In general QoL scored with the PEDQOL pilotquestionnaire was good for most of the childhood cancer survivors. Children with solid tumors show less impairment than children with leukemia/lymphoma. Therefore it could be suggested, that young age at diagnosis and the following longer period of being dependent on familial support, the isolation from peer groups and the longer way to become independent may be reflected by these results. To obtain reliable results how children with cancer express their QoL and what consequences illness, treatment and long term effects of therapy have on the childrens' QoL a multicenter prospective study is needed. This will be realized in the near future in a project on "Long term effects and quality of life in children with leukemia or medulloblastoma", which is supported by the "Kompetenznetz Pädiatrische Onkologie and Hämatologie".

Our results underline the influence of objective long term effects and subjective QoL on the Quality of Survival. Prospective evaluation will lead to new and important information with respect to the onset of somatic and psychosocial LF and possible coping strategies. These information will establish additional possibilities for initiation of primary and secondary rehabilitation processes.

A HEP can help to advance in physical fitness and coordination and may reduce bleeding tendency, but needs to be accomplished regularly. Patients are interested but the motivation to exercise at home is low. Disorders measured by motion analysis seem not to be sufficiently influenced by our surrogate training program.
