Brief Summary:

The purpose of the study is to find out the highest dose per fraction of hypofractionated Intensity-Modulated Radiation Therapy (Hypo-IMRT) that can be safely given with temozolomide chemotherapy.

Condition or disease	Intervention/treatment	Phase
Glioblastoma Multiforme	Radiation: Hypofractionated Intensity-Modulated Radiation Therapy; Drug: Temozolomide	Phase 1

Detailed Description:

Hypo-IMRT is given in fewer treatments than conventional radiation therapy. This will be a dose per fraction escalation study. A dose per fraction escalation study means that successive groups of patients will receive higher doses per fraction of radiation while keeping the total dose of radiation the same (60 Gy, Gy is a radiation unit). The radiation dose per fraction will be increased and the numbers of radiation treatments will be decreased until a fraction dose is reached at which there are unacceptable side effects compared with possible benefit. Which group subjects are assigned to will depend on what stage the study has reached at the time the subject decide to participate.

This research is being done because with current standard radiation therapy (A total dose of 60 Gy given 2 Gy a day over 6 weeks) the outcome is very poor. New and more effective radiation therapy methods are desperately needed for patients with GBM.

In this study, radiation therapy is given together with chemotherapy of Temozolomide.

This study is also designed to monitor the level of some of the known cytokines (specific proteins in the blood) before and after radiation, and in meantime to screen unknown proteins in patients' blood before and after radiation therapy. Hopefully, this will provide some clues for future study of monitoring radiation damage, and possibly new therapeutic approach for patients with GBM.

Arm

Intervention/treatment

Experimental: Glioblastoma Multiforme Patients; Hypofractionated Intensity-Modulated Radiation Therapy (Hypo-IMRT) Combining with Temozolomide (TMZ) Chemotherapy

Radiation: Hypofractionated Intensity-Modulated Radiation Therapy; All patients will receive one fraction of radiation therapy a day, 5 days a week, Monday through Friday. Radiation fraction size and number of fractions depend on dose fraction level the patient is assigned to. Drug: Temozolomide; Temozolomide will be administered orally, once a day starting on the first day of radiation, for 28 consecutive days during radiation, and after radiation for those patients completing radiation in less than 28 days.; Other Name: Temodar

Outcome Measures

Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :

1. To identify the maximum dose per fraction of IMRT a patient can tolerate while keeping the total radiation dose at 60 Gy, provided concurrently with daily oral temozolomide chemotherapy [ Time Frame: Up to 60 days ]
   To determine the frequency of patients developing >= grade 3 acute and delayed toxicities attributable to radiotherapy. Acute radiotherapy toxicities are defined as those toxicities which occur during and within 30 days from the completion of radiotherapy and delayed toxicity are those developed at least 30 days after the last dose of radiation.

Secondary Outcome Measures :

1. Progression-free survival [ Time Frame: Until disease progression ]
   To monitor the level of some of the known and unknown cytokines or proteins before and after Hypo-IMRT and correlate it with the incidence of acute and late neurotoxicity. Quality of life assessment before and after treatment.
