Abstract

Objective: Borderline ovarian tumors (BOT) are characterized by atypical epithelial proliferation without stromal invasion and majority are diagnosed in women of reproductive age group desirous of fertility preservation.

Methods: A retrospective review of medical records of patients diagnosed with BOT and on regular follow up at the All India Institute of Medical Sciences New Delhi, during a nine-year study period from March 2014 to March 2023 was performed. Surgical treatment was classified as radical or fertility sparing surgery (FSS). Surgical staging was defined as complete, partial or un-staged.

Results: Median age of 91 women was 34 years. Follow up period ranged from 4 to 222 months (median 77 months). Among 68 premenopausal women, 31 (46 %) underwent radical surgery and FSS in 37 (54 %) cases. Median time to conception in 29 women with future fertility wishes was 13 months (range, 4 to38 m). Seven of 29 cases (29 %) required ovulation induction. The pregnancy rate was 82.7 % and live birth rate was 80 %. Eight cases (8.7 %) had a recurrence (7- un-staged, 1- partially staged) and median time to recur was 36 months. There was no significant difference in recurrence between cystectomy/oophorectomy. Ovary was the site of recurrence in all surgically salvaged cases except peritoneal cavity in 1 case with mortality. Relapse free survival at 5 and 10 years in FSS and radical surgery group were similar.

Conclusion: FSS is a safe procedure and should be considered in young patients desirous of future fertility along with a comprehensive peritoneal staging. Reproductive outcomes are excellent.
