Abstract:
In order to grow, tissues require additional nutrients and oxygen as well as removal of waste products. Tumors achieve this by up-regulating angiogenic cytokines and/or down-regulating natural inhibitory proteins that allow neovascularization to proceed. Brain tumors continue to account for significant morbidity and mortality, in spite of significant advances in neurosurgical and radiation techniques and new chemotherapy combinations. As such, there is a real and immediate need for novel biologic therapies that can target these tumors. A number of new drugs that target different aspects of the angiogenic cascade have been identified and are now in clinical trials in children with primary brain tumors. In many of these pre-clinical and clinical studies, anti-angiogenic therapy has been well tolerated, has lacked many of the traditional toxicities of radiation and chemotherapy, does not require blood-brain barrier penetration, and targets a critical pathway in central nervous system tumor development. This review will discuss what angiogenesis is, how pediatric brain tumors regulate angiogenesis to obtain a vascular supply, what types of inhibitors are available, how different classes of inhibitors work, the types of resistance possible, how rapidly these inhibitors may work, and what surrogate markers of activity are available to follow response.
Insights
Novel biologic therapies targeting angiogenesis are needed for pediatric brain tumors. Anti-angiogenic drugs show promise, are well-tolerated, and avoid traditional toxicities, offering a new treatment avenue.
Area of Science:
- Oncology
- Vascular Biology
- Pediatric Medicine
Background:
- Tissues require nutrients and oxygen for growth, facilitated by blood vessel formation (angiogenesis).
- Tumors, including pediatric brain tumors, hijack angiogenesis for vascularization, contributing to morbidity and mortality.
- Existing treatments for pediatric brain tumors have limitations, necessitating novel therapeutic strategies.
Purpose of the Study:
- To review the role of angiogenesis in pediatric brain tumor development.
- To discuss current and emerging anti-angiogenic therapies targeting these tumors.
- To explore the mechanisms, efficacy, resistance, and monitoring of anti-angiogenic treatments.
Main Methods:
- Review of pre-clinical and clinical studies on angiogenesis inhibitors in pediatric brain tumors.
- Discussion of the molecular mechanisms underlying tumor angiogenesis.
- Analysis of clinical trial data for anti-angiogenic agents.
Main Results:
- Anti-angiogenic therapies target a critical pathway in central nervous system tumor development.
- These therapies have demonstrated good tolerability and fewer traditional toxicities compared to chemotherapy and radiation.
- Anti-angiogenic drugs do not require blood-brain barrier penetration, a key advantage for brain tumors.
Conclusions:
- Anti-angiogenic therapy represents a promising novel biologic approach for pediatric brain tumors.
- These therapies offer a potentially safer and targeted treatment option with a unique mechanism of action.
- Further research and clinical trials are essential to optimize the use of anti-angiogenic drugs in this population.
