In Table 7, a multivariate analysis was performed for the risk of having nodal positivity in patients undergoing a definitive surgical procedure with a T1–T2 tumor <2 cm and at least one lymph node examined. The results were adjusted for type of surgical resection. Age (p < 0.0001, HR = 1.036) and male sex (p < 0.0001, HR = 1.386) were significantly associated with positive nodes. Positive nodes were not associated with any ethnic or income group. As compared to Connecticut, a greater risk of positive nodes was found in Greater Georgia, Hawaii, and Utah. T2 tumor had a higher risk of positive nodes than T1 tumors (p = 0.0004, HR = 1.289). Patients without a married partner (p < 0.0033, HR = 1.376) or without insurance (p < 0.0003, HR = 1.376) were more likely to have positive nodes. Right lower lobe location (p < 0.0353, HR = 1.185) was associated with a higher likelihood of positive nodes than the right upper lobe location. As compared to patients with adenocarcinoma, adenosquamous cell (p < 0.0316, HR = 1.416), large cell (p < 0.0252, HR = 1.426), and squamous cell carcinomas (p = 0.0437, HR = 1.149) had a higher risk of having positive nodes. Using well-differentiated tumors as a reference, nodal positivity was higher in patients having poorly differentiated (p < 0.0001, HR = 2.157), moderately differentiated (p < 0.0001, HR = 1.784), and unknown differentiated tumors (p < 0.0001, HR = 1.802). Number of nodes examined was not associated with nodal positivity. Nodal positivity was less likely in years 2010–2012 (p = 0.0427–0.0027), with a progressively decreased HR (0.821–0.0027).
