BACKGROUND: Soft tissue @entity242 (STSs) are rare @entity5 of embryogenic mesoderm origin. Primary thoracic STSs account for a small percentage of all STSs and limited published information is available. This study aimed to identify the prognostic factors for thoracic STSs and evaluate the disease's clinical outcomes. METHODS: The medical records of 109 @entity1 with thoracic STSs who were treated between 2003 and 2013 were retrospectively reviewed. @entity1 ' survival rates were analyzed and potential prognostic factors evaluated. RESULTS: The median follow-up period was 29 months (range: 1-121 months). STSs were most frequently localized on the chest wall (n = 42; 38.5%) and lungs (n = 42; 38.5%). The most common histological types were @entity1418 (n = 23; 21.1%), @entity1821 (n = 17; 15.6%), and @entity1822 (n = 16; 14.7%). The median survival time of all @entity1 was 40.3 months (95% confidence interval, 14.22-66.37 months), with one and five-year survival rates of 93.4% and 63.5%, respectively. Univariate analysis of all groups revealed that metastatic stage, unresectability, @entity5 diameter of >10   cm, @entity5 location other than the chest wall, and grade 3 diseases were predictable of poor survival. However, only grade 3 diseases and @entity5 location other than the chest wall were confirmed by multivariate analysis as poor prognostic factors. CONCLUSIONS: Primary thoracic STSs are rarely seen @entity5 . Our results indicated that @entity1 with low-grade @entity5 and those localized on the chest wall often experienced better survival outcomes.
