ABSTRACT
Background and purpose: Alveolar soft part sarcoma (ASPS) is a rare malignant neoplasm characterized by slow growth and indolent behavior, and most of the patients had metastases in diagnoses. This study was to define clinical features and assess prognostic factors of ASTS. Methods: Between January 2003 and December 2008, there were 15 patients with ASTS who received treatment and were followed up in the Department of Orthopedic Ontology of Peking University People's Hospital. We retrospectively analyzed the clinical factors of the disease related to prognosis: gender, age, tumor size, primary tumor site, metastatic sites, local recurrence, the roles of postoperative radiotherapy and postoperative chemotherapy. Resnlts: At a follow-up from 7 to 76 months, only 2 patients had local recurrences after excision, but there was a high incidence of pulmonary metastases. Only 6 patients achieved disease free survival, 5 patients died of metastases or other complications. The five-year overall survival rates was 41.7%, and the median survival time was 42.0 months. Univariate analysis and Cox regression analysis revealed that tumor size, tumor primary site and metastases at diagnoses were prognostic factors, but not gender and age, Conclusion: Alveolar soft part sarcoma is a high grade malignant soft tissue neoplasm with frequent metastases to lung, bone or brain. Tumor size, primary tumor site and metastases at diagnoses are some of the prognostic factors. Chemotherapy or radiotherapy after surgery have no benefit to the survival in our analysis. Further prospective studies are needed to clarify the best strategy for the treatment of ASPS.
