Abstract
BACKGROUND Socioeconomic factors have a significant impact on healthcare outcomes. Metrics such as area deprivation index (ADI) are used to quantify the anticipated influence of these factors. Here, we sought to assess the impact of socioeconomic factors on clinical outcomes among pediatric patients with solid tumor in our region. STUDY DESIGN We identified 3,863 pediatric patients who were diagnosed with a malignant solid tumor in the Texas Cancer Registry between 1995 and 2019. ADI was used to quantify socioeconomic determinants of health. These outcome variables were determined: stage of disease at diagnosis, time between diagnosis and treatment initiation, and overall mortality. Statistical analysis was performed using logistic regression, linear regression, Cox proportional hazards regression, and Kaplan-Meier survival curves. RESULTS A total of 53.5% of patients were male and the average age at diagnosis was 4.5 years. Forty-seven percent of patients were White, 13.3% were Black, 36.2% were Hispanic, 1.7% were Asian, and other rare minority groups made up 1.8%. On multivariable analysis, increased risk of death was associated with Black race, rare minority race, residence in a border county, and increasing ADI score, with the risk of death at 5 years rising 4% with each increasing ADI point. CONCLUSIONS Social determinants of health are associated with disparate outcomes among pediatric patients with solid tumor. Our results suggest that patients who are part of racial minority groups and those who reside in socioeconomically disadvantaged neighborhoods or regions near the Texas-Mexico border are at an increased risk of death. This information may be useful in strategizing outreach and expanding resources to improve outcomes in at-risk communities.

Bayesian inference for survival prediction of childhood Leukemia. Comput Biol Med 2023; 156:106713. [PMID: 36863191 DOI: 10.1016/j.compbiomed.2023.106713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 02/09/2023] [Accepted: 02/26/2023] [Indexed: 03/03/2023]
Abstract
BACKGROUND Childhood Leukemia is the most common type of cancer among children. Nearly 39% of cancer-induced childhood deaths are attributable to Leukemia. Nevertheless, early intervention has long been underdeveloped. Moreover, there are still a group of children succumbing to their cancer due to the cancer care resource disparity. Therefore, it calls for an accurate predictive approach to improve childhood Leukemia survival and mitigate these disparities. Existing survival predictions rely on a single best model, which fails to consider model uncertainties in predictions. Prediction from a single model is brittle, with model uncertainty neglected, and inaccurate prediction could lead to serious ethical and economic consequences. METHODS To address these challenges, we develop a Bayesian survival model to predict patient-specific survivals by taking model uncertainty into account. Specifically, we first develop a survival model predict time-varying survival probabilities. Second, we place different prior distributions over various model parameters and estimate their posterior distribution with full Bayesian inference. Third, we predict the patient-specific survival probabilities changing with respect to time by considering model uncertainty induced by posterior distribution. RESULTS Concordance index of the proposed model is 0.93. Moreover, the standardized survival probability of the censored group is higher than that of the deceased group. CONCLUSIONS Experimental results indicate that the proposed model is robust and accurate in predicting patient-specific survivals. It can also help clinicians track the contribution of multiple clinical attributes, thereby enabling well-informed intervention and timely medical care for childhood Leukemia.

Abstract
BACKGROUND Equitable access to pediatric organ transplantation is critical, although risk factors negatively impacting pre- and post-transplant outcomes remain. No synthesis of the literature on SDoH within the pediatric organ transplant population has been conducted; thus, the current systematic review summarizes findings to date assessing SDoH in the evaluation, listing, and post-transplant periods. METHODS Literature searches were conducted in Web of Science, Embase, PubMed, and Cumulative Index to Nursing and Allied Health Literature databases. RESULTS Ninety-three studies were included based on pre-established criteria and were reviewed for main findings and study quality. Findings consistently demonstrated disparities in key transplant outcomes based on racial or ethnic identity, including timing and likelihood of transplant, and rates of rejection, graft failure, and mortality. Although less frequently assessed, variations in outcomes based on geography were also noted, while findings related to insurance or SES were inconsistent. CONCLUSION This review underscores the persistence of SDoH and disparity in equitable transplant outcomes and discusses the importance of individual and systems-level change to reduce such disparities.

Measuring disparities in event-free survival among children with acute lymphoblastic leukemia in an academic institute in Oklahoma, 2005-2019. Cancer Epidemiol 2022; 81:102275. [PMID: 36215916 PMCID: PMC10079780 DOI: 10.1016/j.canep.2022.102275] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 09/09/2022] [Accepted: 10/02/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Acute lymphoblastic leukemia (ALL) is the most common type of childhood cancer. While there have been successes in the treatment of leukemia, less information is available on reasons for disparities in event-free survival (EFS) among underserved populations. METHODS We partnered with a children's hospital at an academic institution to abstract data from the institution's cancer registry, the state cancer registry, and electronic medical records on cancer diagnosis, treatment, and outcomes for children with ALL (n = 275) diagnosed from 2005 to 2019 prior to age 20. We evaluated the relation between 1) race/ethnicity, 2) distance to the children's hospital, and 3) area deprivation with EFS, defined as time from diagnosis to relapse, death, or the end of the study period. We evaluated differences in EFS using Kaplan-Meier analysis with the log-rank test. We used the Cox Proportional Hazards Model for multivariable survival analyses. RESULTS Most children were diagnosed with ALL under five years of age (45%) and with Pre-B ALL (87%). Twelve percent of children experienced a relapse and 5% died during induction or remission. EFS at 5 years was 82%. Non-Hispanic (NH) Black children had worse, though imprecise, EFS compared to NH White children (Adjusted Hazard Ratio: 2.07, 95% CI: 0.80, 5.38). Children residing in areas with higher deprivation had a higher adjusted hazard of poor outcomes compared to the least deprived areas, though estimates were imprecise (2nd quartile HR: 1.51, 3rd quartile: 1.85, 4th quartile: 1.62). We observed no association between distance to the children's hospital and EFS. CONCLUSION We observed poorer EFS for NH Black children and children residing in areas with high deprivation, though the estimates were not statistically significant. Our next steps include further evaluating socioeconomic factors in both rural and urban children to identify disparities in outcomes for children with ALL and other childhood cancers.

Abstract
The study of immune genes and immune cells is highly focused in recent years. To find immunological genes with prognostic value, the current study examines childhood acute myeloid leukemia according to gender. The TARGET database was used to gather the "mRNA expression profile data" and relevant clinical data of children with AML. To normalize processing and find differentially expressed genes (DEG) between male and female subgroups, the limma software package is utilized. We identified prognostic-related genes and built models using LASSO, multivariate Cox, and univariate Cox analysis. The prognostic significance of prognostic genes was then examined through the processing of survival analysis and risk score (RS) calculation. We investigated the connections between immune cells and prognostic genes as well as the connections between prognostic genes and medications. Finally, five immune genes from the TARGET database have been identified. These immune genes are considerably correlated to the prognosis of male patients.

Abstract
Background: When compared with White patients, racial and ethnic minorities experience greater barriers to quality end-of-life care. Each year, approximately 52,000 children die in the United States, yet little is known about the disparities in pediatric palliative care, especially when looking at psychosocial palliative care services such as those provided by child life specialists, social workers, and pediatric psychologists. Objectives: In an effort to consolidate and synthesize the literature on this topic for psychosocial professionals working with children and families confronting a life-threatening diagnosis, a review was conducted. Design: This work was a systematic review of several academic databases that were searched from January 2000 to December 2020 for studies exploring disparities in pediatric end-of-life services and written in English. Setting/Subjects: This review was conducted in the United States. The search yielded 109 articles, of which 16 were included for review. Measurements: Three psychosocial researchers independently reviewed, critically appraised, and synthesized the results. Results: Emerging themes from the literature (n = 16) include service enrollment, decision making, and communication. Results highlight a lack of research discussing psychosocial variables and the provision of psychosocial services. Despite this gap, authors were able to extract recommendations relevant to psychosocial providers from the medical-heavy literature. Conclusions: Recommendations call for more research specific to possible disparities in psychosocial care as this is vital to support families of all backgrounds who are confronting the difficulties of pediatric loss.

Abstract
BACKGROUND Medulloblastoma (MB),the most common malignant brain tumor of childhood has survival outcomes exceeding 80% for standard-risk and 60% for high-risk patients in high-income countries (HICs). These results have not been replicated in low- and middle-income countries (LMICs), where 80% of children with cancer live. METHODS This is a retrospective review of 114 children aged 3-18 years diagnosed with MB from 1997 to 2016 at National Cancer Institute (INCA). Sociodemographic, clinical, and treatment data were extracted from the medical records and summarized descriptively. Overall survival (OS) and progression-free survival (PFS) were calculated using the Kaplan-Meier method. RESULTS The male-to-female ratio was 1.32 and the median age at diagnosis was 8.2 years. Headache (83%) and nausea/vomiting (78%) were the most common presenting symptoms. Five-year OS was 59.1% and PFS was 58.4%. The OS for standard-risk and high-risk patients was 69% and 53%, respectively. The median time to diagnosis interval was 50.5 days and the median time from surgery to radiation therapy initiation was 50.4 days. Patients who lived >40 km from INCA fared better (OS = 68.2% vs. 51.1%, p = .032). Almost 20% of families lived below the Brazilian minimum wage. Forty-five patients (35%) had metastatic disease at admission. Gross total resection was achieved in 57% of the patitents. CONCLUSIONS Although there are considerable barriers to deliver effective MB treatment in countries like Brazil, the OS seen in the present study demonstrates that good outcomes are not only feasible but can and should be increased with appropriate interventions.

Abstract
OBJECTIVE Low socioeconomic status is a determinant of pediatric traumatic brain injury (TBI) incidence and severity. In this study, the authors used National (Nationwide) Inpatient Sample (NIS) data to evaluate socioeconomic and health disparities among children hospitalized after TBI. METHODS This retrospective study identified pediatric patients aged 0 to 19 years with ICD-9 codes for TBI in the NIS database from 2012 to 2015. Socioeconomic variables included race, sex, age, census region, and median income of the patient residential zip code. Outcomes included mechanism of injury, hospital length of stay (LOS), cost, disposition at discharge, death, and inpatient complications. Multivariate linear regressions in log scale were built for LOS and cost. Logistic regressions were built for death, disposition, and inpatient complications. RESULTS African American, Hispanic, and Native American patients experienced longer LOSs (β 0.06, p < 0.001; β 0.03, p = 0.03; β 0.13, p = 0.02, respectively) and increased inpatient costs (β 0.13, p < 0.001; β 0.09, p < 0.001; β 0.14, p = 0.03, respectively). Females showed increased rates of medical complications (OR 1.57, p < 0.001), LOS (β 0.025, p = 0.02), and inpatient costs (p = 0.04). Children aged 15 to 19 years were less likely to be discharged home (OR 3.99, p < 0.001), had increased mortality (OR 1.32, p = 0.03) and medical complications (OR 1.84, p < 0.001), and generated increased costs (p < 0.001). CONCLUSIONS The study results have demonstrated that racial minorities, females, older children, and children in lower socioeconomic groups were at increased risk of poor outcomes following TBI, including increased LOS, medical complications, mortality, inpatient costs, and worse hospital disposition. Public education and targeted funding for these groups will ensure that all children have equal opportunity for optimal clinical outcomes following TBI.

Abstract
Cytogenetic lesions in pediatric AML differ by race-ethnicity including higher rates of specific poor prognosis lesions among Black children. Racial-ethnic minorities experience worse outcomes in pediatric AML regardless of genetic disease features.
Black and Hispanic children with acute myeloid leukemia (AML) have worse outcomes compared with White children. AML is a heterogeneous disease with numerous genetic subtypes in which these disparities have not been specifically investigated. In this study, we used the Therapeutically Applicable Research to Generate Effective Treatments (TARGET) database to examine the association of race-ethnicity with leukemia cytogenetics, clinical features, and survival outcomes within major cytogenetic subgroups of pediatric AML. Compared with White non-Hispanic patients, t(8;21) AML was more prevalent among Black (odds ratio [OR], 2.22; 95% confidence interval [CI], 1.28-3.74) and Hispanic patients (OR, 1.74; 95% CI, 1.05-2.83). The poor prognosis KMT2A rearrangement t(6;11)(q27;q23) was more prevalent among Black patients (OR, 6.12; 95% CI, 1.81-21.59). Among those with KMT2Ar AML, Black race was associated with inferior event-free survival (EFS) (hazard ratio [HR], 2.31; 95% CI, 1.41-3.79) and overall survival (OS) (HR, 2.54; 1.43-4.51). Hispanic patients with KMT2Ar AML also had inferior EFS (HR, 2.20; 95% CI, 1.27-3.80) and OS (HR, 2.07; 95% CI, 1.09-3.93). Similarly, among patients with t(8;21) or inv(16) AML (ie, core-binding factor [CBF] AML), Black patients had inferior outcomes (EFS HR, 1.93; 95% CI, 1.14-3.28 and OS HR, 3.24; 95% CI, 1.60-6.57). This disparity was not detected among patients receiving gemtuzumab ozogamicin (GO). In conclusion, racial-ethnic disparities in survival outcomes among young people with AML are prominent and vary across cytogenetic subclasses. Future studies should explore the socioeconomic and biologic determinants of these disparities.

Abstract
BACKGROUND Marked reductions in childhood cancer mortality occurred over the last decades in high-income countries and, to a lesser degree, in middle-income countries. This study aimed to monitor mortality trends in the Americas and Australasia, focusing on areas showing unsatisfactory trends. METHODS Age-standardized mortality rates per 100,000 children (aged 0-14 years) from 1990 to 2017 (or the last available calendar year) were computed for all neoplasms and 8 leading childhood cancers in countries from the Americas and Australasia, using data from the World Health Organization database. A joinpoint regression was used to identify changes in slope of mortality trends for all neoplasms, leukemia, and neoplasms of the central nervous system (CNS) for major countries. RESULTS Over the last decades, childhood cancer mortality continued to decrease by approximately 2% to 3% per year in Australasian countries (ie, Japan, Korea, and Australia), by approximately 1.5% to 2% in North America and Chile, and 1% in Argentina. Other Latin American countries did not show any substantial decrease. Leukemia mortality declined in most countries, whereas less favorable trends were registered for CNS neoplasms, particularly in Latin America. Around 2016, death rates from all neoplasms were 4 to 6 per 100,000 boys and 3 to 4 per 100,000 girls in Latin America, and 2 to 3 per 100,000 boys and approximately 2 per 100,000 girls in North America and Australasia. CONCLUSIONS Childhood cancer mortality trends declined steadily in North America and Australasia, whereas they were less favorable in most Latin American countries. Priority must be given to closing the gap by providing high-quality care for all children with cancer worldwide. LAY SUMMARY Advances in childhood cancer management have substantially improved the burden of these neoplasms over the past 40 years, particularly in high-income countries. This study aimed to monitor recent trends in America and Australasia using mortality data from the World Health Organization. Trends in childhood cancer mortality continued to decline in high-income countries by approximately 2% to 3% per year in Japan, Korea, and Australia, and 1% to 2% in North America. Only a few Latin American countries showed favorable trends, including Argentina, Chile, and Mexico, whereas other countries with limited resources still lagged behind.

Abstract
Adult cancer disparities have been documented for decades and continue to persist despite clinical advancements in cancer prevention, detection, and treatment. Pediatric cancer survival has improved significantly in the United States for the past 5 decades to over 80%; however, disparate outcomes among children and adolescents with cancer still affect many populations in the United States and globally, including racial and ethnic minorities, populations with low socioeconomic status, and residents of underserved areas. To achieve equitable outcomes for all children and adolescents with cancer, it is imperative that concerted multilevel approaches be carried out to understand and address health disparities and to ensure access to high-quality cancer care. Addressing social determinants of health, such as removing barriers to health care access and ensuring access to social supports, can reduce pediatric cancer disparities. Nevertheless, public health policy, health system interventions, and innovative delivery of evidence-based services are critically needed. Partnerships among patients, caregivers, and health care providers, and among health care, academic, and governmental institutions, have a pivotal role in reducing cancer disparities and improving outcomes in the 21st century.

Abstract
PURPOSE OF REVIEW The high cure rates of children with cancer in high-income countries (HICs) are due to the impact of biomedical innovations on children with highly fatal diseases. We discuss why these innovations have not benefitted most children with cancer globally and propose broad strategies to reduce these disparities. RECENT FINDINGS Over 85% of children with cancer in HIC are cured while less than 20% in many low-income countries survive the disease. Hence, childhood cancer survival is poor globally since over 80% of children with cancer live in low-income and middle-income countries (LMICs). Inadequate skilled workforce and health infrastructure across all disciplines of pediatrics in LMIC are the main reasons for these disparities. Although biological differences may contribute to these disparities as well, many are unconfirmed because they are confounded by differences in referral patterns and clinical capacity. HIC partnerships with LMIC that focus on locally based pediatrics training and clinical infrastructure building are beginning to close the gap. SUMMARY Pediatric oncology is symbolic of the significant disparities in childhood survival arising from poverty, inadequate pediatric infrastructure, and skilled workforce in LMIC. Partnerships with HIC that build multidisciplinary pediatrics capacity and clinical infrastructure are beginning to make transformative improvements.

Abstract
COTI-2 is a third-generation thiosemicarbazone, which is effective against a diverse group of human cancer cell lines at nanomolar concentrations. COTI-2 also showed superior activity against tumor cells, in vitro and in vivo. As a high efficacy and low toxicity agent, it currently candidates in a phase I clinical study of gynecological malignancies and head and neck squamous cell carcinoma (HNSCC). However, its effect in pediatric T-cell acute lymphoblastic leukemia (T-ALL) is not clear. This study investigates the effect of COTI-2 on T-ALL Jurkat cells in vitro and in vivo. Jurkat cells were exposure to COTI-2 at different concentration and time. Cell apoptosis was detected by flow cytometry to examine the sensitivity of Jurkat cell lines treated with either COTI-2 alone or in combination with MiR-203 mimic or inhibitor in vitro. An orthotopic mouse model was used to examine the sensitivity of Jurkat cells treated with COTI-2 in vivo. Western blotting and RT-qPCR were performed to dissect molecular mechanisms. The results showed that COTI-2 promotes apoptosis of Jurkat cells in dose-and time-dependent way. Enforced expression of miR-203 promotes COTI-2-mediated cell apoptosis, whereas miR-203 silencing attenuates COTI-2-mediated cell apoptosis in Jurkat cells in vitro. COTI-2 is also effective against growth of Jurkat cells in vivo. Mechanistically, COTI-2 induced miR-203 upregulation and inhibited caspase-3/9 activaty leading to inhibition of cell apoptosis. Taken together, COTI-2 inhibits tumor growth in vitro and in vivo in Jurkat cells likely through miR-203-dependent mechanisms. COTI-2 may be a potential approach for T-ALL treatment.
