Subjects will receive surgery + Gliadel® wafer implantation + Limited Field Radiation Therapy to a dose of 61.2 Gy with concomitant daily temozolomide. Up to 8 wafers will be implanted into the tumor resection cavity (depending upon its size) after maximal tumor resection. Between days 10 and 30 all subjects will begin a standard course of post-operative limited field radiation therapy to the tumor site and a surrounding margin, with concomitant daily temozolomide (75mg/m2 x 7 d/wk for 6 weeks, concomitant chemoradiotherapy phase). Beginning no later than 45 days following completion of radiation, temozolomide will be given at a dosage of 200 mg/m2 daily for five days on a 28 day schedule, for a total of 6 cycles (adjuvant chemotherapy phase). Subjects will be monitored weekly during chemoradiotherapy with CBC with differential and brief clinical assessment, and monthly during the adjuvant chemotherapy phase. Toxicity reports will be assessed every three months. Dose limiting toxicities (DLT) are defined in section 4.2. If toxic events unresponsive to planned dose modification exceed 20% of enrolled subjects the stopping rule will be met and the study will be discontinued. MRIs will be obtained no more than 72 hours post-op, and then prior to the first, third, and fifth cycles of monthly temozolomide. Additionally, a stealth MRI or CT scan (with or without contrast) will be done one week prior to radiotherapy for treatment planning at the discretion of the treating Radiation Oncologist. Following completion of the entire course of treatment subjects will be monitored clinically as well as with MRI every 3 months for survival and evidence of progression.
