| Summary: | OBJECTIVES
This systematic review evaluates fertility-preserving surgery (FPS) outcomes in borderline ovarian tumours (BOTs), focusing on reproductive success and oncologic safety.
METHODOLOGY
We systematically searched PubMed, MEDLINE, ScienceDirect, Google Scholar, the Cochrane Library, and ResearchGate (through September 14, 2024) using the terms "borderline ovarian tumour," "fertility-preserving surgery," and "reproductive outcome." From 2,288 initial records, we identified 10 high-quality (Newcastle-Ottawa Scale score ≥7) retrospective cohort studies (January 2019- September 2024) that met our eligibility criteria. The included English-language studies evaluated reproductive-aged women (14-49 years) with borderline ovarian tumours undergoing fertility-sparing surgery (cystectomy/USO). After excluding case reports, reviews, non-peer-reviewed articles, and duplicate publications, two reviewers independently extracted data, resolving discrepancies through consensus. We conducted this systematic review in accordance with the PRISMA guidelines, with registration on Prospero (Id: Crd420251042984).
RESULTS
Among 1051 patients, pooled pregnancy rates ranged from 42.1% to 57.1%. Live birth rates varied widely (23-67%). Recurrence rates differed significantly by surgical approach: 24.1–33.3% after cystectomy versus 2.5-7.7% after USO. High-risk subgroups (advanced-stage/micropapillary histology) had recurrence rates up to 70.8%. Complete surgical staging reduced relapse risk by 21%, and ART did not increase recurrence. Bilateral cystectomy and USO + contralateral cystectomy showed comparable fertility outcomes. Malignant transformation was rare (0–20%), with no impact on overall 5-year survival (97–100%).
CONCLUSION
FPS provides reasonable reproductive outcomes but requires careful patient selection due to higher cystectomy-associated recurrence. Complete staging and histologic assessment are crucial. Until stronger evidence exists, USO with complete staging represents the most balanced option. Study limitations include retrospective designs and heterogeneous follow-up. Prospective trials with standardised protocols and long-term monitoring (at least 10 years) are needed.
