Recommendations for surveillance of pulmonary dysfunction among childhood, adolescent, and young adult cancer survivors: a report from the International Late Effects of Childhood Cancer Guideline Harmonization Group.

Abstract
Childhood, adolescent, and young adult (CAYA) cancer survivors are at risk of pulmonary dysfunction. Current follow-up care guidelines are discordant. Therefore, the International Late Effects of Childhood Cancer Guideline Harmonization Group established and convened a panel of 33 experts to develop evidence-based surveillance guidelines. We critically reviewed available evidence regarding risk factors for pulmonary dysfunction, types of pulmonary function testing, and timings of surveillance, then we formulated our recommendations. We recommend that CAYA cancer survivors and healthcare providers are aware of reduced pulmonary function risks and pay vigilant attention to potential symptoms of pulmonary dysfunction, especially among survivors treated with allogeneic haematopoietic stem cell transplantation, thoracic radiotherapy, and thoracic surgery. Based on existing limited evidence and current lack of interventions, our panel recommends pulmonary function testing only for symptomatic survivors. Since scarce existing evidence informs our recommendation, we highlight the need for prospective collaborative studies to address pulmonary function knowledge gaps among CAYA cancer survivors.

Design and methods of a randomized telehealth-based intervention to improve fitness in survivors of childhood cancer with exercise intolerance. Contemp Clin Trials 2023; 133:107339. [PMID: 37730199 PMCID: PMC10591872 DOI: 10.1016/j.cct.2023.107339] [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: 05/05/2023] [Revised: 09/01/2023] [Accepted: 09/15/2023] [Indexed: 09/22/2023]
Abstract
BACKGROUND Exercise intolerance among childhood cancer survivors substantially increases risk for early mortality, reduced cognitive function, poor quality of life, emotional distress, and sub-optimal participation in social roles. Fortunately, exercise intolerance is modifiable, even among individuals with impaired cardiopulmonary and neuromuscular health. This study aims to evaluate the impact of tailored exercise intervention remotely supervised by fitness professionals in survivors with exercise intolerance. Telehealth-based delivery of the intervention aims to enhance uptake by removing the burden of travel and allowing participants to gain confidence with exercise and physical activity at home. METHODS This is an ongoing single-blind, two-arm, prospective, clinical trial that will randomize 160 participants 1:1 to intervention (n = 80) and attention control (n = 80) groups. The intervention group receives an individually tailored exercise prescription based on results from baseline assessments performed remotely via a Health Insurance Portability and Accountability Act-compliant virtual platform and personal preferences for aerobic exercise. Each prescription includes aerobic and strengthening components designed to progress gradually to 150-300-min of moderate aerobic activity and twice weekly strengthening exercises over 20-weeks. The first two weeks are supervised for 6 sessions, tapering to twice/week for weeks 3-4, once/week for weeks 5-8, every other week for weeks 9-16 and once midway between weeks 17-20. The schedule is modifiable depending on participant need, adherence, and response to exercise. Each session is approximately one hour. CONCLUSION This study tests the efficacy of an individually prescribed, virtually supervised exercise intervention on exercise intolerant childhood cancer survivors. CLINICALTRIALS gov registration: NCT04714840.

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.

The Impact of a Precision-Based Exercise Intervention in Childhood Hematological Malignancies Evaluated by an Adapted Yo-Yo Intermittent Recovery Test. Cancers (Basel) 2022; 14:cancers14051187. [PMID: 35267495 PMCID: PMC8909675 DOI: 10.3390/cancers14051187] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 02/21/2022] [Accepted: 02/23/2022] [Indexed: 01/27/2023] Open
Abstract
During cancer treatments in childhood hematological malignancies, reduced exercise tolerance is one of the main hardships. Precision-based training programs help children, adolescents, and young adults and their families to resume regular physical activity, exercise, and sports once they return to their communities after the intensive phases spent in hospital. This study was aimed at verifying whether an intermittent recovery test, the Yo-Yo AD, could provide a simple and valid way to evaluate an individual’s capacity to perform repeated intense exercise and to follow up on the impact of tailored exercise in children, adolescents, and young adults with hematological malignancies. The Yo-Yo AD involved the repetition of several shuttles to muscle exhaustion, at pre-established speeds (walking and slow running). The heart rate (HR) and oxygen saturation (SaO2) were monitored during the test. The total distance and the walking/running ability, measured as the slope of the HR vs. distance correlation, were investigated before (T0) and after 11 weeks (T1) of precision exercise intervention. The Yo-Yo AD was also performed by healthy children (CTRL). Ninety-seven patients (10.58 ± 4.5 years, 46% female) were enrolled. The Yo-Yo AD showed the positive impact of the exercise intervention by increasing the distance covered by the individuals (T0 = 946.6 ± 438.2 vs. T1 = 1352.3 ± 600.6 m, p < 0.001) with a more efficient walking/running ability (T0 = 2.17 ± 0.84 vs. T1 = 1.73 ± 0.89 slope, p < 0.0164). CTRLs performed better (1754.0 ± 444.0 m, p = 0.010). They were equally skillful (1.71 ± 0.27 slope) when compared to the patients after they received the precision-based intervention. No adverse events occurred during the Yo-Yo AD and it proved to be an accurate way of correctly depicting the changes in performance in childhood hematological malignancies.

Abstract
Simple Summary Childhood cancer survivors are at risk of developing important adverse effects, but there is growing evidence that physical exercise could help in this regard. The present review summarizes the history of pediatric exercise oncology and the main milestones achieved along the way. Overall, physical exercise appears to be safe and beneficial even during the most aggressive phases of pediatric cancer treatment and can represent an effective coadjuvant therapy for attenuating cancer-related adverse effects. Abstract Childhood cancer survivors are at risk of developing important adverse effects, many of which persist for years after the end of treatment. The implementation of interventions aiming at attenuating tumor/treatment-associated adverse effects is therefore a major issue in pediatric oncology, and there is growing evidence that physical exercise could help in this regard. The present review aims to summarize the main milestones achieved in pediatric exercise oncology. For this purpose, we conducted a systematic review of relevant studies written in English in the electronic database PubMed (from inception to 14 August 2021). This review traces the field of pediatric exercise oncology throughout recent history based on three fundamental pillars: (i) exercise during childhood cancer treatment; (ii) exercise during/after hematopoietic stem cell transplantation; and (iii) exercise after childhood cancer treatment. Accumulating evidence––although still preliminary in many cases––supports the safety and potential benefits of regular exercise (with no major contraindications in general) in the childhood cancer continuum, even during the most aggressive phases of treatment. Exercise can indeed represent an effective coadjuvant therapy for attenuating cancer-related adverse effects.

Does allogeneic stem cell transplantation in survivors of pediatric leukemia impact regular physical activity, pulmonary function, and exercise capacity? Mol Cell Pediatr 2021; 8:16. [PMID: 34738228 PMCID: PMC8569121 DOI: 10.1186/s40348-021-00127-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Accepted: 10/08/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Allogeneic hematopoietic stem cell transplantation (allo-HSCT) has improved survival in high-risk childhood leukemia but is associated with long-term sequelae such as impaired pulmonary function and reduced exercise capacity impacting quality of life. METHODS A convenience sample of 17 patients after allo-HSCT (HSCT-12 male, age 15.7±6.7 years, time after HSCT 5.3±2.8 years) underwent pulmonary function testing, echocardiography, and an incremental exercise test on a bike. Physical activity and health-related quality of life were assessed by questionnaires (7-day physical activity recall, PEDS-QL). Seventeen healthy age- and gender-matched controls served as control group (CG) for results of pulmonary function and exercise testing. RESULTS HSCT showed reduced pulmonary function (HSCT vs. CG: FEV1 90.5±14.0 vs. 108.0±8.7%pred; FVC 88.4±19.3 vs. 107.6±6.9%pred, DLCO 75.3±23.6 vs. 104.9±12.8%pred) and exercise capacity (VO2peak 89±30.8%pred, CG 98±17.5%pred; Wmax 84±21.7%pred, CG 115±22.8%pred), but no relevant cardiac dysfunction and a good quality of life (PEDS-QL mean overall score 83.3±10.7). Differences in peak oxygen uptake between groups were mostly explained by 5 adolescent patients who underwent total body irradiation for conditioning. They showed significantly reduced diffusion capacity and reduced peak oxygen uptake. Patients reported a mean time of inactivity of 777±159min/day, moderate activity of 110±107 min/day, hard activity of 35±36 min/day, and very hard activity of 23±22 min/day. A higher amount of inactivity was associated with a lower peak oxygen uptake (correlation coefficient tau -0.48, p=0.023). CONCLUSIONS This pilot study shows that although patients after allo-HSCT reported a good quality of life, regular physical activity and exercise capacity are reduced in survivors of stem cell transplantation, especially in adolescents who are treated with total body irradiation for conditioning. Factors hindering regular physical activity need to be identified and exercise counseling should be part of follow-up visits in these patients.

Abstract
Significance: Survivors of pediatric cancers have a high risk of developing side effects after the end of their treatments. Many potential factors have been associated with the onset of cardiometabolic disorders (CMD), including cancer disease itself, chemotherapy, hormonal treatment, radiotherapy, and genetics. However, the precise etiology and underlying mechanisms of these long-term complications are poorly understood. Recent Advances: Greater awareness is currently paid to the role of microbiota in the emergence of cancers and modulation of cancer therapies in both children and adults. Alterations in the composition and diversity of intestinal microbiota can clearly influence tumor development and progression as well as immune responses and clinical output. As dysbiosis is closely linked to the development of host metabolic diseases, including obesity, metabolic syndrome, type 2 diabetes, and non-alcoholic fatty liver disease, it may increase the risk of CMD in cancer populations. Critical Issues: Only limited studies targeting the profile of intestinal dysbiosis before and after cancer treatment have been conducted. Further, the exact contribution of intestinal dysbiosis to the development of CMD in cancer survivors is poorly appreciated. This review intends to clarify the influence of gut microbiota on CMD in childhood cancer survivors, elucidate the potential mechanisms, and evaluate the latest research on the interplay between diet/food supplement, microbiota, and cancer-related CMD. Future Directions: The implication of intestinal dysbiosis in late metabolic complications of childhood cancer survivors should be clarified. Intervention strategies could be developed to reduce the risk of survivors to CMD. Antioxid. Redox Signal. 34, 223-251.

Abstract
INTRODUCTION Childhood cancer survivors (CSs) might face an increased lifelong risk of lung function impairment. The lung clearance index (LCI) has been described as being more sensitive than spirometry in the early stages of some lung diseases. The aim of this study was to evaluate this index in a cohort of patients with a history of childhood cancer for the first time. MATERIALS AND METHODS We evaluated 57 off-treatment CSs aged 0-18 years old and 50 healthy controls (HCs). We used the multiple-breath washout method to study LCI and spirometry. RESULTS CSs did not show any differences from the controls in ventilation homogeneity (LCI 6.78 ± 1.35 vs. 6.32 ± 0.44; p: not significant [ns]) or lung function (FEV1 99.9 ± 11.3% vs. 103.0 ± 5.9% of predicted; p: ns; FVC 98.2 ± 10.3% vs. 101.1 ± 3.3% of predicted). LCI significantly correlated with the number of years since the last chemotherapy (r = .35, p < .05). CONCLUSIONS Our study describes the trend of LCI in a cohort of CSs and compares it with the results obtained from HCs. The results show that patients maintain both good values of respiratory function and good homogeneity of ventilation during childhood. Moreover, as LCI increases and worsens as the years pass after the end of the treatment could identify the tendency toward pulmonary fibrosis, which is typical of adult CSs, at an earlier time than spirometry.

Precision-based exercise as a new therapeutic option for children and adolescents with haematological malignancies. Sci Rep 2020; 10:12892. [PMID: 32733066 PMCID: PMC7393502 DOI: 10.1038/s41598-020-69393-1] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2020] [Accepted: 07/03/2020] [Indexed: 11/16/2022] Open
Abstract
Children and adolescents with haematological malignancies (PedHM) are characterized by a severe loss of exercise ability during cancer treatment, lasting throughout their lives once healed and impacting their social inclusion prospects. The investigation of the effect of a precision-based exercise program on the connections between systems of the body in PedHM patients is the new frontier in clinical exercise physiology. This study is aimed at evaluating the effects of 11 weeks (3 times weekly) of combined training (cardiorespiratory, resistance, balance and flexibility) on the exercise intolerance in PedHM patients. Two-hundred twenty-six PedHM patients were recruited (47% F). High or medium frequency participation (HAd and MAd) was considered when a participant joined; > 65% or between 30% and < 64% of training sessions, respectively. The “up and down stairs'' test (TUDS), “6 min walking” test (6MWT), the “5 Repetition Maximum strength” leg extension and arm lateral raise test (5RM-LE and 5RM-ALR), flexibility (stand and reach), and balance (stabilometry), were performed and evaluated before and after training. The TUDS, the 5RM-LE and 5RM-ALR, and the flexibility exercises showed an increase in HAd and MAd groups (P < 0.05), while the 6MWT and balance tests showed improvement only in HAd group (P < 0.0001). These results support the ever-growing theory that, in the case of the treatment of PedHM, ‘exercise is medicine’ and it has the potential to increase the patient’s chances of social inclusion.

Abstract
Objectives: Smartphone applications ("apps") can be used to promote health behavior change and expand the reach of behavioral interventions. To date, only a few existing apps have been developed for health promotion among adolescent survivors of childhood cancer. To address this gap, we developed an app-based intervention, using game design characteristics, theory-based behavioral strategies, and assistance from a health coach to motivate health behavior change for adolescent survivors of childhood cancer. This article describes the development and initial feasibility evaluation of the intervention. Methods: Using a theoretical framework and an extensive formative process, we developed an app-based game ("Mila Blooms") that promotes healthy eating and physical activity among adolescent survivors of childhood cancer. A single-arm 8-week intervention, using this app-based game, with assistance from a health coach, was conducted among a sample of pediatric cancer survivors (n = 15) to evaluate its initial feasibility for promoting health behavior change. Results: Results from the feasibility evaluation were encouraging. The majority of enrolled participants were retained throughout the 8-week intervention (93.8%). Participant satisfaction feedback indicated positive experiences, related to ease of use and enjoyment of the app. Although there was little evidence for behavior change attributable to the app in this first stage of development, there was a solid demonstration of the viability and appeal of the game features, and there were no adverse side effects. Conclusions: Results provide insights into how gamification can be used to promote health behaviors through an app-based intervention. Mila Blooms holds promise for promoting health behavior change. Lessons learned from our experiences could be useful for the future development and implementation of app-based adolescent health interventions.

Abstract
PURPOSE To estimate the prevalence of frailty among childhood cancer survivors and to determine the direct and indirect effects of treatment exposures, lifestyle factors, and severe, disabling, and life-threatening chronic condition on frailty. METHODS Childhood cancer survivors (≥ 5 years since diagnosis), treated between 1970 and 1999 when < 21 years old (n = 10,899; mean age, 37.6 ± 9.4 years; 48% male, 86% white) and siblings were included (n = 2,097; mean age, 42.9 ± 9.4 years). Frailty was defined as ≥ 3 of the following: low lean mass, exhaustion, low energy expenditure, walking limitations, and weakness. Generalized linear models were used to evaluate direct and indirect associations between frailty and treatment exposures, sociodemographic characteristics, lifestyle factors, and chronic condition. RESULTS The overall prevalence of frailty among survivors was 3 times higher compared with siblings (6.4%; 95% CI, 4.1% to 8.7%; v 2.2%; 95% CI, 1.2% to 3.2%). Survivors of CNS tumors (9.5%; 95% CI, 5.2% to 13.8%) and bone tumors (8.1%; 95% CI, 5.1% to 11.1%) had the highest prevalence of frailty. Survivors exposed to cranial radiation, pelvic radiation ≥ 34 Gy, abdominal radiation > 40 Gy, cisplatin ≥ 600 mg/m2, amputation, or lung surgery had increased risk for frailty. These associations were partially but not completely attenuated when sociodemographic characteristics, lifestyle factors, and chronic conditions were added to multivariable models. Cranial radiation (prevalence ratio [PR], 1.47; 95% CI, 1.20 to 1.76), pelvic radiation ≥ 34 Gy (PR, 1.46; 95% CI, 1.01 to 2.11), and lung surgery (PR, 1.75; 95% CI, 1.28 to 2.38) remained significant after sociodemographic, lifestyle, and chronic conditions were accounted for. CONCLUSION Childhood cancer survivors reported a higher prevalence of frailty compared with siblings. Radiation and lung surgery exposures were associated with increased risk for frailty. Interventions to prevent, delay onset, or remediate chronic disease and/or promote healthy lifestyle are needed to decrease the prevalence of frailty and preserve function in this at-risk population.

Abstract
BACKGROUND Respiratory viruses are a common cause of infection in immunosuppressed children undergoing cancer therapy. Pulmonary sequelae have been documented following respiratory viral infections (RVIs) in hematopoietic stem cell transplant (HSCT) recipients; however potential late effects in children undergoing nonmyeloablative chemotherapy have not been investigated. AIM To evaluate the long-term pulmonary morbidity of respiratory viral infections during chemotherapy in children with acute lymphoblastic leukemia (ALL). METHODS Childhood ALL survivors, aged 7 to 18 years, greater than 6 months posttreatment were recruited. Exclusion criteria included HSCT or proven bacterial/fungal respiratory infection during treatment. Subjects were classified into "viral" or "control" groups according to retrospective medical records that documented the presence of laboratory-proven RVIs during chemotherapy. Symptom questionnaires (Liverpool, ISAAC) and lung function testing (spirometry, plethysmography, diffusing capacity, forced oscillation technique to ATS/ERS standards) were then performed cross-sectionally at the time of recruitment. RESULTS Fifty-four patients (31 viral, 23 control) were recruited: median (range) age 11.2 (7.2-18.1) years, and at 4.9 (0.5-13) years posttherapy. Abnormalities were detected in 17 (31%) individuals (8 viral, 9 control), with the most common being DLCO impairment (3 viral, 4 control) and reduced respiratory reactance at 5 Hz (5 viral, 6 control). Children with RVIs during chemotherapy reported more current respiratory symptoms, particularly wheeze (odds ratio [OR], 3.0; 95% confidence interval [CI]: 0.9-10.0; P = .09) and cough (OR, 2.7; 95% CI: 0.8-9.5; P = .11). No differences in lung function tests were observed between the two groups. CONCLUSIONS Our study found children with RVIs during chemotherapy developed more long-term respiratory symptoms than controls; however, differences did not reach statistical significance. No differences in static lung function were found between the two groups. Overall, pulmonary abnormalities and/or significant ongoing respiratory symptoms were detected in nearly a third of ALL survivors treated without HSCT. Larger, prospective studies are warranted to evaluate the etiology and clinical significance of these findings.

Abstract
BACKGROUND An increase in survival rates of childhood cancer is associated with long-term health issues in survivors. METHODS We conducted a systematic review and meta-analysis comparing health status-related endpoints in childhood cancer survivors (CCS) versus controls. RESULTS Eighty-six studies (n = 98,480 participants, 62% CCS) were included in the review. Of these, 73 studies (n = 96,550, 63% CCS) could be meta-analyzed. CCS showed a lower left ventricular ejection and fractional shortening (SMD=-0.59 and -0.55, respectively, both p < 0.01 [n=1,824 and 1,880]), a lower HDL-cholesterol concentration (SMD=-0.48, p<0.001, n=1,378) and a higher waist-to-hip ratio (SMD=0.61, p < 0.01, n=229) than their healthy peers. No significant differences were found for the remaining endpoints. CONCLUSIONS CCS is associated with a lower left ventricular function and HDL-cholesterol level, and a higher waist-to-hip ratio than healthy controls. These findings support the need to closely monitor the cardiometabolic health status of CCS and to implement preventive lifestyle interventions for this population.

Abstract
Childhood leukaemia survivors (CLS) are known to have developed long-term impairment of lung function. The reasons for that complication are only partially known. The aims of this study were to assess pulmonary function in CLS and identify (1) risk factors and (2) clinical manifestations for the impairment of airflow and lung diffusion. The study group included 74 CLS: 46 treated with chemotherapy alone (HSCT−), 28 with chemotherapy and haematopoietic stem cell transplantation (HSCT+), and 84 healthy subjects (control group (CG)). Spirometry and diffusion limit of carbon monoxide (DLCO) tests were performed in all subjects. Ten (14%) survivors had restrictive, five (7%) had obstructive pattern, and 47 (66%) had reduced DLCO. The age at diagnosis, type of transplant, and type of conditioning regimen did not significantly affect the pulmonary function tests. The DLCO%pv were lower in CLS than in CG (p < 0.03) and in the HSCT+ than in the HSCT− survivors (p < 0.05). The pulmonary infection increased the risk of diffusion impairment (OR 5.1, CI 1.16–22.9, p = 0.019). DLCO was reduced in survivors who experienced CMV lung infection (p < 0.001). The main symptom of impaired lung diffusion was poor tolerance of exercise (p < 0.005). The lower lung diffusion capacity is the most frequent abnormality in CLS. HSCT and pulmonary infection, in particular with CMV infection, are strong risk factors for impairment of lung diffusion capacity in CLS. Clinical manifestation of DLCO impairment is poor exercise tolerance. A screening for respiratory abnormalities in CLS seems to be of significant importance.

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
INTRODUCTION One aim of the long-term care in survivors from acute lymphoblastic leukemia (ALL) during childhood is to avoid or limit complications caused by aggressive therapeutic strategies. AREAS COVERED ALL survivors are a heterogeneous group according to therapeutic protocols. In the last decades, cranial radiotherapy (cRT) has been largely replaced by intrathecal chemotherapy (CT) with a reduction of endocrine sequelae. Published studies are generally difficult to be interpreted because patients were treated according to different risk-adapted protocols and results are conflicting. We perform this review on endocrine long-term effects in childhood ALL survivors focusing on studies published in the last decades. Articles were selected using the following terms (Mesh terms): 'acute lymphoblastic leukemia' AND 'survivors' AND 'childhood' AND 'growth/puberty/fertility/obesity/metabolic syndrome/bone'. EXPERT COMMENTARY Most childhood ALL survivors treated with CT alone attain normal height and have adequate pubertal development. Despite recent protocols improvements, ALL survivors still develop long-term metabolic complications (overweight, obesity, and cardiovascular disease) especially the female gender and patients with an increased body mass index (BMI) at diagnosis. The aim of this review is to describe the state of the art on these topics. We should be able to anticipate, prevent, and treat endocrine long-term morbidities through a well-established follow-up strategy.

Abstract
BACKGROUND Survivors of childhood acute lymphoblastic leukemia (ALL) are at risk of late treatment-related side-effects. Data regarding prevalence and risk factors for impairments in pulmonary function and cardiorespiratory fitness are limited, and reported findings are inconsistent and inconclusive. MATERIAL AND METHODS In a cross-sectional study, 116 ALL survivors (median 5 years at diagnosis, 29 years at follow-up, 53% females) were examined, median 23 years after treatment with chemotherapy only. Individual cumulative doses of cytostatic agents were calculated. Methods included blood tests, echocardiography, pulmonary function tests and cardiorespiratory exercise test. RESULTS Females had lower % predicted gas diffusing capacity (DLCO) than males (mean [SD] 84 [13] versus 97 [14], p < .001). Impairment in DLCO was found in 34% females versus 7% males, p < .001. In a multiple linear regression model, female gender, body mass index (BMI) and smoking were risk factors for reduced % predicted DLCO, with a borderline significant effect of left ventricular ejection fraction (LVEF). Impaired cardiorespiratory fitness was found in 42% of the survivors, with a borderline increased risk in females, p = .06. Smoking and BMI were risk factors for reduced % predicted VO2peak. Subjects exposed to anthracyclines had lower LVEF% and % predicted VO2peak than those not exposed, (mean [SD] 56.2 [4.3] versus 59.2 [5.2], p = .01 and 86.9 [18.4] versus 92.8 [18.4], p = .03, respectively). CONCLUSIONS Impairments in pulmonary function and cardiorespiratory fitness are common in very long-term survivors of childhood ALL. Risk factors are female gender, BMI and smoking. In order to preserve pulmonary function and cardiorespiratory fitness, we suggest increased attention and targeted advice on modifiable lifestyle factors such as smoking, inactivity and overweight.

Abstract
A symptom-limited incremental cycle ergometer test was performed in 17 young adult patients treated with hematopoietic cell transplantation and total body irradiation for hematologic malignancies during childhood. These 17 young adult patients were compared with 17 sex- and age-matched healthy control subjects. Assessments of pulmonary function, cardiac function, body composition, and levels of growth hormone were made. The median follow-up was 17.7 years. Patients achieved 63.2% of the predicted peak workload, whereas controls achieved 96.1% (P < .001). All patients, but only 1 control, failed to achieve a peak workload >80% (P < .001). Fat-free mass was significantly lower (43.5 vs 57.6 kg, P < .001) and fat mass percentage was significantly higher (31.8% vs 24.2%, P = .011) in the patients. The peak workload adjusted for fat-free mass was significantly lower in the patients (3.3 vs 4.3, P < .001). In the patients, peak workload correlated significantly with total lung capacity (r = .54, P = .025). In summary, long-term survivors have significantly decreased exercise capacity compared with healthy individuals. Together with their altered body composition, this may predispose them to cardiovascular disease.

Abstract
Hematopoietic stem cell transplantation is a therapeutic strategy for several oncohematological diseases. It increases survival rates but leads to a high incidence of related effects. The objective of this paper was to examine the existing literature on physical exercise interventions among pediatric HSCT recipients to explore the most often utilized rehabilitative assessment and treatment tools. Studies published from 2002 to April 1, 2015 were selected: 10 studies were included. A previous literary review has shown that rehabilitation programs have a positive impact on quality of life. Our analysis identified some significant outcome variables and shared intervention areas.

Abstract
BACKGROUND Pulmonary complications after cancer therapy are varied. This study describes pulmonary outcomes among childhood cancer survivors and evaluates their impact on daily activities. METHODS The incidence of pulmonary outcomes (asthma, chronic cough, emphysema, lung fibrosis, oxygen need, and recurrent pneumonia) reported among 5-year cancer survivors (n = 14,316) and the incidence of death due to pulmonary causes among all eligible survivors (n = 20,690) in the Childhood Cancer Survivor Study were compared with those for sibling controls (n = 4027) with cumulative incidence, standardized mortality ratio (SMR), and piecewise exponential models. Logistic regression with random effects was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for activity limitations with pulmonary complications. RESULTS By the age of 45 years, the cumulative incidence of any pulmonary condition was 29.6% (95% CI, 29.1%-30.0%) for cancer survivors and 26.5% (95% CI, 24.9%-28.0%) for siblings. Fewer survivors reported ever smoking (23.6% vs 36.4%, P < .001), but survivors were more likely to report chronic cough (rate ratio [RR], 1.6; 95% CI, 1.4-1.9), oxygen need (RR, 1.8; 95% CI, 1.5-2.2), lung fibrosis (RR, 3.5; 95% CI, 2.3-5.4), and recurrent pneumonia (RR, 2.0; 95% CI, 1.4-3.0). The SMR for death due to pulmonary causes was 5.9 (95% CI, 4.2-8.1), and it was associated with platinum exposure and lung radiation (P < .01). The impact of chronic cough on daily activities for survivors (OR vs survivors without chronic cough, 2.7) was greater than that for siblings (OR, 2.0; P = .04). CONCLUSIONS Pulmonary complications are substantial among adult survivors of childhood cancer and can affect daily activities. Cancer 2016;122:3687-96. © 2016 American Cancer Society.

Abstract
BACKGROUND Symptoms of pulmonary injury following lung irradiation may not manifest clinically in childhood. We performed comprehensive pulmonary evaluation of patients who had received lung irradiation for treatment of cancer. MATERIALS AND METHODS Patients underwent a focused history and physical examination, computed tomography of the chest, pulmonary function test, and cardiopulmonary exercise stress test (CPET). Health-related Quality of Life was also measured. RESULTS Fourteen patients were recruited with median age of 16 years (range, 6 to 21 y). Median time from pulmonary radiation to testing was 5 years (range, 2 to 11 y). Five patients reported pulmonary symptoms. Twelve patients (85.7%) had at least 1 pulmonary function test abnormality. Nine patients demonstrated CPET abnormalities; 7 patients had abnormal pulmonary limitation to exercise, and 5 patients had exercise-induced bronchospasm. The pulmonary limitations included abnormal ventilatory response to exercise in 5 patients, and gas exchange abnormalities in 4 patients. Chest computed tomography demonstrated grade 1-2 radiation-induced lung changes in 4 patients, and grade 3 abnormalities in 1 patient. CONCLUSIONS Significant pulmonary dysfunction was observed in childhood cancer survivors who had received lung irradiation. CPET is feasible in childhood cancer survivors and can be valuable for assessment of pulmonary function and exercise capacity.

Abstract
PURPOSE This study was undertaken to determine the magnitude of pulmonary dysfunction in childhood cancer survivors when compared with healthy controls and the extent (and predictors) of decline over time. PATIENTS AND METHODS Survivors underwent baseline (t1) pulmonary function tests, followed by a second comprehensive evaluation (t2) after a median of 5 years (range, 1.0 to 10.3 years). Survivors were also compared with age- and sex-matched healthy controls at t2. RESULTS Median age at cancer diagnosis was 16.5 years (range, 0.2 to 21.9 years), and time from diagnosis to t2 was 17.1 years (range, 6.3 to 40.1 years). Compared with odds for healthy controls, the odds of restrictive defects were increased 6.5-fold (odds ratio [OR], 6.5; 95% CI, 1.5 to 28.4; P < .01), and the odds of diffusion abnormalities were increased 5.2-fold (OR, 5.2; 95% CI, 1.8 to 15.5; P < .01). Among survivors, age younger than 16 years at diagnosis (OR, 3.0; 95% CI, 1.2 to 7.8; P = .02) and exposure to more than 20 Gy chest radiation (OR, 5.6; 95% CI, 1.5 to 21.0; P = .02, referent, no chest radiation) were associated with restrictive defects. Female sex (OR, 3.9; 95% CI, 1.7 to 9.5; P < .01) and chest radiation dose (referent: no chest radiation; ≤ 20 Gy: OR, 6.4; 95% CI, 1.7 to 24.4; P < .01; > 20 Gy: OR, 11.3; 95% CI, 2.6 to 49.5; P < .01) were associated with diffusion abnormalities. Among survivors with normal pulmonary function tests at t1, females and survivors treated with more than 20 Gy chest radiation demonstrated decline in diffusion function over time. CONCLUSION Childhood cancer survivors exposed to pulmonary-toxic therapy are significantly more likely to have restrictive and diffusion defects when compared with healthy controls. Diffusion capacity declines with time after exposure to pulmonary-toxic therapy, particularly among females and survivors treated with high-dose chest radiation. These individuals could benefit from subsequent monitoring.

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
In the USA, approximately 26,000 adolescents and young adults (AYAs) aged 15-29 years are diagnosed with cancer every year. The cure rate among this population exceeds 80%, resulting in a growing number of AYA cancer survivors. AYA cancer survivors suffer from a wide range of long-term treatment-related toxicities that adversely affect quality of life and increase the risk of premature death. Therefore, it is important to recognize the unique medical needs of the AYA cancer survivors and develop a cost-effective and systemic approach to screen and prevent cancer treatment-related sequelae and the adverse health outcomes.

Abstract
BACKGROUND Separating out the effects of cancer and treatment between central and peripheral components of the O2 delivery chain should be of interest to clinicians for longitudinal evaluation of potential functional impairment in order to set appropriate individually tailored training/rehabilitation programmes. We propose a non-invasive method (NIRS, near infrared spectroscopy) to be used in routine clinical practice to evaluate a potential impairment of skeletal muscle oxidative capacity during exercise in children previously diagnosed with acute lymphoblastic leukaemia (ALL). The purpose of this study was to evaluate the capacity of skeletal muscle to extract O2 in 10 children diagnosed with ALL, 1 year after the end of malignancy treatment, compared to a control group matched for gender and age (mean±SD = 7.8±1.5 and 7.3±1.4 years, respectively). METHODS AND FINDINGS Participants underwent an incremental exercise test on a treadmill until exhaustion. Oxygen uptake ([Formula: see text]), heart rate (HR), and tissue oxygenation status (Δ[HHb]) of the vastus lateralis muscle evaluated by NIRS, were measured. The results showed that, in children with ALL, a significant linear regression was found by plotting [Formula: see text] vs Δ[HHb] both measured at peak of exercise. In children with ALL, the slope of the HR vs [Formula: see text] linear response (during sub-maximal and peak work rates) was negatively correlated with the peak value of Δ[HHb]. CONCLUSIONS The present study proves that the NIRS technique allows us to identify large inter-individual differences in levels of impairment in muscle O2 extraction in children with ALL. The outcome of these findings is variable and may reflect either muscle atrophy due to lack of use or, in the most severe cases, an undiagnosed myopathy.

Abstract
The aim of this study was to assess the fitness levels and possible deficits in physical performance in children with a diagnosis of childhood acute leukemia and lymphoma after 10 months of therapy ending through a specific test battery. A total of 58 subjects were enrolled in this study. The experimental group (EG) (7.55 ± 2.43 years; 41.8 ± 16.37 kg; 144.6 ± 10.21 cm) consisted of 18 children with diagnosed leukemia and lymphoma after completion of 10 months of therapy intervention and 40 healthy children who were enrolled in a control group (CG) (7.92 ± 1.78 years; 37.4 ± 12.37 kg; 140.6 ± 12.61 cm). A testing battery including the standing broad jump; the sit-up test; the 4 × 10 m shuttle run test, and the hand grip strength test were administered to both groups. An unpaired t-test was adopted to determine differences and the Pearson product moment was administered when appropriate. Results of the EG were generally lower when compared to the CG. Significant differences were identified for the standing broad jump (P < 0.05); 4 × 10 m shuttle run (P < 0.05); hand grip test DX (P < 0.05), and hand grip test SX (P < 0.05). No significant differences were found between the sit-up tests. Pearson product moment correlation revealed a good interaction for all EG participants. Findings suggest that the proposed testing battery could be an appropriate tool to evaluate residual fitness levels in children with previous hematological malignancies. However, our results have to be confirmed with a larger number of participants with the same diagnosis of our EG.

Reduced cardiorespiratory fitness in adult survivors of childhood acute lymphoblastic leukemia. Pediatr Blood Cancer 2013; 60:1358-64. [PMID: 23418044 PMCID: PMC3725590 DOI: 10.1002/pbc.24492] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2012] [Accepted: 01/09/2013] [Indexed: 11/05/2022]
Abstract
BACKGROUND Adult survivors of childhood acute lymphoblastic leukemia (ALL) are at increased cardiovascular risk. Studies of factors including treatment exposures that may modify risk of low cardiorespiratory fitness in this population have been limited. PROCEDURE To assess cardiorespiratory fitness, maximal oxygen uptake (VO2 max) was measured in 115 ALL survivors (median age, 23.5 years; range 18-37). We compared VO2 max measurements for ALL survivors to those estimated from submaximal testing in a frequency-matched (age, gender, race/ethnicity) 2003-2004 National Health and Nutritional Examination Survey (NHANES) cohort. Multivariable linear regression models were constructed to evaluate the association between therapeutic exposures and outcomes of interest. RESULTS Compared to NHANES participants, ALL survivors had a substantially lower VO2 max (mean 30.7 vs. 39.9 ml/kg/min; adjusted P < 0.0001). For any given percent total body fat, ALL survivors had an 8.9 ml/kg/min lower VO2 max than NHANES participants. For key treatment exposure groups (cranial radiotherapy [CRT], anthracycline chemotherapy, or neither), ALL survivors had substantially lower VO2 max compared with NHANES participants (all comparisons, P < 0.001). Almost two-thirds (66.7%) of ALL survivors were classified as low cardiorespiratory fitness compared with 26.3% of NHANES participants (adjusted P < 0.0001). In multivariable models including only ALL survivors, treatment exposures were modestly associated with VO2 max. Among females, CRT was associated with low VO2 max (P = 0.02), but anthracycline exposure was not (P = 0.58). In contrast, among males, anthracycline exposure ≥ 100 mg/m(2) was associated with low VO2 max (P = 0.03), but CRT was not (P = 0.54). CONCLUSION Adult survivors of childhood ALL have substantially lower levels of cardiorespiratory fitness compared with a similarly aged non-cancer population.

Abstract
BACKGROUND Impaired motor performance and reduced maximum exercise capacity during and after treatment of acute lymphoblastic leukemia (ALL) has been shown. However, no longitudinal study monitoring motor performance after cessation of treatment has been published. Whether sub-maximal exercise capacity is reduced is unknown. PROCEDURE Motor performance of pediatric ALL survivors, treated with Dutch Childhood Oncology Group ALL-9 protocol was measured with the movement-ABC at stop treatment and ≥5 years later. At follow-up functional exercise capacity was also investigated using the 6-minute walk test (6MWT). Heart rate and oxygen saturation were measured with a portable pulse oximeter before and after the 6MWT. RESULTS Nineteen boys and 15 girls, median age 12.3 years (range: 9.0-18.7), median time since completion of chemotherapy 5.2 years (5.0-7.1), participated. Mean height/age and weight/age were within the norm, whereas mean BMI/age was significantly increased (mean SDS 0.38, SEM 0.17, P = 0.04). Motor performance had improved significantly (P = 0.001). In contrast, functional exercise capacity at follow-up was significantly impaired (mean SDS -2.05, SEM 0.13, P < 0.001). CONCLUSIONS At ≥5 years after completion of ALL treatment motor performance had improved significantly, but functional exercise capacity was significantly impaired. The exact underlying cause of this late effect needs further study.

Abstract
Acute lymphoblastic leukemia is the most common malignancy in childhood. Continuous progress in risk-adapted treatment for childhood acute lymphoblastic leukemia has secured 5-year event-free survival rates of approximately 80% and 8-year survival rates approaching 90%. Almost 75% of survivors, however, have a chronic health condition negatively impacting on cardiovascular morbidity and mortality. Obesity can be considered one of the most important health chronic conditions in the general population, with an increasing incidence in patients treated for childhood cancers and especially in acute lymphoblastic leukemia survivors who are, at the same time, more at risk of experiencing precocious cardiovascular and metabolic co-morbidities. The hypothalamic-pituitary axis damage secondary to cancer therapies (cranial irradiation and chemotherapy) or to primary tumor together with lifestyle modifications and genetic factors could affect long-term outcomes. Nevertheless, the etiology of obesity in acute lymphoblastic leukemia is not yet fully understood. The present review has the aim of summarizing the published data and examining the most accepted mechanisms and main predisposing factors related to weight gain in this particular population.

Abstract
The purpose of this review is to summarize literature that describes the impact of exercise on health and physical function among children during and after treatment for cancer. Relevant studies were identified by entering the following search terms into Pubmed: aerobic training; resistance training; stretching; pediatric; children; AND cancer. Reference lists in retrieved manuscripts were also reviewed to identify additional trials. We include fifteen intervention trials published between 1993 and 2011 that included children younger than age 21 years with cancer diagnoses. Nine included children with an acute lymphoblastic leukemia (ALL) diagnosis, and six children with mixed cancer diagnoses. Generally, interventions tested were either in-hospital supervised exercise training or home based programs designed to promote physical activity. Early evidence from small studies indicates that the effects of exercise include increased cardiopulmonary fitness, improved muscle strength and flexibility, reduced fatigue and improved physical function. Generalizations to the entire childhood cancer and childhood cancer survivor populations are difficult as most of the work has been done in children during treatment for and among survivors of ALL. Additional randomized studies are needed to confirm these benefits in larger populations of children with ALL, and in populations with cancer diagnoses other than ALL.

Abstract
BACKGROUND The purpose of this article is to summarize the literature that documents the long-term impact of cancer treatment modalities on pulmonary function among survivors of cancer and to identify potential areas for further research. METHODS Systematic reviews of clinical trials, observational studies, case series, and review articles were conducted. Articles were limited to the studies that discussed pulmonary toxicity or late effects among pediatric cancer survivors and to follow-up investigations that were conducted a minimum of 2 years after completion of cancer-related treatment or 1 year after hematopoietic stem cell transplant. RESULTS Sixty publications (51 clinical studies/reports and nine reviews) published from January 1970 to June 2010 in PubMed met the inclusion criteria. Data showed an association between radiotherapy, alkylating agents, bleomycin, hematopoietic stem cell transplant, and thoracic surgery and pulmonary toxicity, as well as possible interactions among these modalities. CONCLUSIONS Pulmonary toxicity is a common long-term complication of exposure to certain anticancer therapies in childhood and can vary from subclinical to life threatening. Pulmonary function and associated loss of optimal exercise capacity may have adverse effects on long-term quality of life in survivors. Lung function diminishes as a function of normal aging, and the effects of early lung injury from cancer therapy may compound these changes. The information presented in this review is designed to provide a stimulus to promote both observational and interventional research that expands our knowledge and aids in the design of interventions to prevent or ameliorate pulmonary late effects among survivors of childhood cancer.

Abstract
In the present study the authors evaluated therapy-related long-term adverse effects and physical activity in a cohort of long-term survivors of childhood acute lymphoblastic leukemia (ALL), diagnosed in their center between March 1991 and August 2000, treated according to the AIEOP (Associazione Italiana di Ematologia e Oncologia Pediatrica) ALL 91 or 95 study protocol and regularly seen in the authors' long-term follow-up unit. The authors analyzed the long-term sequelae of major body systems in this cohort of subjects and administered an "ad hoc" questionnaire concerning sport. The authors found that 70 patients out of 102 (68.5%) showed no late effects, 10% presented only instrumental or neuropsychological test abnormalities, and 21.5% had 1 or more clinical late sequelae. None of the evidenced late effects represented a contraindication to do physical activity. Sixty-one percent of survivors do physical activity, most of them regularly. Sixty-one percent of males and 18.5% of females (P < .005) do competitive sport (sports rates are similar to those of the general age-matched population). Nearly all subjects spontaneously choose to do sport and think physical exercise is an important and useful resource for their health. The authors conclude that the more recent therapy regimens for leukemia treatment, excluding bone marrow transplantation, do not seem to cause such late effects as to prevent survivors from doing sport. Therefore, in the care of ALL survivors, physical activity is not only not contraindicated, but should also be promoted as much as possible. The development of specific educational programs is warranted as part of the care of cancer survivors.

Abstract
Children treated for cancer face the risk of complications later in life, including pulmonary dysfunction. The objective of this study was to evaluate frequency and severity of pulmonary complications in survivors of childhood leukemia and lymphoma treated with chemotherapy alone or combined with radiotherapy. Seventy cancer survivors of hematological malignancies were evaluated for pulmonary complications through history taking, chest examination, high-resolution computed tomography (HRCT) chest, and pulmonary function testing (PFTs). Although most survivors were not clinically compromised, the spectrum of impaired PFTs included obstructive pattern (14.3%), restrictive pattern (5.7%), and mixed pattern (20%). Significant pulmonary dysfunction was seen in children older than 10 years of age (P = .003), and in patients treated with combined chemotherapy and radiotherapy (72.7%) compared with those treated with chemotherapy alone (25%) (P = .001). Cumulative dose of bleomycin was significantly associated with abnormal PFTs (P = .04). Multivariate analysis revealed methotrexate therapy as significant predictor of abnormal PFTs (P = .002). Male patients who received combined therapy showed higher frequency of restrictive, obstructive lung disease, abnormal respiratory reactance, and peripheral airway disease (P = .007, P = .04, P = .002, P = .003, P = .05, respectively). Those with abnormal CT findings (n = 14) had lower forced vital capacity (FVC%), forced expiratory volume in 1 second (FEV(1)%), and peak expiratory flow (PEF%) when compared to cases with normal CT (P = .001, P < 0.001, P = .001, respectively). Subclinical pulmonary function abnormalities are found in survivors of childhood hematological malignancies previously treated and off therapy. Pulmonary dysfunction is more evident with combined chemotherapy and radiotherapy, bleomycin, and methotrexate are the most incriminated chemotherapeutic agents, and males are at higher risk than females; therefore a specific and extended follow-up is warranted.

Abstract
Owing to improved treatment pro-tocols in the last 25 years there have been dramatic improvements in the 5-year relative survival rate of the most prevalent childhood cancers. For instance, the 5-year relative survival rate among children for all cancer sites combined, improved from 58% to 80% in patients diagnosed in 1975-1977 and in 1996-2004 respectively. However, as survival rates have improved, there has been an increasing recognition of adverse short and longer term effects associated with treatment and cancer itself, which we describe in detail in this chapter. There is growing interest in those interventions that can counteract the adverse effects of treatment and cancer. Because such adverse effects are further aggravated by physical inactivity, a special emphasis is being placed on physical activity (PA) interventions. Results are promising: there is increasing evidence that regular PA can improve the overall health status, functional capacity, and quality of life (QOL) of children with cancer as well as of older survivors of childhood cancer.

Abstract
BACKGROUND Young adult survivors of childhood brain tumors (BTs) may have late effects that compromise physical performance and everyday task participation. The objective of this study was to evaluate muscle strength, fitness, physical performance, and task participation among adult survivors of childhood BTs. METHODS In-home evaluations and interviews were conducted for 156 participants (54% men). Results on measures of muscle strength, fitness, physical performance, and participation were compared between BT survivors and members of a population-based comparison group by using chi-square statistics and 2-sample t tests. Associations between late effects and physical performance and between physical performance and participation were evaluated in regression models. RESULTS : The median age of BT survivors was 22 years (range, 18-58 years) at the time of the current evaluation, and they had survived for a median of 14.7 years (range, 6.5-45.9 years) postdiagnosis. Survivors had lower estimates of grip strength (women, 24.7 + or - 9.2 kg vs 31.5 + or - 5.8 kg; men, 39.0 + or - 12.2 kg vs 53.0 + or - 10.1 kg), knee extension strength (women, 246.6 + or - 95.5 Newtons [N] vs 331.5 + or - 5.8 N; men, 304.7 + or - 116.4 N vs 466.6 + or - 92.1 N), and peak oxygen uptake (women, 25.1 + or - 8.8 mL/kg per minute vs 31.3 + or - 5.1 mL/kg per minute; men, 24.6 + or - 9.5 mL/kg per minute vs 33.2 + or - 3.4 mL/kg per minute) than members of the population-based comparison group. Physical performance was lower among survivors and was associated with not living independently (odds ratio [OR], 5.0; 95% confidence interval [CI], 2.0-12.2) and not attending college (OR, 2.3; 95% CI 1.2-4.4). CONCLUSIONS Muscle strength and fitness values among BT survivors were similar to those among individuals aged > or = 60 years and were associated with physical performance limitations. Physical performance limitations were associated with poor outcomes in home and school environments. The current data indicated an opportunity for interventions targeted at improving long-term physical function in this survivor population.

Abstract
INTRODUCTION There is a lack of data on physical activity (PA) and fitness of adolescent and young adult very long-term survivors of childhood acute lymphoblastic leukemia (ALL). METHODS We studied 21 childhood ALL long-term survivors (aged 16-30 years, median time since diagnosis 15.9 y), diagnosed in 1986-1996, with age- and sex-matched controls. Peak oxygen uptake (VO(2 peak)) and muscle strength were measured and physical activity index (PAI; MET h/week) calculated. RESULTS Mean VO(2 peak) of the ALL survivors was 34.8 ± 9.3 ml/kg/min. This was 14% lower than that of the controls (-5.7 ml/kg/min, 95% CI -9.4 to -1.9, p=0.01), and all the 11 female survivors performed below the age-adjusted reference values. The survivors also performed poorer in the sit-up and maximal jump tests (p=0.02 and p=0.004). Body mass index and PAI were similar in survivors and controls (p=0.34 and p=0.52). Nonetheless, as much as 30% of the male survivors and 36% of the female survivors had PAI ≤ 5 indicating very low levels of physical activity (PA). CONCLUSIONS Insufficient PA and poor physical fitness are clinically important issues in childhood ALL long-term survivors treated with modern protocols. Girls seem to be especially at risk. PA and better physical fitness decrease cardiovascular mortality irrespective of weight. Thus, PA should be promoted throughout and after the treatment for ALL. IMPLICATIONS FOR CANCER SURVIVORS Since insufficient PA and poor physical fitness are an issue in very long-term ALL survivors, they should be informed on the benefits of physical activity, and be strongly encouraged to adopt a physically active lifestyle.

Abstract
Observational research has shown that the physical activity levels of survivors of hematological cancer are low, with deleterious health consequences. This review summarizes the research on exercise interventions in adult and pediatric hematological cancer survivors. We searched MEDLINE, SPORTDiscus, CINAHL, Embase, Cochrane and PEDro through September 2009 for exercise intervention studies in children and adults with any type of hematological cancer. In the 24 adult intervention studies reviewed, we found strong evidence (that is, > or =3 high-quality studies and > or =75% reporting a significant benefit) for a benefit on body composition. Weak, but promising, evidence (> or =3 high-quality studies, but <75% reporting a significant benefit) was found for cardiorespiratory fitness, fatigue, muscle strength, physical functioning and quality of life. In pediatric interventions (13 studies), we found strong evidence for a benefit on muscle strength and cardiorespiratory fitness, particularly, if training was conducted in the hospital setting. Evidence is weak for ankle dorsiflexion, physical functioning and body composition. No exercise-related risks were identified in adults or children studies. Though more randomized controlled trials are needed, a growing body of literature supports the notion that regular physical activity is safe and has potential benefits for both adult and pediatric hematological cancer survivors.

Abstract
OBJECTIVE The aim of this study was to develop a 12-week exercise training program (comprising aerobic and strength exercises), and to study the feasibility and efficacy of this exercise program in children who survived acute lymphoblastic leukemia. SAMPLE AND METHODS A 12-week exercise program was developed and tested for feasibility in nine children who survived cancer. RESULTS From the 16 eligible children for the intervention, 9 participated, while 4 were able to complete the entire program. Feasibility of the program was scored by five children, two of them reported the program as being too demanding. The participating physiotherapists were satisfied with training methodology and training progress. The efficacy of the program on muscle strength, exercise capacity, functional mobility and fatigue showed no significant differences between pre and post training. CONCLUSION In designing a community-based exercise training program, not only the stage of the disease needs to be considered, but more so the age of the children, the variety of exercises, the location of implementation and even more importantly the views and motivation of the parents concerning the execution of an exercise training program. A careful balance between these parameters could lead to a greater adherence and by that, to a better outcome of these programs.

Abstract
OBJECTIVE To evaluate the physical function and fitness in survivors of childhood leukaemia 5-6 years after cessation of chemotherapy. MATERIALS AND METHODS Thirteen children (six boys and seven girls; mean age 15.5 years) who were treated for leukaemia were studied 5-6 years after cessation of therapy. Physical function and fitness were determined by anthropometry, motor performance, muscle strength, anaerobic and aerobic exercise capacity. RESULTS On motor performance, seven of the 13 patients showed significant problems in the hand-eye co-ordination domain. Muscle strength only showed a significantly lower value in the mean strength of the knee extensors. The aerobic and the anaerobic capacity were both significantly reduced compared to reference values. CONCLUSION Even 5-6 years after cessation of childhood leukaemia treatment, there are still clear late effects on motor performance and physical fitness. Chemotherapy-induced neuropathy and muscle atrophies are probably the prominent cause for these reduced test results. Physical training might be indicated for patients surviving leukaemia to improve fitness levels and muscle strength.

Abstract
OBJECTIVE The study examined the degree to which male and female survivors of acute lymphoblastic leukaemia (ALL) perceive effort at low and moderate intensity exercise in association with related physiological variables. MATERIALS AND METHODS Participants were 67 children. Thirty-five (14 boys and 21 girls) were long-time survivors of ALL and 32 (18 boys and 14 girls) were control subjects. The Children's Effort Rating Table (CERT) was used to measure whole-body perceived exertion at low and moderate intensity exercise. Peak oxygen uptake was measured using a motorized treadmill. CERT and physiological data were analysed using 2 x 2 mixed analyses of variance, appropriate t-tests and coefficients of correlation. RESULTS In absolute terms, boys treated for ALL found perception of effort to be more strenuous at both low (3.9 vs. 3.5 units) and moderate (6.1 vs. 5.3 units) intensity exercise than control subjects, although differences were not significant (p > 0.05); girls treated for ALL found perception of effort to be the same as controls at low intensity exercise (3.1 vs. 3.1 units) but slightly higher than controls at moderate intensity exercise (5.6 vs. 5.2 units); neither of these differences were significant (p > 0.05). When CERT values were adjusted for (.-)VO(2) peak (%) and heart rate (HR) peak (%) differences remained non-significant. There were no significant interactions (Intensity x Group) in males, but the interaction for (.-)VO(2) peak (%) was significant in females (p < 0.05). The main effect for Intensity (low and moderate) was significant for all variables in boys and girls (p < 0.0001). The main effect for Group (ALL and controls) identified significantly greater absolute (b.p.m.) and relative (%) HR values in ALL boys at low and moderate intensity exercise. In female ALL and control subjects the interaction (Intensity x Group) distinguished between (.-)VO(2) peak (%) at moderate intensity exercise and HR peak (%) at low and moderate intensity exercise. Coefficients of correlation between perceived effort and (.-)VO(2) peak (%) in boys and girls were low to high (0.28-0.76), and between absolute and relative HR were also low to high (0.33-0.73). There were low correlations between time 'off therapy' and perceived effort, (.-)VO(2) peak (%) and HR peak (%) (-0.003 to -0.49). CONCLUSION It was concluded that perception of effort in survivors of ALL at low and moderate intensity exercise was the same as that of control subjects. Correlations between perceived effort and physiological variables at moderate exercise were low to high, while those between perceived effort and time from treatment were generally weak.

Abstract
Childhood cancer survivors often experience complications related to cancer and its treatment that may adversely affect quality of life and increase the risk of premature death. The purpose of this manuscript is to review how data derived from Childhood Cancer Survivor Study (CCSS) investigations have facilitated identification of childhood cancer survivor populations at high risk for specific organ toxicity and secondary carcinogenesis and how this has informed clinical screening practices. Articles previously published that used the resource of the CCSS to identify risk factors for specific organ toxicity and subsequent cancers were reviewed and results summarized. CCSS investigations have characterized specific groups to be at highest risk of morbidity related to endocrine and reproductive dysfunction, pulmonary toxicity, cerebrovascular injury, neurologic and neurosensory sequelae, and subsequent neoplasms. Factors influencing risk for specific outcomes related to the individual survivor (eg, sex, race/ethnicity, age at diagnosis, attained age), sociodemographic status (eg, education, household income, health insurance) and cancer history (eg, diagnosis, treatment, time from diagnosis) have been consistently identified. These CCSS investigations that clarify risk for treatment complications related to specific treatment modalities, cumulative dose exposures, and sociodemographic factors identify profiles of survivors at high risk for cancer-related morbidity who deserve heightened surveillance to optimize outcomes after treatment for childhood cancer.

Abstract
Survivors of acute lymphoblastic leukaemia (ALL) are recognised to become overweight and this seems to worsen with increasing length of follow up. Increases in body fat appear to be more marked in girls than in boys and in those who have received prophylactic cranial irradiation. Physiological responses to exercise, both at submaximal and maximal levels, are different in ALL survivors compared to controls. Heart rate appears to be increased at low intensity exercise, possibly to maintain adequate cardiac output. Maximal aerobic capacity is reduced, signifying a lower level of physical fitness. Total daily energy expenditure (TDEE) under free living conditions appears limited due to low participation in physical activity. Associations exist between measures of energy expenditure and body fat, but whether these are cause or effect has yet to proven.

Abstract
Although for most children the process of atherosclerosis is subclinical, dramatically accelerated atherosclerosis occurs in some pediatric disease states, with clinical coronary events occurring in childhood and very early adult life. As with most scientific statements about children and the future risk for cardiovascular disease, there are no randomized trials documenting the effects of risk reduction on hard clinical outcomes. A growing body of literature, however, identifies the importance of premature cardiovascular disease in the course of certain pediatric diagnoses and addresses the response to risk factor reduction. For this scientific statement, a panel of experts reviewed what is known about very premature cardiovascular disease in 8 high-risk pediatric diagnoses and, from the science base, developed practical recommendations for management of cardiovascular risk.
