Abstract

卵巢恶性肿瘤的发病率及死亡率均较高。上皮性卵巢癌(epithelial ovarian cancer,EOC)占卵巢恶性肿瘤的85%-90%,其恶性程度高、病情发展迅速,仍然是妇科恶性肿瘤患者死亡的主要原因[1,2],由于其原发于盆腔深部,以前超声和糖链抗原125(CA125)检测是国内EOC常见的筛查手段[3],但超声诊断灵敏度以及特异度低,(CA)125在其他非卵巢恶性肿瘤及非肿瘤相关疾病中也有一定的阳性率,70%患者发现时已处于癌症晚期失去了最佳手术时机。最新研究显示,上皮性卵巢癌患者病死率仍然较高,5年生存率仅为40%-50%[4]。因其早期症状不明显,且进展迅速、易于播散等特点,通常确诊时大多数已进入中晚期阶段[5]。到目前为止,EOC的发病机制尚未研究透彻,近年来EOC的研究热点是分子机制的研究,并寻找其治疗EOC的方法。
