575 malignant tumors were treated in the Childrens Hospital of Freiburg University during the years 1957--1974. This means that 0.86% of all hospital admissions had a newly recognized malignant neoplasia. There was no increase in the relative frequency of tumor admissions throughout these years. The most frequent tumor groups were expectedly leukemias (41.8%), central nervous system tumors (25.6%), lymphosarcomas (6.3%), Hodgkin's disease (5%), and neuroblastomas (5%). In comparison to tumor statistics comprising whole populations instead of admissions to a single hospital the relative frequency of leukemias and CNS-tumors is higher in our series. This may due to selective admissions of patients with different tumors to different treatment centers rather than to a higher incidence of these neoplasias in this area.
