Background and objectives: Soft-tissue sarcomas (STS) represent a diverse histologic group of malignancies at risk for local and distant failure. We studied the impact of late (5 or more years) vs. early recurrence (less than 5 years) on subsequent outcome.
Methods: Four hundred sixty-eight patients with STS treated between 1962 and 1992 were evaluated for late (n = 39; 8%) or early (n = 253; 54%) recurrence. Clinical and pathologic factors were reviewed. Survival data were analyzed by the Kaplan-Meier method and the log-rank test.
Results: Of the 39 patients with a late recurrence (median follow-up 156 months), 18 patients had local recurrence, 7 patients developed distant recurrence, and 14 patients had local and distant recurrence. Thirty patients with late local and/or distant recurrence underwent complete or wide excision (n = 16), amputation (n = 4), or local resection (n = 10). The overall 5-year survival rate following late recurrence was 61%. The 5-year overall survival rate was statistically better for patients with a late local recurrence alone than for patients with distant failure, 94% vs. 36%, respectively (P = 0.003). Neither the site of the primary STS, age, primary margin status, nor histology had any effect on subsequent local or distant failure and subsequent survival.
Conclusions: These data suggest that an aggressive approach is appropriate in patients who present with late recurrence (more than 5 years) following treatment of the primary STS. Impressive survival rates can be achieved in the treatment of local recurrences.
