title: [Treatment of retroperitoneal sarcoma].
abstract: OBJECTIVE
  To evaluate the results of treatment of retroperitoneal sarcomas.
  
  
  METHODS
  We evaluated clinical, diagnostic, surgical and histological parameters as well as adjuvant therapy and evolution in 15 patients with retroperitoneal sarcoma.
  
  
  RESULTS
  All patients presented abdominal tumors at diagnosis. Imaging revealed retroperitoneal origin. Complete surgical resection was carried out in seven patients (47%), reduction in size of tumor mass in five (33%) and exploratory laparotomy in three (20%). Histological analysis revealed 12 liposarcoma (80%), two leiomyosarcoma (13%) and one fibrosarcoma. Adjuvant therapy was given to two patients. Of the patients who underwent complete surgical resection, four survived without relapse (1, 2, 5 and 5 years respectively). With the other treatments, there were no survivals at 2 years. Adjuvant therapy did not influence survival.
  
  
  CONCLUSIONS
  Retroperitoneal sarcoma is diagnosed late. Prognosis is poor due to tumor relapse and only complete surgical removal produces a "cure".
