Review Meta Analysis
Endobronchial ultrasound-guided transbronchial needle biopsy for the diagnosis of intrathoracic lymph node metastases from extrathoracic malignancies: a meta-analysis and systematic review.
Intrathoracic lymph node metastases in patients with extrathoracic malignancies are a common clinical manifestation. Several studies evaluating intrathoracic lymph node metastases in patients with extrathoracic malignancy by using the endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) have been reported. The objective of this meta-analysis is to investigate the diagnostic value of EBUS-TBNA for diagnosing intrathoracic lymph node metastases in patients with extrathoracic malignancies. ⋯ The overall DOR was 179.77 (95% CI: 66.29-487.50). The area under the SROC curve and the diagnostic accuracy were 0.9247 and 0.8588, respectively. Evidence gathered from studies of moderate quality reveals a high degree of diagnostic accuracy of EBUS-TBNA for diagnosing intrathoracic lymph node metastases in patients with extrathoracic malignancies.
