Abstract

Background: The authors report the experience at the Children's Hospital Los Angeles with brain tumors diagnosed before 6 months of age, describing the characteristics of the patients, their tumors, treatment strategies, and prognostic factors. Methods: Thirty-three children who were identified between 1979 and 2005 were included. Twelve were female (36%). There were 11 gliomas, 9 choroid plexus tumors, 8 medulloblastomas and supratentorial primitive neuroectodermal tumors (PNET), 2 atypical teratoid/rhabdoid tumors (ATRT), and 1 each of ependymoma, craniopharyngioma, and immature teratoma. Locations of primary tumors included 21 supratentorial (64%) and 7 posterior fossa, and 5 tumors involved both compartments. The treatment strategies included 5 patients with biopsy only, 18 less than gross total resections (<GTRx), and 9 GTRx. Fourteen children (42%) received chemotherapy. Three patients (9%) received irradiation, 1 at initial diagnosis and 2 at relapse. Nine patients (27%) demonstrated metastases, 6 at diagnosis and 3 at relapse. Results: The Kaplan Meier analysis of event-free survival (EFS) and overall survival (OS) for all patients is 21 ± 9% and 35 ± 9% at 5 years. For the glioma patients, the 4-year OS is 48 ± 17%, while the 5-year OS for the medulloblastoma/PNET/ATRT patients is 12 ± 11% (p = .39). The 5-year OS for children achieving a GTRx is 64 ± 21% and for those with <GTRx is 27 ± 10% (p = .08).
