Effects of a 6-Month, Group-Based, Therapeutic Exercise Program for Childhood Cancer Outpatients on Motor Performance, Level of Activity, and Quality of Life

Implementing a behavioral physical activity program in children and adolescent survivors of childhood cancer: a pilot randomized controlled trial

Purpose We aimed to document the acceptability (enrollment rate) and feasibility (phone call delivery rate) of implementing a behavioral PA intervention over 12 weeks, in addition to documenting its effects on patient-reported outcomes and physical functioning. This study also describes the costs of carrying out a behavioral PA intervention. A total of 40 participants were randomized in a 1:1 ratio. The tailored behavioral PA intervention was developed based on the most recent PA guidelines in pediatric oncology and on the COM-B framework to enact PA behavior changes. The prescription (frequency, intensity, time and type (FITT)) was adjusted each week during the weekly support calls. The control group did not receive the intervention. 26 males and 14 females (13.6 years old on average and 2.9 years post-cancer treatment on average) participated in our study. The acceptability rate was 90.9% and the feasibility rate was > 85%. We found that 85% improved PA frequency, 80% improved PA intensity, 100% improved PA time, and 50.0% achieved the recommended PA guidelines. No adverse events were reported over the duration of the intervention. Physical function improved with longer 6-minute walk distances in the intervention group (465.8 ± 74.5 m) than in the control group (398.7 ± 92.9 m) (p = 0.016). PROs scores for all participants were within the limits of the normal range. The estimated cost per participant of carrying out this intervention was USD $126.57. Our 12-week behavioral PA intervention, based on the COM-B framework, was found to be acceptable, feasible and safe in childhood cancer survivors. This study is an important step in the right direction to make exercise standard practice in pediatric oncology.

Effects of Group Exercise Intervention on Quality of Life and Physical Parameters in Patients with Childhood Cancer: A Systematic Review

BACKGROUND

Although the survival rates of childhood cancer are increasing, children diagnosed as having cancer experience psychological and physical problems and a declining quality of life (QOL).

METHODS

A systematic review of PubMed databases was conducted up to September 2023 to identify studies reporting the effects of group exercise intervention in children with cancer. The inclusion criteria were pre-specified, including children aged ≤19 years old who received group exercise intervention and interventional studies written in English. Studies involving non-exercise intervention or non-group intervention were excluded.

RESULTS

Five studies were included in the present review. In three studies, QOL and physical parameters were improved after group exercise intervention, and in two studies, only physical parameters were improved. Improvements in QOL were achieved through psychosocial variables, improved scores of subscales of pain and hurt, nausea, and procedure-related anxiety, and reduced cancer-related fatigue. All studies had high numbers of participants who completed the intervention. However, all studies showed a high risk of bias regarding the selection of the reported results, and most studies showed a high risk of bias regarding deviations from the intended intervention and outcome measurement.

CONCLUSION

The reviewed studies showed that group exercise intervention for children with cancer could improve their QOL and/or physical parameters.

Effects of Exercise and Physical Activity Levels on Childhood Cancer: An Umbrella Review

Patients and survivors of childhood cancer experience adverse effects related to the disease and its treatment. These adverse effects are associated with both physiological and psychological health. Exercise helps manage the side effects and improve the health outcomes. The objective of this umbrella review is to search the current literature in the context of exercise and physical activity as complementary interventions on pediatric cancer and to provide comprehensive information about the derived health outcomes. A literature search was conducted on the Cochrane, PubMed, and Embase databases for systematic reviews published up to January 2023. Moreover, a hand search of reference lists was performed. We included participants under 19 years of age at diagnosis of any type of childhood cancer, without restriction on the type or phase of treatment, who participated in exercise interventions. The results showed a beneficial impact on fatigue, muscle strength, aerobic capacity, activity and participation levels, psychosocial health, cardiovascular/cardiorespiratory fitness, physical function, bone mineral density, and brain volume and structure, with limited and not serious adverse effects. These findings documented that exercise interventions had a positive effect on many physiological and psychological health outcomes in pediatric cancer patients and survivors.

Exercise Preferences in Young Adults with Cancer-The YOUEX Study

(1) Background: Strong evidence supports the persuasive positive effects of exercise for cancer patients and survivors. Different approaches of exercise programs have been established; however, the special interests of young adults (YAs) with cancer have rarely been considered in exercise interventions. Therefore, the study YOUng EXercisers (YOUEX) aimed to investigate exercise preferences in YAs. (2) Methods: YOUEX was a three-arm, patient preference-based non-randomized, longitudinal, pre-post exercise intervention, offering three different exercise modules to YAs during or after acute therapy (Module 1: online supervised group-based (M1); Module 2: online unsupervised (M2); Module 3: in-person supervised (M3)). The intervention period was 12 weeks with another 12-week follow-up period, the modules could be changed or amended after 6 and 12 weeks. (3) Results: 92 YAs were allocated to the study. At baseline, 50 YAs (54%) chose M2, 32 YAs (35%) M1 and 10 YAs (11%) M3. The analysis revealed high acceptability and feasibility of the online exercise programs (M1, M2). There was a high impact of the COVID-19 pandemic on the execution of M3. YAs showed diverse preferences in module selection due to differences in, e.g., cancer therapy status or favored level of supervision. (4) Conclusions: YAs need personalized exercise programs that consider their individual interests and needs. Online exercise programs can be a promising addition to existing exercise opportunities. They are an effective way to increase physical activity levels in YAs.

Health utility of children with acute lymphoblastic leukemia in China

Background

Acute lymphoblastic leukemia is the most common cancer in children. As the 5-year survival rate has been improved to over 80%, more emphasis is now placed on reducing therapy toxicities and enhancing health-related quality of life (HRQoL) of patients during treatment. Our objective was to measure health utility of pediatric acute lymphoblastic leukemia (pALL) patients in China, examine utility weights of different treatment phases and influencing factors of health utility, as well as identify which aspects of HRQoL were most impaired.

Methods

A cross-sectional study was conducted in Shanghai Children's Medical Center (SCMC) Affiliated to Shanghai Jiao Tong University School of Medicine in China from April to November 2021. Primary caregivers of 247 patients completed the assessment by CHU9D-CHN and health utility scores were computed for all the patients and stratified by treatment phases. Various multivariable models were constructed and the best was chosen to identify independent factors associated with utility scores. Factors affecting the most impaired dimensions were also examined.

Results

The overall mean (SD) health utility score was 0.79 (±0.17) and significantly increased from induction (0.73 [±0.19], P < 0.001) to consolidation (0.74 [±0.18]), and to maintenance (0.82 [±0.16]). After adjusting for potentially influencing factors, utility scores in induction (Beta = -0.086, P = 0.005) and consolidation (Beta = -0.074, P = 0.043) were constantly lower than those during maintenance. In item-level analysis, lower age and induction phase were found to be significantly associated with high severity reported on the "school work/homework" dimension. Additionally, only the induction phase (vs. maintenance, OR = 2.24, P = 0.016) was independently associated with the high severity level reported on the "able to join in activities" dimension.

Conclusions

This is the first study that measured health utility of children with pALL in China. Mean health utility scores increased from induction to maintenance. These provided important utility estimates that help inform future health economic models. The phrasing of "School work/homework" in CHU9D-CHN could be further improved. More efforts are needed to design and implement specific interventions targeting at the dimension "able to join in activities" for enhancing HRQoL of children with pALL in China.

Design and Evaluation of an Outdoor Exercise Program for Pediatric Cancer Survivors

Exercise programs for young people after cancer are not part of regular oncological care. This study describes and evaluates a regional outdoor exercise program and presents data with regard to the promoting and inhibiting factors for participation among pediatric cancer survivors. Exercise options, number of participants, and the cohort were evaluated descriptively for one year. A self-developed questionnaire was used to evaluate satisfaction, mood, motivations, and barriers to exercise. Overall N = 26 survivors (14.6 ± 5.5 years) participated in at least one activity in 2019 including try-out days (N = 10) and active weekend camps (N = 2). No adverse events occurred in 302 physical activity hours. Twenty-one survivors participated in the survey. The largest motivational aspect to participate was “to try out a new sport” (83.9%). Survivors reported “good mood”, and ‘being happy’ after exercising. The largest barrier was concern about ‘not being able to keep up with others’ (38.1%). Around one-third (try-out day) and 50% (active weekend camp) of survivors did not feel confident to continue exercising outside the supervised exercise oncology program. This survey shows high enthusiasm for this exercise program with different outdoor activities and suggests that similar interventions may be accepted by this population.

Feasibility and benefits of a videoconferencing-based home exercise programme for paediatric cancer survivors during the coronavirus disease 2019 pandemic

Objective

We aimed to determine the feasibility and benefits of a videoconferencing‐based home exercise programme to improve health‐related quality of life (HRQOL), posttraumatic growth and physical strength levels of paediatric cancer survivors during the coronavirus disease 2019 (COVID‐19).

Methods

Eight paediatric cancer survivors participated in the intervention for 8 weeks. The programme comprised home exercise sessions administered using Zoom, a videoconferencing platform. The supervised exercise sessions were performed two times per week; the participants were taught to perform joint exercises at home for the remaining 5 days of the week. HRQOL, posttraumatic growth and physical strength levels were assessed at baseline and after the intervention.

Results

The rates of recruitment, retention and attendance were 52.9%, 88.9% and 98.4%, respectively. There were no cases of adverse events. The programme significantly improved flexibility (z = −2.21, p = 0.03), muscle strength (z = −2.67, p = 0.01) and power (z = −2.41, p = 0.02) among five domains of physical fitness measured using a physical activity promotion system and also improved total physical strength (z = −2.67, p = 0.01). Posttraumatic growth decreased slightly, whereas HRQOL improved slightly; however, the change was not statistically significant.

Conclusion

The study findings present preliminary evidence of the feasibility and benefits of this videoconferencing‐based home exercise programme among paediatric cancer survivors.

Whole-body vibration training for inpatient children and adolescents receiving chemotherapy for first cancer diagnosis: an exploratory feasibility study

Whole-body vibration (WBV) is a feasible and potentially beneficial exercise strategy for managing neuromuscular impairments like decreased strength or flexibility, mobility limitations and bone health in pediatric cancer survivors. However, as starting rehabilitation as early as possible is recommended to preserve physical function, this study investigated the feasibility of WBV for patients receiving cancer treatment for first cancer diagnosis. Eleven patients (various types of cancer, ages 7–17) participated in the supervised WBV intervention concomitant to acute cancer treatment, which involved chemotherapy. Training was implemented as part of a general exercise program and offered 3 days per week during hospitalization (warm-up, four progressive training exercises comprising 60–120 s, 21–27 Hz, 2 mm peak-to-peak-displacement). Feasibility, which was defined as the absence of WBV-related serious adverse events leading to study dropout, was primarily evaluated. Training documentation was additionally analyzed. As a main result, no serious adverse events leading to study dropout were reported. However, two incidents of bleeding (adverse events) were observed in patients with bleeding tendencies and low platelets (thrombocytes < 30,000/μL). After adjusting the platelet count threshold for WBV participation to 30,000/μL, no further incidents occurred. Moreover, due to WBV-related side effects like physical exhaustion, 11% of all training sessions had to be stopped and another 11% required reductions in the vibration load. Patients participated in 48% of the planned sessions. While main reasons for non-attendance were medical issues (35%), only few WBV sessions were missed, not completed or needed modifications due to motivational issues. Consequently, WBV seems to be feasible for inpatient pediatric patients receiving chemotherapy for first cancer diagnosis, given a sufficiently high platelet count of at least 30,000/μL. Although WBV tolerance and training motivation appear high, patient’s reduced medical condition during hospitalization can negatively impact training progression and attendance. Future research is required to confirm our findings on feasibility and to assess efficiency of WBV training for pediatric cancer patients receiving cancer treatment.

Effect of virtual reality-based exercise intervention on sleep quality in children with acute lymphoblastic leukemia and healthy siblings: A randomized controlled trial

OBJECTIVE

Sleep is one of the important measurements of the quality of life for children especially suffering from a chronic illness such as cancer. Our aim was to determine the changes in sleep quality and to investigate the effect of virtual reality-based exercise (VRBE) approaches on sleep in patients with acute lymphoblastic leukemia (ALL) off treatment.

METHOD

The participants (ALL and healthy siblings) were evaluated for sleep quality with polysomnography and "Children's Sleep Habit Questionnaire" before and after 12 weeks. The study randomized into two groups: an exercise group who received VRBE in two days in a week, 45 min of each session for 12 weeks and an control group who were managed with supportive measures. The VRBE comprised of aerobic exercise in four different games by Nintendo Wii Fit Plus®.

RESULTS

This randomized controlled trial was carried out on 38 participants. Before intervention, ALL patients (n = 24) and healthy siblings (n = 14) had similar sleep quality in terms of polysomnography and Children's Sleep Habit Questionnaire findings. After intervention, total time asleep (p = 0.023), respiratory disturbance index of hypopnea (p = 0.005), apnea/hypopnea index (p = 0.008), and number of apnea (p = 0.028) statistically significant improved.

SIGNIFICANCE OF RESULTS

Patients with ALL off treatment had similar values of sleep quality with healthy siblings. Novel types of exercises like VRBE have positive effects on sleep disorders in children with ALL and also healthy siblings. Future studies are needed comparing the different types of interventions.

A Bout of High-Intensity Interval Training (HIIT) in Children and Adolescents during Acute Cancer Treatment-A Pilot Feasibility Study

Low- and moderate-intensity exercise is safe and feasible during childhood cancer treatment. The feasibility of a bout of high-intensity interval training (HIIT) in this population has not been analyzed to date. Pediatric cancer patients aged between 6 and 18 years were selected based on clinical conditions to perform ten sets of 15 s HIIT (>90% of estimated maximal heart rate (HRmax)) and 1 min active recovery on a bicycle ergometer within the first three chemotherapy courses. We assessed safety and feasibility criteria and the following parameters: perceived exertion rate, heart rate, and lactate and adrenaline concentrations. Out of 212 eligible patients, 11 patients aged 13.9 ± 3.6 years (n = 7 ♂) with lymphoma, leukemia, rhabdomyosarcoma, nephroblastoma, and synovial sarcoma completed the bout of HIIT without serious adverse events. During exercise, patients reached a BORG value maxima of 16 ± 1.2, and their heart rates rose from 78 ± 17 beats per minute (bpm) at rest to 178 ± 12 bpm after exercise (90 ± 6% estimated HRmax). The power-to-weight ratio was 2 ± 0.5 W/kg (watt per kilogram). Blood lactate concentrations increased from 1.09 ± 0.50 mmol/L (millimole per liter) at rest to 5.05 ± 1.88 mmol/L post-exercise. Our preliminary data suggest that HIIT is applicable only in a small number of childhood cancer patients. Individually adapted exercise protocols for patients with multiple impairments are needed.

Physical and functional performance assessment in pediatric oncology: a systematic review

BACKGROUND

Research indicates reduced physical performance from diagnosis into survivorship of pediatric cancer patients. However, there is no systematic information or guideline available on the methods to assess physical performance and function in this population. The purpose was to systematically compile and describe assessments of physical performance and function in patients and survivors of pediatric cancer, including cardiorespiratory fitness, muscle strength, speed, balance, flexibility, functional mobility, gait and motor performance test batteries.

METHODS

We searched the databases PubMed, SPORTDiscus, and Cochrane Database and performed abstract and full-text selection of 2619 articles according to the Cochrane Handbook of Systematic Reviews. Information on patients characteristics, assessments, information on validity and reliability, and relevant references was extracted.

RESULTS

In summary, 63 different assessments were found in 149 studies including 11639 participants. Most studies evaluated cardiorespiratory fitness and muscle strength with the majority conducted off treatment. Some outcomes (e.g. speed) and diagnoses (e.g. neuroblastoma) were severely underrepresented. With the exception of gait, leukemia patients represented the largest group of individuals tested.

CONCLUSIONS

Insufficient data and patient heterogeneity complicate uniform recommendations for assessments. Our results support researchers and practitioners in selecting appropriate assessment to meet their specific research questions or individual daily practice needs.

IMPACT

This systematic review includes 149 studies and provides a comprehensive summary of 63 assessments to evaluate cardiorespiratory fitness, muscle strength, speed, balance, flexibility, functional mobility, gait or motor performance test batteries in patients and survivors of pediatric cancer. We present the most studied fields within the pediatric cancer population, which are cardiorespiratory fitness and muscle strength, off treatment phase, and leukemia patients. We propose research priorities by identification of subgroups in terms of cancer type, phase of treatment, and outcome of interest that are underrepresented in studies currently available.

The effects of administered interventions on quality of life of children with cancer in Turkey: A systematic review and meta-analysis

OBJECTIVE

The present systematic review and meta-analysis aimed to analyse the effects of administered interventions on the quality of life of children with cancer in Turkey.

METHODS

The quantitative studies conducted with paediatric oncology patients, analysing the quality of life of Turkish children, and published papers from 2009 to 2019 were searched. Joanna Briggs Institution MAStARI Experimental and Quasi-Experimental Research Control List and Quality Index were used for methodological assessment. Five studies comprising a total of 264 samples were included. Four studies were nonrandomised controlled trials, and one was a quasi-experimental study.

RESULTS

Tests for heterogeneity showed that the studies, which included interventions increasing the quality of life of children with cancer, were heterogeneous. The common effect size of all studies on quality of life was determined as having a strong positive effect.

CONCLUSIONS

This meta-analysis and systematic review contribute to the knowledge of Turkish health care professionals regarding these interventions by producing results with high levels of evidence on the improvement of the quality of life among children with cancer. The present study also significantly raises awareness and encourages health care professionals to implement interventions for the improvement of quality of life among children with cancer.

Biological Aspects of Inflamm-Aging in Childhood Cancer Survivors

Anti-cancer treatments improve survival in children with cancer. A total of 80% of children treated for childhood cancer achieve 5-year survival, becoming long-term survivors. However, they undergo several chronic late effects related to treatments. In childhood cancer survivors a chronic low-grade inflammation, known as inflamm-aging, is responsible for frailty, a condition characterized by vital organ failure and by premature aging processes. Inflamm-aging is closely related to chemotherapy and radiotherapy, which induce inflammation, accumulation of senescent cells, DNA mutations, and the production of reactive oxygen species. All these conditions are responsible for the onset of secondary diseases, such as osteoporosis, cardiovascular diseases, obesity, and infertility. Considering that the pathobiology of frailty among childhood cancer survivors is still unknown, investigations are needed to better understand frailty's biological and molecular processes and to identify inflamm-aging key biomarkers in order to facilitate the screening of comorbidities and to clarify whether treatments, normally used to modulate inflamm-aging, may be beneficial. This review offers an overview of the possible biological mechanisms involved in the development of inflamm-aging, focusing our attention on immune system alteration, oxidative stress, cellular senescence, and therapeutic strategies.

Physical therapy interventions, other than general physical exercise interventions, in children and adolescents before, during and following treatment for cancer

BACKGROUND

Children and adolescents diagnosed with cancer are at high risk of experiencing severe side effects from cancer treatment, many of which are amenable to physical therapy. These side effects can negatively impact a child's quality of life and ability to participate in daily activities (e.g. play and attendance at school). Researchers have evaluated physical therapy interventions in children with cancer and childhood cancer survivors. However, factors such as small sample sizes, varying intervention protocols and differences in cancer types among trials make it difficult to draw conclusions about efficacy.

OBJECTIVES

The primary aim of this review was to evaluate the efficacy of physical therapy interventions - with a specific focus on symptom relief and compensation of therapy-related side effects - on the quality of life of children and adolescents diagnosed with cancer. Participants must be between the ages of 0 and 19 years at the time of the physical therapy intervention study. The intervention may occur prior to, during or following cancer treatment. The intervention must be compared to a control group of children receiving standard care, no physical therapy intervention or a comparison intervention. We have excluded general physical exercise studies where the primary aim was to improve physical fitness through aerobic, anaerobic, resistance exercise or combined physical exercise training regimens (i.e. combined aerobic and resistance exercise regimens). We have also intended to record the occurrence of any adverse effects resulting from physical therapy interventions. The secondary aims were to evaluate the efficacy of physical therapy on impairments of pain, peripheral neuropathy, balance, gait, functional abilities and mobility, motor function and performance, range of motion, strength and fatigue.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, PEDro, ongoing trial registries, conference proceedings and the reference lists of relevant studies and reviews in March 2020. We also contacted oncology rehabilitation researchers working in paediatrics in March 2020 to identify additional studies.

SELECTION CRITERIA

The review included randomised controlled trials (RCTs), cross-over trials, and controlled clinical trials (CCTs) that compared the effects of physical therapy interventions to a control group, and involved children and adolescents diagnosed with cancer between the ages of 0 and 19 years at the time of the intervention. We excluded studies examining general physical exercise interventions where the primary aim was to improve physical fitness through aerobic exercise, resistance exercise or combined physical exercise training regimens (i.e. combined aerobic and resistance exercise regimens).

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

We found no RCTs, cross-over trials or CCTs comparing the effects of physical therapy interventions with a focus on symptom relief and compensation of therapy-related side effects for children and adolescents between the ages of 0 and 19 years.

AUTHORS' CONCLUSIONS

Results demonstrate that the evidence to date is inadequate to inform clinical practice. Recommendations for future research include the need for large-scale, high-quality designs that examine: (1) paediatric populations with same cancer types; (2) similar intervention protocols; (3) long-term outcomes; (4) physical therapy interventions (e.g. electrophysical modalities and sensory interventions); and (5) outcomes commonly impaired in children with cancer (e.g. peripheral neuropathy and gait deficits).

Feasibility of a combined supervised and home-based whole-body vibration intervention in children after inpatient oncological treatment

Purpose

Reduced physical performance due to therapy-related dysfunctions in children diagnosed with cancer contributes to insufficient physical activity levels. It is therefore essential that relevant functions are restored. Whole-body vibration (WBV) training, a neuromuscular stimulating exercise intervention, could have the potential to target those functions adequately. Therefore, the aim of this study was to evaluate the feasibility of a combined supervised and home-based WBV intervention with children after inpatient oncological treatment.

Methods

Eight children aged 6–21 years were included after cessation of their inpatient oncological treatment. They performed a 12-week WBV training including one supervised and two home-based sessions per week according to a standardized training protocol. Feasibility, adherence and compliance to the vibration protocol were documented. Subjective benefits and satisfaction were assessed using a questionnaire.

Results

Study participants attended 84.03 ± 13.09% of WBV sessions. No serious adverse events occurred. Some patients reported side effects partially resulting in modifications of the vibration protocol by therapists. Almost all children regarded the intervention as beneficial.

Conclusion

A combined supervised and home-based WBV intervention with children after inpatient oncological treatment is feasible and safe. The beneficial potential regarding relevant sensory and motor dysfunctions is now to be investigated.

Synthesizing the literature on physical activity among children and adolescents affected by cancer: evidence for the international Pediatric Oncology Exercise Guidelines (iPOEG)

Physical activity (PA), including exercise, is safe and beneficial for children and adolescents affected by cancer. Yet, no efforts have been made to collate the breadth of review and experimental articles exploring the effects of PA in this cohort. Thus, a scoping review of review and experimental articles reporting on the effects of PA for children and adolescents affected by cancer was undertaken. Review and experimental articles published in English, summarizing or reporting on the effects of PA interventions for children and adolescents affected by cancer were included. Articles were identified through prior literature, systematic searching, reference list scanning, stakeholder engagement, and a database update. Data were extracted, collated, assessed for quality (reviews) or risk of bias (experimental articles), and summarized narratively. A total of 1,380 articles were identified; 20 review and 69 experimental articles were included. Articles explored PA behavior, physical, psychosocial, cognitive, and "other" outcomes. Improvements, no change, or mixed results were reported across the majority of outcomes explored. Two PA-related adverse events (e.g., a treatable injury, fatigue) were described. Included articles varied greatly in quality and risk of bias. Findings confirm that PA for children and adolescents affected by cancer is a rapidly growing field. More adequately powered research, focused on priority outcomes, adopting appropriate study designs, and adhering to reporting standards is required. Addressing these gaps will enable a better understanding of the effects of PA. Nevertheless, the literature confirms moving more is beneficial and safe for children and adolescents affected by cancer.

Health-Promoting Lifestyle and Its Predictors in Adolescent Survivors of Childhood Cancer

Background: Cancer survivors are at increased risk of long-term adverse effects related to the disease or treatment. Thus, it is important for cancer survivors to adopt a health-promoting lifestyle (HPL). This study aims to: (1) describe health behavior self-efficacy (HBSE) and HPL of adolescent survivors of childhood cancer, (2) examine the relationships between HBSE, HPL, and various demographic factors, and (3) identify determinants of HPL among adolescent survivors of childhood cancer. Method: A descriptive cross-sectional study was conducted with adolescent survivors of childhood cancer, ranged in age from 11 to 19 years (n = 82). Participants were recruited from pediatric oncology follow-up clinics at two medical centers in southern Taiwan. Data for each participant were collected from questionnaires assessing HBSE and HPL. Results: Only 61% of the adolescent survivors were considered as normal weight. The exercise was the lowest scoring HBSE subscale. Factors associated with better HPL included: education level, HBSE, well-being, and a healthy diet. Specifically, survivors diagnosed with cancer during adolescence exhibited significantly greater self-efficacy with stress management (F = 3.20, p = .04) compared with those diagnosed at pre-school ages. HBSE scores for well-being and a healthy diet were significant predictors of HPL, accounting for 43.8% of the total variance observed. Discussion: Our findings suggest that the age of diagnosis of childhood cancer significantly modulates the frequency of health-promoting behaviors of adolescent survivors. Thus, interventions designed to enhance adolescents' well-being and the management of a healthy diet may enhance HPL in survivors of childhood cancer.

A Randomized Trial of Physical Activity in Children and Adolescents with Cancer

Simple Summary

Malignant diseases and anticancer treatments alter physical activity and performance in children and adolescents. Physical inactivity may cause both early and long-term complications, increasing the disease-associated burden. However, data on the safety and efficacy of physical activity programs in children with cancer are still scarce. In this randomized controlled open-label clinical trial that included 80 children and adolescents with cancer, the six-minute walk test distance (evaluating exercise capacity) was improved in the intervention group (physical activity program) vs. the control group (86 ± 12 m vs. 32 ± 6 m), a significant difference. Several other physical parameters (flexibility, balance, upper and lower limb strength, trunk and abdominal muscle endurance), global self-esteem and parent-reported quality of life were also better in the intervention group. In children and adolescents undergoing treatment for cancer, a physical activity program is safe, improves exercise capacity, and may have persistent physical and psychological benefits.

Abstract

Background: to evaluate the safety and efficacy of a physical activity program (PAP) in children and adolescents with cancer. Methods: children and adolescents with cancer were randomly assigned in a 1:1 ratio to the six-month PAP (intervention group) or to the control group. The first evaluation was performed at the end of the PAP (T0 + 6 mo). At T0 + 6 mo, both groups received the six-month PAP with a second evaluation at T0 + 12 mo. The primary outcome was the evolution of exercise capacity measured using the six-minute walk test (6 MWT) at T0 + 6 mo. Secondary outcomes included PAP safety and changes in other physical functions, self-esteem, and quality-of-life parameters. Results: The trial involved 80 children and adolescents (age range 5.0–18.4 years), of whom 41 were assigned to the interventional group and 39 to the control group. Underlying malignancies were leukemia (39%) and a broad range of solid tumors (61%). No adverse events occurred. At T0 + 6 mo, the evolution of the 6 MWT distance (±SEM) was improved in the intervention group vs. the control group (86 ± 12 m vs. 32 ± 6 m, p < 0.001). Several other physical parameters were significantly improved in the intervention group. Global self-esteem and parent-reported quality-of-life were significantly increased in the intervention group. Analysis at T0 + 12 mo showed persistence of the benefits in the intervention group on exercise capacity evolution (115 ± 18 m vs. 49 ± 11 m, p = 0.004) and on most physical and QoL parameters. Conclusion: In children and adolescents with cancer, a physical activity program is safe, improves exercise capacity, and may have physical and psychological benefits.

Validation of an exercise booklet for children with acute lymphoblastic leukemia

Abstract Introduction: Leukemia is the most common childhood cancer, and acute lymphoblastic leukemia (ALL) accounts for 75 to 80% of all such cases in this population. Survival has increased among children and adolescents due to advances in diagnosis and treatment, with a growing emphasis on the need for rehabilitation to improve functionality and quality of life, mitigating the long-term effects of treatment. Objective: To describe the process of compiling and validating an exercise booklet for children and adolescents during and after treatment for acute lymphoblastic leukemia. Methods: Methodological study using the Delphi technique for validation. The panel of experts consisted of seven healthcare professionals and three mothers of children without ALL. The booklet was evaluated using a form containing 15 items scored on a 5-point Likert scale, and by qualitative assessment. The frequency of the expert ratings, percentage agreement and content validity index (CVI) were presented for each item and the instrument as a whole. Analyses were performed in R 3.5.1 software. Results: The booklet containing stretching, aerobics, strength and relaxation exercises was validated in the second round, reaching 100% consensus. When assessed only by the mothers, 93.33% consensus was achieved in a single round. Conclusion: The exercises booklet was validated for use in the population studied.

Aerobic training versus strength exercises on muscle strength and quality of life for children with acute lymphoblastic leukemia

Background

The treatment for children and adolescents with acute lymphoblastic leukemia (ALL) can lead to multiple adverse effects, including poor physical capacity and muscle weakness. This study aimed to determine which is more effective, aerobic exercises or modified strength training program, on muscle strength and quality of life (QOL) for children with ALL.

Results

In terms of muscle strength, there was a significant difference (P < 0.05) in selected group of muscles elbow flexors, shoulder abductors, hip flexors, knee extensors, and ankle dorsiflexors at both sides in group B compared with group A, whereas there was no significant difference (P > 0.05) between groups on QOL.

Conclusion

The outcomes of the study showed that there was a significant difference in the selected group of muscles at both sides in group B compared with group A; thus, the modified strength training program is more effective for muscle strength of children with ALL than aerobic training, but there was no significant difference between them on QOL.

Social ecological interventions to increase physical activity in children and young people living with and beyond cancer: a systematic review

Objective: To identify the behaviour change techniques and intervention components associated with the promotion of physical activity (PA) for children and young people living with and beyond cancer. Design and main outcome measures: A systematic review and narrative synthesis was conducted on the evidence on PA interventions for children and young people (up to 30 years of age) living with and beyond cancer using a social ecological framework. Results: Out of 12 studies, 8 were shown to change PA. Intervention components included (1) behavioural (Instruction on how to perform the behaviour, credible source, behavioural demonstration and rehearsal), (2) cognitive-emotional (targeting attitude, perceived behavioural control, intentions, resilience and achievement) (3) socio-cultural (family and peer support for PA), (4) environmental (providing access to resources, environmental restructuring, safety), (5) demographic (child, adolescent, young adult or mixed) and (6) medical (tailored exercise depending on age and cancer stage). Conclusions: Interventions designed to increase physical activity participation and adherence during and beyond cancer treatment for young people should integrate psychosocial (behavioural, cognitive-emotional, social), environmental and medical intervention components. Our conceptual model can be used to inform the development of interventions and guides future research objectives and priorities.

Premature Aging in Young Cancer Survivors

Advances in early detection, treatment, and supportive care have resulted in an estimated 16 million cancer survivors who are alive in the United States today. Outcomes have notably improved for children with cancer as well as young adults with hematologic malignancies due, in part, to the intensification of cancer treatment, including the use of hematopoietic cell transplantation. Emerging evidence suggests that these cancer survivors are at risk for premature aging, manifesting as early onset of chronic health conditions and a higher risk of mortality compared with the general population. Although the pathophysiology of premature aging in these survivors has not been fully elucidated, emerging concepts in aging research could help shed light on this phenomenon. Longitudinal studies are needed to better characterize aging in these survivors, setting the stage for much-needed interventions to halt the trajectory of accelerated aging. These efforts will be enhanced through collaborations between translational researchers, clinical oncologists, primary care providers, geriatricians, patient caretakers, and other stakeholders committed to improving the lives of the growing population of survivors.

Evaluation Tools for Physical Activity Programs for Childhood Cancer: A Scoping Review

Research on the benefits of physical activity (PA) in childhood cancer has been translated into a handful of community-based programs. However, to foster further translation, an understanding of how to evaluate participant outcomes would be beneficial to provide feedback to participants and stimulate future research. Such a review would provide a summary of acceptable tools for work in this area. The purpose of this scoping review was to identify the evaluation tools that have been used in PA/exercise studies or programs for childhood cancer. This review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies included in the review used physical and psychosocial evaluation tools within PA and exercise programs or research for childhood cancer. In addition, studies with measures of health behavior such as PA levels and activities of daily living were included. Tools that assessed physical fitness and physical performance were excluded. Information on the types of evaluation tools used, mean age of participants, and type of cancer was extracted. Psychometric properties of each evaluation tool are reported. The most commonly assessed patient outcomes were motor performance, fatigue, well-being, functional mobility, and quality of life. Less commonly reported patient outcomes were hope, self-efficacy, and self-perception. None of the evaluation tools reported in the PA/exercise and pediatric oncology literature assess physical literacy. This review was the first step in a knowledge translation process, identifying evaluation tools that have been used in PA/exercise programs in childhood cancer survivors, that will guide the development and evaluation of current and future community-based programs.

Effects of a group-based physical activity program for pediatric patients with cancer on physical activity and symptom experience: A quasi-experimental study

AIMS

To examine the effects of a group-based physical activity intervention on improvement in physical activity and mitigation of symptom distress among pediatric patients with cancer.

METHODS

Based on convenience sampling, 57 pediatric patients with cancer admitted to the cancer center were included in the intervention group. The control group included 57 pediatric patients with cancer from two other hospitals matched to the patients in the intervention group by age, sex, and diagnosis. A group-based physical activity program was implemented among the children in the intervention group, whereas the children in the control group received standard care. Physical activity and symptoms were measured using the Children's Leisure Time Activities Study Survey-Chinese and using the Memorial Symptom Assessment Scale 10-18 at baseline and after the 12^th exercise session in both the intervention and control groups.

RESULTS

The repeated-measures analysis of variance showed that the main intervention effects on the decrease in light-intensity physical activity and increase in moderate-to-vigorous physical activity were significant between the two groups (P < .001). The group-based physical activity intervention could decrease the scores of psychological symptoms (P < .001), Global Distress Index (P < .001), and physical symptoms (P = .01) when comparing the difference between the two groups before and after the intervention. There was no significant difference in the number of symptoms or the total symptom experience score between the two groups.

CONCLUSION

These findings suggest that a group-based physical activity intervention can promote physical activity and relieve psychological and physical symptom distress among pediatric patients with cancer.

Intervention Protocol: Technology-Based Psychosocial Motivation for Children with Cancer and Their Parents: A Randomized Trial

Objective:

This experimental randomized controlled trial will be to examine the impact of a technology-based psychosocial motivation program on children and families who are being followed up on a diagnosis of cancer.

Methods:

The research is based on the “Transactional Model of Stress and Coping.” This study will be conducted on children with leukemia, aged 9–18 years, and their parents, who will be followed in the consolidation treatment phase in the hematology wards and outpatient clinic of a university hospital. Data collection will consist of the children's and parents' descriptive characteristic form, the Spielberger State Anxiety Inventory for Parents, the State-Trait Anxiety Inventory for Children, the Pediatric Cancer Coping Scale, the Pediatric Quality of Life Inventory, and process evaluation forms. A 10-week program will be implemented for the children in the intervention group through web-based training, coaching interviews and counseling via video mobile calls, mobile messages and children's stories, progressive muscle relaxation and breathing exercises, and imagination interventions. During the same period, parents will also receive web-based training, coaching sessions, counseling, mobile messages, and progressive muscle relaxation exercises.

Results:

It is thought that after the intervention the stress level of the child and the family will decrease, the coping skills of the children will improve, and their quality of life will increase.

Conclusions:

It is thought that the treatment process can be affected positively by providing psychosocial support to children and their families who receive cancer treatment.

Assessment of the effects of walking as an exercise intervention for children and adolescents with cancer: A feasibility study

PURPOSE

To examine the effects of walking exercise on exercise tolerance, fatigue, sleep quality, and quality of life (QOL) for children and adolescents with cancer.

METHODS

A 6-week walking exercise regimen was implemented in pediatric hematological and oncological wards and in clinics of a medical center in Taiwan. A 6-min walk test (6MWT), fatigue, sleep quality, and QOL were measured at baseline and for six subsequent weeks.

RESULTS

Adherence to the walking exercise regimen was achieved by 72-89% of the participants in this study. Significant improvements in exercise tolerance were observed after two weeks and they continued through week 6 (F = 17.07, p < 0.001). Both cognitive fatigue and general fatigue were significantly improved after six weeks of walking exercise (t = 2.41, p = 0.02; t = 2.76, p = 0.01), while sub-scores for sleep/rest fatigue did not improve. No significant impact on sleep quality or QOL was observed.

CONCLUSIONS

Walking exercise is a feasible and tolerable intervention that should be considered for children and adolescents with cancer. Here, a 6-week walking exercise regimen increased exercise tolerance and improved fatigue. We recommend that walking exercise should be promoted during hospitalization and at home to alleviate fatigue.

Whole-Body Vibration Training Designed to Improve Functional Impairments After Pediatric Inpatient Anticancer Therapy: A Pilot Study

PURPOSE

To assess a whole-body vibration (WBV) intervention for children after cancer treatment.

METHODS

Eleven children after inpatient anticancer therapy participated in a 12-week supervised WBV intervention, which consisted of one 9- to 13-minute WBV session per week, with 5 to 9 minutes' overall vibration time. Feasibility was defined as the ability to participate in WBV training without reporting adverse events. The number of offered and completed training sessions, program acceptance, and measures of function were assessed.

RESULTS

Nine participants completed the WBV intervention without any WBV-related adverse events. The adherence rate was 87.96%. Only minor side effects were reported and there was general program acceptance. We found indications that WBV has positive effects on knee extensor strength and active ankle dorsiflexion range of motion.

CONCLUSIONS

WBV was feasible, safe, and well received among children after inpatient anticancer therapy. No health deteriorations were observed. Positive effects need to be confirmed in future trials.

Premature Physiologic Aging as a Paradigm for Understanding Increased Risk of Adverse Health Across the Lifespan of Survivors of Childhood Cancer

The improvement in survival of childhood cancer observed across the past 50 years has resulted in a growing acknowledgment that simply extending the lifespan of survivors is not enough. It is incumbent on both the cancer research and the clinical care communities to also improve the health span of survivors. It is well established that aging adult survivors of childhood cancer are at increased risk of chronic health conditions, relative to the general population. However, as the first generation of survivors age into their 50s and 60s, it has become increasingly evident that this population is also at risk of early onset of physiologic aging. Geriatric measures have uncovered evidence of reduced strength and speed and increased fatigue, all components of frailty, among survivors with a median age of 33 years, which is similar to adults older than 65 years of age in the general population. Furthermore, frailty in survivors independently increased the risk of morbidity and mortality. Although there has been a paucity of research investigating the underlying biologic mechanisms for advanced physiologic age in survivors, results from geriatric populations suggest five biologically plausible mechanisms that may be potentiated by exposure to cancer therapies: increased cellular senescence, reduced telomere length, epigenetic modifications, somatic mutations, and mitochondrial DNA infidelity. There is now a critical need for research to elucidate the biologic mechanisms of premature aging in survivors of childhood cancer. This research could pave the way for new frontiers in the prevention of these life-changing outcomes.

Diet and exercise interventions for pediatric cancer patients during therapy: tipping the scales for better outcomes

Obesity at diagnosis is a negative prognostic indicator for several pediatric cancers including acute leukemia and bone tumors. Incidence of obesity in children has increased three-fold over the past 2 decades, and causes for this include poor diet, excessive caloric intake, and lack of physical activity, which are collectively referred to as energy balance-related behaviors. Few energy balance interventions have been implemented in pediatric cancer patients during treatment, and here we will probe the rationale for pursuing such studies. The need to modify composition of calories consumed and to identify specific beneficial exercise regimens will be discussed, relative to weight reduction or management.

A Prototype Exercise-Empowerment Mobile Video Game for Children With Cancer, and Its Usability Assessment: Developing Digital Empowerment Interventions for Pediatric Diseases

BACKGROUND

Medical advances continue to improve morbidity and mortality of serious pediatric diseases, including cancer, driving research addressing diminished physical and psychological quality of life in children with these chronic conditions. Empowerment enhances resilience and positively influences health, disease, and therapy understanding. We describe the development and usability assessment of a prototype Empower Stars! mobile video game grounded in behavioral and exercise theories with the purpose of coupling physical exercise with empowerment over disease in children with cancer.

METHODS

Academic faculty, health-care providers, and community video game developers collaborated in this project. The iPadAir was selected as a delivery platform for its accelerometer and gyroscope features facilitating exercise design. Unity multiplatform technology provided animation and audiovisual features for immediate player feedback. Javascript, C#, Photoshop, Flash, and SketchUp were used for coding, creating graphical assets, Sprite sheets, and printing files, respectively. 3D-printed handles and case backing were used to adapt the iPad for physical exercise. Game usability, engagement, and enjoyment were assessed via a multilevel study of children undergoing cancer chemotherapy, their parents, and pediatric cancer health-care providers. Feedback crucial for ongoing game development was analyzed.

RESULTS

A prototype Empower Stars! mobile video game was developed for children 7-14 years old with cancer. Active, sedentary, educational, and empowerment-centered elements intermix for 20 min of exercise within a 30 min "one-day treatment" gameplay session involving superheroes, space exploration, metaphorical cancer challenges, life restoration on a barren planet, and innumerable star rewards. No player "dies." Usability assessment data analyses showed widespread enthusiasm for integrating exercise with empowerment over cancer and the game itself. Favorite elements included collecting star rewards and planet terraforming. Traveling in space and the Healthy Food Choice game were least liked. The need for improved gameplay instructions was expressed by all groups. The usability study provided essential feedback for converting the prototype into alpha version of Empower Stars!

CONCLUSION

Adapting exercise empowerment-promoting video game technology to mobile platforms facilitates usability and widespread dissemination for children with cancer. We discuss broader therapeutic applicability in diverse chronic pediatric diseases, including obesity, asthma, cystic fibrosis, diabetes, and juvenile idiopathic arthritis.

Ketogenic Diet and Cancer-a Perspective

Research of the last two decades showed that chronic low-grade inflammation, elevated blood glucose and insulin levels may play role in the onset of a number of non-communicable diseases such as type 2 diabetes and some forms of cancer. Regular exercise and fasting can ameliorate high blood glucose and insulin levels as well as increase the concentration of plasma ketone bodies. These, in consequence, may lead to reduction of inflammation. Exercise or severe restriction of caloric intake is not always advisable for patients, in particular those suffering from cancer. The ketogenic diet (KD), characterized by high fat, moderate protein and very low carbohydrate composition can evoke a physiological state similar to that triggered by exercise or fasting. These attributes of KD prompted its possible use in treatment of a number of metabolic diseases, including several types of malignancies. Although results from clinical studies employing KD in the treatment of cancer are still limited, the results obtained from animal models are encouraging and show that KD presents a viable option as an adjunct therapy for cancer.

Physical Activity in Long-term Survivors of Acute Lymphoblastic Leukemia in Childhood and Adolescence: A Cross-sectional Cohort Study

Inadequate physical activity (PA) and elevated overweight/obesity (OW/OB) rates are common in survivors of cancer in childhood, especially acute lymphoblastic leukemia (ALL). Bony morbidity, including fractures, is also prevalent among survivors of ALL. This study examined the interrelationships of PA, measured in hours by the Habitual Activity Estimation Scale; OW/OG, defined by body mass index; and fractures (yes/no) in survivors of ALL (n=75) more than 10 years after diagnosis. All had been treated using protocols of the Dana Farber Cancer Institute Childhood ALL Consortium. The median age was 21.15 years and time from diagnosis 15.07 years, and 27 subjects had experienced fractures. More than 30% of the total sample were OW/OB. There was no correlation of body mass index with present PA. There were no significant differences between those with/without fractures in terms of age, sex, time from diagnosis, and the prevalence of OW/OB. Subjects with fractures during treatment reported more total activity on typical weekend days than those without fractures (mean 8.8 vs. 6.9 h, P<0.01). There was no significant difference on weekdays. Higher activity on weekends suggests that fractures may have occurred more commonly in those who had a more active lifestyle before, during, and after treatment.

Investigation of the Effects of an Exercise Program on Physical Functions and Activities of Daily Life in Pediatric Hematopoietic Stem Cell Transplantation

BACKGROUND

The aim of this study was to determine the effectiveness of an implemented exercise program for children throughout the hematopoietic stem cell transplantation (HSCT) process.

PROCEDURE

Twenty-two children aged between 3 and 17, who were earlier selected for HSCT, were divided into two groups-intervention and control. Children's physical function, functional performance, and activities of daily life (ADL) were assessed before HSCT, at discharge, and 1 month later. The exercise program, which consisted of strengthening, endurance, stretching, and relaxation exercises, was implemented to the intervention group for 5 days a week throughout hospitalization; and these exercises were given as home program at discharge.

RESULTS

The results of the supervised exercise program during hospitalization showed that the children's physical function and functional performance increased statistically significantly in the intervention group (P < 0.05) and decreased statistically significantly in the control group (P < 0.05). For the ADL, no difference was found between the two groups (P ˃ 0.05).

CONCLUSIONS

The present study determined that the exercise program had positive effects throughout the HSCT process, but these effects did not continue during the follow-up period. Exercise programs implemented by physiotherapists are important for children undergoing HSCT, and after transplantation it is necessary to continue supervised exercise program during follow-up.

Physical activity and health-related quality of life in pediatric cancer patients following a 4-week inpatient rehabilitation program

PURPOSE

Chronic health conditions and impaired quality of life are commonly experienced in childhood cancer survivors. While rehabilitation clinics support patients in coping with the disease, studies evaluating an inpatient rehabilitation program on promoting physical activity (PA) and health-related quality of life (HRQoL) are missing.

METHODS

A 4-week inpatient rehabilitation program was prospectively evaluated. One hundred fifty patients with leukemia or lymphoma (N = 86), brain tumors (N = 38), and sarcomas (N = 26) were enrolled on average 17 months after cessation of acute medical treatment. PA amount and cadence (indicating the intensity of walking activity) using the StepWatch™ 3 Activity Monitor and HRQoL global and physical well-being scores using the KINDL(®) questionnaire were assessed before, immediately after, and 6 and 12 months following the program and analyzed using multiple linear mixed models.

RESULTS

Significant effects on PA were only found at 12-month follow-up for amount and cadence variables (all p < 0.05). While leukemia and lymphoma patients revealed the highest PA level throughout the study, rehabilitation effects were more pronounced for cadence variables in brain tumor and sarcoma patients. The rehabilitation program had immediate (t = 4.56, p < 0.001) and sustainable effects on HRQoL global scores (6-month follow-up, t = 4.08, p < 0.001; 12-month follow-up, t = 3.13, p < 0.006).

CONCLUSIONS

Immediate and sustainable increases in HRQoL indicate that a 4-week rehabilitation program is beneficial for improving psychosocial well-being, while the significant increase in PA levels could be related to general recovery as well. The lack of a control group hampers the evaluation of the rehabilitation program on promoting PA levels in pediatric cancer patients.
