The safety of fertility and ipsilateral ovary procedures for borderline ovarian tumors

Abstract

Objective: To explore the optimal treatment options for women with borderline ovarian tumors (BOTs). Materials and Methods: The medical records of consecutive patients with BOTs in two academic institutions were retrospectively collected. The pertinent data, including clinicopathological characteristics and, treatment and prognostic information were evaluated. Results: A total of 281 cases of BOTs were included in this analysis. For the entire series, the 5- year disease-free survival (DFS) and overall survival (OS) rates were 91.8% and 98.5%, respectively. In the multivariate analysis, reservation of the ipsilateral ovary (HR: 0.104 [95% CI, 0.036-0.304], p = 0.000) and FIGO stage II-III (HR: 6.811 [95% CI, 2.700-17.181], p = 0.000) were the independent risk factors for recurrence. Ovarian surface involvement (HR: 64.996 [95% CI, 4.054-1041.941], p = 0.003) was the only independent prognostic factor for OS. Lymphadenectomy and adjunct chemotherapy had no significant impact on patients' recurrence and survival (recurrence: p = 0.332 and 0.290, respectively, survival: p = 0.896 and 0.216, respectively). Conclusions: Fertility-sparing surgery with healthy ovarian preservation seems safe and feasible for young women who prefer fertility-sparing treatment. Ovarian cystectomy to conserve the affected ovary/ovaries without ovarian surface involvement may be cautiously performed under fully informed consent for young women with bilateral BOTs who strongly prefer fertility-sparing treatment and have no evidence of infertility. However, long-term follow-up is necessary due to the relapse susceptibility of the ovary.
