BACKGROUND AND PURPOSE: Glioblastoma in the pediatric age group is relatively rare. As a result, it has been difficult to deduce any consistent clinico-radiological and pathological profiles on these patients. Also, the prognostic factors affecting the survival in pediatric glioblastoma are not as well defined as in adults. PATIENTS AND METHODS: In this retrospective series, 65 pediatric patients (age ≤ 18 years) from January 1995 to December 2011 with histopathologically proven diagnosis of intracranial glioblastoma were studied. Clinico-radiological, pathological, treatment, and follow-up data were collected. Progression-free and overall survivals were assessed using the Kaplan-Meier method. RESULTS: The male-to-female ratio was 2.6:1 with a mean age of 13.29 ± 4.53 years (range 2-18 years). Headache with or without vomiting (n = 51, 78 %), followed by seizures (n = 42, 65 %), and focal deficits (n = 31, 47 %) were the leading symptoms. Forty-nine (75 %) patients had tumors located superficially, whereas there were 16 patients with deeply located glioblastomas (25 %). Gross total tumor excision was achieved in 43 (66 %) patients, while the remaining patients had incomplete excision (n = 22, 34 %). Mean follow-up was 17.7 months (range 1.5-119 months). The median progression-free and overall survivals were 10 and 20 months, respectively. Extent of resection was found to be the independent predictor of survival (p value = 0.002). CONCLUSION: Pediatric glioblastomas are associated with longer progression-free as well as overall survivals. Extent of tumor resection is the strongest predictor of survival in pediatric glioblastoma. Hence, an aggressive surgical resection may fetch a better outcome in children with glioblastoma.
