Radiotherapy in the Management of Paediatric Low-Grade Gliomas

Area of Science:

• Neuro-oncology
• Pediatric oncology
• Radiation oncology

Background:

• Paediatric low-grade gliomas (LGGs) are primary central nervous system tumors in children.
• Local tumor control is critical for managing childhood gliomas.
• Surgery is the primary treatment, with non-surgical options for inoperable cases.

Purpose of the Study:

• To review current management strategies for paediatric low-grade gliomas.
• To highlight the evolving role of radiotherapy and targeted therapies.
• To emphasize the need for comparative studies on modern radiotherapy and systemic treatments.

Main Methods:

• Review of current literature on paediatric low-grade glioma management.
• Discussion of surgical, chemotherapeutic, and radiotherapeutic approaches.
• Exploration of emerging targeted therapies and molecular genetic insights.

Main Results:

• Surgery is the mainstay for most paediatric LGGs.
• Radiotherapy is a standard salvage or primary treatment, with advanced techniques like proton therapy showing promise.
• Chemotherapy is increasingly used, and targeted therapies are under investigation.

Conclusions:

• Optimizing local tumor control is key in paediatric LGGs.
• Modern radiotherapy techniques may reduce long-term toxicities.
• Prospective studies are needed to compare radiotherapy efficacy and safety with systemic treatments, considering molecular patterns.
