Abstract
In the world, childhood and adolescent cancer is the main cause of nonaccidental mortality in developed countries, while in average and low income / per capita countries, only 10-20% of children diagnosed with this condition can be cured. Similar to international statistics, in Romania the most common types of tumors in children are blood cancers - leukemias or lymphomas, cerebral cancers and embryonic tumors. The complexity and severity of neoplastic disease determines the need for frequent hospitalizations of these patients not only for the purpose of diagnosis but also for the establishment and follow-up of the therapeutic behavior, so that for the best possible management and planning of resources of all kinds, it is necessary to periodically analyze the situation to allow for a more accurate knowledge of the temporo-spatial distribution of the episodes of admission caused by this condition.
