ABSTRACT
The diagnosis of cancer as well as accompanying acute and late effects of treatment are influencing physical activity behavior of patients with childhood cancer and survivors. Research has shown that a pediatric cancer diagnosis is associated with impairments of physical performance, and function, as well as reduced physical, and psychosocial, health conditions. From an ethical perspective, lack of knowledge of health care providers, lack of physical activity promotion, and environmental, and structural barriers to physical activity restrict children's right to move and actively engage in physical activities. Network ActiveOncoKids is a German-wide initiative with the main goal of enabling children, adolescents, and young adults with exercise opportunities during and after cancer treatment. Since the network's foundation in 2012, Network ActiveOncoKids focuses on: (1) physical activity support for patients and families, (2) policy change to establish structures and guidelines, and (3) generating evidence through scientific projects. The purpose of this paper is to present an overview of Network ActiveOncoKids structure, aims, and projects. This topical review will highlight the network's structural development, research work, and implementation progress of exercise programs for patients with pediatric cancer and survivors, link international collaborations, and discuss future directions.

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.

Regular physical activity is an important requirement for the development and the general health in childhood and adolescence. However, patients during and after treatment for childhood cancer show high levels of physical inactivity, and only a marginal extent of physical activity. In addition to the negative side effects of treatment, this lack of physical activity and exertion has further negative implications for their health, such as decrease in physical performance and health related quality of life. In order to reduce these negative effects and provide access to regular physical activity for children and adolescents with cancer, childhood cancer patients should participate in targeted physical exercise therapy sessions at the treating hospital. Physical activity promotion for children and adolescents with cancer is an effective measure to enhance or preserve functional mobility, physical performance and health related quality of life. Both the behavioral level (person) and the setting (environment) should be taken into account for a sustainable implementation of physical activity promotion in the treatment of childhood cancer. The Leipzig Movement Concept promotes physical activity both during and after treatment for childhood cancer. On the basis of the modular concept, factors influencing physical activity in childhood cancer, alongside requirements for the successful and long-term implementation of physical activity programs and clinical exercise therapy are described. Furthermore financing options, based on Book V § 43 of the German Social Welfare Code, are presented.

Background Exercise and adapted physical activity during and after treatment for childhood cancer have a large potential to diminish several side and late effects of treatment. However, the prevalence of such interventions is low. The aim of this investigation is to identify interventions in the clinical setting in Germany and to examine their quality and structural characteristics. Method 54 hospitals were investigated for the existence of relevant interventions and if applicable the quality and structural characteristics of these according to DIN EN 15224:2012 and further characteristics of structural quality in written form or by telephone. Results 48 hospitals took part in the investigation and filled out the questionnaire (CR 89%). Of these, 9 (19%) offer exercise therapy during treatment and/or aftercare. The remaining 39 (81%) did not offer exercise therapy at the time of investigation. Exercise therapy represents a permanent component of adjuvant treatment in the 9 identified hospitals. The qualifications of exercise therapy staff seem appropriate as well as conditions concerning rooms and equipment. Yet, funding of exercise therapy is mainly realized through donations and 3rd party funds. Conclusion The majority of childhood cancer patients in Germany do not have access to adapted physical activity during treatment or aftercare. The body of evidence for exercise therapy in the pediatric oncology setting is growing, as well as the network between exercise scientists/therapists in this field. To date, an exercise manual for pediatric oncology in German and a comprehensive financing option of such interventions via health insurance is not available.

Cancer- and treatment-related side effects in patients with childhood cancer may cause limitations in motor performance affecting activities of daily living (ADLs). Data focusing on long-term effects are available, but little is known with regard to the short-term perspective. Therefore, the purpose of this study was to assess muscle strength performance and quality of life (QoL) in children and adolescents with cancer at the beginning of primary treatment. Forty children and adolescents aged 5-18 years (mean: 11.39 ± 4.08 years) with different types of childhood cancer were enrolled. On average 36 ± 20.5 days after diagnosis, strength performance in 7 muscle groups was assessed by handheld dynamometry. KINDL questionnaires were completed to evaluate QoL (children's self-report and parents' report). All parameters were compared with age- and gender-matched reference values. Patients with childhood cancer showed significantly lower strength values in all muscle groups (P < .01) compared with age- and gender-matched controls. Most affected were the lower extremities, with a -57.1% ± 10.4%, median: -59.2%, minimum: -75.4%, maximum: -41.4% percentage deviation in knee flexion from healthy peers. Children themselves and parents assessed total QoL significantly below age- and gender-matched reference values (P < .01). Correlation between elbow flexion and self-reported QoL was detected. Broader correlations were found for the parents' report. Muscle weakness and decreased QoL in children and adolescents seem to persist already at the beginning of anticancer treatment. This underlines the need of counteracting measures, such as exercise intervention programs, starting as early as possible during the treatment process. Efforts on this topic are currently being carried out by our group.

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.
