Abstract

Glioblastoma (GBM) is the most common malignant brain tumor in adults with a 5-year survival of approximately 7%. The extensive heterogeneity between GBM patients (intertumor) and within the same tumor (intratumor) plays a fundamental role in treatment resistance and tumor recurrence. This work highlights the importance of dissecting GBM inter- and intra- tumor heterogeneity for the identification of new therapeutic approaches. Chapter 2 presents a comprehensive review on GBM inter- and intra- tumor heterogeneity and highlights the importance of fluorescence-guided multiple sampling for the dissection of GBM heterogeneity. Chapter 3 presents a study on the characterization of the tumor microenvironment in GBM patients and the identification of potential targets for treatment. Finally, chapter 4 focuses on a study to dissect the functional impairment of wt p53 in GBM by highlighting differences between wt and mutant TP53 GBM patients that could be relevant for the identification of potential therapeutic targets.
