- Estimate the response rate, response duration and survival according to established response definitions [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]
- Determine the pharmacokinetics of high daily dosing of temozolomide in the transplant setting [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]

Before taking part in this study, subjects will have stem cells collected in a procedure called apheresis. Once on this study, subjects will be admitted to the hospital and receive daily doses of temozolomide by mouth for 5 days. Stem cells will be given back to subjects who will remain in the hospital until blood counts have recovered. Doses of temozolomide will range from 350 mg to 1500 mg/m(squared) daily for 5 days (total dose 1750 to 7500 mg/m(squared).

High dose chemotherapy and autologous stem cell transplant is an accepted treatment alternative for patients with brain tumors. Temozolomide has been approved for use by the United States Food and Drug Administration (FDA) for certain tumors of the brain. The doses of temozolomide given in this study will be higher than approved by the FDA and higher than those given in any prior studies.
Over 25 subjects will be enrolled on this study over a period of 5 years. This study will only be available at Tufts Medical Center.
