Clinical Trial Summary

There are preliminary studies that suggest that radiation therapy to areas of the brain containing cancer stem cells (in addition to the area where the tumor was surgically treated) may help patients with high-grade brain tumors live longer. The purpose of this study is to determine whether the addition of stem-cell radiation therapy to the standard chemoradiation will further improve the outcome. The investigators will collect information about the patient's clinical status, disease control, neurocognitive effects, and quality of life during follow-up in our department.

The purpose of the study is to improve the overall survival patients with newly diagnosed malignant brain tumors treated with stem cell radiation therapy and chemotherapy. The investigators will also measure how patients treated with this novel method of radiation therapy do over time in terms of disease control, potential neurocognitive side effects, overall function, and quality of life.

Description:

Even after optimal standard treatment, the outcome for patients suffering from glioblastoma (GB) is currently dismal, and temozolomide adds a modest survival benefit at high monetary cost and is accompanied by considerable toxicity. A possible explanation for the failure of radiotherapy to cure GB is the observation that glioma cells migrate widely into healthy bilateral brain tissue from one or more foci of origin. These isolated cells are not detected by current radiological techniques or even imaging and therefore usually not included into the target volume during radiotherapy. In this present study the investigators would like to test the hypothesis that the dose prescribed to the normal tissue stem cell niche in the adult brain will influence the effectiveness of radiotherapy for patients suffering from HGG/GB as these niches may serve as a harbor for radioresistant glioma stem cells, which are the only cells in a HGG believed to able to repopulate a tumor.

The hypothesis is based on previous reports showing that adult normal tissue stem cells reside in the lateral periventricular regions of the lateral ventricles and animal studies reporting that transformation of normal tissues stem cells but not differentiated cells lead to tumor formation. This unique anatomical pattern of the brain that clearly separates stem cell niches as a potential pool of cancer stem cell (CSC's) from differentiated tissue make this an ideal model system to study the impact of radiation dose given to these stem cell niches. Therefore, prospective, randomized clinical trials are needed to address the efficacy and toxicity of including the CSC-containing subventricular region as additional target volumes into treatment plans for patients suffering from HGG/GB. This intervention could dramatically improve the outcomes of patients suffering from progressive, relapsing disease despite our best efforts currently.

Intervention

Radiation:
• Stem Cell Radiotherapy (ScRT) and Temozolomide
Stem Cell Radiotherapy (ScRT) and Temozolomide: The postoperative surgical bed + edema + margin & the ipsilateral subventricular zone (contoured as a 5mm rim of tissue around the ipsilateral lateral ventricles) will be included within the initial target volume and treated to 46 Gy in 23 fractions. After 46 Gy, the conedown or boost volume (surgical cavity + margin) will be treated to a total of 60 Gy, with seven additional fractions of 2 Gy each (14Gy boost dose). Temozolomide will be administered continuously from day 1 of radiotherapy to the last day of radiation at a daily oral dose of 75 mg/m2. The drug will be administered orally on an empty stomach, the first dose to be given the night prior or morning of the first radiation fraction, and continued until the last radiation fraction is completed (including weekends and holidays).
