Abstract

Background Childhood primary central nervous system (CNS) malignancies are one of the most important concerns in pediatric oncology.

Material In this historical cohort, 82 patients treated in Ali-Asghar Children's Hospital between 1996 and 2005 were evaluated for age, gender, type of treatment, tumor pathology, and survival.

Results The records of 38 female (46.3%) and 44 male (53.7%) patients were included. The mean age was 6.8 ± 3.39 years (6 months to 14 years); the frequency of medulloblastoma was significantly more than others (p = 0.012). Complete resection, radiotherapy, and chemotherapy were done in 47.5, 82.9, and 97.56%, respectively. Estimated 5 years overall and event-free survivals (EFSs) were approximately 68.5 and 35%, respectively. The patients with complete resected tumors had significantly better outcome (p = 0.013). Also, low-grade versus high-grade astrocytoma was significantly a better outcome (p = 0.01).

Conclusion The poor EFS with consideration of high number of progressive disease among our patients (50% unresectable tumor) suggests that children in Iran with CNS tumors had high quality of care but availability of advanced treatment protocol and sharing of cooperative trial study is essential for survival improvement. In addition to use more advanced methods and equipments of radiotherapy and chemotherapeutic drugs, we should seriously consider development of better surgical techniques to increase the rate of complete resection of malignant CNS tumors.
