title: Retroperitoneal liposarcomas. Study of 10 cases.
abstract: BACKGROUND
  Retroperitoneal liposarcomas are unusual tumors. Their biological and clinical features different from other retroperitoneal sarcomas.
  
  
  OBJECTIVE
  To analyze our series of retroperitoneal liposarcomas.
  
  
  METHODS
  Retrospective study of 10 patients with retroperitoneal liposarcoma diagnosed in the last 16 years at our institution. Symptoms, diagnosis, treatment and prognosis were analyzed.
  
  
  RESULTS
  Radical resection was done in all cases. Postoperative mortality was 10%. Complementary treatment was considered in each patient. Recurrent disease occurred in 8 patients (14 recurrences), during follow up. In 42% of them recurrences were resected. Actuarial 5-year survival rate was 44%.
  
  
  CONCLUSIONS
  Poor prognosis of retroperitoneal liposarcoma is due to its high recurrence rate.
