Diagnostic value of survivin and CEA in pleural effusion in detecting lung cancer
Objective To evaluate the diagnostic value of survivin and CEA in pleural effusion (PE) in detecting lung cancer. Methods CEA and survivin in PE were measured in 77 patients with malignant PE and 72 patients with benign PE. To evaluate diagnostic value of CEA and survivin by receiver operating characteristic (ROC) curve. Results At the optimum cut-off value, survivin and CEA of sensitivity were 80. 5% and 71. I% , and their specificity were 86. 1% and 84. 7%, respectively. Sensitivity and specificity in parallel tests were 94. 4% and 72. 9%, and were 57. 5% and 97. 8% in serial tests. Conclusions Combined assay of survivin and CEA seems to be better than survivin or CEA alone to diagnose lung cancer.
