Title: Clinical significance of expression of cyclooxygenase-2 and vascular endothelial growth factor in pleural effusion

To assess the significance of COX-2 and VEGF in the differential diagnosis of benign and malignant pleural effusions by detecting their levels in pleural effusion.
Methods
Fifty-eight cases of pleural effusion were collected at our hospital, including 48 cases of malignant pleural effusion and 10 cases of benign pleural effusion. Expression levels of COX-2 and VEGF in pleural effusions were detected by ELISA and compared between benign and malignant pleural effusions.
Results
The expression levels of COX-2 and VEGF had no significant association with gender or age in both 48 cases of malignant pleural effusion and 10 cases of benign pleural effusion (P>0.05). The average COX-2 and VEGF levels were (788.04 ± 128.85) U/L and (365.27 ± 80.63) ng/L, respectively, in the malignant pleural effusion group, and the corresponding values in the benign pleural effusion group were (366.92 ± 41.08) U/L and (114.67 ± 15.69) ng/L. COX-2 and VEGF levels in malignant pleural effusion were significantly higher than those in benign pleural effusion (P<0.001).
Conclusion
COX-2 and VEGF expression levels are higher in malignant pleural effusion than in benign pleural effusion, and they may serve as prognostic factors to distinguish between benign and malignant pleural effusions.
