Retrospective analysis of pulmonary sarcoma and blastoma with review of literatures

Abstract

Objective: To explore the clinical characteristics, diagnosis and treatment of pulmonary sarcoma and blastoma. Methods: Seven cases of pulmonary sarcoma (including 1 case of pulmonary carcinosarcoma, 1 case of pulmonary malignant fibroneuroma, 1 case of pulmonary malignant fibrous tissue tumor and 1 case of pulmonary blastoma from August 1995 to June 2002 in our hospital) were retrospectively summarized the histological characteristics, clinical features, diagnosis and treatment. Results: Pulmonary sarcoma and blastoma both are rare malignant tumors and can be easily misdiagnosed or mistreated. The main symptoms of both diseases are cough and expectoration. X ray or CT shows node or focus in lung. They both are diagnosed by histological pathology. Because the symptoms of these diseases are not typical, it is difficult for patients to be diagnosed without pathology. Conclusion: These two kinds of diseases are often easy to be misdiagnosed. Early diagnosis and treatment are important to improve the efficiency of treatment. Surgical resection is the best method of treatment, and it is important to combine with chemotherapy and radiation treatment.
