Summary
Surgery, with or without radiotherapy, effectively treated spinal aneurysmal bone cysts, preventing recurrence. Radiotherapy alone showed a higher recurrence rate, with some fatal outcomes in these spinal tumor cases.
Area of Science:
- Orthopedic Surgery
- Neurosurgery
- Pediatric Oncology
Background:
- Aneurysmal bone cysts (ABCs) are rare, benign, expansile bone lesions.
- Spinal ABCs can cause significant morbidity due to potential neurological compromise.
- Optimal treatment strategies for spinal ABCs remain under investigation.
Purpose of the Study:
- To analyze treatment outcomes for aneurysmal bone cysts of the spine.
- To evaluate the efficacy of surgery and radiotherapy in managing spinal ABCs.
- To assess the impact of treatment on neurological deficits and recurrence rates.
Main Methods:
- Retrospective analysis of twenty-two patients with spinal ABCs.
- Review of patient demographics, lesion site, symptoms, and radiographic findings.
- Comparison of treatment modalities: surgery alone, radiotherapy alone, and combined surgery and radiotherapy.
Main Results:
- Twelve patients presented with neurological deficits, all of whom recovered post-treatment.
- No recurrences were observed in patients treated with surgery (alone or combined with radiotherapy).
- Three of six patients treated with radiotherapy alone experienced local recurrence, with two fatal outcomes.
Conclusions:
- Surgical intervention, either alone or combined with radiotherapy, is highly effective in preventing recurrence of spinal ABCs.
- Radiotherapy alone is associated with a significant risk of local recurrence and potential mortality.
- Prompt treatment of spinal ABCs, especially in the presence of neurological deficits, leads to favorable recovery.
