In summary, the overall prognosis of glioblastoma (GBM) patients remains poor. Although clinical gains have been achieved in the past, these have been modest, with a majority of patients succumbing to local disease progression within 2 years. New strategies for treatment need to be identified which enhance local control above the current treatment regimen in order to achieve further clinical gains in this disease. Favorable early experience with magnetic resonance spectroscopy imaging (MRSI) demonstrates that metabolic imaging can identify active tumor beyond standard MRI as well as high risk regions at risk for local failure. There is also clinical evidence that limited field dose escalation with either simultaneous integrated boost (SIB) or stereotactic radiosurgery (SRS) is feasible and safe. Coupling these findings provide the rationale for this proposed Phase II trial designed to define efficacy and toxicity of the novel treatment approach of whole brain volumetric 3D MRSI guided dose-escalated radiation therapy (RT) in newly diagnosed GBM patients.


Inclusion Criteria: - Histologically proven diagnosis of glioblastoma (WHO grade IV). Since gliosarcoma is a variant of glioblastoma, gliosarcoma is also an eligible diagnosis. - The tumor must have a supratentorial component - Patients must have recovered from the effects of surgery, postoperative infection and other complications - Karnofsky performance status >/= 70 - Age >/= 18 years - Adequate bone marrow function defined as follows: - Absolute neutrophil count (ANC) >/= 1500 cells/mm3 - Platelet count >/= 100,000 cells/mm3 - Hemoglobin >/= 10.0 g/dL (Note: the use of transfusion or other intervention to achieve Hgb >/= 10.0 g/dL is acceptable.) - Patients on full-dose anticoagulants (e.g., warfarin or LMW heparin) must meet both of the following criteria: - No active bleeding or pathological condition that carries a high risk of bleeding (e.g., tumor involving major vessels or known varices) - In-range INR (usually between 2 and 3) on a stable dose of oral anticoagulant or on a stable dose of low molecular weight heparin - Adequate renal function, defined as follows: - BUN </= 30 mg/dL - Serum creatinine </= 1.5 x ULN - Adequate hepatic function, as defined below: - Bilirubin </= 1.5 normal range - ALT </= 3x normal range - AST </= 3x normal range - Patients must not be pregnant (positive pregnancy test) or breast feeding; pregnancy test must be done within 7 days prior to registration. Effective contraception (men and women) must be used in patients of child-bearing potential while on study treatment and for 6 months after. - Ability to understand and the willingness to sign a written informed consent document - Ability to have MRI Scans - Ability to swallow capsules Exclusion Criteria: - Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 3 years (for example, carcinoma in situ of the breast, oral cavity or cervix are all permissible) - Recurrent malignant glioma or evidence of leptomeningeal spread - Metastases detected below the tentorium or beyond the cranial vault - Prior use of Gliadel wafers or any other intratumoral or intracavitary treatment - Prior radiotherapy to the head or neck (except for T1 glottic cancer), resulting in overlap of radiation therapy fields - Prior radiation therapy or chemotherapy for glioblastoma - Severe, active co-morbidity, defined as follows: - Symptomatic congestive heart failure of New York heart Association Class III or IV - Unstable angina pectoris, symptomatic congestive heart failure, myocardial infarction within the last 6 months, serious uncontrolled cardiac arrhythmia or any other clinically significant cardiac disease - Severely impaired lung function as defined as spirometry and DLCO that is 50% of the normal predicted value and/or 02 saturation that is 88% or less at rest on room air - Uncontrolled diabetes as defined by fasting serum glucose >1.5 x ULN - Active (acute or chronic) or uncontrolled severe infections requiring intravenous antibiotics - Liver disease such as cirrhosis, chronic active hepatitis or chronic persistent hepatitis - Acquired immune deficiency syndrome (AIDS) based upon current CDC definition or known HIV seropositivity. Note, however, that HIV testing is not required for entry into this protocol. The need to exclude patients with HIV/AIDS from this protocol is necessary because the treatments involved in this protocol may be significantly immunosuppressive. - Active connective tissue disorders, such as lupus or scleroderma, that in the opinion of the treating physician may put the patient at high risk for radiation toxicity - Other major medical illnesses or psychiatric impairments that in the investigator's opinion will prevent administration or completion of protocol therapy - Pregnancy - Women who are breast feeding - Prior allergic reaction to temozolomide - Treatment on any other therapeutic clinical protocol - Impairment of gastrointestinal function or gastrointestinal disease that may significantly alter their absorption of temozolomide (e.g. ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome or small bowel resection) - Contraindications to MRI including but not limited to, pacemaker, aneurysm clips, neurostimulators, cochlear implants, metal in eyes, steelworker or other implants - Need to continue treatment with any prohibited medication (e.g. antioxidants) or have not completed the appropriate washout period.
