{Abstract}: OBJECTIVE: To assess the ovarian cancer (OC) risk following endometrial cancer (EC) in patients who underwent ovarian preservation as part of the EC staging.
METHODS: With permission of the Surveillance, Epidemiology and End Results (SEER) program of the United States National Cancer Institute, clinicopathological information of women diagnosed with EC and following OC were analyzed. Incidence of OC and survival according to the surgical approach were studied. Primary analysis was conducted in women up to and including the age of 49 years.
RESULTS: A total of 116 patients up to the age of 49 years were diagnosed with EC and following OC. In this group of patients, no differences in incidence (IRR 0.9, CI 0.56-1.49, p = 0.66) or survival rates (p = 0.71) were found comparing ovarian preservation and bilateral salpingo-oophorectomy (BSO) performance. In an overall analysis of women diagnosed with EC and following OC at any age, incidence of OC did not differ between groups (IRR 1.07, CI 0.83-1.39, p = 0.59) yet when including patients older than 49 years old survival rates were shorter in ovarian preservation patients compared to patients with BSO performed as part of their EC treatment.
CONCLUSIONS: Ovarian preservation in EC patients under the age of 49 years may be considered safe, with no impact on OC incidence or survival, benefiting longer natural hormonal status.
