Introduction
Primary pulmonary sarcomas (PPS) are rare types of non-epithelial malignant tumors of the lungs (0.013–1.1% of all malignant lung tumors). The PPS can originate from mesenchymal elements of the bronchial wall, vessels or pulmonary stroma. Since the introduction of immunohistochemical and molecular diagnosis, a significant improvement in description and classification of sarcomas has been achieved. Nonetheless, sarcomas still remain a diagnostic and clinical problem.

Aim
To estimate factors which could have an influence on the overall survival (OS) and progression-free survival (PFS) of different types of radical operations (R0) for PPS.

Material and methods
Fourteen patients who underwent surgical radical treatment between 1994 and 2009 with a final diagnosis of PPS were analyzed.

Results
A group of 14 patients, treated with R0 operations (pneumonectomies, lobectomies, non-anatomical resections), were included in the analysis. Median OS of patients undergoing R0 operations was respectively: for pneumonectomy 7 months, lobectomy 20 months, non-anatomic resections 213 months. Patients subjected to non-anatomical resections had better prognosis than the others treated radically (p < 0.05); however, this group of patients had the most local recurrences (3 patients – 50%). Statistical analysis did not show the influence of prognostic factors characteristic of PPS and soft tissue sarcoma (STS) on OS in the types of surgery performed.

Conclusions
There are no unambiguous factors affecting OS and PFS of patients who have undergone anatomical and non-anatomical resections. A large number of local recurrences in non-anatomical operations may indicate that PPS spread like lung cancer.
