Fertility-Sparing Surgery for Non-Epithelial Ovarian Malignancies: Ten-Year Retrospective Study of Oncological and Reproductive Outcomes

Abstract

Background/Objectives: Due to the rarity and histological heterogeneity of non-epithelial ovarian cancers (NEOCs), monitoring their reproductive and oncological outcomes is challenging. Therefore, this study aimed to investigate the oncological and reproductive outcomes of patients with NEOCs treated with fertility-sparing surgery over the past 10 years at our tertiary referral university clinic. Methods: This retrospective study included all the NEOC patients diagnosed and treated with fertility-sparing surgery from 2010 to 2019. The patient demographic and clinical characteristics; data regarding the treatment andthe clinical, laboratory, and imaging findings during follow-up; and disease recurrences were recorded. In this study, the recurrence-free survival and the overall survival were the oncological outcomes. The reproductive outcomes were assessed as attempting and achieving pregnancy. Results: This study included 39 patients. The most frequent NEOCs were granulosa cell tumors (53.8%). The majority of the tumors were in the IA or IC1 stage. The initial therapy was generally a unilateral salpingo-oophorectomy (30.8%). Adjuvant chemotherapy was received by 48.7% of the patients. An NEOC recurrence was registered in 25.6% of the patients, mostly during the first two postoperative years. The recurrence-free survival was 76.92%. A regression analysis showed that amore advanced stage of NEOC was the most important predictor of disease recurrence. The overall survival rate was 87.2%, with a mean time to an adverse outcome of 23.01 +/−10.68 months. The regression analysis showed that better survival depended mostly on not having disease recurrence. After treatment, ten patients tried to conceive and seven succeeded. All the children were in good condition upon birth. Conclusions: Fertility-sparing treatment for NEOCs was proven as a safe and successful option in terms of both oncological and reproductive outcomes. © 2025 by the authors.
