Innovative drug delivery strategies for targeting glioblastoma: overcoming the challenges of the tumor microenvironment
Bibliographic record
Abstract
INTRODUCTION: Glioblastoma multiforme(GBM) presents a challenging endeavor in therapeutic management because of its highly aggressive tumor microenvironment(TME). This complex TME, characterized by hypoxia, nutrient deprivation, immunosuppression, stromal barriers, increased interstitial fluid pressure and the presence of the blood-brain barrier(BBB), frequently compromises the efficacy of promising therapeutic strategies. Consequently, a deeper understanding of the TME and the development of innovative methods to overcome its associated challenges are essential for improving treatment outcomes in GBM. AREAS COVERED: This review critically evaluates the major obstacles within the GBM TME, focusing on the biological and structural barriers that limit therapeutic delivery and efficacy. Novel approaches designed to address these barriers, including advanced formulation strategies and precise targeting mechanisms, are explored in detail. Additionally, the review highlights the potential of emerging technologies such as 3D-printed models, scaffolds, Robotics and artificial intelligence(AI) techniques and machine learning, in tackling TME- associated hurdles. EXPERT OPINION: The integration of these innovative methods presents a promising path for enhancing the specificity and efficacy of GBM therapies. By combining these advanced strategies, the potential for improving patient outcomes in GBM treatment can be significantly enhanced, offering hope for overcoming the limitations posed by the TME.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
