Summary
Surgical resection of pulmonary metastases in pediatric oncology patients can lead to healing. A disease-free interval (DFI) over two years significantly improves survival rates after lung nodule resection.
Area of Science:
- Pediatric Oncology
- Thoracic Surgery
- Cancer Metastasis
Context:
- Pulmonary metastases affect 30-40% of cancer patients, sometimes exclusively in the lungs.
- Surgical resection of lung nodules offers a potential cure in select pediatric cases.
- This study reviews surgical interventions for pulmonary metastases in children.
Purpose:
- To evaluate surgical techniques and outcomes for pulmonary metastases in pediatric oncology patients.
- To determine prognostic factors influencing survival after pulmonary resection.
- To assess the role of thoracoscopy in managing lung metastases.
Summary:
- Between 1982-1997, 22 pediatric patients with pulmonary metastases underwent 16 thoracotomies.
- Primary tumors included Wilms tumors (23%) and bone tumors (67%).
- Survival was 54% overall, with 23% at 5 years; a disease-free interval (DFI) > 2 years correlated with 100% survival.
Impact:
- Pulmonary resection in selected pediatric cancer patients can improve survival outcomes.
- A disease-free interval exceeding two years is a critical factor for long-term survival.
- Thoracoscopy is a viable option for selected patients undergoing pulmonary metastasectomy.
