Purpose: Children with acute lymphoblastic leukemia (ALL) are at increased risk of obesity and deconditioning from cancer therapy. This pilot study assessed feasibility/initial efficacy of an exercise intervention for patients with ALL undergoing maintenance therapy., Methods: Participants were aged 5 to 10 years, receiving maintenance therapy, in first remission. A 6-month home-based intervention, with written and video instruction, was supervised with weekly calls from an exercise coach. Pre- and poststudy testing addressed strength, flexibility, fitness, and motor function., Results: Seventeen patients enrolled (participation 63%). Twelve (71%) finished the intervention, completing 81.7 ± 7.2% of prescribed sessions. Improvements of 5% or more occurred in 67% for knee and 75% for grip strength, 58% for hamstring/low-back and 83% for ankle flexibility, 75% for the 6-Minute Walk Test, and 33% for performance on the Bruininks-Oseretsky Test of Motor Proficiency Version 2., Conclusions: This pilot study demonstrated that exercise intervention during ALL therapy is feasible and has promise for efficacy.

Background: Low levels of physical activity, musculoskeletal morbidity and weight gain are commonly reported problems in children with cancer. Intensive medical treatment and a decline in physical activity may also result in reduced motor performance. Therefore, simple and inexpensive ways to promote physical activity and exercise are becoming an increasingly important part of children's cancer treatment., Methods: The aim of this study is to evaluate the effect of active video games in promotion of physical activity in children with cancer. The research is conducted as a parallel randomized clinical trial with follow-up. Patients between 3 and 16 years old, diagnosed with cancer and treated with vincristine in two specialized medical centers are asked to participate. Based on statistical estimates, the target enrollment is 40 patients. The intervention includes playing elective active video games and, in addition, education and consultations for the family. The control group will receive a general recommendation for physical activity for 30 minutes per day. The main outcomes are the amount of physical activity and sedentary behavior. Other outcomes include motor performance, fatigue and metabolic risk factors. The outcomes are examined with questionnaires, diaries, physical examinations and blood tests at baseline and at 2, 6, 12 and 30 months after the baseline. Additionally, the children's perceptions of the most enjoyable activation methods are explored through an interview at 2 months., Discussion: This trial will help to answer the question of whether playing active video games is beneficial for children with cancer. It will also provide further reasoning for physical activity promotion and training of motor skills during treatment., Trial Registration: ClinicalTrials.gov identifier: NCT01748058 (October 15, 2012).

Background: Patients with acute leukemia experience a substantial symptom burden and are at risk of developing infections throughout the course of repeated cycles of intensive chemotherapy. Physical activity in recent years has been a strategy for rehabilitation in cancer patients to remedy disease and treatment related symptoms and side effects. To date, there are no clinical practice exercise guidelines for patients with acute leukemia undergoing induction and consolidation chemotherapy. A randomized controlled trial is needed to determine if patients with acute leukemia can benefit by a structured and supervised counseling and exercise program., Methods/design: This paper presents the study protocol: Patient Activation through Counseling and Exercise--Acute Leukemia (PACE-AL) trial, a two center, randomized controlled trial of 70 patients with acute leukemia (35 patients/study arm) following induction chemotherapy in the outpatient setting. Eligible patients will be randomized to usual care or to the 12 week exercise and counseling program. The intervention includes 3 hours + 30 minutes per week of supervised and structured aerobic training (moderate to high intensity 70-80%) on an ergometer cycle, strength exercises using hand weights and relaxation exercise. Individual health counseling sessions include a self directed home walk program with a step counter. The primary endpoint is functional performance/exercise capacity (6 minute walk distance). The secondary endpoints are submaximal VO₂ max test, sit to stand and bicep curl test, physical activity levels, patient reported outcomes (quality of life, anxiety and depression, symptom prevalence, intensity and interference). Evaluation of clinical outcomes will be explored including incidence of infection, hospitalization days, body mass index, time to recurrence and survival. Qualitative exploration of patients' health behavior and experiences., Discussion: PACE-AL will provide evidence of the effect of exercise and health promotion counseling on functional and physical capacity, the symptom burden and quality of life in patients with acute leukemia during out patient management. The results will inform clinical practice exercise guidelines and rehabilitation programs for patients undergoing treatment for acute leukemia. Optimizing the treatment and care pathway may ease the transition for patients from illness to the resumption of everyday activities., Trial Registration: ClinicalTrials.gov Identifier: NCT01404520.

Background and Purpose: As the survival rate for acute lymphoblastic leukemia (ALL) in childhood increases, long-term sequelae are a growing concern. This cross-sectional, descriptive study compared the balance skills of children and youth who have had ALL with those of comparable subjects and explored associations with demographics, therapy, physical activity, and health-related quality of life (HRQL)., Subjects: Ninety-nine subjects treated previously for ALL and 89 comparison subjects were examined., Methods: Measures included the Bruininks-Oseretsky Test of Motor Proficiency (BOTMP) balance subtest, the Children's Self-perceptions of Adequacy in and Predilection for Physical Activity Scale (CSAPPA), and the Health Utilities Index (HUI), a measure of HRQL., Results: The children and youth who had ALL had poorer balance than the comparison subjects (BOTMP = 10.55 and 16.30, respectively) and lower CSAPPA scores (57.72 and 63.72, respectively) and HUI scores (0.86 and 0.97, respectively). Regression analyses identified exposure to cranial irradiation, being overweight, lower CSAPPA scores for adequacy, and lower HUI single-attribute scores for cognition as predictors of lower balance scores in subjects who had ALL., Discussion and Conclusion: Balance abilities in subjects treated for ALL were compromised, and several factors were associated with this deficit.

Aims: To investigate the differences in perception of quality of life between parents of chronically ill children and paediatricians at diagnosis and follow up. Quality of life was assessed using the (HUI3)., Methods: Longitudinal study (July 1999-January 2002) of 37 paediatricians and 181 parents of patients (children aged 1-17 years) with cystic fibrosis admitted for a pneumonia or patients with newly diagnosed acute lymphatic leukaemia, juvenile idiopathic arthritis, or asthma. Main outcome measure was percentage agreement on the attributes of the HUI3 between parents and paediatricians., Results: Differences in perception of health and wellbeing between paediatricians and parents of children with a chronic disease were found, not only at diagnosis but also after a period of follow up. Differences were particularly clear in the subjective attributes emotion (range of agreement 28-68%) and pain/discomfort (range of agreement 11-33%). In all patient groups, at baseline and follow up, the paediatrician assessed the patient to have less pain/discomfort in comparison to the parents. Despite a prolonged patient- paediatrician relationship, differences at follow up did not decrease compared to baseline., Conclusion: At the onset of a chronic disease, but also after a period of follow up, quality of life of paediatric patients may be misunderstood by healthcare professionals, especially in the subjective attributes. Systematic assessment of quality of life may contribute to better understanding between physicians and parents.

Aim: To evaluate academic career in long term survivors of childhood acute lymphoblastic leukaemia (ALL), in comparison to their healthy siblings., Patients: Ninety four children treated for ALL with cranial irradiation 18 or 25 Gy and intrathecal methotrexate as CNS prophylaxis. Median age at evaluation was 20 years; median follow up since diagnosis was 15 years at the time of the study., Methods: Patients and their 134 siblings completed a questionnaire on school career. The percentage of referrals to special primary schools for learning disabled, and the final level of secondary education in patients and siblings were compared, using a six point classification. Within the patient group, the effect of possible risk factors (age at diagnosis, irradiation dose, and gender) was investigated., Results: Significantly more patients than siblings were placed in special educational programmes. A significant difference was found for level of secondary education. No effect of gender or irradiation dose was found, but younger age at diagnosis was significantly related to both referrals and school levels., Conclusion: Treatment for childhood ALL with cranial irradiation and chemotherapy at a young age is clearly associated with poorer academic career.
