ABSTRACT
Objective Methods To explore the value of VEGF levels in serum and pleural effusion for diagnosis of benign and malignant tumors, and evaluate clinical value of VEGF-A, C, D in malignant pleural effusion.Methods Serum and pleural effusion of 34 cases patients with lung cancer were collected in our hospital, the application of ELISA method for the detection of VEGF level in serum and pleural effusion in patients with lung cancer and with benign pleural effusion.VEGF-A, C, D levels were detected.Results VEGF levels in serum and pleural effusion in malignant group were significantly higher than those in benign group(P<0.05).In addition, patients with lung cancer before initial treatment, the VEGF levels in serum and pleural effusion of distant metastasis group were significantly higher than those of without distant metastasis group(P<0.05).There was a correlation between the level of VEGF and the malignant pleural effusion(r=0.878, P<0.05).No correlation existed between VEGF level and benign pleural effusion.The content of sVEGF-A in serum had no statistical difference in cancer group and benign group.Effusion supernatants of pVEGF-A content in lung cancer group were higher than those in benign effusion group(P<0.05).pVEGF-A and sVEGF-A levels were similar in benign effusion group. Effusion supernatants pVEGF-A in malignant group was higher than that in benign effusion group(P<0.05).pVEGF-A was significantly higher than that of sVEGF-A in malignant effusion(P<0.05).Serum VEGF-C, VEGF-D content had no significant difference between cancer group and benign group. pVEGF-C, pVEGF-D content had no significant difference between cancer group and benign group.Conclusion Level of VEGF in serum and pleural effusion detection would help to diagnose and differentially diagnose benign and malignant pleural effusion.Effusion VEGF-A is different in benign and malignant effusion, which may become benign and malignant effusion tumor markers.
