Chalfant V, Riveros C, Stec AA. Effect of social disparities on 10 year survival in pediatric patients with Wilms' tumor. Cancer Med 2022; 12:3452-3459. [PMID: 35946133 PMCID: PMC9939224 DOI: 10.1002/cam4.5124] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Revised: 06/12/2022] [Accepted: 07/24/2022] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND To stratify 10-year survival outcomes by degree of social disparities in pediatric Wilms' tumor patients. We applied the Social Deprivation Index (SDI) to survival outcomes from the national SEER database to elucidate the effects of lower socioeconomics on cancer survival. METHODS A retrospective cohort study was performed using the national Surveillance, Epidemiology, and End Results (SEER) oncology registry from 1975 to 2016 based on county-level data. Pediatric patients (<18 years old) with a diagnosis of WT (C64.9) and confirmed based on histology codes (8960/8963) were included. SDI scores were calculated for each patient and initially divided into quintiles. Patients were delineated into high-risk (>60th percentile/more deprived) or low-risk (<60th percentile/less deprived) groups. Statistics were assessed using Fisher's exact test, Student's t-test, and Kaplan-Meier assessed survival differences with log-rank test for trend. RESULTS A total of 3406 patients were included with 1366 patients reported in the high-risk group and 2040 patients in the low-risk group. Quintile data demonstrated a stratification in survival based on socioeconomic status. Patients in more socially deprived counties were significantly (p = 0.035) more likely to have worse overall survival compared with those living in less deprived areas at 10-year (87.3% vs 89.3%) follow-up. CONCLUSIONS 10-year overall and cancer-specific survival data for patients with Wilms' tumor stratify by socioeconomic lines. This represents an area that needs to be addressed in this pediatric oncologic population. Patients from more socially deprived areas have significantly worse 10-year overall survival rates and noticeably different 10-year cancer-specific survival rates.

Abstract
Emerging evidence suggests that KIF11 could play a pivotal role in cancer cell proliferation; however, its biological functions and molecular mechanisms in Wilms tumor (WT) cells are largely unknown. The aim of this study was to evaluate the clinical significance and therapeutic potential of KIF11 proteins in WT. KIF11 expression in WT tissues and adjacent nontumor tissues was determined using qRT-PCR, Western blotting, immunohistochemistry (IHC) and bioinformatics. The function of KIF11 protein was determined by its correlation with tumor cell growth, angiogenesis, and apoptosis using IHC and lentiviral vector-mediated KIF11 depletion. KIF11 expression was upregulated in WT tissues and was associated with WT clinical outcomes. Tumor KIF11 expression was significantly associated with the Ki67 proliferation index. CCK-8, flow-cytometric analysis, and Western blotting revealed that KIF11 knockdown significantly inhibited WT cell growth. Functional studies have indicated that increased KIF11 expression is significantly correlated with vascular endothelial growth factor (VEGF) expression and intratumoral microvessel density. We further confirmed that downregulated expression of KIF11 promoted cell apoptosis and significantly increased Bcl-2 and Bax expression. Our findings demonstrate that KIF11 plays a role in promoting the development of human WT and can serve as a potential molecular marker for the treatment of WT.

Differing interpretations of health care encounters: A qualitative study of non-Latinx health care providers' perceptions of Latinx patient behaviors. PLoS One 2020; 15:e0236706. [PMID: 32760146 PMCID: PMC7410271 DOI: 10.1371/journal.pone.0236706] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Accepted: 07/13/2020] [Indexed: 12/26/2022] Open
Abstract
INTRODUCTION Due to provider shortages, it is probable that non-Latinx health care providers (HCPs) will treat Latinx patients. Because of this discrepancy, both providers and patients are likely to experience barriers and cultural differences during medical encounters. This article discusses select cultural factors and behaviors such as language, communication styles, and health care practices of Latinx families through the lens of their non-Latinx HCPs. The purpose of this study was to examine how non-Latinx HCPs perceive and describe certain behaviors they observe during healthcare visits with Latinx patients and families, and to illustrate how those behaviors can alternatively be interpreted as representing Latinx cultural norms. METHODS This qualitative study used a template coding approach to examine narrative interviews conducted with 18 non-Latinx HCPs to report how they described interactions with and the behaviors of their Latinx patients. Template codes were based on well-established Latinx cultural norms (e.g., familismo, respeto, personalismo, simpatía, confianza). RESULTS Many HCP descriptions of Latinx patient behaviors were coded into the Latinx cultural values categories (familismo, personalismo, simpatía, respeto, and confianza) by the research team. Results suggest that HCPs were not aware of how several of their patients' behaviors may be culturally grounded, and that cultural differences between HCPs and their Latinx patients may exist. DISCUSSION Understanding how Latinx-specific cultural norms may be exhibited by Latinx patients and their families during healthcare encounters has potential to improve providers' understanding of patient behavior, helping to promote culturally congruent care for Latinxs.

Abstract
Objectives: miR-200c-3p has been shown to serve as a tumor suppressor in various tumor types. However, the biological function of miR-200c-3p in nephroblastoma remains unknown. This study aims to investigate the biological function and regulatory mechanisms of miR-200c-3p in nephroblastoma development. Methods: The expression of miR-200c-3p in nephroblastoma tissues and cells was evaluated by quantitative real-time polymerase chain reaction (qRT-PCR). The effects of miR-200c-3p on the proliferation and cell cycle of SK-NEP-1 nephroblastoma cell line were evaluated by CCK-8 assay, colony formation assay, and flow cytometry. The effects of miR-200c-3p on the migratory and invasive capacities of SK-NEP-1 cells were measured by wound healing assay and transwell assay. The ability of miR-200c-3p to target fibroblast growth factor receptor substrate 2 (FRS2) was detected by quantitative PCR, western blot, and luciferase reporter assay. Results: The expression of miR-200c-3p was significantly downregulated in nephroblastoma tissues and cells compared with that in normal renal tissues and cells. miR-200c-3p inhibited the proliferative, migratory, and invasive capacities of nephroblastoma cells by targeting FRS2. Conclusions: miR-200c-3p suppresses the malignant behaviors of nephroblastoma cells by downregulating the expression of FRS2.

Abstract
Wilms tumor (WT) is the most common type of renal malignancy in children. Survival rates are low and high-risk WT generally still carries a poor prognosis. To better elucidate the pathogenesis and tumorigenic pathways of high-risk WT, the present study presents an integrated analysis of RNA expression profiles of high-risk WT to identify predictive molecular biomarkers, for the improvement of therapeutic decision-making. mRNA sequence data from high-risk WT and adjacent normal samples were downloaded from The Cancer Genome Atlas to screen for differentially expressed genes (DEGs) using R software. From 132 Wilms tumor samples and six normal samples, 2,089 downregulated and 941 upregulated DEGs were identified. In order to identify hub DEGs that regulate target genes, weighted gene co-expression network analysis (WGCNA) was used to identify 11 free-scale gene co-expressed clusters. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were annotated using KEGG Orthology Based Annotation System annotation of different module genes. The Search Tool for the Retrieval of Interacting Genes was used to construct a protein-protein interaction network for the identified DEGs, and the hub genes of WGCNA modules were identified using the Cytohubb plugin with Cytoscape software. Survival analysis was subsequently performed to highlight hub genes with a clinical signature. The present results suggest that epidermal growth factor, cyclin dependent kinase 1, endothelin receptor type A, nerve growth factor receptor, opa-interacting protein 5, NDC80 kinetochore complex component and cell division cycle associated 8 are essential to high-risk WT pathogenesis, and they are closely associated with clinical prognosis.

Abstract
BACKGROUND Hispanic children with cancer experience poorer survival than their White counterparts. Infection is a known cause of cancer-related mortality; however, little is known about the risk of infection-related death among Hispanic children with cancer. We examine the association of Hispanic ethnicity with infection-related mortality and life-threatening events among children with cancer. PROCEDURE For a cohort of all pediatric cancer patients diagnosed from 1986 to 2012 and treated at a single tertiary care center, we obtained national death records to determine all-cause mortality and infection-related mortality, as well as intensive care unit (ICU) admissions as a surrogate for life-threatening events. Cox proportional hazard models assessed all-cause mortality and infection-related mortality using ethnicity as the main independent variable. ICU admission rates were modeled using a zero-inflated Poisson regression model. Models were adjusted for gender, diagnosis year, age, residential location, and diagnosis. RESULTS Of 6,198 patients, 741 (12%) were Hispanic. Mean follow-up was 11 years (SD = 8.04). There were 1,205 deaths, with 193 attributable to infection. Differences in all-cause mortality between Hispanic and non-Hispanic patients did not reach significance (hazard ratio [HR] = 1.14, 95% confidence interval [CI]: 0.96-1.36). However, Hispanic patients were 68% (HR = 1.68, 95% CI: 1.16-2.43) more likely to have an infection-related cause of death. Hispanic ethnicity was statistically associated with a higher rate of ICU admissions (rate ratio = 1.32, 95% CI: 1.12-1.56). CONCLUSION Hispanic pediatric cancer patients were more likely to have an infection-related death and higher rates of ICU admissions than non-Hispanic patients. Infection may be an overlooked contributor to poorer outcomes among Hispanic patients.

Abstract
Wilms' tumor (WT) is a most common renal cancer that occurs among children, and microRNA-19b (miR-19b) usually participates in various human cancers. Importantly, the PTEN/PI3K/Akt signaling pathway plays a key role in cell apoptosis, growth and proliferation. Thus, our present study aims to investigate the effect of miR-19b on the PTEN/PI3K/Akt signaling pathway during WT cell proliferation, migration, and apoptosis. WT tissues and adjacent normal tissues from WT patients were collected. qRT-PCR was applied to detect miR-19b expression in both the WT tissues and the adjacent normal tissues, immunohistochemistry was applied to detect the protein expressions of PTEN, P13K, and p-Akt, SK-NEP-1 cells were divided into the blank, negative control (NC), miR-19b mimics and miR-19b inhibitors groups. MTT assay, propidium iodide (PI) staining, Annexin-V/PI double-staining, Transwell assay and Western blotting were performed to examine cell proliferation, cycle, apoptosis, migration, and invasion, and the protein expressions of PTEN, P13K, Akt, and p-Akt. Increased miR-19b expression, positive expression rates of P13K and Akt, decreased PTEN expression rate, a negative correlation between PTEN expression and tumor lymph node metastasis, and a positive correlation between the expression of P13K and Akt and the clinical stages were observed in the WT tissues. The miR-19b inhibitors group exhibited decreased cell proliferation, cell cycle progression, migration and invasion, and protein expressions of PI3K and p-Akt but increased PTEN protein expression compared with the blank and NC groups. Thus, inhibition of miR-19b suppresses the progression of WT by modulating the PTEN/PI3K/AKT signaling pathway. J. Cell. Biochem. 118: 3424-3434, 2017. © 2017 Wiley Periodicals, Inc.

Abstract
BACKGROUND An increasing proportion of pediatric cancer patients in the United States are Latino and many have Spanish-speaking immigrant parents with limited English proficiency (LEP). Little is known about how language or undocumented immigration status impacts their care experience. PROCEDURE A cross-sectional survey was administered to English (N = 310) and Spanish-speaking LEP (N = 56) caregivers of pediatric cancer patients. To assess differences in healthcare experiences between the language groups, t-tests and chi-square statistics were used. Multivariable logistic regression evaluated associations between primary language and knowledge of clinical trial status. RESULTS Spanish-speaking caregivers were more likely to report higher rates of quitting or changing jobs as a direct result of their child's cancer, and their children were more likely to experience a delay in education. Although Spanish-speaking caregivers reported higher satisfaction with care, 32% reported feeling that their child would have received better care if English was their primary language. Spanish-speaking caregivers were more likely to incorrectly identify whether their child was on a clinical trial compared with English-speaking caregivers. The majority of Spanish-speaking caregivers reported at least one undocumented caregiver in the household and 11% of them avoided or delayed medical care for their child due to concerns over their undocumented immigration status. CONCLUSIONS Language barriers and undocumented immigration status may negatively impact the quality of informed decision-making and the care experience for Spanish-speaking LEP caregivers of pediatric cancer patients. These families may benefit from culturally appropriate Spanish language resources to improve communication and open a dialogue regarding undocumented immigration status.

Abstract
Wilms' tumor is the most common renal tumor in children in which diffusely anaplastic or unfavorable histology foreshadows poor prognosis. MicroRNAs are small, non-coding RNAs that negatively regulate gene expression at the posttranscriptional level. Accumulating evidence shows that microRNA dysregulation takes part in the pathogenesis of many renal diseases, such as chronic kidney diseases, polycystic kidney disease, renal fibrosis, and renal cancers. In Wilms' tumor, dysregulation of some key oncogenic or tumor-suppressing microRNAs, such as miR-17~92 cluster, miR-185, miR-204, and miR-483, has been documented. In this review, we will summarize current evidence on the role of dysregulated microRNAs in the development of Wilms' tumor.
