Optic nerve and chiasm gliomas in children

Area of Science:

• Neuro-oncology
• Pediatric Ophthalmology
• Neurosurgery

Background:

• Optic nerve and chiasm gliomas are primary brain tumors affecting children.
• These tumors can lead to significant visual impairment, diencephalic disorders, and intracranial hypertension.

Purpose of the Study:

• To analyze the clinical characteristics, treatment modalities, and outcomes for pediatric optic nerve and chiasm gliomas.
• To identify the most effective treatment strategies for improving patient prognosis.

Main Methods:

• Retrospective analysis of 42 pediatric patients diagnosed with optic nerve and chiasm gliomas over 30 years.
• Evaluation of diagnostic imaging (skull X-rays, PEG, CT scans) and treatment interventions (surgery, radiotherapy).
• Follow-up assessment of treatment outcomes, focusing on the effectiveness of different therapeutic approaches.

Main Results:

• The study included 42 children, with symptom duration varying by age group.
• Common presenting symptoms included visual impairment and proptosis (73.8%).
• Combined surgical and radiation therapy demonstrated the most favorable outcomes among treated patients.

Conclusions:

• Pediatric optic nerve and chiasm gliomas require a multidisciplinary approach for optimal management.
• Combination therapy involving surgery and radiotherapy appears to be the most effective treatment strategy.
• Further research into optimizing treatment protocols for these rare pediatric brain tumors is warranted.
