Aim: This study aimed to evaluate the clinical features, treatment approaches, and outcomes of glial tumors in children.
Material and Methods:Files (2006 to 2020) of children diagnosed with glial tumors and followed-up were reviewed retrospectively. Information regarding demographic and clinical characteristics, treatment approaches, and outcomes were retrieved from the patients\' files.
Results:Of the total of 180 pediatric patients diagnosed with brain tumors, 73 (40.6%) had glial tumors. The children with astrocytoma were in the age range of 218 years (median age: 8.7 years), while the ages of children with ependymoma ranged from three months to 10 years (median age: 3 years). This difference was statistically significant (p < 0.0001). The male to female ratio was 1.6. The most common symptoms or signs were headaches (n = 34, 46.6%), abnormal gait or coordination (n = 22, 30.2%), vomiting (n = 21, 28.8%), and cranial nerve palsies (n = 20, 27.4%). The pathological diagnoses were astrocytomas (n = 53, 72.6%), oligodendroglial tumors (n = 2, 2.7%), ependymoma (n = 15, 20.7%), and other glial tumors (n = 3, 4.1%). The most common tumor location was supratentorial (n = 42, 57.5%), while midline glioma was detected in seven patients. The 5-year overall survival (OS) rate of all glial tumors, astrocytoma, and ependymoma was 42%, 40%, and 55%, respectively. The 5-year OS rate of the tumor Grade I, II, III, and IV was 77.2%, 45%, 32%, and 0%, respectively (p < 0.0001). The 5-year OS rate of supratentorial, infratentorial, and spinal tumors was 25.6%, 63.6%, and 50%, respectively (p = 0.021). In Cox regression analysis, it was found that the tumor resection and grade had an effect on the tumor prognosis.
Conclusion:Treatment results are not satisfactory in high-grade astrocytomas. There is a need for new treatment approaches that would take cognizance of molecular features and adopt multidisciplinary approaches.
