[Oncologic after-care--a patient-oriented concept. Basic diagnostic plan for pediatric oncology patients].

With intensive treatment many children and young adults with cancer can be cured of their disease. Therefore, the recognition of late effects of therapy will become increasingly important. Future concepts of follow-up care in pediatric oncology will have to serve two purposes: First, to determine the status of the malignant disease with early diagnosis of relapse and second, to recognize relevant side effects of treatment. We present a comprehensive approach of follow-up care which is primarily based on the definition of risk criteria for the development of relevant organ toxicity after different treatment modalities. For each patient a standardized summary of therapy delivered is documented. According to the definition of the risk criteria an individualized schedule for follow-up is decided upon. We hope that this structured concept will result in appropriate patient care while keeping the diagnostic efforts and costs limited.
