Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary endpoint: 1. The suitability rate for the assessment of PD-L1 expression on the cell block preparation with the EBUS/EUS-B 22 G TBNB Boston Acquire** needle vs 22 G TBNA Boston Scientific standard needle of mediastinal/hilar nodal or tumor aspirates in patients with a final diagnosis of lung cancer. Cell block specimens will be considered suitable if more than 100 tumor cells are present in the specimen. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Cumulative length tissue core 2. Suitability for molecular analysis/next generation sequencing of 22 G TBNB vs 22 G TBNA needles 3. Sample adequacy(defined as the presence of lymphocytes or atypical cells or other pathognomic characteristics (e.g. granulomas)) 4. Sample quality using Mair*s objective scoring system 5. Sample bloodiness 6. Diagnostic sensitivity for mediastinal/hilar nodal staging (defined as the proportion of patients that have N2/N3 disease diagnosed by EBUS-EUS-B, relative to the total number of patients with a final diagnosis of N2/N3 disease as determined by the reference standard) 7. Diagnostic sensitivity for malignancy (defined as the proportion of patients that have malignancy diagnosed by EBUS/EUS-B, relative to the total number of patients with a final diagnosis of malignancy as determined by the reference standard) 8. Yield for diagnosing malignancy in the subgroup of patients with a centrally located lung tumor (defined as the proportion of patients that have malignancy diagnosed by EBUS/EUS-B, relative to the total number of patients with a final diagnosis of malignancy) 9. Complication rate 10. Procedure duration 11. Endoscopist satisfaction of needle use | — |
