摘要：

Objectives: To estimate survival and evaluate prognostic factors of pediatric patients with central nervous system (CNS) tumors treated in a single center. Methods: Retrospective analysis of survival of 103 children with primary brain tumors diagnosed consecutively from January 2000 to December 2006. Cox regression was used for multivariate analysis of factors that affect overall survival to define possible prognostic factors. Results: Median and mean ages were 7.2 and 7.6 years. There was a male predominance (1.22: 1). Most patients had medulloblastomas or primitive neuroectodermal tumors (PNET, 38%), or low-grade astrocytomas (18%). The anatomic site of most tumors was the cerebellum (49%) and the brain stem (21%). Five-year survival after diagnosis was 84% for low-grade astrocytomas and 51% for medulloblastomas and PNET. Prognostic factors for overall survival were histopathological type (high-grade astrocytomas and ependymomas; hazard ratio = 3.7 to 3.9), surgery (hazard ratio of 0.5 for completely resected tumors) and radiotherapy (hazard ratio of 0.5 for patients who underwent radiotherapy). Conclusions: Overall survival of pediatric patients with brain tumors in this study was similar to that found in populations of the United States and Europe. The prognostic factors defined for overall survival are also similar to those published in previous studies.
