Survival Outcome and Prognostic Factors After Pulmonary Metastasectomy in Sarcoma Patients: A 18-Year Experience at a Single High-volume Referral Center

Background: Metastatic sarcoma patients have a poor prognosis with 3-year survival rate of 25%. About 30% of them present isolated lung metastases. We aimed to analyze the clinical outcome of sarcoma patients undergoing pulmonary metastasectomy (PM) and prognostic factors associated with local control, disease-free, and overall survival (OS).
