Active clinical trials for "Central Nervous System Neoplasms"

RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy used to kill tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of cyclophosphamide when given together with combination chemotherapy and a peripheral stem cell transplant in treating patients with malignant solid 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 nitrocamptothecin in treating patients who have glioblastoma multiforme.

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.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the safety of delivering intrathecal busulfan in children and adolescents who have refractory CNS cancer and to estimate the maximum tolerated dose of this treatment regimen.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of topotecan plus carmustine in patients with recurrent primary malignant glioma.

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether radiation therapy combined with chemotherapy is more effective than radiation therapy alone in treating patients with low-grade glioma. PURPOSE: Phase II/III trial to evaluate observation and to compare the effectiveness of radiation therapy with or without combination chemotherapy in treating patients with low-grade glioma.

RATIONALE: 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. PURPOSE: Phase II trial to study the effectiveness of cisplatin and etoposide in treating patients with CNS 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 arsenic trioxide in treating children who have advanced neuroblastoma or other solid tumors.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Peripheral stem cell transplantation or bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of combining temozolomide, thiotepa, and carboplatin followed by peripheral stem cell transplantation or bone marrow transplantation in treating patients who have brain cancer.

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.
