title: The effect of hysterectomy on survival of patients with borderline ovarian tumors.
abstract: OBJECTIVE
  The classically recommended surgical treatment of borderline ovarian tumors (BOTs) includes hysterectomy in addition to bilateral adnexectomy. Possible reasons for hysterectomy might be a high frequency of uterine involvement and its favorable effect on survival. The purpose of the present study was to assess the frequency of uterine involvement in patients with BOTs and the effect of hysterectomy on survival.
  
  
  METHODS
  All incident cases of histological confirmed BOTs diagnosed in Israeli Jewish women between March 1 1994 and June 30 1999, were identified. Clinical and pathological characteristics were abstracted from medical records. Patients with tumors grossly confined to the ovaries (apparently stage I) were considered to have had surgical staging when at least hysterectomy, bilateral salpingooophorectomy, omentectomy and pelvic lymph node sampling were done.
  
  
  RESULTS
  The study group comprised 225 patients. Hysterectomy was performed in 147 (65.31%) patients and uterine involvement was present in only 3 (2.0%) of them. The 13 year survival of the total group of patients was 85.8% and of those in apparent stage I, 88.5%. Among patients with tumors apparently confined to the ovaries, no significant survival difference was observed between unstaged and surgically staged patients. There was also no survival difference between the overall staged and unstaged patients and between patients in stages II-III who did and did not undergo hysterectomy.
  
  
  CONCLUSIONS
  Our data indicate that the rate of uterine involvement in BOT is low and that hysterectomy does not favorably affect survival. The necessity of hysterectomy in BOT patients is questioned.
