Image-Based Quantitative Assessment of Acute Radiation-Induced Changes in Glioma
연구 개요
상세 설명
Once eligibility criteria have been assessed and the informed consent is obtained, participants will undergo a screening process to further ensure eligibility. Screening prior to registration will comprise a review of pathology reports, postoperative magnetic resonance Imaging (MRI) images, operative reports, and medical history; general physical and neurologic exams; routine blood work; and urine pregnancy test for women of childbearing age.
The study is intended to evaluate the response of radiation treatment (RT). The consent process will be performed between the surgery and the start of RT. RT will be prescribed as per the discretion of the treating radiation oncologist as per the University of Alabama at Birmingham Department of Radiation Oncology treatment protocol in combination with temozolomide.
MRIs will be obtained before start of RT, after completion of 20 +/- 4 Gy. after completion of 40+/- 4 Gy and after the entire radiation treatment. Conventional MRIs including perfusion sequences and whole brain spectroscopy will be performed as a part of the research study. The data obtained from this research studies will not be used for clinical management.
Volumes of the enhancing component, non enhancing component, choline/N-acetyl aspartate (Cho/NAA) will be measure before, during and after RT as described before. Cerebral blood volume (CBV) of the tumor will also be calculated from perfusion imaging at each time point. Apparent diffusion co-efficient (ADC) of the tumor will be calculated from the diffusion imaging.
All the patients will be followed up with imaging and will be treated as per the standard of care. Patients will return for clinical evaluation and standard of care imaging approximately 4 weeks from the completion of the radiation therapy. After that, all the patients will be treated with standard of care maintenance temozolomide therapy and will return every 2-3 months for clinical evaluation and standard of care imaging.
At the time of recurrence, the recurrence site will be assessed and will be compared with the imaging parameters obtained during radiation treatment. Time to recurrence will also be calculated and will be correlated with the imaging parameters.

실험적: Chemoradiation with MRI assessment
This study has only one arm.
The eligible subjects will receive standard of care fractionated radiation therapy along with concomitant temozolomide, which will NOT be changed based on the MRI scans obtained as a part of this study.
There is no control or sham group.
|
Standard of care fractionated radiation therapy will be given to the tumor.
Standard of care temozolomide will be given along with radiation therapy
다른 이름들:
Four MRI scan will be performed according to the protocol.
The first one will be obtained before start of radiation therapy, the second MRI will be obtained after completion of 20 +/- 4 Gy, the third MRI will be obtained after completion of 40 +/- 4 Gy, and the final MRI will be obtained after completion of the radiation therapy.
