OBJECTIVE: To explore the prognostic factors associated with recurrence and survival in @entity1 with @entity242 . METHODS: A retrospective analysis was performed in 77 @entity1 who were affected by primary @entity242 and treated with surgery between January 1980 and December 2005. RESULTS: 57 cases developed local recurrence and 3 had @entity3 after surgery. The overall recurrence rate was 74%. Median time between initial surgery and recurrence was 14.8 months (range 3.2-99.6). There were 27 @entity1 who died of disease and 5 for other reasons. The median survival time was 42.5 months (range 3.6-180.4). The overall 5-year and 10-year survival rates were 61.7 and 43.9%,respectively. The 5-year and 10-year relapse-free survival rates were 22.7 and 16.8%, respectively. In univariate analysis, female sex (p = 0.047), @entity5 size < 15 cm (p = 0.045), complete @entity5 resection (p < 0.001), no adjacent visceral involvement (p = 0.012) and no local recurrence (p = 0.001) were found to have prognostic significance for a decreased risk of @entity5 -related mortality. When subjected to Cox multivariate analysis, the only factor found to decrease the risk of @entity5 -related mortality was complete @entity5 resection (p = 0.001). Incomplete @entity5 resection (p = 0.019) and high @entity5 grade (p = 0.042) were associated with an increased local recurrence rate. CONCLUSIONS: Complete surgical resection at the time of @entity5 presentation affords the best chance for local control and long-term survival. @entity1 with high-grade @entity5 present a significant risk of local relapse after surgery.
