卵巢恶性肿瘤是妇科常见肿瘤 ,其死亡率在妇科恶性肿瘤中占首位[1 ] ,而且 ,近年来发病率有明显上升趋势[2 ] 。目前尚缺乏敏感及特异的实验诊断和监测方法。我们采用电化学发光法测定血清ＣＡ12 5含量 ,以探讨血清ＣＡ12 5对卵巢恶性肿瘤的诊断价值尤其早期诊断价值 ,现报道如 Ovarian cancer is a common gynecological cancer, the mortality rate in the gynecological malignancies in the first place [1], and, in recent years, a significant upward trend in the incidence [2]. At present, there is a lack of sensitive and specific experimental diagnosis and monitoring methods. We use the electrochemical luminescence determination of serum CA12 5 levels to explore the serum CA12 5 on the diagnosis of ovarian cancer in particular the early diagnosis of diagnostic value, is reported
