Quality of life of adolescent and adult survivors of childhood cancer in Europe-A systematic review.

Advances in diagnostics and treatment of childhood cancer during the past few decades have substantially increased survival, resulting in a growing population of survivors of childhood cancer. Somatic and mental late effects of the cancer and the treatment may impact the quality of life (QoL). Previous reviews of QoL in survivors of childhood cancer have shown contradictory findings across studies and the majority of studies included have been based on data from North America and may not be directly comparable to a European setting. The aim of our study was to critically evaluate and summarise the latest evidence on the QoL of childhood cancer survivors in Europe and to identify survivors at particular risk. The eligible studies were published between 2008 and 2022, conducted in Europe and included participants who had survived at least 5 years after diagnosis of a childhood cancer. The main outcome of interest was QoL of survivors which was measured with validated qualitative and quantitative QoL questionnaires. A systematic literature search conducted in PubMed, EMBASE, PsycINFO and CINALH resulted in inclusion of 36 articles with a total of 14 342 survivors of childhood cancer. The majority of included studies found that childhood cancer survivors reported poorer QoL than comparisons. Female gender, treatment with haematopoietic stem cell transplantation and a brain tumour diagnosis were associated with lower QoL. With a growing population of childhood cancer survivors with many years ahead of them, targeted interventions and optimal follow-up care are important to improve the QoL of survivors.

Everyday life during the childhood cancer trajectory-childhood cancer survivors' descriptions of the role of caring support.

Being diagnosed with cancer in childhood often has a direct impact on the child's opportunities to participate in activities and the child's sense of belonging in different life situations. Experiences of illness in youth affect the lives of these individuals in numerous ways and they need pronounced support to regain their normal life after treatment. To illustrate how childhood cancer survivors describe the role of the caring support provided by healthcare professionals at diagnosis and during the cancer trajectory. A mixed methods approach was applied. Swanson's Theory of Caring was used to deductively analyze the answers in a study-specific questionnaire with Likert scales (1-5). Descriptive and comparative statistics and exploratory factor analyses were performed. Sixty-two former patients, diagnosed with solid tumors/lymphoma in 1983 to 2003 in Sweden, participated. The mean time passed since treatment was 15.7 years. Swanson's caring processes Being with and Doing for were the most prominent loading categorical factor indicators. Higher scores for healthcare professionals being emotionally present (Being with), doing for others what they would do for themselves (Doing for) and being willing to understand the sick child's situation (Knowing) were highlighted by survivors older than 30 years, compared to those younger than 30 years (p = 0.041, p = 0.045, and p = 0.013, respectively). An increased vulnerability regarding their ability to cope with difficulties (Maintain belief) was found among participants who were treated during adolescence, related to schoolchildren (p = 0.048), and among those who had been treated with extra-cranial irradiation in comparison with no extra-cranial irradiation (p = 0.004). The role of having a partner in comparison with being single was underlined among those who felt they had acquired the tools they needed to take care of themselves (Enabling) (p = 0.013). The total explained variance was 63%. A person-centered care approach during treatment for childhood cancer, reflected by a caring model, highlights the role of healthcare professionals being emotionally present, involving children, performing actions, and with an approach that has potential long-term implications. Childhood cancer patients and survivors need not only clinically competent professionals, but professionals who provide caring interactions with compassion.

Local arterial stiffness measured by ultrafast ultrasound imaging in childhood cancer survivors treated with anthracyclines.

There is conflicting literature regarding the long-term effect of anthracycline treatment on arterial stiffness. This study assessed local arterial stiffness using ultrafast ultrasound imaging (UUI) in anthracycline treated childhood cancer survivors, at rest and during exercise. 20 childhood cancer survivors (mean age 21.02 ± 9.45 years) treated with anthracyclines (mean cumulative dose 200.7 ± 126.80 mg/m2) and 21 healthy controls (mean age 26.00 ± 8.91 years) were included. Participants completed a demographic survey, fasting bloodwork for cardiovascular biomarkers, and performed a submaximal exercise test on a semi-supine bicycle. Pulse wave velocity (PWV) was measured in the left common carotid artery by direct pulse wave imaging using UUI at rest and submaximal exercise. Both PWV at the systolic foot (PWV-SF) and dicrotic notch (PWV-DN) were measured. Central (carotid-femoral) PWV was obtained by applanation tonometry. Carotid measurements were taken by conventional ultrasound. Measures were compared using two-tailed Students t-test or Chi-squared test, as appropriate. There was no statistically significant difference (p > 0.05) between childhood cancer survivors and healthy controls in demographic parameters (age, sex, weight, height, BMI), blood biomarkers (total cholesterol, triglycerides, LDL-c, HDL-c, hs-CRP, fasting glucose, insulin, Hb A1c), cardiovascular parameters (intima media thickness, systolic and diastolic blood pressure, heart rate, carotid diameters, distensibility) or PWV measured by UUI at rest or at exercise. There was also no difference in the cardiovascular adaptation between rest and exercise in the two groups (p > 0.05). Multivariate analysis revealed age (p = 0.024) and LDL-c (p = 0.019) to be significant correlates of PWV-SF in childhood cancer survivors, in line with previously published data. We did not identify a significant impact of anthracycline treatment in young survivors of childhood cancer on local arterial stiffness in the left common carotid artery as measured by UUI.

Cost of childhood cancer treatment in Ethiopia.

Despite the recent interest in expanding pediatric oncology units in Ethiopia, reflected in the National Childhood and Adolescent Cancer Control Plan (NCACCP), little is known about the cost of running a pediatric oncology unit and treating childhood cancers. We collected historical cost data and quantity of services provided for the pediatric oncology unit and all other departments in Tikur Anbessa Specialized Hospital (TASH) from 8 July 2018 to 7 July 2019, using a provider perspective and mixed (top-down and bottom-up) costing approaches. Direct costs (human resources, drugs, supplies, medical equipment) of the pediatric oncology unit, costs at other relevant clinical departments, and overhead cost share are summed up to estimate the total annual cost of running the unit. Further, unit costs were estimated at specific childhood cancer levels. The estimated annual total cost of running a pediatric oncology unit was USD 776,060 (equivalent to USD 577 per treated child). The cost of running a pediatric oncology unit per treated child ranged from USD 469 to USD 1,085, on the scenario-based sensitivity analysis. Drugs and supplies, and human resources accounted for 33% and 27% of the total cost, respectively. Outpatient department and inpatient department shared 37% and 63% of the cost, respectively. For the pediatric oncology unit, the cost per OPD visit, cost per bed day, and cost per episode of hospital admission were USD 36.9, 39.9, and 373.3, respectively. The annual cost per treated child ranged from USD 322 to USD 1,313 for the specific childhood cancers. Running a pediatric oncology unit in Ethiopia is likely to be affordable. Further analysis of cost effectiveness, equity, and financial risk protection impacts of investing in childhood cancer programs could better inform the prioritization of childhood cancer control interventions in the Ethiopia Essential Health Service Package.

Protective effect of the dexrazoxane against cardiotoxicity of the anthracycline in the treatment of the childhood cancers.

e22001 Background: Cardiovascular diseases have become the most important cause of morbidity and mortality in the long-term follow-up of childhood cancer survivors. Dexrazoxane (DEX) is the only FDA-approved drug to prevent Anthracycline-induced cardiotoxicity. In this study, we aimed to evaluate the cardioprotective efficacy of DEX in patients using Anthracycline in the treatment of childhood cancer. Methods: 142 patients aged 0-18 years, who were treated with cancer diagnosis in Ankara University Faculty of Medicine, Department of Pediatrics, Department of Pediatric Oncology, and who had been treated with Anthracycline group agents, were evaluated retrospectively. The cardiac functions of 87 patients who received only Anthracycline between November 2009 and March 2019 and 55 patients who received DEX + Anthracycline between March 2019 and June 2021 were compared. An ejection fraction (EF) of less than 50% in cardiac evaluation was defined as 'cardiac dysfunction'. Results: The group that received anthracycline with DEX; While 50.9% were girls, 49.1% were boys, and the mean age was 98.42 months, 48.3% of the group that took only Anthracycline was girls and 51.7% were boys, with a mean age of 105.75 months. There was no difference between the two groups in terms of diagnosis distribution. EF values of both groups before anthracycline were normal. While none of the patients in the DEX + Anthracycline group developed cardiac dysfunction during the follow-up, 11 (12.6%) patients in the Anthracycline group with no DEX had cardiac problems. Six Of the 11 patients (54.5%) who developed cardiac dysfunction died(p=0.012). There was a significant difference between the two groups with or without DEX patients in the manner of cardiac dysfunction(p=0.006) and death(p=0.009). Cardiac dysfunction development and mortality rates were higher in patients using only Anthracycline. Conclusions: In this study, it has been shown that DEX is very effective for preventing Anthracycline-related cardiac dysfunction, which is one of the most important causes of mortality and morbidity in childhood cancer survivors.

Cost and Cost-Effectiveness of Treating Childhood Cancer at Jimma Medical Center.

More than 70% of childhood cancer patients die in Sub-Saharan African countries due to a lack of access. Additionally establishing a childhood cancer treatment service is perceived as expensive by the decision-makers of LMICs. However, there is a paucity of evidence on the actual cost and cost-effectiveness of this service in LMICs including Ethiopia. This study provides context-relevant evidence to consider childhood cancer treatment in the healthcare priority settings in Ethiopia and other LMICs. Newly admitted case files of children for the year 2020/21 were reviewed. The cost was analyzed from the provider's perspective. The effectiveness was calculated using DALY averted based on the 5 years of survival rates, which is estimated from the 1-year survival rate of Kaplan-Meier output. The do-nothing was our comparator, and we assumed no cost (zero cost) will be incurred for the comparator. To account for sensitivity analyses, we varied the discount rate, 5-year survival rate, and life expectancy. During the study period, 101 children were treated in the unit. The total annual and unit cost to give treatment to childhood cancer patients was estimated at $279,648 and $2769, respectively. The highest per-patient annual unit cost of treatment was Hodgkin's lymphoma ($6252), while Retinoblastoma ($1520) was the least. The cost per DALY averted was $193, which is significantly less than Ethiopia's GDP per capita ($936.3). The results remained very cost-effective in sensitivity analyses. Childhood cancer treatment is very cost-effective in Ethiopia as per WHO-CHOICE thresholds even in a conservative adjustment of assumptions. Therefore, to enhance and improve children's health, childhood cancer should get a better concern in health priority.

A genome-wide association study for doxorubicin-induced cardiomyopathy in childhood cancer survivors from the St. Jude lifetime cohort (SJLIFE) and the childhood cancer survivor (CCSS) studies.

12088 Background: Treatment of childhood cancer using doxorubicin is associated with a well-established dose-related risk of cardiomyopathy, which can lead to heart failure and affects ~7-10% of exposed children and adolescents. Here, we identified a genetic variant associated with risk of doxorubicin-induced cardiomyopathy (diCM) in survivors of childhood cancer. Methods: A genome-wide association study using common variants (MAF≥5%; whole-genome sequencing data) was performed among 993 SJLIFE survivors of European ancestry (median age, 36.6 years; range, 8.7-62.2 years) treated with doxorubicin only (210 with diCM; defined as CTCAE grade ≥2 clinically assessed cardiomyopathy). Replication analyses were performed separately among 1,430 CCSS survivors of European ancestry (median age, 35.4 years; range, 15.8-60.7 years) and 159 SJLIFE survivors of African ancestry (median age, 32.6 years; range, 8.9-61.1 years) exposed to doxorubicin only. Analyses were adjusted for age at primary cancer diagnosis, sex, doxorubicin dose, age at last contact and top five principal components. Results: We identified a genome-wide significant association between a novel locus near HS3ST4 and diCM risk in SJLIFE survivors of European ancestry (rs112474856; OR = 2.78; P= 3.3×10-8). This association replicated in CCSS survivors of European ancestry (OR = 1.74, P= 0.036) but had an opposite effect among SJLIFE survivors of African ancestry (OR = 0.34, P= 0.028). SNP rs112474856 did not show significant association with diCM risk in two independent datasets including survivors of European ancestry in SJLIFE (OR = 1.20; P= 0.71) and CCSS (OR = 1.02; P= 0.98) who were not exposed to doxorubicin but were treated with daunorubicin or chest radiotherapy, suggesting doxorubicin specificity. No association was observed between rs112474856 and risks of cardiomyopathy (OR = 1.00; P= 0.88) or heart failure (OR = 1.00; P= 0.59) in 361,194 UK Biobank participants from the general population. HS3ST4 was significantly upregulated ( P= 4.7×10-6) in response to doxorubicin treatment in human induced pluripotent stem-cell-derived cardiomyocytes from patients with diCM. HS3ST4 encodes heparan sulfate, the latter was recently linked to immune activation, cardiac fibrosis, and heart failure. Conclusions: Leveraging the two largest cohorts of childhood cancer survivors in North America, we identified and replicated a novel locus for diCM which was associated with increased risk in survivors of European ancestry but decreased in their African counterpart.

Barriers and Facilitators to Implementing Cost-Effective Evidence-Based Childhood Cancer Treatment in a Resource-Limited Setting in Egypt: A Qualitative Interview Study.

Childhood cancer treatment is complex, resource-intensive, and expensive, and resource-limited settings would benefit from providing cost-effective treatment approaches on the basis of evidence. Effective implementation of cost-effective evidence-based treatment requires knowledge about factors influencing its use. In this study, we determined the clinicians' perceptions of the barriers and facilitators to implementing cost-effective evidence-based treatment for children with cancer in a resource-limited pediatric oncology setting in Egypt. We conducted a qualitative study on the basis of semistructured interviews with senior clinicians who make high-level decisions on treatment protocols and tailored decisions for the atypically complicated group of patients. Purposive sampling was used to recruit the participants. Thematic analysis was conducted semantically to develop themes of barriers and facilitators. Fourteen participants agreed to participate in the study: nine pediatric oncologists; three surgeons; and two radiation oncologists. We identified four main themes of barriers and facilitators: awareness and orientation; knowledge, skills, and attitudes; system, resources, and context; and clinical practice. The main barriers included absence of easily available costs/cost-effectiveness data, limited resources and inability to pay for expensive novel (cost-effective) drugs, and gap between evidence and practice. The main facilitators included adopting standard treatment protocols on the basis of clinical effectiveness, leadership support, availability of patients' clinical and cost data from local context, and existing knowledge and skills in clinical research and health economic evaluation. The interview participants also provided suggestions to promote the implementation of cost-effective evidence-based treatment in priority areas. Our study findings provide an understanding of the barriers and facilitators affecting the implementation of cost-effective evidence-based treatment for childhood cancers in Egypt. We provide practical recommendations to address the implementation gaps with implications on practice, policy, and research.

Cumulative burden of late, major surgical intervention in survivors of childhood cancer: a report from the Childhood Cancer Survivor Study (CCSS) cohort.

Multimodal cancer therapy places childhood cancer survivors at increased risk for chronic health conditions, subsequent malignancies, and premature mortality as they age. We aimed to estimate the cumulative burden of late (>5 years from cancer diagnosis), major surgical interventions among childhood cancer survivors, compared with their siblings, and to examine associations between specific childhood cancer treatments and the burden of late surgical interventions. We analysed data from the Childhood Cancer Survivor Study (CCSS), a retrospective cohort study with longitudinal prospective follow-up of 5-year survivors of childhood cancer (diagnosed before age 21 years) treated at 31 institutions in the USA, with a comparison group of nearest-age siblings of survivors selected by simple random sampling. The primary outcome was any self-reported late, major surgical intervention (defined as any anaesthesia-requiring operation) occurring 5 years or more after the primary cancer diagnosis. The cumulative burden was assessed with mean cumulative counts (MCC) of late, major surgical interventions. Piecewise exponential regression models with calculation of adjusted rate ratios (RRs) evaluated associations between treatment exposures and late, major surgical interventions. Between Jan 1, 1970, and Dec 31, 1999, 25 656 survivors were diagnosed (13 721 male, 11 935 female; median follow-up 21·8 years [IQR 16·5-28·4]; median age at diagnosis 6·1 years [3·0-12·4]); 5045 nearest-age siblings were also included as a comparison group. Survivors underwent 28 202 late, major surgical interventions and siblings underwent 4110 late, major surgical interventions. The 35-year MCC of a late, major surgical intervention was 206·7 per 100 survivors (95% CI 202·7-210·8) and 128·9 per 100 siblings (123·0-134·7). The likelihood of a late, major surgical intervention was higher in survivors versus siblings (adjusted RR 1·8, 95% CI 1·7-1·9) and in female versus male survivors (1·4; 1·4-1·5). Survivors diagnosed in the 1990s (adjusted RR 1·4, 95% CI 1·3-1·5) had an increased likelihood of late surgery compared with those diagnosed in the 1970s. Survivors received late interventions more frequently than siblings in most anatomical regions or organ systems, including CNS (adjusted RR 16·9, 95% CI 9·4-30·4), endocrine (6·7, 5·2-8·7), cardiovascular (6·6, 5·2-8·3), respiratory (5·3, 3·4-8·2), spine (2·4, 1·8-3·2), breast (2·1, 1·7-2·6), renal or urinary (2·0, 1·5-2·6), musculoskeletal (1·5, 1·4-1·7), gastrointestinal (1·4, 1·3-1·6), and head and neck (1·2, 1·1-1·4) interventions. Survivors of Hodgkin lymphoma (35-year MCC 333·3 [95% CI 320·1-346·6] per 100 survivors), Ewing sarcoma (322·9 [294·5-351·3] per 100 survivors), and osteosarcoma (269·6 [250·1-289·2] per 100 survivors) had the highest cumulative burdens of late, major surgical interventions. Locoregional surgery or radiotherapy cancer treatment were associated with undergoing late surgical intervention in the same body region or organ system. Childhood cancer survivors have a significant burden of late, major surgical interventions, a late effect that has previously been poorly quantified. Survivors would benefit from regular health-care evaluations aiming to anticipate impending surgical issues and to intervene early in the disease course when feasible.

A joint international consensus statement for measuring quality of survival for patients with childhood cancer.

The aim of treating childhood cancer remains to cure all. As survival rates improve, long-term health outcomes increasingly define quality of care. The International Childhood Cancer Outcome Project developed a set of core outcomes for most types of childhood cancers involving relevant international stakeholders (survivors; pediatric oncologists; other medical, nursing or paramedical care providers; and psychosocial or neurocognitive care providers) to allow outcome-based evaluation of childhood cancer care. A survey among healthcare providers (n = 87) and online focus groups of survivors (n = 22) resulted in unique candidate outcome lists for 17 types of childhood cancer (five hematological malignancies, four central nervous system tumors and eight solid tumors). In a two-round Delphi survey, 435 healthcare providers from 68 institutions internationally (response rates for round 1, 70-97%; round 2, 65-92%) contributed to the selection of four to eight physical core outcomes (for example, heart failure, subfertility and subsequent neoplasms) and three aspects of quality of life (physical, psychosocial and neurocognitive) per pediatric cancer subtype. Measurement instruments for the core outcomes consist of medical record abstraction, questionnaires and linkage with existing registries. This International Childhood Cancer Core Outcome Set represents outcomes of value to patients, survivors and healthcare providers and can be used to measure institutional progress and benchmark against peers.

Prognostic Factors for Cardiotoxicity among Children with Cancer: Definition, Causes, and Diagnosis with Omics Technologies.

Improvements in the treatment of childhood cancer have considerably enhanced survival rates over the last decades to over 80% as of today. However, this great achievement has been accompanied by the occurrence of several early and long-term treatment-related complications major of which is cardiotoxicity. This article reviews the contemporary definition of cardiotoxicity, older and newer chemotherapeutic agents that are mainly involved in cardiotoxicity, routine process diagnoses, and methods using omics technology for early and preventive diagnosis. Chemotherapeutic agents and radiation therapies have been implicated as a cause of cardiotoxicity. In response, the area of cardio-oncology has developed into a crucial element of oncologic patient care, committed to the early diagnosis and treatment of adverse cardiac events. However, routine diagnosis and the monitoring of cardiotoxicity rely on electrocardiography and echocardiography. For the early detection of cardiotoxicity, in recent years, major studies have been conducted using biomarkers such as troponin, N-terminal pro b-natriuretic peptide, etc. Despite the refinements in diagnostics, severe limitations still exist due to the increase in the above-mentioned biomarkers only after significant cardiac damage has occurred. Lately, the research has expanded by introducing new technologies and finding new markers using the omics approach. These new markers could be used not only for early detection but also for the early prevention of cardiotoxicity. Omics science, which includes genomics, transcriptomics, proteomics, and metabolomics, offers new opportunities for biomarker discovery in cardiotoxicity and may provide an understanding of the mechanisms of cardiotoxicity beyond traditional technologies.

Disparate Access to Fertility Preservation in Youth: A Call for Advocacy to Close the Gap

Disparate Access to Fertility Preservation in Youth: A Call for Advocacy to Close the Gap

Crosstalk between Noncoding RNAs and the Epigenetics Machinery in Pediatric Tumors and Their Microenvironment.

According to the World Health Organization, every year, an estimated 400,000+ new cancer cases affect children under the age of 20 worldwide. Unlike adult cancers, pediatric cancers develop very early in life due to alterations in signaling pathways that regulate embryonic development, and environmental factors do not contribute much to cancer development. The highly organized complex microenvironment controlled by synchronized gene expression patterns plays an essential role in the embryonic stages of development. Dysregulated development can lead to tumor initiation and growth. The low mutational burden in pediatric tumors suggests the predominant role of epigenetic changes in driving the cancer phenotype. However, one more upstream layer of regulation driven by ncRNAs regulates gene expression and signaling pathways involved in the development. Deregulation of ncRNAs can alter the epigenetic machinery of a cell, affecting the transcription and translation profiles of gene regulatory networks required for cellular proliferation and differentiation during embryonic development. Therefore, it is essential to understand the role of ncRNAs in pediatric tumor development to accelerate translational research to discover new treatments for childhood cancers. This review focuses on the role of ncRNA in regulating the epigenetics of pediatric tumors and their tumor microenvironment, the impact of their deregulation on driving pediatric tumor progress, and their potential as effective therapeutic targets.

Self-reported outcomes on oral health and oral health-related quality of life in long-term childhood cancer survivors—A DCCSS-LATER 2 Study

PurposeThe present study aimed to determine the prevalence of self-reported oral problems and the oral health–related quality of life (OHRQoL) in childhood cancer survivors (CCS).MethodsPatient and treatment characteristics of CCS have been collected in a cross-sectional study, part of the multidisciplinary DCCSS-LATER 2 Study. To assess self-reported oral health problems and dental problems, CCS filled out the ‘Toegepast-Natuurwetenschappelijk Onderzoek’ (TNO) oral health questionnaire. OHRQoL was assessed by the Dutch version of the Oral Health Impact Profile-14 (OHIP-14). Prevalences were compared with two comparison groups from the literature. Univariable and multivariable analyses were performed.ResultsA total of 249 CCS participated in our study. The OHIP-14 total score had a mean value of 1.94 (sd 4.39), with a median score of 0 (range 0–29). The oral problems ‘oral blisters/aphthae’ (25.9%) and ‘bad odor/halitosis’ (23.3%) were significantly more often reported in CCS than in comparison groups (12% and 12%, respectively). The OHIP-14 score was significantly correlated with the number of self-reported oral health problems (r = .333, p<0.0005) and dental problems (r = .392, p <0.0005). In multivariable analysis, CCS with a shorter time since diagnosis (10-19 years vs. ≥30 years) had a 1.47-fold higher risk of ≥1 oral health problem.ConclusionThough the perceived oral health is relatively good, oral complications following childhood cancer treatment are prevalent in CCS. This underlines that attention to impaired oral health and awareness on this topic is mandatory and regular visits to the dentist should be a part of long-term follow-up care.

Analysis of etiological factors of nursing diagnosis of impaired comfort in children and adolescents with cancer.

To analyse the etiological factors of the nursing diagnosis of impaired comfort in children and adolescents with cancer. This cross-sectional study was carried out in the referral unit for the treatment of childhood cancer in a tertiary hospital located in northeastern Brazil. A total of 200 children and adolescents who were undergoing cancer treatment were included in this study. Data collection instruments and protocols were constructed with operational and conceptual definitions of clinical indicators and etiological factors for the nursing diagnosis of impaired comfort. A latent class model with adjusted random effects was used to determine impaired comfort and measures of sensitivity and specificity of clinical indicators. A univariate logistic regression analysis was performed for each etiological factor of impaired comfort. The analysis of etiological factors for the nursing diagnosis of impaired comfort in children and adolescents with cancer showed the high prevalence of four factors: noxious environmental stimuli, insufficient situational control, insufficient resources and insufficient environmental control. Illness-related symptoms, noxious environmental stimuli, and insufficient environmental control increased the chance of impaired comfort occurring. The etiological factors with the highest prevalence and most significant impact on the occurrence of impaired comfort were noxious environmental stimuli, insufficient situational control and illness-related symptoms. The results obtained in this investigation can support more accurate nursing diagnostic inference of impaired comfort in children and adolescents with cancer. Moreover, the results can inform direct interventions for the modifiable factors that trigger this phenomenon to avoid or minimize the signs and symptoms of the nursing diagnosis.

Impact of COVID-19 containment measures on children with cancer in Indonesia

Containment measures to limit COVID-19 spreading profoundly impact children around the globe, especially in low- and middle-income countries such as Indonesia. The aim of this case series study is to uncover the impact that COVID-19 measures have on Indonesian children with cancer and their families. A case series study was conducted in July 2021. Investigators identified three children diagnosed with cancer at an Indonesian referral hospital and studied their medical records. Caretakers were interviewed inside the hospital by an independent interviewer using a semi-structured questionnaire. This study presents three children with cancer and their families. Access to proper healthcare was hindered during COVID-19 pandemic due to mobility restrictions, medical staff shortage, limited chemotherapy and blood products availability, postponed medical procedures, and delayed or modified treatment administration. Financial hardships resulted because caretakers lost their jobs due to lockdowns and medication costs were no longer fully covered by health-insurance. Children and their relatives suffered from mental health issues. Anxiety, depression, stress and loneliness were caused by the fear of receiving suboptimal cancer treatment, serious concerns about financial difficulties, and restricted social interactions. All families believed that COVID-19 measures worsened their children’s survival chances. COVID-19 measures adversely impact children with cancer and their families in Indonesia, and most likely in other low- and middle-income countries as well. Disruptions in timely and adequate childhood cancer treatment administration may importantly deteriorate survival chances. Governments and policymakers should take these indirect effects into account to protect vulnerable children and their families.

Radiation-induced sarcomas following childhood cancer - A Canadian Sarcoma Research and Clinical Collaboration Study (CanSaRCC).

Radiation-induced sarcoma (RIS) is a late toxicity of radiation therapy (RT) usually associated with poor prognosis. Due to ongoing improvements in childhood cancer treatment and patient outcomes, RIS may become more prevalent notwithstanding evolving indications for RT. Due to limited reported studies, we sought to review our experience with RIS in survivors of pediatric cancer. Data were collected on RIS patients following treatment for childhood cancer (initial diagnosis <18 years) identified in the CanSaRCC database. Additionally, details on the protocol guidance at time of treatment were compared with current guidelines for the same disease. Among 12 RIS identified, median age at initial diagnosis was 3.5 years (range 0.16-14) and the latency from RT to RIS diagnosis was 24.5 (range 5.4-46.2) years. Initial diagnoses included neuroblastoma, rhabdomyosarcoma, Ewing sarcoma, Wilms tumor, retinoblastoma and Hodgkin's Lymphoma. RIS histologies included osteosarcoma and soft tissue sarcomas. In comparison to protocols followed at time of diagnosis to current ones (2022), 7/12 (58%) patients would have required RT. RIS treatment included chemotherapy, radiation and surgery in 3/11 (27%), 10/11 (90%), and 7/11 (63%) patients, respectively. With a median follow-up time of 4.7 years from diagnosis of RIS, 8 (66%) patients were alive and 4 (33%) had died of progressive RIS. RIS is a serious late effect of radiotherapy in childhood cancer; however, radiation remains an integral component of primary tumor management and requires participation from a specialized multi-disciplinary team, aiming to mitigate RIS and other potential late effects.

Surgically Amenable Childhood Cancers: An Overview of the Burden and Challenges of Management in Low- and Middle-Income Countries.

The World Health Organization's Global Initiative for Childhood Cancer was launched to decrease the disparities in childhood cancer outcomes and improve treatments for childhood cancer in resource-limited settings. Low-grade glioma, retinoblastoma, and Wilms tumors are among the index cancers included in this global initiative, as these cancers represent a large percentage of childhood tumors and are curable with cost-effective, evidence-based interventions. Herein, we discuss the global childhood tumor burden, the status of pediatric cancer surgery capacity and services around the world, and the strategic considerations for building pediatric surgical oncology capacity.

Understanding the patient and family experience of nutrition and dietetic support during childhood cancer treatment

PurposeThis study aimed to understand the experience of families caring for a child with cancer in New Zealand (NZ) who received nutrition and dietetic support during cancer treatment and their preferences for the delivery, format, and timing of nutrition information.MethodsChildhood cancer patients and their families (N = 21) participated in a mixed-methods study at a specialist paediatric oncology centre in Auckland, NZ. Before the semi-structured interview, participants completed a questionnaire capturing demographic, disease, and treatment characteristics of their child, their nutrition concerns, and their information needs. Quantitative data were described, and qualitative thematic analysis of the semi-structured interviews was performed using NVivo data analysis software.ResultsEighty-six percent of participants indicated they had concerns about their child’s nutrition during treatment. The most common concerns were anorexia, vomiting, and weight loss. While many were happy with the quality of the nutrition support received, one-third of the patients wanted more support. Four key themes emerged from the interviews: (1) patients experience significant and distressing nutrition challenges; (2) patients and families have mixed perceptions of EN; (3) there are gaps in the current nutrition support system for inpatients; and (4) a desire for more accessible nutrition support.ConclusionChildhood cancer patients and families experience significant and distressing nutrition challenges during treatment. Standardising information given to patients and their families may optimise nutrition support for paediatric oncology patients and reduce the discordance between families and health professionals. Future implementation of a nutrition decision aid in this population is warranted.
