The current gold standard for GBM treatment, known as the Stupp protocol, includes maximal safe surgical resection followed by radiotherapy and temozolomide chemotherapy. Despite extending survival modestly, this regimen is associated with significant side effects and limited efficacy, resulting in a median survival (MS) of 15 months and a 5-year survival rate of only 7%. A major challenge in GBM treatment is the blood-brain barrier (BBB), which restricts the penetration of therapeutic agents into the brain, thereby limiting the effectiveness of systemic therapies. To address these limitations, this systematic review and meta-analysis investigated the effectiveness of injectable local drug delivery systems (DDS) compared to systemic DDS in murine GBM models. This study aimed to provide robust evidence supporting the potential benefits of injectable local DDS for GBM treatment.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A comprehensive literature search was conducted using PubMed, Embase, and ScienceDirect databases. The studies included were original research on local DDS of anticancer agents compared to systemic DDS in orthotopic GBM tumor models. The data extraction process included information on survival rates, tumor growth, and other relevant outcomes. Statistical analysis was performed using Review Manager 5.4, employing a random-effects model to calculate the pooled mean difference (MD) in survival time between local and systemic DDS.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Out of 1341 records, six studies met the inclusion criteria, totaling 129 murine models. The meta-analysis revealed that local injection of DDS significantly improved the MS compared to systemic administration (MD = 2.76; 95% confidence interval, 0.43-5.09; &lt;i&gt;P&lt;/i&gt; = 0.03; I&lt;sup&gt;2&lt;/sup&gt; = 93%). The local injection of the DDS bypassed the BBB, achieving higher local drug concentrations and sustained release at the tumor site, leading to enhanced therapeutic efficacy and reduced systemic toxicity.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;This systematic review and meta-analysis provide compelling evidence that local injection of DDS significantly improves survival in GBM models compared with systemic therapies. These findings highlight the potential of local DDS to overcome the challenges posed by the BBB and deliver higher concentrations of therapeutic agents directly to the tumor site. However, further research is needed to validate these findings in human clinical trials and refine DDS formulations. Future research should focus on developing DDS formulations capable of delivering multiple therapeutic agents simultaneously, addressing the experimental variability in preclinical models, and conducting rigorous clinical trials to evaluate the safety and efficacy of local DDS in human patients.
