Forty four percent of patients with pathologic node negative (pN0) non-small cell lung cancer (NSCLC) die within 5 years of curative-intent surgery. Heterogeneity in pathologic nodal examination practice raises concerns about the accuracy of nodal staging in these patients. We hypothesized a reciprocal relationship between the number of lymph nodes examined and probability of missed lymph node metastasis, and sought to identify the number of lymph nodes associated with the lowest mortality risk in pN0 NSCLC. We analyzed resections for first primary, pN0 NSCLC in the United States Surveillance, Epidemiology, and End Results database from 1998 to 2009, with survival updated to December 31, 2009. In the 24,650 eligible patients, there was a significant, sequential reduction in mortality risk with examination of more lymph nodes. The lowest mortality risk occurred in those with 18 – 21 lymph nodes. Hazard ratio for all-cause mortality was 0.65, 95% confidence interval 0.57 – 0.73; for lung cancer specific mortality, 0.62, 0.53 – 0.73; p<.001 for both. The median number of lymph nodes examined was only 6. Lymph node evaluation falls far short of optimal in patients with resected ‘pN0 NSCLC’, raising the odds of under-estimation of long-term mortality risk, and failure to identify candidates for post-operative adjuvant therapy. This represents a major quality gap, for which corrective intervention is warranted.
