Chemotherapy is commonly used in the treatment of children with high-grade glioma, although its usefulness is uncertain. We conducted a multi-institutional study to evaluate the efficacy of temozolomide given after radiotherapy in children with newly diagnosed high-grade glioma and unfavorable low-grade glioma (gliomatosis cerebri or bithalamic involvement). Optional window therapy of intravenous irinotecan (10 doses of 20 mg/m2 per cycle x 2) was given over 6 weeks. The 5-day schedule of temozolomide (200 mg/m2 per day) started 4 weeks after the completion of radiotherapy and continued for a total of 6 cycles. Thirty-one eligible patients (median age: 12.3 years) participated. Tumors most commonly involved cerebral hemispheres (n = 13, 42%) and thalamus (n = 14, 45%). Whereas six patients underwent radical resection, the remainder had limited surgery, including biopsy (n = 14, 45%). The predominant histologic diagnoses were glioblastoma multiforme (n = 15, 48%) and anaplastic astrocytoma (n = 10, 32%). Two patients had bithalamic grade II astrocytoma. Twenty-seven patients received radiotherapy (median dose: 59.4 Gy), including craniospinal irradiation in 3 because of leptomeningeal spread. Four patients did not receive radiotherapy in this study because of consent withdrawn (n = 2), toxicity during window therapy (n = 1), or at the physician's discretion (n = 1). Twenty-three patients received 112 cycles of temozolomide therapy. The 2-year progression-free and overall survival estimates were 11 +/- 5% and 21 +/- 7%, respectively. Although the heterogeneity of prognostic factors in our patients made assessment of treatment outcome more difficult, the addition of 6 cycles of temozolomide after radiotherapy did not seem to alter the poor outcome of these patients.
