Live Births after in vitro Fertilization with Fertility-Sparing Surgery for Borderline Ovarian Tumors: A Case Series and Literature Review.

This is a case series reporting live births following in vitro fertilization (IVF) after fertility-sparing surgery in patients with borderline ovarian tumors (BOTs). Seventeen patients, in whom fertility-sparing surgery for BOTs followed by IVF was performed from July 1, 2011 to September 30, 2017, in our IVF center, were included. Here we retrospectively present their BOT characteristics and clinical outcomes of assisted reproduction technology (ART) and then discuss the literature on management of patients with BOTs after fertility-sparing surgery. The study sample of 17 patients started IVF-assisted reproduction within a median of 24 months after fertility-sparing surgery. Eight patients achieved live births after IVF followed by fresh or frozen-thawed embryo transfer, and one is currently pregnant after the second IVF treatment. Four of these 17 women experienced 6 recurrences of BOTs after IVF and delivery in a median of 29 months of follow-up. The literature reports a pooled estimate of 63.5% for pregnancy and 21.7% for recurrence of BOTs in patients with the same condition. Pregnancy outcomes of IVF in these women are usually better than those of generally infertile women. Moreover, our review of the literature suggests that ART has no negative impact on the prognosis of BOTs.
