用放射免疫方法测定１６例癌性胸液和４２例结核性胸液的ＣＥＡ值，结果两组胸液的ＣＥＡ值（ｘ±ｓ）分别为５０．１４±２７．９１和１０．３±４．１５（μｇ／Ｌ）。以胸液的ＣＥＡ值＞１５μｇ／Ｌ为诊断癌性胸液的界值，癌性胸液组阳性率为８１．２５％（敏感性），特异性为９２．８６％，结核性胸液组阳性率为７．１％，经统计学处理两组间差异有显著性（Ｐ＜０．０１）。表明胸水的ＣＥＡ测定对癌性与结核性胸液的诊断与鉴别诊断有较大的临床实用价值。
Radioimmunoassay was used to measure the CEA values of 16 cases of malignant pleural effusion and 42 cases of tuberculous pleural fluid. The CEA values (x±s) of the thoracic fluid in the two groups were 50.14±27.91 and 10.3±4, respectively. .15 (μg/L). The CEA value of pleural fluid>15μg/L was used as the cutoff for the diagnosis of cancerous pleural fluid. The positive rate of cancerous pleural fluid was 81.25% (sensitivity), and the specificity was 92.86%. Tuberculous pleural fluid group The positive rate was 7.1%. There was a significant difference between the two groups (P<0.01). It shows that CEA determination of pleural effusion has great clinical practical value in the diagnosis and differential diagnosis of cancerous and tuberculous pleural fluid.
