Abstract
Purpose
Surgical procedures, histological subtypes, and surgical approaches are involved in the recurrence of borderline ovarian tumors (BOTs), but whether those three factors affect relapse remains controversial. This study aimed to explore the effects of surgical procedures, histological subtypes, and surgical approaches on the relapse and pregnancy rates of BOT after fertility-preserving surgery (FPS) according to the patients’ characteristics.
Methods
A systematic search of PubMed, Embase, and the Cochrane library was conducted from their inception to November 2018. Studies that investigated the impact of surgical procedures, histological subtypes, and surgical approaches on the relapse and pregnancy rates in patients with BOT after FPS were eligible. The pooled odds ratios (ORs) with the corresponding 95% confidence intervals (CIs) were calculated using the random-effects model.
Results
Thirty-five studies involving a total of 2921 patients with BOT after FPS were included. The pooled ORs indicated that the risk of relapse was significantly increased in patients who underwent unilateral cystectomy or with serous BOT. There was no significant difference between laparoscopy and laparotomy on the risk of relapse. Surgical procedures, histological subtypes, and surgical approaches did not influence pregnancy rates.
Conclusions
Patients who underwent unilateral cystectomy or with serous BOT presented an excess risk of relapse after FPS, but the surgical approach did not affect the risk of relapse. The pregnancy rate is not affected by surgical procedures, histological subtypes, and surgical approaches.
