Developmental phase



Assessment

Primary outcomes

Calculation of diagnostic yields for each method with endobronchial ultrasound bronchoscope for hilar and mediastinal lesions and hilar and mediastinal lymph node.

Key secondary outcomes

1. Evaluation of diagnostic yields by biopsy devises
2. Evaluation of adverse events associated with biopsies
3. Evaluation of the relationship between diagnostic yields and flow cytometry
4. Evaluation of the relationship between diagnostic yields and rapid on-site cytological evaluation (ROSE)
5. Evaluation of the relationship between diagnostic yields and the number of biopsies and tissue specimens
6. Evaluation of the relationship between target lesion sizes and diagnostic yields
7. Evaluation of diagnostic yields for EBUS-TBNA alone versus EBUS-TBNA preceded by EBUS-IFB/MFB or EBUS-TMC
8. Evaluation of diagnostic yields for EBUS-TBNA alone versus the combined diagnostic yields of EBUS-TBNA with EBUS-IFB/MFB and EBUS-TMC
