Jiang L, Huang W, Liu J, et al. - The diagnostic precision of endobronchial ultrasound-guided transbronchial needle aspiration and endoscopic ultrasound-guided fine-needle aspiration for restaging the mediastinum after induction treatment in patients with lung cancer was investigated. Searching Embase and PubMed databases from conception to March 2019, researchers included a total of 10 studies consisting of 558 patients. They performed restaging of all patients by endobronchial ultrasound-guided transbronchial needle aspiration, endoscopic ultrasound-guided fine-needle aspiration, or both. For endobronchial ultrasound-guided transbronchial needle aspiration and endoscopic ultrasound-guided fine-needle aspiration, the area under the hierarchical summary receiver operating characteristic curves were 0.85 (95% CI, 0.81-0.88) and 0.99 (95% CI, 0.98-1), respectively. Outcomes support the accuracy and safety of endosonography with lymph node sampling for mediastinal restaging of lung cancer.
