Metastatic epidural tumors in children

Area of Science:

• Pediatric Oncology
• Neurology
• Oncologic Emergencies

Background:

• Spinal cord compression is a rare but severe complication in pediatric malignancies.
• It can manifest as an initial sign of cancer or develop later in the disease course.

Purpose of the Study:

• To analyze the incidence, timing, and outcomes of spinal cord compression in children with cancer.
• To evaluate the impact of treatment, including laminectomy, on functional recovery.

Main Methods:

• Retrospective review of 81 pediatric patients with epidural spinal cord compression over 17 years.
• Analysis of patient demographics, primary cancer type, timing of compression, and treatment interventions.

Main Results:

• Spinal cord dysfunction presented initially in 29 patients with Ewing sarcoma, neuroblastoma, Hodgkin disease, and lymphoma.
• For osteosarcoma and rhabdomyosarcoma, compression often occurred later in the disease.
• Patients with paraplegia and complete sensory loss for ≥48 hours had poor ambulatory outcomes (4/22 achieved ambulation).
• Laminectomy did not significantly improve ambulatory rates in the studied groups.

Conclusions:

• Spinal cord compression is a critical complication in pediatric cancer with varied presentation timing based on tumor type.
• Prolonged severe neurological deficits portend a poor prognosis for ambulation.
• Surgical intervention (laminectomy) did not demonstrate a clear benefit for functional recovery in this cohort.
