title: Behaviour of ovarian tumors of low malignant potential treated with conservative surgery.
abstract: OBJECTIVE
  Fertility-sparing surgery has been proposed for the treatment of borderline ovarian tumors. The aim of this study was to evaluate the outcome of patients submitted to cystectomy (CYS) compared with patients treated by unilateral salpingo-oophorectomy (USO) or bilateral salpingo-oophorectomy with/without total hysterectomy (radical surgery, RS).
  
  
  METHODS
  We reviewed retrospectively the data of patients treated in 3 institutions for borderline ovarian tumors. One hundred and sixty-eight patients underwent laparoscopic or laparotomic surgical treatment from 1985 to 2006. Tumor recurrence rate, disease-free survival and site of recurrences were evaluated. Specific prognostic factors, such as stage, histology, micropapillary subtype, exophytic tumor growth, intraoperative spillage, endosalpingiosis, staging procedures, and route of surgery were analysed.
  
  
  RESULTS
  Thirty-five patients underwent cystectomy, 50 unilateral salpingo-oopohorectomy, and 83 radical surgery. Twelve patients in the CYS group (34.3%), 10 in the USO group (20.0%), and 5 (6.0%) in RS group relapsed. Five-year progression-free survival (PFS) was 59.6%, 78.4%, and 93.5% in CYS, USO and RS groups, respectively. None of the relapsed patients died of disease.
  
  
  CONCLUSIONS
  Cystectomy is an effective surgical strategy for patients with borderline ovarian tumor. The higher risk of local relapses is not associated with a reduction in the overall survival. The procedure should be offered to young patients with bilateral tumors and to very young ones, considering the higher risk of local relapse.
