Management, prognosis and reproductive outcomes of borderline ovarian tumor relapse during pregnancy: from diagnosis to potential treatment options.

Background: fertility sparing surgery is the first option for treatment of childbearing age women affected by borderline ovarian tumor (BOT). This review put in evidence the benefits and the risks of conservative surgery procedure. Moreover, the literature review is aimed to analyze the possibility of fertility sparing surgery in BOTs and to define a standard treatment in the management of this pathology during pregnancy.

Methods: systematic analysis of the relevant literature for fertility sparing during pregnancy for BOT, accessed through MEDLINE (1982-2015), bibliographies, and interactions with investigators. The data were assimilated into a rigorous and objective contemporary description, enriched by prospective, controlled, and evidence-based studies.

Results: there are not many studies about BOT during pregnancy. It can reasonably assumed that after the diagnosis of a suspected BOT during the third trimester of pregnancy, an attitude of close surveillance could be adopted. To the best of our knowledge, we report the only case in literature focused about the treatment and management of borderline ovarian tumor relapse detected during pregnancy.

Conclusion: basing on our experience and on literature reported, the conservative management of BOT during gestation up to delivery could be considered feasible. The conservative debulking surgery should be performed at the time of cesarean section in a third referral center for gynecologic oncology.
