The management of childhood brain tumors, which consist of many different histological subtypes, continues to be a challenge. Outcome, measured not only by survival rates but also by the effects of disease and therapy on quality of life, has improved over the past two decades for some tumor types, most notably medulloblastomas. For others, however, there has been little progress, and quality of life for long-term survivors remains suboptimal. Because of advances in our understanding of the biology underlying childhood brain tumors, treatments may change dramatically in the years ahead. Accordingly, survival rates may improve and long-term sequelae lessen.
