年轻早期子宫内膜癌患者保留卵巢的安全性及预后

目的探讨年轻的I期子宫内膜癌患者保留卵巢的安全性及预后。方法回顾性分析北京协和医院2005年1月至2011年12月间接受手术治疗的年龄≤45岁的I期子宫内膜癌患者的临床病理资料。根据术中是否保留卵巢分为保留卵巢组和切除卵巢组,比较分析两组的临床病理特征及预后。结果研究共纳入患者72例,其中保留卵巢组25例(34.7%),切除卵巢组47例(65.3%)。保留卵巢组患者与切除卵巢组患者相比更年轻(P=0.007),并且接受淋巴结切除的比例明显低于保留卵巢组患者(P0.001)。两组患者在分期、肿瘤分级、肌层浸润深度以及术后辅助治疗方面均无统计学差异(P0.05)。72例患者的中位随诊时间为89个月(7~131月),共有5例患者复发,没有患者死亡。Kaplan-Meier生存曲线及log rank检验显示两组的无复发生存时间无差异(P=0.194)。COX风险回归分析发现保留卵巢对无复发生存期无影响(HR=3.08,95%CI 0.54~18.44)。结论年轻的早期子宫内膜癌患者保留卵巢是安全的,对患者的无复发生存时间无显著影响。

Safety and prognosis of ovarian preservationin young women with early-stage endometrial cancer

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 (P<0.001).While there were no significant difference in stage, tumor grade, the invasion depth of myometrium and adjuvant treatment between two groups (all P>0.05).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.
