目的:探讨那不勒斯预后评分(Naples prognostic score,NPS)在国际妇产科联盟(International Federation of Gynecology and Obstetrics,FIGO)分期Ⅰ~Ⅱ期宫颈癌患者术后复发和转移的预测价值。方法:回顾性收集186例FIGOⅠ~Ⅱ期宫颈癌患...目的:探讨那不勒斯预后评分(Naples prognostic score,NPS)在国际妇产科联盟(International Federation of Gynecology and Obstetrics,FIGO)分期Ⅰ~Ⅱ期宫颈癌患者术后复发和转移的预测价值。方法:回顾性收集186例FIGOⅠ~Ⅱ期宫颈癌患者的临床资料,根据NPS分为低危组(0分)、中危组(1~2分)和高危组(3~4分),比较各组间临床特征的差异。根据患者是否复发和转移分为无复发转移组(147例)和复发转移组(39例),比较2组患者的临床特征差异。采用COX回归分析患者复发转移的影响因素,采用Kaplan-Meier法比较不同NPS患者的无病生存期(disease free survival,DFS)。结果:NPS低危、中危和高危组白蛋白、中性粒细胞-淋巴细胞比值(neutrophil-lymphocyte ratio,NLR),淋巴细胞-单核细胞比值(lymphocyte-monocyte ratio,LMR)、分化程度和宫旁浸润比例比较,差异均有统计学意义(均P<0.05)。COX回归分析结果显示,NPS是宫颈癌患者复发转移的独立预后因素(HR_(高危vs.低危)=14.304,95%CI:3.214~63.656,P<0.001)。亚组分析结果显示,鳞癌患者NPS高危组的DFS明显低于中危组和低危组(Log-rankχ^(2)=23.267,P<0.001);FIGO分期Ⅰ期和Ⅱ期患者NPS高危组的DFS明显低于中危组和低危组(Log-rankχ^(2)分别为15.760和8.294,P<0.05)。结论:NPS是FIGO分期Ⅰ~Ⅱ期宫颈癌患者术后复发转移的独立影响因素,NPS较高的患者DFS相对较短。展开更多
