RESUMO
Soft tissue sarcoma is a relatively rare disease from mesenchymal cells . Lung metastases occur in many of the patients with limb sarcoma . The aim of this study was the evaluation of lung metastasis due to limb osteogenic and soft tissue sarcoma in the hospitalized patients at Al-Zahra hospital in Isfahan between 1995 and 2008. This descriptive cross sectional study was done on the hospitalized patients at Al-Zahra hospital in Isfahan between 1995 and 2008. Lung metastases were evaluated by lung CT scan. The data were collected from the patients' dossier and their laboratory file. We used chi-square, fisher and T test, and SPSS software [v. 11] for analyzing the collected data. We evaluated 65 patients with limb sarcoma. Lung metastases were detected in 43.3% of the patients with osteogenic sarcoma and 11.4% of the patients with soft tissue sarcoma [p=0.005]. There were no relations between occurance of lung metastases and genders, the size of the primary tumor, the side of the stricken limb, and recurrence of the tumor. The incidence of lung metastasis in the patients with osteogenic sarcoma is more than the patients with soft tissue sarcoma. In view of the fact that the incidence of lung metastasis in the patients with osteogenic sarcoma is high, we suggest that these patients be evaluated for lung metastasis
