RESUMO

INTRODUCTION: National Institute of Health (NIH) funding is a "gold-standard" of achievement; we examined trends in NIH-funded pediatric surgeons. METHODS: NIH Research Portfolio Online Reporting Tools (RePORT) was queried for American Pediatric Surgical Association (APSA) members (2012 vs 2022). Demographics and time-to-award (TTA) from fellowship were compared. Number of grants, funding allotment, award classification, administering institutes/centers, research type were studied. RESULTS: Thirty-eight (4.6%) APSA members were NIH-funded in 2012 compared to 37 (2.9%) in 2022. Of funded surgeons in 2022, 27% were repeat awardees from 2012. TTA was similar (12 vs 14years, p=0.109). At each point, awards were commonly R01 grants (40 vs 52%, p â€‹= â€‹0.087) and basic science-related (76 vs 63%, p = â€‹0.179). Awardees were predominantly men (82% in 2012 vs 78% in 2022, p=0.779) and White (82% in 2012 vs 76% in 2022, p=0.586). Median amount per grant increased: $254,980 (2012) to $364,025 (2022); by $96,711 for men and $390,911 for women. Median awards for White surgeons increased by $215,699 (p=0.035), and decreased by $30,074 for non-White surgeons, though not significantly (p=0.368). CONCLUSION: The landscape of NIH-funded pediatric surgeons has remained unchanged between time points. With a substantial number of repeat awardees, predominance of R01 grants, and a median TTA over a decade after fellowship graduation, the phenotypes of early career pediatric surgeon-scientists are facing academic endangerment.

RESUMO

PURPOSE: Holistic review (HR) considers applicants' unique identities and experiences rather than focusing on academic metrics. Though several residency programs have demonstrated increases in women and those underrepresented in medicine (URiM), this is the first study to examine HR in pediatric surgery (PS). METHODS: Using a retrospective review of applicants, demographic, academic, and non-academic metrics of traditional review (TR) [2015-2017] were compared to HR [2018-2022]. HR initiatives include expansion of faculty reviewers, implementation of a pre-screening rubric, and greater prioritization of non-academic factors. Chi-squared/Fisher's exact tests, Wilcoxon rank-sum tests, and two sample z-test for proportions were used where appropriate. RESULTS: For 635 applicants (TR: 268, HR: 367), the proportion offered interviews in the TR and HR cohorts were similar (31.7 vs 36%, p = 0.30). Candidates selected for interview pre- and post-HR most commonly graduated from residency programs affiliated with PS fellowships (56.5 vs 50%, p = 0.65). After HR implementation, no change in proportion of women interviewees (TR: 52.9 vs HR: 54.5%, p = 0.93) was observed. Though URiM residents applying to PS remained consistently low (TR: 14.6 vs HR: 10.9%, p = 0.21), significantly more received interviews with HR (30.8 vs 42.5%, p = 0.001). The median number of peer-review publications per interviewee increased (17 vs 22, p = 0.02) as did non-academic achievements (leadership, service, athletic awards, etc.) per applicant (1.0 vs 1.5, p = 0.104), though the latter did not reach significance, demonstrating similar qualification of interviewees in HR and TR. CONCLUSION: Holistic review of PS fellowship applications increased the proportion of URiM interviewees, despite a persistently low URiM proportion in the applicant pool. Furthermore, implementing HR did not sacrifice the caliber of interviewees, as publications and non-academic achievements increased by over 25% in the HR cohort. LEVEL OF EVIDENCE: IV.

RESUMO

INTRODUCTION: In complex pediatric surgical oncology, surgical planning is contingent upon data gathered from preoperative imaging. Three-dimensional (3D) modeling and printing has been shown to be beneficial for adult presurgical planning, though pediatric literature is less robust. The study reviews our institutional experience with the use of 3D image segmentation and printed models in approaching resection of extracranial solid tumors in children. METHODS: This is a single institutional series from 2021 to 2023. Models were based on computed tomography and magnetic resonance imaging studies, optimized for 3D imaging. The feasibility and creation of the models is reviewed, including specific techniques, software, and printing materials from our institution. Clinical implications for surgical planning are also described, along with detailed preoperative and intraoperative images. RESULTS: 3D modeling and printing was performed for four pediatric patients diagnosed with extracranial solid tumors. Diagnoses included Ewing sarcoma, hepatoblastoma, synovial sarcoma, and osteosarcoma. No intraoperative complications or discrepancies with the preoperative 3D-printed model were noted. No evidence of local recurrence was identified in any patient thus far. CONCLUSION: Our institutional series demonstrates a wide spectrum of clinical application for 3D modeling and printing technology within pediatric surgical oncology. This technology may aid in surgical planning for both resection and reconstruction, can be applied to a diverse breadth of diagnoses, and may potentially augment patient and/or family education about their condition.

RESUMO

Colorectal cancer (CRC) is a major public health concern and disproportionately impacts racial/ethnic minority populations in the US. Animal models are helpful in examining human health disparities because many stress-induced human health conditions can be recapitulated using mouse models. Azoxymethane (AOM)/ dextran sodium sulfate (DSS) treatment can be used to model colitis-associated cancers. While colitis-associated cancers account for only 2% of colon cancers, the AOM/DSS model is useful for examining links between inflammation, immunity, and colon cancer. Mice were housed in enriched and impoverished environments for 1-month prior to behavioral testing. Following behavioral testing the mice were subjected to the AOM/DSS model. While our analysis revealed no significant behavioral variances between the impoverished and enriched housing conditions, we found significant effects in tumorigenesis. Enriched mice had fewer tumors and smaller tumor volumes compared to impoverished mice. African Americans are at higher risk for early onset colorectal cancers in part due to social economic status. Furthermore, housing conditions and environment may reflect social economic status. Research aimed at understanding links between social economic status and colorectal cancer progression is important for eliminating disparities in health outcomes.

RESUMO

Surgery plays a crucial role in the treatment of children with solid malignancies. A well-conducted operation is often essential for cure. Collaboration with the primary care team is important for determining if and when surgery should be performed, and if performed, an operation must be done in accordance with well-established standards. The long-term consequences of surgery also need to be considered. Indications and objectives for a procedure vary. Providing education and developing and analyzing new research protocols that include aims relevant to surgery are key objectives of the Surgery Discipline of the Children's Oncology Group. The critical evaluation of emerging technologies to ensure safe, effective procedures is another key objective. Through research, education, and advancing technologies, the role of the pediatric surgeon in the multidisciplinary care of children with solid malignancies will continue to evolve.

RESUMO

PURPOSE: Identifying the number of cases required for a fellow to achieve competence has been challenging. Workplace-based assessment (WBA) systems make collecting performance data practical and create the opportunity to translate WBA ratings into probabilistic statements about a fellow's likelihood of performing to a given standard on a subsequent assessment opportunity. METHODS: We compared data from two pediatric surgery training programs that used the performance rating scale from the Society for Improving Medical Professional Learning (SIMPL). We used a Bayesian generalized linear mixed effects model to examine the relationship past and future performance for three procedures: Laparoscopic Inguinal Hernia Repair, Laparoscopic Gastrostomy Tube Placement, and Pyloromyotomy. RESULTS: For site one, 26 faculty assessed 9 fellows on 16 procedures yielding 1094 ratings, of which 778 (71%) earned practice-ready ratings. For site two, 25 faculty rated 3 fellows on 4 unique procedures yielding 234 ratings of which 151 (65%) were deemed practice-ready. We identified similar model-based future performance expectations, with prior practice-ready ratings having a similar average effect across both sites (Site one, B = 0.25; Site two, B = 0.25). Similar prior practice-ready ratings were needed for Laparoscopic G-Tube Placement (Site one = 13; Site two = 14), while greater differences were observed for Laparoscopic Inguinal Hernia Repair (Site one = 10; Site two = 15) and Pyloromyotomy (Site one = 10; Site two = 15). CONCLUSION: Our approach to modeling operative performance data is effective at determining future practice readiness of pediatric surgery fellows across multiple faculty and fellow groups. This method could be used to establish minimum case number requirements. TYPE OF STUDY: Original manuscript, Study of Diagnostic Test. LEVEL OF EVIDENCE: II.

RESUMO

Neuroblastoma (NB) is the most common solid extracranial malignancy of childhood with an incidence of 1 per 100,000 in the United States compromising approximately 10 % of childhood cancer. Unfortunately, patients with high-risk NG continue to have long-term survival less than 50 %. Both Children's Oncology Group and the International Society of Paediatric Oncology have demonstrated the important role of surgery in the treatment of high-risk NB. Herein, we compose the results of an extensive literature review as well as expert opinion from leaders in pediatric surgical oncology, to present the critical elements of effective surgery for high-risk neuroblastoma.

RESUMO

PURPOSE: Despite limited genetic and histologic heterogeneity, Ewing sarcoma (EwS) tumor cells are transcriptionally heterogeneous and display varying degrees of mesenchymal lineage specification in vitro. In this study, we investigated if and how transcriptional heterogeneity of EwS cells contributes to heterogeneity of tumor phenotypes in vivo. EXPERIMENTAL DESIGN: Single-cell proteogenomic-sequencing of EwS cell lines was performed and integrated with patient tumor transcriptomic data. Cell subpopulations were isolated by FACS for assessment of gene expression and phenotype. Digital spatial profiling and human whole transcriptome analysis interrogated transcriptomic heterogeneity in EwS xenografts. Tumor cell subpopulations and matrix protein deposition were evaluated in xenografts and patient tumors using multiplex immunofluorescence staining. RESULTS: We identified CD73 as a biomarker of highly mesenchymal EwS cell subpopulations in tumor models and patient biopsies. CD73+ tumor cells displayed distinct transcriptional and phenotypic properties, including selective upregulation of genes that are repressed by EWS::FLI1, and increased migratory potential. CD73+ cells were distinguished in vitro and in vivo by increased expression of matrisomal genes and abundant deposition of extracellular matrix (ECM) proteins. In epithelial-derived malignancies, ECM is largely deposited by cancer-associated fibroblasts (CAF), and we thus labeled CD73+ EwS cells, CAF-like tumor cells. Marked heterogeneity of CD73+ EwS cell frequency and distribution was detected in tumors in situ, and CAF-like tumor cells and associated ECM were observed in peri-necrotic regions and invasive foci. CONCLUSIONS: EwS tumor cells can adopt CAF-like properties, and these distinct cell subpopulations contribute to tumor heterogeneity by remodeling the tumor microenvironment.

RESUMO

Adrenocortical carcinoma (ACC) is a rare but highly aggressive cancer with limited treatment options and poor survival for patients with advanced disease. An improved understanding of the transcriptional programs engaged in ACC will help direct rational, targeted therapies. Whereas activating mutations in Wnt/ß-catenin signaling are frequently observed, the ß-catenin-dependent transcriptional targets that promote tumor progression are poorly understood. To address this question, we analyzed ACC transcriptome data and identified a novel Wnt/ß-catenin-associated signature in ACC enriched for the extracellular matrix (ECM) and predictive of poor survival. This suggested an oncogenic role for Wnt/ß-catenin in regulating the ACC microenvironment. We further investigated the minor fibrillar collagen, collagen XI alpha 1 (COL11A1), and found that COL11A1 expression originates specifically from cancer cells and is strongly correlated with both Wnt/ß-catenin activation and poor patient survival. Inhibition of constitutively active Wnt/ß-catenin signaling in the human ACC cell line, NCI-H295R, significantly reduced the expression of COL11A1 and other ECM components and decreased cancer cell viability. To investigate the preclinical potential of Wnt/ß-catenin inhibition in the adrenal microenvironment, we developed a minimally invasive orthotopic xenograft model of ACC and demonstrated that treatment with the newly developed Wnt/ß-catenin:TBL1 inhibitor Tegavivint significantly reduced tumor growth. Together, our data support that the inhibition of aberrantly active Wnt/ß-catenin disrupts transcriptional reprogramming of the microenvironment and reduces ACC growth and survival. Furthermore, this ß-catenin-dependent oncogenic program can be therapeutically targeted with a newly developed Wnt/ß-catenin inhibitor. These results show promise for the further clinical development of Wnt/ß-catenin inhibitors in ACC and unveil a novel Wnt/ß-catenin-regulated transcriptome.

RESUMO

Attrition is high among surgical trainees, and six of ten trainees consider leaving their programs, with two ultimately leaving before completion of training. Given known historically and systemically rooted biases, Black surgical trainees are at high risk of attrition during residency training. With only 4.5% of all surgical trainees identifying as Black, underrepresentation among their peers can lend to misclassification of failure to assimilate as clinical incompetence. Furthermore, the disproportionate impact of ongoing socioeconomic crisis (e.g., COVID-19 pandemic, police brutality etc.) on Black trainees and their families confers additional challenges that may exacerbate attrition rates. Thus, attrition is a significant threat to medical workforce diversity and health equity. There is urgent need for surgical programs to develop proactive approaches to address attrition and the threat to the surgical workforce. In this Society of Black Academic Surgeons (SBAS) white paper, we provide a framework that promotes an open and inclusive environment conducive to the retention of Black surgical trainees, and continued progress towards attainment of health equity for racial and ethnic minorities in the United States.

RESUMO

PURPOSE: Despite trends toward equal gender representation among medical school graduates, surgical trainees and fellows, diversity in higher levels of pediatric surgery is largely unstudied. This study aims to quantify gender diversity among leadership of pediatric surgical associations and societies across the globe. METHODS: National and international pediatric surgical organizations were identified from the websites of the American Pediatric Surgical Association (APSA) and World Federation of Associations of Pediatric Surgery (WOFAPS). Compositional gender data of current and past organizational leadership was collected by examining publicly available archives of executive membership rosters. If roster pictures were not available, member names were input into social media sites and other search engines to ensure accurate gender denotation. Univariate analyses of organizational metrics and aggregate data of 5-year time intervals were performed via Fischer's Exact Test with significance of p < 0.05. RESULTS: Nineteen pediatric surgical organizations were included for study analysis. Of 189 current organizational leaders, 50 (26.4%) are women. Eight organizations (42.1%) have less than 20% of leadership positions filled by women members, while two executive boards have no women members. Four organizations (22.2%) have a current woman seated as president/chairperson. Historical gender distribution stratified by organization demonstrates a range of 0-7.8% (p = 0.99), with one organization having yet to elect a woman president/chairperson. Longitudinally, women presidential representation remained consistently low (5-11%) across all time intervals from 1993 to 2022 (p = 0.35). CONCLUSIONS: Despite advances in diversity in medical school graduates, surgical training, and workforce recruitment, there are still significant disparities in gender representation within pediatric surgery societal leadership. LEVEL OF EVIDENCE: IV.

RESUMO

INTRODUCTION: Diversity, Equity, and Inclusion (DEI) are concepts common in surgery. However, these can be difficult to define, and what constitutes DEI can be vague. Closing this knowledge gap, particularly within pediatric surgery, would be helpful to understand the views and needs of current surgeons. METHODS: 1558 APSA members were sent an anonymous survey, of which 423 (27%) responded. Respondents were asked about their demographics, views on what constitutes diversity as well as questions on how DEI is handled within APSA and definitions of common DEI terms. RESULTS: Of 11 possible diversity measures, members agreed that a median of 9 (IQR 7-11) counted towards diversity. The most common being race and ethnicity (98%), gender (96%), sexual orientation (93%), religion (92%), age (91%), and disability (90%). On a 5-point Likert scale, the median response was 4 or greater on questions regarding how APSA handles issues related to DEI. However, members who identify as black were less likely to score in favor of APSA, and members identifying as women were more likely to rank higher importance of DEI initiatives. We also captured subjective responses on DEI terminology. CONCLUSION: Respondents had broad definitions of diversity. There is support for further DEI initiatives and how APSA handles DEI, however this perception differs based on identities. There is significant variability in beliefs and views regarding DEI definitions and understanding this is helpful for the organization moving forward. LEVEL OF EVIDENCE: IV. TYPE OF STUDY: Original Research.

RESUMO

Tumor heterogeneity is a major driver of cancer progression. In epithelial-derived malignancies, carcinoma-associated fibroblasts (CAFs) contribute to tumor heterogeneity by depositing extracellular matrix (ECM) proteins that dynamically remodel the tumor microenvironment (TME). Ewing sarcomas (EwS) are histologically monomorphous, mesenchyme-derived tumors that are devoid of CAFs. Here we identify a previously uncharacterized subpopulation of transcriptionally distinct EwS tumor cells that deposit pro-tumorigenic ECM. Single cell analyses revealed that these CAF-like cells differ from bulk EwS cells by their upregulation of a matrisome-rich gene signature that is normally repressed by EWS::FLI1, the oncogenic fusion transcription factor that underlies EwS pathogenesis. Further, our studies showed that ECM-depositing tumor cells express the cell surface marker CD73, allowing for their isolation ex vivo and detection in situ. Spatial profiling of tumor xenografts and patient biopsies demonstrated that CD73 + EwS cells and tumor cell-derived ECM are prevalent along tumor borders and invasive fronts. Importantly, despite loss of EWS::FLI1-mediated gene repression, CD73 + EwS cells retain expression of EWS::FLI1 and the fusion-activated gene signature, as well as tumorigenic and proliferative capacities. Thus, EwS tumor cells can be reprogrammed to adopt CAF-like properties and these transcriptionally and phenotypically distinct cell subpopulations contribute to tumor heterogeneity by remodeling the TME.

RESUMO

INTRODUCTION: Bias and discrimination remain pervasive in the medical field and increase the risk of burnout, mental health disorders, and medical errors. The experiences of APSA members with bias and discrimination are unknown, therefore the APSA committee on Diversity, Equity and Inclusion conducted a survey to characterize the prevalence of bias and discrimination. METHODS: 1558 APSA members were sent an anonymous survey, of which 423 (27%) responded. Respondents were asked about their demographics, knowledge of implicit bias, and experience of bias and discrimination within their primary workplace, APSA, and APSA committees. Data were analyzed using Fisher's Exact test, Kruskal-Wallis test, and multivariable logistic regression as appropriate with significance defined as p<0.05. RESULTS: Discrimination was reported across all levels of practice, academic appointments, race, ethnicity, and gender identities. On multivariable analysis, surgical trainees (OR 3.6) as well as Asian American and Pacific Islander (OR 4.8), Black (OR 5.2), Hispanic (OR 8.2) and women (OR 8.7) surgeons were more likely to experience bias and discrimination in the workplace. Community practice surgeons were more likely to experience discrimination within APSA committees (OR 3.6). Members identifying as Asian (OR 0.4), or women (OR 0.6) were less likely to express comfort reporting instances of bias and discrimination. CONCLUSION: Workplace discrimination exists across all training levels, academic appointments, and racial and gender identities. Trainees and racial- and gender-minority surgeons report disproportionately high prevalence of bias and discrimination. Improving reporting mechanisms and implicit bias training are possible initiatives in addressing these findings.

RESUMO

INTRODUCTION: There are existing healthcare disparities in pediatric surgery today. Identity and racial incongruity between patients and providers contribute to systemic healthcare inequities and negatively impacts health outcomes of minoritized populations. Understanding the current demographics of the American Pediatric Surgical Association and therefore the cognitive diversity represented will help inform how best to strategically build the organization to optimize disparity solutions and improve patient care. METHODS: 1558 APSA members were sent an anonymous electronic survey. Comparative data was collected from the US Census Bureau and the Association of American Medical Colleges. Results were analyzed using standard statistical tests. RESULTS: Of 423 respondents (response rate 27%), the race and ethnicity composition were 68% non Hispanic White, 12% Asian American and Pacific Islander, 6% Hispanic, 5% multiracial, and 4% Black/African American. Respondents were 35% women, 63% men, and 1% transgender, androgyne, or uncertain. Distribution of sexual identity was 97% heterosexual and 3% LGBTQIA. Religious identity was 50% Christian, 22% Agnostic/Atheist, 11% Jewish, 3% Hindu, and 2% Muslim. 32% of respondents were first-generation Americans. Twenty-four different primary languages were spoken, and 46% of respondents were conversational in a second language. These findings differ in meaningful ways from the overall American population and from the population of matriculants in American medical schools. CONCLUSION: There are substantial differences in the racial, gender, and sexual identity composition of APSA members compared with the overall population in the United States. To achieve excellence in patient care and innovate solutions to existing disparities, representation, particularly in leadership is essential. TYPE OF STUDY: Survey; original research. LEVEL OF EVIDENCE: Level IV.

RESUMO

INTRODUCTION: Von Hippel-Lindau disease (VHL) is a rare cause of hereditary bilateral Pheochromocytomas (PHEO). Traditionally, treatment has been total adrenalectomy due to a lifetime risk of developing new tumors. Limited data exists on the surgical management of bilateral PHEO in children with VHL. We reviewed our experience with laparoscopic partial adrenalectomy for bilateral PHEO. METHODS: A retrospective review was performed of patients undergoing adrenalectomy for PHEO in children with VHL from 2004 to 2019. RESULTS: Eight children with VHL diagnosed with bilateral PHEO underwent 16 adrenalectomies (10 synchronous, 5 metachronous, 1 for recurrence). Median age at diagnosis was 13 [range 8-17] years with a median tumor size of 2.3 [range 0.5-7.7] cm. Of 16 adrenalectomies, all were performed laparoscopically, 14 were partial adrenalectomies; 2 patients required a contralateral total adrenalectomy due to size and diffuse multinodularity. There were no postoperative complications. No patients required corticosteroid replacement at the end of the study period. Two patients had new ipsilateral tumors identified after a median follow up of 5 [range 4-6] years with one undergoing repeat partial adrenalectomy. There were no mortalities in the study period. CONCLUSION: Partial adrenalectomy for bilateral PHEO in patients with VHL is safe and does not compromise outcomes. When technically feasible, laparoscopic partial adrenalectomy should be considered as a primary surgical approach for children with VHL. LEVEL OF EVIDENCE: Level IV - Case series with no comparison group.

RESUMO

OBJECTIVE: To determine the impact of tumor characteristics and treatment approach on (1) local recurrence, (2) scoliosis development, and (3) patient-reported quality of life in children with sarcoma of the chest wall. SUMMARY OF BACKGROUND DATA: Children with chest wall sarcoma require multimodal therapy including chemotherapy, surgery, and/or radiation. Despite aggressive therapy which places them at risk for functional impairment and scoliosis, these patients are also at significant risk for local recurrence. METHODS: A multi-institutional review of 175 children (median age 13 years) with chest wall sarcoma treated at seventeen Pediatric Surgical Oncology Research Collaborative institutions between 2008 and 2017 was performed. Patient-reported quality of life was assessed prospectively using PROMIS surveys. RESULTS: The most common diagnoses were Ewing sarcoma (67%) and osteosarcoma (9%). Surgical resection was performed in 85% and radiation in 55%. A median of 2 ribs were resected (interquartile range = 1-3), and number of ribs resected did not correlate with margin status ( P = 0.36). Local recurrence occurred in 23% and margin status was the only predictive factor(HR 2.24, P = 0.039). With a median follow-up of 5 years, 13% developed scoliosis (median Cobb angle 26) and 5% required corrective spine surgery. Scoliosis was associated with posteriorrib resection (HR 8.43; P= 0.003) and increased number of ribs resected (HR 1.78; P = 0.02). Overall, patient-reported quality of life is not impaired after chest wall tumor resection. CONCLUSIONS: Local recurrence occurs in one-quarter of children with chest wall sarcoma and is independent of tumor type. Scoliosis occurs in 13% of patients, but patient-reported quality of life is excellent.

RESUMO

Sex inequity in academic achievement was well documented before the COVID-19 pandemic, and evolving data suggest that women in academic surgery are disproportionately disadvantaged by the pandemic. This perspective piece reviews currently accepted solutions to the sex achievement gap, with their associated shortcomings. We also propose innovative strategies to overcoming barriers to sex equity in academic medicine that broadly fall into three categories: strategies to mitigate inequitable caregiving responsibilities, strategies to reduce cognitive load, and strategies to value uncompensated, impactful work. These approaches address inequities at the system-level, as opposed to the individual-level, lifting the burden of changing the system from women.
