Molecular and Clinical Insights into the Invasive Capacity of Glioblastoma Cells

الملخص EN

The invasive capacity of GBM is one of the key tumoral features associated with treatment resistance, recurrence, and poor overall survival.

The molecular machinery underlying GBM invasiveness comprises an intricate network of signaling pathways and interactions with the extracellular matrix and host cells.

Among them, PI3k/Akt, Wnt, Hedgehog, and NFkB play a crucial role in the cellular processes related to invasion.

A better understanding of these pathways could potentially help in developing new therapeutic approaches with better outcomes.

Nevertheless, despite significant advances made over the last decade on these molecular and cellular mechanisms, they have not been translated into the clinical practice.

Moreover, targeting the infiltrative tumor and its significance regarding outcome is still a major clinical challenge.

For instance, the pre- and intraoperative methods used to identify the infiltrative tumor are limited when trying to accurately define the tumor boundaries and the burden of tumor cells in the infiltrated parenchyma.

Besides, the impact of treating the infiltrative tumor remains unclear.

Here we aim to highlight the molecular and clinical hallmarks of invasion in GBM.
