Tumor marker CEA, CA125, CA199 in the identification of malignant pleural effusion application

Objective To compare the pathology and cytology, pleural effusion observed in the CEA and CA199, CA125 levels to explore three types of tumor markers for malignant pleural effusion in the differenti-al diagnosis. Methods The selected 36 cases of patients with benign pleural effusion and 29 cases of patients with malignant pleural effusion. The use of fully automated chemiluminescence detection of all people selected in the pleural effusion CEA and CA199, CA125 levels and screening tests commonly used statistical indicators to e-valuate their differential diagnosis. Results malignant pleural effusion group CEA, CA125, CA199 level (117.83±139.43)μg/L, (51.26±22.71 U/ml), (138.29±152.31) U/ml were significantly higher than benign pleural effusion group (2.89±7.21)μg/L, (17.12±9.23) U/ml, (23.36±37.84)U/ml,(P<0.05). Screening results showed that a simple detection sensitivity of the three markers were lower, with sensitivity of the CEA 58.6 percent for the highest CA199 specificity of 94.4% percent for the highest of the three markers combined detection sensi-tivity as high as 89.7% P<0.01,specificity 97.2%. Consistency in the diagnosis of the three markers combined detection of Kappa as the supreme value of 0. 875. Conclusion Detection of a separate CEA, CA125, CA199 sen-sitivity of the CEA high CA199 more specific joint detection of CEA,CA125 ,CA199 may have a sensitivity of the effect of superimposed significantly improve the diagnosis of malignant pleural effusion validity. Can be used as be-nign and malignant pleural effusion differential diagnosis of secondary indicators. Key words: Tumor;  Immunology;  Pleural effusion
