There were 2354, 3367, 1638, 75, 87\u2009585, 42\u2009056, 19\u2009246, and 13\u2009069 cases in the group of superficial tumors of any size with invasive component limited to bronchial wall (T1\u2010bronchus), tumors involving main stem bronchus \u22652\u00a0cm from carina (T2\u2010main bronchus [\u22652\u00a0cm]), tumors involving main stem bronchus &lt;2\u00a0cm from carina (T2\u2010main bronchus [&lt;2\u00a0cm]), tumors with carina invasion (T4\u2010carina), T1, T2, T3, and T4, respectively. Multivariable Cox analysis indicated that T1\u2010bronchus patients had the best prognosis; T2\u2010main bronchus (\u22652\u00a0cm) and T2\u2010main bronchus (&lt;2\u2009cm) patients had similar prognosis both in the entire cohort and in several subgroups. Survival curves showed that T1\u2010bronchus and T1 patients had similar survival rates; the survivals of T2\u2010main bronchus patients regardless of the distance from carina were comparable to those of T2 patients, and the survivals of T4\u2010carina patients were also similar to those of T4 patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our results
