RESUMEN

BACKGROUND: The BREAST-Q real-time engagement and communication tool (REACT) was developed to aid with BREAST-Q score interpretation and guide patient-centered care. OBJECTIVE: The purpose of this qualitative study was to examine the perspectives of patients and providers on the design, functionality, and clinical utility of REACT and refine the REACT based on their recommendations. METHODS: We conducted three patient focus groups with women who were at least 6 postoperative months from their postmastectomy breast reconstruction, and two provider focus groups with plastic surgeons, breast surgeons, and advanced practice providers. Focus groups were audio-taped, transcribed verbatim, and analyzed thematically. RESULTS: A total of 18 breast reconstruction patients and 14 providers participated in the focus groups. Themes identified by thematic analysis were organized into two categories: (1) design and functionality, and (2) clinical utility. On the design and functionality of REACT, four major themes were identified: visual appeal and usefulness; contextualizing results; ability to normalize patients' experiences, noting participants' concerns; and suggested modifications. On the clinical utility of REACT, three major themes were identified: potential to empower patients to communicate with their providers; increase patient and provider motivation to engage with the BREAST-Q; and effective integration into clinical workflow. CONCLUSION: Patients and providers in this qualitative study indicated that with some modifications, REACT has a great potential to elevate the clinical utility of the BREAST-Q by enhancing patient-provider communication that can lead to patient-centered, clinically relevant action recommendations based on longitudinal BREAST-Q scores.

RESUMEN

BACKGROUND: This study aims to explore the ideal breast size by assessing the relationship between mastectomy to free flap weight ratio and complications as well as patient-reported outcomes in autologous breast reconstruction (ABR). METHOD: A retrospective review of patients undergoing bilateral immediate ABR with mastectomy and flap weights available was completed. Patients were divided into three groups based on the ratio of mastectomy to flap weights. The patients were grouped as "maintained" if the flap weight was within 10% of the mastectomy weight. Patients with a weight difference greater than 10% were used to declare "downsized" or "upsized." Outcomes included complications and four domains of the BREAST-Q at 1-year postoperatively. RESULTS: Three hundred and fifty-nine patients were included in the analysis, of which 112 were downsized, 91 maintained, and 156 upsized, respectively. Presence of complications did not significantly differ among the groups. At 1-year postoperatively, Sexual Well-being significantly differed (p = 0.033). Between preoperative and 1 year, patients who upsized experienced an improvement in Satisfaction with Breasts by 16 points (p < 0.001), while patients who downsized experienced a decline in Physical Well-being of the Chest by 7 points (p = 0.016). Multivariable linear regression model showed that Sexual Well-being was 13 points lower in the downsized cohort than in the maintained cohort (ß = -13, 95% confidence interval: -21 to -5.4; p = 0.001). CONCLUSION: Although complication rates do not significantly differ between the three cohorts, patients who downsize may have lower Sexual Well-being postoperatively. Surgeons should consider our preliminary findings to counsel patients preoperatively about the predicted breast size and the impact of downsizing on sexual health.

RESUMEN

BACKGROUND: There is a lack of literature of health-related quality of life endpoints for radial forearm (RF) versus anterolateral thigh (ALT) free flap reconstruction for glossectomy defects. Our goal was to perform a comprehensive evaluation of clinical, functional, and quality of life outcomes after glossectomy reconstruction using a RF or ALT flap. METHODS: A retrospective review was performed on patients who underwent glossectomy and immediate reconstruction with RF or ALT flaps between 2016 and 2021. Outcomes of interest included readmission and reoperation rates, functional assessments, tracheostomy and gastrostomy tube status, and FACE-Q Head and Neck Cancer scores. RESULTS: Seventy-eight patients consisting of 54 RF and 24 ALT free flaps were included. ALT patients had a larger median flap size (72 vs. 48 cm2 , p = 0.021) and underwent mandibulotomy (50% vs. 7.4%, p < 0.0001) and base of tongue resection (58.3% vs. 24.1%, p = 0.005) at higher rates. No significant differences were found with respect to other outcomes. CONCLUSION: The RF and ALT flaps are suitable for glossectomy reconstruction, with minimal differences seen in postoperative outcomes. Our study suggests that ALT can be used in patients with base of tongue and larger defect sizes, while providing similar functional and clinical outcomes to RF reconstruction.

RESUMEN

BACKGROUND: The choice of tissue type for free flap reconstruction of posterolateral mandible resections is dependent on patient and defect characteristics. We compared clinical and patient-reported outcomes following reconstruction of these defects with a soft tissue or bony free flap. METHODS: A retrospective review was performed on patients who underwent posterolateral segmental mandibulectomy with immediate free flap reconstruction at MSKCC from 2006 to 2021. Outcomes of interest were patient-reported outcome measures (PROMs) assessed by FACE-Q surveys and complications at the flap recipient site. RESULTS: Ninety patients received a bony flap and 24 patients received a soft tissue flap. Patients reconstructed with soft tissue flaps had greater rates of composite soft tissue defects (p < 0.0001), condyle resection (p = 0.001), and peripheral vascular disease (p = 0.035). Complication rates were similar between the cohorts (p > 0.05). Bony flaps scored higher on multiple FACE-Q scales: Facial Appearance (p = 0.023) Eating/Drinking (p = 0.029), Smiling (p = 0.012), Speaking (p < 0.001), Swallowing (p = 0.012), Smiling Distress (p = 0.037), and Speaking Distress (p = 0.001). CONCLUSION: Reconstruction of posterolateral mandibular defects has a similar complication profile when utilizing a bony or soft tissue free flap. Bony flaps may perform better with respect to PROMs. Reconstructive surgeons should consider using bony flap reconstruction to achieve higher patient satisfaction and quality of life.

RESUMEN

BACKGROUND: When abdomen-based free flap reconstruction is contraindicated, the muscle-sparing thoracodorsal artery perforator (TDAP) flap may be considered for total autologous breast reconstruction. The TDAP flap is often limited by volume and is prone to distal flap necrosis. We aim to demonstrate our experience combining the delay phenomenon with TDAP flaps for total autologous breast reconstruction. METHODS: Patients presenting for autologous breast reconstruction between April 2021 and August 2023 were recruited for surgically delayed TDAP flap reconstruction when abdominally based free flap reconstruction was contraindicated because of previous abdominal surgery or poor perforator anatomy. We dissected the TDAP flap except for a distal skin bridge and then reconstructed the breast 1 to 7 days later. Data included flap dimensions (in centimeters × centimeters), delay time (in days), predelay and postdelay perforator caliber (in millimeters) and flow (in centimeters per second), operative time (in minutes), hospital length of stay (in days), complications/revisions, and follow-up time (in days). RESULTS: Fourteen patients and 16 flaps were included in this study. Mean age and body mass index of patients were 55.9 ± 9.6 years and 30.1 ± 4.3 kg/m2, respectively. Average flap skin island length and width were 32.1 ± 3.3 cm (n = 8 flaps) and 8.8 ± 0.7 cm (n = 5 flaps), respectively. Beveled flap width reached 16.0 ± 2.2 cm (n = 3 flaps). Average time between surgical delay and reconstruction was 2.9 days, ranging from 1 to 7 days (n = 18 flaps). Mean predelay and postdelay TDAP vessel caliber and flow measured by Doppler ultrasound increased from 1.4 ± 0.3 to 1.8 ± 0.3 mm (P = 0.03) and 13.3 ± 5.2 to 43.4 ± 18.8 cm/s (P = 0.03), respectively (n = 4 flaps). Complications included 1 donor site seroma and 1 mastectomy skin flap necrosis. Follow-up ranged from 4 to 476 days (n = 17 operations). CONCLUSIONS: We demonstrate surgically delayed TDAP flaps as a viable option for total autologous breast reconstruction. Our series of flaps demonstrated increased perforator caliber and flow and enlarged volume capabilities and had no incidences of flap necrosis.

RESUMEN

BACKGROUND: Hourly flap checks are the most common means of flap monitoring during the first 24 hours following autologous breast reconstruction (ABR). This practice often requires intensive care unit (ICU) admission, which is a key driver of health care costs and decreased patient satisfaction. This study addresses these issues by demonstrating decreased cost and length of admission associated with a 4-hour interval between flap checks during the first 24 hours following ABR. METHODS: This is a retrospective review of ABR surgeries performed by multiple surgeons from 2017 to 2020. Two cohorts were identified, one that underwent flap checks every hour in the ICU (Q1 cohort) and the other that underwent flap checks every 4 hours on the hospital floor (Q4 cohort). Our primary outcome measures were length of stay (LOS), flap takebacks, flap loss, and encounter cost. RESULTS: Rates of flap takeback and loss did not differ between cohorts (P = 0.18, P = 0.21). The Q4 cohort's average LOS was shorter than the Q1 cohort (P = 0.002). The Q4 cohort's average cost was also $25,554.80 less than the Q1 cohort (P < 0.001). This association persisted after controlling for LOS, operating room takeback, timing and laterality of reconstruction, and flap configuration (hazard ratio = 0.65, P = 0.0007). CONCLUSION: This study demonstrates the benefits of lengthened flap check intervals during the first 24 hours following ABR. These intervals decrease the cost of ABR while also maintaining safety, making ABR a more accessible option for breast reconstruction patients.

RESUMEN

BACKGROUND: Fibula free flaps (FFF) are the gold standard tissue for the reconstruction of segmental mandibular defects. A comparison of miniplate (MP) and reconstruction bar (RB)-based fixation of FFFs has been previously described in a systematic review; however, long-term, single-center studies comparing the two plating methods are lacking. The authors aim to examine the complication profile between MPs and RBs at a single tertiary cancer center. We hypothesized that increased components and a lack of rigid fixation inherent to MPs would lead to higher rates of hardware exposure/failure. METHODS: A retrospective review was performed from a prospectively maintained database at Memorial Sloan Kettering Cancer Center. All patients who underwent FFF-based reconstruction of mandibular defects between 2015 and 2021 were included. Data on patient demographics, medical risk factors, operative indications, and chemoradiation were collected. The primary outcomes of interest were perioperative flap-related complications, long-term union rates, osteoradionecrosis (ORN), return to the operating room (OR), and hardware exposure/failure. Recipient site complications were further stratified into two groups: early (<90 days) and late (>90 days). RESULTS: In total, 96 patients met the inclusion criteria (RB = 63, MP = 33). Patients in both groups were similar with respect to age, presence of comorbidities, smoking history, and operative characteristics. The mean follow-up period was 17.24 months. In total, 60.6 and 54.0% of patients in the MP and RB cohorts received adjuvant radiation, respectively. There were no differences in rates of hardware failure overall; however, in patients with an initial complication after 90 days, MPs had significantly higher rates of hardware exposure (3 vs. 0, p = 0.046). CONCLUSION: MPs were found to have a higher risk of exposed hardware in patients with a late initial recipient site complication. It is possible that improved fixation with highly adaptive RBs designed by computer-aided design/manufacturing technology explains these results. Future studies are needed to assess the effects of rigid mandibular fixation on patient-reported outcome measures in this unique population.

RESUMEN

BACKGROUND: A comprehensive understanding of changes in health-related quality of life after head and neck cancer surgery is necessary for effective preoperative counseling. The goal of this study was to perform a longitudinal analysis of postoperative quality of life outcomes after fibula free flap (FFF) mandible reconstruction. METHODS: A retrospective review was performed for all patients who underwent oncologic mandible reconstruction with an FFF between 2000 and 2021. Completion of at least one postoperative FACE-Q questionnaire was necessary for inclusion. FACE-Q scores were divided into five time periods for analysis. Functional outcomes measured with speech language pathology (SLP) assessments and tracheostomy and gastrostomy tube status were analyzed at three time points. RESULTS: One hundred and nine patients were included. Of these, 68 patients also had at least one SLP assessment. All outcomes as measured by the various FACE-Q scales did not improve significantly from the immediate postoperative time point to the last evaluated time point (p > 0.05). SLP functional outcomes showed some deterioration over time, but these were not significant (p > 0.05). The percentage of patients who required a tracheostomy (18 to 2%, p = 0.002) or gastrostomy tube (25 to 11%, p = 0.035) decreased significantly from the immediate postoperative time point to the last evaluated time point. CONCLUSION: Subjective quality of life outcomes do not change significantly with time after oncologic FFF mandible reconstruction. Reconstructive surgeons can use these results to help patients establish appropriate and achievable quality of life goals after surgery. Further studies are warranted to elucidate the impact of specific relevant clinical variables on postoperative quality of life.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Clouds substantially affect Earth's energy budget by reflecting solar radiation back to space and by restricting emission of thermal radiation to space. They are perhaps the largest uncertainty in our understanding of climate change, owing to disagreement among climate models and observational datasets over what cloud changes have occurred during recent decades and will occur in response to global warming. This is because observational systems originally designed for monitoring weather have lacked sufficient stability to detect cloud changes reliably over decades unless they have been corrected to remove artefacts. Here we show that several independent, empirically corrected satellite records exhibit large-scale patterns of cloud change between the 1980s and the 2000s that are similar to those produced by model simulations of climate with recent historical external radiative forcing. Observed and simulated cloud change patterns are consistent with poleward retreat of mid-latitude storm tracks, expansion of subtropical dry zones, and increasing height of the highest cloud tops at all latitudes. The primary drivers of these cloud changes appear to be increasing greenhouse gas concentrations and a recovery from volcanic radiative cooling. These results indicate that the cloud changes most consistently predicted by global climate models are currently occurring in nature.

RESUMEN

BACKGROUND: The superficial inferior epigastric artery (SIEA) flap allows transfer of tissue without violating the rectus fascia. Traditionally it is best used in single stage reconstruction when vessel caliber is 1.5 mm; 56% to 70% of SIEAs are less than 1.5 mm and, therefore, not reliable. We aim to demonstrate the increased reliability of SIEA through surgical delay by quantifying reconstructive outcomes and delay-induced hemodynamic alterations. METHODS: Patients presenting for autologous breast reconstruction between May 2019 and October 2020 were evaluated with preoperative imaging and received either delayed SIEA or delayed deep inferior epigastric (DIEP) reconstruction based on clinical considerations, such as prior surgery and perforator size/location. Prospective data were collected on operative time, length of stay, and complications. Arterial diameter and peak flow were quantified with Doppler ultrasound predelay and postdelay. RESULTS: Seventeen delayed SIEA flaps were included. The mean age (± SD) was 46.2 ± 10.55 years, and body mass index was 26.7 ± 4.26 kg/m2. Average hospital stay after delay was 0.85 ± 0.90 days, and duration before reconstruction was 6 days to 14.5 months. Delay complications included 1 abdominal seroma (n = 1, 7.7%). Superficial inferior epigastric artery diameter predelay (mean ± 95% confidence interval) was 1.37 ± 0.20 mm and increased to 2.26 ± 0.24 mm postdelay. A significant increase in diameter was noted 0.9 ± 0.22 mm (P < 0.0001). Mean peak flow predelay was 14.43 ± 13.38 cm/s and 44.61 ± 60.35 cm/s (n = 4, P = 0.1822) postdelay. CONCLUSIONS: Surgical delay of the SIEA flap augments SIEA diameter, increasing the reliability of this flap for breast reconstruction. Superficial inferior epigastric artery delay results in low rates of complications and no failures in our series. Although more patients are needed to assess increase in arterial flow, use of surgical delay can expand the use of SIEA flap reconstruction and reduce abdominal morbidity associated with abdominal flap breast reconstruction.

RESUMEN

BACKGROUND: Radiation-associated soft tissue injury is a potentially devastating complication for head and neck cancer patients. The damage can range from minor sequelae such as xerostomia, which requires frequent daily maintenance, to destructive degenerative processes such as osteoradionecrosis, which can contribute to flap failure and delay or reverse oral rehabilitation. Despite the need for effective radioprotectants, the literature remains sparse, primarily focused on interventions beyond the surgeon's control, such as maintenance of good oral hygiene or modulation of radiation dose. METHODS: This narrative review aggregates and explores noninvasive, systemic treatment modalities for prevention or amelioration of radiation-associated soft tissue injury. RESULTS: We highlighted nine modalities with the most clinical potential, which include amifostine, melatonin, palifermin, hyperbaric oxygen therapy, photobiomodulation, pentoxifylline-tocopherol-clodronate, pravastatin, transforming growth factor-ß modulators, and deferoxamine, and reviewed the benefits and limitations of each modality. Unfortunately, none of these modalities are supported by strong evidence for prophylaxis against radiation-associated soft tissue injury. CONCLUSION: While we cannot endorse any of these nine modalities for immediate clinical use, they may prove fruitful areas for further investigation.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Obesity is a significant public health concern and clear risk factor for complications following breast reconstruction. To date, few have assessed patient-reported outcomes (PROs) focused on this key determinant. OBJECTIVE: Our study aimed to investigate the impact of obesity (body mass index ≥ 30) on postoperative satisfaction and physical function utilizing the BREAST-Q in a cohort of autologous breast reconstruction patients. METHODS: An Institutional Review Board-approved prospective investigation was conducted to evaluate PROs in patients undergoing autologous breast reconstruction from 2009 to 2017 at a tertiary academic medical center. The BREAST-Q reconstruction module was used to assess outcomes between cohorts preoperatively and at 6 months, 1 year, 2 years, and 3 years after reconstruction. RESULTS: Overall, 404 patients underwent autologous breast reconstruction with abdominal free-tissue transfer (244 non-obese, 160 obese) and completed the BREAST-Q. Although obese patients demonstrated lower satisfaction with breasts preoperatively (p = 0.04), no significant differences were noted postoperatively (p = 0.58). However, physical well-being of the abdomen was lower in the obese cohort compared with their non-obese counterparts at long-term follow-up (3 years; p = 0.04). CONCLUSION: Obesity significantly impacts autologous breast reconstruction patients. Although obese patients are more likely to present with dissatisfaction with breasts preoperatively, they exhibit comparable PROs overall compared with their non-obese counterparts, despite increased complications.

RESUMEN

OBJECTIVE: To better understand the long-term patient-reported outcomes (PROs) in satisfaction and health-related quality of life (QOL) following post-mastectomy reconstruction (PMR) using the BREAST-Q, comparing PROs from patients undergoing implant-based breast reconstruction (IBR) or autologous breast reconstruction (ABR). SUMMARY OF BACKGROUND DATA: Multiple studies have demonstrated growth in mastectomy rates and concurrent increase in PMR utilization. However, most studies examining PMR PROs focus on short postoperative time periods-mainly within 2 years. METHODS: BREAST-Q scores from IBR or ABR patients at a tertiary center were prospectively collected from 2009 to 2017. Mean scores and standard deviations (SDs) were calculated for satisfaction with breast, satisfaction with outcome, psychosocial well-being, physical well-being of the chest, and sexual well-being. Satisfaction with breasts and physical well-being of the chest were compared using regression models at postoperative years 1, 3, 5, and 7. RESULTS: Overall, 3268 patients were included, with 336 undergoing ABR and 2932 undergoing IBR. Regression analysis demonstrated that ABR patients had greater postoperative satisfaction with breast scores at all timepoints compared with IBR patients. Postoperative radiation and mental illness adversely impacted satisfaction with breast scores. Furthermore, mental illness impacted physical wellbeing of the chest at all timepoints. IBR patients had satisfaction scores that remained stable over the study period. CONCLUSION: This study presents the largest prospective examination of PROs in PMR to date. Patients who opted for ABR had significantly higher satisfaction with their breast and QOL at each assessed time point, but IBR patients had stable long-term satisfaction and QOL postoperatively.
