Extraskeletal myxoid chondrosarcoma: Clinical features and overall survival

Abstract

As a rare soft tissue sarcoma, many of the presenting features and survival outcomes of extraskeletal myxoid chondrosarcoma remain poorly defined due to the limited prevalence of this disease. The findings of this study suggest the overall survival may be worse than previously reported, and poor prognostic factors are those associated with worse survival in other soft tissue sarcomas, including high histologic grade, older age, larger tumor size, and lack of wide resection. Radiation and chemotherapy did not demonstrably improve survival for patients with localized or metastatic disease.
