RESUMEN

BACKGROUND: Sexual function (SF) concerns are common among adolescent and young adult (AYA) cancer survivors, are underrecognized and undertreated. This study sought AYA oncology provider input on the implementation of an SF screening tool to address this unmet need. PROCEDURE: Semi-structured interviews were completed with oncology providers (n = 25) who care for AYAs at a single institution. Interviews sought to understand barriers to addressing SF, elicit perspectives on use of an established screening tool, and obtain recommendations for SF screening intervention development and implementation. Interviews were developed using the Consolidated Framework for Implementation Research (CFIR); thematic analysis-guided interpretation. RESULTS: AYA oncology providers were in favor of using an SF screening tool, but confirmed previously identified barriers and implementation considerations within multiple CFIR domains, including concerns about privacy, patient comfort, provider buy-in, provider knowledge, resource needs, and workflow/capacity constraints. They identified numerous strategies to address barriers through screening intervention design and implementation approaches. For example, provider buy-in could be optimized through education, availability of clinical resources, creation of a dedicated sexual healthcare team, provider engagement in intervention development, and leadership involvement. CONCLUSIONS: Development and implementation of an effective SF screening intervention is necessary to improve diagnosis and treatment of sexual dysfunction, with the ultimate goal of improving sexual health-related quality of life in AYA cancer survivors. AYA oncology providers identified numerous intervention and implementation design strategies for the development and implementation of an SF screening intervention, which must be integrated with patient recommendations.

RESUMEN

Ewing sarcoma is the second most common bone cancer in children, accounting for 2% of pediatric cancer diagnoses. Patients who present with metastatic disease at the time of diagnosis have a dismal prognosis, compared to the >70% 5-year survival of those with localized disease. Here, we utilized single cell RNA-sequencing to characterize the transcriptional landscape of primary Ewing sarcoma tumors and surrounding tumor microenvironment (TME). Copy-number analysis identified subclonal evolution within patients even prior to treatment. Primary tumor samples demonstrate a heterogenous transcriptional landscape with several conserved gene expression programs, including those composed of genes related to proliferation and EWS targets. We also were able to identify the composition of the TME and molecularly dissect the transcriptional profile of circulating tumor cells in peripheral blood at the time of diagnosis.

RESUMEN

PURPOSE: The optimal management of fever without severe neutropenia (absolute neutrophil count [ANC] ≥500/µL) in pediatric patients with cancer is undefined. The previously proposed Esbenshade Vanderbilt (EsVan) models accurately predict bacterial bloodstream infections (BSIs) in this population and provide risk stratification to aid management, but have lacked prospective external validation. MATERIALS AND METHODS: Episodes of fever with a central venous catheter and ANC ≥500/µL occurring in pediatric patients with cancer were prospectively collected from 18 academic medical centers. Variables included in the EsVan models and 7-day clinical outcomes were collected. Five versions of the EsVan models were applied to the data with calculation of C-statistics for both overall BSI rate and high-risk organism BSI (gram-negative and Staphylococcus aureus BSI), as well as model calibration. RESULTS: In 2,565 evaluable episodes, the BSI rate was 4.7% (N = 120). Complications for the whole cohort were rare, with 1.1% (N = 27) needing intensive care unit (ICU) care by 7 days, and the all-cause mortality rate was 0.2% (N = 5), with only one potential infection-related death. C-statistics ranged from 0.775 to 0.789 for predicting overall BSI, with improved accuracy in predicting high-risk organism BSI (C-statistic 0.800-0.819). Initial empiric antibiotics were withheld in 14.9% of episodes, with no deaths or ICU admissions attributable to not receiving empiric antibiotics. CONCLUSION: The EsVan models, especially EsVan2b, perform very well prospectively across multiple academic medical centers and accurately stratify risk of BSI in episodes of non-neutropenic fever in pediatric patients with cancer. Implementation of routine screening with risk-stratified management for non-neutropenic fever in pediatric patients with cancer could safely reduce unnecessary antibiotic use.

RESUMEN

Testicular tumors are relatively rare in children and those in prepubertal children tend to present with different histological types and behaviors than their postpubertal counterparts. The majority of these pre- and peripubertal testicular tumors tend to be benign and those that are malignant, tend to present at low stages, not generally requiring systemic treatment. Here we present a rare case of a peri-pubertal, mixed nonseminomatous germ cell tumor of the testes which was found to be widely metastatic at presentation, classifying as poor risk disease.

RESUMEN

Sexual health (SH), an integral aspect of overall health and quality of life, can be negatively affected by cancer and cancer treatment. SH is influenced by biological, psychological, social, and cultural factors, and, for adolescents and young adults (AYAs), developmental factors. The AYA population (age 15-39 years) is diverse in terms of psychosexual development, interpersonal relationships, and varying levels of independence, resulting in unique SH needs for this population. AYAs with cancer are particularly vulnerable to unmet SH needs related to contraception and infection prevention, sexual function, body image, and romantic/sexual relationships. Sexual dysfunction during and after cancer treatment is reported by 30%-100% of AYA cancer survivors. Clinical guidelines recommend discussing SH and screening for dysfunction but currently lack specifics regarding psychosexual interventions and strategies for incorporating screening into clinical care. Research and clinical priorities include improved provider-AYA communication regarding SH, standardization of SH measures and screening tools, infrastructure to support the SH needs of AYAs across pediatric and adult clinical environments, and engagement of sexual and gender minority AYAs in research. As the field of SH in cancer evolves, interventions need to be tailored to the developmental needs that are unique to AYAs and address the multidimensional aspects of SH.

RESUMEN

BACKGROUND: Positron emission tomography (PET) scans are used in disease diagnosis and evaluation for pediatric oncology patients. Brown adipose tissue (BAT) 18 F-fluorodeoxyglucose-PET uptake is reported in 35% to 47% of pediatric patients. Several risk factors may be associated with BAT uptake. OBJECTIVE: The aim was to determine the incidence and risk factors for BAT in pediatric patients using a consensus-based system and a novel grading scale. METHODS: A total of 285 PET scans in 154 patients were retrospectively reviewed for the presence of BAT from September 2015 through December 2016. A consensus review was done by 2 radiologists, who graded BAT on a 0 to 3 scale and assessed its impact on PET interpretation. RESULTS: The presence of moderate to severe BAT occurred in 11% of PET scans, and 6% of PETs had limited interpretation. Hodgkin lymphoma (n=53) patients had a 3.62-fold increased odds of moderate or severe BAT and a 6.59-fold increased odds of limited interpretation on PET imaging. CONCLUSION: The incidence of BAT was low but impacted radiologic interpretation when present. Further studies with a larger group of Hodgkin lymphoma patients are needed to explore the risk factors associated with moderate or severe BAT.

RESUMEN

PURPOSE: Febrile neutropenia (FN) in pediatric patients with cancer can cause severe infections, and prompt antibiotics are warranted. Extrapolated from other populations, a time-to-antibiotic (TTA) metric of <60 minutes after medical center presentation was established, with compliance data factoring into pediatric oncology program national rankings. METHODS: All FN episodes occurring at Vanderbilt Children's Hospital (2007-February 2022) and a sample of episodes from Colorado Children's Hospital (2012-2019) were abstracted, capturing TTA and clinical outcomes including major complications (intensive care unit [ICU] admission, vasopressors, intubation, or infection-related mortality). Odds ratios (ORs) were adjusted for age, treatment center, absolute neutrophil count, hypotension presence, stem-cell transplant status, and central line type. RESULTS: A total of 2,349 episodes were identified from Vanderbilt (1,920) and Colorado (429). Only 0.6% (n = 14) episodes required immediate ICU management, with a median TTA of 28 minutes (IQR, 20-37). For the remaining patients, the median TTA was 56 minutes (IQR, 37-90), and 54.3% received antibiotics in <60 minutes. There were no significant associations between TTA (<60 or ≥60 minutes) and major complications (adjusted OR, 0.99 [95% CI, 0.62 to 1.59]; P = .98), and a TTA ≥60 minutes was not associated with any type of complication. Similarly, TTA, when evaluated as a continuous variable, was not associated with a major (OR, 0.99 [95% CI, 0.94 to 1.04]; P = .69) nor any other complication in adjusted analysis. CONCLUSION: There is no clear evidence that a reduced TTA improves clinical outcomes in pediatric oncology FN and thus it should not be used as a primary quality measure.

RESUMEN

INTRODUCTION: Female cancer survivors who received gonadotoxic cancer treatment are at risk for profound diminished ovarian reserve and/or primary ovarian insufficiency with resulting infertility, which can be associated with distress and decreased quality of life.. Despite prioritizing future parenthood, many survivors are unsure of the impact of their treatment on their future fertility, and little is known about the perceived reproductive health needs and factors associated with receipt of a fertility status assessment (FSA). There is a lack of developmentally appropriate reproductive health decisional support interventions available for emerging adult cancer survivors. This study will explore the perceived reproductive health needs of emerging adult female survivors of childhood cancer and to identify decisional and contextual factors that influence pursuit of FSA using an explanatory sequential quantitative to qualitative mixed methods design. METHODS AND ANALYSIS: This study will enroll 325 female survivors (aged 18 to 29 years and >1-year post treatment; diagnosed with cancer < age 21 years) from four cancer centers in the United States. Sociodemographic and developmental factors, reproductive knowledge and values, decisional needs, and receipt of an FSA will be assessed through a web-based survey. Informed by survey findings, a subset of participants will be recruited for qualitative interviews to explore decisional factors associated with uptake of an FSA. Clinical data will be abstracted from the medical records. Multivariable logistic regression models will be developed to identify factors associated with FSA and qualitative descriptive analysis will be used to develop themes from the interviews. Quantitative and qualitative findings will be merged using a joint display to develop integrated study conclusions and direct future interventional research.

RESUMEN

PURPOSE: To better understand preferences and attitudes that adult-aged survivors of childhood cancer have toward survivorship care plans (SCP) and related SCP-based counseling. METHODS: Semi-structured qualitative interviews were conducted with 20 survivors participating in the Childhood Cancer Survivor Study who were at increased risk for cardiovascular disease secondary to their original cancer treatment. All participants were part of a larger randomized clinical trial (NCT03104543) testing the efficacy of an SCP-based counseling intervention with goal-setting designed to improve control of cardiovascular risk factors (i.e., hypertension, dyslipidemia, diabetes). A primarily deductive thematic analysis methodology guided interpretation; coded interview segments were grouped into primary themes of facilitators, barriers, suggestions, and positive sentiments. RESULTS: Participants described benefits of the intervention including facilitation of accountability, goal-setting, and increased knowledge of their health. Many participants also noted improved knowledge of their cancer treatment and subsequent risks, and they were interested in sharing this information with their primary care provider. However, several participants were disappointed when they did not achieve their goals or felt that they had low motivation. Participants generally wanted increased flexibility in the intervention, whether in the duration, frequency, or method of delivery. CONCLUSIONS: The SCP-based intervention was generally well-received by those interviewed and appears promising for promoting goal-setting and accountability as part of an SCP-based intervention to improve control of cardiovascular risk factors. IMPLICATIONS FOR CANCER SURVIVORS: Many survivors are at risk for cardiovascular disease or other potentially modifiable effects of their treatment. SCP-based interventions may facilitate improved control of these late effects.

RESUMEN

Extracranial malignant rhabdoid tumors (MRT) are very rare and aggressive tumors. They are typically associated with an extremely poor prognosis, particularly when seen in the infant and neonatal population. Here we present the case of a newborn female born with a large vaginal mass and evidence of prenatal lower urinary tract obstruction that was determined to be a MRT of vaginal origin. In this report, we will also discuss an overview of extracranial MRT tumor biology and treatment considerations.

RESUMEN

Transient hyperglycemia during induction chemotherapy is associated with increased morbidity and mortality in patients with acute lymphoblastic leukemia (ALL). Treatment with glucocorticoids, asparaginase, and stress are the proposed causal factors. Although these risks are not exclusive to induction, glycemic control throughout the remainder of ALL/lymphoma (ALL/ALLy) therapy has not been described. Furthermore, prior research has been limited to transient hyperglycemia. This study aimed to characterize glycemic control throughout ALL/ALLy and to evaluate risk factors and outcomes associated with increased mean glucose and glucose coefficient of variation (glucose CV) during induction chemotherapy. The records for 220 pediatric/young adult patients, age 1 to 26 years, who underwent treatment for ALL/ALLy from 2010 to 2014 at Children's Hospital Colorado were retrospectively reviewed. Measures of glycemic control were calculated for each cycle. For the cycle with the highest mean glucose, induction (n=208), multivariable models were performed to identify potential risk factors and consequences of increased glucose. Highest mean glucose by cycle were induction 116 mg/dL, pretreatment 108 mg/dL, delayed intensification 96 mg/dL, and maintenance 93 mg/dL; these cycles also had the most glycemic variability. During induction, patients with Down syndrome, or who were ≥12 years and overweight/obese, had higher mean glucoses; age and overweight/obese status were each associated with increased glucose CV. In multivariable analysis, neither induction mean glucose nor glucose CV were associated with increased hazard of infection, relapse, or death.
