Summary
Central nervous system (CNS) metastases are a rare but serious complication in pediatric solid tumors. Early CNS imaging and interventions like surgery may improve outcomes for some patients, particularly those with sarcomas.
Area of Science:
- Pediatric Oncology
- Neuro-oncology
- Cancer Metastasis
Background:
- Central nervous system (CNS) metastases in pediatric solid tumors are infrequent but carry a poor prognosis.
- Understanding the patterns and outcomes of CNS metastases is crucial for improving patient care.
Purpose of the Study:
- To analyze the incidence, clinical presentation, patterns of spread, and outcomes of CNS metastases in pediatric solid tumors.
- To evaluate the potential benefit of specific therapies for CNS metastases in pediatric patients.
Main Methods:
- Retrospective analysis of 17 pediatric patients with solid tumors and CNS metastases treated over 21 years.
- Review of tumor types, diagnostic timing, localization patterns, treatment modalities, and survival data.
Main Results:
- CNS metastases occurred in 4.9% of pediatric solid tumor patients, most commonly in sarcomas and neuroblastomas.
- Metastases were often diagnosed at disease progression, frequently multifocal.
- Survival was poor (median 9 months), but sarcoma patients treated with radiotherapy or surgery showed improved survival.
Conclusions:
- CNS metastases in pediatric solid tumors are rare, with sarcomas and neuroblastomas being common primary sites.
- Therapeutic interventions like surgery and radiotherapy may benefit sarcoma patients with CNS metastases.
- Routine CNS imaging and molecular profiling should be considered for early detection and tailored treatment.
