    • Abstract

    Background:
    Osteosarcoma is the malignant primary bone tumors which often develop in young people, 5-year overall survival in patients with pulmonary metastasis is around 50%. The objective of this study was to report the overall survival in a group of patients with metastatic osteosarcoma treated with surgical removal of the lung metastases.
    
    Methods:
    A retrospectic review from our data base revealed 9 patients performing 18 pulmonary metastasectomies between August 2005 and May 2016. The mean age was 18 years (range, 15-24) and 5 patients were male. All patients were treated with chemotherapy and oncologic resection of the primary tumor and thoracoscopic surgical removal of the lung metastases. 4 patients had bilateral lung operations, and only one lung metastasis was resected in three cases and the median number of metastases resected was 1.94.
    
    Results:
    The median overall survival was 34.9 months (range, 10-129). At follow up, 4 patients were dead with a median follow-up of 21.9 months. 5 patients were alive, and 4 patients were disease-free survivors, and 2 of 4 patients had only one pulmonary metastasis at the first lung matstasectomy.
    
    Conclusion:
    In selected patients, thoracoscopically pulmonary metastasectomy for osteosarcoma is safe, and may confer a good survival. Recurrent metastasis after resection confers a good prognosis.
