ObjectiveTo better characterize children with glioblastoma, assess outcomes, and identify prognostic factors associated with overall survival and progression-free survival in a relatively large cohort from a single institution.MethodsFor this retrospective review, 38 pediatric patients with a diagnosis of glioblastoma who were treated at The First Affiliated Hospital of Zhengzhou University between January 2015 and January 2020 were selected. Clinical and pathological characteristics, imaging, treatment, and survival variables were compared.ResultsThere were 24 boys and 14 girls with a median age of 11.5 years (range, 3-18 years). All patients underwent surgery, with gross total resection in 16 and subtotal resection in 22. Of patients, 18 received radiation combined with chemotherapy, 6 received radiation or chemotherapy alone, and 14 did not receive any adjuvant therapy. Contrast-enhanced magnetic resonance imaging of 21 patients showed rim enhancement, while heterogeneous enhancement was shown on imaging of the other 17 patients. Tumors were observed in hemispheric locations in 19 cases and in central locations in the others. Median overall survival was 10.5 months with a median progression-free survival of 6 months. Extent of resection, adjuvant therapy, and original site of tumor were identified as independent predictors for progression-free survival and overall survival on multivariate analysis. There were significant differences in prognosis among different enhancement characteristics; patients with rim-enhancing tumors had a better prognosis.ConclusionsPediatric glioblastoma carries a dismal prognosis. Maximum safe resection followed by adjuvant radiation with chemotherapy is considered standard treatment. Better outcomes are associated with hemispheric tumor locations and rim enhancement on magnetic resonance imaging.Copyright © 2021 Elsevier Inc. All rights reserved.
