Optic nerve and chiasm gliomas in children
Insights
This study on pediatric optic nerve and chiasm gliomas found that combined surgery and radiotherapy yielded the best outcomes for children with these brain tumors.
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.
Abstract:
In a 30 years period, 42 children were admitted for optic nerve and chiasm gliomas; 20 patients aged less than 5 years and 22 between 6 and 16 years. Duration of symptoms ranged from 13.15 months in children aged less than 5 years, to 10.18 months in patients aged more than 6. Onset of symptoms were characterized by visual impairment and/or proptosis in 73.8%, diencephalic disorders in 16.6% and intracranial hypertension in 9.5%. All patients underwent skull X-rays; 31 had a PEG taken and 12 a CT scan. Surgery was prompted in 27 patients, 2 of which died in postoperative course. Radiotherapy was the treatment of choice in the other 15 patients, 40 patients were followed up: the best results were obtained in the group of patients operated on and irradiated.
