Following surgery for Gross total resection and Gliadel(R) wafers implanted , the patient will receive a one-day GammaKnife(R) stereotactic radiosurgery procedure and will also take temozolomide (Temodar(R)) chemotherapy daily for six weeks with a one month break before taking temodar for additional 12 monthly cycles.

Following surgery for Gross total resection and Gliadel(R) wafers implanted , the patient will receive six weeks of standard fractionated radiation therapy plus daily temozolomide (Temodar(R)) chemotherapy for six weeks. This is followed by a one month break before taking temodar for additional 12 monthly cycles.

Complete removal of tumor and implant of Gliadel(R) wafers that are small, dime-sized wafers designed to deliver the chemo drug, carmustine, directly into the cavity made when the brain tumor was removed.

Gross total resection and Gliadel(R) wafers implanted

GammaKnife® (GK) radiosurgery dose of 15 Gy in one fraction to the resection cavity margin

GammaKnife(R) stereotactic Radiosurgery

standard fractionated RT of 60 Gy in 30 fractions (over approximately six weeks)

Standard fractionated radiation therapy

temozolomide 75 mg/m2 daily for 42 days, will be administered to all patients beginning within 24 hours of GK/RT initiation as is routine clinical care. There will be a one month drug holiday following the 42 days before adjuvant chemotherapy begins. Adjuvant temozolomide administered 5 days monthly at 150-200 mg/m2/day will be administered for 12 months as is routine clinical care.

A glioblastoma (GBM) is the most common malignant primary brain tumor, yet it is not easy to control. Recent studies show that survival improves for patients who get aggressive surgery to remove a tumor before starting radiation (RT) and chemotherapy (chemo) treatment. Surgery, RT and chemo are part of regular cancer care for GBM. RT is usually done in daily doses 5 days a week over about 6 weeks. Beams of radiation are aimed at the tumor site plus some of the normal brain tissue around the tumor area. GammaKnife® (GK) radiosurgery also delivers radiation but in a larger dose over one day. GK sends beams to a precise target (tumor location) and very little normal brain tissue that is nearby. This study will compare GK treatment to the usual RT treatment after surgery, and with chemo.

We want to know:

* How well each treatment keeps the tumor from growing back.
* What the effects (good and bad) of the treatments are.
* How you rate your quality of life.
* How the treatment affects your ability to think, understand, reason, and remember.
* How you rate your ability to think, understand, reason, and remember.
* If using a certain type of MRI scan can show the difference between new tumor growth and changes caused by treatment.
* If certain features found in tumor cells can help doctors predict how tumors will respond to treatment.

The primary purpose of this study is to determine if single fraction GK radiosurgical treatment to the resection bed can achieve equivalent local control and survival for patients with GBM after GTR, Gliadel® implant and temozolomide therapy compared to patients receiving standard postoperative RT with temozolomide, but offer improved quality of life and preserve cognitive function.

In Phase I, it is proposed that 20 patients with newly diagnosed glioblastoma multiforme (GBM) undergo gross total resection (GTR) with Gliadel® (carmustine) wafer implantation to the resection cavity at that time will be eligible for study. These patients will then receive Gamma Knife® (GK) radiosurgery to the resection cavity margin within 4 weeks following surgical resection and within 24 hours of starting temozolomide (Temodar®) induction therapy. Temozolomide (Temodar®) maintenance therapy would be administered for 12 months.

In Phase II, it is proposed that 60 patients with newly diagnosed glioblastoma multiforme (GBM) undergo gross total resection (GTR) with Gliadel® (carmustine) wafer implantation to the resection cavity at the time of initial resection will be eligible for study. These patients will then be randomized to either standard fractionated conformal radiation therapy (RT) or Gamma Knife® (GK) radiosurgery to the resection cavity margin. Fractionated RT would be administered with concurrent temozolomide Gamma knife® radiosurgery to the resection cavity margin will be administered within 24 hours of starting temozolomide induction therapy. Both the GK and RT will be administered within 4 weeks following surgical resection. Temozolomide (Temodar®) maintenance therapy would be administered to all patients in both arms of the study for 12 months.

It is believed that all patients will benefit from enrollment in the study regardless of the treatment arm to which they are randomized. All patients will be receiving focally aggressive surgical resection with Gliadel® implant in addition to temozolomide for prevention of both focal and distant recurrence.

Patients who are randomized to receive GK radiosurgical treatment to the resection bed margin may benefit from increased local control based on a prior non-randomized study. However these patients will be treated in a non-standard fashion and may be subjected to a higher incidence of focal radiation necrosis or a higher incidence of failure beyond the resection margin compared to standard patients.

The GK treated patients however, will be spared the standard 6 weeks of RT postoperatively. It is hypothesized that those receiving GK will therefore have an improved quality of life with respect to having less fatigue, lack of hair loss and a decreased incidence of delayed cognitive decline associated with standard RT.

Utility of perfusion MRI imaging for detection and differentiation between radiation toxicity and tumor recurrence

A new gamma knife cell culture bioassay developed at our center will be utilized to determine if it has a predictive value of responsiveness to radiosurgery in the clinical setting.

health related quality of life (HRQOL) evaluations using the EORTC Quality of Life Questionnaire-Core 30/Brain Cancer Module-20 (EORTC-QLQ C30/BCM20) and the The Functional Assessment of Cancer Therapy-Brain (FACT-Br, version 4) and cognition, (FACT-Cog, version 3) questionnaires.

Intellectual functioning, processing speed, attention and concentration, language and verbal fluency and motor skill as well as mood, depression, and memory assessments will be done prior to RT/GK treatment and at 4 month intervals. A self-report of perceived cognition, will also be completed by patient. Therefore, there will be both an objective measurement of cognition and subjective measurement as a part of quality of life.
