BACKGROUND: @entity2698 is an uncommon soft tissue @entity242 . We sought to evaluate the long-term outcome of a consecutively treated @entity1 cohort with @entity2698 . METHODS: The study involved 36 adult @entity1 (older than 16 years) with @entity2698 treated at The University of Texas M. D. Anderson @entity5 Center between July 1975 and July 1995. Data on clinicopathologic parameters, surgical treatment, adjuvant therapy, disease recurrence, and survival were obtained from a review of medical records. RESULTS: The median follow-up was 57 months. Twenty-eight @entity1 (78%) underwent complete and potentially curative resection of their primary disease. Of the nine @entity1 (32%) who had local recurrences, four (57%) had @entity5 and three (43%) had @entity5 , but none had extremity @entity5 . Extremity @entity5 were associated with a significantly prolonged local recurrence-free survival compared to @entity5 at nonextremity anatomic sites (P <.05). Ten @entity1 had recurrences at distant sites. Of the 13 @entity1 who experienced any form of disease recurrence, four had recurrences after a disease-free interval of more than 5 years. The 5-year actuarial survival rate for the entire group of 36 @entity1 was 71%. Noncurative surgical treatment (P=.007) and development of distant metastatic disease (P=.013) were associated with shortened survival. CONCLUSION: Extended survival is common in @entity2698 @entity1 treated with curative intent. However, local and distant recurrences may occur after a prolonged disease-free interval, emphasizing the need for long-term follow-up. @entity3554 were associated with higher local recurrence rates; therefore, adjuvant therapies should be considered and evaluated for @entity5 at these sites.
