Outline of Final Research Achievements

The aim of this study was to investigate local control of in non-small round cell soft tissue sarcomas.The overall survival rates at 5 years were 85.7%.The local recurrence-free survival rates at 5 years were 89.8% (positive margin: 72.5%, margin of 2 mm or less: 60.6%). In the univariate analysis size, depth, histological grade and positive margin were significant unfavorable prognostic factors for local recurrence free survival. In multivariate analyses, we showed that positive margin and histological grade were significant independent predictors of local recurrence free survival.Positive margin and histological grade were important prognostic factors for local recurrence. Close margin (2 mm or less) in the longitudinal direction was associated with a high risk of local recurrence.The reach of the local treatment should be decided based on these factors.
