【摘要】 本文对12例肺癌合并胸腔积液及12例结核性渗出性胸膜炎患者进行了胸水及血浆癌胚抗原(CEA)测定,结果显示肺癌患者胸水及血浆CEA均显著高于结核性胸膜炎患者(P<0.01)。肺癌患者中多数(8/12)胸水CEA>20ng/ml,虽有4例患者胸水CEA<10ng/ml,但其胸水CEA为血浆CEA的两倍或以上,提示测定胸水CEA及其与血浆CEA的比值有助于鉴别良恶性胸腔积液。更多还原

【Abstract】 Pleural effusion CEA and plasma CEA were detected in 12 cases of lung cancer with malig- nant pleural effusion and 12 cases of tuberculous pleural with effusion.The two kinds of CEA lev- els were significantly increased in patients with lung cancer(P<0.01).Effusion CEA level was above 20ng/ml during most of 1ung cancer with malignant pleural effusion(8/12).Though effu- sion CEA level was below 10ng/ml in 4 cases of lung cancer,the ratioe of effusion CEA and plas- ma CEA was equal to or big to two.It is suggested the detection of pleural effusion CEA and plasma CEA would help to differentiate benign and malignant pleural effusion.更多还原
