DR4 expression, like pathological grade and clinical stage, is significantly associated with poor survival of lung adenocarcinoma patients. A, Analysis of the association between DR4 expression and clinico-pathological features of lung adenocarcinomas (n = 242). Chi-square test was used to calculate statistical significance. LNM, lymph node metastasis. B, Representative images of DR4 staining. C, Kaplan-Meier survival analyses of the impact of DR4 expression, pathological grade and clinical stage on the survival of lung adenocarcinoma patients.
