Efficacy of interdisciplinary rehabilitation in child cancer survivors: Impact on physical fitness, fatigue and body composition after 1-year follow-up

Abstract

Objective: Childhood cancer survivors experience reduced physical activity level, participation as well as health-related quality of life. This prospective, pre-/post-intervention and follow-up cohort study aims to determine the efficacy of an interdisciplinary rehabilitation on improving physical fitness, fatigue and body composition.

Methods: A total of 24 childhood cancer survivors (mean age: 12.15 years ± 3.2; 14 females; 10 males) were recruited 6 months after medical treatment and received a 4-month interdisciplinary intervention. Cardiorespiratory fitness (PredVO_2peak and PredLoad_max ), body composition (dry lean weight) and quality of life (general fatigue) were assessed at baseline, post-intervention and 1-year follow-up. Linear mixed models were used to analyse data.

Results: Linear mixed modelling revealed a significant main effect of time on predicted maximal load (F = 13.189, df = 36.179, p < 0.001), dry lean weight (F = 64.813, df = 37.019, p < 0.001) but also significant improvement of general fatigue score (-9.039 ± 4.300, 95% CI -17.741 to -0.336, p = 0.042), indicating a decline in general fatigue.

Conclusion: With emerging evidence that physical activity is safe and feasible, together with increasing numbers of childhood cancer survivors at risk for long-term chronic co-morbidities, this study advocates for better access to interdisciplinary rehabilitation programmes in order to improve their physical condition and their body composition and reduce fatigue.
