MHealth Apps in the Digital Marketplace for Pediatric Patients With Cancer: Systematic Search and Analysis.

The substantial increase in smartphone ownership has led to a rise in mobile health (mHealth) app use. Developing tailored features through mHealth apps creates a pathway to address the health care needs of pediatric patients with cancer and their families who have complex care needs. However, few apps are designed specifically to integrate with pediatric cancer care. This study reports a systematic search and analysis of mHealth apps available on the Apple App (iOS) and Google Play (Android) stores designed for pediatric cancer through a list of features that serve (1) patients, (2) caregivers, or (3) both audiences. Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we reviewed apps for pediatric patients with cancer and caregivers available as of January 30, 2024. We searched the Apple App and Google Play stores with a list of keyword combinations focusing on pediatric cancer care. The inclusion criteria were (1) specifically apps targeted toward pediatric patients with cancer, their families, or both; (2) available in either app store; and (3) available in English. Apps were assessed using the Mobile Application Rating Scale (MARS). The MARS is a quality assessment for mHealth apps, including components of engagement, functionality, aesthetics, and informational quality (5-point Likert scale items-1: low and 5: high quality). In total, 22 apps were identified and 17 of those apps were available on both platforms. The most popular features (n=12) were resource sharing, symptom tracking, reminders, care team connections, journaling, community support, medication tracking, data visualizations, and appointment tracking. Features and interfaces were designed for caregivers (n=9) more frequently than the patients (n=7) while a subset of apps created options for both users (n=6). A total of 16 apps received positive reviews (mean 4.4, SD 0.59; Min=3.1, Max=5.0). A small subset (n=3) achieved over 5000 downloads; however, the majority (n=15) had fewer than 500. More than half (n=12) of the apps were not available in English. Apps requested access to a range of device functionalities to operate (mean 2.72, SD 3.13; Min=0, Max=10). Out of 22, a total of 17 apps were publicly accessible. The mean MARS scores for the apps ranged from 1.71 (SD 0.75) to 4.33 (SD 0.82). Overall, apps scored high on functionality (mean 3.72, SD 0.54) but low on engagement (mean 3.02, SD 0.93). Our review highlights the promising yet underdeveloped potential of mHealth apps in pediatric oncology care, underscoring the need for more inclusive, comprehensive, and integrative digital health solutions. Future developments should actively involve key stakeholders from the pediatric oncology community, including patients, families, and health care professionals, to ensure the apps meet specific needs while addressing linguistic and cultural barriers.

The TeLeo Program: Tele-education in pediatric oncology as a tool to support training programs in Latin America.

The TeLeo Program offers a free-access 2-year online learning program to support fellowship programs in pediatric oncology, enhance networking opportunities, and facilitate the exchange of context-specific, educational content within the pediatric oncology community in training in Latin America. In its first edition beginning in 2021, 185 fellows from 40 centers in 12 Latin American countries were enrolled. Additional courses for other healthcare professionals related to oncology in the region were produced to further support the program. A digital platform was created to allow users to easily access learning activities after registration, with 7075 professionals currently registered.

Collaborative Innovations in Childhood Cancer Therapies.

The outcome for children with cancer has improved significantly over the past 60years, with more than 80% of patients today becoming 5-year survivors. Despite this progress, cancer remains the leading cause of death from disease in children in the United States and Europe, with significant short- and long-term toxicity of treatment continuing to impact most children. While the past 15years have witnessed dramatic scientific innovation for certain cancers in adult patients, pediatric cancer treatment innovation lags increasingly behind. To help bridge the adult-pediatric therapeutic development gap, collaborative efforts are essential among stakeholders within and outside the pediatric oncology community. Prioritizing collaboration in areas such as cancer characterization, target identification and validation, drug discovery, and approaches to currently "undruggable" targets is imperative to improving the outcomes for children with cancer.

Being diagnosed with a rhabdomyosarcoma in the era of artificial intelligence: Whom can we trust?

In the era of big data, young patients may be overwhelmed by artificial intelligence-based tools, like chatbots. Five clinical experts were asked to evaluate the performance of the most currently used chatbots in providing information on a rare cancer affecting young people, like rhabdomyosarcoma. Generally speaking, despite their high performance in giving general information about the disease, these chatbots were considered by the experts to be inadequate in providing suggestions on cancer treatments and specialized centers, and also lacking in "sensitivity." Efforts are planned by the pediatric oncology community to improve the quality of data used to train these tools.

Exploring the interagency collaboration between a pediatric oncology health care setting and community schools.

Globally, approximately 400,000 youth are diagnosed with pediatric cancer each year. Treatment-related side effects, psychosocial challenges, and frequent school absences may adversely impact learning and the education experience among these youth. Efforts to enhance interagency collaboration between health care settings and community schools are imperative to facilitate school reintegration. The Standards for the Psychosocial Care of Children with Cancer and Their Families outline specific guidelines related to the continuity of education for students impacted by pediatric cancer. In particular, the Academic Continuity and School Reentry Support and Monitoring and Assessment of Neuropsychological Outcomes standards of care highlighted within this article align with extant programmatic efforts for transitioning hospitalized school-aged children back into community schools. This article aims to describe systematic programmatic efforts within hospital-based psychosocial programs that are consistent with the Standards for the Psychosocial Care of Children with Cancer and Their Families, as well as interagency collaboration with community schools to support student-centered education for youth impacted by pediatric cancer. Resources for school psychologists, teachers, hospital-based programs, and others involved in student-centered education for pediatric cancer patients and survivors are presented.

Childhood cancer data initiative: Status report.

In March 2023, over 800 researchers, clinicians, patients, survivors, and advocates from the pediatric oncology community met to discuss the progress of the National Cancer Institute's Childhood Cancer Data Initiative. We present here the status of the initiative's efforts in building its data ecosystem and updates on key programs, especially the Molecular Characterization Initiative and the planned Coordinated National Initiative for Rare Cancers in Children and Young Adults. These activities aim to improve access to childhood cancer data, foster collaborations, facilitate integrative data analysis, and expand access to molecular characterization, ultimately leading to the development of innovative therapeutic approaches.

Unprecedented Living Lab Approach: Technological Innovations for Paediatric Cancer Support System

The paediatric oncology field still faces significant challenges, despite the substantial progress in childhood cancer diagnosis and treatment. Not only in terms of incidence and mortality rate reduction but also in terms of patients, their support system (e.g. family, school staff) and the cancer survivors’ well-being. The use of innovation has provided new forms to support the paediatric oncology community. As these solutions continue to emerge it is necessary to test and validate them based on the end-users’ specific needs. In this context, this article shares the ongoing work in the development of an unprecedented and unique Living Lab project. In this ecosystem, a paediatric oncology patients' physiological monitoring device, an app that combines technology and science with culture and arts to create mental health promotion solutions device, a virtual reality solution to help paediatric oncology patients manage pain via gamified environments and a methodology to diagnose difficulties in problem-solving that arise among parents and caregivers of children with cancer survivors, breakthroughs technologies where supported and leveraged during their participation in this Living Lab program. Considering the symbiotic interdependence between end-users empowered by Living Labs and the Living Labs’ success dependency on the end-users involvement and motivation, an original methodology for entrepreneurship fostering and innovation support based on end-user participants’ high involvement was proposed and evaluated. This methodology was based on interlinked and tailored sessions which were characteristically re-designed based on the stage of development of the proposed innovation, the technical support required and the end-users' needs and engagement level as well as the feedback obtained from previous activities. As a result of the complexity of the context in which the solutions are implemented and the changing openness and engagement of the end-users, the activities and sessions were constantly being created and customized. Although this is a work-in-progress, the tailored engagement program developed already allowed the value creation for all the participants and an efficient evaluation and validation of new end-user-centred solutions which will harness progress through their path to the market.

Identification of Pediatric Tumors Intraoperatively Using Indocyanine Green (ICG).

Fluorescence-guided surgery (FGS) with indocyanine green (ICG) is increasingly applied in pediatric surgical oncology. However, FGS has been mostly reported in case studies of liver or renal tumors. Applying novel technologies in pediatric surgical oncology is more challenging than in adult surgical oncology due to differences in tumor histology, biology, and fewer cases. No consensus exists on ICG-guided FGS for surgically managing pediatric solid tumors. Therefore, we reviewed the literature and discuss the limitations and prospects of FGS. Using PRISMA guidelines, we analyzed articles on ICG-guided FGS for childhood solid tumors. Case reports, opinion articles, and narrative reviews were excluded. Of the 108 articles analyzed, 17 (14 retrospective and 3 prospective) met the inclusion criteria. Most (70.6%) studies used ICG to identify liver tumors, but the timing and dose of ICG administered varied. Intraoperative outcomes, sensitivity and specificity, were reported in 23.5% of studies. Fluorescence-guided liver resections resulted in negative margins in 90-100% of cases; lung metastasis was detected in 33% of the studies. In otolaryngologic malignancies, positive margins without fluorescence signal were reported in 25% of cases. Overall, ICG appeared effective and safe for lymph node sampling and nephron-sparing procedures. Despite promising results from FGS, ICG use varies across the international pediatric surgical oncology community. Underreported intraoperative imaging outcomes and the diversity and rarity of childhood solid tumors hinder conclusive scientific evidence supporting adoption of ICG in pediatric surgical oncology. Further international collaborations are needed to study the applications and limitations of ICG in pediatric surgical oncology.

OpenPBTA: The Open Pediatric Brain Tumor Atlas

Pediatric brain and spinal cancers are collectively the leading disease-related cause of death in children; thus, we urgently need curative therapeutic strategies for these tumors. To accelerate such discoveries, the Children's Brain Tumor Network (CBTN) and Pacific Pediatric Neuro-Oncology Consortium (PNOC) created a systematic process for tumor biobanking, model generation, and sequencing with immediate access to harmonized data. We leverage these data to establish OpenPBTA, an open collaborative project with over 40 scalable analysis modules that genomically characterize 1,074 pediatric brain tumors. Transcriptomic classification reveals universal TP53 dysregulation in mismatch repair-deficient hypermutant high-grade gliomas and TP53 loss as a significant marker for poor overall survival in ependymomas and H3 K28-mutant diffuse midline gliomas. Already being actively applied to other pediatric cancers and PNOC molecular tumor board decision-making, OpenPBTA is an invaluable resource to the pediatric oncology community.

The international scandal of defective asparaginase: A blight on children with cancer.

Acute lymphoblastic leukemia is the commonest form of cancer in children and adolescents worldwide, and asparaginase is an essential component of successful chemotherapy for this disease associated with long-term survival rates often exceeding 90% in high-income countries. Demonstrably defective preparations of asparaginase, distributed from China and India, increase the burden of morbidity and mortality, reducing attainable survival rates. This adverse outcome is enabled by inadequate regulation and oversight, especially in resource-poor settings in low- and middle-income countries where the great majority of children and adolescents with cancer live. The pediatric oncology community must rise to the challenge.

Cardiac Disease in Childhood Cancer Survivors Treated With Radiation Therapy: A PENTEC Comprehensive Review

Radiation therapy (RT) is an essential component in the treatment of many pediatric malignancies. Thoracic RT may expose the heart to radiation dose and thereby increase the risk of late cardiac disease. This comprehensive review from the Pediatric Normal Tissue Effects in the Clinic (PENTEC) initiative focused on late cardiac disease in survivors of childhood cancer treated with RT. This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. We identified 1496 articles; 4 were included for dose-response modeling between mean cardiac radiation dose and risk of late coronary artery disease, heart failure (HF), valvular disease, and any cardiac disease. For each 10-Gy increase in corrected mean cardiac radiation dose in 1.8- to 2.0-Gy fractions, we estimated a hazard ratio of 2.01 (95% confidence interval [CI], 1.79-2.25) for coronary artery disease, of 1.87 (95% CI, 1.70-2.06) for HF, of 1.87 (95% CI, 1.78-1.96) for valvular disease, and of 1.88 (95% CI, 1.75-2.03) for any cardiac disease. From the same model, for each 100-mg/m2 increase in cumulative anthracycline dose, the hazard ratio for the development of HF was 1.93 (95% CI, 1.58-2.36), equivalent to an increase in mean heart dose of approximately 10.5 Gy. Other nontreatment factors were inconsistently reported in the analyzed articles. Radiation dose to the heart increases the risk of late cardiac disease, but survivors of childhood cancer who receive a mean dose <10 Gy at standard fractionation are at low absolute risk (<∼2% approximately 30 years after exposure) of late cardiac disease in the absence of anthracycline exposure. Minimizing cardiac radiation dose is especially relevant in children receiving anthracyclines. When cardiac sparing is not possible, we recommend prioritizing target coverage. It is likely that individual cardiac substructure doses will be a better predictor of specific cardiac diseases than mean dose, and we urge the pediatric oncology community to further study these relationships.

Pediatric diffuse midline glioma H3K27- altered: A complex clinical and biological landscape behind a neatly defined tumor type.

The 2021 World Health Organization Classification of Tumors of the Central Nervous System, Fifth Edition (WHO-CNS5), has strengthened the concept of tumor grade as a combination of histologic features and molecular alterations. The WHO-CNS5 tumor type "Diffuse midline glioma, H3K27-altered," classified within the family of "Pediatric-type diffuse high-grade gliomas," incarnates an ideally perfect integrated diagnosis in which location, histology, and genetics clearly define a specific tumor entity. It tries to evenly characterize a group of neoplasms that occur primarily in children and midline structures and that have a dismal prognosis. Such a well-defined pathological categorization has strongly influenced the pediatric oncology community, leading to the uniform treatment of most cases of H3K27-altered diffuse midline gliomas (DMG), based on the simplification that the mutation overrides the histological, radiological, and clinical characteristics of such tumors. Indeed, multiple studies have described pediatric H3K27-altered DMG as incurable tumors. However, in biology and clinical practice, exceptions are frequent and complexity is the rule. First of all, H3K27 mutations have also been found in non-diffuse gliomas. On the other hand, a minority of DMGs are H3K27 wild-type but have a similarly poor prognosis. Furthermore, adult-type tumors may rarely occur in children, and differences in prognosis have emerged between adult and pediatric H3K27-altered DMGs. As well, tumor location can determine differences in the outcome: patients with thalamic and spinal DMG have significantly better survival. Finally, other concomitant molecular alterations in H3K27 gliomas have been shown to influence prognosis. So, when such additional mutations are found, which one should we focus on in order to make the correct clinical decision? Our review of the current literature on pediatric diffuse midline H3K27-altered DMG tries to address such questions. Indeed, H3K27 status has become a fundamental supplement to the histological grading of pediatric gliomas; however, it might not be sufficient alone to exhaustively define the complex biological behavior of DMG in children and might not represent an indication for a unique treatment strategy across all patients, irrespective of age, additional molecular alterations, and tumor location.

Implementation of a provider-focused intervention for maximizing human papillomavirus (HPV) vaccine uptake in young cancer survivors receiving follow-up care in pediatric oncology practices: protocol for a cluster-randomized trial of the HPV PROTECT intervention

BackgroundChildhood cancer survivors are at high risk for developing new cancers (such as cervical and anal cancer) caused by persistent infection with the human papillomavirus (HPV). HPV vaccination is effective in preventing the infections that lead to these cancers, but HPV vaccine uptake is low among young cancer survivors. Lack of a healthcare provider recommendation is the most common reason that cancer survivors fail to initiate the HPV vaccine. Strategies that are most successful in increasing HPV vaccine uptake in the general population focus on enhancing healthcare provider skills to effectively recommend the vaccine, and reducing barriers faced by the young people and their parents in receiving the vaccine. This study will evaluate the effectiveness and implementation of an evidence-based healthcare provider-focused intervention (HPV PROTECT) adapted for use in pediatric oncology clinics, to increase HPV vaccine uptake among cancer survivors 9 to 17 years of age.MethodsThis study uses a hybrid type 1 effectiveness-implementation approach. We will test the effectiveness of the HPV PROTECT intervention using a stepped-wedge cluster-randomized trial across a multi-state sample of pediatric oncology clinics. We will evaluate implementation (provider perspectives regarding intervention feasibility, acceptability and appropriateness in the pediatric oncology setting, provider fidelity to intervention components and change in provider HPV vaccine-related knowledge and practices [e.g., providing vaccine recommendations, identifying and reducing barriers to vaccination]) using a mixed methods approach.DiscussionThis multisite trial will address important gaps in knowledge relevant to the prevention of HPV-related malignancies in young cancer survivors by testing the effectiveness of an evidence-based provider-directed intervention, adapted for the pediatric oncology setting, to increase HPV vaccine initiation in young cancer survivors receiving care in pediatric oncology clinics, and by procuring information regarding intervention delivery to inform future implementation efforts. If proven effective, HPV PROTECT will be readily disseminable for testing in the larger pediatric oncology community to increase HPV vaccine uptake in cancer survivors, facilitating protection against HPV-related morbidities for this vulnerable population.Trial registrationClinicalTrials.gov Identifier: NCT04469569, prospectively registered on July 14, 2020.

FDA analysis of expanded access use in pediatric patients from 2015 to 2020.

1529 Background: Expanded Access is a regulatory mechanism that enables patients with a life-threatening condition or serious disease to receive treatment with an investigational drug outside of a clinical trial when no comparable or satisfactory alternative options are available. FDA has decades of experience with expanded access, but little has been reported about its use in pediatric cancer patients. Methods: FDA’s central electronic database was queried for single-patient investigational new drug (spIND) applications submitted to the Office of Oncologic Diseases between January 2015 through December 2020. Data collection included IND receipt date, IND type/status, drug name, and patient demographics. Duplicate or exempt INDs, those cancelled by the physician-sponsor before initiating therapy, and those requested for indications that occur almost exclusively in adults (e.g. lung cancer) or were missing patient age were excluded. Results: Of 2,901 unique spINDs granted, 534 (18%) were for patients less than 18 years of age. The pediatric population was 57% male, median age 6.0 years (range 0.1 to 17); race/ethnicity were reported in &lt;1%. Patients were treated in 132 zip codes across 39 states; one-quarter of submissions were from 5 large academic hospitals. Central nervous system tumors were the most common indication (Table 1). A total of 98 unique drugs were requested, with 1 to 73 spINDs for each drug; approximately 50% were for tyrosine kinase inhibitors, 25% for other small molecules, and the remainder for immunotherapies and other drug types. Median time for FDA to grant was 1 day. Follow-up information was provided for 75% (annual report or withdrawal letter); 1/3 were withdrawn within 1 year. Over the last 2 years, utilization of the program increased by 120%. Conclusions: While approximately 1% of all cancers per year are diagnosed in children under 17 years of age, 18% of spINDs over the last five years were for pediatric patients. Although utilization of this program for children is robust, efforts are needed to assess its impact on patient outcomes and ensure its availability to patients, families, and institutions more widely. These data highlight interest within the pediatric oncology community in accessing innovative therapies, which supports early investigation of promising new drugs in children.[Table: see text]

Caring for children with cancer evacuated from Ukraine

Since the war in Ukraine started on Feb 24, 2022, thousands of children and civilians have been killed, and the resulting humanitarian crisis is one of the worst that Europe has experienced in recent times. Among the 2 million child refugees who fled Ukraine, children and adolescents with cancer are facing particular challenges as their treatment is interrupted by the war. The international paediatric oncology community has been trying to find ways and resources to deal with a new emergency—to continue care provision for these patients.

Perspectives and Expertise in Establishing a Therapeutic Drug Monitoring Programme for Challenging Childhood Cancer Patient Populations.

The utility of Therapeutic Drug Monitoring (TDM) in the setting of childhood cancer is a largely underused tool, despite the common use of cytotoxic chemotherapeutics. While it is encouraging that modern advances in chemotherapy have transformed outcomes for children diagnosed with cancer, this has come at the cost of an elevated risk of life-changing long-term morbidity and late effects. This concern can limit the intensity at which these drugs are used. Widely used chemotherapeutics exhibit marked inter-patient variability in drug exposures following standard dosing, with fine margins between exposures resulting in toxicity and those resulting in potentially suboptimal efficacy, thereby fulfilling criteria widely accepted as fundamental for TDM approaches. Over the past decade in the UK, the paediatric oncology community has increasingly embraced the potential benefits of utilising TDM for particularly challenging patient groups, including infants, anephric patients and those receiving high dose chemotherapy. This has been driven by a desire from paediatric oncologists to have access to clinical pharmacology information to support dosing decisions being made. This provides the potential to modify doses between treatment cycles based on a comprehensive set of clinical information, with individual patient drug exposures being used alongside clinical response and tolerability data to inform dosing for subsequent cycles. The current article provides an overview of recent experiences of conducting TDM in a childhood cancer setting, from the perspectives of the clinicians, scientists and pharmacists implementing TDM-based dosing recommendations. The ongoing programme of work has facilitated investigations into the validity of current approaches to dosing for some of the most challenging childhood cancer patient groups, with TDM approaches now being expanded from well-established cytotoxic drugs through to newer targeted treatments.

Pediatric Cancer Data Commons: Federating and Democratizing Data for Childhood Cancer Research.

The international pediatric oncology community has a long history of research collaboration. In the United States, the 2019 launch of the Children's Cancer Data Initiative puts the focus on developing a rich and robust data ecosystem for pediatric oncology. In this spirit, we present here our experience in constructing the Pediatric Cancer Data Commons (PCDC) to highlight the significance of this effort in fighting pediatric cancer and improving outcomes and to provide essential information to those creating resources in other disease areas. The University of Chicago's PCDC team has worked with the international research community since 2015 to build data commons for children's cancers. We identified six critical features of successful data commons design and implementation: (1) establish the need for a data commons, (2) develop and deploy the technical infrastructure, (3) establish and implement governance, (4) make the data commons platform easy and intuitive for researchers, (5) socialize the data commons and create working knowledge and expertise in the research community, and (6) plan for longevity and sustainability. Data commons are critical to conducting research on large patient cohorts that will ultimately lead to improved outcomes for children with cancer. There is value in connecting high-quality clinical and phenotype data to external sources of data such as genomic, proteomics, and imaging data. Next steps for the PCDC include creating an informed and invested data-sharing culture, developing sustainable methods of data collection and sharing, standardizing genetic biomarker reporting, incorporating radiologic and molecular analysis data, and building models for electronic patient consent. The methods and processes described here can be extended to any clinical area and provide a blueprint for others wishing to develop similar resources.
