BACKGROUND: The majority of survival studies in patients with extremity soft tissue sarcoma have focused on early recurrence and mortality. There are few data addressing long-term follow-up and survival. OBJECTIVE: To analyze survival and recurrence in patients with extremity soft tissue sarcoma who survive for more than 5 years. METHODS: Patients who underwent treatment for primary tumors (July 1982 to July 1994) and were followed up for more than 5 years were the subject of study. Disease-specific and disease-free survival were determined actuarially. Significance was evaluated using log-rank testing for univariate analysis and Cox model stepwise regression for multivariate analysis. RESULTS: A total of 495 patients with primary extremity tumors were treated before July 1989 and eligible for 5-year follow-up. Of these, 282 have been followed up for more than 5 years (median follow-up, 84.4 months). Actuarial disease-specific survival of patients who survive for longer than 5 years was 79%+/-7% (+/-SEM) at 10 years, and of those who were metastasis free at 5 years was 91%+/-4% at 10 years. On univariate analysis, post-5-year disease-specific survival was influenced by positive microscopic margin and initial tumor size of 5 cm or greater. On multivariate analysis, post-5-year disease-specific survival was influenced only by positive margins. CONCLUSIONS: Based on these analyses, 21% of patients with primary extremity sarcoma who survive for 5 years will die of disease within ...
