Abstract:
Objective To explore the difference of serum and pleural effusion CEA ,CA125 and CA199 levels in benign and ma‐lignant pleural effusions to accumulate the practical experience for clinical diagnosis .Methods 125 patients with pleural effusion in this hospital from February 2010 to March 2014 were performed the retrospective analysis and divided into the benign group(49 ca‐ses) and malignant group(76 cases) according to the nature of the fluids .The etiology composition ,pleural effusion and serum tumor markers levels were recorded in the two groups and at the same time the diagnosis efficiency of the tumor markers in pleural effusion was calculated .Results The specificity of the combined detection of CEA ,CA125 and CA199 for diagnosing benign and malignant pleural effusion was 90 .6% ,the sensitivity was 95 .1% ,the positive predictive value was 90 .2% ,negative predictive val‐ue was 95 .3% and accuracy was 92 .7% ,which were higher than those of the single index detection and any 2‐marker combined de‐tection .Conclusion The combined diagnosis of CEA ,CA125 and CA199 in pleural effusion conduces to the assisted diagnosis of be‐nign and malignant pleural effusion .
