Summary
Pediatric solid tumors frequently relapse due to lung metastases. Complete surgical removal of lung metastases, alongside early detection and follow-up, can improve survival rates in children.
Area of Science:
- Pediatric Oncology
- Cancer Metastasis
- Thoracic Surgery
Context:
- Lung metastases are the primary cause of relapse in pediatric solid tumors.
- Understanding the patterns and outcomes of lung metastases in children is crucial for improving treatment strategies.
- This study analyzes lung metastatic cases in children treated between 1995 and 2005.
Purpose:
- To analyze lung metastatic cases in children with solid tumors.
- To evaluate the occurrence, treatment, and survival outcomes of lung metastases in pediatric cancer patients.
- To identify factors influencing survival in pediatric patients with lung metastases from solid tumors.
Summary:
- 26 pediatric lung metastatic cases were analyzed, with metastases present at diagnosis in 19.2% and occurring during/after treatment in 80.8%.
- Osteosarcoma and embryonal carcinoma were the most common primary tumors. Complete surgery showed a statistically significant positive impact on survival (p=0.02).
- 53.8% of children survived with a median survival of 8-120 months, while 46.2% died within 6-24 months.
Impact:
- Complete surgical resection of lung metastases, coupled with vigilant surveillance, can significantly prolong survival in pediatric cancer patients.
- The findings underscore the importance of active screening for lung metastases at diagnosis and throughout treatment.
- There is a critical need for novel therapeutic approaches to manage lung metastases in pediatric solid tumors.
