Summary
Pediatric intramedullary spinal cord tumors are rare, with astrocytomas and ependymomas being most common. Advances in molecular markers and MRI improve diagnosis, surgical planning, and patient outcomes.
Area of Science:
- Pediatric neuro-oncology
- Spinal cord oncology
- Molecular diagnostics
Background:
- Intramedullary spinal cord tumors (ISCTs) are uncommon in children, accounting for less than 10% of pediatric central nervous system tumors.
- Low-grade astrocytomas and ependymomas are the predominant histological types.
- Clinical presentation often involves progressive symptoms like pain, motor deficits, or scoliosis, potentially delaying diagnosis.
Purpose of the Study:
- To review the current understanding of pediatric ISCTs.
- To highlight the role of modern diagnostic and prognostic markers.
- To outline current management strategies and outcomes.
Main Methods:
- Review of current literature on pediatric ISCTs.
- Emphasis on diagnostic modalities including MRI and diffusion tensor imaging.
- Discussion of therapeutic approaches, including maximal safe surgical resection, radiotherapy, and chemotherapy.
Main Results:
- Molecular markers (e.g., MAPK pathway alterations, H3K27M mutations, MYCN amplification) are crucial for refining diagnosis and prognosis.
- MRI, particularly diffusion tensor imaging, is vital for surgical planning.
- Maximal safe resection is the primary treatment modality.
Conclusions:
- Despite rarity, pediatric ISCTs require precise diagnosis and tailored management.
- Molecular markers and advanced imaging significantly improve diagnostic accuracy and prognostic assessment.
- While associated with potential morbidity, favorable long-term survival and functional outcomes are achievable for many pediatric patients with ISCTs.
