Borderline ovarian tumors (BOT) are a unique type of epithelial neoplasms that mainly affect women of reproductive age. Due to their favorable course and high detection rate in the early stages, organ-preserving treatment is becoming a top priority, especially for patients planning a pregnancy.
Objective: To summarize and systematize current data on oncological safety, surgical approaches, reproductive outcomes, and the role of assisted reproductive technologies (ART) in patients with BOT who had a previous history of fertility-sparing treatment.
Materials and methods: The literature was searched using PubMed, Scopus, Web of Science, and CNKI databases. The review article included original studies with more than 20 patients. The studies provided the data on the types of surgery, disease recurrence and reproductive outcomes. The total sample included 4,586 patients.
Results: The lowest recurrence rate after fertility sparing surgery (FSS) was observed in ultrasound guided ovarian wedge resection (UGOWR) (0–3%); intermediate rate was observed in unilateral salpingo-oopherectomy (USO) (10–15%); maximum rate was noted in cystectomy (25–31%); micropapillary serous variant is associated with a recurrence risk of up to 45%. In the total sample of 4,586 patients, the pregnancy rate after FSS was 39–52%, the proportion of live births was up to 30%, miscarriages were ~11%, and premature births were 9%; ART was effective after thorough selection (8.6–20% recurrences, more often after cystectomy); full staging procedure reduces recurrence rate to 8–12% versus 30–40% without staging.
Conclusion: Organ-preserving interventions in BOT are oncologically justified if there is an individualized approach combined with complete surgical staging; UGOWR demonstrates the best profile of oncological safety and fertility preservation, and the use of ART is acceptable in specialized centers with controlled stimulation.
