简要总结
RATIONALE: Drugs used in chemotherapy, such as thiotepa, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy and radiation therapy after surgery may kill any tumor cells that remain after surgery.
PURPOSE: This phase II trial is studying how well thiotepa works together with radiation therapy in treating young patients with newly diagnosed malignant brain tumors.
详细描述
OBJECTIVES:
Primary
- Determine tumor response to adjuvant thiotepa followed by radiotherapy in pediatric patients with newly diagnosed malignant astrocytic tumors.
Secondary
- Determine the acute and chronic toxicity of thiotepa in these patients.
- Determine the variability in thiotepa metabolism by measuring plasma and cerebrospinal fluid pharmacokinetics of thiotepa and tepa in these patients.
- Develop a phase II study framework model, to determine the chemosensitivity to new, single-agent regimens in the treatment of high-grade (malignant) astrocytic tumors, including anaplastic astrocytoma, glioblastoma, giant cell glioblastoma, and gliosarcoma.
- Determine the incidence of distant neuraxial metastases in patients at the time of relapse.
- Determine the 1-year disease-free survival rate in patients treated with this regimen.
