[摘要] 目的：探讨血清CA125、CA199联合多普勒超声血流显像在早期卵巢上皮性恶性肿瘤诊断中的价值。方法：对2006年1月～2008年12月我院的102例卵巢上皮性肿瘤患者及42例对照组妇女分别进行血清CA125、CA199及多普勒超声检测，并分别以血清CA125>35 kU/L、CA125>100 kU/L，CA199>37 kU/L、CA199>70 kU/L，阻力指数(RI)<0.5、RI<0.6作为阳性结果，比较各种指标对卵巢上皮性恶性肿瘤预测的敏感性、特异性、阳性预测值和阴性预测值。结果：卵巢上皮性恶性肿瘤患者血清CA125、CA199水平明显高于对照组和良性肿瘤组，而良性肿瘤组和对照组间无显著性差异(P>0.05)。多普勒血流显像：恶性肿瘤组RI显著低于良性肿瘤组。单独应用CA125>100 kU/L敏感性为78.4%，特异性为88.4%，单独应用CA199>70 kU/L敏感性为49.0%，特异性为86.0%。多普勒超声(RI<0.5)联合上述两种血清学指标，敏感性为94.2%，特异性为95.3%。结论：血清CA125、CA199联合多普勒超声血流显像可明显提高卵巢上皮性恶性肿瘤诊断的敏感性和特异性。

[Abstract] Objective: To investigate the diagnostic value of serum CA125 and CA199 combined with Doppler ultrasound flow imaging in the early epithelial ovarian m alignancies. Methods: From January 2006 to December 2008, 102 cases of epithelial ovarian tumor patients and 42 cases of control group women in our hospital were assessed serum CA125, CA199 and Doppler ultrasonic testing. The levels of serum CA125>35 kU/L, CA125>100 kU/L; CA199>37 kU/L, CA199>70 kU/L; resistance index (RI) <0.5, RI <0.6 were considered as positive results, and the sensitivity, specificity, positive predictive value and negative predictive value of each index for predicting epithelial ovarian tumor were compared. Results: The levels in patients with epithelial ovarian m alignancies of serum CA125, CA199 were significantly higher than the control and benign group, while the difference between the benign group and control group was not significant (P>0.05). As to Doppler flow imaging, RI m alignant group was significantly lower than benign group ......
