The status of lymph node involvement is a major component of the TNM staging system. The N categories for lung cancer have remained unchanged since the fourth edition of the TNM staging system, partly because of differences in nodal mapping nomenclature, partly because of insufficient details to verify possible alternative approaches for staging. In preparation for the rigorous analysis of the International Association for the Study of Lung Cancer database necessary for the ninth edition TNM staging system, members of the N-Descriptors Subcommittee of the International Association for the Study of Lung Cancer Staging and Prognostic Factors Committee reviewed the evidence for alternative approaches to categorizing the extent of lymph node involvement with lung cancer, which is currently based solely on the anatomical location of lymph node metastasis.

- Low-dose computed tomography (LDCT) screening is effective in reducing lung cancer deaths, but existing eligibility criteria may overlook risks for women and racial minorities.
- A study compared different screening criteria, showing that expanding eligibility significantly increased the number of eligible individuals, particularly among women and black individuals.
- By adjusting the criteria, more lung cancer cases were detected, with 37% more individuals identified as having the disease when using the updated guidelines that allowed longer quit durations and fewer pack-years of smoking.
Background: Previous studies reported racial and socioeconomic disparities in receipt of curative-intent surgery for early-stage non-small cell lung cancer (NSCLC) in the United States. We examined variation in receipt of surgery and whether the racial disparity varies by state.
Methods: Patients in whom stage I or II NSCLC was diagnosed from 2007 to 2011 were identified from 38 state and the District of Columbia population-based cancer registries compiled by the North American Association of Central Cancer Registries.
