Abstract
Pulmonary malignant fibrous histiocytoma (MFH) is very rare and it is worthy to study the clinical characteristics, treatment method and prognosis of primary pulmonary MFH. Fifteen patients with primary pulmonary MFH were reviewed retrospectively. There were 10 males and 5 females. Their ages were 56.2 years±14.0 years (20-72 years). MFH mainly manifested as cough, hemoptysis, fever, chest pain and breathlessness. The diameters of tumors were 8.3 cm±8.0 cm, ranged from 0.3 to 35 cm. All the patients received surgical operations, including 5 pneumonect-omy, 8 lobectomy and 2 exploration. The overall 1-, 3-and 5-year survival rate of 15 patients was 56.2%, 24.1% and 16.7% respectively. Incomplete surgical excision of tumor significantly influenced survival. Pulmonary MFH is a high-grade malignant tumor with poor prognosis, and surgery is the main treatment method.
