) and nipple-sparing mastectomy (OR, 5.61; P = .005). CONCLUSIONS: MSFN is associated with high risk of complications following IBR. Awareness of the timing and severity of MSFN and the predictors of post-MSFN complications is crucial for guiding evidence-based decision-making and improving outcomes.
