RESUMO
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.

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.

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.

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.

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.

ABSTRACT: Given that the use of breast implants for both cosmetic and reconstructive purposes is growing in the United States, an evaluation of factors that may affect the outcome of breast implant surgery is needed. A systematic review was conducted to evaluate the question: Does a personal or family history of autoimmune disease affect outcomes in breast implant surgery? The literature search yielded 2425 records, but after removal of duplicates, abstract screening, and full-text assessment, only 2 studies met the inclusion criteria for the final review. Both studies provided level III evidence and the average Methodological Index for Non-Randomized Studies score was 16.5 (range, 15-18 of 24), indicating a fair level of evidence overall. This systematic review found no evidence to support that a diagnosis of an autoimmune disease and/or a family history of autoimmune diseases will lead to poor surgical outcomes in breast implant surgery. Further study is warranted.

BACKGROUND: Acellular dermal matrix (ADM) is frequently utilized in prepectoral breast reconstruction, but few studies have examined the role of ADM type in complication risk. OBJECTIVES: This study was performed to determine the impact of ADM type on early complication rates in 2-stage alloplastic prepectoral breast reconstruction. METHODS: We performed a cohort examination of all patients who underwent mastectomy with immediate 2-stage alloplastic prepectoral breast reconstruction with ADM support at Memorial Sloan Kettering Cancer Center from 2018 to 2021. ADM types utilized included AlloDerm (LifeCell Corporation, Branchburg, NJ), FlexHD (MTF Biologics, Edison, NJ), and SurgiMend (Integra LifeSciences Corporation, Princeton, NJ). Complication rates based on the number of tissue expanders (TEs) were determined for each ADM type. Performance of multivariate logistic regression determined the impact of ADM type on complication risk after accounting for confounders. RESULTS: Overall, 726 patients (1054 TEs: 194 AlloDerm, 93 FlexHD, 767 SurgiMend) were included. The 3 cohorts differed in terms of mastectomy type (nipple-sparing: 23.5% of AlloDerm, 33.3% of FlexHD, 19.1% of SurgiMend, P = .038); ADM perforation (perforated: 94.8% of AlloDerm, 98.2% of FlexHD, 100% of SurgiMend, P < .001); and ADM size (AlloDerm: 153.2 cm2 [37.6], SurgiMend: 198.7 cm2 [10.4], FlexHD: 223.7 cm2 [37.9], P < .001). On univariate examination, no differences existed between ADM types for seroma, infection, exposure, malposition, or TE loss. Additionally, after adjustment for confounders with multivariate regression, no ADM type had higher odds of TE loss. CONCLUSIONS: In this large cohort of prepectoral reconstruction patients, ADM type did not significantly affect the risk of complications. Additional prospective studies are warranted to better evaluate ADM choice for prepectoral breast reconstruction.

PURPOSE: While vascularized lymph node transplant (VLNT) has gained popularity, there are a lack of prospective long-term studies and standardized outcomes. The purpose of this study was to evaluate the safety and efficacy of VLNT using all available outcome measures. METHODS: This was a prospective study on all consecutive patients who underwent VLNT. Outcomes were assessed with 2 patient-reported outcome metrics, limb volume, bioimpedance, need for compression, and incidence of cellulitis. RESULTS: There were 89 patients with the following donor sites: omentum (73%), axilla (13%), supraclavicular (7%), groin (3.5%). The mean follow-up was 23.7±12 months. There was a significant improvement at 2 years postoperatively across all outcome measures: 28.4% improvement in the Lymphedema Life Impact Scale, 20% average reduction in limb volume, 27.5% improvement in bioimpedance score, 93% reduction in cellulitis, and 34% of patients no longer required compression. Complications were transient and low without any donor site lymphedema. CONCLUSIONS: VLNT is a safe and effective treatment for lymphedema with significant benefits fully manifesting at 2 years postoperatively. Omentum does not have any donor site lymphedema risk making it an attractive first choice.

INTRODUCTION: Breast cancer-related lymphedema occurs in up to 30% of women following axillary lymph node dissection (ALND) and less commonly following sentinel lymph node biopsy. To quantify disability in these patients, patient-reported outcome measures (PROMs) have proven useful; however, given the overlap of symptoms between ALND and lymphedema, examination of their accuracy, sensitivity, and specificity in detecting lymphedema in breast cancer patients undergoing ALND is needed. METHODS: The Lymphedema Life Impact Scale (LLIS) and the Upper Limb Lymphedema 27 scale (ULL27) were administered to patients who had undergone ALND at least 2 years prior and either did or did not develop lymphedema. Survey responses and the degree of disability were compared to generate receiver operator characteristic (ROC) curves, and the sensitivity and specificity of PROMs to diagnose lymphedema were analyzed. RESULTS: Both PROMs were highly accurate, sensitive, and specific for detecting lymphedema. The LLIS had an accuracy of 97%, sensitivity of 100%, and specificity of 84.8% at a cutoff of ≥ 5.88 overall percent impairment score (higher scores indicate worse disability). The ULL27 had an accuracy of 93%, sensitivity of 88.6%, and specificity of 90.9% at a cutoff of ≤ 83.3 global score (lower scores indicate worse disability). CONCLUSIONS: The LLIS and the ULL27 appear to be highly specific for lymphedema and capable of differentiating it from symptoms resulting from ALND alone. Our findings suggest that use of these questionnaires with a threshold may be effective for diagnosing lymphedema, potentially reducing the need for frequent clinic visits and time-consuming measurements.

BACKGROUND: Comparisons of autologous breast reconstruction (ABR) and implant-based breast reconstruction (IBR) involve unavoidable confounders, which are often adjusted for in post hoc regression analyses. This study compared patient-reported outcomes between ABR patients and IBR patients by using propensity score matching to control for confounding variables upfront. METHODS: Propensity score matching analysis (2:1 nearest-neighbor matching with replacement) was performed for patients who underwent ABR or IBR without radiotherapy. Matched covariates included age, body mass index, history of psychiatric diagnosis, race-ethnicity, smoking status, and laterality of reconstruction. Outcomes of interest were BREAST-Q questionnaire scores for breast satisfaction and well-being. RESULTS: Of the 2334 patients identified, 427 were included in the final analysis: 159 who underwent ABR and 268 who underwent IBR. The ABR group matched the IBR group in the selected characteristics. ABR patients did not differ significantly from IBR patients in breast satisfaction or well-being at either 1 or 2 years after reconstructive surgery. CONCLUSIONS: This preliminary analysis of immediate breast reconstruction patients not requiring radiation therapy with similar propensities for ABR or IBR suggests comparable levels of breast satisfaction and well-being within 2 years after reconstructive surgery. Further research is needed with larger sample sizes, statistical power, and follow-up to better understand patient reported outcomes in this population, as the current findings differ from studies where patients were not matched on baseline characteristics.

BACKGROUND: Although rates of microvascular thrombosis following free-flap breast reconstruction are low, debate persists about the optimal methods to restore blood flow and prevent ensuing flap shrinkage or fibrosis. Here we evaluate our management of microvascular compromise, including both a review of our approach for restoring blood flow and addressing the ensuing inflammatory changes following ischemia reperfusion. METHODS: We conducted a retrospective review of autologous free tissue transfer breast reconstructions from 1/2010 to 1/2020. Patients who had flaps requiring take-back for salvage were identified. Management of microvascular compromise and ischemia reperfusion injury were recorded. RESULTS: Of 2103 flaps were used in the breast reconstructions, 47 flaps required take-back for microvascular compromise (2.2%). Most flaps were either completely salvaged (n = 29, 61.7%) or partially salvaged (n = 5, 10.6%). Thirteen (27.7%) were a total flap loss, for an overall rate of 0.8% (including 3 flaps with no salvage attempt). Management of microvascular compromise most often included revision of the anastomosis (n = 33, 70.2%), thrombectomy (n = 27, 57.4%), tissue plasminogen activator administration (n = 26, 55.3%), and vein grafts (n = 18, 38.3%). Management of ischemia reperfusion included intraoperative steroids (n = 33, 70.2%), postoperative steroids (n = 17, 38.6%), and postoperative therapeutic anticoagulation (n = 27, 61.3%). Of 34 salvaged flaps, 5 (14.7%) had partial flap loss and/or fat necrosis on clinical examination at an average follow-up of 2.7 ± 2.8 years. CONCLUSIONS: Salvage of microvascular compromise in autologous breast reconstruction should include restoration of blood flow and management of ischemia reperfusion injury. Attention to both is paramount for successful outcomes.

BACKGROUND: Lymphedema is a chronic and debilitating condition that affects many cancer survivors. Patient-reported outcome measures (PROMs) can give valuable insight into the impact of lymphedema on a patient's quality of life and can play an essential role in treatment decisions. This study aims to (1) identify PROMs used to assess health-related quality of life (HRQoL) in patients with lymphedema; and (2) assess the quality of the lymphedema-specific PROMs. METHODS: We performed a systematic search to identify articles on lymphedema, quality of life, and PROMs. An overview was created of all PROMs used to assess HRQoL in patients with lymphedema. The methodological quality of the lymphedema-specific PROMs was assessed using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) criteria. RESULTS: A total of 235 articles met the inclusion criteria, of which 200 described studies using one or more PROMs as an outcome measure in patients with lymphedema. The other 35 studies described the development and/or validation of a lymphedema-specific PROM. The COSMIN assessment demonstrated that none of these PROMs met all quality standards for development. CONCLUSION: The use of PROMs in lymphedema is increasing; however, based on our findings, we cannot fully support the use of any of the existing instruments. A well-developed lymphedema-specific PROM, based on patient input, is needed to gain better insight into the impact of this condition, and can be used to measure the effect of possible medical and surgical treatments.

BACKGROUND: The response to the unprecedented opioid crisis in the US has increased focus on multimodal pain regimens and enhanced recovery after surgery (ERAS) pathways to reduce opioid use. This study aimed to define patient and system-level factors related to perioperative consumption of opioids in autologous free-flap breast reconstruction. METHODS: We conducted a retrospective study to identify patients who underwent autologous breast reconstruction between 2010 and 2016. A multivariate linear regression model was developed to assess patient and system-level factors influencing opioid consumption. Opioid consumption was then dichotomized as total postoperative opioid consumption above (high) and below (low) the 50th percentile to afford more in-depth interpretation of the regression analysis. Secondary outcome analyses examined postoperative complications and health-related quality-of-life outcomes using the BREAST-Q. RESULTS: Overall, 601 patients were included in the analysis. Unilateral reconstruction, lower body mass index, older age, and administration of ketorolac and liposomal bupivacaine were associated with lower postoperative opioid consumption. In contrast, history of psychiatric diagnoses was associated with higher postoperative opioid consumption. There was no difference in the rates of postoperative complications when comparing the groups, although patients who had lower postoperative opioid consumption had higher BREAST-Q physical well-being scores. CONCLUSION: System-level components of ERAS pathways may reduce opioid use following autologous breast reconstruction, but surgical and patient factors may increase opioid requirements in certain patients. ERAS programs including liposomal bupivacaine and ketorolac should be established on a system level in conjunction with continued focus on individualized care, particularly for patients at risk for high opioid consumption.

OBJECTIVE: This study sought to estimate the incidence and incidence rate of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) at a high-volume single institution, which enables vigorous long-term follow-up and implant tracking for more accurate estimates. SUMMARY BACKGROUND DATA: The reported incidence of BIA-ALCL is highly variable, ranging from 1 in 355 to 1 in 30,000 patients, demonstrating a need for more accurate estimates. METHODS: All patients who underwent implant-based breast reconstruction from 1991 to 2017 were retrospectively identified. The incidence and incidence rate of BIA-ALCL were estimated per patient and per implant. A time-to-event analysis was performed using the Kaplan-Meier estimator and life table. RESULTS: During the 26-year study period, 9373 patients underwent reconstruction with 16,065 implants, of which 9589 (59.7%) were textured. Eleven patients were diagnosed with BIA-ALCL, all of whom had a history of textured implants. The overall incidence of BIA-ALCL was 1.79 per 1000 patients (1 in 559) with textured implants and 1.15 per 1000 textured implants (1 in 871), with a median time to diagnosis of 10.3 years (range, 6.4-15.5 yrs). Time-to-event analysis demonstrated a BIA-ALCL cumulative incidence of 0 at up to 6 years, increasing to 4.4 per 1000 patients at 10 to 12 years and 9.4 per 1000 patients at 14 to 16 years, although a sensitivity analysis showed loss to follow-up may have skewed these estimates. CONCLUSIONS: BIA-ALCL incidence and incidence rates may be higher than previous epidemiological estimates, with incidence increasing over time, particularly in patients exposed to textured implants for longer than 10 years.

BACKGROUND AND OBJECTIVE: Vascularized omentum lymphatic transplant (VOLT) for treatment of lymphedema has become popular because of no risk of iatrogenic lymphedema and abundant lymphatic tissue. However, perfusion to the omentum can be difficult to assess clinically. The purpose of this study was to clarify the incidence and degree of ischemia in the omentum. METHODS: A retrospective study was conducted to review indocyanine green perfusion findings on patients undergoing VOLT. Patients were placed into 4 categories based on the percentage surface area of omentum that was ischemic: normal, less than 25%, between 25% and 50%, and greater than 50% ischemic. Spearman correlation was performed to determine whether an association exists between prior abdominal surgery and the presence of ischemia. RESULTS: Twenty-six patients underwent VOLT for treatment of extremity lymphedema. Twelve (46.2%) patients had normal perfusion, 8 patients (30.8%) had less than 25% ischemia, and 6 patients (23.1%) had 25% to 50% ischemia. Prior abdominal surgery was not significantly associated with the presence of ischemia. CONCLUSIONS: Normal flap perfusion is a requisite for successful VOLT harvest. However, over half the patients had some degree of abnormal perfusion irrespective of prior abdominal surgery. Indocyanine green angiography is an important tool in ensuring a healthy lymphatic reconstruction.
