1、血清CA125监测卵巢上皮性癌术后复发界值探讨郭娜,彭芝兰,楼江燕,刘辉,王平,张家文,尹如铁,王丹青作者单位:四川大学华西第二医院妇产科摘要:目的探讨CA125在监测卵巢上皮性癌术后复发的界值。方法冋顾性总结分析四川大学华西二院2005年1月至2009年12月收治的卵巢上皮性癌170例手术后患者,未复发纽135例,复发纽.35例,以绝经后休格检杏止帘的105例妇女及除卵巢恶性肿瘤之外的65例术后无复发的妇科恶性肿瘤患者作为对照组。以CA125值为5kU/L、10kU/L、15kU/L、20kU/L、25k
2、U/L、30kU/L、35kU/L分别作为界值,比较各界值对判断卵巢上皮性癌术后复发的敏感度、特并度。结果卵巢上皮性癌术后无复发患者、绝经后妇女及妇科恶性肿瘤术后患者CA125中位数值分别为7.5kU/L、8.4kU/L、6.9kU/L;均数土标准差分别为(8.3±3.6)kU/L、(9.1±4.2)kU/L、(7.3±2.6)kU/L。以15kU/L为界值判断复发,敏感度、特异度分别为74.3%、97.0%°结论以15kU/L为CA125界值配合影像学检杏监测卵巢上皮性癌术后病情变化,敏感度提高,能够早期
