Fertility-sparing surgery for patients with stage IC2 or IC3 epithelial ovarian carcinoma: any evidence of safety?
Investigate the overall survival of patients with stage IC2/IC3 epithelial ovarian carcinoma undergoing fertility-sparing surgery. Patients aged A total of 235 cases were identified; 105 (44.7%) patients underwent fertility-sparing surgery. There was no difference in overall survival between the fertility-sparing and radical surgery groups (p=0.37; 5- year overall survival rates 90.2% and 85%, respectively). After controlling for tumor grade and performance of lymphadenectomy, fertility-sparing surgery was not associated with worse overall survival (HR 1.22, 95% CI 0.56, 2.62). A systematic review identified 151 patients with stage IC2/IC3 disease who underwent fertility-sparing surgery. Cumulative relapse rate was 19.3% (n=29) while 12 (6.7%) deaths were reported. Median time to recurrence was 19 (range 1-128.5) months. Tumor recurrence involved the ovary exclusively in 42% (11/26) of patients, while 15% (4/26) had a lymph node, 35% (9/26) a pelvic/abdominal, and 8% (2/26) a distant tumor relapse. In a large cohort of patients with stage IC2/IC3 epithelial ovarian carcinoma, fertility-sparing surgery was not associated with worse overall survival. However, based on a literature review, relapse rate is approximately 20%.
