摘要
Abstract
Objective To evaluate the diagnostic value of 1,3-β-D-dextran in non-blood samples for radioactive pulmo-nary fungal infection. Methods The differences of the expression of 1,3-β-D- dextran(1,3-beta-D-glucan,BG) in blood,airway secretions and pleural effusion of lung cancer patients after radiotherapy were analyzed. Results G test results of different speci-mens were different in the diagnostic efficacy of the patients with radioactive pulmonary fungal infection. Sensitivity,accuracy and specificity of blood samples were the highest. And the positive predictive value and negative predictive value were optimal for the pleural effusion. Conclusion In the positive judgement threshold of G test is ≥10pg/mL,G test results of pleural effusion and airway secretions could detect lung fungal infection in patients with lung cancer after radiotherapy.关键词
