Introduction/Background This retrospective study aimed to evaluate the safety of ovarian cystectomy in patients with borderline ovarian tumors.

Methodology Patients with borderline ovarian tumors treated between August 2007 and August 2017 at our institution were divided into two groups according to the type of surgery: cystectomy and oophorectomy with or without salpingectomy. The cumulative disease recurrence was compared using Kaplan-Meier curves. Differences in surgical outcomes were also compared.

Results Of the 169 patients enrolled, 134 (79.3%) had an oophorectomy with or without salpingectomy and 35 (20.7%) had an ovarian cystectomy. Eight patients (4.7%) developed recurrence of disease: six (4.5%) patients in the oophorectomy group and two (5.7%) in the cystectomy group and one patient died. Median disease-free months were 30 months for oophorectomy patients and 40 months for cystectomy patients, while the two-year disease-free rate was 97.6% and 94.7%, respectively. DFS was not different between the groups (p=0.886). The surgical approach (minimally invasive surgery or laparotomy) was not associated with disease recurrence (p=0.881). None of the parameters increased risk of recurrence on univariate analysis.

Conclusion In conclusion, ovarian cystectomy can be considered a safe and effective option in young women who desire fertility preservation.
