- Abstract
Introduction: The purpose of this review was to analyze outcomes for pediatric patients treated for more common (non-low grade glioma) primary central nervous system (CNS) tumors at a Regional (tertiary) Cancer Center. Comparison to reported results from other regional centres and results from the contemporary literature were made., Material and Methods: The records of pediatric patients treated with radiotherapy at the London Regional Cancer Center (LRCC) for more common (non-low grade glioma) primary CNS tumors between 1980 and 2001 were reviewed. Details regarding tumor presentation, treatment and outcome were analyzed., Results: Eighty-eight patients were eligible for the review. Twenty-nine patients with malignant glioma, 37 patients with medulloblastoma or primitive neuroectodermal tumor (PNET), 15 patients with brainstem glioma, 4 with ependymoma and 3 with germ cell tumors were treated during this time period. Average follow-up for the group was 5 years (range 4 months to 19 years). Five-year overall, progression free and cause specific survival were 45, 42 and 50%, respectively. For patients with malignant glioma median progression free and overall survival was 20 and 29 months. For patients with brainstem glioma median progression free and overall survival was 9 and 13 months. For medulloblastoma, 5-year progression free, and overall survival was 60 and 59%., Conclusions: RESULTS of this retrospective review of pediatric patients treated at a regional cancer center for primary CNS tumors (other than low grade glioma) were comparable to contemporary results reported by other Canadian centers and North American co-operative group trials.
