Summary
Brief summary (as posted)
In case of PET or CT based cN1 (suspected) NSCLC, ESTS guidelines propose mediastinal staging by echo-endoscopy OR mediastinoscopy. Recent data show a sensitivity of less than 50% for echo-endoscopy to detect N2 disease in cN1 NSCLC patients, while prevalence of mediastinal nodal disease was 24% (unpublished data Aster II).2 The investigators plan to perform a prospective multicentric observational study to measure the sensitivity of mediastinal staging by video-assisted mediastinoscopy (VAM) in cN1 operable and resectable (suspected) NSCLC patients.

- label
- VAM
- description
- Patients with operable and resectable cT1-2-selected T3 cN1cM0 NSCLC undergo VAM for mediastinal lymph node staging. After VAM, patients without tissue proof of N2/3 disease at surgical staging undergo a VATS or thoracotomy with systematic lymph node dissection during the same anaesthesia or at a later stage. Sensitivity, NPV and accuracy of staging with VAM will be calculated. Provided N2 lymph node metastases are proven by VAM the patient goes off study protocol and can further be assessed/treated according to local clinical practice.
Primary outcomes (1)
- measure
- Sensitivity of VAM
- timeFrame
- at surgery (VAM)
- description
- Sensitivity (%) of surgical mediastinal staging by video-assisted mediastinoscopy in clinical N1; true positives (TP) = cN1 and pN1 - false negatives (FP) = cN1 and pN2/3; sensitivity is calculated as TP / (TP+FN)
Secondary outcomes (1)
- measure
- Prevalence of N2/3 disease after VAM
- timeFrame
- at surgery (VAM)
