目的系统评价系统性淋巴结清扫术(SL)治疗卵巢癌患者的预后效果和安全性。方法计算机检索PubMed、The Cochrane Library、Web of Science、CNKI、WanFang Data和CBM数据库,搜集SL治疗卵巢癌患者的随机对照试验(RCT)与队列研究,检索时限均从建库至2020年12月16日。由6名研究者独立筛选文献、提取资料并评价纳入研究的偏倚风险后,采用RevMan 5.4软件进行Meta分析。结果最终纳入5篇RCT和23篇队列研究,包括6166例患者。Meta分析结果显示:SL组与非系统性淋巴结清扫术(NSL)组卵巢癌患者的3年生存率、5年生存率、3年无进展生存率及5年无进展生存率的差异均无统计学意义。亚组分析结果显示,盆腔与腹主动脉旁淋巴结清扫术联合大网膜切除患者的预后较好。结论当前证据显示,SL对卵巢癌患者生存率和无进展生存率均无显著影响。受纳入研究数量和质量的限制,上述结论尚待更多高质量研究予以验证。
