Targeted Local Therapy for Management of Intracranial High-Grade Gliomas
Abstract:
Systemic chemotherapy of malignant brain tumors has failed to achieve sufficient drug concentrations at the neoplasm site and frequently results in severe toxicities. Therefore, the local application of several anticancer agents, oncolytic viruses and vectors for gene therapy, immune-modifying preparations, and angiogenesis inhibitors has been investigated widely. Various modes of their administration were introduced, including intratumoral injections, implantation of reservoirs or pumps, convection-enhanced delivery, and use of nanocarriers, thermoreversible gels, microchips, and drug-loaded polymers. Many of these therapeutic approaches have shown promising results in management of high-grade gliomas.
Insights
Local therapies for malignant brain tumors offer better drug delivery and reduced toxicity compared to systemic chemotherapy. These innovative methods show promise for treating high-grade gliomas.
Area of Science:
- Oncology
- Neuroscience
- Pharmacology
Background:
- Systemic chemotherapy for malignant brain tumors has limitations, including insufficient drug concentration at the tumor site and significant systemic toxicities.
- These challenges necessitate the exploration of alternative therapeutic strategies for brain tumor treatment.
Purpose of the Study:
- To review and summarize various local therapeutic approaches for malignant brain tumors.
- To highlight the potential of these methods in improving treatment efficacy and reducing side effects.
Main Methods:
- Review of literature on local drug delivery systems for brain tumors.
- Analysis of different administration routes and therapeutic agents, including anticancer drugs, oncolytic viruses, gene therapy vectors, and immune modulators.
- Examination of novel delivery technologies such as nanocarriers, pumps, microchips, and drug-loaded polymers.
Main Results:
- Local application strategies can achieve higher drug concentrations directly at the tumor site.
- Various local administration methods, including intratumoral injections and convection-enhanced delivery, have been investigated.
- Emerging technologies like nanocarriers and drug-loaded polymers show promise for targeted delivery.
Conclusions:
- Local therapeutic strategies represent a promising advancement in managing malignant brain tumors, particularly high-grade gliomas.
- These approaches offer a potential solution to overcome the limitations of systemic chemotherapy.
- Further research and clinical translation of these localized treatments are warranted.
