RETRACTED: Effect Evaluation of Bronchial Artery Embolization for Hemoptysis of Lung Cancer and Changes in Serum Tumor Markers and miR-34 Levels (Retracted Article)

The clinical efficacy, serum tumor markers, and miR-34 expression levels of bronchial artery embolization (BAE) in patients with lung cancer with hemoptysis are investigated. 92 patients with lung cancer hemoptysis treated in our hospital from January 2019 to December 2021 are randomly selected, and 92 patients are randomly divided into the conservative group and the BAE group according to the number table method, with 46 patients in each group. The efficacy, overall survival (OS) rate, coagulation function, hemoptysis volume, serum tumor markers, and miR-34 expression are compared among all groups at different time points. The experimental results show that the BAE treatment can promote the expression of miR-34 and inhibit the expression of tumor markers, so it can improve the efficacy of patients with lung cancer hemoptysis, improve the symptoms of hemoptysis and coagulation function, and prolong the life cycle of patients.
