Active clinical trials for "Central Nervous System Neoplasms"

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Chemotherapy combined with radiation therapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of temozolomide followed by radiation therapy in treating children who have newly diagnosed malignant central nervous system tumors.

Phase I/II trial to study the effectiveness of pyrazoloacridine plus carboplatin in treating patients who have recurrent glioma. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

Phase II trial to study the effectiveness of rebeccamycin analogue in treating children who have solid tumors or non-Hodgkin's lymphoma. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of hydroxyurea in treating patients who have recurrent and/or unresectable meningioma.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of nitrocamptothecin in treating patients who have glioblastoma multiforme.

RATIONALE: Brachytherapy uses radioactive material to kill cancer cells remaining after surgery. PURPOSE: Phase I trial to study the effectiveness of brachytherapy in treating patients who have recurrent malignant glioma.

RATIONALE: Drugs used in chemotherapy, such as carboplatin and vincristine, work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining carboplatin and vincristine with radiation therapy followed by adjuvant chemotherapy may kill more tumor cells. PURPOSE: Randomized phase II trial to study the effectiveness of combination chemotherapy plus radiation therapy followed adjuvant chemotherapy in treating young patients who have newly diagnosed high-risk CNS embryonal tumors.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of vinorelbine in treating children with recurrent or refractory cancer.

RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: Phase I trial to study the effectiveness of monoclonal antibody therapy in treating patients who have leptomeningeal metastases.

Phase I trial to study the effectiveness of O6-benzylguanine and carmustine in treating children who have refractory CNS tumors. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.
