In lung adenocarcinoma samples, multivariate analysis showed that the following factors were independently associated with longer survival: high expression of E-cadherin (HR, 2.756; 95% CI, 1.347–4.165), low expression of vimentin (HR, 2.627; 95% CI, 1.158–4.096), low expression of Slug (HR, 3.241; 95% CI, 1.873–4.609), and low expression of Twist (HR, 2.976; 95% CI, 1.882–4.071) (Table 6). The gene discussed is TWIST1; the disease is lung adenocarcinoma.
