Effectiveness of a dose-graded aerobic exercise regimen on cardiopulmonary fitness and physical performance in pediatric survivors of acute lymphoblastic leukemia: a randomized clinical trial. J Cancer Surviv 2024:10.1007/s11764-024-01534-1. [PMID: 38267738 DOI: 10.1007/s11764-024-01534-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Accepted: 01/08/2024] [Indexed: 01/26/2024]
Abstract
PURPOSE To determine whether a 12-week supervised dose-graded aerobic exercise (D-GAE) training, when implemented in conjunction with traditional rehabilitation, could help pediatric survivors of acute lymphoblastic leukemia (ALL) enhance their cardiopulmonary capacity and improve their physical performance. METHODS Fifty-eight pediatric survivors of ALL (age 13.78 ± 2.47 years; boys 60.34%) were assigned at random to either undergo the D-GAE in addition to the traditional physical rehabilitation (D-GAE group; n = 29) or the traditional physical rehabilitation solely (control group; n = 29). The cardiopulmonary fitness (peak oxygen uptake (VO2peak), ventilatory equivalent (VEq/VO2), minute ventilation (VE, L/min), oxygen pulse (O2P), maximum heart rate (HRmax), 1-min heart rate recovery (HRR1), and respiratory exchange ratio (RER)) and physical performance (6-min walk test (6-MWT), timed up and down stairs (TUDS), and 4 × 10-m shuttle run test (4 × 10mSRT)) were assessed on the pre- and post-intervention occasions. RESULTS The mixed-model ANOVA revealed a meaningful increase of VO2peak (P = .002), VE (P = .026), O2P (P = .0009), HRmax (P = .004), and HRR1 (P = .011), and reduction of VEq/VO2 (P = .003) and RER (P = .003) in the D-GAE group compared with the control group. Besides, the analysis detected a favorable increase in the physical performance for the D-GAE group (6-MWT (P = .007), TUDS (P < .001), 4 × 10mSRT (P = .009)). CONCLUSION A 12-week D-GAE program in conjunction with traditional rehabilitation holds promise in enhancing cardiopulmonary fitness and improving the physical performance of pediatric survivors of ALL. Clinicians and physical rehabilitation professionals can, therefore, integrate the D-GAE into the traditional rehabilitation protocols for such a patient population to optimize their cardiopulmonary fitness and physical function, while also facilitating a gradual transition to practice and adaption. IMPLICATIONS FOR CANCER SURVIVORS The favorable outcomes of this study bolster the inclusion of D-GAE as a crucial element in the care and rehabilitation of pediatric survivors of ALL. By embracing these findings, healthcare professionals and oncologists can contribute to mitigating the long-term cardiopulmonary and physical complications associated with cancer treatments and fostering a state of enhanced well-being and increased physical activity among survivors.

Abstract
ABSTRACT There is a gap in the literature on the best treatment of clinical sequelae within adolescent and young adult pediatric cancer populations. Children, adolescents, and young adults are at risk for a multitude of immediate and late effects of their disease and treatment that warrant a comprehensive, multidisciplinary team approach to optimize care. Sports medicine providers are well-equipped with their background to join the oncology rehabilitation team in diagnosing and managing cancer-related impairments to help these populations live a healthier and more active lifestyle. In this manuscript, four essential clinical components to consider when returning children, adolescents, and young adults with cancer history to physical activity are discussed: chemotherapy-induced peripheral neuropathy, cardiotoxicity, nutritional deficiencies, and deconditioning.

Abstract
Exercise intolerance is a common adverse effect of childhood cancer, contributing to impaired health and well-being. While reduced aerobic fitness has been attributed to central cardiovascular deficiencies, the involvement of peripheral musculature has not been investigated. We studied peripheral muscle function in children following cancer treatment using noninvasive phosphorus-31 magnetic resonance spectroscopy. Ten acute lymphoblastic leukemia (ALL) and 1 lymphoma patient 8 to 18 years of age who completed treatment 6 to 36 months prior and 11 healthy controls participated in the study. Phosphorus-31 magnetic resonance spectroscopy was used to characterize muscle bioenergetics at rest and following an in-magnet knee-extension exercise. Exercise capacity was evaluated using a submaximal graded treadmill test. Both analysis of variance and Cohen d were used as statistical methods to determine the statistical significance and magnitude of differences, respectively, on these parameters between the patient and control groups. The patients treated for ALL and lymphoma exhibited lower anaerobic function ( P =0.14, d =0.72), slower metabolic recovery ( P =0.08, d =0.93), and lower mechanical muscle power ( d =1.09) during exercise compared with healthy controls. Patients demonstrated lower estimated VO 2peak (41.61±5.97 vs. 47.71±9.99 mL/min/kg, P =0.11, d =0.76), lower minutes of physical activity (58.3±35.3 vs. 114.8±79.3 min, P =0.12, d =0.99) and higher minutes of inactivity (107.3±74.0 vs. 43.5±48.3 min, d =1.04, P <0.05). Children treated for ALL and lymphoma exhibit altered peripheral skeletal muscle metabolism during exercise. Both deconditioning and direct effects of chemotherapy likely contribute to exercise intolerance in this population.

Abstract
Acute Lymphoblastic Leukemia (ALL) is the most common cancer in children and toxicities related to treatment are common. One of these adverse effects is related to the musculoskeletal system and especially to gross motor skills that allow body movements: walking, running, jumping, and balance. This systematic review aims to describe gross motor impairments in pediatric patients with ALL during and after chemotherapeutic treatment and to identify the most commonly used tools for their assessment. Multiple electronic databases were searched for observational studies describing gross motor skills in children with ALL and the assessment tool used. The STROBE checklist was used to assess the reporting quality of each study. Ten studies were included in this review with assessments of gross motor skills in children with ALL undergoing treatment and survivors. Evidence suggests impairments in the performance of daily life activities during intensification and maintenance and persists up to 5 to 6 years after treatment´s cessation. Balance problems are noted at the start of treatment when the cumulative dose of vincristine is low and, in the survivors, it was the most reported alteration. These skills are essential for an adequate performance of children in daily life activities, recreation and leisure. We emphasize the need to assess gross motor skills and implement interventions that include physiotherapy and occupational rehabilitation in children with ALL.

Abstract
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.

Abstract
BACKGROUND Adult childhood cancer survivors are at risk for frailty, including low muscle mass and weakness (sarcopenia). Using peripheral blood mitochondrial DNA copy number (mtDNAcn) as a proxy for functional mitochondria, this study describes cross-sectional associations between mtDNAcn and sarcopenia among survivors. METHODS Among 1762 adult childhood cancer survivors (51.6% male; median age = 29.4 years, interquartile range [IQR] = 23.3-36.8), with a median of 20.6 years from diagnosis (IQR = 15.2-28.2), mtDNAcn estimates were derived from whole-genome sequencing. A subset was validated by quantitative polymerase chain reaction and evaluated cross-sectionally using multivariable logistic regression for their association with sarcopenia, defined by race-, age-, and sex-specific low lean muscle mass or weak grip strength. All statistical tests were 2-sided. RESULTS The prevalence of sarcopenia was 27.0%, higher among female than male survivors (31.5% vs 22.9%; P < .001) and associated with age at diagnosis; 51.7% of survivors with sarcopenia were diagnosed ages 4-13 years (P = .01). Sarcopenia was most prevalent (39.0%) among central nervous system tumor survivors. Cranial radiation (odds ratio [OR] = 1.84, 95% confidence interval [CI] = 1.32 to 2.59) and alkylating agents (OR = 1.34, 95% CI = 1.04 to 1.72) increased, whereas glucocorticoids decreased odds (OR = 0.72, 95% CI = 0.56 to 0.93) of sarcopenia. mtDNAcn decreased with age (β = -0.81, P = .002) and was higher among female survivors (β = 9.23, P = .01) and among survivors with a C allele at mt.204 (β = -17.9, P = .02). In adjusted models, every standard deviation decrease in mtDNAcn increased the odds of sarcopenia 20% (OR = 1.20, 95% CI = 1.07 to 1.34). CONCLUSIONS A growing body of evidence supports peripheral blood mtDNAcn as a biomarker for adverse health outcomes; however, this study is the first to report an association between mtDNAcn and sarcopenia among childhood cancer survivors.

Abstract
Skeletal muscle (muscle) is essential for physical health and for metabolic integrity, with sarcopenia (progressive muscle mass loss and weakness), a pre-curser of aging and chronic disease. Loss of lean mass and muscle quality (force generation per unit of muscle) in the general population are associated with fatigue, weakness, and slowed walking speed, eventually interfering with the ability to maintain physical independence, and impacting participation in social roles and quality of life. Muscle mass and strength impairments are also documented during childhood cancer treatment, which often persist into adult survivorship, and contribute to an aging phenotype in this vulnerable population. Although several treatment exposures appear to confer increased risk for loss of mass and strength that persists after therapy, the pathophysiology responsible for poor muscle quantity and quality is not well understood in the childhood cancer survivor population. This is partly due to limited access to both pediatric and adult survivor muscle tissue samples, and to difficulties surrounding non-invasive investigative approaches for muscle assessment. Because muscle accounts for just under half of the body's mass, and is essential for movement, metabolism and metabolic health, understanding mechanisms of injury responsible for both initial and persistent dysfunction is important, and will provide a foundation for intervention. The purpose of this review is to provide an overview of the available evidence describing associations between childhood cancer, its treatment, and muscle outcomes, identifying gaps in current knowledge.

Abstract
OBJECTIVE To explore the cardio-respiratory response to exercise and examine the relationships among specific measures of cardio-respiratory function, energy expenditure (EE), fatigue and adiposity in children survivors of acute lymphoblastic leukaemia (ALL). METHODS Seventy survivors of ALL (13.31 ± 2.60 years) and 34 controls from the siblings (12.71 ± 2.36 years) participated and were assessed for submaximal and maximal exercise capacity, body composition, EE and fatigue. RESULTS ALL survivors had significantly lower submaximal (VO2 ; p = 0.002) and maximal (VO2peak ; p ˂ 0.001) cardio-respiratory capacity than their controls. At the submaximal exercise test, EE was significantly lower in ALL survivors (p < 0.001), but the heart rate (HR) was significantly higher (p = 0.005). The VO2 and HR were significantly correlated [r (95%CI) = 0.689 (0.542 to 0.795), p < 0.001]. The VO2peak negatively associated with adiposity [r (95%CI) = -0.368 (-0.554 to -0.145), p = 0.002]. Fatigue significantly correlated with the VO2peak [r (95%CI) = 0.581 (0.401 to 0.718), p < 0.001] and adiposity [r (95%CI) = -0.303 (-0.502 to 0.073), p = 0.012]. CONCLUSION Children survivors of ALL experience low cardio-respiratory fitness within 5-year off-chemotherapy. Associations exist between measures of cardio-respiratory fitness, EE, fatigue and adiposity. However, it has not yet been proven whether these are cause or effect.

Abstract
PURPOSE This study explored neuromuscular mechanisms and clinical measures that contribute to countermovement jump performance in survivors of childhood acute lymphoblastic leukemia (ALL CCS) compared to age- and sex-matched peers. METHODS This exploratory cross-sectional observational study examined 12 participants, six ALL CCS and six age- and sex-matched peers (7-16 years). During a countermovement jump, rates of muscle activation of lower leg muscles were measured with electromyography, and joint torques and peak jump height with force plates and a motion capture system. Clinical measures included muscle extensibility, balance, and mobility measured by active ankle dorsiflexion, Bruininks-Oseretsky Motor Proficiency (BOT-2), and Timed Up and Go (TUG) tests. RESULTS Compared to peers, ALL CCS demonstrated reduced gastrocnemius muscle extensibility and tibialis anterior rate of muscle activation, decreased jump height, and poorer performance on the BOT-2 and TUG. Jump height was significantly correlated with clinical measures of the BOT-2 and TUG. CONCLUSION These ALL CCS demonstrated neuromuscular impairments that may impact jump performance, an essential childhood physical activity. Further research is needed to explore intervention strategies to improve the neuromuscular mechanisms that contribute to high-level gross motor skills in ALL CCS.

Abstract
BACKGROUND Children with acute lymphoblastic leukemia (ALL) experience detrimental effects on motor function during and after chemotherapy. The objective of this systematic review was to evaluate the effect of exercise and motor interventions on physical activity and motor outcomes of children with ALL during and after chemotherapy. METHODS Ten databases were searched. Nineteen studies were included: 11 randomized clinical trials (RCT), 2 controlled clinical trials (CCT), and 6 cohort studies. RESULTS Participants included 508 children with ALL. Between-group results from RCTs and CCTs supported that exercise and motor intervention improved: fatigue during acute chemotherapy; physical activity, range of motion (ROM), strength, bone mineral density, aerobic capacity, and fatigue during maintenance chemotherapy; functional mobility, ROM, strength, and aerobic capacity during post-treatment survivorship; and participation, physical activity, ROM, strength, and coordination during multiple-phase interventions. CONCLUSION Low quality evidence supports the efficacy of motor and exercise interventions for children and adolescents with ALL.

Abstract
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.

Abstract
Pediatric acute lymphoblastic leukemia survivors are at risk for developing neurocognitive late effects following intensive medical treatment. Motor impairments have been highlighted as a common neurocognitive late effect, including fine-, gross-, and visual-motor skills. The severity of these motor deficits is variable in the existing literature, warranting additional investigations with more homogenous samples. In addition, there is an even greater paucity regarding the interrelations between motor deficits and the impact motor challenges may have on other domains of functioning, such as academics. Therefore, the present study aimed to characterize motor functioning in children who were treated for acute lymphoblastic leukemia with chemotherapy (n = 13) in comparison to healthy controls (n = 13). Additionally, this study investigated the relationship between primary (e.g., visual-spatial, fine-motor), secondary (e.g., visual-motor), and tertiary (e.g., academics) skills. The results revealed that oncology survivors had significantly lower fine- and gross-motor skills compared to healthy controls. No significant differences were observed between the groups on visual-perception and visual-motor tasks. Fine-motor functioning was significantly associated with visual-motor functioning in ALL survivors. Motor skills were not related to academic outcomes. The present findings provide evidence for motor impairments in pediatric ALL survivors, along with initial findings highlighting the cascading effect of primary motor impairments on other cognitive domains. This research sheds light on the need for clinical screening and intervention of motor skills in the survivorship population. Future research is warranted to examine the effect of motor deficits on cognitive and psychosocial functioning in pediatric oncology.

Abstract
This study evaluates the physical and psychosocial effects of an inpatient exercise program for children and adolescents undergoing hematopoietic stem cell transplantation (HSCT). Participants (n = 70) were randomized to an exercise intervention (IG: resistance, endurance, and flexibility training) or a non-exercise control group (CG: mental and relaxation training). Pre- (prior hospital admission; T0) and post- (day of discharge; T1) measurements included maximal isometric knee extension strength (KES; strain gauge force transducer), hand grip strength (HGS; JAMAR dynamometer), distance walked in 6 min (6MWD; 6-minute walk test), quality of life (QoL; KINDL-R) and medical parameters. Fifty-seven patients (IG: n = 28; 11.0 (5-17) years; CG: n = 29; 12.0 (6-18) years) completed the study. During hospitalization the IG and CG attended on average 3.1 (2-4) or 2.9 (0.3-4) training sessions weekly. KES, 6MWD, and HGS significantly decreased (p < 0.05) in the CG, while there were no changes in the IG. Pre- to post-changes in 6MWD and HGS differed significantly between groups (p < 0.05). QoL declined in both groups (p < 0.05). Our results indicate that a moderate exercise program is feasible and might counteract a treatment-associated decline of physical performance.

Abstract
PURPOSE The number of pediatric cancer survivors has increased dramatically over recent decades. Prior studies involving pediatric cancer survivors have reported reduced physical activity and fitness levels. Thus, the aim of this meta-analysis was to synthesize previous findings on physical activity and fitness levels of pediatric cancer survivors, who had completed cancer treatment and are in complete remission compared with age-matched, non-athletic healthy controls with no history of cancer diagnosis. METHODS Three electronic databases (PubMed, Web of Science, and EBSCO) were searched using a combination of 24 terms. Observational studies examining the post-treatment physical activity and/or fitness levels of pediatric cancer survivors compared with that of non-cancer controls and published in peer-reviewed, English-language journals before August 22, 2018 were eligible. Random-effect models were used in Comprehensive Meta-Analysis software for effect-size estimations of eight studies for physical activity and eight for fitness. RESULTS The studies included a total sample of 2628; 1413 pediatric cancer survivors and 1215 non-cancer controls. Both physical activity and fitness were significantly lower in childhood cancer survivors than in non-cancer controls (g = - 0.889; 95% confidence interval [CI] = - 1.648 - 0.130; p = 0.022) and (g = - 1.435; 95% CI = - 2.615 - 0.225; p = 0.017), respectively, with high heterogeneity. CONCLUSIONS Pediatric cancer sequelae and its treatment may limit participation in physical activity and fitness activities by survivors of pediatric cancer. Accentuating the need to incorporate physical activity and fitness into treatment protocols and post-treatment recommendations may improve pediatric cancer survivors' health and well-being.

Abstract
BACKGROUND Up to 43% of survivors of pediatric acute lymphoblastic leukemia (ALL) may exhibit fine-motor problems. Information on manual dexterity in this cohort is still limited. OBJECTIVES We tested survivors of childhood ALL treated with chemotherapy-only for fine-motor function in terms of drawing and handwriting abilities using a Digitizing Tablet (DT) with three tasks for drawing and handwriting of varying complexity, for ataxia using the International Cooperative Ataxia Rating Scale (ICARS), and for tremor and hand-eye coordination using the Nine Hole Steadiness Tester (NHST). RESULTS We examined a cohort of non-irradiated survivors (n = 31) after a median time of 3.5 years after end of therapy. In all tasks of the DT the cohort demonstrated significant (p < 0.05) impairment of speed, automation, and variability in at least two tasks and significantly more pressure. Impaired speed (SPV) inversely correlated with lag time since end of therapy. Dexterity performance of six survivors (19%) lay below the 5th percentile. No survivor exhibited ataxia, tremor, or impaired hand-steadiness. CONCLUSION Despite the absence of gross ataxia, tremor, and impaired hand-eye coordination, we nevertheless detected significant fine-motor impairment in a relevant number of survivors of childhood ALL. Prospective studies are needed to reveal the pathophysiological underpinnings and genetic risk factors for development of such deficits due to ALL and its treatment.

Abstract
BACKGROUND Impairment of health-related physical fitness (HRPF) in survivors of acute lymphoblastic leukemia has been shown. However, evidence of impairment in survivors of other pediatric malignancies and possible risk factors is limited. PARTICIPANTS AND METHODS HRPF of 17 survivors of pediatric acute myeloid leukemia (AML), 26 survivors of neuroblastoma (NBL), 28 survivors of Wilms tumor (WT) (median age 28.8 [18.8-62.6] years) after a median follow-up time of 24.5 (6.5-43.6) years, and 74 healthy controls (median age 26.9 [17.9-61.7] years). Risk factors were investigated. Testing included submaximal cardiovascular endurance (6-Minute Walk Test (6 MWT), flexibility, and muscle strength. RESULTS Results are expressed as mean (standard error). Survivors scored significantly lower than controls on the 6 MWT (588 ± 6.1 m vs. controls 611 ± 6.0 m; P = 0.008), on side flexion of the trunk (20.1 ± 0.4 cm vs. controls 22.4 ±0.4 cm; P < 0.001), and on vertical jump (39.7 ± 0.8 cm vs. controls 43.8 ± 0.8 cm; P < 0.001). Survivors of AML had lower scores on the 6 MWT (563 ± 12.4 m) than survivors of NBL (585 ± 9.9 m) and survivors of WT (606 ± 9.6 m), P = 0.046. Being a survivor, higher body mass index (BMI) and no participation in sports were independently associated with lower scores on the 6 MWT. CONCLUSION Survivors of NBL, WT, and especially AML have impaired HRPF. Higher BMI and physical inactivity at adult age appeared prominent risk factors for impaired HRPF in these survivors.

Abstract
A decreased physical fitness has been reported in patients and survivors of acute lymphoblastic leukemia (ALL). This is influenced by the negative effects of the disease and by the treatments of childhood cancer. In the past, children were advised to recover in bed, and to take as much relax as possible. Nowadays, it is considered that too much immobility may result in a further decrease of physical fitness and functioning. Exercise training for ALL children has frequently been reported to improve physical fitness and the well-being of the children, since it prevents the negative effects of a sedentary life-style, such as obesity and a poor skeletal health. In recent years, different studies and protocols on this subject has become available for children and young adults with cancer, both during and after treatment. The efficacy of recent physical exercise training interventions, that act on several ALL impairments in children such as skeletal, musculoskeletal, neuromuscular, cardiopulmonary and cardiovascular systems, fatigue, body balance disorders and metabolism alterations have been examined. These side effects might be prevented or significantly reduced by introducing a physical exercise program during or shortly after cancer treatment. Several interventions are discussed and presented for each impairment, reducing their level caused by the disease and thus suggesting the importance of physical training activity in ameliorating the children quality of life.

Abstract
Many cancer therapies produce toxic side effects whose molecular mechanisms await full elucidation. The most feared and studied side effect of chemotherapeutic drugs is cardiotoxicity. Also, skeletal muscle physiology impairment has been recorded after many chemotherapeutical treatments. However, only doxorubicin has been extensively studied for its side effects on skeletal muscle. Chemotherapeutic-induced adverse side effects are, in many cases, mediated by mitochondrial damage. In particular, trastuzumab and sunitinib toxicity is mainly associated with mitochondria impairment and is mostly reversible. Vice versa, doxorubicin-induced toxicity not only includes mitochondria damage but can also lead to a more robust and extensive cell injury which is often irreversible and lethal. Drugs interfering with mitochondrial functionality determine the depletion of ATP reservoirs and lead to subsequent reversible contractile dysfunction. Mitochondrial damage includes the impairment of the respiratory chain and the loss of mitochondrial membrane potential with subsequent disruption of cellular energetic. In a context of increased stress, AMPK has a key role in maintaining energy homeostasis, and inhibition of the AMPK pathway is one of the proposed mechanisms possibly mediating mitochondrial toxicity due to chemotherapeutics. Therapies targeting and protecting cell metabolism and energy management might be useful tools in protecting muscular tissues against the toxicity induced by chemotherapeutic drugs.

Abstract
The population of adult survivors of childhood cancer continues to grow as survival rates improve. Although it is well established that these survivors experience various complications and comorbidities related to their malignancy and treatment, this risk is modified by many factors that are not directly linked to their cancer history. Research evaluating the influence of patient-specific demographic and genetic factors, premorbid and comorbid conditions, health behaviors, and aging has identified additional risk factors that influence cancer treatment-related toxicity and possible targets for intervention in this population. Furthermore, although current long-term follow-up guidelines comprehensively address specific therapy-related risks and provide screening recommendations, the risk profile of the population continues to evolve with ongoing modification of treatment strategies and the emergence of novel therapeutics. To address the multifactorial modifiers of cancer treatment-related health risk and evolving treatment approaches, a patient-centered and risk-adapted approach to care that often requires a multidisciplinary team approach, including medical and behavioral providers, is necessary for this population.

Abstract
Chemotherapeutic agents (CAs) can independently promote skeletal muscle dysfunction, fatigue and wasting with mitochondrial toxicity implicated as a possible mechanism. Thus, we aimed to characterise the effects of various CAs on mitochondrial function, viability and oxidant production in C2C12 myoblasts and myotubes. All CAs significantly reduced the viable mitochondrial pool but did not affect mitochondrial functional parameters. Doxorubicin and oxaliplatin increased oxidant production in myotubes while all CAs, except for irinotecan, increased oxidant production in myoblasts and reduced myotube diameter. Our data demonstrate CAs mito-toxic effects, highlighting the potential for mitochondria-protective therapeutics to address chemotherapy-induced skeletal muscle damage.

Abstract
OBJECTIVE To analyze the relation between platelet counts, intensities of physical therapy (PT) and occupational therapy (OT) services received, and frequencies of bleeding complications in children undergoing hematopoietic stem cell transplant (HSCT) during a period of severe thrombocytopenia. DESIGN Retrospective review study. SETTING Tertiary care hospital. PARTICIPANTS Children (N=63; age, <18y) hospitalized for HSCT in 2010 and 2011 who received PT and OT services while markedly thrombocytopenic (platelet count, ≤50K/mcL). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Intensities of PT and OT interventions, patients' platelet counts on specific therapy days, and any bleeding events (minor or major) that occurred during or shortly after rehabilitation interventions. RESULTS Sixty-two patients (accounting for 63 HSCTs) met the criteria for analysis. Fifty-six of these patients (57 HSCTs) underwent PT and/or OT while markedly thrombocytopenic. There was no correlation between platelet counts and intensities of rehabilitation interventions. There were no major bleeding events. There was no association between minor bleeding events and intensities of PT or OT interventions and no association between minor bleeding events and platelet counts. Only 5 minor bleeding events occurred during or after moderate or intensive therapy out of 346 PT and OT sessions (1.5%). CONCLUSIONS The results of our study suggest that bleeding complications during or after mobilization and supervised exercise during PT and OT in children with severe thrombocytopenia undergoing HSCT are minor and relatively rare. These are encouraging results for both patients and rehabilitation specialists treating this population who is at high risk of developing immobility-related complications.

Abstract
Chemotherapy is a leading intervention against cancer. Albeit highly effective, chemotherapy has a multitude of deleterious side-effects including skeletal muscle wasting and fatigue, which considerably reduces patient quality of life and survivability. As such, a defense against chemotherapy-induced skeletal muscle dysfunction is required. Here we investigate the effects of oxaliplatin (OXA) treatment in mice on the skeletal muscle and mitochondria, and the capacity for the Poly ADP-ribose polymerase (PARP) inhibitor, BGP-15, to ameliorate any pathological side-effects induced by OXA. To do so, we investigated the effects of 2 weeks of OXA (3 mg/kg) treatment with and without BGP-15 (15 mg/kg). OXA induced a 15% (p < 0.05) reduction in lean tissue mass without significant changes in food consumption or energy expenditure. OXA treatment also altered the muscle architecture, increasing collagen deposition, neutral lipid and Ca2+ accumulation; all of which were ameliorated with BGP-15 adjunct therapy. Here, we are the first to show that OXA penetrates the mitochondria, and, as a possible consequence of this, increases mtROS production. These data correspond with reduced diameter of isolated FDB fibers and shift in the fiber size distribution frequency of TA to the left. There was a tendency for reduction in intramuscular protein content, albeit apparently not via Murf1 (atrophy)- or p62 (autophagy)- dependent pathways. BGP-15 adjunct therapy protected against increased ROS production and improved mitochondrial viability 4-fold and preserved fiber diameter and number. Our study highlights BGP-15 as a potential adjunct therapy to address chemotherapy-induced skeletal muscle and mitochondrial pathology.

Abstract
BACKGROUND Treatment for acute lymphoblastic leukemia (ALL) can affect balance via different mechanisms, including sensory and motor peripheral neuropathy, cognitive impairment, and reduced muscle strength and flexibility. To provide an overview of what is currently known about the effects of cancer treatment on balance in pediatric ALL patients and survivors, and of the predictors of poor balance, a review of the literature was conducted. METHODS Five databases were searched for English-language original research articles on balance during or after treatment for pediatric ALL. RESULTS From a total of nine studies, six identified significant balance problems in children with ALL during or after treatment. The percentage of patients or survivors with impaired balance varied between 27% and 69% during treatment, 7% and 65% a few years after completion of treatment, and 14% and 17% many years after the completion of treatment. Factors associated with impaired balance were higher body mass index; higher intrathecal methotrexate dose; cranial radiation; knee extensor weakness; and impaired cognition. CONCLUSION Although heterogeneity between the studies regarding patient age; age at diagnosis; time since completion of treatment; and methods of quantifying balance make it difficult to reach a single conclusion, the evidence suggests that survivors may experience short- and/or long-term balance difficulties. While there is a need for additional studies to better understand the effects of impaired balance in survivors, clinicians treating both child and adult survivors of ALL need to be aware of these potential risks.

Abstract
This review aims to summarize the evidence for impairments of muscle strength and balance during and after treatment for childhood cancer. Thirty-two articles, identified in scientific databases by means of a structured search for investigations of muscle strength and balance in pediatric cancer patients and survivors, are evaluated. A summary of results is given with respect to matching reporting items to provide a qualitative analysis of the evidence. The majority of the studies reached a level 3 rating according to Oxford Centre for Evidence-Based Medicine (OCEBM) 2011 levels of evidence. Muscle strength and balance seem to be impaired in varying degrees depending on the diagnosis, treatment received, and time elapsed between treatment and evaluation. Drawing specific conclusions from the identified studies is difficult because of heterogeneous study samples and methods of research. Individual targeted exercise therapy programs during treatment and follow-up of childhood cancer could help to prevent and further diminish impairments of muscle strength and balance function among childhood cancer patients and survivors.

Abstract
PURPOSE/OBJECTIVES To examine associations among oxidative stress, fine and visual-motor abilities, and behavioral adjustment in children receiving chemotherapy for acute lymphoblastic leukemia (ALL)
. DESIGN A prospective, repeated-measures design
. SETTING Two pediatric oncology settings in the southwestern United States. SAMPLE 89 children with ALL were followed from diagnosis to the end of chemotherapy. METHODS Serial cerebrospinal fluid samples were collected during scheduled lumbar punctures and analyzed for oxidative stress biomarkers. Children completed fine motor dexterity, visual processing speed, and visual-motor integration measures at three time points. Parents completed child behavior ratings at the same times. MAIN RESEARCH VARIABLES Oxidative stress, fine motor dexterity, visual processing, visual-motor integration, and behavioral adjustment
. FINDINGS Children with ALL had below-average fine motor dexterity, visual processing speed, and visual-motor integration following the induction phase of ALL therapy. By end of therapy, visual processing speed normalized, and fine motor dexterity and visual-motor integration remained below average. Oxidative stress measures correlated with fine motor dexterity and visual-motor integration. Decreased motor functioning was associated with increased hyperactivity and anxiety
. CONCLUSIONS Oxidative stress occurs following chemo-therapy for childhood ALL and is related to impaired fine motor skills and visual symptoms
. IMPLICATIONS FOR NURSING Early intervention should be considered to prevent fine motor and visual-spatial deficits, as well as behavioral problems.

Abstract
Chemotherapy has been associated with increased mitochondrial reactive oxygen species production, mitochondrial dysfunction and skeletal muscle atrophy leading to severe patient clinical complications including skeletal muscle fatigue, insulin resistance and wasting. The exact mechanisms behind this skeletal muscle toxicity are largely unknown, and as such co-therapies to attenuate chemotherapy-induced side effects are lacking. Here, we review the current literature describing the clinical manifestations and molecular origins of chemotherapy-induced myopathy with a focus on the mitochondria as the target organelle via which chemotherapeutic agents establish toxicity. We explore the likely mechanisms through which myopathy is induced, using the anthracycline doxorubicin, and the platinum-based alkylating agent oxaliplatin, as examples. Finally, we recommend directions for future research and outline the potential significance of these proposed directions.

Abstract
OBJECTIVE Although more children are surviving critical illness, little is known about long-term physical impairment. This scoping review aims to critically appraise existing literature on functional outcome measurement tools, prevalence, and risk factors for physical impairments in pediatric critical care survivors. DATA SOURCES PubMed, Embase, and Cumulative Index to Nursing and Allied Health Literature, using a combination of MeSH terms and keywords (critical illness, intensive care, and functional outcomes/status). STUDY SELECTION All human studies reporting functional outcomes in children 0-18 years old admitted to the PICU. Non-English language, adult and preterm infant studies were excluded. DATA SYNTHESIS Three global assessment tools and eight multidimensional measures were used to measure functional outcome in pediatric survivors of critical illness. Rates of acquired functional impairment in a general pediatric intensive care cohort ranged from 10% to 36% at discharge and 10% to 13% after more than 2 years. Risk factors for acquired functional impairment include illness severity, the presence of organ dysfunction, length of ICU stay, and younger age. There is some evidence that physical impairment may be more severe and persistent than psychosocial components. CONCLUSIONS Functional impairment may be persistent in pediatric survivors of critical care. Unfortunately, studies varied largely in measurement timing and tools used. The lack of differentiation between impairment in different functional domains limited the generalizability of data. Further studies using a combination of standardized measures at various time points of the disease process can help establish more comprehensive rates of physical impairment.

Abstract
BACKGROUND A decreased physical fitness has been reported in patients and survivors of childhood cancer. This is influenced by the negative effects of the disease and the treatment of childhood cancer. Exercise training for adult cancer patients has frequently been reported to improve physical fitness. In recent years, literature on this subject has also become available for children and young adults with cancer, both during and after treatment. This is an update of the original review that was performed in 2011. OBJECTIVES To evaluate the effect of a physical exercise training intervention on the physical fitness (i.e. aerobic capacity, muscle strength, or functional performance) of children with cancer within the first five years from their diagnosis (performed either during or after cancer treatment), compared to a control group of children with cancer who did not receive an exercise intervention.To determine whether physical exercise within the first five years of diagnosis has an effect on fatigue, anxiety, depression, self efficacy, and HRQoL and to determine whether there are any adverse effects of the intervention. SEARCH METHODS We searched the electronic databases of Cochrane Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, and PEDro; ongoing trial registries and conference proceedings on 6 September 2011 and 11 November 2014. In addition, we performed a handsearch of reference lists. SELECTION CRITERIA The review included randomized controlled trials (RCTs) and clinical controlled trials (CCTs) that compared the effects of physical exercise training with no training, in people who were within the first five years of their diagnosis of childhood cancer. DATA COLLECTION AND ANALYSIS Two review authors independently identified studies meeting the inclusion criteria, performed the data extraction, and assessed the risk of bias using standardized forms. Study quality was rated by the Grading of Recommendation Assessment, Development and Evaluation (GRADE) criteria. MAIN RESULTS Apart from the five studies in the original review, this update included one additional RCT. In total, the analysis included 171 participants, all during treatment for childhood acute lymphoblastic leukaemia (ALL).The duration of the training sessions ranged from 15 to 60 minutes per session. Both the type of intervention and intervention period varied in all the included studies. However, the control group always received usual care.All studies had methodological limitations, such as small numbers of participants, unclear randomization methods, and single-blind study designs in case of one RCT and all results were of moderate to very low quality (GRADE).Cardiorespiratory fitness was evaluated by the 9-minute run-walk test, timed up-and-down stairs test, the timed up-and-go time test, and the 20-m shuttle run test. Data of the 9-minute run-walk test and the timed up-and-down stairs test could be pooled. The combined 9-minute run-walk test results showed significant differences between the intervention and the control groups, in favour of the intervention group (standardized mean difference (SMD) 0.69; 95% confidence interval (CI) 0.02 to 1.35). Pooled data from the timed up-and-down stairs test showed no significant differences in cardiorespiratory fitness (SMD -0.54; 95% CI -1.77 to 0.70). However, there was considerable heterogeneity (I(2) = 84%) between the two studies on this outcome. The other two single-study outcomes, 20-m shuttle run test and the timed up-and-go test, also showed positive results for cardiorespiratory fitness in favour of the intervention group.Only one study assessed the effect of exercise on bone mineral density (total body), showing a statistically significant positive intervention effect (SMD 1.07; 95% CI 0.48 to 1.66). The pooled data on body mass index showed no statistically significant end-score difference between the intervention and control group (SMD 0.59; 95% CI -0.23 to 1.41).Three studies assessed flexibility. Two studies assessed ankle dorsiflexion. One study assessed active ankle dorsiflexion, while the other assessed passive ankle dorsiflexion. There were no statistically significant differences between the intervention and control group with the active ankle dorsiflexion test; however, in favour of the intervention group, they were found for passive ankle dorsiflexion (SMD 0.69; 95% CI 0.12 to 1.25). The third study assessed body flexibility using the sit-and-reach distance test, but identified no statistically significant difference between the intervention and control group.Three studies assessed muscle strength (knee, ankle, back and leg, and inspiratory muscle strength). Only the back and leg strength combination score showed statistically significant differences on the muscle strength end-score between the intervention and control group (SMD 1.41; 95% CI 0.71 to 2.11).Apart from one sub-scale of the cancer scale (Worries; P value = 0.03), none of the health-related quality of life scales showed a significant difference between both study groups on the end-score. For the other outcomes of fatigue, level of daily activity, and adverse events (all assessed in one study), there were no statistically significant differences between the intervention and control group.None of the included studies evaluated activity energy expenditure, time spent on exercise, anxiety and depression, or self efficacy as an outcome. AUTHORS' CONCLUSIONS The effects of physical exercise training interventions for childhood cancer participants are not yet convincing. Possible reasons are the small numbers of participants and insufficient study designs, but it can also be that this type of intervention is not as effective as in adult cancer patients. However, the first results show some positive effects on physical fitness in the intervention group compared to the control group. There were positive intervention effects for body composition, flexibility, cardiorespiratory fitness, muscle strength, and health-related quality of life (cancer-related items). These were measured by some assessment methods, but not all. However, the quality of the evidence was low and these positive effects were not found for the other assessed outcomes, such as fatigue, level of daily activity, and adverse events. There is a need for more studies with comparable aims and interventions, using a higher number of participants that also include diagnoses other than ALL.

Abstract
Purpose This study assessed cardiorespiratory fitness (CRF), physical activity (PA), and sedentary behavior (SB), as well as factors associated with these outcomes in children during or shortly after cancer treatment. Methods Cross-sectionally, CRF data, obtained by the cardiopulmonary exercise test, and PA and SB data, obtained by an accelerometer, were assessed in children with cancer (8–18 years old). Linear regression models were used to determine associations between CRF, PA, or SB and patient characteristics. Results Among 60 children with cancer, mean age 12.6 years, 35 boys, 28 % were during cancer treatment. CRF, reported as the z score of VO2peak, showed that 32 children had a VO2peakz score which was −2 below the predicted value. CRF was significantly associated with PA and SB: each additional activity count per minute resulted in 0.05 ml/kg/min VO2peak increase and each additional minute sedentary reduced VO2peak by 0.06 ml/kg/min. Multiple linear regression models of PA and SB showed that decreased activity was significantly associated with higher age, being fatigued, being during childhood cancer treatment (p < 0.001), or having a higher percentage of fat mass. The multiple linear regression model showed that lower CRF was significantly associated with increased fatigue, being during cancer treatment, having a higher percentage of fat mass, and lower belief of own athletic competence (p < 0.001). Conclusion This study revealed that children during or shortly after cancer treatment have low CRF scores. The most inactive children had a higher fat mass, were fatigued, older, and during childhood cancer treatment. Unexpectedly, treatment-related factors showed no significant association with activity behavior.

Abstract
OBJECTIVE Although survival rates in childhood cancer have improved, prevention and reduction of late effects remain important. This study evaluates the effects of a combined physical exercise and psychosocial intervention on health-related quality of life (HrQoL) and psychosocial functioning in childhood cancer patients. METHODS In this multicenter randomized controlled trial, cancer patients (aged 8-18 years) and their parents filled in questionnaires on HrQoL, depressive symptoms, behavioral problems, and self-esteem. Measurements were conducted at baseline, shortly after the 12-week intervention period and 12 months after baseline. Generalized estimating equations analyses were performed to assess short-term and long-term psychosocial effects. RESULTS Of the 174 eligible patients, 68 (39.1%) participated. The intervention group consisted of 30 participants at baseline [mean age 13.0 (SD 3.0) years; 53% male], 26 at short-term and 22 at long-term follow-up. The 'care as usual' control group consisted of 38 participants at baseline [mean age 12.6 (SD 3.1) years; 53% male], 33 at short-term and 31 at long-term follow-up. Overall, the intervention did not improve psychosocial functioning and HrQoL. According to parent-proxy reports, the intervention leads to a greater improvement on pain-related HrQoL on both the short (β = 13.4; 95% CI: 3.0; 23.8) and long term (β = 13.0; 95% CI: 1.6; 24.4) and to greater improvement on procedural anxiety immediately after the intervention (β = 12.6; 95% CI: 1.9; 23.3). CONCLUSION A combined physical and psychosocial training for children with cancer did not have effects on HrQoL or psychosocial functioning, with exception of modest positive effects on parent-reported pain and procedural anxiety Copyright © 2015 John Wiley & Sons, Ltd.

Abstract
BACKGROUND Reduced motor performance can negatively affect physical activity and social partake after childhood cancer. Especially in bone tumor patients, who are at risk of physical limitations due to surgical interventions, motor performance has not yet been sufficiently investigated. Therefore, this study aimed at assessing motor performance in pediatric bone tumor patients. PROCEDURE Motor performance was measured within 2 years posttreatment using the MOON (test for MOtor performance in pediatric ONcology) test. This instrument enables quantitative data collection even in physically impaired patients for comparison with age-matched and sex-matched reference values. RESULTS Twenty-one patients (13 male) ages 15.2±2.1 years (median: 15 y, 10 to 19 y) and 9.4±7.4 months posttreatment (median: 6 mo, 2 to 24 mo) were tested. Motor performance was slightly reduced in muscular endurance of the legs; significantly reduced in speed, flexibility, eye-hand coordination, and muscular explosive strength (P<0.001), whereas patients' hand grip strength and static balance were superior to the reference values. Follow-up duration, body mass index, and tumor localization apparently affected motor performance. CONCLUSIONS These findings show serious reductions in motor performance within 2 years after bone tumor treatment and highlight the need for interventions to improve motor performance. The results should be used to advise and support patients to engage in suitable physical and sports activities.

Abstract
Cancer-related fatigue (CRF) is the most stressful and prevalent symptom in paediatric oncology patients. This integrative review aimed to identify, analyse and synthesise the evidence of non-pharmacological intervention studies to manage fatigue and psychological stress in a paediatric population with cancer. Eight electronic databases were used for the search: PubMed, Web of Science, CINAHL, LILACS, EMBASE, SCOPUS, PsycINFO and the Cochrane Library. Initially, 273 articles were found; after the exclusion of repeated articles, reading of the titles, abstracts and the full articles, a final sample of nine articles was obtained. The articles were grouped into five categories: physical exercise, healing touch, music therapy, therapeutic massage, nursing interventions and health education. Among the nine studies, six showed statistical significance regarding the fatigue and/or stress levels, showing that the use of the interventions led to symptoms decrease. The most frequently tested intervention was programmed physical exercises. It is suggested that these interventions are complementary to conventional treatment and that their use can indicate an improvement in CRF and psychological stress.

Abstract
UNLABELLED Reduced motor performance may particularly limit reintegration into normal life after cessation of treatment in pediatric cancer patients. This study aimed at analyzing motor performance at the end of the acute treatment phase and reveals potential risk factors for motor deficits. A childhood cancer population with different tumor entities was assessed with the MOON test, which allows for comparison with age- and gender-matched reference values of healthy children, at the end of the acute treatment phase. Forty-seven patients were tested at 7.0 ± 2.6 months after diagnosis. Significant reductions of motor performance affected muscular explosive strength (P < 0.001), handgrip strength (P < 0.001), muscular endurance of legs (P = 0.035), hand-eye coordination (P < 0.001), static balance (P = 0.003), speed (P = 0.012), and flexibility (P < 0.001). Loss of upper extremity coordination did not achieve statistical significance. Associations between single motor deficits and the tumor entity, age, body mass index, and inactivity during treatment were revealed, whereas no associations were found for gender and vincristine application. CONCLUSION Overall, motor performance was low in the patient group studied. We recommend that individualized exercise interventions to attenuate motor deficits and promote physical activity are needed during cancer treatment in order to enhance motor performance and improve social participation during and after cancer therapy.

Abstract
Children treated for cancer are at increased risk of developing chronic health conditions, some of which may manifest during or soon after treatment while others emerge many years after therapy. These health problems may limit physical performance and functional capacity, interfering with participation in work, social, and recreational activities. In this review, we discuss treatment-induced impairments in the endocrine, musculoskeletal, neurological, and cardiopulmonary systems and their influence on mobility and physical function. We found that cranial radiation at a young age was associated with broad range of chronic conditions including obesity, short stature, low bone mineral density and neuromotor impairments. Anthracyclines and chest radiation are associated with both short and long-term cardiotoxicity. Although numerous chronic conditions are documented among individuals treated for childhood cancer, the impact of these conditions on mobility and function are not well characterized, with most studies limited to survivors of acute lymphoblastic leukemia and brain tumors. Moving forward, further research assessing the impact of chronic conditions on participation in work and social activities is required. Moreover, interventions to prevent or ameliorate the loss of physical function among children treated for cancer are likely to become an important area of survivorship research.

Abstract
Young adult childhood cancer survivors are at an increased risk of frailty, a physiologic phenotype typically found among older adults. This phenotype is associated with new-onset chronic health conditions and mortality among both older adults and childhood cancer survivors. Mounting evidence suggests that poor fitness, muscular weakness, and cognitive decline are common among adults treated for childhood malignancies, and that risk factors for these outcomes are not limited to those treated with cranial radiation. Although the pathobiology of this phenotype is not known, early cellular senescence, sterile inflammation, and mitochondrial dysfunction in response to initial cancer or treatment-related insults are hypothesized to play a role. To the authors' knowledge, interventions to prevent or remediate frailty among childhood cancer survivors have not been tested to date. Pharmaceutical, nutraceutical, and lifestyle interventions have demonstrated some promise.

Abstract
BACKGROUND For a multi-center randomized trial investigating the effects of a 12-week physical and psychosocial intervention program for children with cancer, we invited 174 patients (8-18 years old) on treatment or within 1 year after treatment; about 40% participated. Reasons for non-participation were investigated. METHODS Eligible patients received written and verbal information about the study. Those declining to participate were asked to complete questionnaires concerning: reasons for non-participation, daily physical activity, health-related quality of life (HrQoL), and behavioral problems. Participants completed the same questionnaires at baseline (excluding 'reasons for non-participation'). RESULTS Of 174 eligible patients, 106 did not participate; of these, 61 (57.5%) completed the one-time survey. The main reasons for non-participation as reported by the parents were 'too time consuming' and 'participation is too demanding for my child', while children most frequently reported 'too time consuming' and 'already frequently engaged in sports'. No differences between participants and non-participants were found for age, HrQoL, parental-reported behavior problems, sport participation, school type, BMI, and perceived health. A greater distance from home to hospital resulted in reduced participation (β: -0.02; p = 0.01). Non-participants rated their fitness level higher (p = 0.03). Participating children (11-18 years old) reported more behavioral problems (p = 0.02), in particular internalizing problems (p = 0.06). CONCLUSIONS Participation of childhood cancer patients in an intensive physical and psychosocial intervention program seems related to the burden of the intervention and the travel distance from home to hospital. In general, non-participants rated their fitness level higher compared with participants. Patients with more (internalizing) behavioral problems seem more likely to participate in the study.

Abstract
AbstractPurposeKey advances in cancer treatment have led to an increasing number of long-term cancer survivors. Knowledge of the long-term effects of cancer treatment on leukaemia survivors is to some degree limited. This article investigates the effects of the treatment of childhood leukaemia on the quality of life (QOL), the physical and the psychological wellbeing and general development of survivors. This article reviews current literature to examine existing gaps in knowledge and identify a potential focus of future research and clinical practice.Materials and methodsOnline systematic searching, along with historical searching took place in order to retrieve relevant primary research papers for the review. Strict inclusion and exclusion criteria were applied to the literature, to create a manageable amount of research papers.ResultsThe extent of intellectual impairment among radiotherapy patients was significantly greater than those treated with chemotherapy only. Body composition, including endocrine function, is readily affected by cancer treatment. Early identification and interventions can greatly improve the QOL of survivors.ConclusionFurther research into the effect of treatment modality on the extent of chronic effects, along with investigations into the needs of the whole family unit, is required. Future practice must take into account long-term implications while ensuring effective holistic care.

Abstract
This study describes skeletal, neuromuscular and fitness impairments among 109 children (median age 10 [range 4-18] years, 65.1% male, 63.3% white) with acute lymphoblastic leukemia (ALL). Outcomes were measured 7-10 days after diagnosis and compared to age- and sex-specific expected values. Associations between function and health-related quality of life (HRQL) were evaluated with logistic regression. Children with ALL had sub-optimal bone mineral density (BMD) Z-score/height (mean ± standard error: - 0.53 ± 0.16 vs. 0.00 ± 0.14, p < 0.01), body mass index percentile (57.6 ± 3.15 vs. 50.0 ± 3.27%, p = 0.02), quadriceps strength (201.9 ± 8.3 vs. 236.1 ± 5.4 N, p < 0.01), 6 min walk distance (385.0 ± 13.1 vs. 628.2 ± 7.1 m, p < 0.001) and Bruininks-Oseretsky Test of Motor Proficiency scores (23 ± 2.5 vs. 50 ± 3.4%, p < 0.01). Quadriceps weakness was associated with a 20.9-fold (95% confidence interval 2.5-173.3) increase in poor physical HRQL. Children with newly diagnosed ALL have weakness and poor endurance and may benefit from early rehabilitation that includes strengthening and aerobic conditioning.

Abstract
BACKGROUND The purpose of this study was to evaluate the usefulness of a new gross motor skill test battery in acute lymphoblastic leukemia (ALL) children who have been off therapy for at least 1 year and to assess its discriminatory power (discriminant analysis) from healthy children. PROCEDURE Twenty children (10 males and 10 females) 9-11 years of age (median age = 10.6 years) were assessed by the UQAC-UQAM test battery and then compared to recent provincial norms. This pilot study was also an opportunity to validate this test battery as a reliable tool for clinical or research purposes in the area of chronic or disabling diseases in children. Eleven motor skill variables grouped into five factors have been measured (speed, agility, balance, coordination, and reaction time). RESULTS Scores from 10 of the 11 motor skill tests showed significant differences when compared to the control group (P ≤ 0.05). Nearly 50% of patients obtained an average score below the 15th percentile. Furthermore, stepwise discriminant analysis allowed classifying successfully 88.4% of children in the correct group (ALL or Control). The normal development of GMS among children affected by ALL appears to have been compromised. The UQAC-UQAM test battery seems to be sensitive enough to quantify with precision the extent of the motor impairment in these children. CONCLUSION The UQAC-UQAM test battery appears to be a useful tool to evaluate the extent to which ALL survivors are affected. Early motor intervention should be considered for those patients even during the treatment periods.

Abstract
BACKGROUND The risk for cardiovascular disease (CVD) is increased in long-term survivors of childhood acute lymphoblastic leukemia (ALL). Chemotherapy may have direct toxic effects on vascular endothelium, potentially increasing the significance of endothelial dysfunction in the development of CVD in ALL survivors. Endothelial structure and function can be measured with carotid intima media thickness (IMT) and brachial flow mediated dilation (FMD). IMT and FMD are intermediate markers of CVD. We studied endothelial function and the effects of an exercise program on vascular endothelium in long-term survivors of childhood ALL. PROCEDURE Twenty-one 16-30 year old long-term survivors of ALL (age at diagnosis ≤16 years) and 21 healthy controls were studied at baseline, and 17 of the ALL survivors participated in a 16 week home-based exercise program. IMT and FMD were studied before and after the exercise program. RESULTS At baseline, the ALL survivors had impaired overall FMD response (FMDauc, P = 0.02). FMDmax(%) was 22% lower (P = 0.06) and FMD at 40 seconds 44% lower (P = 0.01) compared to healthy controls. After the exercise program, FMD at 40 seconds (P < 0.01) and IMT (P = 0.02) improved. The mean overall FMD response increased by 25% after the exercise program, but this change was not statistically significant (P = 0.27). CONCLUSIONS Our results show that the excess burden of CVD morbidity in this population may possibly be alleviated by simple means. The importance of physical activity on the health of childhood ALL survivors should be emphasized. Longer, controlled studies are needed to confirm our findings.

Abstract
This systematic review evaluated empirical studies examining motor skills in children during and following treatment for acute lymphoblastic leukemia. Most studies indicated that children on-treatment display poorer gross and fine motor abilities than healthy peers, but generally have intact visual-motor integration skills. Studies have reported gross motor difficulties in 5-54% of survivors. There is some limited evidence for long-term fine motor deficits. The evidence for visual-motor integration difficulties in the survivor population is less consistent. Larger studies with a longitudinal design are needed to further specify the onset and timing of motor difficulties and ascertain risk factors.

Abstract
PURPOSE Childhood cancer survivors (CCSs) are at risk for physical disability. The aim of this investigation was to characterize and compare physical performance among CCSs and a group of siblings age < 18 years and determine if diagnosis, treatment, and physical activity levels were associated with lower performance scores. METHODS CCSs ≥ 5 years from diagnosis and a sibling comparison group were recruited and evaluated for strength, mobility, and fitness. Physical performance measures were compared in regression models between survivors and siblings by diagnosis and among survivors by treatment exposures and physical activity levels. RESULTS CCSs (n = 183; mean age ± standard deviation [SD], 13.5 ± 2.5 years; 53% male) scored lower than siblings (n = 147; mean age ± SD, 13.4 ± 2.4 years; 50% male) on lower-extremity strength testing, the timed up-and-go (TUG) test, and the 6-minute walk (6MW) test, despite reporting similar levels and types of habitual physical activity. The lowest scores were prevalent among survivors of CNS tumors and bone and soft tissue sarcomas on strength testing (score ± SD: CNS tumors, 76.5 ± 4.7; sarcoma 67.1 ± 7.2 v siblings, 87.3 ± 2.4 Newton-meters quadricep strength at 90° per second; P = .04 and .01, respectively) and among CNS tumor survivors on the TUG (score ± SD: 5.1 ± 0.1 v siblings, 4.4 ± 0.1 seconds; P < .001) and 6MW tests (score ± SD: 533.3 ± 15.6 v siblings, 594.1 ± 8.3 m; P < .001). CONCLUSION CCSs may have underlying physiologic deficits that interfere with function that cannot be completely overcome by participation in regular physical activity. These survivors may need referral for specialized exercise interventions in addition to usual counseling to remain physically active.

Abstract
Although survival rates in childhood cancer have distinctly improved, pediatric cancer patients often experience various disease- and treatment-related side effects with long-term consequences. Despite current studies investigating inactivity and limitations in physical functioning and quality of life in pediatric cancer patients, only little information regarding specific deficits in physical functioning and quality of life has been available until now. No study has yet analyzed these parameters from a global perspective and then identified specific deficits in a mixed childhood cancer population. Within this cross-sectional pilot study, motor performance and quality of life of 26 pediatric cancer patients were assessed after inpatient medical treatment, using standardized motor test batteries (MOT 4-6; DMT 6-18) and a quality of life questionnaire (KINDL®). Reference data have been mainly provided by the German "Children and Young People Health Survey" (KiGGS). Patients achieved lower motor performance scores (p = .000) (more than 27% below the average of healthy peers). Specific deficits were identified in motor speed and motor control (4-6 years), as well as in endurance, strength and coordination under time pressure (6-17 years). In terms of quality of life, no significant differences were examined compared to healthy children of the same age. The results of this study confirm that children with oncological diseases frequently have specific motor problems. Future research in pediatric oncology must investigate the impact of targeted, individualized exercise interventions addressing these specific deficits.

Abstract
Physical fitness is an essential feature of overall health. Our objective was to compare the physical performance between nontransplanted acute lymphoblastic leukemia (ALL) patients (study patients), healthy controls, and ALL patients after stem cell transplantation (SCT). Forty-five ALL patients (median age, 13.3 y) treated without cranial irradiation were compared with 34 ALL patients (12.0 y) treated with SCT and total body irradiation and 522 age-matched and sex-matched controls. Their physical performance was assessed by 6 muscle tests measuring speed and dynamic endurance, flexibility, acceleration, maximal speed, and speed differentiation. The patients were tested at a minimum of 3 years after treatment. The muscle test results of the study patients did not differ from that of the healthy controls. The study patients had normal body mass indexes (BMI). Only 42% of them exercised at least once a week. Those who exercised >3 times a week and those with a BMI below median had better results. SCT patients had inferior results in 4 out of 6 tests. The physical performance of nontransplanted ALL patients did not differ from that of healthy controls. A higher physical exercise activity and a BMI below median positively correlated with better muscle performance, supporting the importance of encouraging ALL survivors to exercise and avoid obesity.

Abstract
BACKGROUND A decreased physical fitness and impaired social functioning has been reported in patients and survivors of childhood cancer. This is influenced by the negative effects of disease and treatment of childhood cancer and by behavioural and social elements. Exercise training for adults during or after cancer therapy has frequently been reported to improve physical fitness and social functioning. More recently, literature on this subject became available for children and young adults with cancer, both during and after treatment. OBJECTIVES This review aimed to evaluate the effect of a physical exercise training intervention (at home, at a physical therapy centre, or hospital based) on the physical fitness of children with cancer, in comparison with the physical fitness in a care as usual control group. The intervention needed to be offered within the first five years from diagnosis.The second aim was to assess the effects of a physical exercise training intervention in this population on fatigue, anxiety, depression, self efficacy, and health-related quality of life and to assess the adverse effects of the intervention. SEARCH METHODS For this review the electronic databases of CENTRAL, MEDLINE, EMBASE, CINAHL, PEDro, and ongoing trial registries were searched on 6 September 2011. In addition, a handsearch of reference lists and conference proceedings was performed in that same month. SELECTION CRITERIA The review included randomised controlled trials (RCTs) and clinical controlled trials (CCTs) that compared the effects of physical exercise training with no training, in people who were within the first five years of their diagnosis of childhood cancer. DATA COLLECTION AND ANALYSIS By the use of standardised forms two review authors independently identified studies meeting the inclusion criteria, performed the data extraction, and assessed the risk of bias. Quality of the studies was rated by using the Grading of Recommendation Assessment, Development and Evaluation (GRADE) criteria. MAIN RESULTS Five articles were included in this review: four RCTs (14, 14, 28, and 51 participants) and one CCT (24 participants). In total 131 participants (74 boys, 54 girls, three unknown) were included in the analysis, all being treated for childhood acute lymphoblastic leukaemia (ALL). The study interventions were all implemented during chemotherapy treatment.The duration of the training sessions ranged from 15 to 60 minutes per session. Both the type of intervention, as well as the intervention period, which ranged from 10 weeks to two years, varied in all the included studies. In all included studies the control group received care as usual.All studies had methodological limitations, such as small numbers of participants, unclear randomisation methods, and single-blind study designs in case of an RCT.Cardiorespiratory fitness was studied by the use of the nine-minute run-walk test, the timed up-and-down stairs test, and the 20-m shuttle run test. Only the up-and-down stairs test showed significant differences between the intervention and the control group, in favour of the intervention group (P value = 0.05, no further information available).Bone mineral density was assessed in one study, in which a statistically significant difference in favour of the exercise group was identified (standardised mean difference (SMD) 1.07; 95% confidence interval (CI) 0.48 to 1.66; P value < 0.001). Body mass index was assessed in two studies. The pooled data on this item did not show a statistically significant difference between the intervention and control study group.Flexibility was assessed in three studies. In one study the active ankle dorsiflexion method was used to assess flexibility and the second study they used the passive ankle dorsiflexion test. No statistically significant difference between the intervention and control group was identified with the active ankle dorsiflexion test, whereas with the passive test method a statistically significant difference in favour of the exercise group was found (SMD 0.69; 95% CI 0.12 to 1.25; P value = 0.02). The third study assessed body flexibility by the use of the sit-and-reach distance test; no statistically significant difference between the intervention and control group was identified.One study assessed the effects of an inspiratory muscle training programme aimed to train the lung muscles and increase physical fitness. This study reported no significant effect on either inspiratory or expiratory muscle strength. Two other studies using either knee and ankle strength changes by hand-held dynamometry or the number of completed push-ups (with knees on the ground) and a peripheral quantitative computed tomography of the tibia to determine the muscle mass did not identify statistically significant differences in muscle strength/endurance.The level of daily activity, health-related quality of life, fatigue, and adverse events were assessed in one study only; for all these items no statistically significant differences between the intervention and control group were found.None of the included studies evaluated the outcomes activity energy expenditure, time spent exercising, anxiety and depression, or self efficacy. AUTHORS' CONCLUSIONS The effects of physical exercise training interventions for childhood cancer participants are not yet convincing due to small numbers of participants and insufficient study methodology. Despite that, first results show a trend towards an improved physical fitness in the intervention group compared to the control group. Changes in physical fitness were seen by improved body composition, flexibility, and cardiorespiratory fitness. However, the evidence is limited and these positive effects were not found for the other assessed outcomes, such as muscle strength/endurance, the level of daily activity, health-related quality of life, and fatigue. There is a need for more studies with comparable aims and interventions, using higher numbers of participants and for studies with another childhood cancer population than ALL only.

Front Pharmacol 2013; 4:49. [PMID: 23626576 PMCID: PMC3630332 DOI: 10.3389/fphar.2013.00049] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2012] [Accepted: 03/30/2013] [Indexed: 01/08/2023] Open
Abstract
There is evidence that survivors of childhood cancers, such as acute lymphoblastic leukemia (ALL), have increased rates of long-term skeletal muscle dysfunction. This places them at higher risk of physical restriction and functional impairment as well as potentially contributing to observed increases in cardiovascular disease and insulin resistance in later life. The mechanisms underlying these changes in skeletal muscle are unknown but chemotherapy drugs used in treatment for ALL are strongly implicated. Normal skeletal muscle growth, development, and function are dependent on correctly functioning muscle satellite cells, muscle motor neurons, and muscle mitochondria. Each of these key components is potentially susceptible to damage by chemotherapy in childhood, particularly prolonged courses including repeated administration of combination chemotherapy. If this chemotherapy-induced damage is not fully reversible, impairment of satellite cells, muscle motor innervation, and mitochondria could, either singly or together, lead to the emergence of delayed or persistent skeletal muscle dysfunction many years later. The known effects of individual drugs used in the treatment of ALL are outlined and the need for specific targeted studies to investigate the mechanisms underlying persistent muscle dysfunction in survivors of ALL and other childhood cancers is highlighted.
