Tumors of the central nervous system in children and adolescents.
2011
Multimodal treatment approaches for children with tumors of the central nervous system (CNS) have markedly contributed to improved survival. Before 1970, the survival rate among children with medulloblastoma, the most common malignant CNS tumor in children, was about 20%. At present, in contrast, cure can be achieved in more than 75% of children with a favorable constellation of risk factors. In this review article for clinicians, we give an overview of the current understanding of the pathology, presenting manifestations, early diagnosis, and treatment of CNS tumors in children and adolescents.We report the research findings of the German Treatment Network "HIT" and selectively review the …

Tumors of the CNS are the second most frequent malignancy in childhood and the most common of the solid tumors. An increase in CNS tumor rates during the past decades has been observed in a number of countries. One possibility is that improvements in diagnostics of CNS tumors contributed to the increasing trend. Another concern is that changes in environmental exposures may be responsible for the increasing incidence rates and a number of epidemiologic studies investigated factors like exposure to ionizing radiation, electromagnetic fields, or pesticides. In addition, prenatal exposures, for example from maternal diet, or the role of infectious agents were of particular interest. In this re…
