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.

Official Title: | Phase I Dose Escalation Study of N-Acetylcysteine Administered in Conjunction With Carboplatin, Cyclophosphamide, and Etoposide Phosphate BBBD, in Children With Malignant Brain Tumors |

OUTLINE: This is a dose-escalation study of acetylcysteine.
Patients receive acetylcysteine IV over 30-60 minutes followed, at least 15 minutes later, by x-ray-guided femoral artery catheterization under general anesthesia on days 1 and 2. After placement of the catheter, patients receive cyclophosphamide IV over 10 minutes, etoposide phosphate IV over 10 minutes, mannitol intra-arterially (IA) over 30 seconds, and carboplatin IA over 10 minutes also on days 1 and 2. Patients then receive high-dose sodium thiosulfate IV over 15 minutes 4 hours after completion of carboplatin. Some patients may receive a second dose of sodium thiosulfate 8 hours after completion of carboplatin. Beginning 48 hours after the last dose of chemotherapy on day 2, patients receive filgrastim (G-CSF) subcutaneously once daily for 7-10 days or until blood counts recover. Treatment repeats every 4 weeks for up to 12 courses in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of acetylcysteine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. An additional 3 patients are treated at the MTD.
After completion of study treatment, patients are followed periodically.
