Although the extracellular matrix (ECM) accounts for 20% of brain volume, collagen is present at low levels, mainly in perivascular regions. In the CNS, tissue repair occurs through gliosis, without abundant collagen production. In glioblastomas (GBM), collagen gene expression increases and the ECM is altered, influencing tumor adhesion, invasiveness, and recurrence. Collagen signatures may be prognostic markers in GBM patients. Studies demonstrate that microenvironmental reorganization, including collagen deposition, is crucial for GBM progression.
This study, involving 50 patients with GBM IDH-wild type, aims to evaluate the potential of ECM as a prognostic indicator. Through the analysis of tumor samples with stainings for ECM and type III collagen, the impact of ECM deposition and collagen architecture on patient survival will be assessed and a survival prediction model will be proposed using these factors. It is expected that the analysis of collagen deposition will allow the identification of patterns associated with survival in GBM patients and contribute to the understanding of the role of ECM in GBM progression as a potential prognostic biomarker.
