title: Feasibility of ovarian cryopreservation in borderline ovarian tumours.
abstract: BACKGROUND
  Borderline ovarian tumours (BOT) do not exhibit overt stromal invasion and are less aggressive than invasive epithelial ovarian tumours. BOT also arise in younger patients than those who develop epithelial ovarian tumours. Our aim was to evaluate the feasibility of ovarian cryopreservation (OC) in patients treated for BOT.
  
  
  METHODS
  A retrospective study of data concerning young patients (less than 35 years of age) who underwent surgery for a BOT with OC planned during the surgical procedure.
  
  
  RESULTS
  Twenty-three patients, treated between January 2002 and February 2008, were initially selected but six of them were excluded from the present study (four because the tumour was malignant and two because it was benign). Finally, 17 patients were diagnosed as having BOT based on the frozen section analysis. In nine (53%) of these cases, OC was finally performed. In eight cases, OC was not performed; instead, in four cases a simple cystectomy was finally performed (one patient was in fact pregnant at the time of surgery), in one case malignant disease was found and in three (18%) patients OC was not technically feasible because no normal ovarian parenchyma was evident on gross inspection.
  
  
  CONCLUSIONS
  In patients treated for a BOT, OC was eventually feasible in 53% of patients in whom this procedure was initially planned. In 18%, this procedure was aborted because no macroscopic healthy ovarian tissue could be found.
