OBJECTIVES: Pulmonary metastasectomy for sarcoma is a widely accepted practice. Nevertheless, no previous studies has been reported the outcomes following metastasectomy compared with chemotherapy for patients with resectable and isolated pulmonary metastases. Our aim is to compare these modalities for the subset of patients with resectable metastases. Furthermore, the outcomes for patients with unresectable lung metastases are reported. METHODS: Sarcoma patients with isolated lung metastases were identified and their computed axial tomography scans were reviewed by a thoracic surgeons' committee. Patients were divided into three groups: A: patients with resectable metastases treated with metastasectomy (n=29), B: patients with resectable metastases who received systemic therapy (n=17) and C: patients with unresectable metastases (n=25). Survival outcomes were plotted and compared through log-rank test for osteosarcoma and non-osteosarcoma patients. RESULTS: Seventy-one patients (32 with osteosarcoma and 39 with non-osteosarcoma) were eligible. Progression-free survival (PFS) was superior in patients who belonged to Group A compared with Groups B and C (8.0, 4.3 and 2.2 months, respectively, P=0.0002). Furthermore, overall survival (OS) was superior in patients who belonged to Group A compared with Groups B and C (39.6, 20.0 and 7.8 months, respectively, P<0.0001). A subanalysis for osteosarcoma patients showed superior PFS and OS for Group A vs B (median PFS 21.6 and 3.65 months, respectively, P=0.011 and median OS 34.0 and 12.4 months, respectively, P=0.0044). For non-osteosarcoma patients, there were no such significant survival differences between Groups A and B. Overall, patients who belonged to Group A had significantly lower mean percentage of their follow-up time spent admitted at hospital, and a trend towards lower requirements for home oxygen therapy. CONCLUSIONS: Pulmonary metastasectomy is associated with improved survival of osteosarcoma patients with resectable lung metastases. For non-osteosarcoma patients, the survival benefit of metastasectomy over chemotherapy is uncertain and warrants further evaluation. Patients with unresectable metastases have poor prognosis.
