Physical activity and childhood cancer.

This review provides a survey of studies investigating physical activity and exercise interventions in patients during tumor treatment and survivors of childhood cancer. PubMed and Medline databases were searched using relevant terms. References of selected papers were tracked. A total of 28 studies could be identified. Seventeen studies investigated physical activity, 11 studies determined the effect of activity enhancing interventions during and after therapy. Even though most studies showed limitations and results were not consistent, considerably reduced physical activity is highly probable in patients during and after therapy. Studies on interventions provided promising results and revealed challenges to be faced.
