Severe fatigue after treatment for childhood cancer

The development of fatigue after treatment for pediatric brain tumors does not differ between tumor locations

BACKGROUND

Children and adolescents treated for a brain tumor suffer from more fatigue than survivors of other types of childhood cancer. As tumor location might be predictive of fatigue, our aim was to investigate the longitudinal development of fatigue in children with brain tumors and risk factors for fatigue separately for different tumor locations.

METHODS

Fatigue was assessed 1235 times for 425 participants. Self-report versions of PedsQL Multidimensional Fatigue Scale were used to repeatedly assess fatigue from the end of treatment up to 8 years later. Mixed models were used to analyze fatigue over time and determinants separately for infratentorial (N = 205), supratentorial hemispheric (N = 91), and supratentorial midline tumors (N = 129).

RESULTS

Cognitive fatigue worsened with time, while sleep-rest and general fatigue first decreased and then increased. There was no difference in fatigue between the tumor locations, but the risk factors differed when stratified by location. Radiotherapy was associated with more fatigue for infratentorial tumors, and centralization of care was associated with less fatigue for the supratentorial midline tumors. For supratentorial hemispheric tumors, female sex was associated with more fatigue. Higher parental education was associated with less fatigue regardless of tumor location.

CONCLUSIONS

The development of fatigue seems to be more related to sociodemographic and treatment variables than to tumor location. Healthcare providers need to be aware that fatigue may develop in the years following end of treatment, and that patients with a low/middle educational family background might be more vulnerable and in need of targeted support.

Effect of a 1-year physical activity intervention on quality of life, fatigue, and distress in adult childhood cancer survivors-A randomized controlled trial (SURfit)

INTRODUCTION

Childhood cancer survivors (CCS) are at risk of experiencing lower quality-of-life, fatigue, and depression. Few randomized controlled trials have studied the effect of physical activity (PA) on these in adult long-term CCS. This study investigated the effect of a 1-year individualized PA intervention on health-related quality-of-life (HRQOL), fatigue, and distress symptoms in adult CCS.

METHODS

The SURfit trial randomized 151 CCS ≥16 years old, <16 at diagnosis and ≥5 years since diagnosis, identified through the Swiss Childhood Cancer Registry. Intervention participants received personalized PA counselling to increase intense PA by ≥2.5 h/week for 1 year. Controls maintained usual PA levels. The authors assessed physical- and mental-HRQOL, fatigue, and distress symptoms at baseline, 3, 6, and 12 months. T-scores were calculated using representative normative populations (mean = 50, standard deviation = 10). Generalized linear mixed-effects models with intention-to-treat (ITT, primary), and three per-protocol allocations were used.

RESULTS

At 12 months, ITT (-3.56 larger decrease, 95% confidence interval -5.69 to -1.43, p = .001) and two per-protocol analyses found significantly lower fatigue. Physical-HRQOL improved significantly in two per-protocol analyses at 12 months. No other effects were found.

CONCLUSION

SURfit showed that increased intense PA over 1 year improved fatigue in adult CCS. Survivors should be recommended PA to reduce the burden of late-effects.

Fatigue in children who have recently completed treatment for acute lymphoblastic leukemia: a longitudinal study

BACKGROUND

This study examined fatigue in patients treated for childhood acute lymphoblastic leukemia (ALL) over a 2-year period (3- to 27-months post-treatment completion), from the perspective of children and parent caregivers, compared to a healthy comparison group.

METHODS

Eighty-three patients (4-16 years at enrolment) and their parents, reported on the child's fatigue using the Pediatric Quality of Life Inventory- Multidimensional Fatigue Scale (PedsQL-MFS), at 3- 15- and 27-months post-treatment completion, and 53 healthy children and their parents reported on fatigue across the same timepoints.

RESULTS

Parent proxy-reporting showed that parents of ALL patients reported more total fatigue than parents of the comparison group at all time points, with all subscales elevated (general, cognitive, and sleep/rest fatigue). In contrast, patient self-report of fatigue over this period differed from the comparison children for the general fatigue subscale only. Self-reported total fatigue was worse than the comparison group at the 27-month timepoint, with cognitive and sleep/rest fatigue symptoms contributing to this difference. Expected improvements in fatigue over time were not evident in either patient or parent report and no demographic risk factors were identified. Parents and children from both groups reported significantly more fatigue at all time points compared to commonly utilised normative population data.

CONCLUSIONS

Patients treated for childhood ALL are impacted by fatigue symptoms in the post-treatment and early survivorship period. These findings highlight that patients in the 2-years following treatment require increased symptom surveillance and may benefit particularly from interventions that target cognitive and sleep/rest fatigue.

Prevalence and factors associated with cancer-related fatigue in Swiss adult survivors of childhood cancer

PURPOSE

Reported prevalence of cancer-related fatigue (CRF) among childhood cancer survivors (CCS) varies widely, and evidence on factors associated with CRF among CCS is limited. We aimed to investigate the prevalence of CRF and its associated factors among adult CCS in Switzerland.

METHODS

In a prospective cohort study, we invited adult CCS who survived at least 5 years since last cancer diagnosis, and were diagnosed when age 0-20 years and treated at Inselspital Bern between 1976 and 2015 to complete two fatigue-measuring instruments: the Checklist Individual Strength subjective fatigue subscale (CIS8R; increased fatigue 27-34, severe fatigue ≥ 35) and the numerical rating scale (NRS; moderate fatigue 4-6, severe fatigue 7-10). We collected information about previous cancer treatment and medical history, and calculated β coefficients for the association between CIS8R/NRS fatigue scores and potential determinants using multivariable linear regression.

RESULTS

We included 158 CCS (participation rate: 30%) with a median age at study of 33 years (interquartile range 26-38). Based on CIS8R, 19% (N = 30) of CCS reported increased fatigue, yet none reported severe fatigue. CRF was associated with female sex, central nervous system (CNS) tumors, sleep disturbance, and endocrine disorders. Lower CRF levels were observed among CCS age 30-39 years compared to those younger.

CONCLUSIONS

A considerable proportion of adult CCS reported increased levels of CRF.

IMPLICATIONS FOR CANCER SURVIVORS

CCS who are female and < 30 years old, have a history of CNS tumor, report sleep disturbance, or have an endocrine disorder should be screened for CRF.

Effectiveness of exergaming in reducing cancer-related fatigue among children with acute lymphoblastic leukemia: a randomized controlled trial

BACKGROUND

Little is known about the effectiveness of the newly emerging technology of exergaming in reducing Cancer Related Fatigue (CRF).

OBJECTIVES

The study's primary aim was to examine the effectiveness of exergaming in reducing CRF; the secondary aims were to improve functional capacity/endurance and promote physical activity (PA) among children with acute lymphoblastic leukemia (ALL).

METHODS

In this Randomized Controlled Trial (RCT), 45 children aged 6-14 years were randomly assigned into group-I, n = 22, and group II, n = 23. Group-I played exergaming of moderate intensity for 60 min, twice a week for three weeks. Group II was given an instructional session regarding the benefits of PA with advice to practice PA for 60 min twice a week. CRF, functional capacity/endurance, and PA were measured using the pediatric quality of life multidimensional fatigue scale (Ped-QLMFS), six-minute walk test (6-MWT), and Godin-Shepard Leisure Time Physical Activity Questionnaire (QSLTPAQ) respectively. All measurements were taken thrice; in the first, third, and fifth weeks of intervention.

RESULTS

Group-I demonstrated a significant reduction of CRF, and a significant increase of functional capacity/endurance compared to group-II over the five weeks study period. The effect of time × intervention interaction was significant. Based on Cohen's guidelines, CRF and functional capacity/endurance had large effect sizes (η² = 0.41, p = .00) and (η² = 0.27, p = .00) respectively.

CONCLUSION

The protocol of exergaming used in this RCT effectively reduces CRF and promotes functional capacity/endurance and PA in children with ALL undergoing chemotherapy. It may provide an alternative treatment modality to decrease the healthcare load.Key messagesCancer-related fatigue (CRF) is described as physical exhaustion, sleep disturbance, emotional distress, and cognitive dysfunction.Exergaming reduces CRF and promotes functional capacity/endurance and physical activity in children with acute lymphoblastic leukemia undergoing chemotherapy.Exergaming may provide an alternative treatment modality to decrease the healthcare load.

Evaluation of Chemotherapy Induced Peripheral Neuropathy, Sarcopenia and Fatigue in Children with Acute Lymphoblastic Leukaemia and Lymphoma in Tertiary Care Hospital, Dakshina Kannada

Objectives

The study aims to assess the proportion and magnitude of chemotherapy-induced peripheral neuropathy (CIPN) and other common complications reported in children with acute lymphoblastic leukaemia (ALL)/ acute lymphoblastic lymphoma (LBL) undergoing chemotherapy.

Material and Methods

The study included children between 5 and 18 years old with ALL/LBL undergoing chemotherapy in Tertiary Care Hospitals, Mangalore. The study was conducted using various instruments, including paediatric-modified total neuropathy scale for CIPN, handheld dynamometer for muscle strength, bioimpedance analyser for muscle mass, timed up-and-go test for physical performance, and national comprehensive cancer network (NCCN) guidelines for scoring cancer-related fatigue at 3-time points. The collected data were analysed by IBM Statistical Package for the Social Sciences version 29 using Z-scores with standard deviation for distinct ALL/LBL types. In addition, the Paired t-test compared the baseline outcome to the 3rd and 6th time points.

Results

The study evaluated 25 children with ALL undergoing chemotherapy based on the UKALL 2003 protocol during their maintenance phase. The study found that 25 children experienced CIPN, with changes in sensory and pin sensibility scores at 3 and 6 months. The study found a significant change in handgrip strength, body mass index, and muscle mass at 3 months, with no significant change in physical performance over time. Fatigue scores increased from baseline to 3 months, with significant changes observed for the 7-12 years age group at 3 months but not for the 5-6 years age group at 6 months.

Conclusion

Children with ALL/LBL undergoing chemotherapy experience CIPN and other side effects such as sarcopenia and fatigue. The study highlights the potential benefits of physiotherapy interventions and supportive care strategies aimed at managing the adverse effects of chemotherapy in children with ALL/LBL.

Exploring core symptoms and interrelationships among symptoms in children with acute leukemia during chemotherapy: A network analysis

PURPOSE

Children with acute leukemia have suffered from a considerable symptom burden during chemotherapy. However, few studies have focused on exploring the mechanisms among symptoms in children with acute leukemia. Our study aims to explore core symptoms and describe the interrelationships among symptoms in children with acute leukemia during chemotherapy.

METHODS

From January 2021 to March 2023, 469 children with acute leukemia were recruited from 20 Chinese cities. The Memorial Symptom Assessment Scale 10-18 (MSAS 10-18) was used to evaluate the prevalence and severity of symptoms during chemotherapy. A network analysis was performed by the R software based on 31 symptoms. Centrality indices and density were used to explore core symptoms and describe interrelationships among symptoms in the network during chemotherapy.

RESULTS

Worrying and feeling irritable were the central symptoms across the three centrality indices, including strength, closeness, and betweenness. Lack of energy was the most prevalent symptom; however, it was less central than other symptoms. The density of the "induction and remission" network significantly differed from other cycles' counterparts (p < 0.001). Global strength was greater in the " ≥ 8 years group " network than the " < 8 years group " network (p = 0.023).

CONCLUSION

Network analysis provides a novel approach to identifying the core symptoms and understanding the interrelationships among symptoms. Our study indicates the need to assess emotional symptoms in children with acute leukemia during chemotherapy, especially during the induction and remission phases, as well as in older children. Future research is imperative to construct trajectories of dynamic symptom networks and centrality indices in longitudinal data to investigate the causal relationships among symptoms.

Effect of concurrent training on physical performance and quality of life in children with malignancy: A systematic review and meta-analysis

Objective

This study aims to evaluate the intervention effect of concurrent training on children with malignant tumors to provide evidence for prescribing exercise for children with malignant tumors.

Methods

Twelve databases were searched from inception to October 15, 2022. Two researchers independently screened the literature, evaluated the quality, extracted the data, and performed the meta-analysis using R.

Result

A total of nine randomized controlled trials involving 371 children were included in this study. The meta-analysis revealed that muscle strength was significantly greater in the exercise group compared to the usual care group [SMD = 0.26, 95% CI (0.04, 0.48), P = 0.023], with subgroup analysis showing no significant difference in upper limb [SMD = 0.13, 95% CI (−0.17, 0.43), P = 0.318] and a considerable difference in lower limb strength [SMD = 0.41, 95% CI (0.08, 0.74), P = 0.015]. Physical activity [SMD = 0.57, 95% CI (0.03, 1.1), P = 0.038], timed up and down stairs test [SMD = −1.22, 95% CI (−2.04, −0.4), P = 0.004], 6-min walking ability [SMD = 0.75, 95% CI (0.38, 1.11), P &lt; 0.01], quality of life [SMD = 0.28, 95% CI (0.02, 0.53), P = 0.033], and cancer-related fatigue [SMD = −0.53, 95% CI (−0.86, −0.19), P = 0.002] were significantly better than the usual care group. There were no significant differences in peak oxygen uptake [SMD = 0.13, 95% CI (−0.18, 0.44), P = 0.397], depression [SMD = 0.06, 95% CI (−0.38, 0.5), P = 0.791], and withdrawal rates [RR = 0.59, 95% CI (0.21, 1.63), P = 0.308] between the two groups.

Conclusion

Concurrent training could improve physical performance for children with malignancy but had no significant effect on mental health. Because the quality level of evidence is mostly very low, future high-quality randomized controlled trials are required to confirm these findings.

Fatigue trajectories during pediatric ALL therapy are associated with fatigue after treatment: a national longitudinal cohort study

OBJECTIVE

Fatigue is one of the most prevalent and distressing symptoms reported by survivors of childhood cancer. There is currently a lack of longitudinal studies on cancer-related fatigue, and especially on the relationship between the course of fatigue during treatment and fatigue at follow-up. The purpose of the current study was therefore to investigate if the course of fatigue during treatment, treatment intensity, serious adverse events, sex, or age at diagnosis are associated with cancer-related fatigue after treatment.

METHODS

Participants were 92 children and adolescents diagnosed with acute lymphoblastic leukemia (mean age at diagnosis was 6.26 years). Fatigue was measured with PedsQL multidimensional fatigue scale proxy reports 5 months after diagnosis, 12 months after diagnosis, 24 months after diagnosis, and at follow-up 12 months after end of treatment. The effect of patient and treatment characteristics on fatigue reported at follow-up was tested through logistic regression analyses.

RESULTS

The course of fatigue during treatment significantly predicted fatigue reported at follow-up for general fatigue (p = .038, OR = 9.20), sleep/rest fatigue (p = .011, OR = 15.48), and cognitive fatigue (p < .001, OR = 10.78). None of the other variables were associated with fatigue at follow-up for any of the subscales.

CONCLUSIONS

The findings demonstrate that fatigue reported during treatment can predict fatigue at follow-up. These results stress the need for longitudinal assessments. Healthcare professionals need to be aware that pediatric patients who are fatigued during treatment need to receive additional attention and timely interventions since cancer-related fatigue will not resolve by itself in the first year after end of treatment.

Interventions to improve neurocognitive late-effects in pediatric and adolescent CNS tumor patients and survivors - a systematic review

Introduction

Survival of children and adolescents diagnosed with central nervous system (CNS) tumors massively improved over the last decades due to better diagnostics, treatment, and supportive care. However, morbidity is still the highest of all cancer entities in this age group with neurocognitive late-effects being one of the most severe.

Aim

With this systematic review, we aim to summarize interventions designed to prevent or improve neurocognitive late-effects in CNS tumor patients.

Method

We searched PubMed on August 16^th 2022 and included publications studying interventions for neurocognitive late-effects in pediatric and adolescent patients and survivors diagnosed with a CNS tumor. We included any form of neurocognitive intervention during treatment or following treatment completion. We considered all types of studies except for expert opinions and case reports.

Results

The literature search resulted in 735 publications. We included 43 publications in the full text screening and 14 met our inclusion criteria. Of those, two assessed the impact of pharmacological interventions, three of exercise interventions, five of online cognitive training, and four assessed behavioral interventions. Different neuropsychological test batteries and imaging were used to measure the impact of the respective interventions. Most studies showed a positive impact of the interventions in single to several of the subtests used.

Conclusion

We found several intervention studies indicating improvement of neurocognitive problems in children and adolescent CNS tumor survivors. In this population exercise interventions or online cognitive training might mitigate or improve neurocognitive late-effects.

The gap between expectations and reality: A qualitative study of psychosocial challenges of young childhood cancer survivors from the PACCS study

OBJECTIVE

In this sub-study from the 'PACCS' study, we explored the psychosocial experiences of children and adolescents in everyday life post-cancer treatment and the possible factors that can moderate these experiences.

METHODS

This is a qualitative explorative study using semi-structured interviews with 43 childhood cancer survivors between the ages of nine and 18 from Norway and Denmark. We conducted a secondary thematic analysis using Malterud's systematic text condensation.

RESULTS

Two main themes were identified: 'The post-treatment gap between expectations and reality' comprised two subthemes: (1) lack of mastery and feeling different and (2) lack of understanding and acceptance. The second main theme, 'Managing the gap', comprised three subthemes: (1) information and knowledge, (2) adjustments and adaptions and (3) social support and openness. The findings reveal that the psychosocial challenges resulted from the remaining ability gap(s). Measures such as tailored information, school adjustments and social support were potential dynamic factors affecting the gap(s) positively or negatively. Psychosocial challenges post-treatment are experiences of lack of acceptance and understanding from others.

CONCLUSION

To safeguard a positive transition back to everyday life, health care providers should support the survivors' psychosocial care, including getting back to school and re-entering social interactions.

Effectiveness and Safety of the Traditional Chinese Medicine Treatment (HuoxueHuayu Therapy) for Malignant Tumors: A Systematic Review and Meta-Analysis

Background. A malignant tumor is one of the refractory diseases that threaten human life and health. HuoxueHuayu therapy (one of the Traditional Chinese Medicine therapies to promote blood circulation and remove blood stasis) is widely used as an antitumor supplementary method. However, its efficacy and safety are still controversial. Therefore, the objective of this study was to provide evidence-based evidence for HuoxueHuayu therapy in the treatment of malignant tumors and confirm its safety and effectiveness. Methods. A systematic search in 8 electronic databases targeted randomized clinical studies evaluating HuoxueHuayu therapy for response evaluation, tumor progression rate, quality of life (QoL), peripheral hemogram, performance status, immunologic function, tumor marker, and blood coagulation function in cancer patients, published from the establishment of the database to December 31, 2020. Risk ratio (RR) was used for counting data, mean difference (MD) or standardized mean difference (SMD) was used for measurement data, and 95% confidence interval (CI) was used as efficacy analysis statistics. Results. Our search identified 69 studies, evaluating 4402 patients in total. Randomized controlled trials (RCTs) evaluated gastric (n = 14), lung (n = 18), pancreatic (n = 2), colorectal (n = 10), liver (n = 14), breast (n = 2), ovarian (n = 2), gallbladder (n = 1), esophagus (n = 1), and combined (n = 14) cancers and hematological malignancies (n = 2). The duration of HuoxueHuayu therapy ranged from 3 to 48 weeks. Methodological bias was low in 64 studies and high in 5 studies. HuoxueHuayu therapy was associated with significant improvement in response evaluation (Response Evaluation Criteria in Solid Tumor (RECIST): RR: 1.44, 95% CI: 1.27 to 1.63, I2 = 0%, n = 33 studies; World Health Organization Criteria in Solid Tumors (WHOCIST): RR: 1.40, 95% CI: 1.23 to 1.59, I2 = 0%, n = 26 studies), recurrence rate (RR: 0.85, 95% CI: 0.72 to 0.99, I2 = 0%, n = 2 studies), quality of life, performance status (MD: 5.60, 95% CI: 5.04 to 6.15, $p<0.001$ ), immunologic function (CD3: SMD: 1.23, 95% CI: 0.79 to 1.66, $p<0.001$ ; CD4: SMD: 1.25, 95% CI: 0.77 to 1.74, $p<0.001$ ; CD4/CD8: SMD: 1.05, 95% CI: 0.69 to 1.42, $p<0.001$ ; natural killer cell (NK): SMD: 0.74, 95% CI: 0.32 to 1.15, $p<0.001$ ), tumor marker, and blood coagulation function (D-dimer (D-D); fibrinogen (FIB)). In addition, HuoxueHuayu therapy could reduce toxicity caused by chemotherapy and radiotherapy without risks of liver and kidney injury or bleeding, although the effect on tumor metastasis was uncertain. Conclusions. The present update of our systematic review and meta-analyses provided essential evidence for the beneficial effect of HuoxueHuayu therapy to show promise in cancer treatment, improving quality of life, addressing cancer-related symptoms, and reducing toxicity in a secure way.

Insomnia Symptoms and Daytime Fatigue Co-Occurrence in Adolescent and Young Adult Childhood Cancer Patients in Follow-Up after Treatment: Prevalence and Associated Risk Factors

Insomnia symptoms and daytime fatigue commonly occur in pediatric oncology, which significantly impact physical and psychosocial health. This study evaluated the prevalence of insomnia only, daytime fatigue only, the co-occurrence of insomnia−daytime fatigue symptoms, and associated risk factors. Childhood cancer patients (n = 565, 12−26 years old, ≥6 months after treatment) participated in a national, cross-sectional questionnaire study, measuring insomnia symptoms (ISI; Insomnia Severity Index) and daytime fatigue (single item). Prevalence rates of insomnia and/or daytime fatigue subgroups and ISI severity ranges were calculated. Multinomial regression models were applied to assess risk factors. Most patients reported no insomnia symptoms or daytime fatigue (61.8%). In the 38.2% of patients who had symptoms, 48.1% reported insomnia and daytime fatigue, 34.7% insomnia only, and 17.1% daytime fatigue only. Insomnia scores were higher in patients with insomnia−daytime fatigue compared to insomnia only (p < 0.001). Risk factors that emerged were: female sex and co-morbidities (all), shorter time after treatment and bedtime gaming (insomnia only), young adulthood (insomnia−fatigue/fatigue only), needing someone else to fall asleep and inconsistent wake times (both insomnia groups), lower educational level and consistent bedtimes (insomnia−fatigue). Insomnia symptoms and daytime fatigue are common and often co-occur. While current fatigue guidelines do not include insomnia symptoms, healthcare providers should inquire about insomnia as this potentially provides additional options for treatment and prevention.

The Impact of Cancer-Related Fatigue on HRQOL in Survivors of Childhood Cancer: A DCCSS LATER Study

Simple Summary

Survivors of childhood cancer have an increased risk to experience symptoms of severe and persistent fatigue. We studied how fatigue might affect the health-related quality of life of these survivors. Questionnaire items asking about a broad range of daily life aspects were compared between fatigued survivors, survivors without fatigue and the general Dutch population. A total of eleven aspects were studied which were all negatively affected by fatigue, with the largest impact seen for Vitality (how much energy does a person have), General Health (perception of current and future health) and Role Limitations (work-related activities). Results show the negative impact fatigue can have on the daily lives of survivors and why it is important to treat fatigue adequately.

Abstract

Background: Early detection and management of late effects of treatment and their impact on health-related quality of life (HRQOL) has become a key goal of childhood cancer survivorship care. One of the most prevalent late effects is chronic fatigue (CF). The current study aimed to investigate the association between CF and HRQOL in a nationwide cohort of CCS. Methods: Participants were included from the Dutch Childhood Cancer Survivor Study (DCCSS) LATER cohort, a nationwide cohort of CCS. Participants completed the Checklist Individual Strength (CIS) to indicate CF (CIS fatigue severity subscale ≥ 35 and duration of symptoms ≥6 months) and the Short Form-36 (SF-36) and TNO (Netherlands Organization for Applied Scientific Research) and AZL (Leiden University Medical Centre) Adult’s Health-Related Quality of Life questionnaire (TAAQOL) as measures for HRQOL. Differences in mean HRQOL domain scores between CF and non-CF participants were investigated using independent samples t-tests and ANCOVA to adjust for age and sex. The association between CF and impaired HRQOL (scoring ≥ 2 SD below the population norm) was investigated using logistic regression analyses, adjusting for confounders. Results: A total of 1695 participants were included in the study. Mean HRQOL domain scores were significantly lower in participants with CF. In addition, CF was associated with impaired HRQOL on all of the domains (except physical functioning) with adjusted odds ratios ranging from 2.1 (95% CI 1.3–3.4; sexuality domain) to 30.4 (95% CI 16.4–56.2; vitality domain). Conclusions: CF is associated with impaired HRQOL, urging for the screening and regular monitoring of fatigue, and developing possible preventative programs and interventions.

Sarcopenia in Children with Solid Organ Tumors: An Instrumental Era

Sarcopenia has recently been studied in both adults and children and was found to be a prognostic marker for adverse outcome in a variety of patient groups. Our research showed that sarcopenia is a relevant marker in predicting outcome in children with solid organ tumors, such as hepatoblastoma and neuroblastoma. This was especially true in very ill, high-risk groups. Children with cancer have a higher likelihood of ongoing loss of skeletal muscle mass due to a mismatch in energy intake and expenditure. Additionally, the effects of cancer therapy, hormonal alterations, chronic inflammation, multi-organ dysfunction, and a hypermetabolic state all contribute to a loss of skeletal muscle mass. Sarcopenia seems to be able to pinpoint this waste to a high degree in a new and objective way, making it an additional tool in predicting and improving outcome in children. This article focuses on the current state of sarcopenia in children with solid organ tumors. It details the pathophysiological mechanisms behind sarcopenia, highlighting the technical features of the available methods for measuring muscle mass, strength, and function, including artificial intelligence (AI)-based techniques. It also reviews the latest research on sarcopenia in children, focusing on children with solid organ tumors.

Systematic Review: Sleep Disorders Based on Objective Data in Children and Adolescents Treated for a Brain Tumor

Background

Tumors of the central nervous system (CNS) are the most common solid childhood malignancy. Over the last decades, treatment developments have strongly contributed to the improved overall 5-year survival rate, which is now approaching 75%. However, children now face significant long-term morbidity with late-effects including sleep disorders that may have detrimental impact on everyday functioning and quality of life. The aims of this study were to (1) describe the symptoms that lead to polysomnographic evaluation; (2) describe the nature of sleep disorders diagnosed in survivors of childhood CNS tumor using polysomnography (PSG); and (3) explore the association between tumor location and diagnosed sleep disorder.

Methods

An extensive literature search following the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines (PRISMA) was conducted. Inclusion criteria were children and adolescents diagnosed with a CNS tumor age <20 years having a PSG performed after end of tumor treatment. The primary outcome was sleep disorder confirmed by PSG.

Results

Of the 1,658 studies identified, 11 met the inclusion criteria. All the included articles were appraised for quality and included in the analysis. Analyses indicated that sleep disorders commonly occur among childhood CNS tumor survivors. Symptoms prior to referral for PSG were excessive daytime sleepiness (EDS), fatigue, irregular breathing during sleep and snoring. The most common sleep disorders diagnosed were sleep-related breathing disorders (i.e., obstructive sleep apnea) and central disorders of hypersomnolence (i.e., narcolepsy).

Conclusion

Our findings point to the potential benefit of systematically registering sleep disorder symptoms among CNS tumor patients together with tumor type and treatment information, so that at-risk patients can be identified early. Moreover, future rigorous and larger scale controlled observational studies that include possible modifiable confounders of sleep disorders such as fatigue and obesity are warranted.

Natural Language Processing and Machine Learning Methods to Characterize Unstructured Patient-Reported Outcomes: Validation Study

BACKGROUND

Assessing patient-reported outcomes (PROs) through interviews or conversations during clinical encounters provides insightful information about survivorship.

OBJECTIVE

This study aims to test the validity of natural language processing (NLP) and machine learning (ML) algorithms in identifying different attributes of pain interference and fatigue symptoms experienced by child and adolescent survivors of cancer versus the judgment by PRO content experts as the gold standard to validate NLP/ML algorithms.

METHODS

This cross-sectional study focused on child and adolescent survivors of cancer, aged 8 to 17 years, and caregivers, from whom 391 meaning units in the pain interference domain and 423 in the fatigue domain were generated for analyses. Data were collected from the After Completion of Therapy Clinic at St. Jude Children's Research Hospital. Experienced pain interference and fatigue symptoms were reported through in-depth interviews. After verbatim transcription, analyzable sentences (ie, meaning units) were semantically labeled by 2 content experts for each attribute (physical, cognitive, social, or unclassified). Two NLP/ML methods were used to extract and validate the semantic features: bidirectional encoder representations from transformers (BERT) and Word2vec plus one of the ML methods, the support vector machine or extreme gradient boosting. Receiver operating characteristic and precision-recall curves were used to evaluate the accuracy and validity of the NLP/ML methods.

RESULTS

Compared with Word2vec/support vector machine and Word2vec/extreme gradient boosting, BERT demonstrated higher accuracy in both symptom domains, with 0.931 (95% CI 0.905-0.957) and 0.916 (95% CI 0.887-0.941) for problems with cognitive and social attributes on pain interference, respectively, and 0.929 (95% CI 0.903-0.953) and 0.917 (95% CI 0.891-0.943) for problems with cognitive and social attributes on fatigue, respectively. In addition, BERT yielded superior areas under the receiver operating characteristic curve for cognitive attributes on pain interference and fatigue domains (0.923, 95% CI 0.879-0.997; 0.948, 95% CI 0.922-0.979) and superior areas under the precision-recall curve for cognitive attributes on pain interference and fatigue domains (0.818, 95% CI 0.735-0.917; 0.855, 95% CI 0.791-0.930).

CONCLUSIONS

The BERT method performed better than the other methods. As an alternative to using standard PRO surveys, collecting unstructured PROs via interviews or conversations during clinical encounters and applying NLP/ML methods can facilitate PRO assessment in child and adolescent cancer survivors.

Using ICF to Describe Problems With Functioning in Everyday Life for Children Who Completed Treatment for Brain Tumor: An Analysis Based on Professionals' Documentation

Background: Children treated for brain tumors often experience persistent problems affecting their activity performance and participation in everyday life, especially in school. Linking these problems to the International Classification of Functioning, Disability and Health (ICF) classification system can be described as affecting body function, activity performance, and/or participation. Services involved in the everyday life of the child have different focus and goals when meeting the child in context, which advantage the use of ICF to overcome this impediment to follow-up and provide comprehensive support for children who have completed treatment for a brain tumor.

Aim: The aim of the study was to use the ICF classification system to describe how professionals in healthcare, habilitation, and school document problems with everyday life functioning at body, activity, and participation levels for children who completed treatment for a brain tumor.

Materials and Methods: A retrospective review of records from healthcare, habilitation, and school concerning nine children completed treatment for brain tumor was implemented. Identified problems in everyday life were linked to ICF codes. Descriptive statistics of ICF-linked code frequency supplemented by network visualization diagrams viewing the co-occurrence between codes within the body, activity participation, and environmental components were performed.

Results: Most documented problems were found in healthcare records, whereas the documentation in habilitation and school was sparse. The frequently occurring codes, independent of record source, were linked to the body function component, and ICF-linked problems in habilitation and school were salient in the activity and participation component. To gain a holistic picture of relations between ICF codes and problems, network visualization diagrams were used to illustrate clusters of problems.

Conclusion: Code prevalence likely reflects where healthcare professionals and educators focus their attention when meeting the needs of children treated for a brain tumor in context. To maximize the comprehensive view of functioning and participation of children in everyday life, the full range of difficulties regarding body impairments, activity limitations, and participation restrictions must be identified and linked to each other in patterns of co-occurrence, which the ICF facilitate. However, ICF provides no guidance on how to identify networks of problems within the body, activity, and participation. Identifying such networks is important for building comprehensive interventions for children.

"I have to do things differently now, but I make it work"-young childhood cancer survivors' experiences of self-management in everyday living

PURPOSE

Living with late effects can affect young childhood cancer survivors' (CCSs) self-management (SM) abilities. In this study, we explored different approaches to SM of everyday life by young CCS.

METHODS

This is a sub-study of a larger study on Physical Activity among Childhood Cancer Survivors (the PACCS study). We conducted individual interviews with 22 CCS aged 9 to 18 years who were at least 1 year off-treatment. An hybrid inductive-decductive thematic analysis was used.

RESULTS

Three main themes were identified: (1) managing everyday life with fatigue, (2) building self-management competence, and (3) cancer survivor as part of identity. Late effects, especially fatigue, contributed to a perceived ability gap compared to peers, limiting participation in everyday activities. CCS developed new SM skills to overcome such challenges and pushed themselves physically and mentally to master and balance activities and rest to regain energy. CCS changed activities, adapted their expectations, or legitimized their apparent lack of SM skills to regain a sense of self-efficacy. Managing the impact of cancer on relationships with family and friends also required use of SM strategies.

CONCLUSIONS

The findings expand our currently limited knowledge of young CCS and SM skills they develop to manage everyday life after treatment completion. These, combined with ongoing support from family and peers, "make it work".

IMPLICATIONS FOR CANCER SURVIVORS

The perspectives of young CCS illustrate their SM skills and support needs beyond transitioning off-treatment. Conceptualizing this within follow-up care may contribute to a feeling of mastery and increased satisfaction among CCS.

Methodology of the DCCSS later fatigue study: a model to investigate chronic fatigue in long-term survivors of childhood cancer

BACKGROUND

A debilitating late effect for childhood cancer survivors (CCS) is cancer-related fatigue (CRF). Little is known about the prevalence and risk factors of fatigue in this population. Here we describe the methodology of the Dutch Childhood Cancer Survivor Late Effect Study on fatigue (DCCSS LATER fatigue study). The aim of the DCCSS LATER fatigue study is to examine the prevalence of and factors associated with CRF, proposing a model which discerns predisposing, triggering, maintaining and moderating factors. Triggering factors are related to the cancer diagnosis and treatment during childhood and are thought to trigger fatigue symptoms. Maintaining factors are daily life- and psychosocial factors which may perpetuate fatigue once triggered. Moderating factors might influence the way fatigue symptoms express in individuals. Predisposing factors already existed before the diagnosis, such as genetic factors, and are thought to increase the vulnerability to develop fatigue. Methodology of the participant inclusion, data collection and planned analyses of the DCCSS LATER fatigue study are presented.

RESULTS

Data of 1955 CCS and 455 siblings was collected. Analysis of the data is planned and we aim to start reporting the first results in 2022.

CONCLUSION

The DCCSS LATER fatigue study will provide information on the epidemiology of CRF and investigate the role of a broad range of associated factors in CCS. Insight in associated factors for fatigue in survivors experiencing severe and persistent fatigue may help identify individuals at risk for developing CRF and may aid in the development of interventions.

A vulnerable age group: the impact of cancer on the psychosocial well-being of young adult childhood cancer survivors

Purpose

This study aimed to increase our understanding of the psychosocial well-being of young adult childhood cancer survivors (YACCS) as well as the positive and negative impacts of cancer.

Methods

YACCS (aged 18–30, diagnosed ≤ 18, time since diagnosis ≥ 5 years) cross-sectionally filled out the “Pediatric Quality of Life Inventory Young Adults” (PedsQL-YA), “Hospital Anxiety and Depression Scale” (HADS), and “Checklist Individual Strengths” (CIS-20R) to measure fatigue and survivor-specific “Impact of Cancer - Childhood Survivors” (IOC-CS), which measures the long-term impact of childhood cancer in several domains. Descriptive statistics (IOC-CS), logistic regression (HADS, CIS-20R), and ANOVA (PedsQL-YA, HADS, CIS-20R) were performed. Associations between positive and negative impacts of childhood cancer and psychosocial outcomes were examined with linear regression analyses.

Results

YACCS (N = 151, 61.6% female, mean age 24.1 ± 3.6, mean time since diagnosis 13.6 ± 3.8) reported lower HRQOL (− .4 ≤ d ≤ − .5, p ≤ .001) and more anxiety (d = .4, p ≤ .001), depression (d = .4, p ≤ .01), and fatigue (.3 ≤ d ≤ .5, p ≤ .001) than young adults from the general Dutch population. They were at an increased risk of experiencing (sub)clinical anxiety (OR = 1.8, p = .017). YACCS reported more impact on scales representing a positive rather than negative impact of CC. Various domains of impact of childhood cancer were related to psychosocial outcomes, especially “Life Challenges” (HRQOL β = − .18, anxiety β = .36, depression β = .29) and “Body & Health” (HRQOL β = .27, anxiety β = − .25, depression β = − .26, fatigue β = − .47).

Conclusion

YACCS are vulnerable to psychosocial difficulties, but they also experience positive long-term impacts of childhood cancer. Positive and negative impacts of childhood cancer were associated with psychosocial outcomes in YACCS. Screening of psychosocial outcomes and offering targeted interventions are necessary to optimize psychosocial long-term follow-up care for YACCS.

Role of parents in fatigue of children with a chronic disease: a cross-sectional study

OBJECTIVE

As parents majorly impact their child's well-being, and as fatigue is a highly prevalent threat to the well-being of children with a chronic disease, we aimed to explore the association between parental factors and fatigue in children with a chronic disease.

DESIGN

Cross-sectional study.

SETTING

Two Dutch children's hospitals.

POPULATION

Children 2-18 years of age with either an autoimmune disease, cystic fibrosis or post-cancer treatment, and one of their parents.

MAIN OUTCOME MEASURES

Paediatric fatigue was measured using the PedsQL Multidimensional Fatigue Scale. Parental factors included parental pain, fatigue and physical symptoms, parental distress, catastrophising thoughts about their child's pain and family empowerment. Multiple linear regressions were used to study associations with paediatric fatigue. A multivariable regression model was used to assess the effect of the different parental factors on paediatric fatigue. All analyses were adjusted for the age and sex of the child.

RESULTS

204 families participated (mean age 11.0±4.3 and 43.5±6.3 years for children and parents, respectively; 69% participation rate). More parental pain, fatigue and physical symptoms, and more parental distress and pain catastrophising were associated with more paediatric fatigue. More parental empowerment was associated with less paediatric fatigue on both subscales. In the multivariable model, only paediatric age remained significantly associated with fatigue. In a separate multivariable model for children 8-18 years old, more parental distress (β=-1.9, 95% CI -3.7 to -0.1) was also significantly associated with more paediatric fatigue.

CONCLUSIONS

In a population of children with a chronic disease, parental factors, both physical and psychosocial, were associated with paediatric fatigue. Our study provides evidence that more family empowerment is associated with less paediatric fatigue. This exploratory study adds to our knowledge of associated factors with fatigue in paediatric chronic disease, providing starting points for targeted interventions.

A Review of Acute and Long-Term Neurological Complications Following Haematopoietic Stem Cell Transplant for Paediatric Acute Lymphoblastic Leukaemia

Despite advances in haematopoietic stem cell transplant (HSCT) techniques, the risk of serious side effects and complications still exists. Neurological complications, both acute and long term, are common following HSCT and contribute to significant morbidity and mortality. The aetiology of neurotoxicity includes infections and a wide variety of non-infectious causes such as drug toxicities, metabolic abnormalities, irradiation, vascular and immunologic events and the leukaemia itself. The majority of the literature on this subject is focussed on adults. The impact of the combination of neurotoxic drugs given before and during HSCT, radiotherapy and neurological complications on the developing and vulnerable paediatric and adolescent brain remains unclear. Moreover, the age-related sensitivity of the nervous system to toxic insults is still being investigated. In this article, we review current evidence regarding neurotoxicity following HSCT for acute lymphoblastic leukaemia in childhood. We focus on acute and long-term impacts. Understanding the aetiology and long-term sequelae of neurological complications in children is particularly important in the current era of immunotherapy for acute lymphoblastic leukaemia (such as chimeric antigen receptor T cells and bi-specific T-cell engager antibodies), which have well-known and common neurological side effects and may represent a future treatment modality for at least a fraction of HSCT-recipients.

Positive Impact of Organized Physical Exercise on Quality of Life and Fatigue in Children and Adolescents With Cancer

Background: Cancer and its treatment can cause serious health issues that impair physical and mental well-being in children and adolescents. Exercise may be a valid strategy for managing some symptoms, including fatigue. In the light of our experience, we provide further justification for including exercise as part of routine childhood cancer care. Methods: Forty-four children and adolescents who had solid cancers not contraindicating their movement were invited to join an in-hospital 6-week supervised exercise program, and asked afterwards to complete validated quality of life and fatigue scales. The program consisted of personalized workout sessions of aerobic, resistance and flexibility exercises. The results obtained on the scales were compared between 21 patients who engaged in the exercise program (GYM group) and 23 who refused (No-GYM group), examining the different dimensions of health-related quality of life (physical, emotional, cognitive, social) and fatigue (general, sleep/rest, cognitive) in the two groups. Results: Being diagnosed with cancer initially prompted all but one of the respondents to drop-out of previous routine exercise or sports although their continuation had not been contraindicated. After 6 weeks of exercise, the GYM group's scores for quality of life and fatigue showed a statistically significant better perceived emotional functioning, and a trend toward a better social functioning than in the No-GYM group. Conclusion: We suggest that exercise improves the satisfaction of children and adolescents with cancer with their physical, mental and social functioning. We would emphasize the potential benefits of general practitioners discussing and recommending exercise for their young patients with cancer.

Lifetime Costs of Surviving Cancer-A Queensland Study (COS-Q): Protocol of a Large Healthcare Data Linkage Study

Australia-wide, there are currently more than one million cancer survivors. There are over 32 million world-wide. A trend of increasing cancer incidence, medical innovations and extended survival places growing pressure on healthcare systems to manage the ongoing and late effects of cancer treatment. There are no published studies of the long-term health service use and cost of cancer survivorship on a population basis in Australia. All residents of the state of Queensland, Australia, diagnosed with a first primary malignancy from 1997–2015 formed the cohort of interest. State and national healthcare databases are linked with cancer registry records to capture all health service utilization and healthcare costs for 20 years (or death, if this occurs first), starting from the date of cancer diagnosis, including hospital admissions, emergency presentations, healthcare costing data, Medicare services and pharmaceuticals. Data analyses include regression and economic modeling. We capture the whole journey of health service contact and estimate long-term costs of all cancer patients diagnosed and treated in Queensland by linking routinely collected state and national healthcare data. Our results may improve the understanding of lifetime health effects faced by cancer survivors and estimate related healthcare costs. Research outcomes may inform policy and facilitate future planning for the allocation of healthcare resources according to the burden of disease.
