To prospectively look at the utility of routine cervical mediastinoscopy (lymph node biopsy) in patients with clinically staged T2N0M0 NSCLC, as well as patients with clinically staged T1N0M0 NSCLC with a high maxSUV of the primary tumor on PET imaging.
Hypothesis #1: The prevalence of mediastinal lymph node metastases detectable by cervical mediastinoscopy is sufficiently low (<10%) to not support the routine use of this test in the study population.
Hypothesis #2: The preoperative detection of occult(hidden) N2 lymph node metastases by cervical mediastinoscopy in patients with clinically staged T2N0M0 NSCLC or T1N0M0 NSCLC with maxSUV >10 on PET does not provide a survival benefit when compared to detection of occult N2 lymph node metastases at the time of thoracotomy using nodal dissection or systematic sampling.

- Prevalence of occult N2/3 metastases in the study population [ Time Frame: After cervical mediastinoscopy is performed in all subjects, estimated completion of enrollment of all subjects is 12/2012. ]Prevalence of occult N2/3 metastases in the study population. This is the fraction of enrolled patients with N2/3 metastases detected by either mediastinoscopy or by systematic sampling/dissection.
- Sensitivity of cervical mediastinoscopy for clinically occult N2 metastases [ Time Frame: After cervical mediastinoscopy is performed in all subjects, estimated completion of enrollment of all subjects is 12/2012. ]Sensitivity of cervical mediastinoscopy for clinically occult N2 metastases. This is the number of patients with positive mediastinoscopy divided by the total number with N2/3 disease detected by either mediastinoscopy or by systematic sampling/dissection.
