Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
To assess toxicity and the maximally tolerated dose of N-acetylcysteine administered in conjunction with carboplatin, cyclophosphamide and etoposide phosphate BBBD, and delayed high dose sodium thiosulfate, in children with malignant brain tumors.
Interventions
administered i.v. over 30 to 60 minutes
(200 mg/m2/day; total dose 400 mg/m2) will be infused i.a. over 10 minutes, in 50-180 cc of normal saline.
(330 mg/m2/day; total dose 660 mg/m2) will be infused i.v. in 25-50 cc of normal saline, over approximately 10 minutes.
(200 mg/m2/day; total dose 400 mg/m2) will be infused i.v. in 25-100 cc of normal saline, over approximately 10 minutes, immediately following the cyclophosphamide.
(25%) delivered i.a. at a pre-determined flow rate over 30 seconds. The flow rate will be determined by iodinated contrast injection and fluoroscopy as the lowest infusion rate in which there is retrograde flow from the arterial catheter. The rate and volume of mannitol infused will be approximately 4-12 cc/sec x 30 seconds.
STS is available as a 25% (250 mg/ml) solution. The dose of STS administered 4 hours after carboplatin is 16 gm/m2. The dose of STS administered 8 hours after carboplatin is 16 gm/m2. Actual dose to be administered will be determined and mixed with an equivalent amount of sterile water (1 ml:1 ml) for infusion.
