Outcome of patients with curative-intent treatment for primary pulmonary sarcoma: Results from an international multicenter retrospective study

Objective: To evaluate outcome and prognostic factors of patients with primary pulmonary sarcoma (PPS) who underwent curative-intent surgery within multimodality treatment. Methods: An international, multicenter, retrospective study including patients with PPS was performed through a network of sarcoma experts. Data on demographics, staging, treatment, and outcomes were retrieved. Overall survival was calculated from the date of diagnosis. Prognostic factors were assessed using uni- and multivariate analysis. Results: = . 008) were independent prognostic factors for poor survival. Conclusions: In patients with curative-intent multimodal treatment for PPS, an encouraging 5-year survival rate of 49% can be achieved in expert centers. Independent prognostic factors may aid in selecting patients for curative treatment.
