A prospective study on the health-related quality of life of children with brain and cranial base tumours from the age of 2 -7 years has now been started by the West German Proton Therapy Centre in Essen (WPE). “The rate of healing in children with cancer is now very high. Since the quality of life is becoming increasingly important in the oncology treatment concept, proton therapy is gaining in importance. It offers the possibility to preserve healthy tissue, reduce side effects and thus, increase the overall health-related quality of life”, explains Prof. Dr. med. Beate Timmermann, Director of the Clinic for Particle Therapy at WPE.
