Abstract
Nonexamination of lymph nodes is an extreme example of the variability of pathologic nodal staging of non-small cell lung cancer. We compared the prevalence, characteristics, and survival of patients without lymph nodes (pNX) to patients with documented pathologic N0 and pathologic N1 non-small cell lung cancer.
