Overexpression of miR-483-5p predicts venous thrombo-embolism onset in patients with lung cancer especially in high BMI cases
Background: Venous thromboembolism (VTE) is a common complication in patients with lung cancer. The important roles of microRNAs (miRNAs) in VTE have emerged, however, studies about the roles of miRNAs in VTE remain scarce. This study aimed to measure the expression of miR-483-5p in lung cancer patients with VTE, evaluate whether miR-483-5p could predict VTE onset in patients, and further evaluate its predictive value in patients with different BMI values. Methods: A total of 170 patients with lung cancer were recruited in this study, including 70 patients with VTE, and 110 patients with non-VTE. The expression of miR-483-5p was detected by quantitative real time PCR. Receiver operating characteristic analysis was used to screen VTE patients from non-VTE patients. Whether miR-483-5p was independently associated with VTE onset in lung cancer patients was evaluated by univariate and multivariate logistic regression analyses. Results: miR-483-5p was higher in VTE patients than that in non-VTE patients. miR-483-5p was correlated with body mass index (BMI), hypertension, C-reactive protein (CRP), and platelet count in VTE patients. In addition, miR-483-5p had high diagnostic value to differentiate between VTE patients and non-VTE patients and served as an independent biomarker in predicting the VTE onset in lung cancer patients. Moreover, miR-483-5p had the highest diagnostic accuracy to screen VTE patients from non-VTE patients in patients with high BMI values. Conclusion: miR-483-5p, increased in VTE patients, can independently predict VTE onset in lung cancer patients especially in patients with high BMI values.
