title: Long-term outcome in 87 patients with low-grade soft-tissue sarcoma.
abstract: OBJECTIVE
  To describe the long-term clinical outcome of patients with low-grade soft-tissue sarcoma and identify factors that may predict or determine their prognosis.
  
  
  METHODS
  Retrospective chart review with multivariate analysis.
  
  
  METHODS
  Large research hospital and referral center.
  
  
  METHODS
  All patients treated between 1975 and 1990 at the National Cancer Institute (Bethesda, Md) who had a confirmed diagnosis of low-grade soft-tissue sarcoma.
  
  
  METHODS
  Surgery and radiation therapy.
  
  
  METHODS
  Local recurrence and overall survival.
  
  
  RESULTS
  For patients with nonretroperitoneal lesions, overall survival was excellent, with a history of recurrence, a positive surgical margin, and an absence of adjuvant radiation therapy significantly associated with increased risks of local recurrence. Patients with retroperitoneal lesions not only had an increased risk of local recurrence, but significantly poorer overall survival.
  
  
  CONCLUSIONS
  Low-grade soft-tissue sarcomas are associated with excellent overall survival, especially those confined to nonretroperitoneal sites. The risk of local recurrence after resection with negative margins and/or adjuvant radiation therapy is very low and most recurrences can be controlled with further therapy.
