摘要: Elevated pleural fluid (PF) and plasma (PL) carcinoembryonic antigen (CEA) levels (ng/ml) were more frequently found with malignant than benign exudative effusions, but a low true-positive rate for malignancy in general. Adenocarcinomatous effusions differed from other the frequency degree of elevation PF PL CEA levels. A > 20 had sensitivity 91 percent specificity 92 as screening test adenocarcinomatous effusions. >55 or >10 present only 98 specific adenocarcinoma.
