3. Fig 2
Changes in cIII-N2 over time. The progressive increase in the number of cIII-N2 cases (black line) follows the increase in number of The Society of Thoracic Surgeons (STS)-General Thoracic Data Base participants (GTSD) (dashed line). For comparison, the number of patients having operations for cIII-N2 lung cancer in the National Cancer Database (NCDB) is shown (gray line). The NCDB captures approximately 65% of newly diagnosed lung cancer in the United States [8].

Staging evaluations. The prevalence (y-axis) of (A) noninvasive and (B) invasive staging evaluations is shown for patients in the “full staging cohort” (as described in Patients and Methods) treated with upfront surgery or with induction therapy. (CT = computed tomography; EBUS = endobronchial ultrasound; PET = positron emission tomography.)

Comparison of the operative mortality rate in the linked subset of patients. The mortality rate at 90 days was available for the subset of patients aged older than 65 that were able to linked to Medicare data. The 90-day mortality rate is shown across three procedures, stratified according to whether patients were treated with upfront surgery (gray bars) or induction therapy (black bars). For comparison, the 30-day mortality, a composite of The Society of Thoracic Surgery General Thoracic Surgery Database (STS-GTSD) and Medicare data, is shown (white bars).
