胶质母细胞瘤治疗耐药机制与近期进展

High-grade central nervous system cancers incur a significant burden of care on society. The combination of therapeutic resistance and high mortality makes it both a challenging target and a devastating diagnosis. Of these, one in two is characterized as glioblastoma (GBM) with a median survival rate of only 13.

5 months with the current standard of therapy. Modern interventions, such as PD-1 and CTLA-4 checkpoint inhibition and autologous CAR T cell delivery, remain stymied by both the difficult nature of drug delivery to the brain and the inherent immunosuppressive tumor microenvironment.

However, recent advances in the characterization of GBM have unveiled promising new therapeutic avenues aiming to target and eliminate the tumor. In this review, we summarize the mechanisms through which GBM is initiated, localized, and eludes therapy responses and provide an update on recent advances made within this therapeutic space to overcome GBM-mediated immunosuppression.

We also discuss the challenges with current and next generational treatment strategies before finally exploring the landscape of potential future therapeutic targets.
