Safety and prognosis of ovarian preservationin young women with early-stage endometrial cancer / 基础医学与临床

ABSTRACT

Objective The aim of this study is to evaluate the safety and prognosis of ovarian preservation in young women with early-stage endometrial cancer.Methods Women≤45 years of age with stageⅠendometrial cancer recorded from Jan 2005 to Dec 2011 in Peking Union Medical College Hospital were examined.They were further divided into two groups ovarian preservation group and oophorectomy group.Clinical and pathological recording of these patients were compared.Results A total of 72 women, including 25 patients (34.7%) who had ovarian preservation, were identified.The ovarian preservation group was younger (P=0.007) and had a lower prevalence of lymphadenectomy (P0.05).Of seventy-two cases, five patients relapsed and all survived after a median follow-up time of 89 months (rang 7-131 months).The Kaplan-Meier curve and the log rank test showed no difference in recurrence-free survival (P=0.194).In Cox model analysis, ovarian preservation had no effect on recurrence-free survival(HR=3.08, 95% CI 0.54-18.44).Conclusions Ovarian preservation in young women with early-stage endometrial cancer is safe and has no negative effect on recurrence-free survival or overall survival.
