简要总结
RATIONALE: Drugs used in chemotherapy, such as capecitabine, 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. Capecitabine may make tumor cells more sensitive to radiation therapy. Giving capecitabine together with radiation therapy may kill more tumor cells.
PURPOSE: This phase I trial is studying the side effects and best dose of capecitabine when given together with radiation therapy in treating young patients with newly diagnosed, nonmetastatic brain stem glioma or high-grade glioma.
详细描述
OBJECTIVES:
Primary
- Estimate the maximum tolerated dose of capecitabine rapidly disintegrating tablets (RDT) administered concurrently with radiotherapy in young patients with newly diagnosed, nondisseminated intrinsic brain stem glioma or high-grade glioma.
- Describe the dose-limiting toxicity in patients treated with this regimen.
Secondary
- Describe the safety profile of this regimen.
- Characterize the pharmacokinetics of capecitabine RDT in these patients.
- Explore the exposure-response relationship for measures of safety and effectiveness using pharmacokinetic and pharmacodynamic models.
- Describe the antitumor activity of this regimen observed in these patients.
- Estimate distributions of progression-free survival and survival in patients treated with this regimen.
- Characterize radiographic changes in tumor, using MRI, perfusion and diffusion MRI, and positron emission tomography (PET) scans, in patients treated with this regimen.
