  • Central Nervous System Tumor


RATIONALE: Drugs used in chemotherapy, such as carboplatin, vincristine, and temozolomide, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving more than one drug may kill more tumor cells. PURPOSE: This pilot study is studying giving carboplatin and vincristine together with temozolomide in treating children with progressive and/or symptomatic low-grade glioma.

Study summary:

OBJECTIVES: Primary - Determine the feasibility and toxicity of an induction and maintenance regimen comprising carboplatin, vincristine, and temozolomide in children with progressive and/or symptomatic low-grade gliomas. Secondary - Determine response rate in patients treated with this regimen. - Determine 3-year progression-free survival and overall survival of patients treated with this regimen. - Correlate response and progression-free survival with the genomic profile of tumors in patients treated with this regimen. OUTLINE: This is a pilot study. - Induction therapy: Patients receive carboplatin IV over 1 hour on days 1, 8, 15, and 22; vincristine IV on days 1, 8, 15, 22, 29, and 36; and oral temozolomide on days 43-47. Four weeks after the completion of induction therapy, patients achieving stable or responding disease proceed to maintenance therapy. - Maintenance therapy: Patients receive carboplatin and temozolomide as in induction therapy and vincristine IV on days 1, 8, and 15. Treatment repeats every 10 weeks for a total of 6 courses in the absence of disease progression. Patients are followed every 3 months for 1 year, every 4 months for 1 year, every 6 months for 1 year, and then annually thereafter. PROJECTED ACCRUAL: A total of 30-50 patients will be accrued for this study within 2 years.
