Borderline tumours of the ovary and fertility

Standard management of borderline ovarian tumours (BOT) is historically radical and based on hysterectomy, bilateral salpingo-oophorectomy and peritoneal staging. But, as 1/3 of BOTs are diagnosed in patients aged less than 40 years, treatments preserving fertility-potential (with preservation of the uterus and at least part of one ovary) has seen great developments in the last decade. Such treatments increase the rate of recurrences (between 15% and 35% depending on the type of conservative surgery), but without any impact on patient survival as most recurrent diseases are of the borderline type, easily curable and with excellent prognosis. The spontaneous pregnancy rate is nearly 50%. In case of persistent infertility, it seems that the use of ovarian induction or in vitro fertilization procedures could be proposed in selected cases. Follow-up is essential and based on clinical examination and routine ultrasonography. The interest of completion surgery (removal of the retained ovary) in patients who obtained pregnancy remains debated. in conclusion, conservative management of at least part of one ovary and uterus could be safely proposed at least to patients with early stage BOT, in order to preserve fertility-potential. The rate of recurrence is increased but without any impact on survival. (c) 2005 Elsevier Ltd. All rights reserved.
