子宫内膜癌卵巢转移危险因素的Meta分析

目的 系统评价子宫内膜癌(EC)卵巢转移的危险因素,为EC手术方式的制订及卵巢转移风险提供循证医学证据.方法 计算机检索PubMed、EMBase、Cochrane Library、万方全文数据库、中国知网(CNKI)、中国生物医学文摘数据库(CBM)关于EC卵巢转移危险因素的研究,检索时间从1990年1月1日至2016年9月1日.应用纽卡斯尔-渥太华量表(NOS)文献质量评价表的评价标准对纳入的文献进行质量评价.结果 纳入13篇文献,6 140例EC患者,发生卵巢转移344例(5.60％).Meta分析结果显示,共有9个危险因素,分别是深肌层漫润(OR=0.28,95％CI:0.21～0.39)、侵犯宫颈(OR=0.27,95％CI:0.16～0.45)、淋巴结受累(OR=0.21,95％CI:0.15～0.27)、输卵管受累(OR=0.05,95％CI:0.02～0.10)、非子宫内膜样腺癌(OR=0.32,95％CI:0.24～0.43)、低分化(OR=0.39,95％CI:0.31～0.50)、腹水细胞学检查阳性(OR=0.14,95％CI:0.09～0.20)、CA125水平高(OR=0.12,95％CI:0.08～0.19)、脉管癌栓(OR=0.34,95％CI:0.23～0.50),均差异有统计学意义(P＜0.05).而年龄、病灶部位、病灶直径大小、雌激素受体水平差异无统计学意义(P＞0.05).结论 深肌层浸润、侵犯宫颈、淋巴结受累、输卵管受累、非子宫内膜样腺癌、低分化、腹水细胞学检查阳性、高CA125水平、脉管癌栓是EC卵巢转移的危险因素.

Risk factors for ovarian metastasis in endometrial carcinoma:a Meta analysis

Objective To systematically evaluate the risk factors for ovarian metastasis of endometrial carcinoma(EC) to provide an evidence-based medicine basis for formulating the EC surgical mode and ovarian metastatic risk.Methods Studies about the risk factors for EC ovarian metastasis were retrieved by computer from the Pubmed,Embase,Cochrane Library,WanFang database,CNKI,China Biology Medicine(CBM) from Jan.1,1990 to Sep.1,2016.The quality evaluation of included literature was performed by using the Newcastle-Ottawa Scale(NOS).Results A total of 13 studies were included,involving 6 140 EC patients,of whom 344 cases(5.60％) had ovarian metastasis.The Meta analysis results showed that a total of 9 factors had statistical significance,which were deep myometrial infiltration(OR =0.28,95 ％ CI:0.21-0.39),cervical involvement (OR =0.27,95 ％ CI:0.16-0.45),lymph node involvement (OR =0.21,95 ％ CI:0.15-0.27),fallopian tube involvement (OR =0.05,95 ％ CI:0.02-0.10),non-endometrioid adenocarcinoma(OR=0.32,95％CI:0.24-0.43),low differentiation(OR=0.39,95％CI:0.31-0.50),positive ascites cytologic detection(OR=0.14,95％CI:0.09-0.20),high serum CA125 level(OR=0.12,95％CI:0.08-0.19) and lymphovascular cancer embolus(OR =0.34,95 ％ CI:0.23-0.50),the differences were statistically significant(P＜0.05).But the age,lesion location,lesion diameter and estrogenic receptor level had no statistical difference(P＞0.05).Conclusion Deep myometrial infiltration,cervical involvement,lymph node involvement,fallopian tube involvement,non-endometrioid adenocarcinoma,low differentiation and positive ascites cytologic detection,high CA125 level and lymphovascular cancer embolus are the risk factors for EC ovarian metastasis.
