Abstract:

Objective: To investigate the correlation between the expression level of VEGF in malignant pleural effusion and the therapeutic effect of local cisplatin combined with endostar perfusion in the thoracic cavity, as well as to explore other potential influencing factors. Methods: From January 6, 2022, to January 18, 2024, 60 patients with malignant pleural effusion who declined systemic chemotherapy and consented only to local thoracic treatment were included in the study group. Additionally, 30 patients with benign pleural effusion treated during the same period were randomly selected using a 2∶1 ratio via a random number table to form the control group. After complete drainage via closed thoracic drainage, the study group was categorized into an effective group (34 cases, 56.67%) and an ineffective group (26 cases, 43.33%) based on pleural effusion control. Levels of VEGF, carcinoembryonic antigen (CEA), and total protein in pleural effusion were measured before and after treatment. The VEGF and CEA levels in pleural effusion were stratified into high and low expression groups according to the median values. Concurrently, clinical data were collected, with the objective response rate serving as the dependent variable. Univariate analysis was conducted to identify factors potentially influencing treatment efficacy, followed by multivariate logistic regression analysis on variables found to be statistically significant. Results: The use of cisplatin combined with endostar for local thoracic perfusion significantly reduced the levels of VEGF and CEA in malignant pleural effusion. Pre-treatment median levels of VEGF and CEA were 792.96 (473.69, 959.45) pg/ml and 59.89 (4.92, 389.53) ng/ml, respectively. Post-treatment levels were 454.46 (353.97, 558.40) pg/ml for VEGF and 11.94 (3.64, 46.47) ng/ml for CEA. The differences were statistically significant (Z=5.703, P<0.001; Z=3.29, P<0.001). Univariate analysis of factors such as patient age, gender, primary tumor, pathological type, history of systemic treatment, distant metastasis, endovascular treatment history, presence of hemothorax, KPS score, VEGF levels in pleural effusion, CEA levels in pleural effusion, and total protein levels in pleural effusion indicated the following correlations with treatment efficacy: primary tumor (fisher exact probability method, P=0.023), pathological type (fisher exact probability method, P=0.034), treatment classification (χ2=8.688, P=0.003), distant metastasis (χ2=10.259, P<0.001), history of endovascular treatment (χ2=7.330, P=0.007), presence of hemothorax (χ2=5.831, P=0.016), VEGF levels in pleural effusion (Z=5.057, P<0.001), and CEA levels in pleural effusion (Z=4.446, P<0.001). Multivariate logistic regression analysis revealed that the expression levels of VEGF and CEA in pleural effusion significantly impacted the therapeutic response (OR=8.15, 95%CI: 1.588-41.840; OR=25.67, 95%CI: 3.713-177.394). Conclusion: The expression levels of VEGF and CEA in the pleural effusion of patients with malignant pleural effusion can serve as predictive biomarkers for treatment response and disease control.
