211例妇科盆腔肿块患者血清 CA125测定,以 CA125>65kU/L 为阳性标准,58例恶性肿块和153例良性肿块的 CA125阳性率分别为77.6%和20.4%.若以 CA125>188kU/L 为阳性标准,则阳性率分别为65.5%和6.5%。良、恶性肿块阳性率相差悬殊,故可考虑以 CA125>188kU/L 作为鉴别盆腔良、恶性肿块的参考标准。 The serum CA125 levels in 211 gynecologic pelvic masses were determined with CA125>65 kU/L as the positive standard. The positive rates of CA125 in 58 malignant tumors and 153 benign masses were 77.6% and 20.4%, respectively. If the CA125> 188 kU/L was positive For the standard, the positive rates were 65.5% and 6.5%, respectively. The difference in the positive rates of benign and malignant tumors is very different, so we can consider CA125> 188kU/L as the reference standard for distinguishing pelvic benign and malignant tumors.
