简要总结
RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, etoposide phosphate, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Mannitol may help chemotherapy work better by making it easier for these drugs to get to the tumor. Chemoprotective drugs, such as acetylcysteine and sodium thiosulfate, may protect normal cells from the side effects of chemotherapy. Giving acetylcysteine together with mannitol, combination chemotherapy, and sodium thiosulfate may be an effective treatment for malignant brain tumors.
PURPOSE: This phase I trial is studying the side effects and best dose of acetylcysteine when given together with mannitol, combination chemotherapy, and sodium thiosulfate in treating children with malignant brain tumors.
详细描述
OBJECTIVES:
Primary
- Determine the toxicity and maximum tolerated dose of acetylcysteine when given in combination with blood-brain barrier disruption treatment with mannitol, combination chemotherapy comprising cyclophosphamide, etoposide phosphate, and carboplatin, and delayed high-dose sodium thiosulfate in pediatric patients with malignant brain tumors.
Secondary
- Determine the blood/bone marrow toxicity of this regimen in these patients.
- Determine tumor response in patients treated with this regimen.
