Official title
Functional Reorganization and Connectivity in Glioma Patients During the Therapeutic Trajectory
Overview
The goal of this observational study is to better understand how the brain changes during the treatment of glioma. In particular, the study looks at changes in important brain areas that are responsible for functions such as movement, language, or sensation, as well as the nerve fiber pathways that connect these areas. The main question this study aims to answer is: How do important brain areas and their connections adapt and reorganize over the course of glioma treatment? Patients with glioma will undergo repeated brain imaging examinations as part of their regular medical care. These images will be analyzed over time to observe changes in brain activity and structure during different stages of therapy. By studying these changes, researchers hope to gain new insights into the brain's ability to adapt (neuroplasticity) throughout the entire course of glioma treatment.
Primary outcome measures
- Treatment-related changes in BOLD signal and diffusion tensor imaging (DTI) outcomes across different stages of treatment. [Time frame: Day 0 (pre-neurosurgery baseline), Day 28 (post-surgery/pre-radiotherapy), and Day 126 to Day 140 (post-treatment)]
- Treatment-related changes in neurofunctional activation patterns and cerebral organizational and reorganization processes assessed by functional MRI and diffusion tensor imaging (DTI) at 1-year follow-up from treatment initiation. [Time frame: Day 0 (pre-neurosurgery baseline) and Day 365 (one-year follow-up)]
Secondary outcome measures (5)
- BOLD functional MRI signal change [Time frame: Day 0 (pre-neurosurgery baseline), Day 126-140 (post-treatment), Day 365 (one-year follow-up)]
- Fractional anisotropy (DTI) [Time frame: Day 0 (pre-neurosurgery baseline), Day 126-140 (post-treatment), Day 365 (one-year follow-up)]
- Mean diffusivity (DTI) [Time frame: Day 0, Day 126-140, Day 365]
- Cognitive performance score [Time frame: 0, Day 126-140, Day 365]
- Patient-reported quality of life score [Time frame: Day 0, Day 126-140, Day 365]
