An increased number of children and adolescents with ovarian tumors have been managed with ovarian-sparing surgery in the last few years. However, comprehensive data on fertility outcomes and local relapse are scarce. In this study, we systematically describe the contemporary outcomes of ovarian-sparing surgery, as reported in the literature.
Using PRISMA guidelines, we analyzed studies reporting ovarian-sparing techniques for ovarian tumors in children and adolescents. from 1980 to 2022. Reports with fewer than three patients, narrative reviews, and opinion articles were excluded. Statistical analysis was performed for dichotomous and continuous variables.
Of 283 articles screened, 16 papers (3057 patients) met inclusion criteria (15 retrospective/1 prospective) and were analyzed. The vast majority of studies had no long-term fertility follow-up data and direct comparison between ovarian-sparing surgery vs oophorectomy was reported in only a few studies. Ovarian sparing surgery was not associated with worse oncologic outcomes in terms of (i) tumour spillage or (ii) recurrence rates, and of key importance allowed a higher ovarian reserve at long term follow-up.
Ovarian-sparing surgery is a safe and feasible technique for benign tumors. Long-term outcome studies are needed to show efficacy and fertility preservation.
